What Are State Taxes?

State taxes are mandatory financial charges imposed by individual states on their residents and businesses to fund public services and infrastructure. These taxes vary widely across states in terms of rates, rules, and types. The revenue generated supports essential programs and operations, including education, healthcare, transportation, public safety, and social services.

State taxes are a vital component of state budgets, helping governments address regional needs that federal funding may not fully cover. Each state independently determines its tax structure, meaning there can be significant differences in the types of taxes levied and how they are applied.

Differences Between Federal and State Taxes

  • Jurisdiction: Federal taxes are uniform across the entire United States and are collected by the Internal Revenue Service (IRS). State taxes are determined and collected independently by each state.
  • Scope: Federal taxes primarily fund national-level programs such as Social Security, defense, and Medicare, while state taxes focus on localized services like schools, road maintenance, and emergency services.
  • Tax Types and Rates: Federal taxes generally include income tax, payroll tax, and excise taxes. States may impose additional taxes or offer exemptions that differ from federal rules. For example, some states have no income tax, while others rely heavily on it.
  • Collection and Enforcement: Federal taxes are governed by federal law, whereas state taxes follow state-specific legislation. Taxpayers must comply with both sets of regulations, making state tax obligations unique to each individual or business based on location.

Common Types of State Taxes

1. Income Tax
State income tax is levied on the earnings of individuals and businesses.

  • Individual Income Tax: Many states use a progressive tax system, where the tax rate increases with higher income levels, though some states use a flat tax rate where all income is taxed at the same percentage. Notably, states like Texas and Florida impose no income tax at all.
  • Corporate Income Tax: Businesses operating within a state are often required to pay income tax on their profits. This rate varies significantly, with states like South Dakota and Wyoming not imposing corporate income taxes.

2. Sales Tax
Sales tax is imposed on the sale of goods and services.

  • State and Local Variations: States set a base rate for sales tax, which can be supplemented by local jurisdictions like cities or counties. For example, California has a state sales tax of 7.25%, but local governments can add additional percentages, resulting in varying rates within the state.
  • Exemptions: Some states exempt necessities such as groceries, prescription medications, or medical equipment from sales tax to reduce the burden on residents.

3. Property Tax
Property taxes are based on the assessed value of real estate and sometimes personal property.

  • Assessment and Rates: Local governments typically handle property tax assessments. Rates are determined by the local millage rate, which represents the amount owed per $1,000 of assessed property value.
  • Purpose: Revenue from property taxes funds schools, police departments, fire services, and other community resources. States like New Jersey have the highest property tax rates, while Hawaii has the lowest.

4. Other Taxes

  • Corporate Income Tax: Imposed on businesses, this tax depends on the company’s profits and varies widely by state. Some states, like Nevada, do not impose a corporate income tax.
  • Capital Gains Tax: States may tax earnings from investments and asset sales. For example, Washington state taxes capital gains exceeding a certain threshold.
  • Excise Taxes: Applied to specific goods like gasoline, alcohol, and tobacco, excise taxes are often included in the purchase price. These taxes aim to discourage certain behaviors (e.g., smoking) or fund specific projects like road repairs.
  • Specialty Taxes: These can include estate taxes, inheritance taxes, or motor vehicle license taxes, depending on the state.

Basics of State Income Tax

Progressive vs. Flat Tax Systems

  • Progressive Tax Systems

    • A progressive tax system imposes higher tax rates on individuals with higher income levels. This structure is designed to be equitable, with wealthier taxpayers contributing a larger percentage of their income to state revenue.
    • Example: In California, the income tax rate ranges from 1% for incomes up to $10,412 to 12.3% for incomes exceeding $698,272 for single filers.
    • Pros: Helps reduce income inequality and fund programs that benefit lower-income residents.
    • Cons: Can discourage high-income earners from working or investing in the state.

