The homestead exemption removes a fixed amount from your taxable value, so its dollar savings recur every year. Projected savings grow with the assumed annual tax increase. Real bills also change with reassessments and millage changes.
How to use the homestead exemption calculator
Pick your state to load its exemption structure, enter your home’s value and your local millage rates, and the calculator shows what you would pay with and without the exemption — separating school taxes from county and city taxes, because most states treat those differently.
Choose your state
Texas, Florida and Georgia load their own exemption amounts and assessment ratios. Anywhere else, use custom.
Enter your home’s value
The market or appraised value from your assessment notice, plus the assessment ratio if your state taxes a fraction of it.
Put in your real millage
The single most important step. Presets are statewide averages; your actual school and county rates come from your tax bill.

How the savings are calculated
An exemption comes off the value, not off the bill. So the saving is the exemption multiplied by the rate that applies to it — and because school and non-school layers usually get different exemptions, the calculation runs twice and adds the results.
Worked example — a $400,000 Texas home, 10 school mills and 11 county mills
School side: $400,000 − $140,000 = $260,000 taxable → × 10 ÷ 1,000 = $2,600
County side: no exemption, so $400,000 × 11 ÷ 1,000 = $4,400
Total with homestead $7,000; without it, $400,000 × 21 ÷ 1,000 = $8,400
Annual saving $1,400, an effective rate of 1.75% of market value
That $1,400 is just $140,000 × 10 mills. The house could be worth $900,000 and the saving would be identical — only the exemption size and the rate move it.
What the exemption is worth
How the states compare, why the exemption amount alone tells you nothing, and the assessment cap that often matters more than the exemption itself. The baseline is a $400,000 home at each state’s preset rates.
| State preset | Assessed value | Tax without | Tax with | Annual saving | Effective rate |
|---|---|---|---|---|---|
| Texas, age 65+ | $400,000 | $8,400 | $6,400 | $2,000 | 1.60% |
| Texas, standard | $400,000 | $8,400 | $7,000 | $1,400 | 1.75% |
| Florida | $400,000 | $7,200 | $6,446 | $754 | 1.61% |
| Georgia | $160,000 | $4,480 | $4,424 | $56 | 1.11% |
Georgia’s assessed value is 40% of market, which is why its effective rate looks low despite an 18-mill school levy — and why its $2,000 statewide exemption saves so little. Many Georgia counties add far larger local exemptions that the preset does not know about; edit the fields to match your county and the picture changes completely.
| Exemption | At 6 mills | At 10 mills | At 14 mills | At 18 mills |
|---|---|---|---|---|
| $25,000 | $150 | $250 | $350 | $450 |
| $50,000 | $300 | $500 | $700 | $900 |
| $100,000 | $600 | $1,000 | $1,400 | $1,800 |
| $140,000 | $840 | $1,400 | $1,960 | $2,520 |
| $200,000 | $1,200 | $2,000 | $2,800 | $3,600 |
Read across as well as down. A $50,000 exemption in an 18-mill district beats a $100,000 exemption in a 6-mill one, which is why comparing headline exemption amounts between states tells you almost nothing. Your home’s value does not appear anywhere in this grid — it does not affect the saving.
| Year | Market value at 7% | Capped assessed at 3% | Value shielded | Tax avoided at 18 mills |
|---|---|---|---|---|
| Year 1 | $428,000 | $412,000 | $16,000 | $288 |
| Year 2 | $457,960 | $424,360 | $33,600 | $605 |
| Year 3 | $490,017 | $437,091 | $52,926 | $953 |
| Year 4 | $524,318 | $450,204 | $74,114 | $1,334 |
| Year 5 | $561,021 | $463,710 | $97,311 | $1,752 |
A $400,000 Florida home appreciating 7% a year under the 3% Save Our Homes cap. By year five the cap is worth more than twice the exemption itself, and the gap keeps widening for as long as you stay. Texas caps homestead appraisal growth at 10% and Georgia ties it to inflation where the county did not opt out. The calculator estimates the exemption only — treat the cap as an additional benefit on top.
| State | Exemption structure | Assessment cap |
|---|---|---|
| Texas | $140,000 off school-district value, with an extra $60,000 for homeowners 65 or older or disabled. Counties and cities set their own optional exemptions, often a percentage of value. | 10% a year on homestead appraised value |
| Florida | $25,000 applying to all taxes including school, plus an inflation-adjusted second layer that applies only to non-school taxes on value above $50,000. | 3% a year under Save Our Homes, with portability to a new homestead |
| Georgia | Property assessed at 40% of market value, with a $2,000 standard exemption off county and school maintenance-and-operations value. Local exemptions are frequently much larger. | Tied to inflation under HB 581 in counties that did not opt out |
| Elsewhere | Use the custom preset and enter your own assessment ratio, exemption amounts and millage. Structures vary widely, including percentage-based exemptions and credits applied to the bill rather than the value. | Varies; many states have none |
Rules change with legislative sessions and ballot measures, and local option exemptions vary between neighbouring counties. Confirm current figures with your county appraisal district or property appraiser before relying on any of them.
One house, one price, and a thirty-five-fold spread in what the homestead is worth. None of that comes from the property — it comes from how each state sizes its exemption and which tax layers it aims at.
- The Georgia bar is misleading on purpose — it shows only the $2,000 statewide amount. Local exemptions in many counties are worth vastly more, and the calculator lets you enter them.
- Age and disability exemptions are the biggest single lever — an extra $60,000 in Texas adds $600 a year at 10 mills, and many states have similar additions worth checking.
- Do not compare states on this chart alone — Florida’s low bar sits alongside a 3% assessment cap that quietly outgrows the exemption within a few years of ownership.
Everything the calculator works out
One value and two millage rates give you the full before-and-after, split by tax authority, with a multi-year projection and a report you can file with your tax paperwork.

