Income Tax & TDS Calculator on Salary
Comprehensive Guide to Income Tax & TDS on Salary in India (FY 2023-24)
Module A: Introduction & Importance of Income Tax and TDS on Salary
Income tax is a direct tax levied by the Government of India on the income of individuals and entities. For salaried employees, this tax is deducted at source (TDS) by the employer before disbursing the salary. Understanding how income tax and TDS work is crucial for financial planning, tax savings, and compliance with Indian tax laws.
The income tax calculator helps you determine:
- Your exact tax liability based on your salary structure
- How much TDS will be deducted from your monthly salary
- The impact of different tax regimes (old vs new)
- Potential savings through deductions and exemptions
- Your net in-hand salary after all deductions
According to the Income Tax Department of India, over 8.5 crore individuals filed income tax returns in FY 2022-23, with salaried employees constituting the largest taxpayer segment. Proper tax planning can help you optimize your tax outgo while staying fully compliant with tax regulations.

Module C: Formula & Methodology Behind the Calculator
The calculator uses the official income tax slabs and rules as per the Income Tax Act, 1961 for FY 2023-24 (AY 2024-25). Here’s the detailed methodology:
1. Gross Salary Calculation
Gross Salary = Basic + DA + HRA + Special Allowance + Bonuses + Other Components
2. HRA Exemption Calculation (Section 10(13A))
The least of the following is exempt from tax:
- Actual HRA received
- 50% of salary (for metro cities) or 40% (for non-metro)
- Actual rent paid minus 10% of salary
3. Taxable Income Calculation
Taxable Income = Gross Income – (HRA Exemption + Standard Deduction + Chapter VI-A Deductions)
Standard Deduction: ₹50,000 (for both regimes in FY 2023-24)
4. Tax Calculation (Old Regime)
| Income Range | Below 60 years | 60 to 80 years | Above 80 years |
|---|---|---|---|
| Up to ₹2,50,000 | Nil | Nil | Nil |
| ₹2,50,001 to ₹5,00,000 | 5% | 5% | Nil |
| ₹5,00,001 to ₹10,00,000 | 20% | 20% | 20% |
| Above ₹10,00,000 | 30% | 30% | 30% |
5. Tax Calculation (New Regime – Default from FY 2023-24)
| Income Range | Tax Rate |
|---|---|
| Up to ₹3,00,000 | Nil |
| ₹3,00,001 to ₹6,00,000 | 5% |
| ₹6,00,001 to ₹9,00,000 | 10% |
| ₹9,00,001 to ₹12,00,000 | 15% |
| ₹12,00,001 to ₹15,00,000 | 20% |
| Above ₹15,00,000 | 30% |
6. Surcharge Calculation
Applicable on income tax (not on cess):
- 10% if total income > ₹50 lakh
- 15% if total income > ₹1 crore
- 25% if total income > ₹2 crore
- 37% if total income > ₹5 crore
7. Health & Education Cess
4% of (Income Tax + Surcharge)
8. Monthly TDS Calculation
Monthly TDS = (Total Tax Liability – Advance Tax Paid) / 12
Note: Employers typically deduct TDS uniformly across the financial year.

Module G: Interactive FAQ on Income Tax & TDS
How is TDS different from income tax?
TDS (Tax Deducted at Source) is the mechanism through which income tax is collected in advance by your employer. The key differences are:
- Timing: TDS is deducted monthly from your salary, while income tax is your annual liability
- Calculation: TDS is calculated based on your projected annual income, while income tax is calculated on your actual annual income
- Adjustments: If your actual tax liability is less than TDS deducted, you get a refund when filing ITR
- Responsibility: Your employer deducts TDS, while you’re responsible for paying any additional tax or claiming refunds
For example, if your annual tax liability is ₹1,20,000, your employer will deduct ₹10,000 as TDS each month. At year-end, if your actual tax is ₹1,10,000, you’ll get a ₹10,000 refund.
Which tax regime is better for salaried employees?
The choice depends on your income level and ability to claim deductions:
Choose Old Regime if:
- You have significant investments (₹1.5L+ in 80C, ₹1L in 80D, etc.)
- You have a home loan (can claim ₹2L interest deduction)
- You contribute to NPS (additional ₹50K deduction)
- Your income is between ₹7.5L to ₹15L
Choose New Regime if:
- Your income is below ₹7.5L (lower tax rates)
- You have minimal investments/deductions
- You prefer simpler tax filing without proof submissions
- Your income is very high (>₹15L) as surcharge kicks in later
Pro Tip: Use our calculator to compare both regimes with your actual numbers. The break-even point is typically around ₹15L income with ₹3L+ deductions.
How can I reduce my TDS deductions?
You can reduce TDS by:
- Submitting Investment Proofs: Provide proofs of your 80C, 80D, HRA, etc. investments to your employer by their deadline (usually December)
- Declaring Additional Deductions: Inform your employer about other deductions like:
- Education loan interest (Section 80E)
- Disability benefits (Section 80U)
- Donations (Section 80G)
- Using Form 15G/15H: If your total income is below taxable limit, submit these forms to prevent TDS
- Optimizing Salary Structure: Request your employer to restructure your salary to include more tax-free components like:
- Food coupons (up to ₹2,600/month tax-free)
- Gift vouchers (up to ₹5,000/year tax-free)
- Reimbursements (phone, internet, books)
- Spreading Income: If you have additional income (freelancing, rental), consider spreading it across financial years to stay in lower tax brackets
Important: Any excess TDS deducted can be claimed as refund when filing your ITR, but it’s better to get the deduction right to avoid cash flow issues.
What happens if my employer doesn’t deduct TDS correctly?
If your employer deducts:
- Less TDS than required:
- You’ll need to pay the balance as self-assessment tax before filing ITR
- Interest under Section 234B (1% per month) may apply
- You can request your employer to adjust in subsequent months
- More TDS than required:
- You’ll get a refund when you file your ITR
- Refunds typically take 3-6 months to process
- You can check refund status on the Income Tax Portal
What to do:
- Check your Form 16 (Part B) for TDS details
- Verify TDS credits in your Form 26AS (available on TRACES website)
- If there’s a discrepancy, ask your employer for a revised Form 16
- File a grievance with your employer’s finance/HR department
- If unresolved, you can approach the Income Tax Ombudsman
How is income tax calculated for multiple income sources?
If you have multiple income sources (salary, rental, freelancing, etc.), here’s how tax is calculated:
- Aggregate All Incomes: Sum up income from all heads:
- Salary income (after standard deduction)
- House property income (after 30% deduction)
- Business/profession income
- Capital gains (short-term/long-term)
- Other sources (interest, dividends, etc.)
- Calculate Gross Total Income: Sum of all incomes before deductions
- Apply Chapter VI-A Deductions: Subtract eligible deductions (80C, 80D, etc.)
- Calculate Taxable Income: GTI minus deductions
- Compute Tax: Apply tax slabs based on your chosen regime
- Add Surcharge & Cess: If applicable based on income level
- Adjust for TDS/Advance Tax: Subtract any tax already paid
Example: If you have:
- Salary: ₹10,00,000
- Rental income: ₹2,40,000 (after 30% deduction)
- Freelancing income: ₹3,00,000
- Total income: ₹15,40,000
- Deductions: ₹2,00,000 (80C, 80D, HRA, etc.)
- Taxable income: ₹13,40,000
Important Notes:
- Salary income is taxed as per your chosen regime
- Other incomes are taxed at applicable slab rates
- You can set off losses from one head against income from another (with restrictions)
- File ITR-3 or ITR-4 if you have business/profession income
