Think of Section 5 as the gatekeeper of your tax return — it decides which of your incomes even enter the calculation. Before you can compute tax, you need to know: does India have the right to tax this particular income? That answer depends entirely on your residential status.
There are three residential buckets. A Resident and Ordinarily Resident (ROR) — your typical salaried person who lives and works in India — pays tax on everything: income earned in India, income received in India, AND income earned abroad. Global income, full stop. A Non-Resident (NR) — say, Mr. Rajesh who moved to the US two years ago — pays tax only on income that is received or accrues in India. His US salary? Not India's concern. Now the tricky middle ground: a Not Ordinarily Resident (NOR). This person is technically a 'resident' but was abroad for many years before returning. They get taxed like an NR on foreign income except when that foreign income comes from a business controlled in India or a profession set up in India. If Ms. Iyer is an NOR who runs a Mumbai-based consulting firm but sits in Dubai, her Dubai billings are still taxable in India because the business is controlled here.
The law uses two key trigger words you must memorise: 'received' (money lands in your Indian bank account) and 'accrues or arises' (you've earned the right to receive it, even if payment hasn't happened yet). Section 5 also has two important Explanations to prevent double-counting: just because foreign income appears in an Indian balance sheet doesn't make it 'received in India', and once an income is taxed on accrual basis, it won't be taxed again when cash is actually received. This is frequently tested as a 4-mark or 6-mark question — expect a scenario where you're given an NOR or NR and asked to identify which incomes are includible in total income.
Worked example
Example 1 — Resident (ROR): Mr. Sharma
Mr. Sharma is a Resident and Ordinarily Resident. During PY 2024-25, he earns:
Salary from Indian employer: ₹12,00,000
Rent from a flat in Chennai: ₹3,00,000
Interest from a UK bank account (accrued outside India): ₹80,000
Dividend from a US company (received in India): ₹40,000
Working:
Income
Included?
Reason
Indian salary
✅ Yes
Accrues in India
Chennai rent
✅ Yes
Accrues in India
UK bank interest
✅ Yes
ROR → global income
US dividend
✅ Yes
Received in India
Total Income = ₹12,00,000 + ₹3,00,000 + ₹80,000 + ₹40,000 = ₹16,20,000
---
Example 2 — Not Ordinarily Resident: Ms. Iyer
Ms. Iyer is NOR. During PY 2024-25:
Salary from Indian company: ₹8,00,000
Profit from a business set up and controlled in Singapore: ₹5,00,000
Profit from a business controlled from Mumbai but operated in Dubai: ₹2,50,000
Working:
Income
Included?
Reason
Indian salary
✅ Yes
Accrues in India
Singapore business (controlled in Singapore)
❌ No
NOR + foreign controlled = excluded
Dubai operations (controlled in Mumbai)
✅ Yes
Business controlled in India → taxable
Total Income = ₹8,00,000 + ₹2,50,000 = ₹10,50,000
⚠️ Common exam mistakes
Confusing NOR with NR: Students often apply NR rules to NOR persons. Remember — NOR is still a resident, just with a carve-out for unconnected foreign income. If the foreign income has an India link (business controlled here), it IS taxable for NOR too.
Ignoring the 'deemed' variants: Don't just check if income was actually received or actually accrued in India. Section 5 also covers 'deemed to be received' and 'deemed to accrue or arise' — rules in Sections 7 and 9 create these deemed situations. Forgetting 'deemed' accrual can make you miss income.
Double-counting income: Some students include the same income twice — once on accrual and again when cash is received. Explanation 2 explicitly bars this. Once taxed on accrual basis, it's done.
Treating balance sheet entry as 'received in India': If a foreign income merely appears in an Indian company's books, that alone does NOT make it received in India. Explanation 1 is clear. Don't fall for this trap in theory questions.
Applying ROR rules to NR clients in problems: In a problem, always identify residential status first before deciding which incomes to include. Many students skip this step and include global income for an NR — that's wrong. NR = India-sourced income only.

(1) Subject to the provisions of this Act, the total income of any previous year of a person who is a resident includes all income from whatever source derived which— (a) is received or is deemed to be received in India in such year by or on behalf of such person; or (b) accrues or arises or is deemed to accrue or arise to him in India during such year; or (c) accrues or arises to him outside India during such year: Provided that, in the case of a person not ordinarily resident in India within the meaning of sub-section (6) of section 6, the income which accrues or arises to him outside India shall not be so included unless it is derived from a business controlled in or a profession set up in India. (2) Subject to the provisions of this Act, the total income of any previous year of a person who is a non-resident includes all income from whatever source derived which— (a) is received or is deemed to be received in India in such year by or on behalf of such person; or (b) accrues or arises or is deemed to accrue or arise to him in India during such year. Explanation 1.— Income accruing or arising outside India shall not be deemed to be received in India within the meaning of this section by reason only of the fact that it is taken into account in a balance sheet prepared in India. Explanation 2.— For the removal of doubts, it is hereby declared that income which has been included in the total income of a person on the basis that it has accrued or arisen or is deemed to have accrued or arisen to him shall not again be so included on the basis that it is received or deemed to be received by him in India.
