NavikTax
Days in India, counted.
182 days in India and your sea pay can be taxed. NavikTax counts your days, warns you in time, and keeps the proof. Free, and we never see your data.
An NRI days calculator made for seafarers.
Spend 182 days or more in India in a tax year and your pay for work at sea can be taxed in India. Most seafarers count on paper, or do not count at all, and find out too late. NavikTax counts the days for you, warns you in time, and gives you a PDF of your trips and days as proof for your income tax return.
Plan.
On a ship and wondering when you can sign off? Plan ahead gives you the last safe day to sign off. At home, it tells you the day to sign on by.
Prove.
One tap makes a 3-page PDF statement: your details, every trip with both sets of dates, the days this year and in the 4 years before, and photos of your CDC pages and passport stamps.
Questions people ask
- How does the 182-day rule work for seafarers?
- India's income tax law treats you as a resident for a tax year if you are in India for 182 days or more in it. For a seafarer, the days outside India on a voyage between an Indian port and a foreign port run from the CDC sign-on date to the CDC sign-off date, both included. For a voyage between two foreign ports, the days between your passport stamps count. The app's Rules tab explains each case with its source.
- Why does the app show two counts?
- The day you land in India is disputed: tax officers count it, several tribunals leave it out. NavikTax plans by the strict count and shows the kinder one beside it, so you are never caught out.
- Which tax year does it count?
- India's, 1 April to 31 March. The dial shows the current year, and the PDF also lists your days in the 4 years before, because some rules look back that far.
- What about income in India, NRE accounts and the Rs 15 lakh rule?
- Seven short rules pages in the app cover them in plain words: the 182-day rule, which dates count, the day you arrive, what happens if you cross the limit, income in India above Rs 15 lakh, NRI bank accounts, and salary paid into an NRE account. Each names its source in the Income-tax Act 2025 and the Income-tax Rules 2026.
- Does it work at sea, without internet?
- Yes. Everything is counted and stored on your phone. Nothing needs a connection.
- Will the tax office accept the PDF?
- The PDF states your days from your own documents, in the words of the return, and says what it is. Nothing is attached to a return in India; you keep the statement ready in case you are asked.
- Is NavikTax a government app, or tax advice?
- Neither. NavikTax is made by Waypoints Labs, a company in Singapore. It states days, never a legal conclusion, and the PDF says so on every page. For advice on your own return, ask a chartered accountant.
- Where is my data?
- On your phone, and in your own iCloud backup. NavikTax has no account, no ads and no server. Your trips, your details and your photos never reach us. A backup file you can export moves everything to a new phone. Read the NavikTax section of our privacy policy.
- Where do I get help?
- The NavikTax support page covers moving to a new phone, Hindi, and what to do if you cross the limit. For anything else, write to hello@waypoints.sg. Please do not send your PAN or passport number.
