Millions of homeowners who could not scrape together a 20 percent down payment are quietly paying an extra $100 to $250 a month in private mortgage insurance. For years, Congress offered a partial remedy: a federal tax deduction for those premiums. Then it let the provision expire. Then it renewed it retroactively. Then it expired again. The cycle repeated so many times that most tax preparers stopped counting on it.
That cycle is finally over. Legislation signed into law in 2025 made the PMI deduction permanent starting with the 2026 tax year, and qualifying homeowners stand to save several hundred dollars annually. Here is what changed, who benefits, and what to check before you file.
The law that made it permanent
The provision is part of H.R. 1 of the 119th Congress, the sweeping reconciliation package commonly known as the “One Big Beautiful Bill.” Among its many tax provisions, the law amended Section 163 of the Internal Revenue Code to treat qualified mortgage insurance premiums as deductible mortgage interest on a permanent basis, with no sunset date. The full text of the enrolled bill is available on Congress.gov.
The backstory matters because it explains why so many homeowners missed this deduction in the past. Congress first created it in 2006 as a temporary measure. Over the next 15-plus years, lawmakers let it lapse and then retroactively renewed it multiple times, sometimes months after the filing deadline had passed. That left taxpayers, tax preparers, and mortgage servicers guessing whether the deduction would exist in any given year. Now it is written into the code permanently.
Who qualifies and how much you can save
The deduction covers premiums on qualified mortgage insurance tied to debt used to buy, build, or substantially improve a primary or secondary residence. That includes conventional PMI from private insurers and FHA mortgage insurance premiums (MIP). The underlying mortgage must have originated after December 31, 2006, which effectively covers nearly every active home loan today.
To claim the deduction, you must itemize your federal return. The benefit phases out for filers with adjusted gross income above $100,000 (or $50,000 if married filing separately) and disappears entirely at $109,000 ($54,500 for MFS). Those thresholds are not indexed for inflation, which means they have not budged since the deduction was first created in 2006.
How much you actually save depends on your annual premium and your marginal tax rate. A few examples:
- A homeowner paying $1,500 a year in PMI in the 22 percent bracket would cut roughly $330 from their federal tax bill.
- Someone in the 24 percent bracket paying $2,000 annually would save about $480.
- A borrower in the 12 percent bracket paying $1,200 a year would see a more modest $144 reduction.
These are not enormous windfalls, but for households that stretched to buy a home, a few hundred dollars back at tax time is real money.
One important caveat: the deduction only helps if you itemize, and the standard deduction remains high. Under the reconciliation law’s extension of 2017 Tax Cuts and Jobs Act provisions, the standard deduction for 2026 is projected to be approximately $15,000 for single filers and $30,000 for married couples filing jointly. If your total itemized deductions, including mortgage interest, PMI, state and local taxes (still capped at $10,000), and charitable contributions, do not clear that bar, this provision will not reduce your tax bill. Homeowners with smaller mortgages or in states with low property taxes may find that itemizing still does not pencil out.
How to claim it on your return
The mechanics are straightforward. Your mortgage servicer will report your deductible PMI or MIP amount in Box 5 of Form 1098, the same document that shows your mortgage interest paid. You then include that figure on Schedule A when you file.
One wrinkle to watch for: if you prepaid your mortgage insurance in a lump sum at closing, the IRS requires you to spread that cost over the expected life of the loan rather than deducting it all in one year. This commonly applies to borrowers who paid upfront MIP on an FHA loan or opted for a single-premium PMI policy at closing. Tax software generally handles the allocation automatically, but it is worth flagging for your preparer if you went that route.
Borrowers who refinanced should also take note. If your refinanced mortgage is secured by a qualified residence and you are paying PMI or MIP on the new loan, those premiums generally qualify under the same rules. The key requirement is that the debt was used to acquire, build, or substantially improve the home.
The IRS has begun updating its guidance to reflect the permanent change. Publication 505 is expected to confirm the deduction’s permanent status for tax year 2026. Filers should check the most current version before preparing their returns, as the IRS may still be finalizing language as of mid-2026.
What remains unresolved
Several questions are still open heading into the 2026 filing season.
No standalone revenue estimate has been published for the PMI provision. The Joint Committee on Taxation scored the broader reconciliation bill, but the cost of making this single deduction permanent has not been broken out publicly. That makes it harder to gauge how many taxpayers the provision is expected to reach.
State tax treatment is also unsettled. Some states automatically conform to federal itemized deductions, meaning residents there will see a state-level benefit with no additional legislation. Other states decouple from federal rules and set their own deduction schedules. Whether you get a state tax break depends on where you live and how your state legislature responds. As of June 2026, no comprehensive state-by-state analysis has been published.
There is also an open question about whether a permanent deduction will encourage more buyers to choose low-down-payment mortgages. If PMI costs less on an after-tax basis, the financial penalty for putting down less than 20 percent shrinks. But the tax savings are relatively small compared to the total cost of PMI over the life of a loan, and it is unclear whether they are large enough to shift borrowing behavior, particularly for households in the $75,000 to $125,000 AGI range where the full deduction is available. That question will not have a data-driven answer until 2027 filing statistics come in.
How this fits into your home-buying math
The permanent deduction removes a genuine source of uncertainty, but it does not change the calculus for every buyer. PMI still costs money. The deduction offsets only a fraction of that expense, and only for borrowers who itemize and earn below the AGI threshold.
If you are weighing whether to put 10 percent down and accept PMI versus waiting to save a full 20 percent, the deduction is one variable worth modeling, not the deciding factor. Run the numbers with your lender or tax advisor. Compare the after-tax cost of PMI against the opportunity cost of tying up more cash in a down payment, and remember that PMI on conventional loans can be canceled once your loan-to-value ratio drops below 80 percent.
For homeowners already paying PMI and already itemizing, this is straightforward found money. When your Form 1098 arrives in January 2027, check Box 5 and make sure your return reflects it.
