Employee taxes
Withheld from employee pay: federal income tax, employee Social Security and Medicare, and applicable state, local or employee programs.

Employee withholding and employer taxes are different amounts. Start with the wage bases you know, keep missing facts visible, and take location questions to the right official source.
01
Withheld from employee pay: federal income tax, employee Social Security and Medicare, and applicable state, local or employee programs.
02
The employer’s own cost. Employer FICA, FUTA, state unemployment and other applicable employer programs do not become employee deductions here.
03
Use a separate wage base for each tax. Benefit and retirement deductions do not all have the same treatment. This page does not decide taxability from a label.

Select the states to build a review checklist. Enter exact street addresses directly at the official agency’s address tool when available. This page asks for no street address and does not perform an address-tax lookup.
A ZIP code, postal city, Census location or map pin is not a tax-jurisdiction determination. Review effective dates, local boundaries, resident/nonresident rules, certificates and employer facts. Working remotely does not by itself settle which state may require withholding.

Amounts stay in this page’s memory. They are not saved to your account, sent to a tax provider, or placed in analytics by this tool. Do not enter a name, address, SSN, account number or employee file.
A current free profile is enough. Newsletter and promotional email are separate, optional choices.