  • Flat Tax Systems

    • A flat tax system applies a single tax rate to all taxpayers, regardless of income level.
    • Example: In Colorado, all income is taxed at a flat rate of 4.4%.
    • Pros: Simpler to calculate and administer, perceived as fair since everyone pays the same rate.
    • Cons: May disproportionately affect low-income individuals, as the same percentage represents a larger portion of their income.

Residency Rules and Their Impact on Tax Liability

  • Resident Taxpayers

    • Residents are typically taxed on all income, regardless of where it is earned. States define residency based on criteria such as domicile (permanent home), time spent in the state, and significant connections (e.g., driver’s license, voting registration).

  • Non-Resident Taxpayers

    • Non-residents are taxed only on income earned within the state. For example, if you work in one state but live in another, you may owe taxes to the state where you work.

  • Part-Year Residents

    • Individuals who move between states during a tax year are considered part-year residents in both states. They report income earned while residing in each state and may qualify for credits to avoid double taxation.

  • Reciprocity Agreements

    • States with reciprocity agreements allow residents of one state to work in another without being taxed in both states. Instead, they pay taxes only in their state of residence.
    • Example: Maryland and Virginia have a reciprocity agreement to simplify tax obligations for cross-border workers.

Calculating State Income Tax

  1. Determine Gross Income

    • Gross income includes all earnings before any deductions. This encompasses wages, salaries, bonuses, freelance income, and investment earnings.

  2. Calculate Adjusted Gross Income (AGI)

    • AGI is determined by subtracting specific adjustments (above-the-line deductions) from gross income. Examples include contributions to retirement accounts, student loan interest, and health savings account (HSA) contributions.

  3. Subtract Deductions and Exemptions

    • Deductions: These reduce taxable income and may include medical expenses, mortgage interest, and state-specific deductions.
    • Exemptions: Personal exemptions reduce taxable income further, often based on the number of dependents.

  4. Apply Tax Rates

    • For progressive tax systems, identify the income bracket and apply the corresponding rate for each portion of your income.
    • For flat tax systems, multiply the taxable income by the flat rate.
    • Example (Progressive): In California, if your taxable income is $50,000, you pay:
      • 1% on the first $10,412 ($104.12),
      • 2% on income between $10,413 and $24,684 ($283.42),
      • 4% on income between $24,685 and $50,000 ($1,015.30).
      • Total: $1,402.84.

  5. Adjust for Tax Credits

    • Subtract eligible tax credits from your calculated tax liability. Credits directly reduce the amount you owe and may include education credits, energy-efficient home improvement credits, or earned income tax credits.

Special Considerations

  • Reciprocity Agreements

    • As mentioned earlier, these agreements simplify tax obligations for individuals who live in one state but work in another. Taxpayers need to submit appropriate forms to their employer to avoid withholding in the work state.

  • Common Credits and Deductions

    • Credits: Examples include child care credits, education credits, and renewable energy credits.
    • Deductions: Common deductions include charitable donations, retirement contributions, and certain medical expenses. Each state has specific guidelines, so it’s important to consult state tax resources.

‘Pro-Tip’

Understand Your State Tax Obligations: Research your state’s specific tax requirements, including income, sales, payroll, and property taxes. Bookmark your state tax agency’s website for updates.

State Sales Tax

Sales tax is a consumption tax imposed by states on the purchase of goods and services. It is typically calculated as a percentage of the purchase price and collected at the point of sale by retailers. The revenue generated from sales tax is used to fund public services, such as education, healthcare, and infrastructure development.

  • Impact on Goods and Services:
    Sales tax directly affects consumer spending by increasing the final cost of goods and services. For businesses, sales tax compliance involves collecting and remitting the correct amount to the state, which can be complex due to varying tax rates and exemptions.

State vs. Local Sales Tax Rates

  • State Sales Tax: Each state sets a base sales tax rate, which applies uniformly across the state. For example, Texas has a state sales tax rate of 6.25%.
  • Local Sales Tax: Local jurisdictions, such as counties, cities, or districts, may impose additional sales taxes on top of the state rate. The combined total of state and local rates determines the effective sales tax rate for a specific location.
  • Variation: States like Delaware, New Hampshire, and Oregon do not impose a state sales tax, while states like California have some of the highest combined rates.

