The IRS has announced that it will waive the Section 6654 penalty for the underpayment of estimated income tax for certain individuals who would otherwise be required to make estimated payments on or before 1/15/19. The waiver is limited to individuals whose total withholding and estimated tax payments equal or exceed 85% of the tax shown on their 2018 returns. (The usual percentage threshold is 90%.) Taxpayers should complete Part I of Form 2210 (Underpayment of Estimated Tax by Individuals, Estates, and Trusts) to determine if the waiver applies. If it applies, taxpayers should check the waiver box (Part II, Box A) and include the statement “85% Waiver” with the return.
