June 16, 2025: Monthly Payroll Tax Deposit Due – Employers

For employers following the monthly deposit schedule, June 16, 2025, is the deadline to remit your federal payroll tax deposits for wages paid in May. This includes:

  • Federal income tax withheld from employee paychecks
  • Employer and employee portions of Social Security and Medicare taxes (FICA)
  • Any nonpayroll withholdings (such as backup withholding from Form 1099 payments) if subject to the monthly schedule

Ensure your deposits are made via the IRS Electronic Federal Tax Payment System (EFTPS) to remain compliant and avoid late deposit penalties. Always review your payroll and withholding records thoroughly to ensure the correct amounts are deposited.

June 16, 2025: Second Estimated Tax Payment Due – Corporations

Corporations operating on a calendar year must submit their second estimated tax payment for the 2025 tax year by June 16. Estimated tax payments are a crucial component of corporate cash flow management, helping corporations avoid underpayment penalties and interest charges. Calculate your estimated payments carefully, using current year income projections, prior year figures, and adjusting for any midyear regulatory changes.

If your business has substantial non-corporate income (such as from partnerships or sole proprietorships), review your estimated tax obligations accordingly. Consult with your accountant if you anticipate major fluctuations in income or deductible expenses for the year.

Key Compliance Considerations

  • Weekends & Legal Holidays: If a federal tax due date falls on a Saturday, Sunday, or legal holiday, it is automatically extended to the next business day.
  • Disaster Area Filing Extensions: If your area is designated as a federal disaster zone, the IRS and FEMA may grant automatic filing extensions and penalty relief. Check the following resources for updates and eligibility:
