If you own a home in Maryland and your household income is under roughly $60,000, you could be leaving hundreds or even thousands of dollars on the table every single year. The Maryland Homeowners’ Property Tax Credit (HTC), sometimes called the “Circuit Breaker” program, caps how much of your income goes toward property taxes — and for tax year 2026, there’s a brand-new supplemental credit for homeowners age 77 and older. Here’s everything you need to know before the October 1, 2026 deadline.
1. What Is the Maryland Homeowners’ Property Tax Credit (HTC)?
The HTC is run by the Maryland State Department of Assessments and Taxation (SDAT) and is designed to keep property taxes affordable relative to what a household actually earns. Unlike many property tax breaks, it isn’t limited to seniors — homeowners of any age can qualify — but it’s especially valuable for retirees living on a fixed income, since Social Security and pension income typically don’t grow as fast as property assessments do.
The program caps your property tax bill based on a percentage of your household income, regardless of what your home is actually assessed at. If your tax bill exceeds that capped amount, the state credits you the difference. Renters have a parallel option too: the Renters’ Tax Credit, for those who don’t own their home but still feel the property tax burden passed through in rent.
2. Who Qualifies in 2026
Income limit
Your combined gross household income — not just your own income, but everyone living in the home — cannot exceed $60,000.
Net worth limit
Your net worth must be under $200,000. Importantly, this does not count the value of the home you’re applying for or money held in qualified retirement accounts (like a 401(k) or IRA), so owning a paid-off house doesn’t automatically disqualify you.
Residency rule
The home must be your principal residence, and you must have lived there at least six months out of the year, including July 1. There are exceptions for people who bought their home recently or who are temporarily away for health reasons.
Ownership requirement
You must own the property or hold a legal interest in it — life estates and certain trust arrangements can still qualify, but the title situation needs to reflect a real ownership interest.
3. How Much You Could Actually Get Back
This is the part most people skip past, but it’s worth understanding because the formula is genuinely generous at lower income levels. The state doesn’t tax your first $8,000 of income at all for credit purposes, then applies increasing percentages as income rises:
| Income Bracket | Percentage Counted Toward Tax Limit |
|---|---|
| $0 – $8,000 | 0% |
| $8,001 – $12,000 | 4% of that portion |
| $12,001 – $16,000 | 6.5% of that portion |
| Above $16,000 | 9% of that portion |
Worked example
Say a household earns $16,000 a year and their actual property tax bill is $990. Under the formula:
- First $8,000 of income → $0 counted
- Next $4,000 (to $12,000) → 4% = $160
- Next $4,000 (to $16,000) → 6.5% = $260
- Total amount the household is expected to pay toward property tax: $420
Since the actual bill is $990 and the household is only expected to pay $420, the state credits the difference: a $570 credit, applied directly to the tax bill.
Two limits to keep in mind: the credit only applies to tax on the first $300,000 of your home’s assessed value, and it does not cover water or sewer charges billed separately.
4. New for Tax Year 2026 — The Age 77+ Supplemental Credit
Starting with tax year 2026, Maryland is offering a brand-new supplemental credit specifically for homeowners age 77 and older. Unlike the standard HTC, this one is a sliding-scale credit calculated as a percentage of your Maryland state income tax liability, not your property tax bill.
You have to choose one, not both
This is the single most important thing to understand about the new credit: it is mutually exclusive with the standard Homeowners’ Tax Credit. You cannot claim both in the same year — you have to pick whichever one benefits you more.
Which one should you check first?
Here’s a simple way to think about it before you file:
- If your income is very low and your property tax bill is high relative to that income — the standard HTC formula above is likely to give you the bigger credit.
- If your income (and therefore your state income tax liability) is moderate, and your property tax bill is relatively modest compared to your income — the Age 77+ Supplemental Credit may work out better.
- If you’re not sure, calculate both or call SDAT (numbers below) before submitting your application, since you can only pick one for the year.
5. How and When to Apply
Deadline
The application deadline is October 1, 2026. This is not a one-time application — you must reapply every single year, even if nothing about your income or home has changed.
File early for faster processing
If you file by April 15, the credit is applied directly to your July property tax bill, so you never have to pay the full amount up front. If you file later — anytime up to the October 1 deadline — you’ll instead receive a revised bill after the fact.
How to submit
You can apply online through Maryland’s OneStop portal, or mail the paper HTC-1 form (available in both English and Spanish) to:
SDAT’s Homeowners’ Tax Credit Program
P.O. Box 49005
Baltimore, MD 21297
Do not email the application. SDAT does not accept applications by email for data-security reasons — online portal or physical mail only.
6. Common Mistakes That Get Applications Rejected
- Forgetting to reapply every year. The HTC does not renew automatically — missing a year means missing that year’s credit entirely.
- Miscalculating net worth. A common error is forgetting to exclude the home itself and qualified retirement accounts, which can make someone think they’re over the $200,000 limit when they’re not.
- Confusing the HTC with the Homestead Tax Credit. The Homestead credit caps how fast your assessment can increase year to year and has nothing to do with income — it’s a completely separate program from the income-based HTC.
7. Where to Get Help
If you get stuck filling out the form or aren’t sure which credit applies to you, you don’t have to figure it out alone:
- SDAT phone lines: 410-767-4433 or 1-800-944-7403
- Your local Area Agency on Aging or AARP Maryland volunteer tax help programs can walk you through the paperwork in person, often for free
The Bottom Line
The Maryland Homeowners’ Property Tax Credit is one of the most underused benefits available to homeowners in the state, largely because people assume it’s only for seniors or assume they earn too much to qualify. With the income cap at $60,000 and the new Age 77+ Supplemental Credit adding another option for older homeowners in 2026, it’s worth five minutes of your time to check both formulas before the October 1 deadline arrives.
