Presumptive taxation for goods carriages simplifies reporting for small fleet owners while limiting deductions and requiring records.
Clause 58 establishes a presumptive basis for computing profits from plying, hiring or leasing goods carriages by applying prescribed per-vehicle rates, permitting declaration of higher actual income, allowing specified partner salary and interest deductions for firms, requiring books and audit where declared income is lower than the presumptive amount, disallowing other deductions against presumptive income, and treating written down value as if depreciation were claimed and allowed.

Presumptive taxation for professionals deems a portion of gross receipts as taxable income, simplifying compliance but restricting deductions.
Clause 58 institutes a presumptive taxation scheme for specified resident professionals, prescribing turnover-based eligibility and deeming taxable income at a fixed proportion of gross receipts or actual profit, whichever is higher. Eligible taxpayers are generally relieved from routine accounting and audit obligations, but must maintain books and undergo audit if they claim profits lower than the presumptive amount. Deductions or losses are not permitted against the presumptive income, and depreciation is to be treated as if claimed and allowed. Certain entity types are excluded from the scheme.

Presumptive taxation scheme differentiates rates by transaction mode and imposes a five-year lock-in to simplify compliance.
Clause 58 permits computation of presumptive income for eligible small businesses and professions with turnover-based eligibility, distinguishes presumptive rates by mode of receipt, allows actual profit to be claimed if higher, mandates books and audit where actual profits are lower and total income exceeds the basic exemption, and imposes a five-year lock-in for continued application of the scheme.
