State tax exemptions are dollar amounts and categories of income that your state removes from your taxable income before calculating what you owe. They differ from credits, which subtract from the final tax bill; an exemption shrinks the base the tax rate is applied to. Two kinds matter most: per-person exemptions for you and your dependents, and exemptions for specific types of income like Social Security or municipal bond interest. What you can claim depends heavily on where you live.
Why State Rules Don’t Match Your Federal Return
The Tax Cuts and Jobs Act of 2017 zeroed out personal exemptions on federal returns, and the One, Big, Beautiful Bill signed into law in 2025 made that permanent. For 2026, the federal personal exemption stays at zero.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments from the One, Big, Beautiful Bill You won’t subtract anything on Form 1040 for yourself, your spouse, or your dependents.
Many states decoupled from that change and still allow personal exemptions on the state return. Amounts range from around $1,000 per person in some states to several thousand in others. A few states converted their exemptions into small per-person credits instead. Roughly ten states have no individual income tax, so the question doesn’t apply to their residents at all.
This is where filers lose money. If you’ve been carrying your federal habits into your state return and skipping the exemption lines, you may have been overpaying for years.
Personal and Dependent Exemptions
In states that keep them, personal exemptions let you subtract a flat amount for yourself, your spouse on a joint return, and each qualifying dependent. State definitions of a dependent generally track federal rules under Internal Revenue Code Section 152, which recognizes two categories: qualifying children and qualifying relatives.
A qualifying child must be your son, daughter, stepchild, foster child, sibling, or a descendant of any of them; must be under 19 at year-end, under 24 if a full-time student, or any age if permanently and totally disabled; must live with you more than half the year; and cannot have provided more than half of their own support.
A qualifying relative is broader and can include parents, siblings, or other household members. The key difference is a gross income test: for 2026, a qualifying relative generally must have gross income under $5,050 and receive more than half of their financial support from you.2Internal Revenue Service. Dependents That threshold adjusts for inflation, so check the current figure before you file.
Claiming a dependent who doesn’t qualify, or claiming one that another taxpayer also claims, can get your return rejected or trigger penalties. Confirm every test before you list someone on your return.
Income Categories States Exempt
Beyond per-person amounts, states exempt whole types of income. These don’t happen automatically. You have to identify the exempt income and report it on the right line, or you’ll pay tax you don’t owe.
Municipal Bond Interest
Interest on state and local government bonds is excluded from federal gross income under 26 U.S.C. ยง 103.3Office of the Law Revision Counsel. 26 U.S. Code 103 – Interest on State and Local Bonds Most states extend the exclusion to bonds issued within their own borders, meaning a home-state muni is typically free of both federal and state tax.
Out-of-state bonds are the trap. Your home state will usually tax interest from a bond issued by another state, even though the federal government won’t. Investors in national municipal bond funds often find a slice of their “tax-free” interest landing on the state return, and in high-tax states the state bite can wipe out much of the yield advantage.
Social Security Benefits
The great majority of states do not tax Social Security retirement benefits. As of 2026, only eight states tax any portion of Social Security income, and most of those provide exemptions or credits that shield lower-income retirees. If you live in one of the roughly 40 states that fully exempt Social Security, none of it belongs in your state taxable income.
Military Retirement Pay and Pensions
More than half of the states with an income tax fully exempt military retirement pay. Many of the rest offer a partial exclusion, often the first $10,000 to $20,000 or so of annual military retirement income depending on the retiree’s age.
Private-sector pensions get less consistent treatment. Some states fully exempt government and public-employee pensions but tax private retirement income normally. Others offer a general retirement income exclusion that applies regardless of source but caps the amount.
529 Plan Distributions
Earnings withdrawn from a 529 plan for qualified education expenses aren’t subject to federal income tax.4Internal Revenue Service. 529 Plans: Questions and Answers Every state that levies a personal income tax also exempts qualified distributions from state tax. Some states also offer a deduction or credit for contributions, though several limit that benefit to contributions made to the state’s own plan. Qualified expenses include tuition, fees, books, room and board at eligible institutions, and up to $10,000 per year in elementary or secondary school tuition.
