Late on filing your tax return and thinking about filing an extension?

Here is what filing an extension actually means.

Filing an extension is not the end of the world. In fact, many business owners and real estate investors file extensions every year. I have done it myself. It is common when you need additional time to make sure everything is accurate and complete.

An extension gives you an additional 6 months to file your federal and state tax returns.
It does not give you more time to pay.

What an Extension Actually Does

  • Gives you until September 15th or October 15th to file depending on your entity type
  • Helps you avoid late filing penalties
  • Allows time to finalize bookkeeping, documents, and strategy

Pros of Filing an Extension

  • More time to clean up your financials
    • Example: A business owner behind on bookkeeping can finalize everything properly instead of rushing and filing an inaccurate return
  • Helps you avoid failure to file penalties
    • These can be significant, especially for partnerships and S-Corps at $245 per owner per month
  • Can help with lending situations
    • Example: If your 2024 income was strong but 2025 dipped, lenders may rely on your 2024 return while 2025 is on extension
  • More time for certain tax strategies
    • Example: SEP IRA and Solo 401k contributions can still be made after April, potentially creating a $23,500 to $70,000 deduction
  • Flexibility during a busy season
    • Many business owners are focused on operations in Q1 and need additional time to gather everything properly

Cons of Filing an Extension

  • Taxes are still due by the original deadline
  • March 15th for S-Corps and partnerships
  • April 15th for individuals
  • Interest and penalties can still apply
    • Example: If you owe $10,000 and do not pay by April 15, the IRS starts charging interest immediately
  • Easy to procrastinate
    • Many taxpayers extend and still end up rushing again in September or October
  • Delays clarity on your financial position
    • Example: Without a filed return, it can be harder to plan for loans, investments, or major decisions

How to Use an Extension the Right Way

An extension can be a powerful tool when used correctly.

The key is knowing your numbers. A smart approach is to estimate your tax liability and make a payment by the original deadline. That way, even if you file later, you avoid interest and penalties.

Another approach is proactive tax planning. When your books are clean and your strategy is in place, you should already have a solid estimate of your tax bill before the year ends. That puts you in control whether you file on time or extend.
