The Maryland Homestead Cap Does Not Come With the House
Program and regulatory figures verified September 25, 2026. Details change; confirm your scenario with us.
Maryland's homestead credit is one of the most valuable things a long-tenured owner has, and it is also one of the least portable. It ends at the settlement table.
What the credit actually does
The Homestead Tax Credit does not cap your assessment. It caps how fast the portion of the assessment you are taxed on can grow.
Md. Tax-Property 9-105 sets out the arithmetic. For each taxable year the credit is calculated by multiplying the prior year's taxable assessment by the homestead credit percentage, subtracting that amount from the current year's assessment, and if the difference is a positive number, multiplying the difference by the applicable property tax rate for the current year.
That credit is what keeps a long-tenured owner's bill below what the market value would otherwise produce. After a decade of rising assessments the gap can be substantial, and it is invisible until it disappears.
The percentage, and who sets it
The homestead credit percentage is 110% for the State property tax and for any property tax imposed for a bicounty commission. For county and municipal property tax the statute provides that it may not be less than 100% or exceed 110% for any taxable year, and shall be expressed in increments of 1 percentage point.
So the range is a cap on growth of between 0% and 10% a year, set locally. A jurisdiction sitting at 100% is holding the taxable assessment flat. One at 110% allows 10% growth. Check where yours sits, because it determines how much protection you had and therefore how much you lose.
The reset
Here is the provision that governs a move. The credit is not available for a taxable year where, during the previous taxable year, the dwelling was transferred for consideration to new ownership. The statute lists three other disqualifying events alongside it: a change in zoning classification initiated or requested by the homeowner or someone with an interest in the property, a substantial change in the use of the dwelling, and an assessment that was clearly erroneous.
A sale is the first of those. The accumulated cap belongs to the tenure, not the building, and it does not convey.
The practical consequence for a Maryland move-up is direct and it is often missed. Whatever the seller's tax bill shows, it may reflect years of capped growth that you will not inherit. Underwrite the new payment on the current assessment, not on the bill the listing quotes.
The 6-month test, which matters during an overlap
Section 9-105(a)(5)(i)(1) defines a dwelling as a house used as the principal residence of the homeowner and actually occupied, or expected to be actually occupied, by the homeowner for more than 6 months of a 12-month period beginning with the date of finality for the taxable year for which the credit is sought.
During a year where you own two Maryland homes and occupy the new one, the departing home can fail that test. There is a narrow exception where a homeowner cannot actually reside in a dwelling because of illness or need of special care, with the credit available again for the taxable year following resumption of residency, but that is not a move-up provision.
The application, and the date
Eligibility has to be established by application filed on or before June 30 for the following taxable year, and the statute warns that failure to file a timely application may result in disqualification from the Homestead Tax Credit Program for the following taxable year.
So a Maryland buyer has two things to do that a seller does not: file the application on the new house, and budget for an uncapped assessment in the meantime. Neither is difficult; both are easy to forget in the middle of a move.
The other half of the Maryland picture
Maryland also taxes the act of borrowing against your departing home, which is unusual and which changes the structure comparison. That is on the recordation tax page. The three financing routes are compared on the structures page, and the whole plan sits on the Maryland guide.
Frequently asked questions
Does the Maryland Homestead Tax Credit transfer to a new owner?
No. Under Md. Tax-Property 9-105 the credit is unavailable for a taxable year where, during the previous taxable year, the dwelling was transferred for consideration to new ownership. The accumulated cap belongs to the prior owner's tenure and does not convey with the property.
What does the Maryland Homestead Tax Credit actually cap?
Growth in the taxable assessment, not the assessment itself. The credit is calculated by multiplying the prior year's taxable assessment by the homestead credit percentage, subtracting that from the current year's assessment, and multiplying any positive difference by the current year's tax rate.
What is the homestead credit percentage in Maryland?
110% for the State property tax and for any property tax imposed for a bicounty commission. For county and municipal property tax it may not be less than 100% or exceed 110% in any taxable year, expressed in increments of 1 percentage point, so local caps on growth range from 0% to 10%.
Should I use the seller's tax bill to estimate my Maryland payment?
No. The seller's bill can reflect years of capped growth under the Homestead Tax Credit, and that protection ends when the dwelling is transferred for consideration to new ownership. Underwrite the payment on the current assessment instead.
How long do I have to live in a Maryland home to claim the credit?
More than 6 months of a 12-month period beginning with the date of finality for the taxable year, under Md. Tax-Property 9-105(a)(5)(i)(1), and the dwelling must be used as your principal residence. A departing home can fail that test in an overlap year.
When is the Maryland Homestead Tax Credit application due?
On or before June 30 for the following taxable year. The statute provides that failure to file a timely application may result in disqualification from the Homestead Tax Credit Program for the following taxable year.
