Form Overview

IRS Form W2GU - W-2GU

Form W‑2GU is the Guam Wage and Tax Statement that employers use to report wages paid to employees and the taxes withheld. File it for each employee who worked in Guam during the tax year.

It captures total wages, tips, other compensation, federal and Guam income tax withheld, and any other statutory deductions.

  • 2Incorrect Social Security numbers
  • 3Mismatched wage totals versus payroll records
  • 4Wrong Guam tax‑withholding amount
  • 5Missing or late employee copy

Plain English

Think of W‑2GU as the Guam version of the regular W‑2. It tells the employee and the Guam tax authority how much you paid and what you held back for taxes. You only need it if you paid wages to someone who earned income in Guam.
