The messiest tax year, made simple

The M-form is the income-tax return for the year you immigrated to or emigrated from the Netherlands. We have the mandate to file it directly, so you never chase the tax office for the form. We sort the resident / non-resident split, file it correctly and explain every step. Taxed abroad on the same income? We check if a tax treaty applies.

You can see how we handle a full return on our page about help with your tax return. Did your 30% ruling start or end that year? That changes your return.
