Tax deduction denial for pharmaceutical freebies: expenses excluded under Explanation 1 to Section 37(1) as prohibited by law.
Whether expenditures by pharmaceutical companies for distribution of incentives to medical practitioners are allowable under Section 37(1) depends on Explanation 1 to Section 37(1), which disallows deductions for purposes that are an offence or are prohibited by law; because medical ethics regulations prohibit doctors from accepting such freebies and attach punishments, donors' provision of those incentives is treated as participation in proscribed conduct and such expenses are not allowable as business deductions.

Belated employees' contribution: deduction disallowed when not deposited by prescribed statutory due date; employer contribution treated differently.
Non-deposit of employees' contribution within the due date prescribed under the respective provident/insurance statute results in disallowance of the employer's deduction, whereas employer contributions are subject to a separate payment-based rule that defers deduction until actual payment. The statutory scheme preserves distinct treatment: employee contributions must be credited by the statutory due date to qualify as deduction, while employer contributions may be allowed on a payment basis when actually paid.

Optional personal tax regime clarified with default slab rules, restricted deductions, and surcharge plus cess implications.
Existing special-rate provisions for companies and cooperative societies remain unchanged for AY 2023-24 while Part I of the First Schedule prescribes standard slab rates for other assessees; the optional personal tax regime permits eligible individuals and HUFs to elect alternative slab rates with disallowance of most deductions except specified allowances, procedural rules govern exercise and revocation of the option, and surcharge, marginal relief and a fixed health and education cess apply with specified caps and computation rules.

TDS rates and surcharge framework for the fiscal year set; winnings from online games are subject to withholding at a specified rate.
TDS rates for non-salary incomes for FY 2023-24 remain as in the prior schedule and apply under the specified withholding provisions; the schedule now also covers withholding on online gaming winnings at the rate set in the Bill. Prescribed section rates govern deduction. A multi-tier surcharge regime increases deducted tax by differing rates across taxpayer categories and income bands, with caps limiting surcharge on dividend and specified capital-gains income and an alternative-regime surcharge restriction. Health and Education Cess of four percent applies on tax including surcharge where applicable.

TDS on salaries: prescribed deduction rates and advance-tax computation clarified, with limited change for incomes under section 115BAC.
Part III of the Finance Bill prescribes rates for TDS on salaries and the computation of advance tax for the fiscal year, and those rates also apply when charging tax in provisional or accelerated assessments. The schedules apply across categories of taxpayers-individuals, cooperatives, firms, local authorities and companies-and the overall rate structure remains unchanged except for incomes governed by the alternative optional tax regime; the Bill also notes the continuing framework for tax rebate entitlement.

New Default Tax Regime: revised slab rates apply for individuals and HUFs, with optional alternative regime and surcharge caps.
Default tax rates under section 115BAC(1A) govern income-tax computation for individuals, HUFs, AOPs, BOIs and specified artificial juridical persons for FY 2023-24, with a progressive slab structure; taxpayers may opt under proposed section 115BAC(6) to instead be taxed under the alternative rates in Part III, which set different exemption limits for ordinary residents and senior citizens. The Bill includes a graduated surcharge regime for higher incomes, provides caps on surcharge where income includes dividends or specified capital gains, limits surcharge for AOPs consisting only of companies, and restricts surcharge rates for persons taxed under section 115BAC(1A); marginal relief is provided at surcharge thresholds.

Co-operative society tax rates updated: surcharge tiers retained; new concessional options introduced for qualifying manufacturing societies.
Co-operative societies will continue under the existing income-tax rate structure with a tiered surcharge framework for higher total income and marginal relief. Resident societies satisfying statutory conditions may opt for an optional reduced tax regime with a specified surcharge. Newly established manufacturing co-operative societies that commence production within a prescribed window and do not claim specified incentives may opt into a concessional tax regime for subsequent assessment years, subject to surcharge.

Surcharge on firms applies beyond income threshold, with an upper cap limiting excess tax liability.
The Finance Bill 2023 maintains the existing rate of income-tax for firms and imposes a surcharge on firms whose total income exceeds the statutory threshold; the surcharge is added to income-tax but is capped so that the total tax plus surcharge on income above the threshold does not exceed, by more than the excess income, the income-tax payable on income at the threshold level.

Local authority income-tax rate retained, with a capped surcharge limiting additional liability above the income threshold.
The Finance Bill maintains the existing specified income-tax rate for local authorities and imposes a surcharge on income-tax where total income exceeds a threshold; it caps the combined income-tax and surcharge liability so that the total payable on income above the threshold does not exceed the tax on the threshold amount by more than the excess income.

Company tax rates revised with reduced options for eligible domestic firms, surcharge slabs retained and health and education cess applied.
The Finance Bill 2023 sets primary corporate tax regimes: specified base rates for domestic companies depending on turnover and election into concessional regimes; optional lower-rate regimes remain available subject to conditions. Surcharge rates for domestic and non domestic companies persist at prescribed slabs with marginal relief provided for surcharge; a Health and Education Cess is levied on tax inclusive of surcharge without marginal relief. A new provision fixes its own tax rate while surcharge is applied according to taxpayer status.

