It depends.
It's based on more factors than simply income -- you need to take into account projected filing status, any other credits you might be entitled to, any deductions you might have, any additional non-salary income.
And, it's not always best to add dependents -- you can simply request extra withholding each pay period.
There are a couple of very good calculators you can use to estimate your needed withholding. You'll simply need to know what your filing status will be, the number of dependents you'll claim, your expected income, and deductions, and a few other factors.
TurboTax has a W-4 Calculator that will help you calculate your withholding for tax year 2023.
The IRS, also, has a very useful Tax Withholding Estimator.
And, finally, you can use the TurboTax program, itself. See the TurboTax Help article How do I update my 2023 withholdings and print a new W-4? for more information.
You might also see the IRS’ Credits for New Clean Vehicles Purchased in 2023 or After, to make sure you’ll qualify for the credit.
