The Cushon Master Trust uses the Net Pay arrangement for tax relief. This means that you deduct employee contributions before any tax is taken.
For example, Alex pays 20% tax. £10 goes from his wages into his pension pot, before any tax is taken. This reduces his taxable earnings by £10 and he pays £2 less in income tax. This means he has received £2 tax relief from the government. His take-home pay is reduced by £8 but £10 has gone into his pension pot.
