VAT and sales tax software for Mollie
Mollie carries a VAT rate on a payment line and checks that your VAT amount matches it. It never decides the rate, the address that says whose rate applies is optional, and its user agreement puts registering, filing and remitting on you. Commenda covers all of it, from EU OSS to all 50 US states.
Trusted by global businesses
Calculate the rate on every payment
A Mollie payment line carries a VAT rate you supply, and the amount has to match it to the cent. Commenda works out the rate instead, across every EU member state and 70+ countries.
Monitor your global exposure
The EU threshold is one number across all your cross-border sales. Commenda measures your Mollie payments against it, and against thresholds in all 50 US states, and tells you at 80%.
Register, file, and remit
Mollie's user agreement makes assessing, collecting, reporting and remitting taxes your responsibility. Commenda registers you and files, OSS and IOSS included.

Calculate taxes globally on Mollie using Commenda
A Mollie payment line takes a VAT rate and a VAT amount that you pass in, and it rejects the line when the two do not agree. Commenda decides the rate. It applies the place-of-supply rule for the sale, the rate in force in the customer's member state, and US state, county, city and district rates where you sell there.
Track your global exposure from Mollie
The EU threshold is 10,000 EUR across your cross-border sales of goods and digital services combined, counted over the current and the preceding calendar year. No threshold monitoring appears in Mollie's documentation. Commenda measures the same payments against it, and against economic and physical thresholds in all 50 US states and 70+ countries, and tells you at 80%.
Automatically remit transactions around the world
Mollie's reporting covers balances, settlements and transactions, and its own help centre says the transactions export is for payment analysis rather than bookkeeping. There is no tax report. Commenda builds the return from the same payments. EU VAT goes out through OSS and IOSS, alongside GST in APAC and Canada and sales tax in all 50 states, with amendments where a period needs correcting.
Manage your customers and exemptions in one place
Mollie asks for a billing address to improve fraud protection and conversion, and only its buy-now-pay-later methods require one. Commenda holds the customer behind the payment, with the tax ID it verified and the system the record came from. For US sales, exemption certificates are collected through a portal, validated on upload, and applied in the states where they are valid.
Consolidation
Why a Mollie payment does not tell you which return it belongs on
Mollie moves the money and reconciles it accurately. A VAT return needs a different set of facts: which country the supply happened in, whether the customer was a business, and how close you are to a registration you do not have yet. Commenda supplies those.
Mollie checks your VAT arithmetic and takes the rate as given
A Mollie payment line takes a VAT rate as a string and a VAT amount as money, and Mollie's reference states that any deviation from the formula between them results in an error. So a wrong rate passes cleanly as long as the amount agrees with it. Mollie's help centre is direct about where the rate comes from: the VAT you charge your customers depends on your situation and the country you are registered in, and your local tax authorities can advise you.
A payment record rarely fixes the place of supply
Billing and shipping address are optional on a Mollie payment, and Mollie describes both as a way to improve fraud protection and conversion. Only alma, in3, klarna, billie and riverty require a billing address, no method requires a shipping address, and Mollie's docs say either field is satisfied by an email address in place of a postal one. Its migration guide recommends sending an address for every payment, and the reason it gives is chargebacks and fraud.
Local payment methods identify the bank and stop there
iDEAL is listed under one available country code, NL, and Bancontact under BE. What a local method records is the payer's bank. Mollie's settlement report carries the consumer's name, bank account and BIC, and no country, no jurisdiction and no tax. That is the file most finance teams reach for at period end.
One ledger behind every channel
Mollie is rarely the only place revenue arrives. A storefront, a marketplace, and a billing platform each connect to one ledger, across 100+ supported integrations. Every transaction carries its origin, its product tax code, and any tax already collected, so marketplace revenue stays separate from revenue that still needs tax. The result is one exposure figure per jurisdiction and one return per period.
