Business licence renewal in Guam

How to renew a business licence — how it works anywhere

Written from published rules on 3 September 2026. Not monitored for changes since. A starting point, not official advice — confirm anything that matters with Department of Revenue and Taxation (DRT).

Renewing a business license in Guam involves submitting an annual renewal application to the Department of Revenue and Taxation. The process ensures that all business registration details remain current and that mandatory tax filings are up to date.

Your timing

It is generally recommended to begin the renewal process at least 30 days before the license expiration date. This allows sufficient time to resolve potential administrative delays, such as outstanding tax liabilities or the need for updated clearances from other government agencies.

Start 30 days ahead

Processing times can fluctuate based on the volume of applications and the time required to verify tax compliance status.

The process

  1. 1Ensure all required annual income tax and gross receipts tax filings are up to date with the Department of Revenue and Taxation.
  2. 2Obtain any necessary clearances or health permits if the business industry requires specific regulatory approval.
  3. 3Complete the official business license renewal application form provided by the DRT.
  4. 4Submit the completed application along with the required payment to the DRT Licensing and Registration Branch.
  5. 5Receive the updated license document, which should be displayed at the place of business.

What to bring

  • Completed business license renewal application form
  • Current business license for reference
  • Proof of tax compliance or clearance documents
  • Payment for the applicable renewal fees

Fees vary based on the classification and structure of the business; applicants should confirm the specific fee schedule directly through the Department of Revenue and Taxation website or office.

What commonly goes wrong

  • Failure to maintain current tax filings can result in the rejection of a renewal application.
  • If the business location or legal structure has changed, a new registration or amendment may be required instead of a standard renewal.
  • Operating with an expired license can lead to penalties or the temporary suspension of business activities.
