Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Sales tax | Pre-tax amount | Total (tax included) |
|---|---|---|---|
| Add tax: $1,200 · 7.53% | $90.36 | $1,200.00 | $1,290.36 |
| Remove tax: $1,290.36 · 7.53% | $90.36 | $1,200.00 | $1,290.36 |
| Add tax: $50 · 8.25% | $4.13 | $50.00 | $54.13 |
| Add tax: $25,000 · 6.0% | $1,500.00 | $25,000.00 | $26,500.00 |
| Remove tax: $300 · 9.5% | $26.03 | $273.97 | $300.00 |
How This Calculator Works
Pick the direction first. In add mode, enter the pre-tax purchase amount: the calculator multiplies it by the rate to find the tax, then adds it for the register total. In remove mode, enter the tax-included total from a receipt: the calculator divides by (1 + rate) to back out the pre-tax price — the correct method, since subtracting the rate from the total would overstate the tax. For the rate, the state selector loads a dated state average combined state + local figure; it is a starting point, not an address-level lookup, so type the exact city or county rate when you know it. County and city taxes stack on the state rate, so two stores a few miles apart can charge different rates.
The Formula
Sales Tax — Add or Remove
Rate is the combined state + local sales tax percentage; in remove mode the amount entered is the tax-included total
Worked Example
Add mode: on a $1,200 pre-tax purchase at a combined 7.53% rate, the tax is $90.36 and the register total is $1,290.36. Remove mode: starting from that $1,290.36 tax-included receipt at the same 7.53%, the pre-tax price backs out to $1,200.00 — dividing by 1.0753, not subtracting 7.53% (which would wrongly give $1,193.20).
Key Insight
Combined sales tax varies widely — from zero in a few states to over 9% in parts of others — and the published state average can differ from the rate at your register, because county and city taxes stack on top of the state rate. This tool is transparent about that: it never guesses your local rate from an address; it gives you the dated state average and lets you enter the exact city or county rate yourself.
How local taxes stack on the state rate — selected metro examples (cited as of 2024)
The combined rate you actually pay is the state rate plus every county, city, and special-district tax at the point of sale, so two stores a few miles apart can charge different rates. Pick your state above for its average, then adjust for your city.
Illustrative combined state + local rates in major metros, cited as 2024 examples (these city figures are editorial illustrations and do not come from the January 1, 2026 state-average table above; verify the current rate with the city or state revenue department): New York City, NY 8.875%; Los Angeles, CA 9.50%; Chicago, IL 10.25%; Boston, MA 6.25%; Seattle, WA 10.60%; Denver, CO 8.61%; Atlanta, GA 8.00%; Memphis, TN 9.75%; Philadelphia, PA 8.00%; Phoenix, AZ 8.70%. In no-tax states, Portland OR, Manchester NH, and Anchorage AK are all 0%.
For large purchases (cars, jewelry, electronics) the local layer can swing the total by hundreds of dollars, which is why border shopping and destination-based online rates matter.
Why 5 states have no sales tax
Five U.S. states have no state sales tax: Alaska, Delaware, Montana, New Hampshire, Oregon. Alaska allows local sales tax (Anchorage 0%, Juneau 5%, some Native Alaskan localities up to 9.5%); others have no sales tax at any level.
These states rely on other revenue sources: (1) DELAWARE — corporate franchise tax and incorporation fees fund substantial portion of state revenue; (2) MONTANA — natural resource taxes (coal, oil/gas extraction); (3) NEW HAMPSHIRE — high property taxes and limited business profits tax (but no income tax either); (4) OREGON — relatively high state income tax (up to 9.9%); (5) ALASKA — oil revenue via Alaska Permanent Fund.
Tax-free shopping economic benefit. Border counties in tax-free states benefit from cross-border shopping. Portland OR area attracts Washington residents (WA has high sales tax). Salem NH and Nashua NH attract Massachusetts residents. Delaware attracts shoppers from PA, NJ, MD. Economic impact substantial — these locations have disproportionate retail and shopping center development.
Online sales tax — South Dakota v Wayfair changed everything
Pre-2018: U.S. Supreme Court's Quill decision (1992) required online sellers to have physical presence ('nexus') in a state to collect that state's sales tax. Amazon and many online sellers escaped collecting sales tax in states without warehouses.
South Dakota v Wayfair (2018): Supreme Court overturned Quill. States can require online sellers to collect sales tax based on economic nexus (sales volume) rather than physical presence. Threshold typically $100K+ in state sales OR 200+ transactions annually.
Result: most major online retailers (Amazon, Walmart, Target) now collect sales tax in all states. Small online sellers may or may not, depending on whether they exceed state thresholds. Marketplace facilitator laws (in most states) require platforms like Amazon and eBay to collect sales tax on behalf of third-party sellers regardless of seller's nexus.
Consumer impact: online and brick-and-mortar pricing now generally includes sales tax equivalently. The pre-2018 'online discount' of escaping sales tax has largely disappeared for established online retailers.

