Buying or selling property in Baltimore County, Maryland comes with a layer of taxes most people don’t fully understand until they’re sitting at the closing table. There are two transfer taxes — one from the State of Maryland and one from Baltimore County itself — plus recordation taxes and recording fees on top of that. Each one has its own rate, its own exemptions, and its own rules about who pays.
This guide explains exactly how our Baltimore County Transfer Tax Calculator works, step by step. We’ll cover every rate, every exemption, and give you two worked examples at each stage so you can check your own numbers with confidence.
Step 1: Calculating “Consideration” — the Taxable Base
Before any tax can be computed, you need to know the correct starting number. In Maryland, that number is called consideration, and it is not simply the sale price.
Under Maryland Tax-Property Article §13-203, consideration equals the sale price plus any mortgage or debt the buyer assumes from the seller. If the buyer takes over an existing loan, that loan amount gets added to the price before taxes are calculated. On the other hand, debt that the seller forgives — or seller-paid closing costs — does not increase the taxable consideration. Neither does personal property like furniture or appliances included in the sale.
Example A
Standard Sale, No Assumed Debt
A buyer purchases a Baltimore County home for $300,000 cash. There is no mortgage being assumed.
Consideration = $300,000 + $0 = $300,000
Example B
Sale with Assumed Mortgage
A developer buys two adjacent lots for a combined price of $200,000 but also assumes the seller’s existing mortgage of $50,000.
Consideration = $200,000 + $50,000 = $250,000
Step 2: Maryland State Transfer Tax (0.5%)
Maryland imposes a statewide transfer tax on every deed conveying real property. The standard rate is 0.5% of consideration, set by Maryland Tax-Property Article §13-203. This applies to almost every property sale in the state, including all transactions in Baltimore County.
There is one important rate reduction: if the buyer is a first-time Maryland homebuyer purchasing the property as their principal residence, the state rate drops to 0.25%. A first-time buyer is defined as someone who has never previously owned a Maryland principal residence. When this reduced rate applies, the law requires that the seller pays the entire state tax — even if the purchase contract says the parties will split transfer taxes. This rule comes directly from §13-203 and cannot be contracted around.
Example A
Standard Buyer (Not First-Time)
Sale price of $300,000, buyer has previously owned a Maryland home.
State Transfer Tax = 0.5% × $300,000 = $1,500
Example B
First-Time Maryland Homebuyer
Sale price of $250,000, buyer is buying their first-ever Maryland principal residence.
State Transfer Tax = 0.25% × $250,000 = $625 (paid entirely by the seller by law)
Key rule: The first-time buyer rate only applies when the buyer will actually occupy the home as their principal residence. If the buyer plans to rent it out or use it as a second home, the full 0.5% rate applies even if they’ve never owned Maryland property before.
Step 3: Baltimore County Transfer Tax (1.5%)
Separate from the state, Baltimore County imposes its own local transfer tax at 1.5% of consideration, authorized under the Baltimore County Code (Chapter 5). This is one of the higher county rates in Maryland, and it applies to essentially all property sales in the county.
However, two major exemptions reduce or eliminate this tax for many residential buyers:
The $22,000 Owner-Occupied Exemption
If the buyer will use the property as their principal residence — meaning they’ll occupy it as their primary home for at least seven of the next twelve months — the first $22,000 of consideration is exempt from the 1.5% county tax. The buyer must sign a homebuyer’s affidavit confirming their intent to occupy. This exemption applies to the buyer’s portion of the tax unless the purchase contract states that the seller pays all transfer taxes.
Example A
Owner-Occupied Purchase, Not First-Time
Sale price of $300,000, buyer will occupy the home, no assumed debt.
Taxable base = $300,000 − $22,000 = $278,000
County Transfer Tax = 1.5% × $278,000 = $4,170
Example B
Investment Property, No Exemption
Sale price of $250,000 for a rental property. Buyer will not occupy as a primary residence.
Taxable base = $250,000 (no exemption applies)
County Transfer Tax = 1.5% × $250,000 = $3,750
First-Time Homebuyer Full Exemption (Effective July 1, 2025)
Beginning July 1, 2025, Baltimore County enacted a complete exemption from the 1.5% county transfer tax for first-time Maryland homebuyers purchasing a principal residence. If the buyer qualifies — they’ve never owned a Maryland principal residence and will occupy this property as their home — the county tax is $0. The $22,000 partial exemption is replaced entirely by this full exemption for qualifying buyers.
Example A
First-Time Buyer, Owner-Occupied
Sale price of $250,000, buyer is a first-time Maryland homebuyer purchasing their primary residence.
County Transfer Tax = $0 (full exemption applies effective 7/1/2025)
Example B
First-Time Buyer, But Not Owner-Occupied
Same buyer pays $250,000 but intends to rent the property out immediately — not owner-occupied.
