Maintain Updated Withholding Information in PostalEASE


As employees of the United States Postal Service®, we have a legal, moral, and fiduciary obligation to obey the tax laws of our country. As both citizens and public servants who are obligated to uphold the public trust, we are ethically mandated to complete and file all required tax forms for our federal, state, and where applicable, local taxes. We are required by appropriate taxation laws to pay our required taxes in a timely and accurate manner.

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.”

Postal Service employees must adhere to the highest possible ethical standards concerning the payment of their taxes and other debts. 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.

The Internal Revenue Service (IRS) offers several online resources to help taxpayers bring taxes withheld closer to what is owed. These resources are available anytime on They include:
