Status of Unemployment Compensation Exclusion Corrections: The IRS continues to review tax year 2020 returns and process corrections for taxpayers who paid taxes on unemployment compensation, to exclude the compensation from income if eligible. To date, the IRS has issued over 11.8 million refunds totaling $14.5 billion. The IRS is now concentrating on more complex returns. Some taxpayers will receive refunds, while others will have the overpayment applied to taxes due or other debts. The IRS will mail a letter to affected taxpayers to inform them of the corrections, generally within 30 days from when the corrections were completed. See the 2020 Unemployment Compensation Exclusion FAQs for more information, including details on filing an amended return.