Calculating Sales Tax

1. Identifying Taxable Goods/Services

  • Taxable Items: Sales tax typically applies to tangible personal property such as clothing, electronics, and furniture. Services may also be taxed in some states, such as repair work or cleaning services.
  • Non-Taxable Items: Many states exempt specific categories of goods and services, such as groceries, prescription drugs, and medical equipment. The rules vary by state, so it’s crucial to know what is taxable in your jurisdiction.

2. Applying Combined Sales Tax Rates

  • Step-by-Step Calculation:

    1. Determine the Taxable Amount: Identify the total purchase price of taxable items.
    2. Find the Combined Tax Rate: Combine the state and local sales tax rates applicable to the transaction.
    3. Calculate the Sales Tax: Multiply the taxable amount by the combined sales tax rate.
    4. Determine the Total Price: Add the sales tax to the original purchase price to find the total cost.

  • Example:
    If a customer purchases an item for $100 in a city with a state sales tax of 6% and a local sales tax of 2%, the calculation would be:

    • Taxable amount: $100
    • Combined tax rate: 6% (state) + 2% (local) = 8%
    • Sales tax: $100 × 0.08 = $8
    • Total price: $100 + $8 = $108

Exemptions and Special Rules

1. Essential Items Like Groceries or Prescription Drugs

2. Online and Out-of-State Purchases

  • Online Sales: Since the 2018 South Dakota v. Wayfair Supreme Court decision, states can require online retailers to collect sales tax, even if the retailer does not have a physical presence in the state.
  • Out-of-State Purchases: When residents buy taxable items from out-of-state retailers, they may owe use tax (equivalent to sales tax) to their home state if sales tax was not collected at the time of purchase.
    • Example: A consumer in California purchasing from a retailer in Oregon (a state without sales tax) may need to pay California’s use tax on the purchase.

‘Pro-Tip’

Register for State Tax Accounts: Ensure you’re registered for necessary state tax accounts, such as sales tax permits or payroll tax accounts. Most states require businesses to register before collecting or remitting taxes.

State Property Tax

1. Taxable Properties: Real Estate, Vehicles, and More
Property tax is a levy imposed on the ownership of certain properties, primarily real estate, by state and local governments. It can also apply to personal property like vehicles, boats, and business equipment in some states.

  • Real Estate: This includes residential homes, commercial buildings, and land.
  • Personal Property: Some states impose taxes on tangible personal property such as vehicles, machinery, and equipment. For example, Virginia charges a personal property tax on motor vehicles.
  • Business Property: Equipment, furniture, and inventory used for business purposes may also be subject to property tax in certain jurisdictions.

2. Role of Assessed Value and Millage Rates

  • Assessed Value:

    • The assessed value is the taxable value of a property, determined by local tax assessors.
    • It may represent a percentage of the property’s market value or the entire market value, depending on state rules.
    • Example: If a home has a market value of $300,000 and the state uses an assessed value of 70%, the taxable value is $210,000.

  • Millage Rates:

    • A millage rate is the amount of tax payable per $1,000 of assessed value. One mill equals $1 of tax for every $1,000 in assessed value.
    • Millage rates are set by local governments to fund specific services such as schools, public safety, and infrastructure.

Calculating Property Tax

1. Determining Assessed Property Value

  • Local governments or tax assessors evaluate the market value of a property and determine its assessed value based on state guidelines.
  • Adjustments may include reductions for depreciation, property condition, or other factors.
  • Example: A property with a market value of $400,000 and an assessment rate of 50% has an assessed value of $200,000.

2. Applying Millage Rates

  • Multiply the assessed value by the millage rate to calculate the property tax owed.
  • Millage rates are typically expressed in mills, where 1 mill equals $1 of tax per $1,000 of assessed value.

