Iowa residents affected by the Aug. 10 derecho storm now have until Dec. 15 to file various individual and business tax returns and make tax payments, the Internal Revenue Service announced Monday. The tax relief postpones various tax filing and payment deadlines that occurred starting on Aug. 10. As a result, affected individuals and businesses will have until Dec. 15, 2020, to file returns and pay any taxes that were originally due during this period. The IRS is offering this relief to any area designated by the Federal Emergency Management Agency as qualifying for individual assistance. Currently this includes Linn County, but taxpayers in localities added later to the disaster area will automatically receive the same filing and payment relief. The current list of eligible localities and details on other returns, payments and tax-related actions qualifying for the additional time.will be available on the disaster relief page on IRS.gov.
