(WENY) -- Today is Tax Day and it is the last day to file a return or request an extension, unless you want to wind up paying a fee. People have until the end of the day to mail off their correct paperwork, or file online.  

“If you’re going to do it by mail, you want to make sure the postmark is for today,” John Fuld, an Internal Revenue Service spokesperson, said. “That means you would need to have all your paperwork filled out with the correct address, stamp-age, and what you need to do is...put it in the blue mailbox right there at the post office. 

Fuld said taking it to a post office is the safest way to mail your tax returned to make sure the mail is properly postmarked by April 15th. He added, be sure to send off your tax returns to the correct address. 

There are typically two different addresses to look out for. Your New York State Resident Income Tax Return’s address and your federal Individual Income Tax Return address need to be correctly filled out on the envelope. 

“You can go to https://www.irs.gov/ and get the address that you’re sanctioned with in your area because it does go to different addresses across the country,” he said. “Your state address...check your state and local tax bureau to find out where you actually need to mail your state taxes to.”  

For those who want to file before tonight’s deadline of midnight, online, there are a few options.  

“Direct File...which is the pilot program going on in the state of New York, right now,” he said. “You can go to https://www.irs.gov/ and click on ‘Direct File’ and see if you qualify for that.” 

If you do not qualify for Direct File, you can also use Free File if your gross income was $79,000 or less. You can use E-File and online paid services such as H&R Block and Turbo Tax. 

Fuld said it is important to keep in mind that the deadline to file for an extension is also today.  

“Tax Day is not an extension to pay,” he said. “If you do file an extension, which you can file an extension and that will be good until Oct. 15th, but...it’s not an extension to pay,” he said. “If you owe taxes, you do have to pay them by today. 

If you cannot pay the full amount of what is owed to the IRS, Fuld said he recommends you pay as much as you can now because you do not want to accrue filing fees.
