Get your taxes done using TurboTax

What you enter on the W-4 that you give to your employer to withhold federal income taxes from your wages has no bearing whatsoever on the filing status you enter on your tax return.

If you are legally married as of 12/31/2024 then you can file as Married Filing Jointly on the 2024 tax return.

All income from all sources for the both of you will be entered on only one tax return when filing jointly.
