For India’s estimated 240,000+ active seafarers and merchant navy professionals, one question dominates tax planning every year: how many days have I spent outside India, and am I a non-resident? The answer determines whether their entire ship salary-often credited directly to an Indian bank account-is taxable in India or completely exempt.
The Income Tax Act, 2025 (effective 1 April 2026) consolidates the seafarer residential status framework under Section 6(6), and the detailed computation method is prescribed in Rule 8 of the Draft Income Tax Rules, 2026 (replacing old Rule 126, introduced by Notification 70/2015). The rule uses Continuous Discharge Certificate (CDC) dates to determine the period spent outside India during eligible voyages-a critical mechanism that can turn days spent on an Indian-origin ship into “days outside India” for residential status purposes.
This guide explains the day-counting methodology, eligible voyage definition, CDC mechanics, the 182-day threshold, the 120-day/Rs 15 lakh interaction, the NOR safety net, NRE account treatment, and practical examples. For seafarers managing income tax return filing (https://www.patronaccounting.com/income-tax-return), getting the day-count right is the difference between zero tax and full global income taxation.
How Rule 8 Computes Period of Stay
Rule 8 of the Draft IT Rules, 2026 provides a specific exclusion mechanism:
Sub-rule (1): For an Indian citizen who is a member of the crew of a foreign-bound ship, the period of stay in India during the tax year shall not include the period computed under sub-rule (2) in respect of an eligible voyage.
Sub-rule (2): The excluded period begins on the date entered in the CDC for joining the ship for the eligible voyage and ends on the date entered in the CDC for signing off from the ship in respect of that voyage.
Sub-rule (3) - Definitions:
- Continuous Discharge Certificate (CDC): As defined under the Merchant Shipping (Continuous Discharge Certificate-cum-Seafarer’s Identity Document) Rules, 2001 under the Merchant Shipping Act, 1958.
- Eligible voyage: A voyage undertaken by a ship engaged in the carriage of passengers or freight in international traffic, where (i) the voyage originates from an Indian port and has a foreign port as its destination, or (ii) the voyage originates from a foreign port and has an Indian port as its destination.
Practical effect: If a seafarer joins a ship at Mumbai port on 1 May (CDC date) and signs off at Singapore on 15 November (CDC date), the entire period from 1 May to 15 November (199 days) is excluded from the count of days spent in India-even though the ship may have been in Indian coastal waters for part of this voyage. The seafarer needs only to have spent less than 182 days in India during the remaining days of the tax year (i.e., the days not covered by CDC periods).
Residential Status Decision Tree for Seafarers
Under the IT Act, 2025 (Section 6), a seafarer’s residential status is determined as follows:
| Days in India (after Rule 8 exclusion) | Indian Income | Residential Status | Tax Consequence |
|---|---|---|---|
| < 182 days | Any amount | Non-Resident (NRI) | Only Indian income taxable. Ship salary for services outside India: exempt. |
| 120-181 days | ≤ Rs 15 lakh | Non-Resident (NRI) | Same as above. Ship salary exempt. |
| 120-181 days | > Rs 15 lakh | Resident but NOR | Only Indian income taxable. Ship salary for services outside India: still exempt (NOR protection). |
| ≥ 182 days | Any amount | Resident (ROR or NOR depending on preceding years) | If ROR: global income taxable. If NOR: only Indian income taxable. |
Key insight for seafarers: Even if you trigger the 120-day/Rs 15 lakh rule and become a “resident,” the NOR (Not Ordinarily Resident) classification protects your foreign ship salary from Indian taxation. You become ROR (Resident and Ordinarily Resident) only if you were resident in India in 2 out of the preceding 10 years AND have been in India for 730+ days in the preceding 7 years. Most active seafarers will not meet these conditions.
CDC Dates vs Passport Dates: Which to Use?
