The Cost Basis Never Stepped Up The way the tax code works, if a spouse passes, the deceased’s share in the cost basis in those shares is stepped up to the value on the date of death.
When a married person dies and passes assets outright or in a qualifying trust for the surviving spouse, those assets receive a new basis (hopefully a step-up instead of a reduced basis) but, due to an unlimited marital deduction, are not subject to estate tax.

Can a house be put on a step up in basis?
Yes and no. If the asset was held in a revocable (or living) trust before the owner died, it will likely be eligible for a step-up in cost basis. Financial accounts aren’t the only assets that can be held in trust. A house can be put in trust and other types of real property as well.
How does a surviving spouse change the basis of a property?
Basis. As the surviving spouse, your basis in property you owned with your spouse as a qualified joint interest is the cost of your half of the property with certain adjustments. Decrease the cost by any deductions allowed to you for depreciation and depletion. Increase the reduced cost by your basis in the half you inherited.
