Irish tax, made easier to follow.
Flint helps people in Ireland understand their tax, check for refunds and prepare their next step with confidence.

What Flint does
Many PAYE workers in Ireland pay the wrong amount of tax because a credit was missed, a job changed or a relief was never claimed. Flint turns Revenue’s rules into plain-language guides and a free estimator that shows where every euro comes from.
Customer accounts let you organise each tax year, save calculations and prepare the information you need before claiming through Revenue.
How we work
- Calculations are rule-based and tied to published, year-specific Revenue rates.
- Every guide links to the Revenue guidance it is based on and shows when it was last reviewed.
- Complex circumstances are routed to human review instead of receiving a misleading estimate.
- We never ask for your Revenue myAccount or ROS password.
Who Flint is for
Flint is an online service for people across Ireland. The free estimator currently covers single, Irish-resident PAYE employees under 65 with standard USC. Our guides cover a wider range of credits and reliefs, from rent and health expenses to tuition fees and flat-rate expenses.
Independent from Revenue
Flint is not part of, or affiliated with, the Office of the Revenue Commissioners. Revenue decides your final tax position. Flint’s estimates and guides are general information, not personal tax advice.
