For many salaried individuals the pay slip is usually just glanced at briefly, if at all. The focus is mostly on the net pay to determine whether rent, fuel, school fees or food shopping will be comfortably covered that month.
You would ignore what sits above that number considering the maze of deductions, reliefs and statutory entries. Within those overlooked lines there are tax reliefs that, if properly understood and claimed, can reduce the amount of pay as you earn (PAYE) deducted every month.
