1031 exchange basics for real estate investors

A 1031 exchange lets an investor sell real property held for investment or business use and reinvest in other like-kind real property while deferring the tax on the gain. It is one of the most useful tools in investment real estate, and one of the easiest to get wrong on timing.

Who commonly uses one

Investors trading up from a single rental to multifamily, owners moving from active management into lower-maintenance property, and business owners repositioning commercial real estate. A primary residence does not qualify, and neither does property held primarily for resale, such as a fix-and-flip. U.S. real estate is not like-kind to real estate outside the United States.

The two deadlines

• Identification: replacement property must be identified in writing within 45 days of selling the original property.
• Completion: the purchase must close within 180 days of the sale, or by the due date of that year’s tax return (including extensions), whichever is earlier.

These periods run at the same time, count calendar days, and are not extended for weekends or a hard market. The IRS grants extensions only in limited situations, such as certain federally declared disasters. The planning has to start before you list.

The qualified intermediary

The sale proceeds are usually held by a qualified intermediary rather than the seller. If the seller takes control of the funds, the exchange can fail. The intermediary should be engaged before the sale closes.

Common mistakes

• Listing the original property before looking at replacement options.
• Identifying only one replacement property with no backup.
• Taking cash or reducing debt without understanding the tax effect.
• Treating the exchange as a tax task instead of a coordinated real estate plan.

Questions to ask your CPA, tax counsel, and QI

1. Does my property and holding purpose qualify?
2. What happens if I receive cash or take on less debt?
3. Which identification rules fit my situation?
4. How will the exchange affect depreciation?
