Dear Supriya,
Salary consists of two parts: 1) Payments and 2) Deductions.
Payment refers to the part for which the Company pays cash as per the commitment, commonly known as Gross Pay. It may be consolidated or divided into components under which a Company makes payment. In the latter case, Basic is usually the compulsory component while the rest depends on the Company. HRA is another common component.
For example, some companies may provide DA, while others may not.
In addition to the above, Loans and Advances, Awards, Settlements, and Compensations are also present if applicable.
The next section is Deductions:
Under this category, all statutory deductions, Recovery of Loans and Advances, Taxes, Awards, and Settlements are present if applicable.
The statutory deductions include Provident Fund (PF) and the Employee State Insurance Act; Taxes usually include Income Tax and Professional Taxes.
Net Pay = Gross Pay - Total Deductions
For details on PF and ESI, please refer to the relevant acts or search this site for further information.
Regards,
SC
