State rate table last reviewed: 2026-10-02. Local averages are approximate (Tax Foundation–style midyear figures) and change over time.
How this estimator works
Sales tax estimators look simple — multiply price by a percentage — until local option taxes, product exemptions, and origin-versus-destination sourcing rules enter the picture. This calculator keeps the math honest and limited:
State-only mode: Tax = Amount × State rate.
With approximate local: Tax = Amount × (State rate + Approximate average local rate).
Example (California, $100, state only): 100 × 7.25% = $7.25, total due with tax $107.25.
Example with approximate local average ~1.78%: combined ~9.03% → tax ≈ $9.03.
Your city might be higher or lower than the statewide average. Never treat the combined figure as an official remittance rate for a specific street address. When you change the state dropdown, the calculator swaps the rate block and the agency link — that state switch is intentional so you always see which DOR to verify against.
State rate table
The ten states below cover a large share of U.S. retail volume while keeping the table maintainable. Rates live in data/rates.json so mid-year updates can change numbers without rewriting every paragraph.
| State | State rate | Approx. avg local | Approx. combined | Agency |
|---|---|---|---|---|
| California (CA) | 7.25% | ~1.78% | ~9.03% | CDTFA |
| Texas (TX) | 6.25% | ~1.95% | ~8.20% | Comptroller |
| Florida (FL) | 6.00% | ~0.98% | ~6.98% | FL DOR |
| New York (NY) | 4.00% | ~4.54% | ~8.54% | NY Tax |
| Washington (WA) | 6.50% | ~3.07% | ~9.57% | WA DOR |
| Illinois (IL) | 6.25% | ~2.73% | ~8.98% | IL DOR |
| Pennsylvania (PA) | 6.00% | ~0.34% | ~6.34% | PA Revenue |
| Ohio (OH) | 5.75% | ~1.54% | ~7.29% | OH Taxation |
| Georgia (GA) | 4.00% | ~3.56% | ~7.56% | GA DOR |
| North Carolina (NC) | 4.75% | ~2.35% | ~7.10% | NC DOR |
Sales tax vs use tax (SMB basics)
Sales tax is generally collected by the seller on taxable retail sales sourced to a jurisdiction. Use tax may apply when you buy taxable tangible goods without paying the appropriate sales tax — classic examples include some out-of-state or marketplace purchases — and then store or consume them in your state. Reporting use tax is easy to overlook for new businesses. This calculator only multiplies a purchase amount by a selected rate; it does not decide whether an item is taxable, whether you have nexus, or whether marketplace facilitator rules already collected tax on your behalf.
What local averages leave out
- City, county, and special-district add-ons that differ block-by-block.
- Temporary district taxes for transit or projects.
- Cap rules (some states limit how high local rates may climb).
- Product-based exemptions (many groceries, prescription drugs, or manufacturing inputs).
- Origin-based versus destination-based sourcing for remote sellers.
Because of those gaps, every result card links the state agency page. Treat official lookup tools as the second step after this teaching estimate.
Worked examples
Texas $250 state-only: 250 × 6.25% = $15.63 tax; total $265.63.
Same purchase with approx. local: 250 × ~8.20% ≈ $20.50 tax — remember the local piece is an average, not Austin-specific or Dallas-specific.
New York state-only on $80: 80 × 4% = $3.20. Combined averages in NY are often driven more by local rates than by the state rate alone, which is why the optional local toggle matters for intuition building.
FAQ
Why isn’t ZIP lookup included?
Exact local rates need maintained jurisdiction data and frequent updates. We link each state DOR so you can look up the official rate for an address.
Are groceries or services taxed the same as general merchandise?
No. Exemptions and special bases vary widely by state. The estimator assumes a generic taxable amount that you enter.
Can I rely on this to configure ecommerce tax settings?
Use it as a teaching estimate only. Configure commerce platforms from official rate sources or certified tax providers.
Where are the machine-readable rates?
See /data/rates.json (also /assets/rates.json) with lastReviewed: "2026-10-02" for mid-year updates.
Official starting points
Begin with the agency link shown after each calculation, or browse the table above. Combined with the IRS mileage and CA overtime tools on this hub, the goal is literacy — not replacing a sales-tax compliance system.
Practical workflow for SMB owners
Use this estimator to build intuition: pick a state, try state-only versus approximate local, and notice how much of the combined rate is local in places like New York or Washington versus how little is local on average in Pennsylvania. Then open the linked department of revenue site and look up the rate for your actual warehouse, storefront, or customer address before you print invoices or configure a shopping cart.
If you sell into many states, economic nexus and marketplace facilitator laws may already obligate collection even without a physical office. Those rules change and are beyond a ten-state rate table. Pair this page with advice from a sales-tax specialist or a certified automated system when volume grows. MileagePayTools will keep lastReviewed current when we refresh the JSON; you still own the compliance decision for each invoice.
Finally, remember exemptions: resale certificates, agricultural exemptions, and nonprofit rules can zero out tax that a naive multiplier would charge. Always ask whether the item and the buyer are taxable before trusting any percentage — including ours.
