Corporate tax calculator
Enter sales, purchases, expenses, TDS and advance tax to compute taxable income and corporate tax under §115BAA (22% + surcharge + cess, effective rate about 25.168%). For domestic companies, whether the 25%/30% base rates apply depends on prior financial year turnover or gross receipts (commonly tested against the ₹400 Crore threshold), plus surcharge and cess. MAT/AMT, §115BAB applicability and legislative changes need separate review.
Illustrative calculation
1. Rates used in this calculator (illustration under §115BAA)
Rows (i)–(l) simplify the optional regime under the Income-tax Act Section 115BAA (22% base rate). This page illustrates that regime with a simplified stack: 22% base tax + 10% surcharge on that tax + 4% cess on tax plus surcharge. Real-world limits on deductions and brought-forward losses follow the statute and official guidance.
- (i) Corporate tax = max(0, taxable income) × 22%
- (j) Surcharge = (i) × 10% Whether surcharge applies, and at what rate, depends on taxable income, total-income slabs and company characteristics. (For this §115BAA illustration we fix surcharge at 10% of corporate tax (i).)
- (k) Health & education cess = ((i) + (j)) × 4%
- (l) Gross tax = (i) + (j) + (k). Per rupee of taxable income the combined burden is about 22% × 1.10 × 1.04 ≈ 25.168% (22% × 1.10 × 1.04 compresses the same illustration · 22% base, 10% surcharge on that tax, then 4% cess on tax plus surcharge; your effective rate will differ if surcharge does not apply.)
2. Domestic company base rates · prior financial year turnover / gross receipts (₹400 Crore threshold)
Under the general regime where §115BAA is not opted for, whether the 25%/30% base rates apply depends on the prior financial year’s turnover or gross receipts. Rates may change with amendments and interpretation · confirm with MSV.
- Prior financial year turnover / gross receipts ≤ ₹400 Crore: the 25% corporate tax rate commonly applies.
- Prior financial year turnover / gross receipts > ₹400 Crore: the 30% rate commonly applies.
- In addition to the 25% or 30% tax, surcharge applies to the tax amount depending on total income (e.g. roughly 7% if taxable income is between ₹1 Cr and ₹10 Cr, and 12% above ₹10 Cr · verify for the relevant year).
- Health & education cess at 4% is levied on corporate tax plus surcharge, so all-in effective rates often fall roughly in the high twenties to mid-thirties depending on slabs.
§115BAB (15% for new manufacturing), MAT/AMT, mergers & acquisitions and cross-border issues are not modelled here.
Results are illustrative; reported tax can differ with reliefs, brought-forward losses, MAT/AMT and surcharge positions.
