Which tax band applies and what relief you get

On a £125,000 income you are a higher-rate taxpayer paying 40% on income above £50,270 — your personal allowance is also reduced by the £100k taper. Your marginal income tax rate is 40%.

Under relief at source, your provider claims 20% basic rate relief automatically from HMRC. You claim the additional 20% extra relief via Self Assessment — totalling £2,480 on a £6,200 contribution.

Under salary sacrifice, your gross salary is reduced by £6,200 before income tax and National Insurance are calculated. This saves you income tax and employee NI (saving an additional £124), bringing your effective net cost down to £3,596. Your employer also saves NI of £930 — some employers pass this saving into your pension.
