The formula for determining taxable income is:
Taxable Income = (Gross Total Income) - (Deductions under Chapter VI-A) - (Exemptions)
2. Tax Slabs for 2018-19 (Old Regime)

| Above ₹10,00,000 | 30% | 30% | 30% |
3. Surcharge Calculation
For incomes exceeding ₹50 lakh:
- 10% surcharge on tax for income between ₹50 lakh and ₹1 crore

Module F: Expert Tax Planning Tips for 2018-19
1. Optimizing Section 80C Deductions
- Prioritize ELSS funds – 3 year lock-in with potential 12-15% returns
- Combine instruments – Mix of PPF (safe), ELSS (growth), and NSC (fixed returns)
- Children’s education – Tuition fees up to ₹1,50,000 per child (max 2)
- Home loan principal – Up to ₹1,50,000 (under Section 80C)
2. Maximizing Medical Deductions

- Preventive health checkups – ₹5,000 allowed within 80D limit
- Senior citizen parents – ₹50,000 deduction (vs ₹25,000 for others)
- Critical illness riders – Often overlooked but can provide additional coverage
3. Strategic Use of Capital Gains
- Hold equity investments for over 12 months for LTCG benefits (10% above ₹1 lakh)
- Use capital loss to offset gains (can be carried forward 8 years)
- Consider debt mutual funds for indexation benefits after 3 years
- Time your property sales to maximize exemption under Section 54
4. Business Income Strategies
- Presumptive taxation – 8% of turnover for businesses with turnover ≤ ₹2 crore
- Depreciation planning – Accelerated depreciation for certain assets
- Family as employees – Pay salary to spouse/children (if genuinely working)
- Home office deduction – Portion of rent, utilities if working from home
5. Year-End Tax Planning Checklist
- Verify all Form 16/16A entries match your records
- Check TDS deductions – claim credit for all (Form 26AS)
- Top-up 80C investments before March 31
- Pay advance tax if liable (15% by June 15, etc.)
- Review previous years’ returns for carry-forward losses
- Consider tax harvesting – book losses to offset gains
6. Common Mistakes to Avoid
- Ignoring Form 26AS – Always reconcile with your records
- Last-minute investments – Often lead to poor financial decisions
- Not claiming HRA – Even if living with parents (with proper rent agreement)
- Missing ITR filing – Even with TDS deducted, filing is mandatory if income > ₹2,50,000
- Incorrect bank details – Causes refund delays
Module G: Interactive FAQ Section
What is the last date for filing ITR for 2018-19?
The last date for filing Income Tax Return (ITR) for the financial year 2018-19 (Assessment Year 2019-20) was July 31, 2019 for most taxpayers. However, the department often extends this date – for 2018-19, it was extended to August 31, 2019.
For taxpayers requiring audit, the due date was September 30, 2019. Late filing attracts a penalty of ₹5,000 (₹1,000 if income ≤ ₹5 lakh) under Section 234F.
How is the 4% cess calculated on income tax?
The Health and Education Cess is calculated as 4% of the total of:
- Income tax (as per applicable slab rates)
- Surcharge (if applicable)
Example: If your income tax is ₹1,00,000 and surcharge is ₹10,000 (10%), then:
Cess = 4% × (₹1,00,000 + ₹10,000) = ₹4,400
This cess replaced the previous 3% Education Cess from FY 2018-19 onwards.
Can I switch between old and new tax regimes after filing?
No, the choice between old and new tax regimes for a particular financial year is irreversible once you’ve filed your return. However:
- You can choose differently each financial year
- The choice doesn’t affect previous or future years
- For 2018-19, the new regime was optional – you could stick with the old regime
We recommend using our calculator to compare both regimes before deciding. In our analysis, the new regime benefited taxpayers with income between ₹5-15 lakh the most.
What deductions are allowed under the new tax regime?
Under the new tax regime introduced in 2018-19, most deductions and exemptions were not available. However, these were still allowed:
- Standard Deduction: ₹40,000 (for salaried/pensioners)
- Transport Allowance: ₹1,600/month for differently-abled
- Conveyance Allowance: For official duties
- Professional Tax: As per state laws
All other deductions under Chapter VI-A (80C, 80D, etc.) were not available if you opted for the new regime.
How is income from house property calculated for tax purposes?
Income from house property is calculated as:
Net Annual Value = (Gross Annual Value) - (Municipal Taxes Paid)
Deduct:
- 30% standard deduction
- Interest on home loan (up to ₹2,00,000)
= Taxable Income from House Property
Gross Annual Value is the higher of:
- Actual rent received
- Fair rental value (determined by municipal authorities)
- Notional rent (if self-occupied, generally Nil)
For self-occupied property, the net value is typically Nil (after interest deduction), but you can claim up to ₹2,00,000 for home loan interest.
What documents should I keep for tax filing?
Maintain these documents for at least 6 years from the end of the assessment year:
- Income Proof: Form 16, salary slips, rent agreements
- Investment Proof: 80C (PPF passbook, ELSS statements, etc.)
- Deduction Proof: 80D (insurance premium receipts), 80G (donation receipts)
- Bank Statements: Showing interest income, TDS credits
- Home Loan Documents: Interest certificate from bank
- Capital Gains: Purchase/sale deeds, brokerage statements
- Previous Returns: ITR-V acknowledgments for past 2 years
For business income, additionally maintain:
- Profit & Loss statements
- Balance sheets
- Audit reports (if applicable)
- Stock registers (if trading)
How does the calculator handle income from multiple sources?
Our calculator treats the total income you enter as the aggregate of all your income sources after appropriate adjustments. Here’s how it works:
- Salary Income: Already net of professional tax and standard deduction
- House Property: Should be net annual value (after 30% deduction)
- Business/Profession: Net profit after all expenses
- Capital Gains: Net gains after indexation/exemptions
- Other Sources: Interest income (net of TDS), etc.
For precise calculation when you have multiple complex income sources, we recommend:
- Calculating each head separately first
- Then summing them for the “Total Annual Income” field
- Using the “Deductions” field for Chapter VI-A deductions only
For example, if you have ₹8,00,000 salary, ₹2,00,000 rental income (after 30% deduction), and ₹1,00,000 interest income, enter ₹11,00,000 as total income.
