Module F: Expert Tips for Advance Tax Planning
Do’s:
- Estimate income conservatively – it’s better to pay slightly more advance tax than face interest penalties
- Maintain proper documentation for all deductions claimed
- Use the TIN NSDL portal for advance tax payments
- Consider MAT implications if your company has significant book profits but low taxable income
- Pay through net banking for immediate credit and acknowledgment
- Keep challan counterfoils as proof of payment
- Reconcile advance tax payments with your annual return (ITR-6 for companies)
Don’ts:
- Don’t wait until the last date to make payments – technical issues can cause delays
- Avoid underestimating income to reduce advance tax – interest under Section 234B is 1% per month
- Don’t ignore the installment schedule – late payments attract interest under Section 234C
- Never use incorrect PAN or assessment year details in challans
- Avoid paying advance tax through cash – use electronic modes only
Pro Tips:
- For companies with fluctuating income, use the “provisional” advance tax calculation method
- If you overpay advance tax, you can claim a refund when filing your annual return
- Consider setting up calendar reminders for all advance tax due dates
- For large companies, consult a tax professional to optimize MAT calculations
- Use Form 28A to intimate the Assessing Officer if you’ve paid advance tax but haven’t received credit
Module G: Interactive FAQ
What happens if I don’t pay advance tax for my company?
If your company fails to pay advance tax or pays less than required, you’ll be liable to pay interest under:
- Section 234B: 1% per month on the shortfall from the total tax liability
- Section 234C: 1% per month for deferment of advance tax installments
For example, if your total tax liability is ₹50 lakh and you paid no advance tax, you would owe approximately ₹5 lakh in interest (1% × 12 months × ₹50 lakh) under Section 234B alone.
How is MAT calculated differently from normal tax for AY 2018-19?
MAT (Minimum Alternate Tax) is calculated at 18.5% of “book profits” (as per profit and loss account) plus surcharge and cess. The key differences are:
| Parameter | Normal Tax | MAT |
|---|---|---|
| Calculation Base | Taxable Income (Income – Deductions) | Book Profits (Accounting Profits) |
| Rate | 30% | 18.5% |
| When Applicable | Always | Only if MAT > Normal Tax |
| Credit Utilization | N/A | MAT credit can be carried forward for 10 years |
For AY 2018-19, you pay the higher of normal tax or MAT. Any excess MAT paid can be carried forward as credit against future tax liabilities.
Can I revise my advance tax estimates during the year?
Yes, you can and should revise your advance tax estimates if:
- Your actual income turns out to be significantly different from initial estimates
- You discover additional deductions you can claim
- There are changes in tax laws during the financial year
Simply pay the difference in the next installment. For example, if you paid ₹5 lakh in the June installment but later realize your total liability should be ₹30 lakh (not ₹20 lakh as initially estimated), you would pay:
- September: ₹9 lakh (45% of ₹30lakh) – ₹5lakh already paid = ₹4 lakh additional
- December: ₹22.5 lakh (75% of ₹30lakh) – ₹9lakh already paid = ₹13.5 lakh
- March: ₹30 lakh (100%) – ₹22.5lakh already paid = ₹7.5 lakh
There’s no penalty for paying more than required – you’ll get a refund when filing your annual return.