This is one of the most common sources of confusion-and litigation-for seafarers:
| Scenario | Dates to Use | Rule/Authority |
|---|---|---|
| Ship joined and signed off at foreign ports | Passport stamping dates (departure from India to return to India) | Passport dates control when CDC covers only the ship period, not the travel to/from the port |
| Ship joined at Indian port, signed off at foreign port (or vice versa) | CDC dates (joining date to signing-off date in the CDC) | Rule 8 / old Rule 126 / Notification 70/2015 |
| Multiple voyages in a tax year | Compute each voyage separately using the applicable date method, then aggregate days outside India | Rule 8 applies per eligible voyage; total days computed by summing all voyages |
Important: At the time of assessment scrutiny, the IT Department cross-verifies CDC dates with passport dates. Maintaining both documents accurately is critical. For seafarers using tax audit services (https://www.patronaccounting.com/tax-audit) or professional filing services, providing both the CDC and passport to the tax professional ensures accurate day-counting.
Salary in NRE Account: Is It Taxable?
One of the biggest relief provisions for NRI seafarers is the CBDT Circular of April 2017, which clarifies:
- Salary credited directly by employer to NRE account: Not taxable in India. The mere receipt of salary in an NRE account maintained with an Indian bank does not constitute income “received in India” under Section 5(2)(a).
- Salary credited to foreign account, then transferred to NRE account: Also not taxable. This is a transfer of funds between the seafarer’s own accounts, not receipt of income.
- Salary credited to NRO account: Technically may attract tax scrutiny as NRO is a resident account. However, the CBDT Circular provides that the salary is exempt even if credited to NRO. To avoid litigation, it is advisable to use the NRE account.
This circular is binding on the IT Department and provides significant protection. For seafarers using professional accounting services (https://www.patronaccounting.com/accounting-services) for ITR filing, ensuring that salary credits are routed through NRE accounts with proper documentation prevents unnecessary disputes.
Practical Examples: Day-Counting in Action
Example 1: Single Voyage, Indian Port to Foreign Port
Captain Sharma joins a container ship at Mumbai port on 5 April 2026 (CDC joining date). The ship sails to Rotterdam via the Suez Canal. He signs off at Rotterdam on 20 September 2026 (CDC signing-off date). He returns to India on 25 September 2026 (passport entry stamp).
Computation: CDC period excluded: 5 April to 20 September = 169 days. Remaining days in tax year (1 April 2026 to 31 March 2027): 365 - 169 = 196 days in India. Since 196 > 182, Captain Sharma is a resident unless he undertakes another eligible voyage that further reduces his India days below 182.
Example 2: Two Voyages, NRI Status Achieved
Officer Patil has two voyages in Tax Year 2026-27: Voyage 1: CDC join 10 April, CDC sign-off 25 August (138 days). Voyage 2: CDC join 15 November, CDC sign-off 10 February (88 days). Total CDC days excluded: 138 + 88 = 226 days. Remaining days in India: 365 - 226 = 139 days. Since 139 < 182, Officer Patil is Non-Resident. His ship salary is exempt from Indian tax.
Example 3: 120-Day Rule Triggered
Engineer Das stays in India for 150 days (after Rule 8 exclusion) and has rental income of Rs 18 lakh from Indian property. Since 150 days is between 120-181 and Indian income exceeds Rs 15 lakh, he becomes a Resident under Section 6(1A). However, since he was NRI in 8 out of the preceding 10 years and was in India for less than 730 days in the preceding 7 years, he qualifies as NOR (Not Ordinarily Resident). His ship salary remains non-taxable. Only his Indian rental income is taxable.
What Changed in the 2025 Act / Rules 2026?
