I understand that the PAYE tax credit is not available to company directors, who are paid by their own companies, as they are regarded as self employed. and therefore not entitled to the PAYE credit. However if two such individuals were to come to an arrangement whereby each one's company hired the other individual, and each company paid the other individual a gross salary of approx €4,300 p.a., this would be subject to the PAYE credit, and therefore largely untaxed in the hands of the individual (tweak the numbers to negate the tax to nil). Two things result: first, each individual will now receive more after tax cash from the gross payment because it comes from another company NOT owned by that individual (than if their own company had paid teh same gross amount to them) and secondly, a small employer's PRSI liability will arise, but this is a good thing, because it keeps the Class A contributions going, which provides much better social welfare benefits than Class S, which provides old age pension only.
