What to enter in each W-2 box
Boxes a – f Employee and Employer identification info
Enter name, addresses, and other information to identify you and your nanny in Boxes a, b, c, e, and f. Leave Box d blank.
You can find your employee’s SSN and home address on Form I-9 that your nanny completed around first day of employment.
Box 1
The amount you need to enter into Box 1 is listed as Taxable wages on the Paycheck Nanny app.
This includes regular, overtime, bonus or other taxable pay for your nanny. If you are paying all of the FICA taxes on your nanny’s behalf, instead of withholding half of total Social Security and Medicare from their paycheck, the employee portion of FICA is also included in this amount.
This does not include SIMPLE IRA retirement plan contributions, Health Insurance benefits, or Commuter benefits for parking or mass transit costs.
Box 2
Enter in the amount of federal income tax withheld. If you did not withhold income tax from your employee’s paycheck, this will be 0.
Box 3
Social Security wages is often the the same as the Taxable Wages specified in Box 1.
One exception is if you as the employer also pay the employee’s portion of FICA for them. In this case, Box 1 value will be greater than Box 3. In this situation, include the extra employee portion of FICA paid by you in Box 1 but not Boxes 3 or 5.
Another exception is if participating in a SIMPLE IRA retirement plan, then your nanny’s contributions are included as Social Security and Medicare wages, but not taxable wages in box 1.
Box 4
Enter the amount of Social Security tax withheld from your employee’s paycheck.
Don’t worry about the employer portion when creating a W-2. That will come into play when you file form Schedule H with your own tax return.
Box 5
The Medicare wages will be the same as Box 3, as long as your nanny has earned less than $176,100 in 2025 from you, which is the cap on Social Security wage base but not Medicare.
Box 6
Enter the amount of Medicare tax withheld from your employee’s paycheck.
Don’t worry about the employer portion for creating a W-2. That will come into play when you file form Schedule H with your own tax return.
Box 12
If you employee has contributed to a SIMPLE IRA, specify the employee’s total contribution with code S. Note that any employer contribution to the SIMPLE IRA is not included on Form W-2.
If you have reimbursed Health Insurance costs for your nanny, enter the available amount in Box 12 with code FF, which is reserved for QSEHRA (Qualified Small Employer Health Reimbursement Arrangement) benefits. Note that the amount available should be entered here, even if the employee did not request reimbursement of the entire amount.
Box 13 Retirement Plan
Check the Retirement Plan box if your nanny has SIMPLE IRA or other retirement plan contributions.
Box 14 Other
Use Box 14 to provide record of additional employee paid taxes, such as Disability or Family Leave taxes for states that have those.
Employees who itemize deductions on their tax returns may be able to deduct these amounts from their income tax liability. If an employee chooses to take the standard deduction when filing their own personal income taxes, then they can ignore these values.
Notice that employer contributions to Family leave or disability plans, such as DC Paid Family Leave, are not included in Box 14.
California: Enter in the amount withheld from your employee’s paycheck to CA State Disability Insurance Tax as “CA SDI”.
Colorado: Report employee CO FAMLI premium deductions as “FAMLI”.
Connecticut: Specify CT Paid Leave employee contribution amount as “CTPL”.
Delaware: Indicate any employee contributions to Delaware Paid Leave (PFML).
Maine: Use the label “MEPFML” for Maine Paid Family Leave employee contribution amount.
Massachusetts: Indicate the employee paid portion of Family Medical Leave contributions with Description of “MAPFML”.
New Jersey: Follow NJ W-2 guidance to include worker contributions for UI, SDI, and Family Leave.
New York: Include employee contribution of SDI as “NY SDI”. Also indicate the Employee contribution of “NY Paid Family Leave”.
Oregon: Specify the amount of Paid Leave Oregon employee contribution.
Pennsylvania: Indicate Pennsylvania State Unemployment Insurance employee withholding as “PASUI”. Alternatively, “PA UC” can be used to abbreviate PA Unemployment Compensation. These indicate the same program.
Rhode Island: Include employee contribution of SDI as “RI SDI”.
Washington: While WA also has a Paid Family & Medical Leave program, it does not have a state income tax (for the employee to potentially deduct this amount from). So employee paid portions of this can be added as an FYI, but the WA Paid Family & Medical W2 Leave guidance does not specify it as required.
Box 15 Employer’s
Enter the abbreviation for the state of employment. For the ID, enter in your state issued Employer ID if your state has issued you one. Otherwise, re-enter your federal EIN.
Box 16 State wages, tips, etc.
If your state has a state income tax, enter in the taxable wages the state will consider. In most cases, this is the same amount as in Box 1.
Leave this blank if your state does not have an income tax.
Box 17
Enter in the amount of state income tax withheld. Leave this blank if you did not withhold any state income tax from your employee’s paycheck.
Box 18 Local wages, tips, etc.
If your locality has local income tax, in addition to the state income tax, enter in the taxable wages the state will consider. In most cases, this is the same amount as in Box 1.
Leave this blank if your city is not subject to additional local income tax.
Box 19 Local income tax
Enter in the amount of any local income tax withheld. Leave this blank if you did not withhold any state income tax from your employee’s paycheck.
