Child Tax Credit Under Married Filing Separately & W-4 Form Adjustment

Hi everyone,

We are expecting a newborn in 2025 and plan to file our taxes under Married Filing Separately. To maximize the $2,000 Child Tax Credit, both my spouse and I submitted W-4 forms with $1,000 entered in Step 3 ("Add the amounts above for qualifying children and other dependents...") to reduce withholding from our employers.

However, I recently came across an article stating that Married Filing Separately may not allow an equal split of the $2,000 Child Tax Credit between spouses. Now, I’m unsure if our current approach is correct.

I have a few questions:

  1. Can we each claim $1,000 of the Child Tax Credit under Married Filing Separately, or is that not allowed?
  2. If splitting is not allowed, how should we correct our W-4 forms to avoid potential tax issues?
  3. If it is allowed but we need to take additional steps, what should we do?

I’d appreciate any guidance on how to properly handle this situation. Thanks in advance!W-4 Step 3.png
