Key Takeaway

Tax Deducted at Source (TDS) is a financial mechanism introduced by the tax department to collect income tax right at the point where income is generated or paid out. Under this system, the payer (employer, bank, tenant, or client) deducts a specified percentage of tax before remitting the remaining payment to the receiver.

TDS applies to various income types including salary payouts, fixed deposit interest, professional fees, contractor payments, commission, and property rent. The deducted tax is remitted directly to the government on behalf of the individual and is reflected as a tax credit in the taxpayer's official Form 26AS / Annual Information Statement (AIS).

If your total annual income falls below the taxable threshold, or if excess TDS has been deducted relative to your actual tax liability, you can claim a 100% refund of the excess TDS by filing your annual Income Tax Return (ITR). Senior citizens and eligible individuals can also submit Form 15G or 15H to prevent bank TDS deductions.

Mathematical Formula

$$TDS\ Amount = Gross\ Payment \times \frac{TDS\ Rate\%}{100}$$

Calculation Examples

If a bank owes you $10,000 in interest on a fixed deposit, and the applicable TDS rate is 10%: - Gross interest owed = $10,000 - TDS rate = 10% - TDS Amount deducted = $10,000 * 0.10 = $1,000 - Net interest credited to your account = $9,000 - Tax credit in Form 26AS = $1,000
