This regulation applies if the difference for a tax year mentioned in section 59B(1) of TMA (difference between tax contained in a self-assessment and aggregate of payments on account) is payable to the taxpayer.

The Inland Revenue may have regard to the difference in determining the employee’s code for a subsequent tax year under regulation 14 (matters relevant to determination of code).

But the Inland Revenue must not have regard to the difference if the taxpayer objects at the time the return is delivered or subsequently.