Extra Exemptions for Seniors, Blind, and Disabled Filers
Many states stack additional exemptions or deductions on top of the standard personal amount for filers who are 65 or older, blind, or permanently disabled. These can push your effective filing threshold high enough that you owe nothing.
Federally, filers 65 and older already receive an additional standard deduction, and the One, Big, Beautiful Bill added a new enhanced deduction for seniors for 2026.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments from the One, Big, Beautiful Bill Many states mirror some version of the age-based add-on. Amounts and cutoffs vary; some states use 65, others 62 or 60 for particular categories.
Legally blind filers qualify for additional amounts in most states that follow the federal model, and you’ll generally need a certified statement from an ophthalmologist or optometrist to claim it.5Internal Revenue Service. Publication 501 (2025), Dependents, Standard Deduction, and Filing Information Permanent disability status is usually documented through a Social Security Administration award letter or a state-level medical certification.
Stacked together, these amounts matter. A married couple both over 65 can shelter tens of thousands of dollars of retirement income between exemption and deduction add-ons. If you’ve been on a fixed income and never claimed them, prior-year returns are worth a look.
How to Claim State Tax Exemptions
Exemptions don’t apply on their own. You claim them by completing the right lines and schedules on your state return, and that starts with having the paperwork ready.
Documents to Have on Hand
Every dependent needs a Social Security number or Individual Taxpayer Identification Number.6Internal Revenue Service. Individual Taxpayer Identification Number (ITIN) For age-based exemptions, keep proof of date of birth. For blindness or disability, have the physician’s statement or SSA award letter.
For exempt income, pull your year-end forms. A 1099-INT reports interest, including muni bond interest that may be state-exempt. A 1099-R covers pension and retirement distributions where a full or partial exemption might apply. A 1099-SSA shows Social Security income. Without these, you’re guessing at figures that need to be exact.
Filling Out the Return
Most state returns start from your federal adjusted gross income and then apply state-specific additions and subtractions. Exemptions for specific income types live in the subtraction step. Every state has its own schedule or worksheet for this, and the form names differ, but the idea is the same: list the income the state doesn’t tax, subtract it from the federal starting figure, and arrive at your state taxable income.
Tax software handles most of this if you answer the interview questions correctly. If you file manually or want to check the software’s output, read the subtraction schedule line by line. That’s where muni interest, Social Security, military retirement, and similar items get pulled out. Missing a line here is the single most common way people overpay state tax.
If You Moved During the Year
Move to a new state mid-year and you’ll usually file as a part-year resident in both. Most states prorate personal exemptions and income-based exemptions according to how long you lived there or how much of your income you earned as a resident. You’ll complete a separate part-year schedule that allocates income between the two states. When the two states have very different exemption structures, this is a place where professional help often pays for itself.
Fixing a Return That Missed an Exemption
If you realize an exemption was left off, you can amend. Federally, you generally have three years from the date you filed the original return or two years from the date you paid the tax, whichever is later.7Internal Revenue Service. Time You Can Claim a Credit or Refund Most states use a similar window, though deadlines can shift by a few months.
Amending pays off when the missed item is substantial: Social Security income taxed in a state that exempts it, or a senior add-on skipped for several years running. Each year is a separate amended return, so start with the oldest eligible year, since that one falls out of the window first.
Penalties for Claiming Exemptions You Don’t Qualify For
Claiming an exemption you aren’t entitled to has real cost. States assess interest on the underpayment from the original due date, and those rates tend to run higher than most consumer debt.
The size of the penalty turns on intent. A negligent error, such as claiming a dependent who actually provided more than half their own support, typically draws a penalty of around 20 percent of the underpayment. Deliberate fraud, like fabricating a dependent, can reach 75 percent plus possible criminal exposure. States generally follow the federal framework on this distinction, though exact percentages vary. Keep the supporting paperwork, including birth certificates, SSA letters, physician statements, and 1099 forms, for at least four years after filing in case the state asks.
