The ultimate 2026 Dutch tax & budgeting guide (with free template)

Every January the Dutch tax brackets, heffingskortingen and toeslagen change by a few percentage points and a few hundred euros here and there — small enough that nobody notices until they try to actually budget with last year's numbers and the math doesn't quite add up. This guide uses the real, current 2026 figures (linked to the Belastingdienst source for each one), with worked examples instead of just a list of rates, plus a free spreadsheet at the bottom that already has the formulas built in.

Box 1: tax on your salary in 2026

Box 1 covers income from work and your home — salary, ZZP profit, benefits, AOW and pension. In 2026 it still has three brackets, and the second and third bracket thresholds moved up more than the first:

Only the slice of income inside each bracket is taxed at that bracket's rate — earning €45,000 doesn't push your whole income into schijf 2, just the €6,117 above the schijf 1 ceiling.

Heffingskortingen: the part that actually determines your net pay

The bracket rates above are before two tax credits (heffingskortingen) are applied — and they're what most "here are the 2026 tax brackets" articles skip, even though they're the reason your effective tax rate is much lower than the sticker rate on the bracket table.

Algemene heffingskorting (general tax credit)

Everyone gets this, and it shrinks as your income rises:

Arbeidskorting (labour tax credit)

This one only applies to income from work, and it's shaped like a hill — it rises steeply, plateaus near its maximum, then phases out slowly:

That's an effective tax rate of about 18.6% on €45,000 gross — nowhere near the 35.75%–37.56% the bracket table alone would suggest, purely because of the two credits above. This is exactly the calculation the spreadsheet template does automatically for any gross salary you enter.

Box 3: tax on savings and investments

Box 3 is the tax on money you've already saved, not money you earn — and it's exactly the kind of number MuntLab's Net Worth page is built to make visible, since it's your savings and investment balances that determine what you owe. In 2026 the tax-free allowance (heffingsvrij vermogen) is higher than 2025, and savings and investments are taxed at different assumed ("fictief") rates of return:

That's the detail almost nobody explains: because the assumed return on pure savings is low (1.28%), holding cash above the threshold costs very little in box 3 tax — €95 a year on €80,000. The moment part of that money moves into "investments" for box 3 purposes (which includes a second property or a joint investment account, not just stocks), it gets taxed at the 6.00% assumed rate instead, which is roughly 4.7× more tax on the same euro. Whether that trade-off is worth it depends entirely on what you'd actually earn — this isn't investment advice, just what the tax difference is.

Zorgtoeslag: are you leaving money on the table?

Zorgtoeslag is a monthly contribution toward your zorgverzekering premium, and it's one of the most under-claimed toeslagen — people assume their income is too high and never check.

Worth noting: it's tested on your total vermogen on 1 January, not just savings — go over the assets threshold on that date and you lose zorgtoeslag for the entire year, not just the months above it.

Two numbers for context

The wettelijk minimumloon (statutory minimum wage, age 21+) is €14.71/hour from 1 January 2026, rising to €14.99/hour from 1 July 2026 — there's no longer a fixed monthly minimum since it depends on your contracted hours. The AOW-leeftijd in 2026 is 67 years for anyone born between 1 March 1957 and 31 December 1960; check the SVB's own calculator for your exact date if you're close to it.

Turning this into an actual monthly budget

Knowing your net income is step one. The number that actually matters for budgeting is what's left after fixed costs, and in the Netherlands those fixed costs are unusually front-loaded compared to other countries — huur or hypotheek, zorgverzekering premie (on top of any zorgtoeslag), and gemeentelijke belastingen all land as large, predictable monthly or annual charges rather than being spread thin.

A simple starting split, using the €3,051/month net example from above:

That 50/30/20 split is a starting point, not a rule — someone with a mortgage and a young family will usually run higher than 50% on vaste lasten, and that's normal. What actually matters is measuring your own three numbers instead of guessing them, which is the one step almost everyone skips.

The spreadsheet is a one-time snapshot — useful for planning this year's budget, but it won't track what you actually spend against it or flag a subscription that crept back in. That ongoing side is what MuntLab does automatically every month from a bank statement export, with no bank login required.
