Section 5 of the Income-tax Act, 2025 — Scope of Total Income: What India Taxes for Residents, RNOR and NRIs

In plain language

What Section 5 actually does

Section 5 is the foundation stone of Indian income tax. Once your residential status is fixed under Section 6, Section 5 tells you which of your incomes India can actually tax. It does not decide the rate — Section 4 (charge of tax) does that. Section 5 only decides the scope: the boundary line around your worldwide earnings that India draws based on where you belong.

The Income-tax Act, 2025 (which replaced the old Income-tax Act, 1961 with effect from 1 April 2026) keeps the same three-limb logic that Indian courts have applied for decades. Only the section numbering and language changed; the principle did not.

The three tests of taxability

Every rupee of income is tested against three questions:

• (a) Received or deemed to be received in India — the first place the money is received matters. If income is first received in India, it is taxable here regardless of where it was earned.
• (b) Accrues or arises, or is deemed to accrue or arise, in India — this is about the source. Salary for work done in India, rent on Indian property, or business income from an Indian operation accrues in India. Section 9 lists incomes that are deemed to accrue in India (business connection, capital asset situated in India, interest, royalty, fees for technical services, etc.).
• (c) Accrues or arises outside India — pure foreign income with no Indian link.

Who it applies to — the scope changes with status

• Resident and Ordinarily Resident (ROR): Taxed on global income — limbs (a), (b) AND (c). Your Dubai salary, US dividends and UK rent are all taxable in India (foreign tax credit under the relevant DTAA may reduce double tax).
• Resident but Not Ordinarily Resident (RNOR): Taxed on Indian income (limbs a and b) and foreign income only if it is derived from a business controlled in India or a profession set up in India. Passive foreign income (foreign salary for foreign work, foreign interest, foreign rent) escapes Indian tax. RNOR is defined in Section 6(13).
• Non-Resident (NRI): Taxed only on income received/deemed received in India OR accruing/deemed to accrue in India (limbs a and b). Foreign income is completely outside India's net.

Key conditions and limits to remember

• An income cannot be taxed twice under this section — if it is caught under "accrual", it is not taxed again merely because it was later remitted or received in India.
• Merely remitting foreign income to India does not make it taxable — remittance is not "receipt". The first receipt is what counts.
• The RNOR carve-out ("business controlled in / profession set up in India") is narrow. A returning NRI who keeps a foreign job or foreign investments generally pays no Indian tax on that foreign income during the RNOR years — usually the first 2-3 years after returning.
• Residential status is decided year by year under Section 6 (basic tests of 182 days, or 60 days + 365 days over four preceding years; ROR needs resident in 2 of 10 prior years AND 730 days in the last 7 years).

How it interacts with other sections

Section 5 works as a chain: Section 6 fixes status → Section 5 fixes scope → Section 7 tells you what counts as "deemed received" → Section 9 tells you what is "deemed to accrue in India" → Section 4 charges tax at the applicable rate. For NRIs, Section 9 is especially powerful because it can pull foreign-signed transactions into the Indian net through a "business connection".

Practical implications

For NRIs, the message is simple: plan your return to India carefully. The RNOR window is a valuable tax break — foreign bank interest, foreign pensions and foreign capital gains stay out of Indian tax while you are RNOR. Once you become ROR, your entire world income becomes taxable in India, so pre-return restructuring (booking gains, timing bonuses) matters. Always check the applicable DTAA and claim foreign tax credit (Form 67) to avoid being taxed twice.
