    The PAYE Calculator is aimed at PAYE Workers, Contractors, and Company Directors in Ireland. The objective of this Windows 10 application is to provide an idea of how much PAYE, USC, PRSI and LPT one could expect to pay annually. Another feature in development is information regarding available tax reliefs that can be claimed and how a tax refund can be claimed annually.
