Property Tax Exemption Program · 2027 Update
Property Tax Exemption for Senior Citizens and People with Disabilities
In 2026 the state legislature expanded this program by increasing the income thresholds in each county, adding a standard deduction option, and expanding the taxes exempt by the program beginning in tax year 2027. Let's see if you may qualify.
THIS IS A SCREENING TOOL — NOT AN OFFICIAL DETERMINATION.
Only your county assessor can officially determine your eligibility after reviewing your completed application and supporting documents.
Already receiving the exemption?
You do NOT need to reapply. Under the new law, your county assessor will automatically review your income and place you at the correct exemption level. Any change will appear on your 2027 property tax statement. Most current participants will be moved to a better level of exemption.
Your county
Which county is the residence in?
Each county has its own income thresholds, based on that county's median household income.
Age or disability
Do you meet the age or disability requirement?
By December 31 of the assessment year (December 31, 2026 for taxes due in 2027), at least one of the following must be true.
Ownership & occupancy
Do you own and occupy the residence as your primary home?
You must be a registered owner by December 31 of the assessment year, and must occupy the residence for more than six months during that year. A residence used as a vacation home does not qualify.
Household
Who's in the household?
This determines the standard deduction available to you in 2027 and tells us whose income to include.
Whose income counts
Combined disposable income includes the disposable income of you, your spouse or domestic partner, and any co-tenants — defined by DOR as people who have an ownership interest in the residence and live there.
Income from a person who lives with you but has no ownership interest (other than a spouse or partner) is excluded — but any money that person contributes toward household expenses is still counted.
If a co-owner does not live in the residence, only your percentage of ownership qualifies for the exemption. Your county assessor can help with partial-interest cases.
Combined disposable income
Let's estimate your combined disposable income
Combined disposable income is defined specifically by this program — it's different from the adjusted gross income on your federal tax return. It includes income from all sources, even sources that aren't taxable federally. Use the quick estimate for a ballpark, or the guided calculator to mirror the official DOR worksheet line by line.
Include Social Security, pensions, wages, interest, dividends, rental income, and any other income for you, your spouse or domestic partner, and any co-tenants.
Medicare premiums, prescriptions, in-home care, nursing home or assisted living costs, and similar expenses. We'll automatically apply whichever is larger — your itemized costs or the standard deduction — since you can't take both.
Income from all sources
Enter assessment year totals for you, your spouse or domestic partner, and any co-tenants.
Reminder on losses
Capital, business, or rental losses cannot be deducted or used to offset gains or other income.
Deductions
Beginning in 2027, you have two options. Take the standard deduction, or itemize your non-reimbursed expenses. Use whichever gives you the larger deduction.
This is an abbreviated version of the DOR Combined Disposable Income Worksheet (Form 63 0036). Additional allowable deductions exist — your county assessor can review the complete list.
