My girlfriend and I both take care of our child but I'm letting her claim it as dependent but it said we can only have it's ss# on one of our tax returns but I still need it for head of household hi what does this work
To prevent fraudulent returns, the IRS will only accept each dependent's SSN once in their e-file system. Since your girlfriend claimed your child as a dependent and e-filed, no further e-files using that SSN will be accepted. However, you can print, sign, and mail in your tax return using the child's SSN. Your tax return will be accepted if you paper-file.
