The most reliable ways to lower your state taxes are the ones built into your paycheck and your state’s own tax form: put more into pre-tax retirement and health accounts, claim every state credit you qualify for, use 529 or ABLE contributions where your state rewards them, and, if your situation fits, take advantage of pass-through entity elections or in-state municipal bond exemptions. The federal return gets most of the attention, but because nearly every state starts its calculation with your federal adjusted gross income, the same moves that shrink your federal bill usually shrink your state bill too — and states layer on deductions, subtractions, and credits the IRS never sees.
Contribute Pre-Tax Wherever You Can
Pre-tax contributions are the easiest lever because they lower your federal AGI, and most states build their taxable income from that number. Money you put into a traditional 401(k), 403(b), or similar employer plan comes off your gross pay before your state sees it. For 2026, the elective deferral limit is $24,500, up from $23,500.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
Traditional IRA contributions work the same way when you qualify for the deduction. The 2026 IRA cap is $7,500, or $8,600 at 50 and older.2Internal Revenue Service. Retirement Topics – IRA Contribution Limits
Health Savings Accounts belong in the same conversation. If you have a high-deductible health plan, HSA contributions reduce your federal AGI, and nearly every state follows. The 2026 limits are $4,400 for self-only coverage and $8,750 for family coverage.3Internal Revenue Service. Notice 2026-05 – HSA Inflation Adjusted Amounts The balance grows tax-free and comes out tax-free for medical expenses. California and New Jersey do not recognize the HSA deduction at the state level, so if you live in one of those states the federal savings is real but the state savings is not.
Pick the Right Deduction and Watch for State-Only Subtractions
Most states let you choose between a standard deduction and itemizing, and the amounts and rules rarely match the federal return exactly. Some states don’t allow itemized deductions at all. Others tie your state choice to whatever you did federally.
The bigger opportunity is often in the state adjustments. States routinely add back federal deductions or, more usefully, allow subtractions the IRS doesn’t. Several states let retirees subtract pension income or Social Security benefits that are fully taxable on the federal return. Those subtractions can be worth thousands of dollars a year to a retiree who knows to claim them.
The practical step: open your state’s instruction booklet before you file, compare your itemizable expenses (mortgage interest, property taxes, charitable contributions) against your state’s standard deduction, and take whichever is larger. Then scan the subtraction schedule line by line. That’s where the state-only savings live.
State Credits Are Worth More Than Deductions
A deduction reduces the income that gets taxed. A credit reduces the tax itself, dollar for dollar. The credits below are the ones people most often leave on the table.
State Earned Income Tax Credit
More than 30 states plus the District of Columbia offer their own version of the Earned Income Tax Credit, usually calculated as a percentage of the federal credit.4Internal Revenue Service. Earned Income Tax Credit (EITC) If you qualify federally, check your state. Where the state version is refundable, it can produce a payment even when your state tax is already zero.
Child and Dependent Care Credit
If you paid for childcare or care for a disabled dependent so you could work, most states with an income tax offer a credit that mirrors the federal one. You’ll need the care provider’s name, address, and taxpayer identification number, plus your total costs for the year.5Internal Revenue Service. Child and Dependent Care Credit FAQs The federal claim runs through Form 2441, and states with parallel credits usually pull the same numbers.6Internal Revenue Service. About Form 2441, Child and Dependent Care Expenses
Clean Energy Credits
A growing number of states offer credits for residential solar, geothermal heat pumps, battery storage, and similar upgrades. These stack on top of the federal residential clean energy credit, so the same installation can cut both bills in the same year.7Internal Revenue Service. Residential Clean Energy Credit Keep purchase receipts, and check whether your state requires a certified energy audit.
Property Tax Circuit Breaker
Roughly half the states offer a “circuit breaker” credit that caps property taxes at a percentage of household income and refunds the difference through the income tax return. Programs typically target seniors, people with disabilities, and lower-income households, and many extend to renters on the theory that property taxes are baked into rent. Income limits and claim forms are on your state revenue department’s site.
529 and ABLE Contributions
Contributions to a 529 college savings plan are not deductible federally, but more than 30 states offer a deduction or credit for what you put in during the year.8Internal Revenue Service. 529 Plans: Questions and Answers Earnings grow federally tax-free when used for qualified education expenses.9Office of the Law Revision Counsel. 26 USC 529 – Qualified Tuition Programs The federal gift tax exclusion allows up to $19,000 per beneficiary in 2026, or up to $95,000 in a single year using five-year averaging.10Internal Revenue Service. What’s New – Estate and Gift Tax State deduction caps are usually much lower than that, so check your state’s specific limit before assuming a large contribution will produce a proportional state deduction.
One trap: if you pull money out for anything other than qualified education expenses, most states will “recapture” the deduction you previously claimed, adding it back to your taxable income in the year of the non-qualified withdrawal. Some tack on an additional penalty. The same recapture risk can apply when you roll funds to another state’s plan. Read the plan disclosure before moving money.
