To qualify for and apply for a mortgage credit certificate, you work with a lender approved by your state or local housing finance agency, meet the agency’s first-time buyer, income, and purchase-price rules, and submit the application before your home loan closes. The certificate then gives you a federal tax credit each year equal to a set percentage of the mortgage interest you pay, for as long as the home is your primary residence.
Who Qualifies
First-Time Buyer Rule
You generally must be a first-time homebuyer, which means you (and your spouse, if married) have not held an ownership interest in a principal residence during the three years before the purchase.1Office of the Law Revision Counsel. 26 USC 25 – Interest on Certain Home Mortgages This looks at legal title, not just whose name was on the mortgage, so co-ownership with a relative or an ex-spouse within that window disqualifies you.
There is an exception. If you buy in a federally designated targeted area, the first-time buyer requirement is waived. Targeted areas are census tracts where median family income falls below a set threshold or where at least 70 percent of families earn below 80 percent of the statewide median income. Your housing finance agency can tell you which tracts in your market qualify.
Income Limits
Your household income must fall below the ceiling set by your local housing finance agency, which is based on area median income for your county or metro. Larger households usually get higher ceilings. The calculation typically counts all adults aged 18 and older who will live in the home, not just the people signing the loan.
Purchase Price Cap
The home’s price must also come in under a maximum. Federal rules use safe-harbor average area purchase prices the IRS publishes each year. For non-targeted areas, the limit is 90 percent of the average area purchase price; for targeted areas, it is 110 percent. IRS Revenue Procedure 2025-18, effective April 2025, set the national average purchase price at $540,700 and derived local limits from FHA single-family loan limits. Your agency applies those figures to your specific location, so the cap varies by county.
Primary Residence Only
The property must be your primary residence. Investment properties, vacation homes, and second residences do not qualify.2FDIC. Mortgage Tax Credit Certificate (MCC)
Documents to Gather
The paperwork mostly overlaps with a standard mortgage file, but the housing finance agency reviews it on its own. Have these ready:
- Federal tax returns, typically for the last three years, which verify both your first-time buyer status and your income history.
- Proof of current income: W-2s from the previous two years and pay stubs covering at least 30 days. Self-employed applicants usually need year-to-date profit-and-loss statements and IRS tax transcripts.
- Household occupancy details, including the number and ages of everyone who will live in the home.
- Property information: legal description, address, and purchase price.
- Loan details: final loan amount, interest rate, and loan type.
Missing documents are the most common source of delay, so complete the file before it reaches underwriting.
How to Apply
You cannot apply on your own. The process runs through a lender approved by your state or local housing finance agency.
- Find your housing finance agency. Every state has one. The National Council of State Housing Agencies keeps a directory at ncsha.org.3National Council of State Housing Agencies. Find a State Housing Finance Agency
- Choose a participating lender. Your agency publishes a list of lenders approved to originate MCC-eligible loans. Not every mortgage lender participates, so check the list before you get deep into the process with one who cannot help.
- Apply before closing. The application must be submitted while your loan is still in underwriting. You cannot get a certificate after the loan has closed and funded.
- Wait for agency review. Turnaround varies with volume, from a few days to a couple of weeks.
- Receive a conditional commitment. If approved, the agency issues a commitment tied to your closing.
- Get the final certificate. After closing and recording of the deed, the agency issues your permanent MCC. Keep it for the life of the loan.
Application fees vary by program but generally run several hundred dollars, sometimes split between a lender processing fee and an agency application fee. Ask your lender for the exact figures upfront.
MCCs work with most first mortgage loan types, including FHA, VA, USDA Rural Housing, and conventional loans.2FDIC. Mortgage Tax Credit Certificate (MCC) Some state agencies also let you combine the MCC with their own down payment assistance, which is worth asking about when you apply.
What the Certificate Is Worth
Each certificate specifies a credit rate set by the issuing agency somewhere between 10 and 50 percent. Your annual credit equals that rate times the mortgage interest you paid during the year. At a 25 percent rate on $12,000 of interest, the credit is $3,000, applied directly against the federal income tax you owe.
