US Sales Tax Overview

Local Tax Considerations
Many states allow local governments to impose additional sales taxes on top of state rates. These can significantly increase the total tax burden, especially in major metropolitan areas.
Business Tax Compliance
Businesses must understand nexus rules, which determine when they're required to collect sales tax in different states. This is especially important for e-commerce businesses.
- • Physical presence creates nexus
- • Economic nexus thresholds vary by state
- • Remote seller laws affect online businesses
- • Proper registration and filing are required
Sales Tax Deduction
Federal Income Tax Deduction
You can deduct sales tax from federal income tax if you itemize deductions. This is beneficial for taxpayers who made large purchases during the year, such as cars, weddings, or major appliances.
Record Keeping Requirements
The IRS requires detailed records of sales tax paid, including receipts and documentation. This can be tedious but may result in significant tax savings for high-spending taxpayers.
Standard vs Itemized Deductions
Most taxpayers choose the standard deduction, but those with large purchases may benefit from itemizing to claim sales tax deductions. Compare both options to maximize your tax savings.
Frequently Asked Questions
What's the difference between sales tax and VAT?
Sales tax is imposed only on the final consumer at the point of sale, while VAT (Value-Added Tax) is imposed at each stage of production. VAT is used in over 160 countries outside the US.
Do I need to collect sales tax for online sales?
It depends on nexus rules. If you have physical presence or meet economic nexus thresholds in a state, you must collect and remit sales tax for sales to customers in that state.
How often do sales tax rates change?
Sales tax rates can change annually or more frequently. States and local governments may adjust rates during budget cycles, so it's important to stay updated on current rates.
Can I deduct sales tax from my federal income tax?
Yes, if you itemize deductions, you can choose to deduct either state income tax or sales tax (but not both). This is beneficial for taxpayers who made large purchases during the year.
What products are exempt from sales tax?
Exemptions vary by state but commonly include prescription medications, food (in some states), educational materials, and certain medical supplies. Check your state's specific exemption list.
