When purchasing a home in Minneapolis or the surrounding Hennepin County suburbs, the “sticker price” is only part of the financial equation. One of the most significant closing costs in Minnesota is the Mortgage Registry Tax (MRT).
While the state sets the base rate, how it is collected and documented at the Hennepin County Government Center can impact your closing timeline. Understanding this tax is essential for budgeting and ensuring your mortgage deed is legally enforceable.
1. What is the Mortgage Registry Tax (MRT)?
The MRT is a state-mandated tax on the privilege of recording a mortgage in Minnesota. It is paid at the time the mortgage is filed with the County Recorder or Registrar of Titles.
Unlike property taxes, which are ongoing, the MRT is a one-time fee due at the start of the loan. In Hennepin County, the revenue is split between the state’s general fund and local environmental and conservation efforts.
2. Calculating the MRT Rate in Hennepin County (2026)
The current rate for the Minnesota Mortgage Registry Tax is 0.0023 (or $2.30 per $1,000) of the principal debt secured by the mortgage.
Quick Calculation Formula
To find your tax, use this simple equation:
$$\text{Debt Amount} \times 0.0023 = \text{MRT Due}$$
3-Column MRT Cost Comparison Table
| Mortgage Loan Amount | Calculation Rate | Total MRT Due |
| $250,000 | 0.0023 | $575.00 |
| $450,000 | 0.0023 | $1,035.00 |
| $750,000 | 0.0023 | $1,725.00 |
3. Mandatory Exemptions and Special Cases
Not every mortgage transaction in Hennepin County requires the full payment of MRT. Minnesota statutes provide specific exemptions that can save homebuyers thousands.
Common MRT Exemptions:
- Mortgage Amendments:
If you are simply changing the terms of an existing mortgage without increasing the principal amount, you may only owe a flat fee rather than the full tax. - Government-Backed Entities:
Certain loans involving state or federal agencies may be exempt under specific Minnesota statutes. - Divorce Decrees:
Mortgages created as part of a marriage dissolution property settlement are often exempt. - Agricultural Land:
Some mortgages on land used primarily for agricultural purposes have a capped or exempt status.
4. How to Pay MRT at the Hennepin County Recorder’s Office
In Hennepin County, the MRT must be paid before the County Recorder will accept the mortgage for filing. Most homebuyers pay this through their title company during the closing process.
Filing Procedures:
- Submit the Mortgage Deed:
The document must clearly state the principal amount of the debt. - Payment Method:
Hennepin County accepts checks, and for professional filers, electronic payments via systems like Tapestry or Laredo. - Verification:
The Recorder’s office will verify the calculation before stamping the document with a “Tax Paid” certification.
5. MRT vs. Deed Tax: Don’t Get Them Confused
Many first-time buyers in Minneapolis confuse MRT with State Deed Tax (SDT).
- MRT: Paid by the Buyer (Borrower) based on the loan amount.
- SDT: Usually paid by the Seller based on the total sale price of the property ($1.65 per $500 in Hennepin County).
6. NLP Insight: The “Multi-County” Mortgage Strategy
If you are purchasing a commercial or large residential property that spans across Hennepin and Ramsey counties (or any other neighboring county), the MRT is not paid twice. You pay the tax in the county where the mortgage is first recorded, and then provide a “Tax Paid” certificate to the second county. This prevents double taxation on a single debt.
Conclusion: Budgeting for Your Hennepin Closing
The Mortgage Registry Tax is a non-negotiable part of the Hennepin County home-buying process. By using the 0.0023 rate, you can accurately predict your costs and avoid surprises at the closing table. Whether you are buying a condo in downtown Minneapolis or a home in Maple Grove, ensuring your MRT is calculated correctly is the final step to securing your property title.

FAQs
Is the Mortgage Registry Tax tax-deductible?
For your primary residence, the MRT is generally considered a “closing cost” and is added to the basis of your home rather than being an immediate tax deduction. However, for investment properties, it may be treated differently. Always consult a CPA.
What happens if the MRT is calculated incorrectly?
If you underpay, the Hennepin County Recorder will reject the filing. This can be disastrous, as it leaves your mortgage “unrecorded,” meaning your lender’s interest in the property is not legally protected against other claims.
Does MRT apply to home equity lines of credit (HELOCs)?
Yes. MRT is due on the maximum principal amount of the HELOC, regardless of how much you actually draw from the line of credit at closing.
Can I pay MRT in installments?
No. The Minnesota Mortgage Registry Tax must be paid in full at the time of recording. There is no provision for installment payments or deferrals.
Does MRT apply to a mortgage refinance in Hennepin County?
Yes, but only on the “New Money.” If you are refinancing your current mortgage in Hennepin County, the MRT is generally only due on the amount that exceeds your remaining principal balance. For example, if you owe $200,000 and refinance for $250,000 (a “cash-out” refinance), you would only pay the 0.0023 tax on the additional $50,000.
Can I get a refund for overpaid Mortgage Registry Tax?
Yes, but the process is rigorous. If an error was made during recording at the Hennepin County Government Center, you must file a claim for a refund with the Minnesota Commissioner of Revenue. This claim must typically be filed within 3.5 years from the date the tax was paid. It is highly recommended to have your title company verify all calculations before the final recording to avoid this lengthy process.
