## Response Fields
Key fields in the JSON response `data`:
- `salary` — gross monthly salary
- `totalCost` — total employer cost
- `payoutAmountSalary` — take-home pay
- `incomeTaxEmployeeTotalAmount` — total income tax
- `pensionContributionEmployeeTotalAmount` — employee pension
- `personalTaxAllowanceAmount` — tax credit applied
## Caveats
- Tax rates change yearly — defaults are 2025 rates baked into payday.is
- Union fee varies by union (typically 0.7–1.25%)
- Does not account for benefits in kind, car allowance, etc.
- Personal tax allowance is per-person; couples can transfer unused allowance via `SpouseTaxAllowancePercentage`
