What is Withholding?

Amounts deducted from wages or payments by a payer and sent to the IRS as prepayment toward the recipient's tax liability.

Definition

Tax withholding is the amount of federal income tax that is deducted from an employee's wages by their employer and sent directly to the IRS. Withholding also applies to other payments such as pensions, bonuses, commissions, and gambling winnings. The amount withheld is based on the employee's Form W-4 elections. For international situations, withholding applies to payments to nonresident aliens under Chapter 3 (generally 30% unless reduced by treaty) and FATCA withholding under Chapter 4.

Who Needs to Know This?

All employees, pension recipients, and anyone receiving payments subject to withholding. International taxpayers need to understand treaty-reduced withholding rates.

Key Deadline

Withheld at time of payment; annual reconciliation on tax return

Potential Penalties

Employees may owe additional tax if under-withheld; employers face penalties for failure to withhold
