Alaska has no state-level sales tax -- add local sales tax (if any applies where you are) onto a price, or reverse a tax-inclusive total.
Alaska's state base sales tax rate is pre-filled at 0% (as of September 17, 2026, per the Tax Foundation and U.S. Department of Labor). Most cities/counties add local sales tax on top, so your actual combined rate at checkout is often higher -- edit the rate below if you know your local combined rate, and always verify at your state's department of revenue for anything that matters.
Alaska does not levy a state-level sales tax (as of September 17, 2026, per the Tax Foundation and U.S. Department of Labor). Depending on where exactly you are, a local jurisdiction may still charge its own sales tax on top -- this tool pre-fills 0% as the state-level starting point, and you can edit the rate to your actual local rate if one applies.
Enter a pre-tax amount to add Alaska's sales tax onto it, or switch to "Reverse" mode and enter a tax-inclusive total to back out the pre-tax price. The rate field is pre-filled but fully editable.
Alaska is one of 5 jurisdictions in this data set with no state-level sales tax at all (Alaska, Delaware, Montana, New Hampshire, Oregon). Every other jurisdiction listed charges a state rate between 2.9% and 7.25%, with a simple unweighted average of about 5.66%.
Jurisdictions with the state rates closest to Alaska's are Delaware (0%), Montana (0%), New Hampshire (0%). 4 other jurisdictions (Delaware, Montana, New Hampshire, Oregon) charge exactly the same state rate. Keep in mind that a state rate is only the first layer: the number that matters for a real purchase is the combined rate at the spot where you buy.
For context, Alaska's general minimum wage is $14.00/hour -- see the Alaska minimum wage calculator for how far that goes after this tax.
Because Alaska's state rate is 0%, the state adds nothing to a price. If a local jurisdiction where you shop did charge a tax, for example a hypothetical 2%, a $200.00 purchase would carry $4.00 in tax for a $204.00 total -- enter that local figure in the rate field to model it.
In reverse mode at a 0% rate the pre-tax price equals the total, since nothing was added. Reverse mode is most useful when a local rate applies to you and you only have the tax-inclusive total from a receipt.
Taxable spending of $12,000.00 in a year carries $0.00 of Alaska state sales tax. Taxable spending of $24,000.00 in a year carries $0.00 of Alaska state sales tax. Taxable spending of $36,000.00 in a year carries $0.00 of Alaska state sales tax. For comparison, the same three spending levels at the 5.66% average state rate among taxing jurisdictions would come to $679.30, $1,358.61, $2,037.91 respectively, so the state-level saving in Alaska is the full amount shown. Only a share of household spending is actually taxable (groceries, rent, and services are often exempt or taxed differently), so treat these as ceilings for planning rather than predictions of your real bill.
State-level rates like the 0% used here come from a single published table, and they leave out several things that change what you actually pay: city and county add-on taxes where Alaska allows them, special district taxes, and product-specific rules (many states tax groceries, clothing, prepared food, or digital goods differently from ordinary merchandise). If you are budgeting a large purchase, such as a vehicle or appliances, confirm the exact combined rate for the delivery address with the Alaska tax agency's own rate lookup, then type that figure into the rate field so the result matches what you will really be charged. For business owners, note that collecting and remitting sales tax has its own registration and filing rules that this calculator does not cover.
Because the pre-filled state rate is zero, the tool at first shows no tax at all: a $100.00 amount in Add Tax mode returns $0.00 in tax and a $100.00 total, and Reverse mode returns the same amount as the pre-tax figure. That result is correct for the state level, but it can be misleading if your purchase happens in a place that charges a local sales tax. The calculator becomes truly useful for Alaska when you enter a local rate in the field. The rate field accepts values from 0 up to 30 percent, and the amount must be greater than zero.
Add: total = amount x (1 + rate). Reverse: pre-tax = total / (1 + rate), tax = total - pre-tax.
Suppose you are pricing a $200.00 purchase and you know the local rate at the store is 5 percent (a made-up figure for illustration, not an actual Alaska rate). In Add Tax mode, the tax is $10.00 and the total is $210.00. If instead you have a receipt total of $210.00 and want the pre-tax price, Reverse mode divides 210 by 1.05 to get $200.00, with $10.00 of tax. If you left the rate at 0, both modes would return the amount unchanged, which is the state-level answer. Testing both the default and a local rate is a quick way to see how much difference local taxation makes to a budget.
Whether tax applies can depend on the location of the sale, the type of goods or service, and the seller. For example, online orders, deliveries between communities, and services may be treated differently from in-store retail purchases. The tool takes a single rate and applies it to the whole amount, and it cannot decide what is taxable. If your situation involves resale, business purchases, or exemptions, consult the relevant tax authority or a qualified tax professional rather than relying on a general estimate.
The most common mistake is assuming that a zero state rate means nothing will be added at checkout. Another is using the Reverse mode incorrectly by subtracting a percentage from the total; dividing by one plus the rate is the correct method, and the tool does it for you. The tool does not include shipping, fees or per-item exemptions, and it displays values rounded to cents, so a receipt may differ by a penny or so. The state-level figure is a snapshot as of the date shown on the page, so verify the current situation with official sources before relying on it for a business or filing decision.
Alaska itself charges no state sales tax, but check whether your specific city/county charges a local sales tax, since that would be the rate that actually applies to you.
Your state's Department of Revenue (or equivalent) publishes the current official rate and any local rate lookups -- always verify there for anything that matters, since rates can change.
At Alaska's 0% state rate the state adds nothing: a $100.00 purchase stays $100.00 before any local tax.
With a 0% state rate the receipt total already equals the pre-tax price, unless a local tax applies.
The pre-filled state-level rate is 0 percent. If a local jurisdiction charges its own sales tax where you are buying, edit the rate field to that local rate to see the tax.
Switch to Reverse mode, enter the total, and set the local rate. The tool divides the total by one plus the rate to give the pre-tax price and the tax.
Yes. The rate field accepts decimals such as 3.5, up to a maximum of 30 percent.
Tax rules come from state and local authorities and can vary by item and location. Use their official guidance for anything important, since this tool applies one rate to the whole amount.
Alaska's statewide sales tax rate is 0%, so there is no state-level sales tax. Across the 51 jurisdictions in this data the average base rate is 5.106%, which puts Alaska 5.106% below the average, tied for 47th highest of 51 jurisdictions (with 4 others). 5 of them charge no state sales tax at all.
Alaska's general minimum wage is $14.00 an hour -- see the Alaska minimum wage calculator for how far that goes after this tax.
| Purchase price | State sales tax | Total at the state rate |
|---|---|---|
| $20 | $0.00 | $20.00 |
| $50 | $0.00 | $50.00 |
| $100 | $0.00 | $100.00 |
| $500 | $0.00 | $500.00 |
| $1,000 | $0.00 | $1,000.00 |
| $10,000 | $0.00 | $10,000.00 |
This is the state rate only. Many cities and counties add their own tax on top, and some items (groceries, clothing, medicine) are taxed differently, so the rate at your register can be higher than the figure above.

Rates are as of September 17, 2026, per the Tax Foundation and U.S. Department of Labor. Confirm the rate for your exact address with your state department of revenue.
