Income-tax and Corporate Tax Planning

Income-tax: basics and computation

Income tax is charged on the total income of a person for a previous year, assessed in the following assessment year. Person includes an individual, Hindu undivided family, company, firm, association of persons, body of individuals, local authority and artificial juridical person. Residential status determines scope: a resident is taxed on worldwide income, a non-resident is taxed only on income accruing, arising or received in the country or deemed to accrue or arise there, and a resident but not ordinarily resident occupies an intermediate position for certain foreign income. Residence for an individual turns primarily on days of presence and related conditions, while residence for a company turns on place of effective management and incorporation criteria under the law. Income includes revenue and, where specified, capital receipts, and the charging provision taxes income under five heads, with each head having its own computation rules before aggregation.

Salary income covers wages, allowances, perquisites and profits in lieu of salary, with standard deduction and exemptions for specified allowances such as house rent allowance subject to conditions, and perquisites valued under prescribed rules, including rent-free accommodation, motor car, and other benefits. House property income is computed from annual value, generally the reasonable expected rent, less municipal taxes paid, then a standard deduction for repairs, plus interest on borrowed capital for acquisition or construction subject to limits for self-occupied property, with a self-occupied house generally giving nil annual value subject to interest limits. Profits and gains of business or profession are computed from revenue minus allowable business expenditure, with depreciation on assets, disallowance of personal, capital and certain penal expenditure, and presumptive taxation for eligible small businesses and professionals as a simplified alternative. Capital gains arise on transfer of a capital asset, with short-term or long-term classification depending on holding period, cost of acquisition and improvement, indexed cost where applicable for long-term assets, and exemptions for reinvestment in specified assets such as residential property or specified bonds, subject to conditions and time limits. Income from other sources is the residuary head, covering interest, dividends, family pension and other income not falling under another head, with deductions limited to expenditure incurred to earn that income.

Total income is reached by aggregating head-wise income after clubbing income of a spouse or minor child in specified circumstances, setting off losses within and across heads under prescribed rules, and carrying forward unabsorbed losses such as business loss and capital loss for specified periods to be set off only against income of the same nature where required. Deductions from gross total income, for investments, savings, medical insurance, donations, education loan interest and other specified items, are then allowed subject to limits and conditions, giving total income, which is rounded as prescribed. Tax is computed at rates applicable to the person and regime, with rebate for small total incomes, surcharge on higher incomes, and health and education cess on tax plus surcharge. A minimum alternate tax and alternate minimum tax regime ensures that entities claiming large deductions still pay a minimum, with credit for excess over normal tax carried forward subject to limits. The computation must be done under the regime applicable to the assessee, since old and new regimes differ in deductions and rates, and the choice, where available, should be made by comparing total tax under each, not by habit.

International taxation

International taxation addresses income that touches more than one country. Two principles compete: residence-based taxation, where a country taxes its residents on worldwide income, and source-based taxation, where a country taxes income arising within its territory regardless of residence. When both apply, double taxation arises: the same income is taxed twice. Relief comes through double taxation avoidance agreements, which allocate taxing rights between countries, reduce withholding rates on dividends, interest, royalties and fees for technical services, define permanent establishment, and provide methods of relief, and through unilateral relief where no agreement exists. The agreement method may be exemption, where foreign income is exempt at home, or credit, where foreign tax paid is credited against home tax up to the home tax on that income. Treaty interpretation follows the agreement text, with tie-breaker rules for dual residence and mutual agreement procedures for disputes.

Permanent establishment is the key threshold for business profits: a foreign enterprise is generally taxable in a source country on business profits only if it has a fixed place of business, a dependent agent habitually concluding contracts, or a construction or service presence beyond a threshold period there. Without a permanent establishment, business profits are generally taxable only in the residence country, while other income such as royalties and fees may still be taxed at source at reduced treaty rates. Transfer pricing governs transactions between associated enterprises across borders: prices must be at arm's length, the price unrelated parties would agree, and methods include comparable uncontrolled price, resale price, cost-plus, transactional net margin and profit split methods, chosen by comparability and reliability. Documentation, benchmarking and advance pricing agreements reduce disputes, while adjustments, secondary adjustments and penalties apply where prices are not at arm's length. Base erosion and profit shifting concerns arise where profits are shifted to low-tax jurisdictions through interest, royalties or artificial structures without substance, and responses include general anti-avoidance rules, controlled foreign company rules, limitation of benefits clauses in treaties, and exchange of information between tax authorities. For a business, international tax planning must balance treaty benefits, substance, compliance cost and reputation: a structure with no commercial substance that exists only for tax benefit is vulnerable even if its paperwork is formally correct.