First-time exemption does NOT apply (not a principal residence)
County Transfer Tax = 1.5% × $250,000 = $3,750
Step 4: State Recordation Tax
In addition to transfer taxes, Maryland charges a state recordation tax when a deed is recorded in Land Records. The rate is $5 per $1,000 of consideration (0.5%), governed by Maryland Tax-Property Article §12-102. This applies to both the deed and any new mortgage or deed of trust being recorded.
The critical difference here is how the base is calculated: for recordation tax, Maryland law requires that the consideration be rounded up to the nearest $500 before calculating the tax. A $300,001 sale becomes $300,500 for recordation purposes.
Example A
Clean $300,000 Sale
Sale price of exactly $300,000 — already a multiple of $500.
Rounded base = $300,000
State Recordation Tax = 0.5% × $300,000 = $1,500
Example B
Sale at $201,200 — Rounding Required
Sale price of $201,200. This is not a multiple of $500, so it rounds up to $201,500.
Rounded base = $201,500
State Recordation Tax = 0.5% × $201,500 = $1,007.50
Baltimore County itself imposes no additional local recordation tax on mortgages — unlike some Maryland counties such as Prince George’s. Only the state rate applies when recording a deed of trust in Baltimore County.
Step 5: Recording Fees and Lien Certificate
Finally, the Baltimore County Circuit Court charges fixed recording fees when documents are filed in Land Records. These are flat fees, not percentages, and they are paid regardless of the property’s sale price.
| Document Type | Fee |
|---|---|
| Deed of Sale (primary residence) | $60 |
| Deed of Trust / Mortgage (owner-occupied home) | $60 |
| Deed of Trust (investment / non-residential) | $115 |
| Releases, Assignments, Other Documents | $115 |
| Lien Certificate (tax clearance, per sale) | $55 |
Example A
Residential Sale with Mortgage
Buyer records a deed and a deed of trust for a primary residence.
Deed recording fee: $60
Deed of Trust recording fee: $60
Lien Certificate: $55
Total fixed fees: $175
Example B
Investment Property Sale
Buyer records a deed and a deed of trust for a non-owner-occupied investment property.
Deed recording fee: $60
Deed of Trust recording fee: $115
Lien Certificate: $55
Total fixed fees: $230
Family and Government Transfer Exemptions
Certain types of transfers are completely exempt from both state and county transfer taxes. These exemptions are built into Maryland Tax-Property Article §12-108 and carried into county law by statute. The calculator zeros out all taxes automatically when any of the following apply:
Spouse and domestic partner transfers: A deed between spouses or registered domestic partners is fully exempt. Close family transfers: Transfers between parents and children, grandparents and grandchildren, siblings, or stepparents and stepchildren are also fully exempt. Government transfers: Any deed to or from the U.S. government, the State of Maryland, or a Maryland political subdivision is exempt. These exemptions exist because no actual arm’s-length sale is taking place, and Maryland law does not impose transfer taxes on non-commercial family or government conveyances.
Putting It All Together: A Full Closing Example
Here is a complete calculation for a typical Baltimore County residential sale, combining all five steps above.
Full Example
$300,000 Owner-Occupied Sale, Standard (Non-First-Time) Buyer
Sale price: $300,000. No assumed debt. Buyer will occupy the home. Buyer has owned Maryland property before. One new mortgage being recorded.
Consideration: $300,000
State Transfer Tax (0.5%): $1,500
County Transfer Tax (1.5% on $278,000 after $22K exemption): $4,170
State Recordation Tax — Deed (0.5%): $1,500
State Recordation Tax — Mortgage (0.5% on loan amount, separately): varies
Deed Recording Fee: $60
Deed of Trust Recording Fee: $60
Lien Certificate: $55
Transfer Taxes Total: $5,670
Fees + Recordation: $1,675 (before mortgage recordation)
How the Calculator Handles Each Scenario
The calculator asks for four key pieces of information: the sale price, any mortgage being assumed, whether the property is a principal residence, and whether the buyer is a first-time Maryland homebuyer. From those inputs it automatically applies the correct rates and exemptions described above.
If a user checks the family transfer or government transfer box, all taxes are set to zero. If first-time buyer is selected but principal residence is not, the calculator shows an error — because the first-time exemption requires owner-occupancy by law. The output breaks down every line item and shows which party (buyer or seller) owes each amount.
Transfer taxes in Maryland are legally negotiable in purchase contracts. The calculator defaults to a 50/50 split as a common convention but lets users specify buyer pays all or seller pays all. Note that the state law overrides any contract language when a first-time buyer is involved — the seller must pay the state’s 0.25% regardless of what the contract says.
