By CA Surekha Ahuja
For most taxpayers, tax planning begins with deductions and
exemptions.
For NRIs, Merchant Navy officers, seafarers and overseas
professionals, it begins with a far more important question:
What is your residential status under Section 6 of the
Income-tax Act?
The answer determines whether your foreign salary remains
outside Indian taxation entirely — or whether your global income becomes fully
taxable in India.
A taxpayer earning ₹50 lakh abroad may legally pay tax in
India only on Indian-source income if he qualifies as a Non-Resident. Another
taxpayer with identical earnings may face an entirely different outcome because
of one error in residential status determination.
For AY 2026–27, this means carefully evaluating day-count
rules, RNOR eligibility, deemed residency under Section 6(1A), DTAA
availability, Tax Residency Certificates, Form 10F compliance and the Country
of Residence field in the return — before filing.
This guide explains the law, its practical application and
the mistakes that most commonly trigger demand notices.
Why Residential Status Matters More Than Citizenship
The most important principle to understand upfront: taxability
under Indian law depends on residential status — not citizenship.
An Indian citizen can be a Non-Resident for tax purposes. A
foreign national can become a tax resident of India if the statutory conditions
are met. Citizenship, passport, or domicile do not determine tax liability.

Key rule: Residential status is determined every
financial year independently. Last year's status does not govern the current
year.
Section 6: The Basic Residency Rules
An individual becomes resident in India under Section 6 if
either condition is satisfied:
Condition 1 — Stay in India for 182 days or more
during the financial year.
Condition 2 — Stay in India for 60 days or more
during the year, AND 365 days or more during the preceding four
financial years combined.
Special provisions modify these thresholds for Indian
citizens, Persons of Indian Origin, NRIs and seafarers. Those modifications are
covered below.
Merchant Navy Officers and Seafarers: Special Rules
Residential status for seafarers requires separate analysis
because services are performed across international waters and multiple
jurisdictions simultaneously.
The 184-Day Benchmark
For Merchant Navy officers serving on foreign-going ships,
the operative threshold is 184 days outside India (185 in a leap year):
|
Days Outside India |
Residential Position |
|
184 days or more |
Generally Non-Resident |
|
Less than 184 days |
Further examination required |
Where Non-Resident status is established, foreign salary
earned for services rendered outside India generally falls entirely outside
Indian taxation.
How Days Are Counted
The primary document is the Continuous Discharge
Certificate (CDC), which records sign-on date, sign-off date, vessel
details and voyage particulars. In any scrutiny or dispute, CDC records carry
greater evidentiary weight than passport entries.
One critical point many officers miss: days spent in
Indian territorial waters are treated as days spent in India. This single error
routinely causes seafarers to miscalculate their 184-day count — and lose
Non-Resident status they believed they had.
Budget 2025: Formal Employment Contract Now Required
From AY 2026–27, a formal employment contract is
mandatory to claim the seafarer's residential status exemption. An offer
letter, informal arrangement or verbal understanding no longer qualifies. If
your contract is not formalised, do this before filing.

The 60-Day, 120-Day and 182-Day Rules for General NRIs
For non-seafarers — NRI employees, returning professionals,
investors and Persons of Indian Origin — residential status requires a careful
review of both physical presence and Indian income.

*Subject to the four-year look-back rule.
The Four-Year Look-Back Rule
Many taxpayers focus only on their current year stay. The
law also examines physical presence during the preceding four financial
years. If you have spent 365 or more days in India over those four years
and you are in India for 60 or more days in the current year, you may become
Resident regardless of this year's stay alone.
This is the rule that most commonly catches NRIs returning
for extended family visits.
RNOR: The Valuable Middle Status
RNOR sits between Non-Resident and fully taxable Resident.
For returning NRIs and overseas professionals relocating to India, it provides
a transition period during which foreign income generally remains outside the
Indian tax net.

Section 6(1A): The Deemed Resident Provision
Section 6(1A) was introduced specifically to address Indian
citizens who were not considered tax residents anywhere in the world — most
commonly those working in zero-tax jurisdictions such as Dubai, Bermuda, Panama
or the Cayman Islands.
When Deemed Residency Applies
All three conditions must be satisfied simultaneously:
- The
taxpayer is an Indian citizen
- Indian
income exceeds ₹15 lakh in the financial year (foreign salary is
excluded from this calculation)
- The
taxpayer is not liable to tax in any other country or territory
What "Not Liable to Tax" Means in Practice
This is where many taxpayers make a critical error. A
residence visa, work permit or Emirates ID does not establish foreign
tax residency. The only document that reliably demonstrates foreign tax
liability is a Tax Residency Certificate (TRC) issued by the foreign
country's tax authority.
|

Proof of Tax Residency? |
|
UAE Residence Visa / Emirates ID |
❌ No |
|
Work Permit |
❌ No |
|

❌ No |
|

✅ Yes |
The Important Relief Most People Don't Know
A common and costly misconception: deemed residency
automatically results in global taxation. That is incorrect.
A taxpayer covered by Section 6(1A) is treated as Resident
but Not Ordinarily Resident (RNOR) — not as a fully taxable Resident.

