The Homestead Tax Credit Most Prince George's County Homeowners Never File (Part 1 of 5: The Southern Maryland Money Guide)
This is Part 1 of The Southern Maryland Money Guide from Donnell Williams Jr. and DMV Prime Properties, a five-part series on the costs of owning a home in Prince George's and Charles County that nobody explains at the closing table.
There is a particular kind of phone call that comes in every August. A homeowner opens their property tax bill, sees a number that does not match the one they budgeted for, and calls the person who sold them the house. Sometimes that number is a few hundred dollars higher. Sometimes it is a few thousand. And almost every time, the conversation ends at the same place: nobody ever told them about a form they were supposed to file.
That form is the Maryland Homestead Tax Credit application. It is one page. It is free. It has to be filed exactly once. And in Prince George's County, filing it is worth more than in most of Maryland.
The bill that arrives after the boxes are unpacked
Donnell Williams Jr., Broker-Owner of DMV Prime Properties, sees this pattern most often with buyers who closed within the last two or three years. The mortgage payment was quoted, escrowed, and locked in before settlement. Then the county reassesses, the escrow account gets recalculated, and the payment moves.
A Prince George's homeowner described exactly this online in August 2026: a county tax bill that had risen 62 percent from one assessment cycle to the next. He had gone looking for an explanation, found the Homestead Tax Credit in the process, and applied that night. His question afterward was the one everyone asks: can this be applied backward, or has that money simply gone?
Another Prince George's owner posted the same month that his taxes had increased by more than $2,500 year over year, roughly $200 a month on the mortgage payment, on a single income supporting a household of three. He had also only learned about Homestead when the bill arrived, two years into owning the home.
Neither of these people did anything wrong. They were never told.
What the Homestead Tax Credit actually does
The credit is often misunderstood as a discount. It is not. It is a cap.
Maryland's State Department of Assessments and Taxation (SDAT) reassesses every property in the state on a three-year cycle. When a reassessment raises the value of a home, the Homestead Tax Credit limits how much of that increase can be taxed in a single year. The portion above the cap is credited off the bill.
To qualify, the property has to be the owner's principal residence, occupied for at least six months of the year including July 1. It can be claimed on only one property. And the property must not have been transferred, rezoned, or substantially changed in use during the prior tax year.
Two things make this credit unusual. First, it is not automatic. Homeowners have to submit a one-time application to SDAT. Second, once it is approved, it generally does not need to be renewed unless SDAT requests it or eligibility changes.
The number that matters: 3 percent in Prince George's, 7 percent in Charles
This is where local knowledge earns its keep.
The state of Maryland sets a homestead cap of 10 percent. But each county and municipality can set its own cap at 10 percent or lower. According to SDAT's published County and Municipal Homestead Credit Percentages table, Prince George's County uses a 3 percent cap. Charles County uses 7 percent.
That difference is not cosmetic. A Prince George's homeowner with the credit in place sees taxable assessed value climb no more than 3 percent in a year, no matter what the reassessment says. A Charles County homeowner is capped at 7 percent. Someone in a jurisdiction using the full state cap absorbs up to 10 percent.
Put another way: Prince George's County offers one of the more protective homestead caps in Maryland, and a large number of its homeowners are not using it.
One note of caution worth stating plainly. Prince George's County's own finance webpage describes the county cap differently than SDAT's published cap table does. Donnell recommends every homeowner confirm the current figure directly with SDAT before relying on it, and treat any number found on a blog, including this one, as a starting point rather than the final word.
What this summer's closing data says about the stakes
Numbers make the case better than adjectives.
Across 1,397 closed sales in Prince George's and Charles County that settled between July 1 and August 22, 2026, the median annual property tax figure recorded in the MLS was $5,335 in Prince George's and $4,948 in Charles County. That is $445 and $412 a month respectively, before a single dollar of principal, interest, or insurance.
On a $5,335 annual bill, the gap between a 3 percent capped increase and an uncapped reassessment year is not a rounding error. It is the difference between a payment that behaves the way the buyer expected and a payment that quietly grows.
Prince George's County median sale price across those closings was $449,000. Charles County came in at $440,000. These are not luxury tax bills attached to luxury homes. They are ordinary bills on ordinary houses in Fort Washington, Waldorf, Clinton, Brandywine and Upper Marlboro.
