How is HRA exemption calculated for AY 2018-19, and what documents are required?
HRA exemption for AY 2018-19 is calculated as the minimum of these three amounts:
- Actual HRA received: The amount mentioned in your salary slip

What are the most tax-efficient investment options under Section 80C for AY 2018-19?
For AY 2018-19, these were the most tax-efficient 80C options ranked by effectiveness:

| ELSS Funds | ₹1,50,000 | 3 years | 12-15% long-term | High | Young investors with high risk appetite |
| PPF | ₹1,50,000 | 15 years | 7.6% (govt-set) | Low | Risk-averse investors, long-term goals |
| NPS (Tier I) | ₹1,50,000 (additional ₹50,000 under 80CCD) | Until 60 | 9-12% (market-linked) | Medium | Retirement planning, additional tax benefit |

How does the standard deduction of ₹40,000 work, and who is eligible?
The ₹40,000 standard deduction introduced in Budget 2018 works as follows:
Eligibility:
- Available to all salaried individuals and pensioners
- Not available for self-employed professionals or business owners
- Automatically applied—no need for separate documentation
How it works:
- Flat deduction of ₹40,000 from your salary/pension income
- Replaces the previous transport allowance (₹19,200) and medical reimbursement (₹15,000)
- Net benefit: ₹40,000 – (₹19,200 + ₹15,000) = ₹5,800 additional benefit
Calculation Example:
For an employee with:
- Basic Salary: ₹8,00,000
- HRA: ₹2,40,000
- Other Allowances: ₹1,60,000
Previous system (AY 2017-18):
- Taxable Salary: ₹12,00,000 – ₹19,200 (transport) – ₹15,000 (medical) = ₹11,65,800
New system (AY 2018-19):
- Taxable Salary: ₹12,00,000 – ₹40,000 (standard) = ₹11,60,000
Important Notes:
- The standard deduction is over and above other deductions like 80C, 80D, etc.
- For pensioners, it’s deducted from the pension income before calculating taxable income
- No separate proof or investment is required to claim this deduction
- The benefit is automatically reflected in your Form 16

- First approach your employer’s HR/payroll department with evidence

- If you’ve already filed ITR with incorrect TDS, file a revised return