| Aspect | Old Framework (IT Act 1961) | New Framework (IT Act 2025) |
|---|---|---|
| Governing section | Section 6(1) first proviso (for Indian citizens leaving India for employment) | Section 6(6) - specific provision for Indian citizen crew of foreign-bound ship |
| Governing rule | Rule 126 (inserted by Notification 70/2015) | Rule 8 of Draft IT Rules, 2026 |
| Wording | “For the purpose of employment outside India” | “For employment outside India” - tightened; requires formal employment documentation |
| Year concept | Financial Year (1 April to 31 March) + separate Assessment Year | Tax Year (1 April to 31 March) - FY and AY merged into single concept from April 2026 |
| 120-day rule | Section 6(1A) (inserted by Finance Act 2020) - 120 days + Rs 15 lakh = resident | Carried forward under the 2025 Act; ship income excluded from Rs 15 lakh computation |
| CDC definition | As per Merchant Shipping (CDC-cum-Seafarer’s Identity Document) Rules, 2001 | Same definition carried forward in Rule 8(3) |
| Eligible voyage | Voyage in international traffic: Indian port → foreign port or vice versa | Same definition carried forward in Rule 8(3) |
Critical change: The tightened wording “for employment outside India” means seafarers must maintain formal employment contracts with ship owners or management companies. Seafarers operating independently or without documented employment relationships may face challenges in establishing NRI status under the new Act. For companies registered through company registration (https://www.patronaccounting.com/private-limited-company-registration) that employ seafarers, issuing proper employment contracts with clear terms of overseas engagement is now essential for employee tax compliance.
Do Seafarers Need to File ITR?
Filing an ITR is mandatory for a seafarer if their total income (before deductions) exceeds the basic exemption limit:
- NRI seafarer with Indian income > Rs 2.5 lakh (old regime) or Rs 4 lakh (new regime): Must file ITR. Indian income includes: bank interest (savings, FD), rental income, capital gains on Indian assets, and any other Indian-source income.
- NRI seafarer with Indian income below the threshold: Not mandatory, but highly recommended. Filing ITR serves as proof of NRI status, supports loan and visa applications, creates a compliance record, and provides a defence against future IT Department inquiries.
- NRI seafarer with cash deposits > Rs 1 crore in current accounts, foreign travel expenditure > Rs 2 lakh, or electricity expenditure > Rs 1 lakh: Must file ITR regardless of income level.
Ship salary credited to NRE account is not included in total income for ITR purposes if the seafarer is NRI. However, it is advisable to disclose it in the ITR under the exempt income schedule for transparency.
Common Mistakes to Avoid
Mistake 1: Using passport dates when CDC dates should be used. For voyages starting or ending at Indian ports, Rule 8 mandates CDC dates. Using passport dates may undercount the days outside India and incorrectly classify the seafarer as a resident.
Mistake 2: Not computing days for each voyage separately. If a seafarer undertakes multiple voyages in a tax year, each voyage’s CDC period must be computed separately and then aggregated. Do not approximate or use a single continuous period.
Mistake 3: Including ship income in the Rs 15 lakh computation. The Rs 15 lakh threshold under Section 6(1A) applies to Indian taxable income. Ship salary of an NRI seafarer for services outside India is not included in this computation.
Mistake 4: Not maintaining CDC and passport records. The IT Department cross-verifies CDC dates with passport stamps during scrutiny. Discrepancies between the two can trigger disputes. Maintain clear records of both.
Mistake 5: Receiving salary in NRO instead of NRE account. While the CBDT Circular protects NRO salary receipts from taxation, using NRE accounts avoids unnecessary scrutiny and litigation. Always route ship salary through the NRE account.
Key Takeaways
Rule 8 of the Draft IT Rules, 2026 (replacing old Rule 126) provides a clear, CDC-based method for computing the period of stay in India for Indian citizens who are members of a foreign-bound ship’s crew. The entire period between the CDC joining date and CDC signing-off date for an eligible voyage (international traffic: Indian port to foreign port or vice versa) is excluded from the count of days in India.
A seafarer needs to spend less than 182 days in India (after Rule 8 exclusions) to qualify as a non-resident. Even if the 120-day/Rs 15 lakh rule triggers resident status, the NOR classification protects foreign ship salary from Indian taxation. Salary credited to NRE accounts is not taxable regardless.
The IT Act, 2025 tightens the wording to “for employment outside India,” requiring formal employment documentation. The Tax Year concept (effective April 2026) simplifies the year reference but does not change the 182-day computation methodology. For Indian seafarers, maintaining accurate CDC records, passport stamps, employment contracts, and NRE account documentation is the foundation of tax-efficient compliance.
