Will paying into my pension actually reduce my tax bill?
Yes — if you use salary sacrifice (the most common workplace pension method), your pension contribution of £8,000/year is deducted from your gross pay before tax is calculated. On £40,000 with a 20% pension, this saves you approximately £1,600 in Income Tax per year. In other words, not all of the pension contribution comes out of your pocket — the taxman effectively subsidises part of it.
What will I see in my bank account each month if I pay 20% into my pension?
On a £40,000 salary with 20% going into your pension, your monthly take-home is £2,160. Each month your payslip deducts: Income Tax £324, National Insurance £183, and pension contribution £667. The £667 pension deduction hurts less than it looks because the tax saving (roughly £133/month) partially offsets it.
