April 2026 Business Tax Deadlines for Entrepreneurs

April is a crucial month for compliance. Whether you run a Texas-based service agency or a nationwide consultancy, staying ahead of these April 2026 tax deadlines keeps your cash flow healthy and helps avoid unnecessary IRS penalties. At Freedom Line Accounting & Tax, we believe small business owners deserve clarity, so let's break down exactly what is due.

April 15 Deadlines

  • C-Corporations: File your 2025 income tax return (Form 1120) and pay any tax due. Need more time? File Form 7004 for an automatic 6-month extension and deposit your estimated tax. Extensions protect against late filing, not late payment penalties! You also need to pay your first installment of 2026 estimated taxes today.

  • Payroll & Withholding: Deposit Social Security, Medicare, and withheld income tax for March if the monthly deposit rule applies. The same rule applies for non-payroll withholding.

  • Fiduciary Returns: Timely file a 2025 calendar year fiduciary return (Form 1041) or request an extension.

April 30 Deadlines

  • Quarterly Payroll (Form 941): File for the first quarter of 2026 and pay any undeposited tax. If you deposited everything on time, you have until May 11 to file.

  • Federal Unemployment Tax (FUTA): Deposit the tax owed through March if it exceeds $500.

Weekend & Disaster Rules: Deadlines falling on weekends or legal holidays automatically push to the next business day. If your area faces a natural disaster, the IRS often grants relief. Check FEMA or the IRS disaster relief page to see if your deadlines are extended.
