function calculateTax(taxableIncome, ageGroup) {
let tax = 0;
if (ageGroup === 'below-60') {
if (taxableIncome > 1000000) {
tax += (taxableIncome - 1000000) * 0.3;
taxableIncome = 1000000;
}
if (taxableIncome > 500000) {
tax += (taxableIncome - 500000) * 0.2;
taxableIncome = 500000;
}
if (taxableIncome > 250000) {
tax += (taxableIncome - 250000) * 0.1;
}
}
// Similar logic for other age groups
return tax;
}

Module G: Interactive FAQ Section
1. What are the key differences in Tamil Nadu’s income tax calculation compared to other states?
Tamil Nadu follows the central income tax slabs but has specific considerations:
- Metro Classification: Only Chennai is considered a metro city for HRA purposes (50% exemption), while other cities like Coimbatore, Madurai get 40% exemption
- Profession Tax: Tamil Nadu levies profession tax (₹2,500 max annually) which is deductible from taxable income
- State Surcharge: For incomes above ₹1 crore, Tamil Nadu adds a 1% surcharge on the central tax
- Local Body Tax: Some municipal corporations levy additional taxes that may affect net income
Our calculator automatically accounts for these state-specific rules when processing Tamil Nadu employer calculations.
2. How does the calculator handle the standard deduction for 2016-17?
For financial year 2016-17, the standard deduction was not yet reintroduced (it was brought back in 2018). However, the calculator includes:
- Transport Allowance: ₹1,600/month (₹19,200 annually) exemption
- Medical Reimbursement: ₹15,000 annual exemption
- Conveyance Allowance: ₹800/month (₹9,600 annually) for transport
These are automatically factored into the taxable income calculation when you enter your gross salary.
3. What documents should employers collect from employees for accurate tax calculation?
Employers must collect and verify these documents annually:
- Form 12BB: Employee declaration of investments and expenses
- Investment Proofs:
- PPF passbook

4. How does the calculator handle income from multiple employers?
The calculator is designed to handle complex scenarios:
- Multiple Form 16s: Enter the total income from all employers in the gross income field
- TDS Already Deducted: The calculator shows the total tax liability – you’ll need to subtract TDS already deducted by previous employers
- Relief under Section 89: For arrears received, use our separate arrears calculator then add the relieved amount here
- Different Pay Periods: Annualize all income components before entering
Example: If an employee worked with Employer A (₹6L income, ₹30K TDS) and Employer B (₹8L income), enter ₹14L as gross income. The calculator will show ₹1,20,000 total tax – subtract the ₹30K already deducted to determine additional TDS required.
