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.
How it's calculated
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.
Frequently asked
What's a common reason to use this?
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.
Does this account for a second income for married couples?
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.
