Important Reminders

  • Extensions Available: You can file for a 6-month extension for individual returns, but taxes owed are still due by April 15 to avoid penalties.
  • Quarterly Estimated Taxes: Self-employed individuals and businesses must pay estimated taxes quarterly to avoid underpayment penalties.
  • Weekend/Holiday Adjustments: If a deadline falls on a weekend or federal holiday, the deadline is moved to the next business day.
  • State Deadlines: State tax deadlines may differ from federal deadlines. Check with your state tax authority for specific dates.
  • Penalties & Interest: Late filing and late payment penalties can be steep (5% per month for late filing, 0.5% per month for late payment). Always file on time!
  • Multiple Deadlines? Business owners often have multiple deadlines to track. Consider working with a CPA to ensure nothing is missed.
