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.
For individual ChatGPT accounts, your billing email may differ from the email you use to sign in to ChatGPT. For help identifying your account, see: Troubleshooting ChatGPT sign-in. To change the email you use to sign in, see: Changing your email address.
Individual ChatGPT accounts
Go to chatgpt.com.
Select your profile icon, then select Settings.
Select the Billing tab.
Under Billing information, select Edit.
Update your billing information, including adding your Tax ID, as needed.
Select Save.
If billing or payment controls are missing, sign in to the same ChatGPT account in a different browser, then try opening your billing settings again. For example, if the controls don’t appear in Safari, try Chrome.
If you see Payment in Account settings
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.
Select Edit.
Update your billing information, including adding your Tax ID, as needed.
Select Save.
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.
If the Tax ID field is missing or your billing country changes back after you save it, check the billing profile for the purchase.
For a personal subscription bought on chatgpt.com, sign in to the account that paid. If its billing or payment controls are missing, sign in to the same account in a different browser and reopen your billing settings.
For ChatGPT Business, ask an owner to switch to the billed workspace and open its billing settings. For an API purchase, ask someone with permission to manage billing for the organization that paid to open its billing preferences.
If the Tax ID field is still missing or the saved country still changes back, contact Support with the product, billing country, field name and when you saw the problem. Hide payment details and your full Tax ID in screenshots.
Invoice changes
Updating your billing details or Tax ID only affects future invoices. It does not revise invoices that have already been issued.
To request a review of an existing invoice, contact OpenAI Support using the Help Center chat widget. Include:
The invoice number for each invoice you want reviewed.
What needs to change, including the details currently shown and the correction you are requesting.
The billing name, billing address, and Tax ID or VAT ID you want shown, as applicable to your request.
Support will review whether the invoice can be reissued. A reissue is not guaranteed. To use the corrected details on future invoices, also update your billing information using the steps above.
