From 6 April 2017 trading income or property income less than £1,000 in a tax year will no longer be taxable.  There will be no need to apply for exemption or declare the income.  For traders with more than £1,000 income but small amount of expenses, they can benefit by ignoring their expenses and instead claiming a flat £1,000 deduction against their income.

This may be useful for occasional lecturing or semi regular selling of surplus produce for example.
