On a £35,000 salary, your pension tax relief depends on your marginal income tax rate and how your employer's scheme works. Below we show the relief and net cost for a £1,800 gross contribution (approximately 5% of salary) under each of the three main methods.
At £35,000, your marginal income tax rate is 20% (England, Wales and NI, 2026/27). You pay 20% income tax on your earnings above the personal allowance (£12,570). Your pension provider claims this 20% automatically under relief at source — no Self Assessment claim needed.
