Why paytoo much tax?
Large firms hire tax partners by the hour. You shouldn't have to guess. TAXIOR reads your MyMinfin slips and bookkeeping, flags deductions you may have missed, and explains each suggestion before you act.
1.247+ people on the waitlist
Scattered data leaves money on the table
Slips in MyMinfin, invoices in your accounts, VAT in another portal. Nobody lines them up, especially not before the deadline.
Everything lives elsewhere
MyMinfin, Dexxter or Accountable, and separate spreadsheets each tell part of the story. You can't see at a glance what's correct and what's missing.
Deductions get overlooked
Pension saving, flat-rate professional expenses, regional premiums: many levers stay unused because no one has looked at your full file.
Rules pile up
Sole trader or company? Personal income tax, VAT, and corporate tax overlap. The Belgian tax authority won't wait while you sort it out.
Employee, sole trader, or SME
TAXIOR adapts to your situation, from tax slips and deductions to bookkeeping figures and company data.
