Dear Liz: I have sold my family home recently after almost 50 years. I had done lots of improvements throughout those years. Due to a fire 15 years ago, all the documentation for these improvements has been destroyed. How do I document the improvements for the capital gains tax calculation?
Answer: As you probably know, you can exclude $250,000 of capital gains from the sale of a principal residence as long as you own and live in the home at least two of the previous five years. The exclusion is $500,000 for a couple.
Once upon a time, that meant few homeowners had to worry about capital gains taxes on the sale of their home. But the exclusion amounts haven’t changed since they were created in 1997, even as home values have soared. Qualifying home improvements can be used to increase your tax basis in the home and thus decrease your tax bill, but the IRS probably will demand proof of those changes should you be audited.
You could ask any contractors you used who are still in business if they will provide written verification of the work they performed, suggests Mark Luscombe, principal analyst for Wolters Kluwer Tax & Accounting. You also could check your home’s history with your property tax assessor to see if its assessment was adjusted to reflect any of the improvements.
At a minimum, prepare a list from memory of the improvements you made, including the year and the approximate cost. If you don’t have pictures of the house reflecting the changes, perhaps friends and relatives might. This won’t be the best evidence, Luscombe concedes, but it might get the IRS to accept at least some increase in your tax basis.
If you’re a widow or widower, there’s another tax break you should know about. At least part of your home would have gotten a step-up in tax basis if you were married and your co-owner spouse died. In most states, the half owned by the deceased spouse would get a new tax basis reflecting the home’s current market value. In community property states such as California, both halves of the house get this step-up. A tax pro can provide more details.
Other homeowners should take note of the importance of keeping good digital records. While documents may not be lost in a fire, they may be misplaced, accidentally discarded or (in the case of receipts) so faded they’re illegible. To make sure documents are available when you need them, consider scanning or taking photographs of your records and keeping multiple copies, such as one set in your computer and another in a secure cloud account.
