My answer is based on the assumption that this is your only pension plan and that you don't have pension savings over £1,250,000. Take a look here
for information on the lifetime pension savings limit and the potential tax charges on the excess over the protected limit.
If you have no income other than the SIPP redemption in 2015/16, you will pay £47,643 in tax. The first 25%, £45,000, of the payout will be tax free leaving £31,785 taxable at 20% (£6,357.00) and £103,215 taxable at 40% (£41,286.00).
You will lose your personal allowance as your income will be over £121,200. You lose £1 of the personal allowance for every £2 of income in excess of £100,000.
I hope this helps but let me know if you have any further questions.
