I just got married in November and I didn't think anything of filing as single; however, my husband wants to file together. How do I withdraw my tax application that I submitted just two days ago?
Yes, if you need to file an amended tax return after IRS accepted your tax return due to a marital status change, then you will need to wait until your original tax return is processed by the IRS. If you are receiving a refund, you should wait until the check is issued. Amended returns must be filed by mail.
The article below will have the specific 2016 instructions in mid-February.
