Module G: Interactive FAQ
What is the difference between Financial Year (FY) and Assessment Year (AY)?
The Financial Year (FY) is the 12-month period from April 1 to March 31 in which you earn your income. The Assessment Year (AY) is the year following the FY in which you file your income tax return and assess your taxes.
For example:
- FY2019-20 refers to income earned from April 1, 2019 to March 31, 2020
- AY2018-19 would be incorrect – it should be AY2020-21 for FY2019-20
- This calculator is for AY2018-19, meaning it calculates taxes for income earned in FY2017-18
However, there seems to be a confusion in the original request. Typically, AY2018-19 would correspond to FY2017-18. For FY2019-20, the correct AY would be AY2020-21. This calculator follows the tax rules applicable for AY2018-19 (FY2017-18).
How is the standard deduction of ₹40,000 calculated in AY2018-19?
The standard deduction of ₹40,000 introduced in AY2018-19 replaces:
- Transport allowance of ₹19,200 per annum (₹1,600 per month)
- Medical reimbursement of ₹15,000 per annum
Key points about standard deduction:
- Available to all salaried individuals and pensioners
- No need to submit any bills or proofs
- Flat amount regardless of actual expenses
- Not available for non-salaried individuals
- Reduces taxable income directly
Example: If your salary income is ₹8,00,000, after standard deduction it becomes ₹7,60,000 for tax calculation purposes.
What are the key differences between the old and new tax regimes for AY2018-19?
For AY2018-19, only the old tax regime was available. The new concessional tax regime was introduced in Budget 2020 and became applicable from AY2020-21 (FY2019-20).
Key features of the old regime (AY2018-19):
- Multiple deductions and exemptions available (80C, 80D, HRA, etc.)
- Tax slabs remain the same as previous years
- Standard deduction of ₹40,000 introduced
- Cess increased from 3% to 4%
- Rebate under Section 87A available for income up to ₹3,50,000
The new regime (introduced later) offers lower tax rates but without most deductions and exemptions.
How do I claim HRA exemption if I’m living with my parents?
You can claim HRA exemption while living with parents by following these steps:
- Enter into a formal rent agreement with your parents
- Actually pay rent to your parents (transfer to their bank account)
- Maintain rent receipts as proof
- Your parents must declare this rental income in their tax return
- They can claim 30% standard deduction on rental income
Important considerations:
- This arrangement must be genuine – tax authorities may verify
- Parents’ total income may increase, potentially making them liable to file returns
- If parents are in lower tax bracket, this can be tax-efficient for the family
- Keep documentation for at least 6 years in case of scrutiny
What are the tax implications of selling property in AY2018-19?
Capital gains from property sale in AY2018-19 are taxed as follows:
Short-Term Capital Gains (STCG):
- If property sold within 24 months of purchase
- Taxed at your applicable income tax slab rate
- No indexation benefit available
Long-Term Capital Gains (LTCG):
- If property sold after 24 months of purchase
- Taxed at 20% with indexation benefit
- Indexation adjusts purchase price for inflation
- Can claim exemption under Section 54 by reinvesting in residential property
Exemptions Available:
- Section 54: Reinvest in residential property (within 1 year before or 2 years after sale)
- Section 54EC: Invest in specified bonds (within 6 months, max ₹50 lakh)
- Section 54F: For non-residential property (reinvest in residential property)
Example: If you bought property in 2010 for ₹30 lakh and sold in 2018 for ₹1 crore:
- Indexed cost ≈ ₹45 lakh (using CII)
- LTCG = ₹1 crore – ₹45 lakh = ₹55 lakh
- Tax = 20% of ₹55 lakh = ₹11 lakh
- If reinvested ₹1 crore in new property, tax becomes nil under Section 54
How does the 4% health and education cess work in AY2018-19?
The health and education cess in AY2018-19 is calculated as follows:
- Cess rate increased from 3% to 4% (previously 2% education cess + 1% secondary/higher education cess)
- Applied on the total of income tax plus surcharge (if applicable)
- Formula: Cess = 4% × (Income Tax + Surcharge)
Example calculation:
- Income Tax: ₹2,50,000
- Surcharge (10%): ₹25,000 (applicable if income > ₹50 lakh)
- Total before cess: ₹2,75,000
- Cess (4%): ₹11,000
- Final tax liability: ₹2,86,000
Key points:
- Cess is not eligible for any deductions or rebates
- Applies to all taxpayers (individuals, HUFs, companies)
- Funds collected are used for health and education initiatives
- Must be paid even if you qualify for rebate under Section 87A
