The property tax exemptions nobody tells you about, in all 51 jurisdictions
An appeal argues about what your home is worth and might win 8%. An unclaimed exemption is money you are entitled to by statute, granted without argument, and often worth more.
Most people who want a lower property tax bill start by thinking about an appeal. It is the wrong place to start.
An appeal is an argument. You are contesting the county's opinion of what your property is worth, you might be wrong, and in Cook County the median successful appeal reduces assessed value by 8.4%. An exemption is not an argument. It is a reduction the legislature has already granted you if you meet the conditions, and the only question is whether you have applied.
Frequently it is worth more. A Texas school-district homestead exemption removes $100,000 of taxable value. South Carolina's legal-residence classification cuts your assessment ratio from 6% to 4% — a third off the bill — and is granted by filing a form. Neither is available by appealing, and neither happens automatically in most cases.
We maintain a rulebase of 120 exemptions across all 50 states and the District of Columbia, with the statute for each. This article is what it says, organised by the kind of person it helps.
Why people miss them
Three reasons, and they compound.
Most require an application, not an appeal. These are different processes with different forms, different offices and different deadlines. Somebody researching "how do I lower my property taxes" lands in appeal material and never learns the other door exists.
Several must be re-filed after a change. A homestead exemption does not necessarily transfer when a property changes hands, and this catches new-construction buyers constantly — the builder never claimed it, so there is nothing to inherit. Refinancing, adding a spouse to a deed, or moving a property into a trust can all require re-application in some states.
Nothing on your bill says you are eligible and did not claim. A tax bill shows what you were charged. It does not show what you could have been charged. The absence is invisible.
What is out there, by category
| Category | Programmes | Who it is for |
|---|---|---|
| Senior | 44 | Usually 61–65 and over, often with an income ceiling |
| Homestead | 37 | Owner-occupiers. The broadest and most-missed category |
| Veteran | 29 | Service-connected disability ratings, often scaled |
| Income-based relief | 9 | Circuit breakers and hardship programmes |
| Disability | 1 | Standalone; most disability relief sits inside other categories |
The forms relief takes, and why it matters
Not every exemption works the same way, and the mechanism determines how much it is actually worth to you. This is the part that catches people out.
A market-value reduction takes a sum off the value before the assessment ratio is applied. Texas's $100,000 school homestead exemption is this kind. It is the most valuable form, because the reduction is applied before everything else.
An assessed-value reduction takes a sum off after the ratio. Illinois's general homestead exemption removes $8,000 of assessed value — $10,000 in Cook County. Because Illinois assesses at a third outside Cook, $8,000 of assessed value corresponds to roughly $24,000 of market value, so the two forms are not comparable at face value.
A ratio change alters the fraction of value you are taxed on. South Carolina's legal residence classification moves you from 6% to 4%. It is quietly one of the largest reliefs in the country and it applies to owner-occupiers generally, not to a narrow group.
A cap or freeze limits how fast your taxable value can rise. Florida's Save Our Homes caps annual growth at 3%; Texas caps homestead growth at 10%. These are worth nothing in year one and a great deal after a decade in a rising market — which is exactly why they are undervalued by people deciding whether the form is worth filling in.
A credit comes off the tax itself rather than the value. Straightforward, and the easiest to compare directly against a dollar of appeal saving.
A full exemption removes the liability. Most commonly for veterans with a 100% service-connected disability rating, available in many states including Texas, Florida and Michigan.
The ones worth checking first
If you own and live in the home
The general homestead exemption is the single most-missed benefit in the country, because people assume it is automatic. Sometimes it is. Often it is not, and almost never for a property that has just changed hands.
- Texas — school district homestead exemption, $100,000 of market value (Tex. Tax Code § 11.13(b)), plus a 10% annual cap on homestead value growth (§ 23.23).
- Florida — homestead exemption of $50,000 (Fla. Stat. § 196.031), plus the Save Our Homes 3% cap (Fla. Const. art. VII, § 4(d)).
- Illinois — general homestead exemption, $8,000 of assessed value and $10,000 in Cook County (35 ILCS 200/15-175). It appears on a bill as "Owner Occupied". It does not transfer from a builder or previous owner.
- South Carolina — legal residence classification, moving the ratio from 6% to 4% (S.C. Code § 12-43-220(c)).
- Michigan — Principal Residence Exemption, removing school operating millage (MCL 211.7cc).
- California — homeowners' exemption, $7,000 of assessed value (Cal. Rev. & Tax. Code § 218). Small, but it is one form.
If you are 65 or over
Senior relief is the largest category we track, at 44 programmes, and the most likely to carry an income test. Two things are commonly missed: the exemption is usually in addition to the general homestead exemption rather than instead of it, and several must be renewed annually.
- New York — Enhanced STAR removes $84,000 of market value for qualifying seniors (RPTL § 425(4)), against $30,000 for Basic STAR.
- Florida — an additional $50,000 senior exemption on top of the standard homestead (Fla. Stat. § 196.075), where the county or city has adopted it.
- Illinois — senior homestead exemption (35 ILCS 200/15-170) and, separately, the senior assessment freeze (15-172), which locks your assessed value. The freeze is income-tested and must be re-filed; the number of eligible households that let it lapse is substantial.
- Texas — age 65 exemption (§ 11.13(c)), which also brings a school tax ceiling that is separately valuable.
If you are a veteran
Twenty-nine programmes, and the most generous benefits in the entire system sit here — but they are also the most conditional, usually scaled to a service-connected disability rating.
- Texas — a 100% service-connected disabled veteran pays no property tax on the residence homestead (§ 11.131). Partial ratings receive a scaled exemption (§ 11.22).
- Florida — total exemption for total and permanent service-connected disability (§ 196.081), and a percentage discount tied to the rating (§ 196.082).
- California — disabled veterans' exemption up to $175,000 of assessed value (Rev. & Tax. Code § 205.5), far larger than the general homeowners' exemption.
- Michigan — full exemption for qualifying disabled veterans (MCL 211.7b).
- Illinois — standard homestead exemption for veterans with disabilities (35 ILCS 200/15-169), scaled by rating, reaching full exemption at 70%.
Surviving spouses are frequently eligible to continue a veteran's exemption, and this is among the most commonly missed benefits anywhere, because it must be claimed at the worst possible time.
If your income is low relative to your bill
Nine circuit-breaker and hardship programmes. These are means-tested, often administered through the income tax system rather than the assessor, and consequently invisible to anyone looking at property tax material. Michigan's poverty exemption (MCL 211.7u) is decided by the local board of review, which means it is a local application with local discretion — worth asking about directly.
How to check, in about twenty minutes
- Read your most recent tax bill and find the exemption lines. Most bills list what has been applied. If yours shows none, that is the finding.
- Compare against the categories above. Owner-occupier, 65 or over, veteran or surviving spouse of one, disabled, low income relative to the bill.
- Go to your county assessor's site, not the state's. Applications are almost always filed locally even where the exemption is created by state statute.
- Check whether yours needs renewing. Freezes and income-tested benefits usually do. Auto-renewing ones usually stop on a change of ownership.
- Ask about back-claims. Several states allow a missed exemption to be claimed retrospectively for a limited number of years. This is not advertised and it is worth asking.
The one-line version
Before you argue about what your house is worth, check whether the legislature has already decided you should pay less. It takes twenty minutes, it does not depend on winning anything, and in a good number of cases it is worth more than the appeal you were about to spend a weekend on.
