How do I update my address after my assignment ends?

Last updated: November 4, 2026

Applies to: Current and former US W-2 employees and independent contractors, and Canadian T4 employees. If you are employed outside the US and Canada, your in-country HR contact keeps your address, so ask them instead.

Summary: You can still log in after an assignment ends, so sign in at app.ascen.com and update your home address in your Profile. If you cannot log in, email support@ascen.com with your new address and we will update it for you. Do it before the end of the year: in the US, unless you have chosen electronic delivery, a paper copy of your W-2 or 1099 is mailed to the address on file.

If you can log in

  1. Log in at app.ascen.com. If you have forgotten your password, use Forgot Password? on the sign-in page. See How to log in, reset your password, and set up two-factor authentication.

  2. Open your Profile and update your home address.

  3. Save. The change takes effect right away.

Your home address has to be the physical street address where you live. A PO Box will not save. See Can I use a PO Box as my home address?.

If you cannot log in

Email support@ascen.com, from the email address on your Ascen account if you still can, with:

  • your full name;

  • your new home address, including any apartment or unit number, city, state or province, and ZIP or postal code;

  • that your assignment has ended, if it has.

We update your address and confirm by email. We may ask you to confirm a detail from your profile first. If the email address on your account is one you can no longer use, see I can't sign in because the email on my account is wrong or was changed.

If you got an email asking you to review your address

An email with a subject like "Action required: Add/Review your address to avoid year-end tax filing issues" is asking you to make sure the address on your record is complete and current before year-end tax forms are prepared. You do not need to use the link in the email: log in directly at app.ascen.com and follow the steps above. If you cannot log in, email support@ascen.com instead.

Why your address matters for your tax form

Your year-end tax form is posted to the Documents page of your account. In the US, if you have not chosen electronic delivery, a paper copy of your W-2 (employees) or 1099-NEC (independent contractors) is also mailed to the address on file.

If your address is out of date, the paper copy goes to your old address. You can still download the form from your Documents page. If you need a paper copy sent to your new address, update your address and email support@ascen.com to ask for it to be reissued.

Choosing electronic delivery means your form is available in your account as soon as it is ready, wherever you live. You can switch from Consent Settings in your account menu. See How to choose electronic or paper delivery for your W-2.

If you still have Ascen health coverage

Your health plan keeps its own copy of your address. After you change your address, email support@ascen.com and tell us, so we can update it with the plan.
