Hi!
I know you said you are aware of the W-4 Calculator tools; however, that's what I'm going to recommend. The calculator will let you feed in your EV credit (congratulations), bonuses, etc. and give you a good estimate. Then, throughout the year, keep your eye on changes in your tax situation (income, for example) and ytd withholding and be ready to make adjustments as needed. While you're doing this, don't forget your State taxes.
Good for you taking the time to work through the variable that will impact your tax liability and refund/balance due amount on your 2023 tax return.
