The IRS will provide taxpayers with additional guidance on those provisions that could affect their 2020 tax return, including the retroactive provision that makes the first $10,200 of 2020 unemployment benefits nontaxable. For those who haven't filed yet, the IRS will provide a worksheet for paper filers and work with software industry to update current tax software so that taxpayers can determine how to report their unemployment income on their 2020 tax return. For those who received unemployment benefits last year and have already filed their 2020 tax return, the IRS emphasizes they should not file an amended return at this time, until the IRS issues additional guidance.
