Your accounting profit is the starting point.
Understand why a profit and loss statement may need tax adjustments.
Educational guide · Updated 19 September 2026 · FY 2025–26 / AY 2026–27
The quick answer
Accounting profit and taxable business income can differ. Review expenses, depreciation and other tax adjustments rather than applying a slab rate directly to turnover.
Prepare for a P&L review
- Keep sales, purchases and expense records aligned with your accounts.
- Identify personal expenses, capital purchases and potentially disallowed items.
- Separate book depreciation from the tax computation.
- Flag losses and earlier-year adjustments for review.
Using the business calculator
Our individual estimator needs taxable business profit after allowable business adjustments. It does not calculate company or partnership tax, audit eligibility or presumptive income.
