VAT and Tax ID
VAT number (if you are VAT-registered)
VAT status — Pre-filled. Confirm that it matches your tax status.
A VAT number is a unique identifier for businesses registered for VAT. It is used for VAT reporting and invoicing and is generally required for EU businesses providing services to businesses in other EU countries.
Tax ID (if you are not VAT-registered)
Your Tax ID is your tax identification number issued by your local tax authority. It is required if you are not eligible for a VAT number but still need to identify your business for tax purposes.
SIREN/SIRET (if VAT-exempt)
If your business is based in France and is exempt from VAT, enter your SIREN/SIRET.
Not sure which one applies to you?
You are VAT-registered → Enter your VAT number.
You are not VAT-registered → Enter your Tax ID.
You are based in France and VAT-exempt → Enter your SIREN/SIRET.
⚠️ You must provide the identifier that applies to your tax status. Without it, you won't be able to validate your invoice.
Europe — Don't have a VAT number?
If you're not eligible for a VAT number, you must register for a Tax ID with your local tax authority before you can continue working with Ocus.

Changing your legal name
This triggers a new identity verification. Your account may be temporarily under review, and payments may be delayed until verification is complete. Make sure all documents are valid and consistent.
When changes take effect
Billing updates apply to future invoices only — not past or ongoing billing cycles. Need to correct an already issued invoice → contact Ocus Support immediately via the chat bubble.
