A modelling tool for regulated advisers. It recommends no product; the advice remains yours.
Revenue's own worked examples
Revenue's worked examples and its payroll worksheets are reproduced as tests, to the cent, and the free public calculators are used as cross-checks.
Every statutory figure, at its source
Every rate, band, credit and threshold the model uses is listed with the section of the Act that sets it, graded against its primary source, and updated within two weeks of each Finance Act.
Every month closes
The money that moved explains every balance in every month of a traced life, to under half a euro: checked by the tests, and shown in the month-by-month audit.
The verification pack
One simulated life, every tax in every month worked from the law and checked against the ledger, with a data file for a spreadsheet. The one charge it does not yet work line by line is the Fair Deal contribution.
The same answer every time
Each run carries a fingerprint of its inputs, assumptions and engine, and a saved client file reproduces its run exactly. Every change to the model is checked against reference households before and after, and the tests themselves are checked by breaking what they guard. An independent review is planned.