Rates are population-weighted state + average local combined rates from the Tax Foundation snapshot, as of January 1, 2026. Five states — Alaska, Delaware, Montana, New Hampshire, Oregon — levy no statewide sales tax, though Alaska allows local sales taxes. Your exact rate depends on the city and county of the sale.
State average + manual rate vs address-level lookup tools
Sales tax calculators come in two designs. This one uses dated state averages plus a manually entered exact rate; compliance-grade tools resolve the rate from a full street address. Each fits a different job.
| Aspect | This calculator (state average + manual exact rate) | Address-level lookup tools (ZIP/address API) |
|---|---|---|
| How the rate is found | You pick a state to load its dated, population-weighted average combined rate, or type the exact city or county rate yourself. | The tool resolves the combined rate from a full street address against a maintained rate database (ZIP codes alone often straddle several tax jurisdictions). |
| Freshness | Snapshot from the cited source with a visible as-of date; no real-time claim. | Vendor-maintained databases updated on the provider's cycle; freshness depends on the vendor. |
| Transparency | Formula, rate source, and date are shown on the page; the math is verifiable by hand. | Rate provenance is usually opaque — you trust the provider's database. |
| Best for | Quick estimates, budgeting, checking a receipt, backing tax out of a total, comparing states. | Invoicing, tax collection, and filing, where the legally applicable local rate for a specific address is required. |
Frequently Asked Questions
How do I remove sales tax from a total?
Divide the tax-included total by (1 + rate). At 7.53%, a $1,290.36 receipt total divided by 1.0753 gives a $1,200.00 pre-tax price; the tax is the $90.36 difference. Do not subtract the rate from the total — the tax was charged on the smaller pre-tax base, so subtraction overstates it. The calculator's remove mode does this division for you.
Is this an exact ZIP-code sales tax lookup?
No. The state selector loads a dated, population-weighted state average combined rate (Tax Foundation), not a rate resolved from your ZIP code or address, and nothing here updates in real time. If you know the exact city or county rate for the point of sale, type it into the rate field and the math is then exact. For an address-level determination — needed for compliance, invoicing, or filing — use your state revenue department's rate lookup or a commercial tax engine.
What is a combined sales tax rate?
It is the state sales tax rate plus any local county and city sales taxes that apply at the point of sale. The combined rate is what actually determines the tax you pay.
Why is sales tax added at the register?
In the US, listed prices are typically pre-tax. Sales tax is calculated and added at checkout, so the final total is higher than the shelf or menu price.
Do all states charge sales tax?
No. A small number of states have no statewide sales tax, though local taxes may still apply. Enter the rate for the specific location of the sale.
Is sales tax charged on every item?
Not always. Many states exempt or reduce tax on groceries, prescription drugs, or clothing. Enter only the taxable portion of a purchase for an accurate result.
How do I find my sales tax rate?
Your state revenue department publishes current rates, and the combined rate depends on the exact address of the sale. The default here reflects the cited national average.
When is this calculator unreliable?
When using state rate without local additions (most U.S. cities add 1-4% local tax). Also unreliable when tax base differs from purchase price (some states exempt groceries, clothing, prescription drugs — actual taxable amount may be less than total purchase). For online purchases, sales tax is generally collected at delivery destination's combined rate per Wayfair decision.

Data Sources & Benchmarks
This calculator draws on 1 independent, dated source. The starting values for sales tax rate are taken from the benchmarks below and refresh whenever the snapshots are updated. The page binds one dataset: the Tax Foundation 'State and Local Sales Tax Rates, 2026' report (snapshot as of January 1, 2026), which supplies the average combined state + local rates behind the state selector and the 7.53% national-average default. Editorial citations (Tax Foundation, Avalara, FTA) provide institutional context for how U.S. sales tax is administered. These are dated rate snapshots, not a live feed.

Assumptions
- The entered rate is the combined state + local rate actually charged at the point of sale; the state selector supplies a dated, population-weighted state average as a starting point, not an address-level determination.
- The full amount entered is taxable — no exemptions, tax holidays, or reduced rates on part of the basket.
- In remove mode, the entered total includes sales tax at exactly the entered rate and nothing else (no tips, fees, or deposit charges).
- Rates are snapshots from the cited source as of the date shown; they do not update in real time.
Limitations & Disclaimer
This is an educational tool, not financial advice. It does not account for your personal circumstances, and no result is a guarantee.
- This is not a ZIP-code or address-level rate lookup — city, county, and special-district rates must be entered manually when they differ from the state average.
- Does not model exemptions or reduced rates (groceries, clothing, prescription drugs vary by state), so the taxable amount can be less than the purchase total.
- Mid-year local rate changes will not be reflected until the cited dataset snapshot is refreshed.
- Origin- vs destination-based sourcing rules for online and cross-border sales can change which jurisdiction's rate applies; verify against your state revenue department for compliance use.
Methodology & Review
Two directions, one rate. Add tax: sales tax = pre-tax amount × rate; total = pre-tax amount + tax. Remove tax: pre-tax amount = tax-included total ÷ (1 + rate); tax = total − pre-tax amount — division, not subtraction, because the tax was charged on the smaller pre-tax base. Rates are NOT looked up in real time and NOT resolved from a ZIP code or address: the state selector loads a dated, population-weighted state average (Tax Foundation), and the rate field accepts the exact city or county rate you enter manually. U.S. sales tax landscape (Tax Foundation snapshot, as of January 1, 2026): state rates 0% (DE, MT, NH, OR, AK) to 7.25% (CA); plus local rates 0-4.75%. Combined state+local rates: 0% (DE, MT, NH, OR) to ~11% (Chicago suburbs, Birmingham AL, Memphis TN). 45 states + DC have state sales tax; many cities and counties add local tax on top. Tax base varies: some states tax groceries, clothing, services; others exempt. RELIABILITY: Reliable for documented rate and purchase price. Less reliable when (a) state/local rates change (rates often adjust mid-year); (b) base differs from purchase price (some states exempt grocery, clothing, prescription drugs); (c) destination-based vs origin-based sourcing rules apply differently for online sales.
