Tax Calculation at Source (TDS) Under Income Tax Act
Calculate your tax deductions accurately with our premium interactive tool. Get instant results and visual breakdown.
Module A: Introduction & Importance of Tax Calculation at Source (TDS)
Tax Deducted at Source (TDS) is a crucial mechanism under the Income Tax Act, 1961 that ensures regular collection of taxes at the source of income itself. This system was introduced to prevent tax evasion and maintain a steady flow of revenue for the government. When a payer (like an employer or financial institution) makes certain specified payments such as salary, interest, commission, or rent, they are required to deduct a certain percentage of tax before making the payment to the recipient.
The importance of TDS calculation cannot be overstated:
- Government Revenue: Provides a steady cash flow to the government throughout the year rather than waiting for annual tax filings
- Tax Compliance: Reduces the burden of lump-sum tax payments at year-end for taxpayers
- Financial Planning: Helps individuals and businesses plan their finances better with predictable tax outflows
- Reduced Evasion: Minimizes opportunities for tax evasion by collecting taxes at the source
- Documentation: Creates a paper trail of income that can be verified against tax returns
Under Section 192 of the Income Tax Act, employers must deduct TDS on salary payments based on the employee’s estimated annual income. The rates and thresholds for TDS vary depending on the nature of payment and the taxpayer’s status (individual, HUF, company, etc.). For salary income, TDS is calculated based on the projected annual income and the applicable tax slabs for that financial year.

Module C: Formula & Methodology Behind TDS Calculation
The TDS calculation follows a systematic approach based on the Income Tax Act provisions. Here’s the detailed methodology our calculator uses:
1. Gross Income Calculation
Gross Income = Basic Salary + House Rent Allowance (HRA) + Special Allowances + Bonuses + Other Taxable Components
2. Deductions Application
The following deductions are subtracted from gross income to arrive at taxable income:
- Standard Deduction: Flat ₹50,000 (as per Budget 2023)
- Section 80C: Up to ₹1,50,000 (investments in PPF, ELSS, life insurance, etc.)
- Section 80D: Up to ₹25,000 (medical insurance premium)
- Other Deductions: Section 80G (donations), 80E (education loan), etc.
3. Taxable Income Determination
Taxable Income = Gross Income – (Standard Deduction + Section 80C + Section 80D + Other Deductions)
4. Tax Calculation Based on Slabs
The calculator applies the appropriate tax slabs based on the selected regime and age group:
New Tax Regime (Default) – FY 2023-24
| Income Range (₹) | Tax Rate | Below 60 | 60-80 years | Above 80 |
|---|---|---|---|---|
| 0 – 3,00,000 | 0% | Nil | Nil | Nil |
| 3,00,001 – 6,00,000 | 5% | 5% | 5% | 5% |
| 6,00,001 – 9,00,000 | 10% | 10% | 10% | 10% |
| 9,00,001 – 12,00,000 | 15% | 15% | 15% | 15% |
| 12,00,001 – 15,00,000 | 20% | 20% | 20% | 20% |
| Above 15,00,000 | 30% | 30% | 30% | 30% |
The calculator applies these slabs progressively. For example, if your taxable income is ₹7,50,000:
- First ₹3,00,000: Nil
- Next ₹3,00,000 (₹3,00,001-₹6,00,000): 5% of ₹3,00,000 = ₹15,000
- Remaining ₹1,50,000 (₹6,00,001-₹7,50,000): 10% of ₹1,50,000 = ₹15,000
- Total tax before cess: ₹30,000
5. Surcharge Calculation
For high-income individuals, surcharge is applied:
- 10% surcharge if income exceeds ₹50 lakh
- 15% surcharge if income exceeds ₹1 crore
- 25% surcharge if income exceeds ₹2 crore
- 37% surcharge if income exceeds ₹5 crore
6. Health & Education Cess
A flat 4% cess is applied to the total of income tax plus surcharge.
7. Final TDS Amount
Final TDS = (Income Tax + Surcharge) + 4% Cess

Module G: Interactive FAQ on TDS Under Income Tax Act
What is the difference between TDS and income tax?
TDS (Tax Deducted at Source) is a method of tax collection where tax is deducted at the time of payment itself, while income tax is the actual tax liability calculated on your annual income.
