Maryland SDAT Triennial Reassessments and Filing Your Homestead Tax Credit Application
Updated October 2026
A Maryland property’s sale price, assessed value, and taxable assessment are related but different numbers. Understanding that distinction helps explain why a seller’s tax bill may not predict yours and why a Homestead Tax Credit does not freeze the total cost of owning a home.
Read the three-year reassessment correctly
The Maryland Department of Assessments and Taxation reassesses real property on a triennial cycle. Properties are divided into assessment groups, so a portion of each jurisdiction is reviewed annually. Increases are generally phased in over three years; decreases generally take effect without the same gradual phase-in.
Your assessment notice identifies the new value and applicable assessment information. Review the property description, land characteristics, and improvements for errors. If the valuation appears unsupported, follow the appeal instructions and deadline printed on the notice rather than waiting for a mortgage escrow statement.
The Maryland Department of Assessments and Taxation (SDAT) is the official starting point for assessment records, reassessment information, and application access.
File for Homestead protection on your residence
The Homestead Tax Credit limits annual growth in the taxable assessment used for eligible owner-occupied property. The state cap is 10%, while local caps can be lower: Baltimore City and Baltimore County use 4%, and Anne Arundel uses 2%.
These percentages do not cap market-value appreciation or guarantee that the entire tax bill rises by no more than the stated percentage. Tax rates, separate charges, improvements, and eligibility changes can affect the amount due.
To prepare your application:
- Verify the property account information in SDAT records.
- Confirm that the property meets principal-residence requirements.
- Follow SDAT’s current online or paper application instructions.
- Retain your submission confirmation and check application status.
- Do not assume the seller’s credit transfers to you.
Homestead protection differs from Maryland’s income-based Homeowners’ Property Tax Credit. Check each program separately rather than treating their names as interchangeable.
Plan for billing and escrow changes
Eligible primary residences commonly use semiannual property-tax billing. That billing schedule does not necessarily change your monthly mortgage payment schedule: an escrowed loan usually collects estimated taxes each month.
Use the monthly payment calculator with a purchase-specific tax estimate, not merely the seller’s current bill. Keep one-time purchase taxes separate by reviewing the transfer and recordation guide.
The Consumer Financial Protection Bureau explains mortgage payment components and escrow. Revisit your budget when reassessment notices or escrow analyses arrive, especially during the first years after buying.

Editorial Methodology & Primary Sources
Verification date: Not recorded; check the primary source and lender timestamp before relying on an estimate.
Rate comparisons use participating lender feeds, not a whole-market survey or guaranteed offers. Freddie Mac PMMS is a market benchmark, not a personalized quote. Calculator models rely on published regulatory formulas and disclosed assumptions rather than fabricated first-person loan testing.
Monthly principal and interest use the amortization formula P × r / (1 − (1 + r)−n), where r is the monthly note rate and n is the number of payments; at zero interest use P / n. PITI adds monthly property taxes and homeowners insurance; PMI is separate. APR includes applicable finance charges under Regulation Z and is not the note rate used for payments.

The payment snapshot uses illustrative annual taxes of 1% of home price, $1,200 insurance and 0.5% PMI below 20% down, not verified local quotes. Other calculators disclose their inputs and assumptions. Published guidance and lender feeds may change independently; confirm current program rules, taxes and offers before a decision.
