Extension for Filing Individual Income Tax Return
Request an extension of time to file an Individual Income Tax Return (D-400)
- Does not provide an extension of time to pay the tax due
- Must file the extension by the original due date of your return
How long is the extension?
In most cases, the extension provides an additional six months to file your return. If you were already granted an additional four months to file because you were out of the country, the extension provides an additional two months to file your return.
Can I make a payment?
You can pay the tax due when you file an extension. If you don’t, this form will not provide an extension of time to pay the tax due. If you do not pay the full tax due by the original due date of the return, penalties and interest will be assessed.
Are my submissions secure?
