You bought a house. What is deductible now, and what everyone gets wrong.

The short version

• The most common homeowner disappointment: the mortgage interest deduction does nothing for most people, because the standard deduction is larger than everything they can itemize.
• It only pays once your itemized total clears that bar. Until then, the deduction exists and is worth zero.
• Your closing statement contains one item people miss almost every time, and it is deductible in full in the year you bought.
• Nothing here applies to a rental or a home office. Those are a different set of rules and a much better one.

The number that decides whether any of this matters

Every year you choose between two options: take the standard deduction, a flat amount requiring no records, or itemize your actual deductible expenses. You take whichever is larger. You cannot take both.

For a married couple filing jointly, the standard deduction is now above thirty thousand dollars. That is the bar. Your mortgage interest, property tax, state taxes, charitable giving and a few other items are added up, and only if the total clears that bar does itemizing produce anything at all.

Here is why so many new homeowners are disappointed. Say a couple pays eighteen thousand of mortgage interest and eight thousand of property tax. Twenty six thousand of very real housing cost, and it is still less than the standard deduction they would have received for doing absolutely nothing. Their tax benefit from buying a house is zero.

This is not a mistake anyone made. It is how the law has worked since the standard deduction was roughly doubled. But it is not what the mortgage broker implied, and it is worth knowing before you count on money that is not coming.

When it does work: larger mortgages, higher rate environments, expensive property tax states, and households that also give meaningfully to charity. Those are the profiles where itemizing wins, sometimes by a lot.

What counts if you do clear the bar

Mortgage interest, on debt used to buy, build or substantially improve your main home, within the limits on total mortgage balance. Your lender sends a Form 1098 with the figure.

Property taxes, but here is the catch: property tax is grouped with state and local income or sales taxes into one combined cap. That cap was raised meaningfully for 2026 and is far more generous than it was, but it is still a cap, and in high tax states it still binds.

Mortgage points, and this is the one people miss. If you paid points to lower your rate on a purchase, they are generally deductible in full in the year you bought, not spread across the loan. Points on a refinance work differently and get spread out. Purchase points are the friendly version, and they sit on your closing statement where nobody looks again.

Mortgage insurance, depending on the year and your income. Worth checking rather than assuming.

What does not count, no matter how much it costs

Homeowners insurance. HOA fees. Utilities. Repairs and maintenance. General improvements. Title insurance. Appraisal fees. Most of your closing costs. The down payment itself, obviously, though people do ask.

Improvements are not deductible, but keep every receipt anyway. Improvements increase your basis in the house, which reduces your taxable gain when you eventually sell. A kitchen remodel does nothing for you this year and may quietly save you real money in fifteen years. That folder is worth starting on day one, because reconstructing it later is close to impossible.

Dig out the closing statement before you file

Your settlement statement is the most useful document in the whole transaction and most people file it away and never look at it again.

It contains the points you paid, property tax that was prorated between you and the seller at closing, and prepaid interest for the partial first month. All three are deductible items that will not appear on any form your lender sends you in January. If your preparer never asks for the closing statement, that is worth noticing.

The two situations where the rules get much better

A home office, if you are self employed or run a business from the house. This one is not subject to the itemizing question at all. It is a business deduction, it works whether or not you itemize, and it lets a portion of utilities, insurance and repairs become deductible, which they never are for a normal homeowner. It requires a space used regularly and exclusively for the business. Employees working from home for someone else do not currently qualify.

A rental, or a room you rent out. Once part of the property produces income, the entire framework changes. Depreciation enters, expenses become deductible against the rent, and the arithmetic gets considerably more interesting.

If either applies to you, the advice in this article is largely beside the point, and you should be having a different conversation.

What to do this month

1. Find the closing statement and put it with your tax documents now, while you know where it is.
2. Start the improvement receipts folder. Digital is fine. Any folder is better than the drawer.
3. Add up your likely mortgage interest, property tax and charitable giving. If the total is comfortably below the standard deduction, stop planning around deductions and stop worrying about it. That is a legitimate and freeing answer.
4. If you work from home for your own business, ask about the home office deduction specifically. It is the one that pays regardless.

Buying a house is a good financial decision for plenty of reasons. For most buyers, the tax deduction is not one of them, and knowing that early is better than discovering it in April.
