Alaska has no statewide sales tax, which makes it unusual among US states. Instead, individual boroughs and cities set their own local sales tax rates — and they vary widely, from 0% in Anchorage to 5% in Juneau and higher in some small communities. This calculator applies the local rate you enter and supports the per-sale tax cap that many Alaska municipalities use.
How it works
The math is straightforward once you know your local rate:
- Determine the taxable amount. If your municipality caps the taxable portion of a single sale (for example, taxing only the first
$1,000), the calculator uses the lesser of the price and the cap as the taxable base. - Apply the local rate. Multiply the taxable amount by your combined borough-plus-city rate (entered as a percentage).
- Add to the price. The tax is added to the full pre-tax price to give your final total.
The formula is: tax = min(price, cap) × (rate ÷ 100) and total = price + tax. Leave the cap blank or at zero for no cap.
Tips and example
Suppose you buy a $1,500 item in a town with a 6% sales tax and a $1,000 single-sale cap. Only the first $1,000 is taxed, so the tax is $1,000 × 6% = $60, and your total is $1,560 — not $1,590. Without the cap, the tax would be $90.
Because Alaska rates are set locally and can change with municipal ordinances, always confirm the current combined rate and any cap for your specific borough and city before a large purchase. Anchorage and Fairbanks residents pay no sales tax at all.
