Frequently asked questions
Quick answers about Taxmo Kantoor, pricing and filing.
What does Taxmo Kantoor cost?
Your first two clients are free. Monthly pricing then starts at €9.95 per client, decreasing to €7.95 for clients 26–75 and €5.95 from client 76 onward. Prices exclude VAT, and the tiers apply progressively. There is no base or activation fee.
Can I use Taxmo only to file a client’s tax return?
Yes. Mark the client as filing-only. They fall outside your monthly client count, and you use prepaid filing credits: €15 per IB return, €25 per VPB return, or 20 credits for €99, 100 for €399 and unlimited for 12 months for €499 (excl. VAT).
What if my client already pays for Taxmo?
A client with their own paid Taxmo subscription costs your firm nothing under the monthly per-client pricing.
Do I need my own PKIoverheid certificate or Becon number?
No. Taxmo submits returns through Digipoort using its own PKIoverheid certificate. If your firm has a Becon number, you can include it with corporate income tax returns.
How do I move from my current bookkeeping software?
Import supported records through CSV or an XAF audit file, and import client lists from Twinfield, Exact, Yuki or Moneybird. Taxmo shows a preview before you confirm, and you can reverse an import batch while the period remains unlocked.
