Seafarer taxation is one of the most misunderstood areas of NRI tax, and a lot of what’s written about it online is outdated — written before the Income Tax Act, 2025 and before some of the day-counting rules were reorganised. Here’s what actually applies right now, with the specific carve-out most guides skip.
Seafarer Isn’t a Defined Tax Term — Your Residential Status Is What Matters
Neither the old Income Tax Act, 1961 nor the Income Tax Act, 2025 defines “seafarer” or “merchant navy” as a legal category. There is no special exemption schedule for seafarers as a class. What determines your tax liability is purely your residential status for the year — resident, RNOR, or non-resident — computed the same way it is for any Indian citizen, but with one crew-specific day-counting mechanism that changes the arithmetic significantly in your favour.
The CDC Day-Count Rule — Why Days at Sea Don’t Count as Days in India
Under the new Act (Section 6(6), with the computation method in Rule 8 of the Income Tax Rules, 2026 — replacing the old Rule 126), if you’re an Indian citizen crewing a foreign-bound ship on an “eligible voyage” (one where either the origin or destination port is in India), the entire period between your Continuous Discharge Certificate (CDC) joining date and sign-off date is excluded from your “period of stay in India” — even if the ship passes through Indian territorial or coastal waters during that voyage. This is the single most valuable rule in seafarer taxation and the one most likely to be miscounted if you go by passport stamps alone instead of your CDC.
Does the 120-Day “Deemed Resident” Rule Apply to You? No.
A lot of seafarer tax content online still flags the 120-day rule (where an Indian citizen with India income above ₹15 lakh becomes a “deemed resident” by spending just 120+ days in India, instead of the usual 182) as something to watch for. It doesn’t apply to seafarers. This is an explicit statutory carve-out — seafarers continue to use the standard 182-day threshold regardless of income level. If a guide you’re reading presents the 120-day rule as a live risk for you without mentioning this exclusion, that guide is incomplete.
Is Your NRE Salary Actually Tax-Free?
Yes, with the right documentation. Per CBDT Circular No. 13/2017, salary paid to a non-resident seafarer for services rendered outside India on a foreign ship is not taxable in India merely because it was credited to an NRE account held with an Indian bank. The exemption follows from your non-resident status and where the service was rendered — the NRE account is just where the money lands, not what makes it exempt. Keep your CDC, employment contract, and salary certificate together; this is exactly the documentation set that gets checked if your return is ever queried.
Which ITR Form, and What We Charge
Seafarers with exempt foreign salary plus any India-source income (NRO interest, rent, capital gains) file ITR-2, disclosing the exempt salary and, where applicable, Schedule FA for foreign assets. If you have business income from a proprietary source, ITR-3 applies instead. Our fee for ITR-2 filing starts at ₹3,499, reviewed personally by a Fellow Chartered Accountant — no hidden charges, no quote-on-request. If your residential status is borderline for the year (a short voyage, a delayed sign-off, time split across foreign and domestic-flag ships), we’ll work through your CDC dates with you before filing, not after.
Send your CDC and voyage dates to hello@nritaxca.com or via WhatsApp and we’ll tell you plainly where your residential status stands before you file anything.
