Should a primary residence (that was later a rental property) that was sold be entered as a "sale of business property"?

It depends but if you did not rent it during 2016 and are claiming the home gain exclusion, you will want to report it under the home sales section.

Yes, you will report this as the sale of your primary residence.

You can take the gain exclusion as long as you considered the home your "primary residence" for 2 of the last 5 years. If you have a capital gain from the sale of your main home, you may qualify to exclude up to $250,000 of that gain from your income. You may qualify to exclude up to $500,000 of that gain if you file a joint return with your spouse. See  Sale of Your Home for more information on the exclusion.

Although you may be able to claim the home gain exclusion on this sale, you will still have to paid a capital gain related to the depreciation taken on the home during the time it was a rental property.

When you sell a property that was used as a rental, you must pay 25 percent recapture tax (also referred to as Section 1250 recapture) as well as regular state income tax on the depreciation you claimed. (Remember the IRS will assume that you claimed the correct amount of depreciation every year—this is true regardless of whether you actually claimed any depreciation on your tax return).

In order to calculate the capital gain or loss when you sell a residence that had been converted to rental property, you need to know three things:

• Your adjusted tax basis in the property (both at the time of the conversion and the time of the sale)
• The sale price
• The fair market value of the property when it was converted to rental property

If the converted property is later sold at a gain, the basis for purposes of determining the capital gain is your adjusted tax basis in the property at the time of the sale. If the sale results in a loss, however, the basis used is the lower of the property's adjusted tax basis at the time of the conversion or the fair market value when the property was converted from personal use to rental property. This loss rule ensures that any deflation in value occurring while the property was held as a principal residence does not later become deductible upon your sale of the rental property; a loss on the sale of a principal residence is not deductible. As usual, you calculate your capital gain by subtracting your adjusted basis from the sale price of the property.

To enter the sale of your primary residence, please follow these steps:

1. Once you are in your tax return (for TurboTax Online sign-in, click Here), click on the “Federal Taxes” tab ("Personal" tab in TurboTax Home & Business)
2. Next click on “Wages & Income” ("Personal Income" in TurboTax Home & Business)
3. Next click on “I’ll choose what I work on”
4. Scroll down the screen until to come to the section “Less Common Income”
5. Choose “Sale of Home (gain or loss)” and select “start’
6. You will want to use the "Easy Guide" to determine the adjusted basis on this home 

Say "yes" that you sold your main home and TurboTax will guide you on entering this information.  You will need:

• The date you sold your home and the selling price (from your closing statement)
• The date you bought your home and the purchase price (from your closing statement)
• The cost of any major improvements you made, so we can deduct them for you
• Form 1099-C if you sold your home at a loss (short sale)

However if you did rent it during 2016;

• Under the rental section - if rented during 2016
• Under the sale of business property - if you used the FMV at time of conversion (instead of cost basis).

hello, i have same issue. Kinda. I sold my rental which i lived in for 2 years and rented out for 2 years so I qualified for the exclusion. I reported it as a sale of rental, last year’s taxes. About a year later, I sold my main home, will that be same exclusion? But I reported my rental as sale of business not sale if main home.
