Hi Siva,
TDS - Tax Deduction at Source. Income tax can be from various sources (salary, business, commercial buildings, house rent, etc.). However, TDS is deducted at the source. Examples are provided below:
1. If you receive a salary from a company exceeding 1.5 lakhs, after exemptions are considered, taxable income is calculated, and the tax amount is deducted from the salary at the source. This deduction is known as TDS on salary.
2. Similarly, when you send a commercial rent bill, the shop owner or authority will pay the rent after deducting TDS at 20.6% for companies and 15.4% for non-companies.
I hope this gives you a better understanding. Apart from salary, other sources of income such as rent, income from shares, income from fixed deposits, and income from the sale of goods are aggregated. You should then consult with an auditor for income taxation, pay any remaining tax after subtracting the TDS deducted from the company's payment before the 31st of March, and file the returns in May.
That's all for now.
