Detailed Explanation
## What AccountsOS does for a Belgian company
AccountsOS is an AI accountant. Finn does the production work and a person reviews and signs.
## What Finn does
- Keeps the books: bank transactions, receipts and invoices.
- Estimates corporate tax at 25%, or the 20% and 25% split for a qualifying SME.
- Flags the €50,000 director remuneration condition for the SME rate.
- Checks turnover against the €25,000 VAT exemption threshold.
- Calculates VAT at 21%, 12% or 6%, and estimates social security contributions.
- Tracks deadlines: corporate tax, VAT, DmfA, withholding tax, annual accounts, advance payments and Intrastat where relevant.
- Looks up a company by its enterprise number and checks the format.
## What you or your accountant still do
There is no direct e-filing integration with any Belgian authority. You file through the official portals:
- **Corporate tax return:** Biztax, through MyMinfin.
- **VAT returns:** Intervat.
- **Payroll:** the ONSS/RSZ, the TFA portal and DIMONA, usually through a payroll provider.
- **Annual accounts:** the National Bank of Belgium.
Incorporation goes through a notary. AccountsOS does not submit to the Crossroads Bank for Enterprises.
## A note on advice
Finn gives guidance, not legal or tax advice. An accountant should review the return before it is filed.
