Deduction

“An amount that tax rules allow a taxpayer to subtract when calculating taxable income, reducing the income on which tax is assessed.”

Why deduction matters to a first-time founder

Valid deductions can reduce a business’s tax bill, while unsupported claims can cause reassessments, penalties and interest. Founders need records showing the amount and business purpose. Eligibility, timing and documentation vary by tax, entity type and jurisdiction, so ordinary accounting expense does not guarantee deductibility.

Examples of deduction

A business has ₹10 million of income before tax deductions and incurs ₹2 million of expenses that local rules allow. Taxable income becomes ₹8 million. At a 25% tax rate, the deduction reduces tax by ₹500,000, not by the full ₹2 million spent.

Common misunderstanding

A deduction reduces taxable income, while a tax credit generally reduces tax itself. It is not a refund of the purchase price, and personal or capital spending may be restricted or treated differently. The same cost can also be deductible in one jurisdiction but disallowed in another.

When to use it

Review potential deductions while recording transactions, not only at filing time. Keep invoices, contracts and evidence of business purpose, and apply the rules for the relevant period and jurisdiction. Ask a qualified tax adviser about mixed-use, connected-party, capital or cross-border expenses.
