Advance Tax Calculator for Companies (AY 2018-19)
Introduction & Importance of Advance Tax Calculation for Companies (AY 2018-19)
Advance tax calculation for companies during Assessment Year 2018-19 represents a critical financial obligation that directly impacts cash flow management, compliance status, and potential interest penalties. Under Section 208 of the Income Tax Act, 1961, companies with tax liability exceeding ₹10,000 in a financial year must pay advance tax in four installments (15% by June 15, 45% by September 15, 75% by December 15, and 100% by March 15).
The significance of accurate advance tax calculation includes:
- Avoiding Interest Penalties: Section 234B (1% per month) and 234C (1% per month for each deferred installment) impose severe penalties for underpayment or delayed payments.
- Cash Flow Optimization: Proper calculation allows companies to align tax outflows with operational cash cycles, preventing liquidity crunches.
- Compliance Certification: Required for Form 3CD (Tax Audit Report) and Form 29B (MAT calculation) filings.
- MAT Considerations: Companies must evaluate whether normal tax (30% + surcharge) or MAT (18.5% of book profits) is more beneficial.
For AY 2018-19, companies faced unique challenges including:
- Transition provisions from MAT to normal tax regime
- Changes in depreciation rates under Income Tax Rules
- Introduction of 4% Health & Education Cess (replacing 3% Education Cess)
- Revised surcharge rates for high-income companies

Formula & Methodology Behind the Calculator
The advance tax calculation follows a structured methodology as prescribed under the Income Tax Act, 1961 and Finance Act, 2017:
Step 1: Calculate Taxable Income
Formula:
Taxable Income = (Total Estimated Income) – (Eligible Deductions) – (Depreciation)
Step 2: Determine Applicable Tax Rate
For AY 2018-19, companies have two options:
-
Normal Tax Regime:
- Base rate: 30% of taxable income
- Surcharge:
- 0% if income ≤ ₹1 crore
- 7% if income > ₹1 crore but ≤ ₹10 crore
- 12% if income > ₹10 crore
- Health & Education Cess: 4% of (tax + surcharge)
-
Minimum Alternate Tax (MAT):
- Base rate: 18.5% of book profits (as per Section 115JB)
- No surcharge applicable on MAT
- Health & Education Cess: 4% of MAT amount
- MAT credit can be carried forward for 10 years
Step 3: Calculate Total Tax Liability
For Normal Tax:
Total Tax = [Base Tax + Surcharge] + 4% Cess on (Base Tax + Surcharge)
For MAT:
Total Tax = [18.5% of Book Profits] + 4% Cess on MAT amount
Step 4: Determine Net Advance Tax Payable
Net Advance Tax = Total Tax Liability – MAT Credit Utilized
Step 5: Installment Schedule
| Due Date | Percentage of Total Tax | Cumulative Percentage |
|---|---|---|
| June 15 | 15% | 15% |
| September 15 | 30% | 45% |
| December 15 | 30% | 75% |
| March 15 | 25% | 100% |

Interactive FAQ: Advance Tax for Companies (AY 2018-19)
What happens if I underpay my advance tax installments?
Under Section 234B, you’ll be charged 1% simple interest per month on the shortfall from the due amount. Additionally, Section 234C imposes:
- 1% per month for deferment of first three installments
- 1% on the shortfall in the last installment (March 15)
For example, if your total tax liability is ₹50 lakh and you pay only ₹30 lakh by March 15, you’ll face:
- Section 234B interest: 1% × ₹20 lakh × 1 month = ₹20,000
- Section 234C interest: Calculated separately for each missed installment
Use our calculator to determine exact installment amounts and avoid penalties.
How do I calculate advance tax if my company has losses from previous years?
Losses from previous years can be set off against current year’s income under these rules:
- Business losses can be carried forward for 8 years (Section 72)
- Depreciation can be carried forward indefinitely
- Speculation losses can only be set off against speculation profits
Calculation Steps:
- Compute current year’s income before set-off
- Apply brought-forward losses in this order:
- Current year’s depreciation
- Brought-forward business losses
- Brought-forward depreciation
- Calculate tax on the resulting taxable income
- Ensure you have proper documentation (Form 3CD, audit reports) to substantiate the loss set-off
Our calculator automatically accounts for loss set-off when you enter negative values in the deductions field (use negative numbers to represent losses).
What are the key differences between MAT and normal tax regime for AY 2018-19?

| Tax Rate | 30% (+ surcharge + cess) | 18.5% (+ cess) |
| Surcharge | 0-12% based on income | Not applicable |

Use our calculator’s regime comparison feature to determine which option is more tax-efficient for your specific financials. The tool automatically calculates both scenarios when you toggle between regimes.
Can I revise my advance tax payments if my income estimates change?
Yes, you can adjust subsequent installments based on revised estimates. The process involves:
- Recomputing Tax Liability: Use updated income projections in our calculator
- Determining Shortfall/Surplus:
- If you’ve overpaid, the excess will be adjusted against future liabilities
- If you’ve underpaid, pay the difference in the next installment plus interest
- Payment Adjustment:
- For September 15 installment: Pay 45% of revised total (minus June payment)
- For December 15: Pay 75% of revised total (minus previous payments)
- For March 15: Pay balance to reach 100%
- Documentation: Maintain records of:
- Original estimates and calculations
- Revised projections with justification
- Challans for additional payments
Important: You cannot reduce previous installments – only adjust future payments. The March 15 installment must cover any shortfall from earlier periods plus interest.
