Months 12 to 9 before the relocation: your home country
Every country you leave has its own exit rules. These can include a tax assessment on gains on paper (latent gains), rules that still apply after you leave, and a final tax return. Deal with these first. Document the valuations, list the options to defer tax and plan the departure date in advance. You can read about the usual patterns on the pages per origin country. Your adviser in your home country calculates the exact figures.
Months 9 to 6: the structure
Have the Dutch structure ready before you relocate. The BV and the holding are formed remotely, usually within one week once all documents are complete (see how remote incorporation works). You open the bank account with a prepared file, and the ownership chart is final. If you restructure after you arrive, extra rules apply. If you restructure before, you avoid these rules completely. See the target structure.
Months 6 to 0: the household
Apply to schools, a year ahead where possible. Rent a home first and buy later. Book the appointment to register with the municipality. You find the full checklist in the 90-day sequence. The application for the 30% ruling is filed with your first payroll. You can compare the options for arrival regimes in the comparison of expat tax regimes.
You can set up the company by power of attorney, from any country. This usually happens within one week once all documents are complete. See setting up a BV in the Netherlands from abroad.
Month 1 after: the review
Confirm your tax residence with both countries. Check the tiebreaker rule in the tax treaty once. Set the mix of salary and dividend for the first year. After that, repeat this review every January.
