944 is a reference to IRS Form 944, which is an annual tax return that certain small business owners can file instead of the quarterly Form 941. Form 944 is designed to report the taxes, including federal income tax, social security tax, and Medicare tax, that employers have withheld from their employees paychecks. Small employers whose annual liability for Medicare, Social Security, and federal income taxes withheld from employees is $1,000 or less can file Form 944 and only pay federal employment taxes once per year, not quarterly. The form allows employers to report employee wages, tips, and other information. Form 944 must be filed by January 31 of the current year for the previous year that is being reported.
