Optional simplified tax regime limits specified deductions and restricts loss set-off, with timing and IFSC carve-outs.
The provision creates an optional simplified tax regime for specified persons applying preset slab rates while disallowing a defined list of exemptions, deductions and specified loss set offs; it operates irrespective of other provisions except where expressly carved out, contains deeming rules treating certain losses and depreciation as finally given effect to, provides limited exceptions for IFSC units, and requires taxpayers to elect or withdraw the option within prescribed timelines subject to procedural rules.

Concessional tax regime for new manufacturing companies: elective, time limited option with fixed-rate treatments and strict eligibility.
An elective concessional tax regime permits domestic manufacturing companies to compute tax under a standalone scheme with fixed tax treatments for defined income categories and specified exclusions. Eligibility hinges on incorporation/registration and commencement temporal thresholds, timely exercise of the option which, once exercised, is irrevocable and continues for subsequent years. Failure to meet conditions invalidates the option prospectively. Computation is constrained by sub-section rules that exclude certain deductions and bar set-off of losses or unabsorbed depreciation attributable to excluded deductions, while cross-references determine treatment of capital gains and deemed incomes.

Optional concessional tax regime: companies forgo specified deductions to access a lower flat tax rate, with strict irrevocable election rules.
An optional concessional tax regime permits a domestic company to elect a lower flat rate if it forgoes specified deductions and certain carry-forward reliefs; losses and unabsorbed depreciation attributable to excluded deductions cannot be set off and are deemed given full effect. The election must be made in a prescribed manner by the return due date, is irrevocable and applies to subsequent years, with failure to meet requirements invalidating the option. IFSC Units receive a limited modification preserving certain deductions subject to that provision's conditions.

Concessional tax rate for qualifying manufacturing companies restricted by disallowed deductions and binding election requirement.
An elective regime permits a domestic company incorporated on or after 1 March 2016 and engaged solely in manufacture/production (including related research and distribution) to compute tax at a flat 25% rate if it validly exercises the option in the prescribed manner. The option excludes specified deductions (notably sections 45(2), 47(1)(b), most of Chapter VIII-C except section 146, and sections in section 205(1)(a)-(g)) and bars set-off of earlier losses attributable to those deductions; the provision contains a non-obstante clause while preserving interplay with specified Parts and sections.

Long-term capital gains tax restructured: LTCG segregated and taxed separately while preserving basic exemption and transitional relief.
Clause 197 prescribes segregation of long-term capital gains from other income, taxing non-LTCG income under the normal progressive regime while subjecting LTCG to a separate rate; resident individuals/HUFs may reduce LTCG to preserve the basic exemption to the extent reduced total income falls short of that threshold. A transitional relief for resident individual/HUF transfers of land or building acquired before a specified cutoff requires dual computation-new LTCG method versus an indexed-cost prior-rate computation-and ignores any excess new-regime tax up to the calculated difference. The enacted Act adds a carve-out for non-resident/foreign-company disposals of unlisted or private-company shares excluding section 72(6) set-off.

Tax on GDR income segregates dividend and long term gain streams, taxes them at specified concessional rates.
The provision creates a special tax regime for resident employees of specified knowledge based companies (or their subsidiaries) who receive GDR linked income acquired in foreign currency: dividends on qualifying GDRs are taxed at a prescribed concessional rate, long term capital gains on transfer of such GDRs are taxed at a separate prescribed concessional rate, and the balance of the individual's income is taxed at prevailing rates. GDR income is excluded from gross total income for computing deductions, sole GDR dividend income precludes other deductions, and section 72(6) does not apply to these LTCG computations.

Electronic payment acceptance requirement mandates prescribed digital channels for businesses and professions exceeding the turnover threshold.
The Act mandates that every person carrying on business or profession whose total sales, turnover or gross receipts exceed the turnover threshold in the immediately preceding tax year shall provide facilities to accept payments through prescribed electronic modes in addition to any other electronic modes offered, with specific modes and operational details to be specified by subordinate legislation.

Deeming rule for dividends: economic owner taxed where transfers separate entitlement from legal receipt.
Section 175 deeming rule attributes interest and dividends to the original owner or beneficial holder when securities transactions separate economic entitlement from legal receipt, applies on day to day accrual where beneficial interest existed during a year, operates irrespective of other charging provisions, allows the Assessing Officer to require ownership details, and includes a business of dealing carve out and short term record date anti arbitrage rules that ignore specified losses and adjust cost of additional securities.

Reference to Transfer Pricing Officer centralises arm's length price determination, binding assessments and enabling validated multi year application.
An Assessing Officer, with prior supervisory approval, may refer determination of the arm's length price for international or specified domestic transactions to a designated Transfer Pricing Officer who issues a written order after notice and hearing; that TPO order is binding on the Assessing Officer for computing total income, and an opt in permits validated application of the TPO's determination to the two immediately following tax years subject to prescribed conditions and recomputation procedures.

Arm's length price determination allows limited acceptance of actual transaction price; AO may redetermine ALP after show-cause.
Arm's length price must be determined using specified transfer pricing methods or other Board prescribed methods, selecting the most appropriate method based on transaction nature, functions and prescribed factors. If a single method yields one price that price governs; a notified tolerance permits acceptance of the actual transaction price in specified cases. The Assessing Officer may determine the arm's length price during assessment where documentation, reliability, or compliance with notice requirements is deficient, but must first give the taxpayer a show cause notice before recomputing total income on that basis.