Key differences:
- Timing: TDS is deducted throughout the year; income tax is calculated annually
- Purpose: TDS ensures regular tax collection; income tax determines your final liability
- Adjustment: TDS paid can be adjusted against your final tax liability (shown in Form 26AS)
- Refund: If TDS exceeds your tax liability, you get a refund; if less, you pay the balance
For example, if your employer deducts ₹1,20,000 as TDS but your actual tax is ₹1,00,000, you’ll get a ₹20,000 refund when filing ITR.
How is TDS calculated on salary income?
Salary TDS calculation follows these steps:
- Project Annual Income: Employer estimates your annual salary including basic, HRA, allowances, and bonuses
- Apply Deductions: Subtract standard deduction (₹50,000), professional tax, and declared investments (80C, 80D, etc.)
- Determine Taxable Income: Arrive at net taxable income after all exemptions and deductions
- Apply Tax Slabs: Calculate tax based on applicable slabs (varies by regime and age)
- Add Surcharge/Cess: Apply surcharge if income exceeds thresholds, then add 4% health & education cess
- Monthly Deduction: Divide annual tax by 12 for monthly TDS (adjusted if you submit investment proofs later)
Employers use Income Tax Department’s utility for precise calculations.
What happens if TDS is not deducted or is deducted incorrectly?
Both deductors (employers/banks) and deductees (employees/recipients) face consequences:
For Deductors (who fail to deduct TDS):
- Interest: 1% per month from due date to deduction date (Section 201A)
- Penalty: Equal to the TDS amount not deducted (Section 271C)
- Prosecution: Rigorous imprisonment up to 7 years with fine (Section 276B)
- Disallowance: Expense may be disallowed under Section 40(a)(ia)
For Deductees (if TDS is short-deducted):
- You remain liable for the full tax amount
- May need to pay self-assessment tax before filing ITR
- Interest under Section 234B (1% per month) for late payment
- Possible scrutiny notice from Income Tax Department
If TDS is deducted but not deposited:
- Deductor cannot claim this as TDS in your Form 16/26AS
- You’ll need to pay the tax again and claim refund later
- Deductor faces severe penalties including prosecution
Remedy: If you notice TDS discrepancies in Form 26AS, immediately contact the deductor for correction. For errors in salary TDS, submit a request to your employer’s payroll department.
Can I claim refund if excess TDS has been deducted?
Yes, you can claim a refund if excess TDS has been deducted. Here’s the process:
- Verify in Form 26AS: Check all TDS entries in your Form 26AS (available on Income Tax portal)
- File ITR: File your Income Tax Return (ITR) declaring all incomes and TDS details
- Claim Refund: The system automatically calculates refund if TDS exceeds your tax liability
- Bank Validation: Ensure your bank account is pre-validated on the ITR portal for direct credit
- Processing: Typically takes 20-45 days for refund processing
- Track Status: Monitor refund status on the TIN NSDL website
Important Notes:
- Refunds are processed only after ITR verification (e-verification recommended)
- Interest at 0.5% per month is paid if refund is delayed beyond specified periods
- For salary income, first check with your employer if TDS can be adjusted in subsequent months
- Keep all TDS certificates (Form 16, 16A, etc.) as proof
How does TDS work for freelancers and professionals?
For freelancers, consultants, and professionals, TDS works differently than salary income:
Key Provisions:
- Section 194J: TDS at 10% on professional/technical fees (2% for call center operations)
- Threshold: TDS applies if single payment exceeds ₹30,000 (₹1,00,000 for certain cases)
- Form 16A: Clients issue Form 16A (not Form 16) as TDS certificate
- Advance Tax: If total tax liability exceeds ₹10,000, pay advance tax in installments
Compliance Requirements:
- Obtain TAN if you need to deduct TDS from payments to others
- File quarterly TDS returns (Form 24Q for salary, 26Q for others) if you’re a deductor
- Issue TDS certificates (Form 16/16A) to deductees within deadlines
- Pay TDS to government within 7 days from the end of the month of deduction
Tax Planning Tips:
- Maintain proper books of accounts if gross receipts exceed ₹25 lakh (₹10 lakh for professionals)
- Consider presumptive taxation under Section 44AD/44ADA if eligible
- Track all business expenses to reduce taxable income
- Use digital payment methods for better documentation
