Will paying into my pension actually reduce my tax bill?

On £20,000 with a 3% pension, this saves you approximately £120 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.

The £50 pension deduction hurts less than it looks because the tax saving (roughly £10/month) partially offsets it.
