The Maryland Homestead Tax Credit limits how much your property tax assessment can increase each year — capped at 10% in Montgomery County. Every owner-occupant who uses the home as their primary residence qualifies, but you have to file a one-time application with the state. New buyers who skip this step have no cap protection when their next reassessment comes in. In a county where 2026 property values jumped 12.2%, that’s not a small exposure.
What is the Maryland Homestead Tax Credit and how does it protect Bethesda buyers?
The Maryland Homestead Tax Credit caps the annual increase in your property’s taxable assessment at a fixed percentage — 10% in Montgomery County — so your property taxes can’t spike dramatically from one year to the next, even if the market does. Every owner-occupant who uses the home as their primary residence qualifies, but you have to file a one-time application with the Maryland State Department of Assessments and Taxation (SDAT) to activate it. New buyers who don’t file this application have no cap protection when their property is reassessed.

There’s a conversation I have with almost every buyer after closing that most agents skip entirely. It’s not about moving logistics or paint colors. It’s about a one-time filing that could protect you from hundreds or even thousands of dollars in additional property taxes every year — compounding for as long as you own the home.
It’s called the Maryland Homestead Tax Credit. If you just bought in Bethesda or anywhere in Montgomery County, this is the next thing on your list.
What the Homestead Tax Credit Actually Does
Maryland reassesses properties on a rotating three-year cycle. SDAT visits roughly one-third of all properties each year, and when your turn comes up, the new assessed value can jump significantly — especially in a market like Bethesda, where values have been rising sharply.
In January 2026, SDAT released its latest reassessment round showing a 12.2% increase in Montgomery County property values. That’s not a market anomaly — it’s a reflection of where prices have been and where they’re going.
Without protection, that 12.2% assessment increase translates directly into a larger tax bill. Your assessment goes up, your taxable value goes up, and you pay more — regardless of whether you expected it or planned for it.
The Homestead Tax Credit changes this. Once you’ve filed and been approved, the state and county can only tax you on an assessment increase of up to 10% per year over the prior year’s capped value. The assessment above that cap still exists on paper, but you’re not taxed on it. The gap between your full market-value assessment and your capped value is where the credit lives — and in a rising market, it grows every year you stay in the home.
The Numbers in Bethesda’s Market
Let’s put real figures to this. Say you purchase a home in Bethesda at $1.2M, and it’s assessed at close to that value when you buy.
Two years later, your property comes up for reassessment, and the new value is $1.346M — a 12.2% increase, in line with what Montgomery County saw in 2026.
Without the Homestead Tax Credit:
Your taxable assessment jumps by the full $146,000. At Montgomery County’s combined property tax rate of roughly $1.02–$1.03 per $100 of assessed value, that’s an additional $1,450–$1,500 per year in property taxes, starting immediately.
With the Homestead Tax Credit:
Your taxable assessment can only increase by 10% — from $1.2M to $1.32M. The remaining $26,000 in assessment increase is shielded. You avoid roughly $260–$270 per year in additional taxes in that first reassessment cycle.
That might sound modest in isolation. But here’s what matters: the cap applies every year, and the gap compounds. If assessments keep rising, your capped value falls further behind the full market value each cycle. By year five or six in a strong market, the annual savings can run $1,500–$2,000+ per year — on a home you’re not planning to sell.
The credit doesn’t change what your home is worth. It just limits what you’re taxed on.
Who Qualifies
The Homestead Tax Credit applies to:
- Owner-occupants only. The property must be your principal residence — not a rental, not a second home, not an investment property.
- Primary residency for at least six months of the year, including July 1, which is the date Maryland uses for tax year eligibility.
- One property per household. You can only claim the credit on the home you actually live in.
If you’re buying in Bethesda as a primary residence — which is the vast majority of buyers in this market — you qualify. The credit doesn’t phase out based on income, purchase price, or loan type.
How to Apply
This is a one-time filing. You don’t renew it annually. You do it once, you’re covered as long as you own the home and use it as your primary residence.
Application options:
- Online via Maryland OneStop — the fastest path. Search “Homestead Tax Credit Eligibility Application” at onestop.md.gov. Takes about five minutes.
- Paper application through SDAT — download the form from dat.maryland.gov, fill it out, and mail it to SDAT.
Before you apply, check whether an application is already on file from the previous owner. Go to sdat.dat.maryland.gov/RealProperty, select Montgomery County, and search your property. If the status shows “Approved” or “Application Received,” you don’t need to file again. If it shows “No Application,” you do.
