You should receive your W-2 form from your employer by January 31 each year, as required by federal law. If the deadline falls on a weekend or holiday, it may be sent the next business day. Employers must mail or provide the W-2 form electronically by this date. If you haven't received your W-2 by early February, you should contact your employer. If it's still not received by the end of February, you can contact the IRS for assistance. The deadline is the same even if you have left the job earlier in the year, unless you request it sooner, in which case the employer has 30 days to provide it.
