Inherited House Taxes: What You Owe and How to Reduce the Bill

The property tax bill still shows your parent's name, the county wants payment by the 15th, and you're wondering whether the IRS expects a cut of the house itself. Taxes on inherited real estate trip up more families than almost anything else in the estate process — partly because the rules are genuinely complicated, and partly because outdated advice keeps circulating online.

Here's what actually applies.

The Stepped-Up Basis Changes Everything

When you inherit a house, the IRS resets your cost basis to the property's fair market value on the date your loved one died. This is the "stepped-up basis" under IRC § 1014, and it's the single biggest tax advantage of inherited real estate.

Your parent bought the house in 1985 for $80,000. On their date of death it was worth $350,000. Your basis is $350,000 — not $80,000. If you sell for $355,000, your taxable capital gain is only $5,000, not $275,000.

To document the stepped-up basis, get a date-of-death appraisal from a qualified appraiser. This costs $300–$600 and is the single best investment you'll make during the entire estate process. An automated estimate can be a starting point, but it is not a substitute for a retrospective appraisal with documented methods and historical comparable sales if the value is questioned.

Capital Gains Tax on an Inherited House

You only owe capital gains tax on appreciation that occurs after the date of death. The math is straightforward:

Sale price − date-of-death fair market value − selling expenses = taxable gain (or loss)

If the number is negative, whether the loss is deductible depends on how the estate or heir held and used the property; a loss on a personal-use home generally isn't deductible. A deductible net capital loss may be subject to the $3,000 annual limit, with the rest carried forward. If the number is positive, the gain is generally treated as long-term regardless of how soon you sell.

One common mistake: treating improvements you paid for during probate as part of the basis. You can add capital improvements (a new roof, HVAC replacement) to your basis, which reduces the taxable gain. Keep every receipt.

Federal Estate Tax Thresholds

Most families don't owe federal estate tax. For a U.S. citizen or resident who dies in 2026, Form 706 is generally required if the gross estate plus adjusted taxable gifts and specific exemption exceeds $15 million. An executor may also file Form 706 to elect portability of a deceased spouse's unused exclusion, regardless of estate size.

Some states have their own estate or inheritance tax with lower thresholds. Five states currently impose an inheritance tax: Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. Iowa's inheritance tax does not apply to estates of people who die on or after January 1, 2025. The rates and exemptions vary by your relationship to the deceased (spouses and children typically pay lower rates or nothing).

Property Taxes Don't Pause

While you sort out probate and decide what to do with the house, property taxes keep accruing. The county doesn't care whether the estate is settled — the bill is attached to the property, not the owner. If nobody pays, a tax lien attaches to the house and compounds with penalties.

In some states, the property tax assessment resets when ownership transfers. California's Proposition 19 (effective February 2021) significantly limited the parent-to-child property tax exclusion. Other states reassess at transfer too. Check your county assessor's rules within the first month.

If cash is tight during probate, some counties offer payment plans or hardship deferrals. Ask the county tax office which options are available and apply early; these programs may require documentation that takes weeks to process.

How to Minimize the Tax Bite

Sell within the first year. The closer the sale price is to the date-of-death value, the smaller the gain. Market shifts over two or three years can create a taxable gap that didn't need to exist.

Document everything. Capital improvements, selling costs (agent commissions, staging, legal fees), and estate administration expenses can all reduce the taxable amount. A shoebox of receipts now saves real money at filing time.

File the right returns. The estate may need to file IRS Form 1041 for post-death income, such as rental income. A domestic estate generally must file if gross income is $600 or more, if it has a nonresident-alien beneficiary, or if another filing requirement applies. Your personal return reports the gain or loss when you sell property distributed to you.

Consult a CPA if the estate is complex. Foreign property, multiple beneficiaries, rental history, or an estate near the federal threshold all warrant professional help. The cost of an estate CPA ($500–$2,000) is usually a fraction of the tax mistakes they prevent.

Where Inherited House Taxes Fit in the Bigger Picture

Tax decisions don't happen in isolation — they connect to whether you sell, keep, or rent the property, how you handle the mortgage, and how you divide proceeds among siblings. The Selling or Keeping the Family Home guide walks through the full decision framework, including a carrying-cost projector and stepped-up basis worksheet so you can run the numbers for your specific situation.

In the UK, the probate value is generally used for Capital Gains Tax purposes. The basic Inheritance Tax nil-rate band is £325,000; a qualifying residence passed to direct descendants may add a residence nil-rate band of up to £175,000, subject to conditions and taper. Canada has no inheritance tax but generally treats death as a deemed disposition at fair market value, which can create a capital gain on the final return unless a rollover or exemption applies. Australia abolished inheritance tax in 1979, but capital gains tax can apply when a beneficiary sells, subject to inherited-home exemptions.

Whatever your jurisdiction, the principle is the same: document the value at death, understand what triggers tax, and sell or transfer before market drift creates an unnecessary bill.
