Anatomy of a proper pay slip
A compliant pay slip has three clearly-separated blocks: identification, earnings, and deductions. The identification block names the employer, the employee, the employee ID or code, the designation, and the pay period the slip covers. Ambiguity in any of these fields — for example a slip that does not say which month it is for — makes the slip almost useless as evidence.
The earnings block lists every component of gross pay separately: basic salary, house-rent allowance, medical allowance, transport, bonus, overtime, and any other regular or one-off earnings. The reason components are separated rather than lumped together is tax: many jurisdictions treat different allowances differently for income-tax and social-security purposes.
The deductions block mirrors the earnings block: income-tax withholding, provident fund or social-security contribution, health insurance, professional tax, and any voluntary deductions like loan repayments or union dues. Each is a separate line so both employer and employee can trace exactly what was withheld and why.
