Self Assessment calculations depend on the order in which allowances and tax bands are used, as well as reliefs and income types not included here. Payments on account are normally considered where the amount due is at least £1,000 and less than 80% of the tax was collected outside Self Assessment.
For an exact calculation, your complete tax records and personal circumstances should be reviewed.
