Tax ID / Business Number — What to Enter by Country

When you set up your profile, we ask for a tax identification number. This article explains what that number is for, why it doesn't work the same way everywhere, and exactly which number to enter depending on where you're based.

Why do we ask for this?

Two reasons:

1. Invoicing — your tax ID appears on the invoices we generate, so they're valid and usable for your own accounting and tax filing.
2. Commission calculation (EU chefs only) — if you're based in the EU, a valid, verified VAT number can lower your commission rate through the VAT reverse-charge mechanism (see our Commission & VAT article for details).

Important: this only affects commission for EU chefs

If you're based outside the EU (except the UK), your commission is a fixed 18.15%, whether or not you add a tax ID. This is because the VAT reverse-charge mechanism is an EU-specific rule and simply doesn't apply outside the EU.
So for non-EU chefs, adding your tax ID doesn't change your commission — it's purely so your invoices are correctly issued with the right identifier for your country. It's still worth adding, since it makes sure your invoices are usable for your own tax records, but don't expect it to lower your rate.
For UK chefs, commission is always 0%, regardless of VAT status — so this is also just for invoicing purposes.

What to enter, by country

Australia — Enter your ABN (Australian Business Number, 11 digits). This is issued by the ATO and applies to every business type, including sole traders. It's different from an ACN, which only applies to registered companies and isn't what we need here.

Brazil — Enter your CNPJ if you're registered as a business (pessoa jurídica), or your CPF if you're operating as an individual (pessoa física).

Canada — Enter your BN (Business Number, 9 digits), along with your GST/HST number if you're registered for it. If you're in British Columbia, Saskatchewan, Manitoba, or Quebec and separately registered for PST, RST, or QST, include that too — these are additional provincial registrations on top of your federal BN.

South Africa — Enter your VAT number, if you're registered. VAT registration isn't mandatory below a certain turnover threshold, so this may be blank if you're not yet registered — that's fine.

Switzerland — Enter your UID (format: CHE-XXX.XXX.XXX). Since 2014, the UID is the single business identifier in Switzerland and replaced the old separate VAT number. If your business is VAT-registered, your VAT number is simply your UID with an added suffix (MWST, TVA, or IVA depending on the region) — so there's no separate number to look for.

United Arab Emirates — Enter your TRN (Tax Registration Number, 15 digits, usually starting with "100"), issued by the Federal Tax Authority.

United Kingdom — Enter your UK VAT number if you have one. As noted above, this won't change your commission (always 0% in the UK), but it keeps your invoices accurate.

Germany — If you have a USt-IdNr (EU VAT number), enter that — this is the number that can be validated through VIES and used for the reverse-charge mechanism. A Steuernummer (local German tax number) is not a VAT number and won't validate through the EU system, so it won't affect your commission even if entered. If you're registered under the Kleinunternehmer scheme (§19 UStG), you're VAT-exempt and typically won't have a USt-IdNr — reach out to us if this is your situation, since it needs to be handled separately.

Italy — Enter your Partita IVA (VAT number) if you're registered as a business — this is what determines whether you get Italy's reduced commission rate. A Codice Fiscale is a personal tax identifier that every resident in Italy has (not exclusive to businesses), so it isn't sufficient on its own to qualify for the reduced rate.

United States — Enter your EIN (Employer Identification Number) if you operate as a business. If you're a non-resident without an EIN, an ITIN may apply instead.
Please do not enter your Social Security Number (SSN) anywhere on the platform. Your SSN is sensitive personal identification and should never be shared with third-party platforms. If the app is asking for a number and only your SSN seems to fit, please reach out to us — we'll help make sure the correct field (EIN or ITIN) is being used instead.

Still not sure which number applies to you?

We're happy to help you figure out the right number for your situation — reach out through the in-app chat. Just keep in mind we're not tax advisors, so for anything specific to your personal tax situation, your local tax authority or an accountant will always be the best source.
