What this category covers
This page groups IRS forms related to employment & payroll tax (940/941 series).
Quarterly and annual forms for employers to report wages, tips, and payroll taxes withheld from employee paychecks.
Employers use the 940/941 series to report wages paid to employees and fulfill payroll tax obligations. Form 941 is filed quarterly to report wages, tips, federal income tax withheld, and both employer and employee shares of Social Security and Medicare taxes. Form 940 is filed annually for Federal Unemployment Tax (FUTA). Form 944 allows certain small employers to file annually instead of quarterly. Railroad employers use the CT-1 series. These forms are critical for IRS compliance — late filing and late payment penalties accumulate quickly, and the IRS rigorously cross-references these filings with W-2s and individual tax returns.
