Thinking an Extension Means More Time To Pay

The biggest mistake people make when filing a tax extension is understanding what it means to file an extension.

Mark Steber, chief tax information officer at Jackson Hewitt, said that usually people think filing an extension means there's more time to file and pay. The reality is it's only more time to file. If taxpayers have a balance due on Tax Day, they have to pay it.

Not Filing a State Extension

In addition to filing an extension on your federal tax return, you must also file your state return. Each state has different rules about filing a state tax extension. States may also have different tax deadlines than federal tax deadlines. Rob Cordasco, CPA and founder of Cordasco & Company, PC, recommends reviewing your state extension filing rules.

"Although most states accept the IRS extension, some do not conform and require you to separately file an extension with the state on their predetermined forms," Cordasco said.

Filing the Wrong Extension Form

Do you know the difference between the two major tax extension forms? Logan Allec, CPA and owner of Choice Tax Relief, said the two forms are Form 4868 (for individuals) and Form 7004 (for businesses).

If you're using tax software to file your extension, Allec said your software will automatically know which form to use. Individuals using paper filing must use Form 4868. Do not accidentally file using Form 7004.

"It may seem obvious that you should use the form that has the word individual in its title rather than the word business, but stranger things have happened with tax forms," Allec said.

Using Incorrect Personal Information

Did your name or address change since your last communication with the IRS? Armine Alajian, CPA and founder of Alajian Group, said that if any of your personal information has changed, the IRS may not be able to match your tax information to the extension application information. Submit Form 8822 to the IRS to declare any changes in personal information. Otherwise, your extension is likely to be rejected.
