FAQs

How does the W-4 calculator work?
It estimates your annual federal tax from your income and compares it with what you're on track to withhold, then suggests an adjustment for Form W-4.
Does it include state withholding?
No — federal only. Your tax pro can help with state.
Can I use it if I'm self-employed?
If you have both wages and self-employment income, enter the self-employment income as other income. If you're only self-employed, you make quarterly estimated payments instead.
