If you’re not done with your taxes, don’t worry, just get an extension. Just send in IRS Form 4868 and you’ll get 6-months to send in your paperwork. However, you still need to send in 90% of your total tax due otherwise you’ll get fines. If you’re getting a refund, then no sweat, just send in your extension. Don’t feel too bad about not having it together in time, either; according to the IRS website, form 4868 is their most requested document.
