Complete Guide & Practical Application
Managing financial administration and invoicing as a freelancer, sole proprietor (eenmanszaak), or small business owner in Europe requires precision. The Mileage Reimbursement Calculator is designed to eliminate guesswork and administrative red tape ("rompslomp") by providing deterministic calculations backed by Dutch Tax Administration (Belastingdienst) and EU standards.
Key Legal & Tax Guidelines to Remember
- Belastingdienst Precision: Always use commercial half-up rounding to two decimal places on every line item and VAT subtotal to ensure reconciliation with tax audits.
- Audit Trail Consistency: Invoices and calculation summaries should never be deleted once issued. If changes occur, issue a corresponding Credit Note cross-referencing the original invoice identifier.
- Statutory Retention Period (Bewaartermijn): Under Dutch tax law (Article 52 AWR), all business invoices, timesheets, and expense logs must be retained for at least 7 years (10 years for immovable property).
Common Mistakes & Pitfalls to Avoid
- Subtracting 21% from a gross price: Never calculate reverse VAT by multiplying gross amounts by 0.21. You must divide by 1.21 to find the true net base.
- Confusing Profit Margin with Markup: Margin is profit relative to selling price; markup is profit relative to cost. Misinterpreting these leads to pricing deficits.
- Missing Mandatory Factuureisen: Ensure your KvK number, BTW-id, and client address are clearly visible before dispatching an invoice.
