The Internal Revenue Service has issued final rules on the 20 percent business income deduction (Sec. 199A of the Tax Code) that was enacted in late 2017 as part of the Tax Cuts and Jobs Act. Among other things, the rules confirm that the deduction applies to your business income, as a real estate agent or broker, if you operate as a sole proprietor or owner of a partnership, S corporation, or limited liability company. It applies even if your income exceeds a threshold set in the law of $157,500 for single filers and $315,000 for joint filers. In addition, the rules provide guidance that NAR has been seeking on two other provisions of importance to you: 1) whether any real estate rental income you have is eligible for the deduction, and 2) how the deduction applies to properties you've exchanged under Sec. 1031 of the tax code.
