Many self-employed people pay a bookkeeper €75 to €200 for every quarterly VAT return – or lose hours on the form themselves. The 123 Tax VAT portal does the calculation for you, for € 19,95 a month.
You enter your sales and purchases – or snap a photo of the receipt – and the portal fills in every box of the VAT return, live. When the quarter ends, you check the numbers and approve. We file your return and remind you before every deadline.

Questions
Does the portal file my VAT return?
You approve your return in the portal, and our team files it with the Belastingdienst. A direct connection to the tax office (Digipoort) follows later, so the portal can file it automatically.
Can the portal pay my VAT?
No. The Belastingdienst does not allow automatic collection of VAT. The portal shows the amount, the account number and the deadline – you transfer it yourself with the payment reference.
Which VAT situations does it handle?
21% and 9% VAT, 0% and reverse charge (btw verlegd), sales to EU businesses, exports, purchases from EU and non-EU countries, and private use. Every box of the return, 1a to 5g.
Does it work for a BV?
Yes. The VAT portal works for a sole trader, a VOF and a BV.
What if I use the small business scheme (KOR)?
Then you do not file VAT returns. You can still keep your sales and purchases in the portal, for your annual income tax return.
Can I cancel?
Yes. The monthly plan can be cancelled any time; you keep access until the end of the paid month. The yearly plan runs until the end of the year you paid for.
Why do you check my identity?
Dutch anti-money-laundering law (Wwft) requires us to know who our customers are. You upload your ID once, in the portal.
