Frequently Asked Questions
1. Does my employer need a new W-4 for the OBBBA changes? Yes. While old forms still work for basic withholding, you must use the 2026 version of the form to claim the new tips, overtime, and car loan interest deductions in your paycheck.
2. What happens if I over-estimate my overtime? If you estimate $12,500 in overtime but only earn $5,000, you will under-withhold and may owe a small balance at year-end. It is best to be conservative with Step 4(b) estimates.
3. Is the SALT cap really $40,400 for withholding? Yes. If you live in a high-tax state and plan to itemize, putting your estimated SALT (up to $40,400) in Step 4(b) is the fastest way to get an immediate $200–$500 monthly boost to your net pay.
