Return Information Notice - Code OX

You filed multiple returns for the tax year. We combined the returns and recomputed your tax, resulting in a reduced refund. In the future, report all your income on one return or use Form 540X to correct a return.

Why did I receive this notice code?

All income earned throughout the tax year must be combined. If additional income needs to be reported after you filed a return, file an amended tax return (Form 540X).

What do I need to do?

If you agree with our revisions, you do not need to contact us. Please update your records. If you have a revised balance due, please pay the amount due.

If you do not agree with our revisions, please contact us.
