If you need to file a late tax return this year, there is good news! Filing an extension will give you until October to complete and file your return. Please note, this does not give you an extension to pay, only to file. Not paying on time may result in late fees. Should you need extra time to pay, you can contact the IRS for a payment plan. If you are expecting a refund, there is no need to file an extension, you won't be penalized.