Rebate under section 87A expanded to raise the exempt-income threshold for resident individuals under the new tax regime.
Rebate under section 87A grants a 100% rebate of income-tax payable to resident individuals whose total income does not exceed the specified threshold. From assessment year 2024-25 the rebate is extended to resident individuals whose income is chargeable under the proposed new tax regime provision (proposed sub section (1A) of section 115BAC), making them eligible for a full rebate where their total income falls within the revised threshold.

GST Amendments broaden OIDAR taxability, impose statutory time limits for returns/statements, and decriminalise select offences.
The Finance Bill amends the CGST Act to permit composition levy for suppliers transacting through electronic commerce operators, restrict input tax credit by treating specified Schedule III transactions as exempt-supply value and excluding CSR-related credits, clarify retrospective registration exemptions, impose statutory time limits (with conditional extensions) for furnishing outward-supply details, periodic and annual returns and monthly statements by e-commerce operators, introduce penal liability for E-commerce operators for unregistered/composition supplier contraventions, decriminalise certain offences and raise prosecution thresholds, and give retrospective non-supply treatment to specified Schedule III activities; IGST changes broaden OIDAR taxability and revise place-of-supply rules.

NCCD revision on specified cigarettes raises excise incidence under the Seventh Schedule and alters tariff rate application.
Revision of NCCD rates increases per thousand levies on specified HS 2402 cigarette subitems in the Seventh Schedule, effective 2 February 2023 with provisional collection available. Notification No. 05/2023 Central Excise exempts excise duty on blended CNG to the extent of GST paid on contained biogas/compressed bio gas, subject to specified conditions.

Customs Tariff Rationalization: Revised duties, AIDC and SWS adjust tariffs and amend exemption notifications structure.
Amendments limit the two year validity rule for exemption notifications by excluding international agreements, diplomatic privileges, specified schemes and certain import categories; insert a nine month disposal deadline for Settlement Commission applications; clarify that countervailing and anti dumping determinations and reviews must follow rules under the Customs Tariff Act and that appeals lie against such determinations or reviews; and materially revise the First Schedule and related notifications to rationalize Basic Customs Duty rates, adjust tariff entries, and amend AIDC and SWS treatment while extending, discontinuing or rescinding targeted exemptions.

Decriminalisation of liquidator prosecution: no new prosecutions under the provision after the sunset, existing prosecutions continue.
The amendment inserts a sunset clause decriminalising the provision that imposed criminal liability on liquidators for non compliance with distribution obligations: no fresh prosecution may be launched under the provision on or after 1 April 2023, while prosecutions instituted earlier remain unaffected. The change is justified by the government's decriminalisation policy and by the existing Insolvency and Bankruptcy Code regime and oversight that now govern liquidations.

Tax exemption extension for SUUTI permits continued tax-free administration until a notified date, with revised vacation rules.
Proposal amends the UTI Repeal Act, 2002 to extend that no income-tax or other tax shall be payable by the Administrator in relation to the specified undertaking until the period ending on the thirtieth day of September, 2023, and to provide that the Administrator shall vacate office immediately on redemption of all schemes and payment of entire amounts to investors or from a date notified by the Central Government, whichever is earlier.

Omission of redundant tax provisions: repeal of section 88 and specified income exclusions to streamline statutory law.
Proposal to omit a provision relating to rebate on life insurance premia and provident fund contribution-formerly in section 88-on the ground that it was sunsetted and superseded by the deduction regime under section 80C; and to omit specified clauses of section 10 that had already been sunsetted, with the amendments to take effect from the commencement of the next fiscal year beginning 1st April, 2023.

Withholding of refunds: amended set-off and suspension rules let tax authorities withhold refunds pending assessment, limiting additional interest.
Amendments integrate set-off and withholding mechanisms so the tax authority may set off any refund against sums payable after giving written intimation; where part or no amount is set off, the Assessing Officer, with reasons recorded and prior approval of the Principal Commissioner or Commissioner, may withhold the remaining refund while assessment or reassessment is pending if grant of refund would likely affect revenue. Additional interest will not accrue for the period the refund is withheld, while other interest rights remain unchanged.

Charitable donation deduction change removes named funds from eligible list, affecting deduction eligibility from next assessment year.
Amendment omits sub-clauses (ii), (iiic) and (iiid) of clause (a) of sub section (2) of section 80G, removing three named funds from the statutory list of organizations whose donations qualify for allowed deductions, thereby changing deduction eligibility under the approval-based framework.

Denial of exemption for charities and institutions where income-tax returns are not filed within prescribed filing windows.
Amendments clarify that exemptions for charitable, educational and medical entities will be denied if the return of income for the previous year is not furnished within the time allowed under the principal return-filing provisions, requiring returns to be furnished in accordance with the updated-return provisions but within the initial statutory filing windows.
