Reversed the day and year on my child

Did you e-file already?   If you did not e-file you can go to MY INFO and fix it.   If you e-filed it is likely to be rejected because the SSN will not match the IRS records.   If it rejects, fix it and re-file it.

Now I’m questioning if I have done it the last few years?   Wouldn’t it have been rejected if I did

Yes, if your child's Birth Date was incorrect in a prior year tax return, your Efile would have Rejected.

 

The info must match Social Security records.
