Module G: Interactive FAQ – Your Tax Questions Answered
What was the standard deduction introduced in Budget 2018?
The Budget 2018 introduced a standard deduction of ₹40,000 for salaried employees and pensioners in lieu of the earlier transport allowance (₹19,200) and medical reimbursement (₹15,000). This was a significant change that simplified tax calculations while providing slightly higher benefits.
For AY 2018-19, all salaried individuals could claim this deduction regardless of their actual expenses, making it a straightforward way to reduce taxable income.
How is HRA exemption calculated for AY 2018-19?
The HRA exemption is calculated as the minimum of these three amounts:
- Actual HRA received from employer
- 50% of salary (for metro cities) or 40% (for non-metro) if living in rented accommodation
- Actual rent paid minus 10% of salary
For example, if your basic salary is ₹50,000/month, you live in Delhi (metro), pay ₹20,000 rent, and receive ₹25,000 HRA:
- Actual HRA: ₹25,000
- 50% of salary: ₹25,000
- Rent paid – 10% salary: ₹20,000 – ₹5,000 = ₹15,000
The exemption would be ₹15,000 (the minimum of the three amounts).
What are the key differences between AY 2018-19 and previous years?
The main changes in AY 2018-19 compared to previous years included:
- Standard Deduction: New ₹40,000 deduction introduced
- Transport Allowance: Discontinued (replaced by standard deduction)
- Medical Reimbursement: Discontinued (replaced by standard deduction)
- Long-term Capital Gains: 10% tax introduced on LTCG exceeding ₹1 lakh from equity shares/mutual funds
- Education Cess: Increased from 3% to 4% (but remained at 3% for AY 2018-19 as the change came in Budget 2018 for AY 2019-20)
- Senior Citizen Benefits: Exemption limit increased to ₹3 lakh (60-80 years) and ₹5 lakh (above 80 years)
- Interest Income: ₹50,000 exemption on interest income for seniors
Note that the long-term capital gains tax on equity was a significant change that affected many investors, though it only applied to gains made after January 31, 2018 (with grandfathering of gains until that date).
How does the calculator handle surcharge and cess?
The calculator applies surcharge and cess as follows:
- Income Tax Calculation: First calculates tax based on applicable slabs
- Surcharge Application:
- 10% surcharge if total income exceeds ₹50 lakh
- 15% surcharge if total income exceeds ₹1 crore
- Education Cess: 3% of (Income Tax + Surcharge)
- Total Tax: Income Tax + Surcharge + Education Cess
For example, if your income tax is ₹10,00,000 and your total income is ₹1,20,00,000:
- Surcharge: 15% of ₹10,00,000 = ₹1,50,000
- Education Cess: 3% of (₹10,00,000 + ₹1,50,000) = ₹34,500
- Total Tax: ₹10,00,000 + ₹1,50,000 + ₹34,500 = ₹11,84,500
What documents should I keep for tax filing in AY 2018-19?

Can I still file my ITR for AY 2018-19 now?
As of 2023, you can still file your ITR for AY 2018-19, but with some important considerations:

For official guidance, refer to the Income Tax Department’s portal or consult a tax professional for complex cases.
How does the calculator handle income from multiple sources?
The calculator is designed to handle composite income from various sources:
- Salary Income: Enter your total salary including all components (basic, DA, HRA, etc.)
- House Property: Include net annual value (rental income minus municipal taxes minus 30% standard deduction)
- Capital Gains: Enter net capital gains (short-term and long-term combined)
- Business/Profession: Enter net profit from business or profession
- Other Sources: Include interest income, dividends, etc.
For accurate results when you have multiple income sources:
- Calculate each income head separately before entering the total
- For house property, only enter the net annual value (not gross rent)
- For capital gains, consider the grandfathering rules for equity LTCG
- Ensure you’ve accounted for all inter-source set-offs (like bringing forward losses)
Note that for very complex income structures (multiple house properties, foreign income, etc.), you might need to consult a tax professional for precise calculations, as the standard calculator assumes certain simplifications.
