Taxpayers who live in states that do not levy a personal income tax still have a path to an itemized deduction for state and local taxes on their federal returns. Under federal law, filers who itemize on Schedule A can elect to deduct general sales taxes paid throughout the year instead of state income taxes, a choice that carries real dollar consequences for households in Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. With the 2025 filing season now open, the mechanics of this election, and the income-driven gap in who actually benefits, deserve a closer look.
Why the Sales-Tax Election Carries Higher Stakes Under the SALT Cap
The federal tax code has long allowed itemizers to deduct state and local taxes. Section 164 of the Internal Revenue Code specifically provides an election: taxpayers may deduct either state and local income taxes or state and local general sales taxes, but not both. For residents of no-income-tax states, there is no income-tax figure to claim, so the sales-tax election is the only way to capture any state-level tax deduction on Schedule A.
That election, however, now operates inside a tighter box. Public Law 115-97, enacted through H.R. 1 of the 115th Congress, imposed a cap on the total state and local tax deduction. Because the cap limits the combined deduction for property taxes and either income or sales taxes, taxpayers who already pay substantial property taxes may find that their sales-tax amount gets partially or fully absorbed by the ceiling. The practical result is that higher-income households, who tend to spend more on taxable goods and who are more likely to itemize in the first place, stand to extract a larger net benefit from the election than lower-income filers whose total SALT claims fall below or near the cap threshold.
Historical data underscore that skew. According to IRS Statistics of Income reports, higher-income itemizers claim a disproportionate share of state and local tax deductions overall, reflecting both larger property tax bills and greater ability to generate deductible sales-tax amounts through discretionary spending. The historical tables show that as income rises, the likelihood of itemizing and the average SALT deduction both climb sharply, suggesting that the sales-tax election mainly amplifies a pattern already embedded in the tax code.
How the IRS Optional Tables Shape the Deduction
Taxpayers claiming the sales-tax deduction face a choice between two calculation methods. They can tally actual receipts for every qualifying purchase made during the year, or they can use the optional sales tax tables the IRS publishes annually. The Schedule A instructions for tax year 2025 detail how those tables work: the agency sets deduction amounts based on filing status, number of dependents, adjusted gross income, and the sales-tax rate in the taxpayer’s state and locality. Filers can also add sales tax paid on certain large purchases, such as motor vehicles and boats, on top of the table amount.
The IRS also maintains an online calculator tool that walks filers through the process. The tool applies the same table methodology but automates the lookup, reducing the chance of manual error. For taxpayers who made unusually large taxable purchases during the year, tracking actual receipts can produce a higher deduction than the tables. But for most filers, the tables offer a simpler route that does not require saving every sales slip.
What Counts as a “General Sales Tax”
A key distinction in the rules narrows which taxes qualify. Only general sales taxes imposed at a uniform rate on the sale of most goods and services in a jurisdiction are eligible. Targeted excise taxes on specific items-such as gasoline, alcohol, or cigarettes-do not count toward the deduction, nor do fees that are not computed as a percentage of sales price. Local add-on sales taxes are included if they are imposed in the same general manner as the state tax.
This definition matters for residents of states that rely heavily on tourism or specific industries. A hotel occupancy tax, for example, may not qualify if it is structured as a special levy on lodging rather than as part of the general sales tax system. Similarly, charges that appear on utility bills or cellphone statements may be partially deductible only to the extent they are truly sales taxes and not regulatory fees or excise taxes. The burden falls on taxpayers to distinguish between these categories when they choose to document actual taxes paid instead of relying on the optional tables.
Who Actually Benefits in No-Income-Tax States
For households in states without an income tax, the sales-tax election is theoretically available to everyone who itemizes. In practice, its value depends on three filters: whether itemizing beats the standard deduction, how close total state and local taxes come to the SALT cap, and how much of a household’s spending falls on taxable goods rather than untaxed services or necessities.
Lower- and middle-income filers often see the standard deduction wipe out any advantage from itemizing, especially if they have modest mortgage interest and property tax payments. Even when they do itemize, their combined property and sales taxes may sit well below the cap, meaning the election simply substitutes one modest deduction for another. By contrast, higher-income homeowners with significant property taxes can quickly reach the SALT ceiling. For them, maximizing the sales-tax component-through large purchases or careful recordkeeping-can preserve a deduction that would otherwise be left on the table.
Planning Ahead for Future Filing Seasons
Taxpayers in no-income-tax states who expect to itemize can take practical steps during the year. Those anticipating major taxable purchases may want to cluster them in a single tax year to boost the deductible amount. Keeping digital copies of invoices for vehicles, boats, and building materials can make it easier to supplement the table-based deduction. At the same time, filers should be realistic about whether their overall itemized deductions will exceed the standard deduction and whether the SALT cap will limit any additional benefit.
As Congress periodically debates the future of the SALT cap and the broader structure of itemized deductions, the sales-tax election remains a niche but consequential provision. For residents of states that forgo an income tax, understanding how that election interacts with property taxes, large purchases, and the cap itself can mean the difference between a merely symbolic deduction and one that meaningfully reduces their federal tax bill.