DTAA: When It Is Relevant and When It Is Not
A Double Taxation Avoidance Agreement becomes relevant only
when the same income faces taxation in two jurisdictions simultaneously.
If you are a Non-Resident in India and your foreign salary
is already exempt under domestic law, DTAA is not required — the exemption
operates independently.

What You Need to Claim DTAA Protection

authority, not the embassy
- Form

India has comprehensive treaties with 89+ countries
including UAE, UK, USA, Singapore, Canada, Germany, Australia and Mauritius.
Country of Residence in ITR: The Most Frequently
Mis-Reported Field
Incorrect reporting of Country of Residence is one of the
most common errors in NRI returns — and one of the most consequential.
|
Your Situation |
Country of Residence in ITR |
|

The most expensive mistake: Non-Resident seafarers
without a TRC selecting "India" as their country of residence because
they are Indian citizens. Indian citizenship is not Indian tax residency. If
you are Non-Resident with no TRC, the correct entry is "Not Resident in
Any Country."
Four Case Studies
Case 1: Merchant Navy Officer with UAE TRC
Rajesh is a Merchant Navy officer on a UAE-flagged vessel.
He was outside India for 255 days. Indian income: ₹9 lakh. Foreign salary: ₹24
lakh (credited to NRE account). He holds a UAE Tax Residency Certificate.

Sameer served on a Bermuda-flagged vessel and was outside
India for 235 days. Indian income: ₹17 lakh. Foreign salary: ₹26 lakh. Bermuda
has no income tax. He has no TRC.
|

The key lesson: The days count alone does not
determine status. Section 6(1A) overrides the basic day-count test when Indian
income exceeds ₹15 lakh and there is no foreign tax liability.
Case 3: NRI with US Green Card
Amit holds Indian citizenship and a US Green Card. He was in
India for 100 days. Indian income: ₹11 lakh. Foreign salary: ₹35 lakh. Green
Card holders are automatically treated as US tax residents by the IRS.

- Verify
day count using CDC — sign-on to sign-off
- Account
for days in Indian territorial waters (these count as India days)

foreign salary is credited to NRE account, not savings account
- Determine
correct residential status: NR / RNOR / Deemed Resident
- Select
correct Country of Residence using the matrix above
- File
Form 10F if claiming DTAA benefit
- Disclose
foreign salary in Schedule EI if NR or RNOR
- File
ITR-2 by 31 July 2026
For General NRIs and Overseas Investors
- Calculate
days in India accurately using passport entries
- Apply
the four-year look-back test
- Examine
RNOR eligibility if staying 120 days or more with Indian income above ₹15
lakh
- Obtain
TRC from foreign tax authority where applicable
- File
Form 10F for any DTAA claim
- Review
foreign asset disclosure requirements
- Confirm
residential status before filing — do not assume continuity from prior
year
- File
ITR-2 by 31 July 2026
Six Mistakes That Frequently Trigger Tax Issues
1. Incorrect day counting — Failing to count
territorial waters days or using passport entries instead of CDC leads to wrong
residential status and failed exemption claims.
2. Treating a UAE resident visa as a TRC — Emirates
ID and residence visas are immigration documents. A Tax Residency Certificate
must be obtained separately from the UAE Federal Tax Authority.
3. Ignoring Section 6(1A) — Seafarers working in
zero-tax jurisdictions with Indian income above ₹15 lakh often overlook this
provision entirely and file with incorrect Non-Resident status.
4. Selecting "India" as Country of Residence
without a TRC — Indian citizenship does not mean Indian tax residency.
Without a TRC, Non-Residents must select "Not Resident in Any
Country."
5. Foreign salary credited to a savings account —
Salary in an NRE account carries a clear paper trail supporting the exemption.
A savings account does not, and can invite scrutiny.
6. No formal employment contract — From AY 2026–27,
this is a compliance requirement, not a suggestion. Formalise the contract
before the filing deadline.

For NRIs, Merchant Navy officers, seafarers and globally
mobile professionals, residential status is not merely a disclosure in the
income tax return. It is the legal foundation upon which the taxation of every
rupee of income rests.
The distinction between Non-Resident, RNOR and Resident
determines the taxability of foreign salary, overseas investments and global
income. Equally important are the implications of Section 6(1A), the
availability of DTAA protection through a Tax Residency Certificate and Form
10F, and the accurate reporting of Country of Residence.
Before filing for AY 2026–27, undertake a careful
residential status review — do not rely on assumptions based on citizenship,
visas, passports or last year's filing.
The most important tax question for every NRI and seafarer is not how much income was earned. It is whether the taxpayer was a Non-Resident, RNOR or Resident under Section 6. Every other tax consequence follows from that single answer.
