Overview
This article explains where to update billing information, including Tax ID and VAT ID, for ChatGPT and OpenAI API accounts. It also explains when billing changes apply to invoices.
If the Tax ID you provide is found to be invalid, it may be removed from system records at any time and applicable taxes may be charged.
Update billing information
How you update billing information depends on your account type.
Individual ChatGPT accounts

Open Settings, then select Account.
Under Payment, select Manage to open the billing portal.
Under Billing information, select Update information to edit your billing details.
ChatGPT Business accounts
Before you begin, sign in as an owner of the Business workspace whose billing information you want to update, and switch to that workspace.
Go to chatgpt.com.
Select your profile icon, then select Workspace settings.
Select Billing.
Select Settings.

OpenAI API accounts
If you have permission to manage billing for an API organization, go to your organization’s billing preferences to view and update its billing information, including adding your Tax ID.
Invoice changes
Changes to billing information or Tax ID apply to future invoices only. Previously issued invoices cannot be updated retroactively through these settings.
If you need a review or possible reissue of a previously issued invoice, contact OpenAI Support through the Help Center chat widget and include the relevant invoice number.
