US sales tax rate history — what changed and when
State-level sales tax rate changes for all 50 states and DC since 2015 — with effective dates, prior rates, and the legislative reason behind each change. Most states have kept their rate stable for a decade or more.

State statutory rates only. Local and county add-ons are not reflected — see current combined rates by state for what consumers actually pay. Rate changes recorded are to the state-level statutory rate set by the legislature. Effective dates are the date the new rate took legal effect. New Mexico's rate refers to its Gross Receipts Tax, which functions similarly to a sales tax but is technically levied on sellers.

Understanding the US sales tax rate record
The formula behind every calculation
Whatever the rate and whatever the era, the sales tax formula is always the same: Tax = Price × (Rate ÷ 100). A $200 purchase in North Carolina in 2015 incurred $11.50 tax at the then-rate of 5.75%. The same purchase today incurs $9.50 at the current 4.75% rate — a meaningful difference on larger buys. To find the tax-inclusive total directly: Total = Price × (1 + Rate ÷ 100). And to reverse-calculate the pre-tax price from a tax-included receipt, use: Pre-tax = Total ÷ (1 + Rate ÷ 100). The sales tax calculator handles all three directions instantly for any amount and any rate, historical or current.
The big picture: only seven states changed their rate since 2015
Of 50 states plus DC, only seven changed their state-level statutory sales tax rate between 2015 and 2026. That is 14% of all jurisdictions in more than a decade. The remaining 44 states and DC either have no sales tax (five states) or have held their rate steady throughout. This extraordinary stability reflects the political difficulty of changing a tax that consumers experience at every transaction. Governors and legislators who raise it face angry voters; those who cut it must find replacement revenue or reduce services. The result is a system that moves very slowly — most rates have held for well over a decade, and several (Florida's 6%, Michigan's 6%, Texas's 6.25%) have not changed since the 1980s or 1990s.
North Carolina's historic cut
The largest single state sales tax rate reduction in the period — and arguably in modern US history — was North Carolina's 5.75% to 4.75% cut on March 1, 2016. A full percentage point. The cut was part of a sweeping 2015 tax reform package passed by the Republican-controlled legislature, which simultaneously broadened the tax base to cover more services (reducing the revenue impact), lowered personal income tax rates, and restructured corporate taxes. The net effect on consumers was significant: on a $500 appliance, the change saves $5.00 in state sales tax. For the automotive and housing sectors, where sales tax on individual transactions can run hundreds of dollars, the difference is material. North Carolina's rate had previously been at 5.75% since 2011.
South Dakota, Wayfair, and the internet tax revolution
South Dakota raised its state sales tax from 4% to 4.5% in November 2016 — but the rate change itself was almost a footnote to the larger significance of the legislation. Senate Bill 106, the same law that enacted the rate increase, also established an economic nexus standard: out-of-state sellers making more than $100,000 in annual sales or 200 or more transactions in South Dakota were required to collect and remit sales tax. This provision was challenged in court, eventually reaching the US Supreme Court, which upheld it in South Dakota v. Wayfair, Inc. (2018). Every state with a sales tax now has similar economic nexus rules, transforming how online retailers handle tax collection across the country. The current combined rates by state now apply to virtually all online purchases nationwide.
Louisiana's back-and-forth
Louisiana had the most turbulent rate history of any state in the period. Its base rate stood at 4% for many years. A severe budget shortfall in 2016 prompted the legislature to enact a temporary emergency increase to 5%, effective April 1, 2016. The increase was always framed as temporary — the enabling legislation set a sunset date — but it gave legislators several years to negotiate a permanent solution. When the temporary measure expired in June 2018, the state did not revert to the original 4%. Instead, it enacted a permanent rate of 4.45%, representing a compromise between the pre-crisis rate and the emergency level. This 4.45% rate has been stable since July 2018. Louisiana is unusual in that most states either cut or raise their rate once — Louisiana effectively did both in a two-year window.
New Jersey's two-step reduction
New Jersey cut its sales tax as part of an unusual cross-partisan budget deal in 2016. The state had carried a 7% rate for years — among the higher state rates — and the cut was linked to a significant increase in the state's fuel tax, which had been low by national standards. The sales tax dropped to 6.875% on January 1, 2017, and then to 6.625% on January 1, 2018. The phased approach was deliberate: it gave state revenue forecasters time to confirm that the fuel tax increase was generating sufficient replacement revenue before the second sales tax cut took effect. At 6.625%, New Jersey's rate is now below the national average for states that have a sales tax.
