A company contribution to your pension is deducted from profit, is not a benefit in kind, and has no income tax, PRSI or USC taken from it. Through a PRSA, the company can pay up to 100% of your salary each year with no benefit in kind. A master trust allows funding based on your salary and service, which for a long-serving director can be more.
The fund grows without tax. At retirement, a quarter of a personal pension fund can come out as a lump sum, the first €200,000 tax free, and the rest is taxed as income when drawn.
