IRS Tax Tip 2021-26, March 1, 2021 Taxpayers should double-check to make sure they have all their documents before filing a tax return. Taxpayers who haven't received a W-2 or Form 1099 should contact the employer, payer or issuing agency and request the missing documents. This also applies for those who received an incorrect W-2 or Form 1099. If they can't get the forms, they must still file their tax return on time. To avoid filing an incomplete or amended return, they may need to use Form 4852, Substitute for Form W-2, Wage and Tax Statement or Form 1099-R, Distributions From Pensions, Annuities, Retirement or Profit-Sharing Plans, IRAs, Insurance Contracts, Etc. If a taxpayer doesn't receive the missing or corrected form in time to file their tax return, they can estimate the wages or payments made to them, as well as any taxes withheld. Then use Form 4852 to report this information on their federal tax return. If they receive the missing or corrected Form W-2 or Form 1099-R after filing their return and the information differs from their previous estimate, they must file Form 1040-X, Amended U.S. Individual Income Tax Return.

For some, this may have been the first time they ever received unemployment. These taxpayers need to know that unemployment compensation is taxable and must be included on their tax return.