Specified domestic transaction definition narrows domestic related party scope and imposes an aggregate threshold triggering special anti avoidance rules.
Section 164 defines specified domestic transaction for the Chapter on avoidance of tax by enumerating categories of domestic dealings (cross referencing sections 122, 140(9), 140(13), Chapter VIII, section 144 and section 205(4)) and by permitting additional prescribed transactions; each item is subject to exclusion of international transactions and to an annual aggregate materiality threshold that determines applicability.

Associated enterprise definition expands to objective participation and dependence tests, broadening related party compliance risks.
Clause 162 defines associated enterprise by a general participation test (direct, indirect or through intermediaries in management, control or capital, or common persons participating therein) and a non exhaustive deeming list operative at any time during the tax year that includes objective thresholds and indicia such as minimum shareholding, reciprocal holdings, loan exposure relative to book assets, guarantee exposure, appointment control, IP dependence, supply/purchase dependence, family/common control and a residual mutual interest relationship subject to prescription; for specified domestic transactions the definition is expanded to include other units of the assessee and cross referenced persons or enterprises.

Tax rebate for resident individuals: post calculation reduction of tax up to capped amounts with special formula for higher incomes.
A deduction from income tax payable is available to resident individual assessees in specified income bands: tax is computed first and then reduced by a rebate subject to fixed monetary caps; for incomes above the higher threshold a formulaic reduction by the excess income is prescribed, and any deduction is capped so it does not exceed tax payable under the referenced computation provision.

Deduction for interest on deposits: account-type ceilings differ by seniority, with senior citizens' scope including time deposits.
Deduction for interest on deposits permits individuals (distinctly identifying senior citizens) and HUFs to claim limited deductions on interest from deposits with regulated banks, cooperative societies and Post Offices, subject to monetary ceilings and account-type limits: non-senior individuals and HUFs are restricted to interest from savings accounts excluding time deposits, senior citizens are allowed a broader deduction described as applying to savings accounts and expressly including time deposits, and no deduction is permitted where the deposit is held by or on behalf of a firm, association of persons or body of individuals; "time deposits" are defined as deposits repayable on expiry of fixed periods.

Time bound deduction for Producer Companies allows full tax relief for profits from defined member related agricultural activities, subject to sequencing.
A time bound tax incentive allows Producer Companies, as defined in the Companies Act, to claim a full deduction for profits attributable to an eligible business (marketing members' agricultural produce; supplying members with agricultural inputs; processing members' agricultural produce), subject to a turnover ceiling and a sequencing rule that permits the deduction only after other Chapter deductions; the clause omits attribution, anti abuse and procedural rules, creating compliance uncertainty.

Deduction for co-operative societies: specified cooperative income receives preferential tax deductions, subject to governance and computation rules.
Clause 149 permits targeted tax deductions for co operative societies by fully or partially deducting income attributable to enumerated cooperative activities (banking/credit to members, cottage industries, marketing of members' agricultural produce, supply of agricultural inputs, processing without power, collective disposal of members' labour, and fishing/allied activities), supplies by primary societies to federal cooperatives or government entities, inter cooperative investment income, and income from letting godowns; certain non specified activities qualify only up to capped amounts, governance restrictions on voting rights condition some deductions, and cooperative deductions are computed after reducing specified pre existing deductions.

Special tax deduction for North-Eastern undertakings grants full profit exemption for a fixed consecutive period.
A 100% deduction of profits and gains is available to undertakings in specified North-Eastern States for ten consecutive tax years starting from an "initial tax year", contingent on commencement or substantial expansion within a discrete qualifying window, formation and newness-of-plant conditions, exclusions for specified goods and activities, a defined test for "substantial expansion", and exclusivity preventing concurrent Chapter deductions; cross-referenced provisions determine treatment of re-established entities and aggregate duration limits.

Deduction for research donations: tax relief for approved gifts subject to verification and specified exclusions.
Deduction is allowed for donations to approved research associations or educational institutions for scientific or social science/statistical research, contingent on recipient approval and information furnished by the payee to the prescribed income tax authority and subject to the Board's risk based verification; deductions are excluded where the donor has business/profession income or where contributions in cash exceed the prescribed threshold, and deduction is not to be denied solely because recipient approval is later withdrawn.

Pension contribution deduction: employer and individual pension contributions receive tax relief, with caps and deeming rules affecting receipt.
Section 124 allows deductions for employer contributions to Central Government notified pension schemes subject to employer type percentage ceilings and for individual deposits into such schemes subject to an overall statutory cap; parent or guardian deposits for minors are aggregated with the individual cap. The provision defines salary for this purpose to include dearness allowance where employment terms so provide, disallows duplicate deduction where relief was claimed under the related provision, and deems amounts received on closure, opt out, or as annuity taxable in the year of receipt, with limited exceptions for nominee/parent/guardian receipts on death.

Loss carry-forward restrictions: beneficial ownership and voting-power continuity determine entitlement to set off historic losses.
The section restricts carry forward and set off of losses on change in firm constitution, succession other than by inheritance, and change in shareholding of non-public companies unless continuity of beneficial ownership of shares carrying not less than fifty-one percent of voting power is maintained or specified exceptions (death, gift to relative, certain amalgamations/demergers, insolvency resolution plans with opportunity to be heard, tribunal-approved restructuring, relocation, and a start-up carve-out) apply.
