Five States With No Sales Tax
Oregon, Montana, Delaware, New Hampshire, and Alaska have no statewide sales tax. Alaska allows local municipalities to impose sales taxes, so rates vary by city.
Shopping across a state border to avoid sales tax is rarely worth the hassle unless the purchase is very large. A $10,000 purchase at 8% sales tax saves $800 if bought in a no-tax state -- but only if you're already near the border or shopping online.
When to use this
You're budgeting for a big purchase — a laptop at $1,299, furniture at $2,400, or a car at $35,000 — and need to know the actual total with tax. Or you have a receipt showing $86.37 total and want to figure out the pre-tax price for an expense report. This calculator works in both directions: enter a pre-tax price to get the total, or enter a total to reverse-calculate the pre-tax amount.
It's especially useful when comparing prices across states or shopping online. A $1,000 item costs $1,000 in Oregon (no sales tax) but $1,101 in Chicago (10.1% combined rate). For large purchases like appliances, electronics, or vehicles, that difference is significant enough to factor into where you buy. Some people time major purchases around tax-free weekends or shop in neighboring states with lower rates.
Business owners and freelancers use it daily — calculating tax to add on invoices, verifying collected tax against expected amounts, and preparing for sales tax remittance. If you sell anything in the US, you need to know these numbers.
Good to know
The forward formula: Tax = Price x Rate / 100. Total = Price + Tax. The reverse formula: Pre-Tax Price = Total / (1 + Rate / 100). A $50 item at 8.25% tax: Tax = $4.13, Total = $54.13. Working backwards from $54.13: Pre-Tax = $54.13 / 1.0825 = $50.00.
Sales tax rates vary wildly by location. Five states have no state sales tax: Oregon, Montana, Delaware, New Hampshire, and Alaska (though some Alaska municipalities charge local tax). The highest combined state + local rates are in parts of Louisiana, Tennessee, Arkansas, Washington, and Alabama, where rates can exceed 10%. Your effective rate depends on your specific city and county.
Not everything is taxed equally. Most states exempt groceries (food for home consumption) from sales tax or tax them at a reduced rate. Many exempt prescription medications. Some states exempt clothing under a threshold (e.g., New York exempts clothing items under $110). Rules vary significantly — check your state's specific exemptions.
Online purchases are taxed based on where you live, not where the seller is. Since the 2018 South Dakota v. Wayfair Supreme Court decision, states can require out-of-state sellers to collect sales tax. Most major online retailers now charge your local rate automatically. If they don't, you technically owe "use tax" on your state tax return — though compliance on small purchases is low.
