<prompt> Human: Last summer a former employer called and asked if I could work at a special event at their restaurant. The year before they screwed up my taxes and I had to pay 400 instead of getting a 200 refund, so I verified with them that this would be handled properly. I worked for 4 hours and received a check for 38.20, plus about 10 in tips. This was the only time I worked for them in the year 2016. I just got my W-2 and they reported my income as 512 and my tips as 90. What recourse do I have?  <response>: Contact your former employer and request a corrected Form W-2.If you do not receive the complete and correct W-2 by February 15 from the employer, call IRS at 1-800-829-1040 M - F 7am - 7pm local time for assistance. When you call, please have the following information available: your name, address, phone number, and social security number. You will also need to provide your employer name, address including ZIP code, and phone number, employer identification number if known.The IRS will contact the employer for you and request the corrected Form W-2. The IRS will also send you a Form 4852 Substitute for Form W-2, Wage and Tax Statement, along with a letter containing instructions.If you do not receive the corrected Form W-2 in sufficient time to file your tax return timely, you may use the Form 4852 to complete your return. If you receive the corrected Form W-2 after you file your return and a correction is needed, use Form 1040X to amend your original return.