One cap applies. If your certificate rate is above 20 percent, the credit tops out at $2,000 per year no matter how much interest you paid.1Office of the Law Revision Counsel. 26 USC 25 – Interest on Certain Home Mortgages At 20 percent or below, there is no dollar cap.
Interest claimed as a credit cannot also be deducted. Federal regulations require you to reduce your Schedule A mortgage interest deduction by the credit amount.4eCFR. 26 CFR 1.163-6T – Reduction of Deduction Where Section 25 Credit Taken So on $12,000 of interest with a $2,000 credit, you can still deduct up to $10,000 on Schedule A. If you take the standard deduction, the credit still works on its own because it reduces tax liability directly.
The certificate also affects qualification. Lenders underwriting MCC-eligible loans factor the expected credit into your debt-to-income ratio. Fannie Mae’s guidelines have lenders calculate the monthly benefit as the mortgage amount times the note rate times the MCC percentage, divided by 12, and add that result to your qualifying income.5Fannie Mae. Mortgage Credit Certificates For buyers near the edge of affordability, that added income can be the difference between approval and denial.
Claiming the Credit Each Year
You claim the credit by filing IRS Form 8396 with your federal return.6Internal Revenue Service. About Form 8396, Mortgage Interest Credit The form walks through the calculation: enter the interest paid, multiply by your certificate credit rate, and apply the $2,000 cap if your rate is above 20 percent.7Internal Revenue Service. Form 8396, Mortgage Interest Credit
If the credit is larger than your tax liability, you do not lose the unused portion. You can carry the excess forward for up to three years.8eCFR. 26 CFR 1.25-2T – Amount of Credit (Temporary) Any amount above the $2,000 cap, however, cannot be carried forward; only credit within your allowed amount but above your liability rolls over. The credit continues each year the home is your primary residence and the mortgage carries a balance, and you file Form 8396 for each of those years.
Things That Can Change or Undo the Benefit
Refinancing
Refinancing does not automatically end the certificate, but it does require a step. The original MCC is tied to the original loan, so when that loan is paid off, the certificate technically expires. To keep the benefit, apply for a reissued MCC from the same agency that issued the original.9Office of the Law Revision Counsel. 26 USC 25 – Interest on Certain Home Mortgages – Section: Reissuance of Mortgage Credit Certificates The reissued certificate replaces the original entirely, and the new credit for any remaining year cannot exceed what you would have received under the original. If you refinance into a longer term, the reissued MCC still expires on the original loan’s maturity date. Contact your agency early in the refinance process so this does not fall through the cracks.
Selling Within Nine Years
If you sell within nine years of the purchase, you may owe a recapture tax that claws back part of the federal subsidy. Recapture applies only when all three conditions are met: you sell within nine years, you have a gain on the sale, and your income has risen since you bought.2FDIC. Mortgage Tax Credit Certificate (MCC) If your income at sale is still below the federal qualifying limit, the recapture is zero regardless of timing or gain. The tax can never exceed 50 percent of your gain, and it disappears entirely if you sell after nine full years or if the sale results from the owner’s death.10Office of the Law Revision Counsel. 26 USC 143 – Mortgage Revenue Bonds – Section: Recapture of Portion of Federal Subsidy Any recapture is reported on IRS Form 8828 with your return for the year of the sale.11Internal Revenue Service. Instructions for Form 8828, Recapture of Federal Mortgage Subsidy For most holders who stay several years and whose income has not dramatically outpaced local limits, the amount is modest or zero, but you should know it exists before you commit.
False Statements on the Application
Federal law imposes specific penalties for material misstatements on MCC applications made under oath. A misstatement caused by negligence carries a $1,000 penalty per certificate. A fraudulent one carries $10,000 per certificate, on top of any criminal penalties.12Office of the Law Revision Counsel. 26 USC 6709 – Penalties With Respect to Mortgage Credit Certificates The penalties target whoever made the false statement, which can include the borrower. Be accurate about income, household size, and homeownership history.