3. Example Calculation

  • Market Value: $300,000
  • Assessment Rate: 70%
    • Assessed Value = $300,000 × 70% = $210,000
  • Millage Rate: 20 mills (or 0.02)
    • Property Tax = $210,000 × 0.02 = $4,200

Exemptions and Adjustments

1. Common Exemptions

  • Homestead Exemption:

    • Reduces the taxable value of a primary residence. Some states offer fixed-dollar reductions, while others provide percentage-based exemptions.
    • Example: Florida offers a $50,000 homestead exemption, reducing the taxable value of eligible properties.

  • Senior Citizen Exemption:

    • Many states provide tax relief for senior citizens by reducing the taxable value or freezing property tax rates.
    • Example: Texas offers a $10,000 exemption for school taxes for residents aged 65 and older.

  • Veteran Exemption:

    • States may provide tax reductions or full exemptions for eligible veterans or surviving spouses.
    • Example: Illinois offers a tax exemption for disabled veterans, with the amount varying based on the disability rating.

2. Appeal Processes for Assessments
If a property owner believes their property has been overvalued or improperly assessed, they can appeal the assessment.

  • Steps to Appeal:

    1. Review Assessment: Obtain the property assessment record and verify its accuracy.
    2. File an Appeal: Submit an appeal form to the local tax authority within the designated timeframe, often 30 to 60 days after receiving the assessment notice.
    3. Provide Evidence: Present supporting documents, such as recent appraisals, comparable property values, or evidence of property condition.
    4. Attend a Hearing: A formal hearing may be scheduled to review the case and determine if an adjustment is warranted.

  • Example: In Maryland, property owners can file an appeal online, by mail, or in person, and decisions are typically reviewed by a county board of assessment appeals.

‘Pro-Tip’

Automate State Payroll Tax Calculations: Use payroll tools like TimeTrex to automatically calculate and withhold state payroll taxes, ensuring compliance with varying state rates and deadlines.

Other State Taxes

Corporate Income Tax

1. Overview and Variations Across States
Corporate income tax is levied on the profits of businesses operating within a state. The tax rate and structure can vary significantly across states, and some states do not impose this tax at all.

  • Flat vs. Progressive Rates:

    • Most states use a flat tax rate for corporate income, where all businesses pay the same percentage of their taxable income.
    • A few states, such as Iowa, use progressive tax systems with rates increasing as taxable income rises.

  • States Without Corporate Income Tax:

    • States like Nevada, South Dakota, and Wyoming do not impose a corporate income tax. Instead, they may rely on other forms of business taxation, such as gross receipts taxes.

  • Corporate Tax Rates:

    • Corporate tax rates range widely. For instance, North Carolina has a flat rate of 2.5%, the lowest in the U.S., while New Jersey’s top rate reaches 11.5%.

2. Calculating Taxable Income for Businesses
Corporate taxable income is calculated based on a company’s gross income, adjusted for allowable deductions and credits.

  • Step-by-Step Process:

    1. Determine Gross Income: Include revenue from all sources, such as sales, services, and investments.
    2. Subtract Business Expenses: Deduct operating costs, employee wages, and other eligible expenses.
    3. Adjust for State-Specific Rules: Some states have unique provisions, such as disallowing certain federal deductions or requiring additional adjustments.
    4. Apply the Tax Rate: Multiply the taxable income by the applicable corporate tax rate.

  • Example:

    • Gross income: $1,000,000
    • Deductible expenses: $700,000
    • Taxable income: $1,000,000 – $700,000 = $300,000
    • Tax rate: 6%
    • Corporate income tax: $300,000 × 0.06 = $18,000

Excise and Specialty Taxes

1. Taxes on Gasoline, Alcohol, and Tobacco
Excise taxes are applied to specific goods and are often included in the purchase price. These taxes are typically used to fund infrastructure or public health programs.

