Limits on increases
For tax year 2026, value can't rise more than 5% a year. Homesteads are capped at 3% a year. The cap doesn't apply in a year the home is transferred or improvements are added. State Question 847 on the November 3, 2026 ballot would change these caps starting in 2027. It is not law today.

How to apply
File the application with your county assessor.
Deadline
March 15 of the tax year, or within 30 days after a notice of a value increase, whichever is later.

Additional homestead exemption

Who
A head of household who already qualifies for the homestead exemption and whose gross household income last year was $30,000 or less. Income includes Social Security and pensions. It doesn't include gifts, veterans' disability pay or federal COVID stimulus payments. You don't have to be a senior.
What you get
Another $1,000 off your assessed value.
How to apply
File OTC Form 994 with your county assessor.
Deadline
Each year by March 15, or within 30 days after a value increase notice, whichever is later.
If you're late
No lookback was found beyond that deadline.
After that
Every year if you are under 65. If you were 65 or older on March 15 and already qualified, you don't reapply unless your income goes over $30,000. Then you must tell the assessor.

100% disabled veteran homestead exemption

Who
A head of household honorably discharged from the U.S. armed forces or Oklahoma National Guard, rated by the VA as 100% permanently disabled from service, who lives in Oklahoma and qualifies for the regular homestead exemption. The surviving spouse also qualifies. There is no partial-rating exemption.
What you get
The full fair cash value of your homestead, and your household personal property, is exempt from tax. If your 100% rating is effective on or before your application date, it covers the whole year.
How to apply
File with the county assessor where the property is located. Use form 998-B if you bought a replacement homestead in the same year. Form: OTC Form 998.
If you're late
No fixed multi-year lookback was found. If your rating drops below 100%, report it right away or you can lose the homestead exemption in future years.
After that
Continues while you own and live in the home and stay eligible. Ends if title transfers or you no longer qualify.

Senior valuation limitation (senior freeze)

Who
A head of household 65 or older on January 1 who owns and lives in the homestead on January 1. Household income can't be above the HUD estimated median income for your county or metro area. The dollar limit differs by county.
What you get
Your home's fair cash value can't rise above its value in the first year you are approved. It freezes value, not your bill. Rate changes can still change what you pay. State Question 847 would change this freeze starting in 2027 if voters approve it on November 3, 2026.
How to apply
File OTC Form 994 with your county assessor between January 1 and March 15 of the first year you qualify.
Deadline
January 1 through March 15, or within 30 days after a value increase notice if that is later.

Think your value is too high?

Asking for a lower fair cash value

Free review
Yes. File a free written protest with your county assessor on OTC Form 974. The form allows a protest by phone or in person.
Formal appeal
The County Board of Equalization after the assessor's informal decision, then district court.
Deadline
30 calendar days from the date the notice of increase was mailed. If the assessor didn't change your value from last year, file by the first Monday in April. If you miss the window, the assessor's value is final for that year.
Fee
No filing fee is stated on Form 974.
Good to know
Missing the deadline makes the assessor's value final for the year.

A formal appeal reopens your whole value: the board can raise it as well as lower it. Bring recent sales of similar homes.
