Form W-3, the Transmittal of Wage and Tax Statements, is used to summarize the information from an employer ' s Forms W-2 and transmit them to the Social Security Administration (SSA). Since the implementation of the PATH Act, the deadline for filing both paper and electronic Forms W-2 and W-3 is January 31st of the year following the calendar year being reported. If January 31st falls on a weekend or legal holiday, the deadline is the next business day. This deadline is critical as it allows the SSA and the IRS to perform early reconciliations to detect and prevent tax refund fraud. Payroll professionals must ensure that year-end totals are reconciled between the payroll register, quarterly 941s, and the final W-3 before this January 31st deadline to avoid penalties for late or incorrect filing.