Corporate tax planning

Corporate tax planning is the lawful arrangement of a company's affairs to minimise tax liability within the law, by using exemptions, deductions, incentives, timing and choice of form and financing. It differs from tax evasion, which is illegal concealment or false reporting, and from aggressive avoidance, which exploits loopholes contrary to the spirit of the law and may be defeated by anti-avoidance rules. Good planning starts with business substance: the plan must serve a commercial purpose, be documented, and be capable of withstanding scrutiny. Choice of business form matters: a company offers limited liability and access to capital but faces corporate tax, dividend distribution tax consequences where applicable, and compliance costs, while a partnership or limited liability partnership offers different tax and liability trade-offs, and the form should be chosen for business reasons with tax as one factor, not the only factor.

Financing choice affects tax because interest on debt is generally deductible while dividends on equity are not, giving debt a tax shield, but excessive debt raises distress risk and interest disallowance or thin capitalisation limits may apply, so the optimal financing balances shield against risk. Location choice matters where incentives, special economic zones, backward area benefits, or lower rates for new manufacturing or other specified activities apply, but incentives require genuine activity, employment and investment in the location, not merely a registered address. Depreciation and capital allowances affect timing: accelerated depreciation or additional depreciation for new plant brings tax forward as a saving, improving cash flow and present value even where total depreciation is unchanged. Expenditure planning includes timing of repairs, research, and employee welfare spending that is deductible, while capital expenditure is generally not deductible except through depreciation. Amalgamation and merger planning considers carry forward of losses and unabsorbed depreciation to the amalgamated company subject to conditions on continuity of business and shareholding, and demerger planning considers tax neutrality where conditions on assets, liabilities and shareholders are met. Dividend policy interacts with tax at shareholder level: a company must consider the tax cost to different shareholders, treaty rates for foreign shareholders, and the effect of buy-back versus dividend as a distribution route. Make-or-buy, own-or-lease, and domestic versus export decisions all have tax dimensions: leasing may give deductions to the lessee and depreciation to the lessor, exports may attract incentives or zero rating under indirect tax, and each choice must be evaluated on after-tax cash flow, not pre-tax profit alone.

TDS, advance tax and filing

Tax deducted at source is collection at the point of payment: the payer deducts tax from specified payments such as salary, interest, rent, professional fees, commission and contract payments, at prescribed rates, deposits it with the government, files statements, and issues certificates to the payee, who claims credit against final liability. The system ensures regular collection, widens the tax base, and reduces year-end burden, but it creates compliance duties: correct rate, timely deduction, timely deposit, correct permanent account number quoting, and accurate statements, with interest, fees and penalties for default, and disallowance of expenditure in some cases where tax was not deducted. Tax collected at source applies to specified receipts such as sale of certain goods. The payee must reconcile certificates and the tax credit statement with the return, and any mismatch must be resolved with the deductor rather than ignored, since credit follows the statement.

Advance tax is payment in instalments during the year when estimated liability after tax deducted at source exceeds a prescribed threshold. Instalments fall due on specified dates through the year, with prescribed proportions, and shortfall or deferment attracts interest. Senior citizens without business income are generally exempt from advance tax, and the regime recognises that salaried taxpayers with full deduction at source may need no advance tax. Self-assessment tax is paid with the return to cover any remaining liability. Assessment follows filing: summary processing checks arithmetic and obvious mismatches, scrutiny assessment examines selected returns in detail, best judgment assessment applies where the assessee fails to cooperate, and reassessment may reopen cases where income has escaped assessment within prescribed limits. Appeals proceed through commissioner appeals, tribunal, high court on substantial questions of law, and supreme court, with stays, rectification and revision as additional remedies.

Filing requires choosing the correct return form, reporting income under each head, claiming deductions with evidence, disclosing assets and foreign holdings where required, verifying the return, and responding to notices and defects. Belated returns, revised returns, and updated returns have different time limits and consequences, and failure to file, concealment, or inaccurate particulars attracts penalties and, in serious cases, prosecution. Refunds arise where tax deducted, collected or paid in advance exceeds final liability, and are issued with interest where delayed beyond prescribed time. E-filing, pre-filled data, and annual information statements have reduced errors but not removed the assessee's duty to verify: the return is the assessee's declaration, and reliance on pre-filled data does not excuse omission of income the assessee knew about. Good compliance is therefore a system: maintain books, preserve vouchers, reconcile tax credits quarterly, estimate advance tax honestly, and file on time, so that planning gains are not lost to interest and penalties.
