2025 Tax Updates & Employee Actions

We want to help prepare you for a smooth tax-filing season ahead! Here’s what you need to know.

For all HII employees:

Make sure your name, address, and withholding information are correct, so your W-2 is accurate!

Your first and last name on your pay stub must exactly match what’s on your Social Security card.
Verify your home address using the instructions provided below.
Deadline for updates is January 9, 2026.

For overtime-eligible employees:

Some employees may qualify for a new overtime deduction for the 2025 tax year. Eligible employees may be able to deduct a portion of their qualified overtime earnings on their federal income tax return, potentially lowering their taxable income. Look for more information on this subject in January.

What overtime is deductible?

Only overtime pay required under the Fair Labor Standards Act (FLSA) is deductible.
Generally, FLSA requires overtime pay for hours worked over 40 hours in a workweek at a rate of no less than 1½ times the regular hourly rate.
If you receive overtime pay that is more than 1½ times your regular hourly rate, only the premium time required under FLSA is deductible. For example, if your regular hourly rate is $20 per hour, $30 is the required hourly rate for overtime hours. This means that $10 per hour of overtime may be deductible on your federal income tax return. In this example, any overtime premium pay in excess of $10 an hour would not be deductible on your tax return.
Overtime deduction is limited to $12,500 per return ($25,000 for joint return).

The Internal Revenue Service (IRS) recently published guidance for this deduction for the 2025 tax year:

The IRS did not update the W-2 forms to include overtime information.
Employers are not required to report overtime separately.
If you plan to claim this deduction, please keep your final pay stub. The IRS provides instructions on how to calculate the deduction at IRS overtime guidance.
Final 2025 pay stub dates will be:
- Ingalls: Dec. 18
- Corporate, Mission Technologies and NNS Salaried: Dec. 19
- NNS union-represented: Dec. 26

Reminder: Your final pay stub is not a replacement for your W-2. You’ll still need your W-2 to file your taxes.

For those expecting to claim exemption from federal income taxes:

If you had no federal income tax liability in 2025 and don’t expect to owe any federal income tax in 2026, you can claim exemption from federal tax withholding for 2026:

You must submit a new W-4 by Feb. 17, 2026, even if you were exempt in 2025.
If Payroll does not receive a new W-4 by the deadline, your withholding status will change to single with no dependents or deductions starting with the pay period ending Mar. 8, 2026.
For IRS rules on exempt status, visit: IRS exempt guidance.
