Estimated tax payments for the second quarter of 2025 are due on Monday, June 16, with taxpayers who fail to pay on time facing underpayment penalties, the Internal Revenue Service (IRS) said in a June 6 statement.
Taxes have to be paid throughout the year on a pay-as-you-go schedule. One way to do this is by withholding taxes from wages, pensions, or government benefits such as social security. The second way is to make estimated tax payments on a quarterly basis.
