Which State Has the Highest Sales Tax?

The ranking that matters: combined state + average local

State rates alone mislead — Alabama's 4% state rate sounds gentle until its 5.44% average local layer lands on top. The honest measure is the combined average (population-weighted local rates, per the Tax Foundation Midyear 2026 convention¹), and the 2026 top ten looks like this:

The pattern: every top-five state pairs a moderate state rate with a heavy local layer. Louisiana's parishes, Alabama's cities, and Oklahoma's municipal budgets do the lifting — the mechanics explained in sales tax by county. The full sortable table for all 50 states lives on sales tax by state.

The other ranking: highest state-level rates

Note the two clean cases: Indiana and Rhode Island allow no local sales taxes, so their 7% is the exact rate at every address in the state — the same property that makes ZIP-level lookup safe there. California's 7.25% headline, by contrast, is just the floor: district taxes carry cities like Oakland to 10.75%.

Beyond the averages: where checkout rates peak

Averages hide the extremes. The single highest checkout rates in America are in small Louisiana jurisdictions — Monroe runs above 13%, and special districts within Baton Rouge reach 12.5% — while among major cities the top is Oakland's 10.75%, then Seattle's 10.55%. That city-level ranking, verified August 2026, is its own guide: the US cities with the highest sales tax.

How this ranking is built

Rankings of "highest sales tax" disagree with each other because they measure different things. This one is explicit about its method so you can tell whether it answers your question:

• Metric: the state statutory rate plus the population-weighted average local rate — not the maximum local rate. A state where one small town levies an outlier does not move up the table; a state where most residents pay a high local rate does.
• Scope: the 50 states. Washington, DC is excluded from the ranking because it is a single district rather than a state, which would otherwise distort like-for-like comparison.
• Excluded: special district rates that apply to a defined area rather than a jurisdiction — stadium districts, tourism improvement districts, and transit surcharges. Those push individual checkout rates above the figures here, which is what the city ranking measures instead.
• Also excluded: selective excise taxes on fuel, alcohol, tobacco, lodging, and prepared food. Those are real costs and they are not general sales tax.
• Source and currency: rates are drawn from our maintained rate dataset, with each state's revenue department attached as the underlying authority — see tax data sources for the verification status of each dataset, and sales tax by state for the full lookup table.

Why these five states are at the top

The interesting part of the ranking is that the five leaders arrive there by completely different routes — which is why "high sales tax state" is a poor predictor of anything on its own.

• Louisiana (10.13%) — the local layer exceeds the state layer. The state rate of 5% is unremarkable; average parish and local rates of about 5.13% are the highest in the country and are what put Louisiana first. Parishes have historically administered and collected their own tax, which produced both the high rates and a compliance burden the state has been working to centralise.
• Tennessee (9.61%) — a high state rate substituting for income tax. Tennessee levies no broad individual income tax, and its 7% state rate is among the highest state-level rates in the country. Groceries are taxed, though at a reduced rate, so the burden reaches everyday spending rather than sitting only on discretionary items.
• Washington (9.57%) — no income tax, heavy local option. Like Tennessee, Washington funds itself without a broad income tax; unlike Tennessee, it exempts groceries, so the effective burden on a household depends heavily on what share of spending is food. Local rates average over 3%, and the Seattle metro runs well above.
• Arkansas (9.48%) — high on paper, capped in practice for big purchases. Arkansas pairs a 6.5% state rate with local rates near 3%, but local tax applies only to the first $2,500 of a single qualifying transaction. On large purchases the effective rate falls well below the headline, which no ranking of average rates can show.
• Alabama (9.46%) — the most extreme local-versus-state split. A 4% state rate, among the lowest in the nation, sits under an average local rate of about 5.46% spread across more than 400 local taxing jurisdictions. Groceries are taxed at a reduced 2% state rate since September 2025, with local tax still applying on top.

What a high combined rate actually costs

The gap between the top and the bottom of the table is larger than it looks in percentage points. On $40,000 of annual taxable household spending, the difference between Louisiana at 10.13% and Wyoming at 5.39% is $1,896 a year — a meaningful figure for a household, and one that compounds over a decade of residence.

For a business the arithmetic works differently, because sales tax is collected rather than borne. What a high rate changes for a seller is competitive and operational: price sensitivity at the shelf near a lower-rate border, the size of the trust liability sitting in the bank account between collection and remittance, and the exposure created by getting a rate wrong. A 1% error on $2,000,000 of taxable sales is $20,000 of assessment before interest — and in the high-local states at the top of this table, the local layer is where rate errors concentrate, because it is the layer that changes at boundaries.

The states that fund themselves this way generally take less elsewhere. Tennessee and Washington run no broad income tax; Louisiana and Alabama keep property taxes among the nation's lowest. A ranking of one tax measures one leg of a three-legged stool.

The honest caveats

• Baskets matter. Louisiana exempts groceries at the state level, Tennessee taxes them at a reduced 4%, Washington exempts food, Minnesota exempts food and clothing — the exemption map reshuffles real burdens.
• High sales tax usually buys something. Tennessee and Washington fund government without a broad income tax; Louisiana and Alabama keep property taxes among the nation's lowest. Rankings measure one leg of the stool.
• Rates moved recently. Louisiana's lead widened with its January 2025 increase, and 2026 brought waves in Washington and Illinois — tracked change by change in sales tax changes in 2026.
