We're about to sell our former home. It's been a rental since 2017. I've been filling out a set of 2023 tax forms like a mock 2024 tax filing so I know what to expect come tax time. It looks like Form 4797 - Sales of Business Property is where we account for the sale of the rental. The rental is a Section 1250 asset so it goes in Part III. Line 21 appears to be where we account for "Cost or other basis plus expense of sale."
Is that really it? One figure on one line is all the IRS wants to see for my basis calculation, which includes initial cost basis and purchasing costs, improvements prior to being converted to a rental, and sale costs? I guess I'm just surprised that I'm going to put a figure there and that's all she wrote. Obviously if they audit us we'll have to show all the paperwork backing up the calculation but I guess I thought there would be more? To anyone that has sold investment RE before, does this sound right?
