Maryland Taxes an Inheritance Twice, Once as an Estate and Once as a Beneficiary, Before the Property Tax Even Enters the Picture

Updated August 2026

Maryland reassesses property on a fixed three-year cycle, one-third of each county revalued every year, unrelated to who owns a given parcel. There is no special inheritance-triggered reassessment event here. What makes Maryland genuinely unusual is that it is one of the only states left with both a state estate tax and a state inheritance tax at the same time, collected by two different offices, and the two interact in ways that can generate real interest charges even when the net tax owed is zero.

The Homestead Credit Cap and a Genuine Open Question

Maryland's Homestead Property Tax Credit limits how much a principal residence's taxable assessment can grow year over year for tax purposes, separate from the underlying market assessment. The state and bicounty cap is 10% annually, but counties and municipalities can and do set their own, lower percentages: Baltimore City and Baltimore County cap at 4%, Prince George's County at 3%, Anne Arundel at 2%, while Montgomery County keeps the full 10%. Some municipalities inside a county set their own figure again, ranging as low as 0%.

The statute disqualifies the credit for a taxable year specifically when a dwelling was transferred for consideration to new ownership. An inheritance is not a transfer for consideration, no purchase price changes hands, so on the statute's literal terms that particular disqualifying clause does not apply. That said, we could not find a source stating plainly what happens to an already-built-up cap basis when a home passes by inheritance rather than sale, and the Department of Assessments and Taxation's own FAQ, written around purchasers, says a new homestead application gets mailed once a new deed is recorded, which reads as deed-triggered rather than sale-triggered. If your family is counting on the prior owner's capped basis carrying forward, confirm it directly with SDAT rather than assuming either outcome.

One distinction worth drawing carefully, though it is our own reasoning from general property law rather than a quoted SDAT rule: a surviving joint tenant or tenant by the entirety, someone already on the deed, does not receive a new transfer at all when the other owner dies, survivorship extinguishes the deceased co-owner's interest automatically, with no new deed required. An heir taking by will or intestacy, who was not previously on title, is a genuinely new owner and, per SDAT's stated practice, will be mailed a fresh homestead application once the new deed is recorded.

Two Separate Death Taxes, Collected by Two Separate Offices

Maryland's estate tax is administered by the Comptroller and applies to the estate itself. The exemption has been a flat $5,000,000 for anyone dying on or after January 1, 2019, and it is not tied to the much larger federal exemption, Maryland deliberately decoupled from the federal figure in 2018 legislation. Above that threshold, the rate is capped at 16% of the amount by which the taxable estate exceeds the exemption. A surviving spouse can claim any unused portion of a predeceased spouse's exemption. The return, Form MET-1, is due nine months after death, with extensions of up to six months, or twelve if the filer is out of the country, available, though an extension to file is not an extension to pay.

The inheritance tax is a completely different tax, administered by the Register of Wills in the county where the decedent lived or owned property, and it taxes each beneficiary's share directly at 10%. But the exemptions are broad: a spouse, child, stepchild, grandchild, great-grandchild, parent, and grandparent all pay nothing. Siblings are also fully exempt, but only since July 1, 2000, a detail people commonly get wrong, assuming siblings are taxed the same as more distant relatives. Registered domestic partners have been exempt since October 1, 2023. The 10% rate actually applies only to collateral heirs, nieces, nephews, aunts, uncles, cousins, and unrelated beneficiaries such as friends.

The two taxes are designed to offset each other: inheritance tax actually paid is credited against the gross estate tax liability, and if it equals or exceeds the credit Maryland would otherwise allow, no estate tax is due at all. But the estate tax remains legally owed until the inheritance tax is actually paid, not merely calculated. As a purely hypothetical illustration of the mechanic the Comptroller itself uses: an estate that will ultimately owe $150,000 in estate tax makes two $75,000 inheritance tax payments, one before the nine-month estate tax deadline and one after. Because only half was paid on time, interest accrues on the unpaid $75,000 for the gap period, even though the estate's net liability, once both taxes are netted against each other, comes out to zero. Timing the inheritance tax payment to land before the estate tax deadline is the whole game here.

Appealing the Value

Maryland runs a three-level appeal structure. First, the Supervisor of Assessments, 45 days from the notice of assessment, or, separately, a new owner gets a 60-day window from the date of transfer to appeal, useful for an heir whose ownership starts outside the normal notice cycle. Second, the Property Tax Assessment Appeals Board, an independent agency separate from SDAT, 30 days from the Supervisor's decision, with a hearing required within 120 days for an owner-occupied dwelling. Third and final, the Maryland Tax Court, 30 days from the PTAAB decision, a more formal proceeding requiring your personal presence.

Standing to appeal is granted broadly to any taxpayer, and an heir holding title, even informally pending the close of probate, should qualify. We did not find a source specifically addressing appeal standing for a personal representative or heir before probate formally closes, if that timing matters for your situation, it is worth confirming directly with the Supervisor's office.

The property tax side of a Maryland inheritance is comparatively simple, reassessment runs on its own three-year clock regardless of ownership, and the appeal process is the same one any owner would use. The complexity is entirely on the death-tax side: know which of the two taxes actually applies to your specific relationship to the decedent, and if both are in play, pay the inheritance tax early enough that it actually offsets the estate tax deadline rather than generating avoidable interest.