ABLE accounts work along the same lines for people with disabilities. Contributions grow tax-free when used for qualified disability expenses, the account doesn’t count against most public assistance eligibility, and the 2026 annual contribution limit matches the gift tax exclusion at $19,000, with an additional amount allowed for employed beneficiaries.11Internal Revenue Service. ABLE Savings Accounts and Other Tax Benefits for Persons With Disabilities Many states that offer 529 deductions extend similar treatment to ABLE contributions.
In-State Municipal Bond Interest
Interest from municipal bonds issued by state or local governments is generally exempt from federal income tax. If the issuer is inside your own state, the interest is usually exempt from your state’s income tax as well. That double exemption makes in-state munis particularly useful for investors in higher brackets.
Your brokerage reports tax-exempt interest in Box 8 of Form 1099-INT.12Internal Revenue Service. Instructions for Forms 1099-INT and 1099-OID You then subtract in-state amounts on the appropriate line of your state return. Track which bonds are in-state and which are not, because out-of-state municipal interest is often still taxed by your state even when the federal exemption applies. Private activity bonds, which fund things like airports and housing rather than general government operations, are treated differently in some states and are a preference item for the federal alternative minimum tax.
SALT and the Pass-Through Entity Election
The federal deduction for state and local taxes affects the real cost of your state bill, because when you deduct state income tax on Schedule A the federal government picks up part of it. Starting in 2025, the SALT cap rose to $40,000 for most filers ($20,000 for married filing separately), up from the $10,000 cap in place since 2018.13Internal Revenue Service. How to Update Withholding to Account for Tax Law Changes for 2025 The cap is scheduled to adjust for inflation through 2029 before reverting to $10,000 in 2030.
For owners of S corporations, partnerships, and LLCs, the pass-through entity tax election is one of the most valuable state tax strategies currently available. More than 35 states now let the entity pay state income tax at the entity level rather than passing it to individual owners. The entity deducts the payment on its federal return with no cap, and owners receive a credit on their state returns for the tax the entity already paid. The net result is a full federal deduction for state tax on business income. Election deadlines and payment schedules vary by state, and the mechanics benefit from planning before year-end rather than at filing time.
Multi-State Work
Living in one state and working in another gives both states a claim on your wages. How it plays out depends on the agreement between them.
Reciprocity Agreements
About 16 states and the District of Columbia participate in roughly 30 reciprocity agreements, mostly clustered in the Mid-Atlantic and Midwest. Under these agreements you only owe tax to your home state, and you file an exemption form with your employer so they withhold for your state of residence instead of the state where the office sits.
Without a reciprocity agreement, you generally file a nonresident return where you work and a resident return where you live. Your home state usually allows a credit for taxes paid to the other state, capped at the lesser of what you actually paid or what your home state would have charged on the same income. In practice you end up paying whichever rate is higher.
Convenience of the Employer
Remote workers face an added wrinkle in about eight states that apply some form of the “convenience of the employer” rule. If your employer is based in one of those states, that state can tax your wages based on the office’s location rather than yours, even when you never work there in person. If your remote arrangement crosses state lines, confirm whether your employer’s state uses this rule before you assume your home state’s rate is what you owe.
Changing Your State of Residence
Moving to a state with no income tax is the most decisive way to reduce your state tax bill. Nine states currently impose no individual income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Renting a place or buying a second home there is not enough. You have to change your legal domicile, and revenue departments in the state you’re leaving are aggressive about testing whether the change is real.
The center-of-your-life analysis looks at where you vote, where your driver’s license is issued, where your vehicles are registered, where your bank accounts sit, where you receive mail, where your professional licenses are active, and where you actually spend your time. Many states also apply a 183-day statutory residency test: spend more than half the year in the state and you’re a resident regardless of what you call home.14Internal Revenue Service. Substantial Presence Test Flight records, credit card receipts, and cell phone data are the usual evidence when a former state challenges the move.
Some states also reach back for income earned before the move. Deferred compensation, stock options that vested during your residency years, and gains on real estate sold near the time of the move can all be taxed by your former state. If you have significant deferred income or appreciated assets, the timing of the move matters as much as the destination.
Mistakes That Erase the Savings
- Missing the calendar-year deadline for 529 or retirement contributions. A contribution made on January 2 doesn’t count for the prior year’s state deduction.
- Skipping a nonresident return when you earned income in another state. Penalties and interest compound monthly, and the obligation doesn’t disappear.
- Overwithholding and treating a big refund as good news. A consistent large state refund means you’ve been lending the state money at zero interest. Adjust your state withholding.
- Assuming your state follows every federal rule. States add back and subtract items in ways that surprise people every year. Read the state instructions, not just the federal ones.
State tax rules shift each year — new credits appear, deduction amounts adjust for inflation, reciprocity agreements sometimes lapse. Before you file, spend 30 minutes on your state revenue department’s website looking specifically for new subtractions or credits added since last year. The savings are real, and they go to whoever bothers to read the instructions.
