Introduction & Importance of Advance Tax for AY 2018-19
Advance tax is the income tax payable in advance instead of a lump sum payment at year-end. For Assessment Year (AY) 2018-19, which corresponds to Financial Year (FY) 2017-18, the Income Tax Department mandates advance tax payments if your tax liability exceeds ₹10,000 in a financial year. This system helps the government maintain a steady cash flow and reduces the burden of year-end tax payments for taxpayers.
Why Advance Tax Matters
- Avoid Interest Penalties: Under Section 234B and 234C of the Income Tax Act, you may incur interest charges (1% per month) for non-payment or short payment of advance tax.
- Cash Flow Management: Spreading tax payments throughout the year eases financial planning compared to a single large payment.
- Legal Compliance: Mandatory for taxpayers with liability exceeding ₹10,000, including salaried individuals with income from sources other than salary.
- Financial Discipline: Encourages better financial planning and budgeting for tax obligations.
For AY 2018-19, the advance tax due dates and payment percentages were:

Expert Tips for Advance Tax Payment in AY 2018-19
Navigating advance tax requirements can be complex. Here are professional tips to optimize your tax payments and avoid penalties:
For Salaried Individuals
- Check TDS Deductions: If your employer deducts TDS that covers ≥90% of your tax liability, you may not need to pay advance tax. Use Form 26AS to verify TDS credits.
- Account for Other Income: Include income from freelancing, rental properties, or capital gains in your advance tax calculation.
- Use Challan 280 Correctly: Select “100 – Advance Tax” as the payment type and “0021 – Income Tax (Other than Companies)” as the tax applicable.
- Save Challan Receipts: Keep counterfoils of all advance tax payments for future reference and IT return filing.
For Business Owners & Freelancers
- Estimate Conservatively: Base your estimates on previous year’s income plus 10-15% growth to avoid underpayment.
- Quarterly Review: Recalculate advance tax every quarter based on actual earnings to adjust for variations.
- Separate Business & Personal: Maintain distinct accounts for business and personal finances to simplify tax calculations.
- Use Presumptive Scheme: If eligible under Section 44AD, you can pay 100% of advance tax by 15th March instead of installments.
For Senior Citizens
- Leverage Higher Exemption: Senior citizens (60-80 years) get ₹3,00,000 exemption; super seniors (>80) get ₹5,00,000.
- Optimize Deductions: Maximize Section 80D benefits (up to ₹50,000 for senior citizens) for medical insurance premiums.
- Interest Income Planning: For FD interest, consider spreading maturities to manage tax liability across years.
- Use Form 15H: Submit to banks to avoid TDS on interest income if your total income is below taxable limit.
General Tips for All Taxpayers
- Pay Early: Paying advance tax early in the financial year helps avoid last-minute rush and potential penalties.
- Use Online Payment: The NSDL portal or your bank’s net banking offers convenient advance tax payment options.

How is advance tax different from TDS and self-assessment tax?
Understanding the differences between these tax payment types is crucial for proper tax planning:
| Aspect | Advance Tax | TDS (Tax Deducted at Source) | Self-Assessment Tax |
|---|---|---|---|
| Definition | Tax paid in installments during the financial year on estimated income | Tax deducted by payer (employer, bank, etc.) at the time of payment | Tax paid on finalized income before filing returns |
| When Paid | Quarterly (June, Sept, Dec, March) | At time of income payment (salary, interest, etc.) | Before filing IT return (usually by July 31) |
| Who Pays | Taxpayer (individuals, businesses) | Deductor (employer, bank, client) | Taxpayer |
| Applicability | If tax liability > ₹10,000 | Mandatory for specified payments (salary, interest, professional fees) | If tax remains after TDS/advance tax |
| Challan Used | ITNS 280 (Type 100) | Various (24Q for salary, 26Q for others) | ITNS 280 (Type 300) |
| Interest for Non-Payment | 1% per month (Sections 234B & 234C) | Deductor liable for penalties | 1% per month (Section 234A) |
How They Work Together:
- TDS is deducted throughout the year by payers
- You pay advance tax in installments on other income
- At year-end, compare total TDS + advance tax with actual liability
- Pay any shortfall as self-assessment tax before filing returns
- Claim refund if TDS/advance tax exceeds liability
Example: If your salary TDS is ₹80,000 and you have ₹30,000 tax on rental income, you should pay ₹30,000 as advance tax in installments.
What documents should I keep for advance tax payments?
Maintaining proper documentation is essential for advance tax compliance and future reference. Keep these records:
Essential Documents:
- Challan Counterfoils: Form 280 receipts with CIN for each advance tax payment
- Bank Statements: Showing tax payment transactions
- Income Proofs:
- Salary slips (Form 16)
- Bank statements showing interest income
- Rental agreements and receipts
- Capital gains statements
- Business income records (for professionals/self-employed)

- Home loan interest certificates (24b)
- Donation receipts (80G)
- Previous Years’ Returns: IT returns for past 2-3 years for reference

Digital Organization Tips:
