When making purchases—whether for personal use or business purposes—sales tax is often an unavoidable part of the final cost. But many taxpayers and business owners wonder: can the sales tax paid on these purchases be deducted on their federal tax return? The answer depends on several factors, including whether the expense is personal or business-related, how the item is used, and what election is made on the tax return.
This comprehensive guide breaks down the rules surrounding sales tax deductibility in the United States and offers clarity on when and how you can claim a deduction. If you’re a U.S. CPA firm or business navigating these complexities, partnering with expert offshore teams like PEAK Business Consultancy Services (PEAK BCS) can streamline your tax compliance process.

Sales Tax vs. Income Tax: Choosing the Deduction
For individual taxpayers filing Form 1040 and itemizing deductions, the IRS allows a choice between deducting either:
- State and local income taxes, or
- State and local general sales taxes
You cannot deduct both. This choice is reported on Schedule A (Itemized Deductions). Most people in states with no income tax—like Texas, Florida, or Washington—opt to deduct sales taxes instead of income taxes. Even if you live in a state with income tax, deducting sales tax may still make sense if you made large purchases such as a vehicle, home renovations, or high-value electronics in the tax year.
How to Determine Your Sales Tax Deduction
Option 1: IRS Sales Tax Tables
The IRS provides optional tables to estimate your general sales tax deduction based on your income level, filing status, number of dependents, and state of residence. You can use these tables and add any “big-ticket” purchases on top of the estimated amount.
Option 2: Actual Sales Tax Paid
Alternatively, you can track and deduct the exact amount of sales tax you paid during the year by keeping all your receipts. This method is more tedious but potentially more beneficial if your actual expenses exceeded the IRS’s estimates.
Deducting Sales Tax on Major Purchases
If you use the IRS’s optional sales tax tables, you are allowed to add the sales tax paid on large purchases to your deduction. These include:
- Cars, trucks, motorcycles, RVs, and boats
- Home building materials and renovations
- Aircraft (personal, not business-use)
Make sure to retain proper documentation such as receipts, invoices, and registration papers to justify these additions in case of an IRS audit.
Sales Tax Deductions for Businesses
For businesses, sales tax is generally not separately deductible because it’s included in the total cost of the purchase. However, in many cases:
- Sales tax on supplies and equipment is included in the asset’s cost and depreciated over time.
- Sales tax on inventory is considered part of Cost of Goods Sold (COGS).
- Sales tax paid on services may be deductible as a business expense if the service itself is deductible.
It’s essential for business owners and tax professionals to classify these costs accurately. Using tax preparation support from experienced teams like PEAK BCS ensures proper categorization and maximum deductions without IRS red flags.

Can You Deduct Sales Tax on a Personal Vehicle?
If you itemize deductions and choose to deduct sales tax instead of income tax, the sales tax paid on a new or used personal vehicle can be added to your standard sales tax deduction. This is especially advantageous in high-tax states or on expensive vehicles.
For vehicles used for business purposes, sales tax is part of the vehicle’s cost basis and must be capitalized and depreciated according to IRS rules (typically under MACRS).
Sales Tax on Meals, Clothing, and Everyday Items
These everyday purchases are already accounted for in the IRS’s optional sales tax tables. If you are tracking actual sales tax, you must retain receipts to document the tax paid on these small but cumulative purchases. This can be challenging and time-consuming, which is why many individuals prefer to use the standard tables.
State and Local Rules May Vary
While the IRS provides federal guidance, some states may have their own treatment for sales tax, especially in terms of business expense deductions, inventory cost treatment, or state tax credits. Always check with your state’s department of revenue or consult with a qualified tax advisor.