Built for anyone with a property tax bill
The exemption is one of the few property tax levers a homeowner actually controls, and it is free. The hard part is knowing what it is worth in your specific district before you assume it has been handled.
Confirming the exemption is actually on the account and that the saving showing up on the bill matches what it should be.

Homestead exemption FAQ
The questions homeowners and buyers ask most when a property tax bill or an assessment notice arrives.
It removes a fixed slice of your home’s value from the amount that gets taxed, provided the home is your primary residence. It is not a discount on the bill — it shrinks the value the tax rate is applied to, which is why the same exemption is worth different amounts in different places.
Most states also attach a cap on how fast the assessed value can rise while you live there. Over a long tenure in a rising market, that cap often ends up worth more than the exemption itself.
The exemption amount multiplied by the rate that applies to it. A $140,000 exemption against a 10-mill school rate saves $1,400 a year, because 10 mills is $10 per $1,000 of taxable value.
Notice what is missing: the value of your home. As long as taxable value stays above zero, a $400,000 house and a $900,000 house in the same district save exactly the same dollars from the same exemption.
A mill is one dollar of tax per $1,000 of taxable value, so 10 mills = 1% and 21 mills is 2.1%. Bills are quoted this way because several authorities — school district, county, city, sometimes hospital or water districts — each levy their own millage against the same property.
That layering is why homestead exemptions are rarely a single number. The amount coming off for school taxes is often different from the amount coming off for county and city taxes, and each is multiplied by its own rate.
Because school funding is set at the state level while county and city levies are local, states carve their exemptions into layers that hit each differently.
Texas puts its largest exemption on the school-district portion and leaves county and city exemptions to local option. Florida runs the reverse: a first tier applying to everything including school taxes, plus a second layer applying only to non-school taxes. Getting the split right is the difference between a guess and an estimate.
It limits how much your assessed value can rise in a year while the homestead applies, whatever the market does. Florida’s Save Our Homes caps growth at 3%, Texas caps homestead appraisal growth at 10%, and Georgia ties it to inflation in counties that did not opt out.
In a fast-appreciating market this compounds. A $400,000 Florida home rising 7% a year would be worth about $561,000 after five years but assessed near $464,000 — roughly $97,000 shielded, worth more annually than the exemption. This calculator estimates the exemption only.
Generally you must own the home and occupy it as your primary residence, usually tested as of 1 January of the tax year. Second homes, rentals and investment properties do not qualify, and you can only claim one homestead at a time.
Deadlines vary by state and county — commonly in spring — and several states allow late or retroactive filing for a limited period. Check your county appraisal district or property appraiser for the exact date and form.
No. Filing is free and the form is short. County offices provide it directly, usually online.
New homeowners often receive official-looking letters offering to file the exemption for a fee of $50 or more. These are not from the county, and the service is one you can do yourself in minutes. Any letter asking for payment deserves a call to the county office first.
It does not transfer. The seller’s exemption and any accumulated cap benefit come off, the property is typically reassessed at market value for the new owner, and the buyer must file their own application.
This catches buyers regularly: a listing’s tax figure may reflect years of a previous owner’s capped assessment, and the first full-year bill can be substantially higher. Some states let a seller carry part of their cap benefit to a new homestead — worth asking about before you move.
Estimation Only — Not Tax or Legal Advice: This calculator estimates homestead exemption savings from figures you enter and simplified statewide presets. Exemption amounts, assessment ratios, eligibility rules, filing deadlines and millage rates are set locally, differ between neighbouring counties and cities, and change with legislative sessions and ballot measures; the presets are representative starting points, not a lookup of your jurisdiction. Millage in particular is local and must be taken from your own tax bill. The estimate covers the exemption only — it does not model assessment caps such as Save Our Homes or Texas’s 10% limit, portability of accumulated cap benefits, special district levies, non-ad-valorem assessments, percentage-based or bill-level credits used in some states, senior freezes, deferrals, or the reassessment that typically follows a sale. Whether you qualify depends on ownership, occupancy and residency rules this tool does not test. For planning purposes only; confirm your exemption amounts, deadlines and millage rates with your county appraisal district or property appraiser, and consult a tax professional for advice on your situation.