  • Gasoline:

    • States impose excise taxes on fuel to fund transportation and infrastructure projects.
    • Example: California has one of the highest gas taxes, currently exceeding $0.50 per gallon, while Alaska’s gas tax is among the lowest at $0.089 per gallon.

  • Alcohol:

  • Tobacco:

2. Capital Gains and Dividend Taxes

Key Points for Businesses and Individuals:

  • Excise taxes are often included in the product price, so consumers may not see the tax as a separate line item.
  • Capital gains and dividend taxes can significantly impact investment income, making it crucial to plan for potential liabilities.

‘Pro-Tip’

Stay on Top of Sales Tax Compliance: Determine which goods and services are taxable in your state. If you sell across state lines or online, understand nexus laws that may require you to collect and remit sales tax in other states.

State Tax Deductions and Credits

1. Reducing Taxable Income
Tax deductions lower your taxable income, which reduces the amount of income subject to taxation. By claiming deductions, you effectively shift part of your earnings into a lower tax bracket or reduce the overall taxable amount.

  • Example:
    If your taxable income is $50,000 and you claim $5,000 in deductions, your taxable income decreases to $45,000. Depending on the tax rate, this could result in significant savings.

2. Common Deductions
While deductions vary by state, some are widely recognized and frequently used:

  • Medical Expenses:

  • Retirement Contributions:

    • Contributions to state-recognized retirement accounts, such as IRAs or 401(k)s, may be deductible.
    • Example: New York allows deductions for contributions to state-sponsored retirement plans.

  • Mortgage Interest and Property Taxes:

    • Some states allow deductions for mortgage interest or property taxes paid during the year.
    • Example: Wisconsin offers deductions for property taxes paid on a primary residence.

  • Charitable Contributions:

    • Donations to qualifying charitable organizations can reduce taxable income.
    • Example: Colorado allows deductions for charitable donations if the taxpayer itemizes their deductions.

Exploring Tax Credits

1. Direct Reduction of Tax Liability
Unlike deductions, which reduce taxable income, tax credits directly reduce the amount of tax you owe. Credits can result in significant savings and, in some cases, refunds if the credit exceeds your tax liability.

  • Refundable vs. Non-Refundable Credits:
    • Refundable Credits: If the credit exceeds your tax liability, the excess is refunded to you.
    • Non-Refundable Credits: These only reduce your tax liability to zero and do not result in a refund.

2. Examples of State Tax Credits

  • Earned Income Tax Credit (EITC):

    • Designed for low- and moderate-income workers, the EITC provides a credit based on income and number of dependents. Many states offer their own version of the federal EITC.
    • Example: California’s EITC supplements the federal EITC for qualifying residents.

  • Child Tax Credits:

  • Energy-Efficiency Credits:

    • Some states provide credits for investments in renewable energy systems or energy-efficient home improvements.
    • Example: Oregon offers a tax credit for installing solar panels or other renewable energy systems.

  • Education Credits:

    • States may provide credits for tuition, student loan interest, or contributions to state-recognized education savings plans.
    • Example: Minnesota offers a refundable education credit for qualifying expenses related to K-12 education.

Maximizing Benefits

1. Researching State-Specific Options
Taxpayers should consult their state’s department of revenue website or a tax professional to identify available deductions and credits. Each state has unique rules, thresholds, and eligibility criteria.

  • Example: A resident in Georgia may qualify for credits related to job creation or rural hospital contributions that are not available in other states.

2. Keeping Accurate Records
To claim deductions and credits, proper documentation is essential. Maintain organized records of expenses, receipts, and relevant forms, such as:

  • Medical bills.
  • Charitable donation receipts.
  • Proof of contributions to retirement or education savings accounts.
  • Invoices for energy-efficient home improvements.

3. Timing and Strategy

  • Bunching Deductions: In years when your expenses are high, you may be able to “bunch” deductions (e.g., prepaying property taxes or making additional charitable contributions) to exceed the standard deduction threshold.
  • Maximizing Refundable Credits: Prioritize claiming refundable credits, as they offer the most direct financial benefit.