The credit people keep confusing it with
There are two separate Maryland credits in play, and the conversation online consistently blends them.
The Homestead Tax Credit is the assessment cap described above. It is not based on income. Anyone who owns and occupies a principal residence in Maryland is eligible, and the benefit depends entirely on how much the assessment rises.
The Homeowners' Property Tax Credit is a different program, and it is income-based. Combined gross household income cannot exceed $60,000. Net worth, excluding the home itself and qualified retirement accounts or IRAs, must be under $200,000. The credit is calculated on a sliding formula against income, and the application deadline is October 1 each year, though SDAT advises filing by April 15 so the credit can be applied to the July bill rather than refunded later.
That retirement-account exclusion matters more than most people realize. The Prince George's homeowner who posted about his $2,500 increase mentioned having less than $50,000 in savings and retirement combined, and assumed his household income disqualified him outright. It probably does, since the income limit is a hard threshold. But the net worth test being separate from the income test is the kind of detail that costs people the credit when they self-disqualify without reading the rules.
Donnell is a broker, not a tax advisor or an attorney, and neither of these credits should be evaluated based on a blog post. The point of laying them out side by side is simpler: they are different programs with different tests, and confusing one for the other is why people conclude they do not qualify for anything.
Can it be applied retroactively?
This is the question that generates the most conflicting answers online, and the honest response is that homeowners get different outcomes.
Several Prince George's residents have reported waiting a year or more for approval, with the credit eventually appearing on a later bill rather than producing a refund on the current one. Maryland statute does contemplate retroactive application in defined circumstances, and at least one resident with prior experience inside the county assessor's office noted that outcomes appear to vary with how recently the property was purchased.
What that means practically is this: the answer depends on the specific file, and the office that can give it is SDAT, not the internet. What is not in dispute is that filing later is strictly worse than filing now, and that an unfiled application produces no benefit at all.
Why the payment moves even when the rate does not
Part of what makes this feel like an ambush is the mechanics of escrow.
Most buyers in Prince George's and Charles County escrow taxes and insurance with their mortgage payment. The lender estimates the annual bill, divides it by twelve, and collects it monthly. Once a year the servicer runs an escrow analysis and compares what was collected against what was actually paid out.
When an assessment rises, two things happen at once. The escrow account has to make up the shortfall from the year that already passed, and the monthly collection has to increase to cover the new higher bill going forward. That is why a homeowner can see a payment jump by more than the tax increase itself, and why the increase feels retroactive even though the mortgage rate never changed.
A capped assessment does not eliminate that mechanic. It limits how far it can travel in any single year.
How to check whether you filed, and how to file
Every Maryland homeowner should do three things this month.
Look up the property in SDAT's Real Property Search and check whether a Homestead application is on record. Many people who believe they filed at closing did not, because the title company handled a different set of forms entirely.
If it is not on file, submit the one-time application through Maryland OneStop, or by mail or fax to SDAT. There is no fee and no annual renewal.
Then set expectations. Approval is not immediate. Homeowners routinely report waiting months. That is normal and not a sign the application failed.
SDAT can be reached at sdat.homestead@maryland.gov, toll free at 1-866-650-8783, or at 410-767-2165 in the Baltimore area.
What this means if you are buying right now
Prince George's County closed July 2026 with 2,083 active listings, up 15.5 percent year over year and the highest July inventory level in five years, according to the Prince George's County Association of REALTORS. Buyers finally have choice. Average days on market rose 27.6 percent to 37 days, and sellers still received 99.1 percent of their original list price.
More choice is good news. It also means more buyers are about to become first-time Maryland homeowners who have never seen a Maryland tax bill. Donnell builds the Homestead application into the post-closing checklist for every DMV Prime Properties client for exactly that reason. It is a five-minute task that protects a payment for as long as they own the house.
If a home was purchased in Prince George's or Charles County in the last three years and nobody mentioned the Homestead Tax Credit, that is worth checking today. Donnell and the DMV Prime Properties team are happy to walk any local homeowner through where to look, whether or not they bought the house through the brokerage, and to review what the current assessment means for a future sale. Reach the office at 301.818.0313 or donnell@dmvprimerealty.com to set up a time.
Part 2 of The Southern Maryland Money Guide covers the other number that surprises buyers: why the mortgage rate they were quoted is higher than the one they keep seeing advertised.
