When you onboard with Gigapay, we ask for your Tax Identification Number (TIN). This guide explains what a TIN is, which one to provide, and the formats we accept in different countries.
What is a TIN?
A TIN is the number your country's tax authority uses to identify you or your business. We are legally required to collect and verify it before we can send your Payouts — it's how we make sure your income is reported correctly.
Which TIN should I provide?
It depends on your Entity Type:
Individual: your personal tax number — the one on your tax documents or national ID.
Sole Trader: your business TIN. It must be valid for cross-border transactions.
Company: your company's TIN and, where applicable, your VAT number. Both must be valid for cross-border transactions.
Country-specific formats
Here are the countries we get the most questions about. If yours isn't listed, your national tax authority's website will state the format of your TIN.
Country | Entity Type | What to provide |
Sweden | Individual | Personal identity number (personnummer). If you onboard with BankID, this is filled in for you. |
Netherlands | Individual | Your BSN (Burgerservicenummer). If you see a field labelled "Blik", enter your BSN there. |
Netherlands | Sole Trader | Your RSIN, issued by the Belastingdienst. The RSIN is mandatory and cannot be waived. |
Germany | Individual | Steuerliche Identifikationsnummer — 11 digits, numbers only, and it never starts with 0. |
Italy | Individual | Codice Fiscale. |
France | Sole Trader / Company | SIREN or SIRET. |
Australia | Sole Trader / Company | A valid Australian TIN together with your national Australian ID. |
What your TIN is called in your country
For Individuals, this is what your personal TIN is called locally. The list is non-exhaustive — if you have multiple TINs, use the one relevant for the country where your work is performed.

My TIN was rejected — what now?
Most rejections come down to one of these:
Formatting: enter the number without spaces, dashes, or country prefixes unless the field asks for them.
Wrong number type: make sure you're using your personal TIN as an Individual, and your business TIN as a Sole Trader or Company — they're usually different numbers.
Country mismatch: the TIN must be issued by the country you selected during onboarding.
If your TIN is valid and still being rejected, contact us — include your country, your Entity Type, and a screenshot of the error, and we'll look into it right away.
