Learn about wages, salaries, and tips for your tax

Learn how to report wages, salaries, and tips on your Form W-2. Find explanations for every box on Form W-2 here.

As an employee, your employer must give you a Form W-2 by January 31. The W-2 reports:

  • Your wages
  • Contributions
  • Social Security
  • U.S. or Massachusetts retirement and Medicare tax
  • Withholding for state and federal income taxes.

If you didn't receive a W-2 from your employer, you should first contact them to verify whether it was mailed to the correct address. You can also call the IRS at (800) 829-1040 after February 15 to request a Substitute for Form W-2, Wage and Tax Statement (U.S. Form 4852). You should only request this form after reasonably attempting all you can to get a W-2 from your employer. We'll still accept a U.S. Form 4852 if you don't have a W-2, but you must still submit the year-end pay stub to verify the amount you filled in the "State tax withheld" box.

Allocated tips are in Box 8 and you must add them to state wages to determine total Massachusetts wages. If wage amounts include tips, you should contact your employers to be sure that allocated tips are reported correctly on the W-2.

Medicare tax paid is in Box 6 and you should add them to amounts paid for Social Security (Box 4) and/or U.S. or Massachusetts retirement as a deduction.

State income tax withheld in Box 17 is the amount that employers have withheld from wages.

Form 4852

On Form 4852, provide the following information to the IRS:

  • Your name, address, zip code, Social Security number
  • Your employer's or payer's name, address and zip code, and identification number (if known)
  • Estimation of wages, compensation, and taxes withheld

BOX 13:
If the "Statutory employee" box is checked, you are subject to Social Security and Medicare taxes but not federal or state income tax withholding.
If the "Retirement plan" box is checked, you were an active participant in any of the following:

  • Qualified pension, profit sharing or stock bonus plan
  • Annuity plan in 403(a)
  • Annuity contract or custodial account in 403(b)
  • SEP in 408(k)
  • SIMPLE in 408(p)
  • Trust in 501(c)(18)
  • Government plans, other than 457 plans. For state employees, this box indicates that you're a contributing member of the Commonwealth of Massachusetts Retirement System.

The "Third party sick pay" box is checked only if the employer is a third party sick pay payer filing Form W-2 for an insurer's employee.

BOX 14: Other - This box displays:

  • Post-tax retirement contribution - Any post-tax retirement contribution, which is federally taxed before being credited to your retirement account and has been taxed accordingly. The post-tax method is applicable for voluntary buy back (make-up) retirement contributions.
  • Pre-tax retirement - Retirement that was deducted from your earnings on a pre-tax basis. This retirement contribution will be federally taxed at a later date and thus will be taxed before being credited to your account. This will include all contributions to state retirement plans, higher education optional retirement plans, and any additional retirement paid during the calendar year, including make-up retirement deductions.
  • Health insurance premium - Your total payment of health insurance premiums paid on a pre-tax basis. These payments haven't been deducted on a tax-deferred basis and therefore contributions will not be taxed in later years.

BOX 15: State employer's stated I.D. number

BOX 16: State wages, tips, etc. - State taxable income, also known as stage wages. This is equal to your total gross pay during the calendar year minus:

  • Dependent Care Assistance Plan contributions (Box 10)
  • Tax Sheltered Annuity (Box 13)
  • Deferred Compensation contributions (Box 13), and
  • Health insurance premiums (Box 14)

This should also exclude:

  • Voluntary employee contributions to 403b retirement plans
  • Contributions to Savings Incentive Match Plan for Employees (SIMPLE) accounts
  • Qualified moving expenses reimbursement related to Massachusetts employment
  • Employer-provided educational assistance
  • Employer contributions to a medical savings account

This amount could be different from federal wages in Box 1 since Massachusetts doesn't exclude certain retirement plans from wages. This difference is due to pension contributions, which are excluded from income for federal tax purposes. When filing your Massachusetts income tax return, use the amount shown for state wages. If you enter the lower dollar amounts, your refunds will be delayed for correction. For Massachusetts wages, use the amount shown in Box 16.

BOX 17: State income tax withheld - State income taxes that employers withheld from your wages.

BOX 18: Local wages, tips, etc. - Income from which local or city tax was withheld.

BOX 19: Local income tax - Local or city taxes withheld.

BOX 20: Locality name - For states that have local taxes, this is the name of the local or city (such as New York City). Contact your department payroll office for:

  • A form W-2c (Statement of Corrected Income and Tax Amounts) if your name, social security number, or any of the information reported on your Form W-2 is incorrect
  • A reprint of your Form W-2 if necessary
  • Any other questions on specific Form W-2 items
