Form 941 and Form 1040-ES: quarterly tax filing explained

Executive overview

Two federal tax forms must be filed four times a year: Form 941 (employer's quarterly federal tax return) and Form 1040-ES (estimated tax for the self-employed). Employers use 941 to report withheld taxes; self-employed individuals use 1040-ES to pre-pay tax on income not subject to withholding.

Missing deadlines or underpaying triggers IRS penalties.

Who must file each form

  • Form 941: any business that pays employees
  • Form 1040-ES: sole proprietors, independent contractors, LLC members, anyone with untaxed income
  • Employees whose employers withhold taxes do not file 1040-ES
  • Income types requiring estimated tax: self-employment, freelance, dividends, capital gains, interest, alimony, prizes