What it takes
What VAT compliance takes on Mollie
Mollie publishes a rate per payment method, and no tax feature is priced because none exists to price. What its docs do set out is what each VAT-adjacent capability depends on, and where the responsibility sits.
| What you need | What Mollie gives you | Source |
|---|---|---|
| A VAT rate on a payment line | A string you pass in, for example 21.00. Mollie stores the rate your checkout decided and does not determine it | Create payment |
| A VAT amount Mollie will accept | Exactly the line total multiplied by the rate over 100 plus the rate. Mollie's docs state that any deviation from that formula results in an error | Create payment |
| A billing address on the payment | Optional. Mollie advises providing it to improve fraud protection and conversion, and requires it only for the alma, in3, klarna, billie and riverty methods | Create payment |
| A shipping address on the payment | Optional on every method. Mollie's docs say it should include an email address or a full postal address, so an email address on its own satisfies the field | Create payment |
| Order lines at all | Optional, and required only for the billie, in3, klarna, riverty and voucher methods. Mollie recommends sending them to reduce chargebacks and fraud | Orders to Payments |
| A tax report | Not offered. Mollie's reporting is a balance report, a settlement report, a transactions export, and a bank connection to your accounting software | Reporting |
| Sales data you could file a return from | The settlement export, which carries the consumer's name, bank account and BIC. No country, no jurisdiction, and no tax breakdown of your sales | Settlement report |
| The only VAT figure in your Mollie reports | VAT on Mollie's own fee. The balance report carries a single withheld transaction fees line holding all fees, VAT, and invoice rounding together | Balance report |
| Your own VAT number validated | Checked against VIES, the database of the European tax authorities, and automatically rejected if VIES returns it as invalid. Your customer's number is not checked | Invalid VAT number |
| An e-invoice through the Peppol network | Mollie Invoicing, with you and your customer both based in the Netherlands, Belgium or Germany, and your customer already registered on Peppol | Mollie Invoicing |

Frequently asked questions
No. A Mollie payment line has a VAT rate field and a VAT amount field, and both are values you send. Mollie validates the relationship between them and its docs state that any deviation from the expected formula results in an error, so it will catch a rounding mistake and accept a wrong rate. Its help centre is explicit that the VAT you charge your customers depends on your business situation and the country you are registered in, and directs you to your local tax authorities. Commenda decides the rate instead, from the place-of-supply rule for the sale and the rates in force in the customer's country, across every EU member state and 70+ countries.
Not from the payment record alone. Mollie makes both address fields optional, requires a billing address only for its buy-now-pay-later methods, and accepts an email address in place of a postal one. Where your checkout is a storefront or a billing platform, we read the sale from the system that holds the address and keep the Mollie payment as the money side. Where Mollie is the only source, the mapping is scoped during implementation, and we tell you which sales cannot be sourced rather than assigning them to a country and hoping.
Three things, all adjacent to your return rather than part of it. It carries the VAT rate and amount you set on a payment line or a Mollie Invoicing invoice, and validates the arithmetic between them. It checks your own VAT number against VIES, the European tax authorities' database, and rejects it automatically if VIES returns it as invalid. And it handles VAT on its own fee: 21% applied for Dutch organisations, reverse charged at 0% in Belgium, Germany and France, and 20% for UK businesses signed up with its UK branch. It does not determine a rate, monitor a threshold, register you, file, or remit.
A PDF invoice yes, a Peppol e-invoice only inside three countries. Mollie Invoicing takes a customer, a payment term, products, and a VAT percentage you enter, and can chase the payment for you. E-invoicing through the Peppol network requires you and your customer to both be based in the Netherlands, Belgium or Germany, and Mollie checks whether your customer's VAT or company number is registered on Peppol before it will send. If they are not registered, a PDF by email is the fallback. Commenda covers the return side across 70+ countries, and where a market needs local credentials we use vetted local partners under our coordination.
Custom integration support for your business
Where a Mollie payment carries no address, the sale is usually recorded properly somewhere else. We map which of your systems holds the ship-to record, connect that one alongside Mollie, and tell you plainly which sales cannot be sourced. No engineering work on your side.
Indirect Tax
Monitor nexus exposure, register, file, and remit sales tax and VAT in one platform. Commenda keeps you compliant across 100+ jurisdictions.
