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 £100,000 with a 8% pension, this saves you approximately £3,200 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 8% into my pension?

The £667 pension deduction hurts less than it looks because the tax saving (roughly £267/month) partially offsets it.
