Postal Service™ employees are reminded that they are bound by the materials contained within the Code of Ethics, Principles of Ethical Conduct for Government Officers and Employees. This includes Principle 12, which states: “Employees shall satisfy in good faith their obligations as citizens, including all just financial obligations, especially those — such as federal, state, and local taxes — that are imposed by law.” It is vital that all Postal Service employees adhere to the highest possible ethical standards concerning the payment of their taxes and other debts.
As a Postal Service employee, you are personally responsible for ensuring correct federal, state, and local taxes are deducted from your pay. If you are subject to federal, state, or local taxes and the correct deductions are not being withheld from your pay, you must take immediate action to ensure appropriate tax withholdings. Adherence to these requirements will help employees avoid penalties and the potential of tax enforcement action by the IRS.
The IRS offers several online resources to help taxpayers bring taxes withheld closer to what is owed. The following resources are available anytime on irs.gov:
n A tax withholding estimator which helps determine the correct amount of federal tax to withhold at irs.gov/individuals/tax-withholding-estimator.
n Complete information on withholding, estimated taxes, FAQs, and more: irs.gov/individuals/employees/tax-withholding.
n Complete the federal Form W-4, Withholding Allowance Certificate, or the state equivalent of the federal Form W-4. (For example, to update Minnesota tax withholdings, complete Form W-4MN, Minnesota Withholding Allowance/Exemption Certificate). Complete the federal Form W-4, if your state does not have its own state equivalent to the federal Form W-4.
n Go to the LiteBlue home page (liteblue.usps.gov) to access the PostalEASE App.
n Update your Federal W-4 Payroll Module or your State Tax Payroll Module.
n If you do not have access to a computer or the Internet, you can call PostalEASE toll-free at 877-477-3273, option 1 and follow the instructions.
Note: It is to your advantage to complete the paper form prior to your PostalEASE update, as the paper form comes with helpful instructions for complex state withholding selections.
n Complete PS Form 4, Employee’s City or County Withholding Certificate.
n Forward your completed PS Form 4 to the HR Shared Service Center, PO Box 970400, Greensboro, NC 27497-0400.
n For additional information on local tax refer to Postal Bulletin # 22645 dated March 07, 2024.
Direct all questions concerning these taxes to the HRSSC at 877-477-3273, option 5 (TDD/TTY 800-877-8339).
The Postal Service does not provide tax advice to employees. Any questions regarding your tax liability or responsibility must be directed to the IRS or a qualified tax preparer.
