Can you change from filing jointly to separately?

Taxpayers who file a joint return cant choose to file separate returns for that year after the due date of the return. A citizen or resident alien married to a nonresident alien may be able to choose from more than one filing status.

What is the penalty for filing an amended tax return?

There is no penalty for simply filing an amended return. But if your mistake caused you to underpay tax, you will owe that additional tax. If you amend your tax return before the April deadline and pay the remaining tax you owe, you wont have to pay a penalty.

Can multiple years of tax returns be mailed together?

Sure--one trip to the mailbox is fine. But do not combine different tax years in the same envelope. Each one needs it own envelope. Federal and state returns go to different addresses, too.

Is amending a tax return a red flag?

Amended returns will probably generate closer scrutiny by the IRS. Filing an amended return, particularly if it results in a significant decrease in tax, is almost guaranteed to get a second look by the IRS.

How far back can a corporation amend a tax return?

To claim a refund, you must file Form 1040-X within 3 years after the date you filed your original return or within 2 years after the date you paid the tax, whichever is later.

Can I amend my tax return to file separately?

Can you amend a return to file separately?

You can amend a return to change from Married Filing Separately to Married Filing Jointly but not from Married Filing Jointly to Married Filing Separately unless you do so prior to the original filing deadline without extensions.
