AM-bidrag, A-skat and top tax, the mechanics
AM-bidrag: the flat 8% off the top
AM-bidrag (arbejdsmarkedsbidrag, labour-market contribution) is a flat 8% taken from your gross income before anything else is calculated. It funds unemployment benefit, parental leave and sickness benefit. Every other tax layer is calculated on what's left after it. From 2026, employees under 18 are exempt.
A-skat: the withholding tax
A-skat is the income tax your employer withholds each payday, based on your tax card. It bundles bottom tax (12.01%) and municipal tax (~25%) after your monthly allowance. "A" income is employment income taxed at source; "B" income (freelance, some other sources) is not withheld and you handle it yourself.
Top tax: the higher brackets
Since the 2026 reform, the old single top bracket is three:
| Bracket | Rate | Kicks in above (after AM-bidrag) |
|---|---|---|
| Middle tax | 7.5% | ~DKK 641,200 |
| Top tax | 7.5% | ~DKK 777,900 |
| Top-top tax | 5% | ~DKK 2,592,700 |
These stack only on the income above each line - never on your whole salary. The thresholds are measured on personal income after the 8% AM-bidrag is removed.
Putting it together
Order of operations: gross → minus 8% AM-bidrag → minus monthly allowance → bottom + municipal tax on the rest → higher brackets on the top slices. That's your A-skat. See the whole flow on your payslip, or the layered overview in the tax system for beginners.
