What Happens If You Miss a Deadline?

The IRS charges a Failure to File penalty of 5% of unpaid taxes per month (up to 25%), plus a Failure to Pay penalty of 0.5% per month. Interest compounds daily on any unpaid balance.

If you can't file on time, I can prepare an extension (Form 4868) to push your deadline to October 15th. An extension gives you more time to file, but not more time to pay.

Don't Wait Until the Last Minute

Get ahead of the deadlines. Call to schedule today.