‘Pro-Tip’

Monitor State Tax Deadlines: Keep a calendar of state tax filing deadlines, including estimated payments, sales tax returns, and payroll tax submissions. Missing deadlines can result in penalties.

Filing State Taxes

1. Electronic Filing (E-Filing) vs. Paper Filing

  • E-Filing:

    • E-filing is the most efficient and widely used method for submitting state tax returns.
    • Benefits include:
      • Faster processing and quicker refunds.
      • Reduced risk of errors through automated calculations and data validation.
      • Enhanced security for sensitive information.
    • Example: States like New York and California offer free e-filing services for eligible taxpayers through their official tax portals.

  • Paper Filing:

    • Traditional filing involves downloading or requesting physical forms, completing them manually, and mailing them to the state tax authority.
    • Benefits include:
      • Accessibility for those without internet access or familiarity with digital systems.
      • A physical record of the return for personal files.
    • Drawbacks:
      • Slower processing times.
      • Higher likelihood of errors due to manual calculations.
    • Example: Taxpayers in Georgia can download Form 500 to file paper returns for individual income taxes.

2. Role of Tax Professionals

  • Tax professionals, such as CPAs or enrolled agents, provide expertise in navigating complex tax scenarios.
  • When to use a tax professional:
    • If you have multiple income sources, such as self-employment or rental income.
    • If you’re unsure of applicable deductions, credits, or exemptions.
    • For assistance with state-specific requirements or resolving disputes.
  • Benefits:
    • Minimizes errors and ensures compliance.
    • Identifies opportunities to reduce tax liability.

Deadlines and Extensions

1. Importance of Timely Submissions

  • Filing state taxes by the deadline avoids late penalties and interest charges.
  • States often synchronize filing deadlines with federal deadlines (e.g., April 15), but some states may have unique deadlines.
  • Filing on time ensures prompt receipt of refunds or application of credits.

2. How to Request Extensions

  • Most states offer extensions for filing returns, but extensions do not apply to tax payments. Taxes owed must still be paid by the original deadline to avoid penalties.

  • Steps to Request an Extension:

    1. Submit an extension request form (if required) before the filing deadline.
    2. Pay estimated taxes owed to prevent interest or penalties.
    3. File the return by the extended deadline, usually 4-6 months later.

  • Key Considerations:

    • Even if an extension is granted, any underpayment of taxes by the original deadline may accrue interest.
    • Some states automatically grant extensions if you request a federal tax extension.

Estimated Tax Payments

1. Who Needs to Make Them

  • Estimated tax payments are required for individuals or businesses that expect to owe taxes not covered by withholding.

    • Common Scenarios:
      • Self-employed individuals or freelancers.
      • Business owners.
      • Investors with substantial dividend or capital gains income.

  • Thresholds:

    • Many states require estimated payments if expected taxes exceed a certain amount, typically $500-$1,000.
    • Example: In New Jersey, individuals owing more than $400 in state taxes must make quarterly estimated payments.

2. Calculating and Submitting Payments

  • Steps for Calculation:

    1. Estimate your annual taxable income and deductions.
    2. Apply the state’s tax rate to determine projected tax liability.
    3. Subtract any taxes already paid or withheld.
    4. Divide the remaining amount into quarterly installments.

  • Submission Methods:

  • Deadlines for Quarterly Payments:

    • Most states follow the federal schedule for estimated payments: April 15, June 15, September 15, and January 15 of the following year.

  • Avoiding Penalties:

    • To avoid underpayment penalties, ensure that each payment is at least:
      • 90% of the current year’s tax liability, or
      • 100% of the prior year’s liability (safe harbor rule).

‘Pro-Tip’

Leverage State Tax Deductions: Identify and claim state-specific deductions, such as business equipment purchases, rent, or energy-efficient upgrades.

Amending and Appealing State Taxes

Correcting Errors

1. Filing Amended Returns
If you discover an error or omission on a previously filed state tax return, you can correct it by filing an amended return. Common reasons for amending include reporting additional income, correcting deductions or credits, or fixing filing status errors.

