Accuracy in reporting. Discipline in compliance. Confidence under scrutiny.
A Tax Audit under Section 44AB of the Income-tax Act, 1961 is a statutory examination of accounts conducted to ensure that income, deductions, and compliance requirements are correctly reported. It is not merely a certification requirement—it is a regulatory validation of financial discipline and tax accuracy.
At Calculus, Tax Audit engagements are executed with structured review methodologies, analytical verification, and documentation rigor to ensure full compliance and defensibility before the Income Tax Department.
Applicability of Section 44AB
Threshold-based compliance with statutory consequences.
Tax Audit becomes mandatory when turnover, gross receipts, or professional receipts exceed prescribed limits under the Act. It may also apply in cases where presumptive taxation provisions are not opted for or are withdrawn under specified conditions.
- Businesses crossing prescribed turnover limits must undergo audit.
- Professionals exceeding gross receipt thresholds are subject to audit compliance.
- Taxpayers declaring income lower than presumptive limits under relevant sections may trigger audit applicability.
- Specific cases involving deductions or special provisions may also require audit.
Failure to comply may attract penalties under Section 271B, subject to reasonable cause provisions.
