Full chapter guide

Key formulas

Tax planning
Legal + within letter and spirit of law + genuine commercial purpose
Done in advance and openly, to use deductions, exemptions and lower rates.
Tax management
Compliance: books + TDS + advance tax + returns + assessments + appeals
Aims at avoiding interest, penalty and prosecution.
Tax avoidance
Follows letter of law + defeats its purpose (often artificial or no real business reason)
Not a crime by itself, but exposed to anti-avoidance rules.
Tax evasion
Illegal + deliberate concealment, falsification or suppression
Attracts penalty and prosecution.
Treaty purpose (section 159(3)(b))
Avoid double taxation without creating opportunities for non-taxation or reduced taxation through evasion or avoidance, including treaty-shopping
Shows the statute's stance against abusive arrangements.
Secondary adjustment (section 170)
Primary adjustment of ₹1 crore or more → secondary adjustment; unrepatriated excess money treated as advance; or option to pay additional tax at 18%
A statutory example of a rule that stops profit shifting.
Section 140 deduction
Deduction = 100% × profits and gains derived from the eligible business, for any 3 consecutive tax years out of 10 years from the year of incorporation
Claimed at the assessee's option. Profits of the eligible business only, and the deduction cannot exceed those profits.
Eligible start-up
Company or LLP + incorporated on or after 1 April 2016 but before 1 April 2030 + turnover not above ₹300 crore + certificate from the Inter-Ministerial Board
The turnover limit applies in the tax year relevant to the year of claim. Sole proprietors, partnership firms and others do not qualify.
Eligible business
Innovation, development or improvement of products, processes or services, or a scalable business model with high potential for employment generation or wealth creation
The start-up must be engaged in this business.
Conditions on formation
Not formed by splitting up or reconstruction of an existing business; not formed by transfer of previously used plant or machinery
Previously used plant transferred is ignored if its value is within 20% of the total value of plant and machinery used in the business. Imported plant used only abroad by another person, never used in India and with no depreciation allowed, is not treated as previously used.
Transfer between businesses
Goods or services transferred between the eligible business and another business of the assessee are taken at market value
This stops profit shifting into the deduction-eligible business. For specified domestic transactions, arm's length price applies.
No double deduction
Profits allowed under section 140 cannot be deducted again under other provisions of Part C of the Chapter
Total deduction cannot exceed the profits of the eligible business.
Audit condition
Accounts audited and audit report in prescribed form furnished by the specified date under section 63
Without this, the deduction is not admissible.
Post-tax cost of debt
Kd (post-tax) = Interest rate × (1 − tax rate)
Applies when the company has taxable profit to absorb the interest. With losses, the saving is deferred.
Tax saving on interest
Tax saving = Interest × tax rate
Use the rate given in the question, including surcharge and cess if stated.
Earnings per share
EPS = (EBIT − Interest) × (1 − t) ÷ Number of equity shares
Use to compare financing plans. Preference dividend, if any, is deducted after tax.
Net dividend in shareholder's hand
Net dividend = Dividend × (1 − shareholder's tax rate)
Dividend from a domestic company is taxed at the shareholder's own rate.
Bonus shares: cost and holding period
Cost of bonus shares = Nil; holding period starts from date of allotment
Original shares keep their original cost and holding period.
Capital gain on sale of shares
Gain = Sale price − Cost of acquisition (− transfer expenses)
Whether the gain is short-term or long-term depends on the holding period and the type of asset.
After-tax cost of a deductible expense
Net cost = Expense × (1 − t)
t is the effective tax rate as a decimal. Use for rent, repairs, interest, wages.
After-tax value of a taxable receipt
Net receipt = Receipt × (1 − t)
Applies to sale proceeds and taxable export incentives (section 26(2)(e)).
Tax shield on depreciation
Tax saving = Depreciation × t
Depreciation is non-cash. Only the tax saving is a cash flow.
Net cash cost of buying
Purchase price − PV of (Depreciation × t) − PV of after-tax salvage
Compare with the present value of after-tax lease rentals. Choose the lower. Add the interest tax shield only if the discount rate is not already the after-tax cost of debt; otherwise do not count interest again.
Net cash cost of leasing
PV of Lease rental × (1 − t)
Discount at the after-tax cost of borrowing if not stated.
Shutdown test
Continue if Contribution > Avoidable fixed costs
The test is contribution against avoidable fixed costs. Applying the same (1 − t) to both sides gives the same answer after tax. Unavoidable fixed costs are ignored. Tax on any loss depends on the set-off and carry-forward rules.
Amalgamation loss transfer
Loss of amalgamating company = deemed loss of amalgamated company for the tax year of amalgamation
Applies only to the cases listed in section 116(1) and only if section 116(4) conditions are met.
Amalgamating company conditions
Business run ≥ 3 years; ≥ ¾ of book value of fixed assets held 2 years before amalgamation, held continuously till amalgamation
Both limbs must be satisfied. Section 116(4)(a).
Amalgamated company conditions
Hold ≥ ¾ of book value of assets acquired for ≥ 5 years; continue the business ≥ 5 years; meet prescribed conditions
Failure makes the set-off made earlier taxable in the year of default (section 116(5)).
Demerger loss: directly relatable
Loss/depreciation directly relatable to transferred undertaking → resulting company
Section 116(6)(a).
Demerger loss: not directly relatable
Apportion in the ratio of assets retained : assets transferred
Section 116(6)(b). The share goes to the demerged or resulting company accordingly.
Carry forward cap
Inherited loss carried forward for not more than 8 tax years after the year the loss was first computed for the original predecessor
Section 116(12), for amalgamations or reorganisations effected on or after 1 April 2025.
SEZ unit deduction (section 144)
Deduction = amount calculated as per section 10AA of the 1961 Act, for the years that section would have allowed
Entrepreneur under the SEZ Act, 2005 who begins to manufacture, produce or provide services. Not a fresh formula.
OBU and IFSC deduction (section 147(1))
Deduction = 100% × qualifying income under section 147(3)
Assessee: scheduled bank or foreign bank with an OBU in an SEZ, or an IFSC unit.
Period for OBU (section 147(2)(a))
20 consecutive tax years from the relevant tax year