  • Steps to File an Amended Return:

    1. Obtain the Correct Form: Each state has a specific form for filing amended returns.
      • Example: In California, use Form 540X to amend personal income tax returns.
    2. Indicate Changes Clearly:
      • Clearly outline the changes made, including updated amounts and explanations for the adjustments.
      • Attach supporting documents, such as corrected W-2s, updated 1099s, or revised deduction records.
    3. Submit the Amended Return:
      • File the form with the state’s department of revenue and include any additional payment due. If the amendment results in a refund, ensure all documentation is complete to avoid delays.
    4. Monitor Processing:
      • Amended returns may take longer to process than original filings. Track the status through your state’s tax portal if available.

  • Key Considerations:

    • Some states require you to amend your state return if you’ve amended your federal return and the changes affect your state taxes.
    • Check the state’s statute of limitations, as most allow amendments only within 3-4 years of the original filing date.

2. State-Specific Forms and Procedures

Appealing Tax Assessments

1. Steps to Dispute Property or Income Tax Assessments
Taxpayers who disagree with a state tax assessment—such as property valuation or income tax liability—have the right to appeal the decision.

  • Disputing Property Tax Assessments:

    1. Review the Assessment: Obtain the property tax notice or valuation report from the local assessor’s office. Check for inaccuracies in property value, size, or condition.
    2. File an Appeal: Submit a formal appeal to the local tax authority or appeals board.
      • Example: In Washington, use the “Taxpayer Petition for Review of Property Valuation Determination” form.
    3. Provide Supporting Evidence:
      • Comparable property sales data.
      • Recent appraisals showing lower property value.
      • Photographs or reports of property condition discrepancies.
    4. Attend a Hearing: Present your case at a scheduled hearing before the board of appeals or review panel.

  • Disputing Income Tax Assessments:

    1. Understand the Discrepancy: Review the notice from the state tax department detailing the issue.
      • Common reasons include unreported income, disallowed deductions, or computational errors.
    2. Respond Promptly: Most states require appeals to be filed within a specified timeframe, often 30-60 days from receiving the notice.
    3. File an Appeal: Submit the necessary appeal form, along with a written explanation of why you disagree with the assessment.
    4. Submit Evidence:
      • Documentation of reported income.
      • Proof of eligibility for claimed deductions or credits.
      • Correspondence from employers or financial institutions to clarify discrepancies.
    5. Attend a Conference or Hearing: Some states offer an informal conference before a formal appeal hearing. Use this opportunity to resolve disputes without escalation.

2. Supporting Your Appeal with Evidence
To increase the likelihood of a successful appeal, gather strong evidence to support your claims.

  • For Property Tax Appeals:
    • Comparable property sales records.
    • Independent appraisals or market analysis.
    • Photos or repair estimates showing defects or damages.
  • For Income Tax Appeals:
    • Corrected tax forms (e.g., W-2s, 1099s).
    • Receipts or invoices for deductions and credits.
    • Correspondence from relevant financial or business entities.

‘Pro-Tip’

Track Local Tax Rates: Many states allow local jurisdictions to impose additional sales, income, or property taxes. Know the combined rates for all locations where your business operates.

What Is Sales Tax, and How Is It Calculated?

Sales tax is a consumption tax added to the price of goods and services.

  • Example: A $100 item with an 8% sales tax rate incurs $8 in sales tax.

Are There Exemptions to Sales Tax?

Yes, many states exempt items like groceries, prescription medications, and medical devices. Some states also have “tax holidays” during which specific items, such as school supplies, are tax-free.

How Is Property Tax Calculated?

  • Determine the property’s assessed value (often a percentage of market value).
  • Apply the local millage rate (tax per $1,000 of assessed value).
  • Example: A property with an assessed value of $200,000 and a millage rate of 20 mills owes $4,000 in property taxes.
