I lived in a home as my principal residence for the first 2 of the last 5 years. For the last 3 years, the home was a rental property before selling it. Can I still avoid the capital gains tax and, if so, how should I deal with the depreciation I took while it was rented out?

If, during the 5-year period ending on the date of sale, you owned the home for at least 2 years and lived in it as your main home for at least 2 years, you can exclude up to $250,000 of the gain ($500,000 on a joint return in most cases). However, you cannot exclude the portion of the gain equal to depreciation allowed or allowable for periods after May 6, 1997. This gain is reported on Form 4797. If you can show by adequate records or other evidence that the depreciation allowed was less than the amount allowable, the amount you cannot exclude is the amount allowed. Refer to Publication 523 , Selling Your Main Home and Form 4797 (PDF), Sale of Business Property for specifics on calculating and reporting the amount of the eligible exclusion.

I have a home office. Can I deduct expenses like mortgage, utilities, etc., but not deduct depreciation so that when I sell this house, the basis won't be affected?

If you qualify to deduct expenses for the business use of your home, you can claim depreciation for the part of your home that is a home office. Generally, the part of your home that is a home office is depreciated over a recovery period of 39 years using the straight line method of depreciatiion and a mid-month convention. If you do not claim depreciation on that part of your home that is a home office, you are still required to reduce the basis of your home for the allowable depreciation of that part of your home that is a home office when reporting the sale of your home. For more information, refer to Publication 587, Business Use of Your Home.

What form(s) do we need to fill out to report the sale of rental property?

The gain or loss on the sale of rental property is reported on Form 4797 (PDF), Sale of Business Property. Form 1040, Schedule D (PDF), Capital Gains and Losses, is often used in conjunction with Form 4797. For further information, refer to Publication 544, Sales on Other Disposition of Assets,Publication 550, Investment Income and Expense, the Instructions to Form 4797 (PDF), Sale of Business Property, and the Instructions to Form 1040, Schedule D, Capital Gain and Losses.

We are selling rental property and have never claimed depreciation. What do we do about this when we file our taxes?

When reporting the sale of or computing gain or loss on rental property, you are required to make an adjustment to your basis for allowable depreciation regardless of whether the deduction was taken. For more information refer to Publication 544, Sales or Other Dispositions of Assets, and the Instructions for Form 4797, Sales of Business Property.

You can claim the depreciation not taken for the rental property in the years before the year of sale. How to do this depends on when you placed in service the rental property. If you placed in service the rental property before calendar year 2003, you may amend your income tax returns for the years before the year of the sale by using Form 1040X (PDF), Amended U.S. Individual Income Tax Return, to take the depreciation deductions for the rental property that should have been taken. Or, you may file a Form 3115 (PDF), Application for Change in Accounting Method, to claim the depreciation for the rental property that should have been taken for the years before the year of the sale. The Form 3115 must be timely filed for the same tax year in which you sell the rental property.

If you placed in service the rental property after calendar year 2002 and you have unclaimed depreciation for two or more years before the year of sale, you must use Form 3115 (PDF), Application for Change in Accounting Method, to claim the depreciation for the rental property that should have been taken for the years before the year of the sale. The Form 3115 must be timely filed for the same tax year in which you sell the rental property.

If you placed in service the rental property after calendar year 2002 and you have unclaimed depreciation for only the year immediately preceding the year of sale, you may amend your income tax return for that prior year by using Form 1040X (PDF), Amended U.S. Individual Income Tax Return, to take the depreciation deduction for the rental property that should have been taken. Or, you may file a Form 3115 (PDF), Application for Change in Accounting Method, to claim the depreciation for the rental property that should have been taken for the prior year. The Form 3115 must be timely filed for the same tax year in which you sell the rental property.

What forms do we file to report a loss on the sale of a rental property?
