Why Does a Maryland Property Tax Bill Go Up Even With the Homestead Credit?
Your assessment barely moved, but your Maryland property tax bill still went up.
The Homestead credit limits how fast your taxable assessment can rise.
But it can’t stop your tax rate from going up.
Here’s why a Maryland property tax bill can go up even with the Homestead credit, and what to check if yours looks wrong.
Note: This is general information, not legal or tax advice. Assessment rules and credit limits are subject to change, so confirm the current details with the Maryland State Department of Assessments and Taxation (SDAT) or your local assessment office.
Why a Maryland Property Tax Bill Still Rises With the Homestead Credit
Maryland’s Homestead Tax Credit limits how much your home’s taxable assessment can increase each year.
Every county and municipality has to hold that increase to 10% or less, though local governments can set the limit lower.
Rates are a separate matter.
Your bill multiplies your assessment by the tax rates that the state, your county and your town each set.
It doesn’t limit your home’s market value, either.
What it does is waive the tax on the part of an increase that goes past your cap.
Say your taxable assessment rises 8% in a county that allows 10%.
No credit applies in that case because the increase never crosses the cap.
Tax Rate Changes the Credit Can’t Cap
The Homestead credit can’t cap a tax rate, so a higher rate lands on your bill even when your assessment holds steady.
SDAT doesn’t set tax rates.
The state, each county and each municipality set theirs, and those rates can increase, decrease or stay the same from year to year.
Maryland law requires SDAT to calculate a Constant Yield for every county and local jurisdiction, a benchmark that flags when a government is raising more revenue.
A government that keeps last year’s rate can still be raising taxes, if that rate sits above the Constant Yield level.
For rate questions, you’ll want to go to your county or town officials.
How a Capped Assessment Still Raises Your Bill
Take a Homestead-credit home with a $400,000 taxable assessment and a rate of $1.10 per $100.
The bill is $4,400.
Next year the assessment rises 10%, right at a 10% cap, and the rate rises to $1.15.
The new bill is $5,060, which is $660 more, even though the assessment never went past the cap.
These are made-up figures for illustration, not any county’s rate.
How Three-Year Phase-Ins Add Up
The assessment behind a Maryland property tax bill follows a three-year cycle because SDAT reassesses each property once every three years.
When your home is reassessed, the increase from the old market value to the new one is split equally across three years.
It adds up.
The second and third steps still show up on later bills, even if nothing about your home changes.
Phase-ins apply only to increases, since a decrease takes effect in full the same tax year.
Homes in the group reassessed in 2026 gained 13.2% in value on average over a full three-year period, not one year’s growth.
Split into three equal steps, that average comes to roughly 4% on each bill.
An average step like that never triggers the credit in a county that allows 10%.
In a county with a much lower cap, the credit trims that same step.

County and Town Caps That Don't Match
The Homestead credit follows a different cap depending on where you live because every county and municipality sets a percentage between 0% and 10%.
That means the county portion and the town portion of one bill can follow different caps.
Annapolis shows how far apart they can sit, since the city's cap is 10% while Anne Arundel County's is 2%.
Your address decides it.
SDAT publishes a yearly table of tax rates and Homestead caps for every county and town, so you can look up both of yours.
Some counties allow the full 10%, while others set a far lower limit.
A lower cap trims more of each phase-in step.
A 10% cap may never apply at all.
When the Homestead Credit Goes Missing
The Homestead credit only helps while you qualify, and a missing application can leave you paying tax on the full increase.
State law requires a one-time application, and SDAT's property search shows your status.
The filing is one-time.
If it reads “No Application,” file another one.
The home has to be your principal residence.
You have to live in it on July 1 of the tax year.
A sale ends the credit for that owner.
Buyers file a fresh application, as our deed-transfer guide explains.
A zoning change you requested that raised its value, or a substantial change in how you use the home, can cost you the credit.
If SDAT denies your application, you have 30 days to appeal to the Property Tax Assessment Appeal Board.
The Other Credit That Needs Renewing
Maryland's Homeowners' Property Tax Credit is a separate program from the Homestead credit, and it's the one you have to apply for every year.
It's based on income, and it credits back property taxes that run above a set percentage of your household income.
Combined gross household income can't exceed $60,000, and your net worth has to be under $200,000, not counting your home or retirement savings.
The deadline is October 1 each year, but the state recommends filing by April 15 so the credit can take effect on your first bill.
It isn't automatic.

Checking a Bill That Looks Wrong
If your property tax bill looks higher than your Homestead credit should allow, your assessment notice is the first place to look.
It lists the old market value as well as the new one, so you can see how big a jump the phase-in is spreading across three years.
If you think the new market value is wrong, you can appeal within 45 days of the notice date.
Appeals cover value.
A rate complaint still goes to local officials.
For billing and payment questions, your local billing office is the one to call.
FAQ
Here are answers on the Homestead credit and a rising bill.
Does the Homestead credit cap my Maryland property tax bill?
No.
The credit limits how much your taxable assessment can increase each year, but it doesn't limit the tax rate your county or town applies.
How much can my assessment go up each year with the Homestead credit?
State law caps the increase at 10% a year.
Your county or town may set a lower limit, so your cap depends on where you live.
Do I have to reapply for the Homestead credit every year?
No.
The application is a one-time filing while you stay in the home, unlike the Homeowners' Property Tax Credit, which needs a new application every year.
Who sets Maryland property tax rates?
Each county and municipality sets a rate, and the state sets one too.
SDAT sets assessments, not rates.
How long do I have to appeal a Maryland property assessment?
You have 45 days from the date on your assessment notice.
The appeal covers your home's value, so a tax rate complaint goes to your county or town instead.