When to apply after buying: There’s no strict filing deadline tied to your closing date — you can file at any time after purchase. That said, the earlier you apply, the sooner you’re protected for the next reassessment cycle. Filing within the first few months after closing is the right move.
One nuance in Montgomery County: the Homestead Tax Credit application is also connected to the county’s Income Tax Offset Credit (ITOC), a separate credit that appears on your property tax bill. For the ITOC to appear on bills starting July 1, 2026, applications needed to be on file by May 1, 2026. If you’re buying after that date, your Homestead Credit will still activate for future cycles — the ITOC timing is a separate consideration worth confirming with Montgomery County Finance when you apply.
A Common Mistake Buyers Make
Some buyers assume the Homestead Tax Credit transfers automatically when they purchase. It doesn’t.
When a property sells, the previous owner’s Homestead Tax Credit protection ends. The assessment gets reset to the new sale price for the incoming owner, and the cap starts fresh — but only if you’ve filed your own application. If you buy and never apply, you’re unprotected for every reassessment cycle that follows.
Your lender won’t remind you. Your title company handles the closing transaction, not ongoing tax management. Your real estate attorney signs off on the deed, not the tax filings. This one falls to you — and most buyers don’t know it until they see a tax bill that’s significantly higher than they expected.
Understanding your Montgomery County property tax obligations before and after closing is part of knowing the true carrying costs of homeownership in this market. The Homestead Tax Credit is one of the most valuable tools available to reduce those costs long-term — it just requires you to take action.
The Montgomery County Layer
Maryland sets the statewide cap at 10%. Montgomery County can set a lower local cap, but has opted to match the state at 10% as well — so you get the same protection from both the state and county tax portions of your bill.
The Town of Kensington, which falls within Montgomery County, has set its own cap at 5% — meaning Kensington residents actually get tighter protection than the county average. If you’re buying in Kensington specifically, confirm the local cap applies to your property.
For most Bethesda, Potomac, Chevy Chase, North Bethesda, and North Potomac buyers, the 10% state and county cap is what governs your Homestead Tax Credit protection.
One More Thing: This Connects to Your Net Proceeds If You Ever Sell
When you sell a property that has accumulated a large gap between its capped taxable value and its full market-value assessment, the buyer’s property taxes will reset to the full market value in the next cycle.
This can come up in buyer conversations during the purchase process — “what are the property taxes going to be after I buy?” — where the answer may be significantly higher than what the current owner is paying because of how far their Homestead Credit protection has built up over the years.
If you’re ever selling, this is something to account for when helping buyers understand their carrying costs. And if you’re thinking through how to calculate your net proceeds from a Bethesda home sale, the property’s tax history is one of the factors that can affect marketability and buyer expectations.
Frequently Asked Questions
What is the Maryland Homestead Tax Credit?
The Maryland Homestead Tax Credit limits how much your property’s taxable assessment can increase from one year to the next. In Montgomery County, the cap is 10% per year. The credit applies to owner-occupied primary residences only, and you must file a one-time application with SDAT to activate it. Once approved, you stay protected as long as you live in the home as your primary residence.
Does the Maryland Homestead Tax Credit apply to new home purchases?
Yes, but the previous owner’s application does not transfer to you. When you buy a property, the Homestead Tax Credit resets — and you need to file your own application with SDAT after closing. New buyers who don’t file lose cap protection for future reassessment cycles.
How do I apply for the Maryland Homestead Tax Credit in Montgomery County?
Apply online through Maryland OneStop at onestop.md.gov using the Homestead Tax Credit Eligibility Application, or mail a paper form to SDAT. Before applying, check whether a prior application is on file by searching your property at sdat.dat.maryland.gov/RealProperty. If the status shows “Approved,” you don’t need to refile. The application is a one-time filing — there’s no annual renewal.
How long does it take for the Homestead Tax Credit to take effect?
The credit doesn’t reduce your taxes in the year you apply — it limits future assessment increases. The protection kicks in when SDAT reassesses your property, which happens on a three-year rotating cycle. Once your application is approved and your property comes up for reassessment, the 10% cap applies to the increase in taxable value.
What happens to the Homestead Tax Credit if I sell my home?
Your protection ends when you sell. The new buyer’s taxable assessment resets to the full market value, and the buyer starts from zero with no cap in place until they file their own Homestead Tax Credit application. If the previous owner had accumulated significant cap protection, the new buyer’s property taxes can be meaningfully higher than what the seller was paying — worth understanding on both sides of a transaction.
The Homestead Tax Credit is one of the most underused protections available to Maryland homeowners. In a county where assessments jumped 12.2% in one reassessment cycle, the difference between buyers who filed and those who didn’t is real money — and it compounds every year.
