Hello badams2011, I hope your day is going well.
When you inherit property, you receive what is called "stepped up basis". This means your cost basis (what you paid for the home) is the fair market value of the home on the date of death. I advise to get an appraisal of home as soon as you can. The longer we wait to figure stepped up basis, the harder to get the information. You will only pay taxes on the appreciation (growth in value) of the home from the date of death.

When home is sold, if you do have a gain, you can pay estimated taxes on the gain to the IRS. Or you can pay when you file your tax return. I advise to make estimated payments if you can, this will help avoid any late pay penalty or interest for paying late.
