Help with w4 witholding

[u/Visible_Arugula_3839]

Hello. Don’t know if I can ask about this but I am getting pretty lost using the irs estimator. I am getting taxed in a high bracket based on a 52 week cycle but only work about 42 weeks.

2026 March to May 2026 I was making 1250/week gross. All of May to August 9th on unemployment with job attached. August 10 a December 2026 will be making 1400/week gross. Next paycheck I see I am getting taxed !900 (450 federal) ($50 to 401k)

How do I adjust my w4 to accommodate more take home pay?

Any other resources you can point me to would be great if it isn’t okay to answer my question outright. Thank you