Why rates stay frozen for decades
Political science research on tax policy consistently finds that consumption taxes are among the hardest to change once set. Unlike income taxes, which rise and fall automatically with economic cycles, sales taxes require affirmative legislative votes to move in either direction. States that relied heavily on sales tax revenue during economic downturns (2008–2009, 2020) generally chose to raise other taxes or cut spending rather than raise the visible sales tax. States considering cuts, meanwhile, face pressure from credit rating agencies and school funding advocates who warn about structural deficits. The five states with no sales tax at all — Oregon, Montana, New Hampshire, Delaware, and Alaska — have maintained that status for generations; none has come close to enacting one despite various proposals. This stability makes the changes that do occur genuinely newsworthy and worth tracking. For sellers pricing products or managing tax obligations across states, understanding not just current rates but their history matters: a rate that has been stable for 30 years is unlikely to change next quarter, while a rate that changed twice in two years warrants closer monitoring. The discount + tax calculator is useful for modelling how different combined rates affect the customer's final price across states.
Grocery exemptions and reduced rates: the invisible changes
Not every meaningful sales tax change shows up as a headline rate change. Several states modified their grocery exemptions or reduced rates during this period without touching the standard rate. Illinois, for example, which applies a 1% rate to food and medicine (vs. 6.25% for general goods), debated and rejected proposals to apply the standard rate to groceries. Kansas, whose 2015 rate increase applied to everything including groceries, subsequently enacted a grocery exemption in 2022 — a significant tax cut for low-income households, achieved without changing the headline 6.5% rate. Understanding the full tax burden on a purchase in any state requires knowing both the rate and what is exempt. For VAT systems in Europe, which similarly have reduced and zero rates for essential goods, the VAT calculator covers the major European countries with their current standard and reduced rates.
How this data is compiled and verified
The history table on this page draws from state revenue department announcements, Tax Foundation annual reports on state and local sales tax rates, and National Conference of State Legislatures (NCSL) tax data. For each state, the "last changed" date refers to the effective date of the most recent change to the statutory state-level rate — the date on which the new rate legally took effect for taxable transactions. Where no confirmed change has occurred since 2015, the state is marked as stable. "Prior rate" refers to the rate immediately before the most recent change; for states with multiple changes in the period (Louisiana, New Jersey), the prior rate shown is the one immediately before the current rate. All rates are state statutory rates; local, county, and special district add-ons are not included in this table. For total combined rates — which include local add-ons and are what consumers typically pay — see the sales tax rates by state reference page.
Frequently asked questions
Seven states changed their state-level rate: Kansas (6.3%→6.5%, Jul 2015), North Carolina (5.75%→4.75%, Mar 2016), South Dakota (4%→4.5%, Nov 2016), Louisiana (4%→5% in 2016, then settled at 4.45% in Jul 2018), New Jersey (7%→6.625% over two years by Jan 2018), Utah (5.95%→6.1%, Jan 2019), and New Mexico (gross receipts tax reduced from 5.125% to ~4.875% by Jul 2023). All other states kept their rate unchanged throughout this period.
North Carolina dropped its rate from 5.75% to 4.75% on March 1, 2016 — a full percentage point cut — as part of a sweeping 2015 tax reform package. The legislature offset the revenue loss by broadening the tax base to cover more services and restructuring income and corporate taxes. It remains the largest single state sales tax rate cut in recent US history.
South Dakota raised from 4% to 4.5% in November 2016 under Senate Bill 106 — the same law that created an economic nexus standard for out-of-state sellers. That nexus provision was challenged in court and upheld by the US Supreme Court in South Dakota v. Wayfair (2018), fundamentally changing how all states collect online sales tax.
Louisiana had the most volatile rate in the period. The state's base was 4%, but a budget shortfall prompted a temporary emergency increase to 5% (April 2016). When the temporary measure expired in June 2018, the state negotiated a permanent rate of 4.45% — higher than the original 4% but lower than the emergency 5%. That rate has held since July 2018.
Changing a sales tax rate requires a legislative vote, which is politically costly in both directions. Raising it means explaining a tax hike to voters; cutting it means finding replacement revenue or reducing services. Most state rates have been stable for over a decade — Florida's 6% has not changed since 1988, Michigan's since 1994, Texas's since 1990. Political inertia acts as a powerful stabiliser.
South Dakota v. Wayfair (2018) required out-of-state online sellers to collect sales tax even without a physical presence in a state. This dramatically expanded the tax base — giving states additional revenue from online commerce — which reduced pressure on several states to raise their statutory rates. The law that established this nexus standard was enacted alongside South Dakota's 2016 rate increase.
Technically no. New Mexico's Gross Receipts Tax (GRT) is levied on sellers rather than buyers. However, sellers typically pass the cost on, so the practical effect for consumers is similar to a sales tax. The GRT was 5.125% for many years before a phased legislative reduction brought it down to approximately 4.875% by July 2023. The key structural difference is that the GRT applies to business receipts, not just final consumer transactions.
The formula is the same regardless of era: Tax = Price × (Rate ÷ 100). A $100 purchase in New Jersey in 2016 incurred $7.00 tax (rate was 7%); today the same purchase incurs $6.625 (rate is 6.625%). To reverse-calculate the pre-tax price: Pre-tax = Total ÷ (1 + Rate ÷ 100). The sales tax calculator handles all three directions for any rate, current or historical.