Period for IFSC unit (section 147(2)(b))
20 consecutive tax years out of 25 years from the relevant tax year, at the assessee's option

Otherwise no deduction.
Export incentive timing (section 278(2))
Taxable in the tax year when reasonable certainty of realisation is achieved

Quick revision

  • Tax planning is lawful, avoidance exploits the law against its intent, and evasion is illegal concealment or misstatement.
  • In any comparison, use after-tax figures and end with a clear recommendation.
  • State your assumptions about tax rates, regime and income level before computing.
  • Tax advantages must never override commercial sense; say so when you recommend.
  • Section 508(1) requires the specified persons to furnish a statement of specified financial transaction or reportable account.
  • Specified financial transactions include purchase, sale or exchange, services, works contracts, investments or expenditure, and loans or deposits, as prescribed.
  • Under section 508(5), a defect found must be rectified within thirty days of intimation, and the authority may extend this on application.
  • An unrectified defect is treated as furnishing inaccurate information (section 508(6)).
  • Under section 508(7), a notice to a defaulter gives up to thirty days to furnish the statement.
  • Under section 508(8), you must report an inaccuracy you discover within ten days.
  • Section 454 penalty after a notice is ₹1,000 per day of continued failure, capped at ₹1,00,000.
  • Section 455(1) penalty is ₹50,000 for inaccurate information or a due diligence failure; section 455(2) adds ₹5,000 per inaccurate reportable account for a reporting financial institution, where the holder's false information caused it.

Common mistakes

  • Treating tax planning and tax management as the same thing. Fix: Remember: planning reduces the tax payable; management ensures correct and timely compliance.
  • Calling tax avoidance a crime. Fix: Say it is not an offence by itself but may be countered by anti-avoidance provisions.
  • Allowing section 140 to a partnership firm or proprietor. Fix: Only a company or an LLP engaged in eligible business can be an eligible start-up. A partnership firm cannot.
  • Giving the deduction for the first three years automatically. Fix: The assessee chooses any three consecutive tax years out of ten years starting from the year of incorporation.
  • Deducting dividend from profit before computing company tax Fix: Dividend is an appropriation of profit after tax. Only interest on borrowed capital reduces taxable profit.
  • Taxing bonus shares as income when received Fix: No income arises on receipt of bonus shares. The tax comes later, on sale, with cost taken as nil.
  • Treating depreciation as a cash outflow, or ignoring its tax shield. Fix: Add it back as non-cash and include only Depreciation × t as a cash saving.
  • Comparing pre-tax figures when tax rates or tax treatment differ between options. Fix: Convert every item to after-tax before comparing, and say so in the answer.
  • Assuming every amalgamation passes losses to the new company. Fix: First check whether the amalgamation is one of the listed types. Then check section 116(4).
  • Mixing up the three-fourths and the time periods between the two companies. Fix: Amalgamating company: three years in business, assets held for the two years before amalgamation. Amalgamated company: five years holding and business continuity.

Exam tips

  • Write distinctions as a point-wise comparison of legality, intent, disclosure and consequence. Examiners can award marks quickly for each point.
  • Add a small rupee example for each concept to turn a recall answer into an application answer.
  • For scenario questions, state your classification first and justify it afterwards.
  • Use statutory language carefully. Section 159(3)(b) and section 170 are safe references; do not add other section numbers unless certain.
  • Do not name cases unless you are sure of the name and holding. A clear statement of the principle is enough.
  • Write the section 140 conditions as a short list. Examiners reward each condition tested against the facts.
  • Always state the numbers exactly: 100%, three consecutive years, ten years, 1 April 2016 to before 1 April 2030, ₹300 crore, 20%.
  • In case questions, end with a clear recommendation and one line on non-tax factors.
