Sales tax is a consumption tax charged by state and local governments on retail purchases of goods and some services. Unlike income tax which is based on earnings, sales tax is collected at the point of sale and varies dramatically by location—from 0% in tax-free "NOMAD" states (Oregon, Montana, New Hampshire, Delaware, and Alaska) to over 11.45% in high-tax jurisdictions like Louisiana. Understanding sales tax rates by state helps you make smarter purchasing decisions and can save you hundreds of dollars annually on major purchases.
Crucially, sales tax is not flat across an entire state. Your final combined rate stacks the state base rate alongside county, city, and special district taxes. For example, California's state rate is 7.25%, but local additions bring its combined average to 8.82%. Similarly, New York City residents pay a combined 8.52% while upstate NY averages 4.52%. Always use the combined rate—not just the state rate—for accurate calculations.
Example: A $500 purchase at an 8.25% tax rate = $500 × 0.0825 = $41.25 tax, resulting in a $541.25 total. To reverse-calculate: $541.25 ÷ 1.0825 = $500 pre-tax.
Combined state and average local rates for major U.S. states:

Shopping tip: If you live near a tax-free state, making major purchases (electronics, appliances, furniture) there can save you 8-10% of the purchase price. For perspective, on a $5,000 purchase, buying in Louisiana costs $475 more in taxes than shopping in tax-free Oregon.
Common exemptions that can save you money on everyday purchases:
| Item Category | Typical Exemption Status | States with Full Exemption |
|---|---|---|
| Groceries (unprepared food) | Exempt in 32 states | CA, TX, NY, FL, PA, OH, MI, NJ, VA, MA, and 22 others |
| Prescription medications | Exempt in all 50 states | All states |
| Clothing | Exempt in 4 states | PA, NJ, MN, NY (under $110) |
| Over-the-counter medicine | Exempt in many states | NY, PA, NJ, CT, FL, TX, and others |
| Medical equipment | Exempt in most states | Wheelchairs, prosthetics, hearing aids in 45+ states |
| Baby products | Varies by state | Diapers exempt in CA, NY, NJ; formula exempt in most states |
Mistake: Using only the state rate. Fix: Always use the combined rate (state + county + city + special districts). A 6% state rate can become 10%+ with local additions.
Mistake: Assuming all items are taxed equally. Fix: Many states exempt groceries, clothing, medicine, or have reduced rates. Check your state's exemptions before budgeting.
Mistake: Forgetting online purchase taxes. Fix: Since 2018 (South Dakota v. Wayfair), most online purchases include sales tax based on your delivery address. Factor this into price comparisons.
Mistake: Missing tax-free shopping periods. Fix: Many states offer tax-free weekends, such as back-to-school tax holidays in August or hurricane preparedness events in May. Plan major purchases around these dates to save hundreds.
Mistake: Not claiming exemptions for business purchases. Fix: If buying for resale, get a resale certificate from your state to avoid paying tax on inventory you'll collect tax on later.
| Item Price | Oregon (0%) | Florida (7%) | California (8.8%) | Louisiana (11.45%) |
|---|---|---|---|---|
| $100 | $100.00 | $107.00 | $108.80 | $111.45 |
| $500 | $500.00 | $535.00 | $544.00 | $557.25 |
| $1,000 | $1,000.00 | $1,070.00 | $1,088.00 | $1,114.50 |
| $5,000 | $5,000.00 | $5,350.00 | $5,440.00 | $5,572.50 |
On a $5,000 purchase, you save $572.50 shopping in Oregon vs. Louisiana—more than enough to justify an intentional shopping trip for major household purchases.
Sources & Methodology: State and local tax rates compiled from Tax Foundation, state revenue department data, and sales tax compliance databases. Rates reflect January 2026 data.

Sales Tax = Purchase Price × (Tax Rate ÷ 100). Total = Purchase Price + Sales Tax. Reverse: Pre-Tax = Total ÷ (1 + rate). Example: $500 at 8.25% = $41.25 tax, $541.25 total. Use your ZIP code combined rate — state + county + city + district taxes all stacked.
Five NOMAD states have no sales tax: Oregon, Montana, New Hampshire, Delaware, and Alaska (Alaska allows local taxes up to 7.5%). On a $2,000 laptop, shopping in Oregon saves $176 vs California and $229 vs Louisiana. Shopping trips are worthwhile for purchases over $1,000.
Louisiana has the highest at 11.45% (4.45% state + 7% average local). Tennessee is second at 9.55%, Arkansas third at 9.46%, Washington fourth at 9.29%, Alabama fifth at 9.25%. The national average combined rate is approximately 7.0%.
Divide the total by (1 + rate as decimal). Example: $108.25 total ÷ 1.0825 = $100 pre-tax, $8.25 tax paid. Useful for expense reports, business accounting, and verifying checkout charges — especially for cross-state online orders.
Yes. Since South Dakota v. Wayfair (2018), online retailers collect tax based on your delivery address. Amazon, eBay, Etsy, and Walmart Marketplace are marketplace facilitators — they collect and remit automatically. The rate applied is your local combined rate, not the seller's state rate.
Prescription drugs are exempt in all 50 states. Groceries are exempt in 32 states including CA, TX, NY, and FL. Clothing is fully exempt in PA, NJ, MN, and NY (under $110). OTC medications are exempt in NY, PA, NJ, CT, FL, and TX.
The state rate is set by state government alone. The combined rate adds county, city, and special district taxes. Chicago pays 10.25% combined vs Illinois's 6.25% state rate. Always use the combined rate — your exact ZIP code determines it since neighboring ZIP codes can differ significantly.
