Compare two income scenarios side by side — different salary, tax category, or employment type — to see exactly how the take-home pay differs and why.
Each scenario runs independently through the same Income Tax, USC, and PRSI calculation, then the two results are shown together so the difference in take-home, and in each individual tax component, is directly visible.
Comparing a job offer against your current salary, checking the actual gain from a promotion, or seeing how much married-couple tax bands change the picture versus filing as an individual — anywhere you have two concrete numbers to weigh against each other.
Yes — the married (two incomes) category combines both incomes against a standard rate band of €53,000 plus a non-transferable increase capped at the lower earner's own income (up to €35,000, so up to €88,000 combined) — genuinely different from simply doubling the single-income band, so it's worth comparing married-one vs married-two directly if only one spouse currently earns.
