Calculate your gross income. This is the sum of your basic salary and any allowances
you receive. Allowances can include commissions, bonuses, overtime, and other
emoluments.
Calculate your allowances. This includes any additional income you receive on top of
your basic salary, such as commissions, bonuses, overtime, and other emoluments.
Add any employer deductions. These could be deductions for a payday loan or credit,
if any. These are subtracted from your gross income.
Calculate NAPSA. This is a mandatory contribution to the National Pension Scheme
Authority and is calculated as 5% of your gross earnings. The maximum contribution
is capped at a certain amount which changes every year.
Subtract the NAPSA contribution from your gross income. This gives you the amount of
income after the NAPSA deduction.
Take note of your income after the NAPSA deduction. This is the amount of income
that is subject to further deductions or contributions.
Calculate other statutory contributions if applicable. These could include NHIMA,
Workers Compensation, etc. Each of these contributions has its own calculation rules
and rates.
Subtract these other statutory contributions from your income after the NAPSA
deduction. This gives you the net income after all deductions and contributions.
