The IRS extends more federal tax deadlines. The extension, detailed in Notice 2020-23, includes a variety of tax form filings and payment obligations due between April 1 and July 15. Extended are estimated tax payments due June 15 and the deadline to claim refunds from 2016. The extended deadlines cover individuals, estates, corporations and others. The notice also suspends associated interest, additions to tax, and penalties for late filing or late payments until July 15, 2020. Contact us for more information. Previously, the IRS postponed the due dates for certain federal income tax payments. The new guidance expands on the filing and payment relief.
