If I were retired and drawing my pension, can I earn an income from doing some sports coaching too? If so, how much can I earn without it affecting my pension?
There is nothing to stop you both drawing a pension and earning income at the same time. Your pension is treated for tax purposes as if it is earned income. This means after you have used your personal allowance of £11,500, any pension income will be subject to income tax. You can draw on as many pensions and have as many jobs as you like all at the same time, provided you pay any income tax due.
