For at least 10 years, Katie Gunby has waited until the last week to file her taxes -- on purpose.
"It's just the joy and thrill of waiting until the last minute. If I have to pay, that means I've kept my money a little longer. I don't want to give it up freely or quickly," the Lincolnton resident said.
On Tuesday, the funeral home director was filing her taxes at H&R Block on Wrightsboro Road.
Even when she got her taxes done earlier, she always waited until the last week to mail in her check if she owed the Internal Revenue Service.
One year, she waited until the very last day to get her taxes done.
"It was like a madhouse. I promised not to wait until the last day anymore, but I still get it done the last week," she said.
Casey Fish, of Martinez, usually procrastinates when it comes to filing his taxes, but this is the latest he's ever waited, he said at H&R Block on Tuesday.
Usually, he files his taxes six or seven days before the deadline. He's been busy with work and hasn't had time to file this tax season. His return is simple and he expects to get a refund of about $800.
Other people such as Fish and Gunby are keeping tax offices busy this week.
"April 15 will be an extremely busy day for us, there's no doubt about that," said Steve Harvey, the district manager for H&R Block. "There are people who do wait intentionally. We've got people who have called us and made an appointment for April 15."
For the most part, Harvey attributes this last-minute rush to procrastination. However, many people still working on their taxes include business owners who are gathering information in order to file their return. Other taxpayers haven't filed because they have a balance due and aren't in a hurry to pay the IRS.
"We're trying to encourage them to get out of that habit because we can do the return and file it and set it up so they don't have to pay until April 15. It's still a hard lesson that people aren't picking up on too quickly yet," Harvey said.
Post offices expect the volume of mail to be heavier than a normal business day, but they won't be extending their business hours, said Tim Goodwin, the acting postmaster at the Augusta Main Post Office.
Taxpayers need to mail their returns during normal business hours, he said. Three branches are allowing taxpayers to place their returns in lobby drop boxes until midnight: downtown Augusta, Martinez and Evans.
In Georgia, the IRS has received 2.6 million electronic returns and expects to receive 3 million by the end of tax season. In South Carolina, 1.2 million returns have been filed electronically this year, said IRS spokesman Mark Green.
The method of filing -- by mail or electronically -- doesn't alter the deadline.
"You need to have your return in by midnight to be safe," he said.
Today -- also by midnight -- is the last day to file for an extension, Green said. The IRS estimates more than 300,000 Georgians will request one this year.
After today, taxpayers will have to pay penalty fees, including those for failure to file and failure to pay.
