Important Information on Filing Extensions
If you aren’t quite ready to file your taxes on April 15, you can file an extension. It’s very important to keep in mind that an extension buys you more time to file your paperwork (October 15), not more time to pay. If you owe money on taxes, the IRS will fine you 0.5% a month on your balance as of April 15.
However, this half-a-percent fee is much better than a failure to file. If you file after April 15 without an extension, the IRS will fine you 5% per month for failure-to-file. If you aren’t sure if you’ll make the April 15 filing deadline, an extension is always a good idea. And we can help you so the process stays seamless and stress-free.
