The Netherlands: Etsy will close your shop over a missing VAT number
The Dutch fee schedule is the standard euro-zone one, so the useful material here concerns the two things Etsy can do to a shop that has nothing to do with fees.
The first is the harder one. If you are in the European Union and your sales pass your country's VAT registration threshold, adding a VAT number to your Etsy account is not optional. Etsy's own policy is that a seller who does not comply after its final reminder has selling privileges suspended. This is a compliance requirement enforced by the marketplace, not advice, and it arrives as an interruption to trading rather than as a charge.
The second concerns the platform reporting rules. Etsy must report sellers who pass 30 transactions or EUR 2,000 in a calendar year to the Belastingdienst. A seller who does not supply the information Etsy needs has payouts held and the shop put into vacation mode by Etsy itself, with closure following if the data never arrives.
Both are worth knowing precisely because neither shows up anywhere in a fee calculation.
The reported figure will not match your books
What Etsy files is net of refunds, its own fees and any tax it remitted on your behalf, split by calendar quarter. Your gross sales figure is a different number, and so is the total that reached your bank.
Reported alongside it: name, address, date of birth, tax identification number, VAT number, bank account identifier and the number of transactions. Etsy sends you a summary of what it filed by 31 January, which is worth reading before you file anything yourself.
The schedule, for completeness
Processing is 4% plus EUR 0.30, the transaction fee 6.5%, Offsite Ads 15%: identical to Germany, Ireland and Finland. The Netherlands pays no regulatory operating fee, unlike Britain, France, Spain and Canada, and is not on Etsy's deposit-fee list.
Supplying a VAT number also stops Etsy charging VAT on its own fees, after which you account for it under the reverse charge. That is the ordinary European arrangement, and Ireland is the only country here excluded from it.
As everywhere, Etsy publishes no VAT percentage for its fees, saying only that VAT "may vary". Any Dutch rate you see comes from the Belastingdienst rather than from Etsy.
