Dear Liz: My mother gave her house to my brother and me in 2011 by quitclaim deed. My brother lived in the house with her until she passed in 2018, and he continues to live there. He wants to buy my half of the home, and I am wondering what my taxes may be because I am not purchasing another home with my proceeds. Since this was a gift, do these things apply? The home is valued at $500,000 so my half is worth $250,000.

Answer: Your tax bill will be based on what your mother paid for the home originally, plus any qualifying home improvements she made over the years. That is what’s known as the home’s tax basis, and it will be subtracted from the sale proceeds to determine your potentially taxable capital gain.

Let’s say your mother originally paid $100,000 for the house and remodeled the kitchen for $50,000, for a total basis of $150,000. When she gave you and your brother the house, you each received half of that basis, or $75,000. If your brother pays you $250,000, you would subtract $75,000 from those proceeds for a capital gain of $175,000.

The federal tax rate on capital gains ranges from 0% to 20% based on income, but most people pay 15%. If your state and city assess capital gains or other taxes, you’d owe those as well.

You don’t qualify for the home sale exclusion that allows many home sellers to avoid taxation on home sale profits up to $250,000. To get the exclusion, you must own and live in the home at least two of the previous five years.

It doesn’t matter that you don’t plan to buy another home; the tax law that allowed people to roll home sale profits into another home went away decades ago.

Your tax bill might have been substantially reduced if your mother had bequeathed the home to you and your brother, rather than giving it before her death. If she’d left it to you in a will or living trust, at her death the tax basis would have been “stepped up” to the home’s current fair market value.

If the home was worth $450,000 at her death, for example, you and your brother would have a tax basis of $225,000 each. If he paid you $250,000, your taxable gain would have been just $25,000.

You might be able to spread out the tax bill if your brother is willing to pay you over time rather than buy you out all at once, said Mark Luscombe, principal analyst for Wolters Kluwer Tax & Accounting.

That would be one of several issues you should discuss with a tax pro before proceeding. A big capital gain can affect other aspects of your taxes and may require you to make estimated quarterly payments to avoid penalties for underpayment. A tax pro can advise you about what to expect and how to pay what you owe.
