Google Sheets kit · ZZP tax 2026 · version 1.0.0
ZZP Tax and Admin Kit
See how much of each payment is really yours. The kit works out what to keep aside for income tax, Zvw and VAT, tracks your 1,225 hours and checks your invoices against the Dutch rules. It runs in your own Google account and needs no Moneybird.
How to get it. This kit is part of the Dutch Freelancer Bundle (€45 for four kits, €60 when bought separately). It is not sold on its own yet.
What is inside
- Tax reserve: income tax with the 2026 brackets, zelfstandigenaftrek, startersaftrek, MKB-winstvrijstelling, tax credits and Zvw, minus the provisional assessment you already pay.
- Urencriterium tracker: 1,225 hours, pace per week, payroll hours left out, the more-than-half test.
- VAT return boxes per quarter, an ICP reminder and a watch on the €20,000 KOR limit.
- Invoice check against the Dutch requirements, a 12-month cash flow forecast, an hourly rate calculator, a deductible costs guide and checklists for start, contracts, insurance, pension and year end.
- Guides in Dutch and English. Every 2026 figure is listed with its source.
Privacy. The kit runs as Apps Script in your own Google account. It uses no outside service, and nothing passes through our servers.
Not tax advice. The kit gives estimates for planning with the published 2026 figures; the Belastingdienst decides what you pay. Check your own situation with the Belastingdienst or a tax adviser.
Honest limits. The kit is for an eenmanszaak below AOW age. It leaves out a bv, partner, box 2 and 3, depreciation and other deductions, and covers the common VAT cases only. It is a spreadsheet, not accounting software, and it does not file anything.
Test status
The kit uses no outside service. Its sums are checked by 16 automated tests against hand calculations.
