Blue Umbrella is one of the best-known tax services for expats in the Netherlands: you fill in their online form and their team checks and files your return for €149 (€199 for a family return, prices including VAT, per their published fee list, June 2026). Taxmo takes the self-serve route: you enter your jaaropgaaf and deductions in a guided wizard, see your refund for free, and file directly to the Belastingdienst for a one-time €49 (€79 with Box 2 or Box 3), fiscal partner data included. If you want a human to handle it, Blue Umbrella is a solid choice; if your situation is a salary, a home, and some deductions, you pay roughly a third with Taxmo.
Blue Umbrella charges €149 for an individual return and €199 for a family return (including VAT), with their staff reviewing and filing for you. Taxmo is €49 one-time for a Box 1 return and €79 when Box 2 (substantial interest) or Box 3 (savings and investments) is involved. The refund calculation is free at Taxmo, so you know the outcome before paying, and the accuracy guarantee covers a Belastingdienst penalty up to €500 if a Taxmo calculation error causes it.
The real difference is the model. Blue Umbrella is a service: people check your input and handle correspondence, which is valuable for complex situations (foreign income, US persons, rulings). Taxmo is software: the wizard applies the official brackets, credits, and thresholds automatically, shows the full breakdown per schijf and heffingskorting, and files via Digipoort, the same secure government channel intermediaries use.
Pick Blue Umbrella if you want zero involvement or have a genuinely complex international situation. Pick Taxmo if you can read your jaaropgaaf: a standard employee return takes about 15 minutes, the estimate is free, and filing is €49 with the fiscal partner's details included rather than priced as a separate family tier.
