(Publication 551) – It’s a Good Business, This Inheriting Thing

When you inherit property—be it real estate, stocks, or other valuable assets—you’re not just stepping into ownership. You’re also stepping into a new tax situation that can have serious consequences when it’s time to sell. Understanding your tax basis is key to avoiding surprise capital gains and ensuring your records are correct.

Step-Up in Basis: The Inheritance Advantage

Under IRS rules (see Publication 551), the general rule for inherited property is that its tax basis is stepped up (or down) to the fair market value (FMV) on the date of the decedent’s death.

• If your parent bought a home for $100,000 and it was worth $500,000 at death, your basis is $500,000.
• If you later sell it for $520,000, your taxable gain is only $20,000—not $420,000.

This “step-up” rule often means heirs pay little or no capital gains tax when they quickly sell inherited assets, making inheritance one of the most tax-efficient transfers of wealth.

Alternate Valuation and Community Property Nuances

The estate’s executor may elect an alternate valuation date—six months after the date of death—if it reduces both the estate’s value and estate taxes. If you’re in a community property state like Texas, both halves of the community property generally receive a full step-up in basis, not just the decedent’s portion.

What About Depreciable Property?

If you inherit rental or business property, your new stepped-up basis becomes the starting point for future depreciation deductions. This means you can continue to enjoy tax advantages from property that may already have been fully depreciated by the original owner.

Recordkeeping and Valuation

It’s critical to keep records showing how the basis was determined:

• Estate appraisals
• FMV statements
• Correspondence with executors or accountants

The IRS expects consistency between the estate’s reported value and your eventual sale basis. (Publication 551 and Form 8971 guide this reporting alignment.)

Bottom Line

When you inherit property, your tax basis usually gets a fresh start at fair market value—one of the most favorable rules in the tax code. Whether you sell or keep it, knowing your correct basis protects you from overstating gain or underclaiming depreciation.

Inheritance may not be a business, but when it comes to tax efficiency—it’s certainly a good one.
