State tax filing

@Mike9241 

I asked my employer and they asked me to fill out a NJ-W4 form. However, I was concerned that if I fill out this form, will I basically be paying double state taxes while waiting for a refund next year?

 

I only owed $600 to NJ state for 2023, but I wasn't sure if I can "manually" set the taxes withheld for NJ to match my actual tax liability vs just having another $800 deducted from my paycheck semiweekly. Any advice for my case?
