Changes to W4s

[WendyFoy]

I need to update my W4s because we have had to pay thousands in taxes each year.  I don't understand how to fill out the new W4 forms since the forms have changed.  We file Married with two or more incomes and have (1) 13 yr old dependent.  I looked over my last few years of taxes and it looks like we normally owe about $7200 in Federal and $2500 in (CA) State taxes each year but our withholdings are lower than that causing us to have to pay thousands each year.  Both my husband and I work full time, and my husband also has another part time job.  

How do we each complete the new W4 forms (for both federal and CA state) at each of our three jobs to make sure we have enough deductions taken out each year.

I've tried to use the IRS W4 calculation tool, but it just ends up with a zero.  So I don't think I'm completing it correctly.

TurboTax has an amazing TaxCaster that will generate a new W-4 when you simply enter the numbers and answer questions:  TurboTax W-4 calculator 

Keep in mind that although it says 2024 it does get updated.

Here is a link to help with California withholdings:  California earnings withholding calculator 



I would love to know if the TaxCaster works out for you.
