To calculate mortgage recording tax, multiply your loan’s principal amount by the rate your state or locality charges for recorded mortgages, apply the jurisdiction’s rounding rule, then subtract any credits or exemptions you qualify for. Rates run from roughly 0.02% to nearly 3%, so the same $400,000 loan could produce a bill of a few hundred dollars in one state or more than $10,000 in another. Before you run the numbers, confirm the tax exists where your property sits: only about seven states impose it.
Check Whether Your State Charges the Tax
Most states do not levy a separate tax on recording a mortgage. The ones that do are Alabama, Florida, Kansas, Minnesota, New York, Oklahoma, and Tennessee. A handful of other states charge recordation or deed taxes that work similarly but go by different names and may apply to the secured debt rather than the property transfer.
If your property is in a state without this tax, you’ll still pay a flat recording fee to the county for filing the mortgage document, but there is no percentage calculation to run on the loan amount. If your state is on the list, keep going.
Rates vary widely. New York produces the highest bills because the state stacks a basic tax, an additional tax, and a special additional tax on top of county-level charges, pushing combined rates above 2% in some counties. Florida charges a flat 2 mills (0.2%) statewide. Alabama is 0.15% and Tennessee is 0.115%. Oklahoma’s rate depends on the loan term and tops out at 0.10%.
Find the Exact Rate for Your Property
Rates are set at the state level and can include extra layers imposed by a county or city. The county clerk’s office or recorder of deeds in the jurisdiction where the property sits maintains the current schedule, and many post their rate tables online. Ask for the rate expressed either as a dollar amount per $100 of debt or as a percentage of the principal, since offices use both conventions.
You can also read the tax off two standard federal disclosure forms. The Loan Estimate, which your lender must provide within three business days of receiving your application, shows a preliminary figure. The Closing Disclosure, delivered at least three business days before closing, shows the final amount.1eCFR. 12 CFR 1026.38 – Content of Disclosures for Certain Mortgage Transactions Both list mortgage recording tax under the “Taxes and Other Government Fees” subheading inside the “Other Costs” section.
Run the Calculation
The core formula is straightforward: principal loan amount multiplied by the applicable rate. A $350,000 loan at a combined rate of 1.05% produces $3,675. That is the whole calculation when no rounding rules or exemptions apply.
Rounding is where people trip. Many jurisdictions require you to round the debt to the nearest $100 before applying the rate, and the direction of rounding varies. Some round up any fraction, so $350,050 becomes $350,100. Others use standard rounding, where $350,049 goes down to $350,000 and $350,051 goes up to $350,100. The dollar difference is usually small, but recording offices will reject a filing that is short by even a dollar, so match the local convention exactly.
Once you have the initial product, subtract any credits or exemptions. Some jurisdictions grant a fixed-dollar credit for residential properties. A $30 credit on a one- or two-family home would reduce the $3,675 above to $3,645. Others exempt the first slice of debt from one layer of the tax rather than from all layers, which takes a longer calculation: compute the tax on the full amount for the layers without the exemption, compute the tax on the reduced amount for the layer that has one, then add the results.
Worked Example
Say you’re borrowing $500,000 in a jurisdiction with a combined rate of 1.05% and a $30 residential credit, and the local rule is to round to the nearest $100.
- Loan amount after rounding: $500,000 (already a round number)
- Tax before credits: $500,000 × 0.0105 = $5,250
- Residential credit: −$30
- Total mortgage recording tax due: $5,220
That $5,220 needs to be ready at the closing table. If the loan were $500,075, rounding up to $500,100 would raise the pre-credit tax to $5,251.05. The recording office will expect the exact figure after the local rounding rules are applied.
Credits and Exemptions That Change the Number
The most common exemption keys on property type. Jurisdictions that impose this tax frequently offer a partial break for one- or two-family residences, either by exempting a slice of the debt from one layer of the tax or by applying a flat credit. The break rarely eliminates the tax, but it can shave several hundred dollars off a large mortgage.
Credit unions get broader protection. Federal law exempts federally chartered credit unions from most state and local taxes, and many states extend the same treatment to state-chartered credit unions. When a credit union is your lender, some or all of the mortgage recording tax layers may not apply. The credit union’s closing department will know whether the exemption covers the full tax or only certain components.
Nonprofit lenders and government-backed loan programs sometimes qualify for waivers, though the rules vary. If you think an exemption applies, ask your closing attorney or title company to confirm before the Closing Disclosure is finalized. Recovering an exemption after you’ve already paid is much harder than claiming it upfront.
Refinances Can Cut the Tax Down
A refinance normally triggers a new mortgage recording tax because you are recording a new lien. Refinancing a $400,000 balance into a $450,000 loan would ordinarily produce tax on the full $450,000, even though most of that money is replacing debt you already paid tax on.
Some states offer a workaround. The best-known version is the Consolidation, Extension, and Modification Agreement, where the new lender takes an assignment of the existing mortgage instead of paying it off. The old mortgage is consolidated with the new one, and you pay recording tax only on the additional amount above your prior balance. On that same $400,000-to-$450,000 refinance, you would owe tax on $50,000 rather than $450,000. In a high-rate jurisdiction, the savings can run into the thousands. Not every lender participates and there are eligibility restrictions, so raise it early.
If no assignment mechanism is available in your state, the tax hits the full new loan amount. Build that cost into your break-even math when deciding whether to refinance at all.
Don’t Confuse This With Transfer Tax
Mortgage recording tax and transfer tax show up on the same closing statement and get mixed up often. Mortgage recording tax is based on the loan principal. Transfer tax (sometimes called a deed tax or stamp tax) is based on the sale price or assessed value of the property. You can owe one without the other. A cash buyer pays no mortgage recording tax because there is no loan to record, but still pays transfer tax on the purchase. A borrower refinancing pays mortgage recording tax on the new lien but owes no transfer tax because no property is changing hands.
Both taxes appear under “Taxes and Other Government Fees” on your Closing Disclosure, so check the line items carefully when you verify your calculation. The mortgage recording tax line will reference the loan amount; the transfer tax line will reference the sale price.
