Bogotá taxes your Indian interest. India should take less.

Colombia's credit stops at Colombian tax. Article 254 of the Tax Statute caps the credit for foreign tax at the Colombian tax on the same income. Colombia's rates start at 0% on the first 1,090 UVT (tax units) of taxable income. If your bank deducts 30% because it has no TRC and Form 41, Colombia will not credit the part above its own tax on that income. Use the 10% treaty rate at the bank. Anything deducted above it comes back only through an Indian income tax return.

The 5% dividend cap is easy to miss. Article 10 caps India's tax on dividends at 5% for any Colombia resident, but Indian companies and fund houses deduct 20% from non-residents unless they hold your TRC and Form 41. Send both to each company registrar or your broker before the record date.

Colombia gives no underlying-tax credit on portfolio dividends. The treaty (Article 23(2)) offers a credit for Indian corporate tax behind a dividend, but only within Colombian law. Tax Statute Article 254 limits that indirect credit to holdings that are fixed assets, not portfolio investments. A portfolio investor gets credit only for the Indian tax deducted from the dividend itself.

Indian assets need a separate Colombian declaration. Under Tax Statute Article 607, a resident whose foreign assets exceed 2,000 UVT on 1 January must file an annual foreign assets declaration. Assets above 3,580 UVT are listed one by one, with the country where they sit. Your NRO and NRE deposits, Indian funds and any flat in India all count.

Mutual funds and shares are treated in opposite ways in India. Indian mutual fund and ETF unit gains fall under Article 13(6), so India cannot tax them for a Colombia resident. Listed Indian shares fall under Article 13(5) and stay taxed in India at 12.5%. Colombia taxes the fund gain instead. Ask a CA to confirm the fund position before you claim it, and check that your fund house applies it.

Check residence before you rely on a TRC. You become resident by staying in Colombia more than 183 calendar days, counting entry and exit days, in any 365-day period. If that stay runs across two calendar years, you are resident from the second year. A recent arrival may not qualify for a certificate for the first year.

NRE interest is tax-free in India but taxable in Colombia. Colombia taxes residents on worldwide income, so NRE interest belongs on your Colombian return. India levies no tax on it, so there is no Indian tax to credit.

Capital income can also owe social contributions, which Indian tax does not offset. Colombia's pension and payroll contributions agency (UGPP) says people living on capital income such as interest, dividends and rent must contribute once their net monthly income reaches one minimum wage: 12.5% for health and 16% for pension, generally on 40% of net income, with a floor of one and a cap of 25 minimum wages. Pensioners and some older people who never joined a pension scheme are exempt from the pension part. UGPP does not say how it treats foreign interest, so ask a Colombian adviser whether your Indian NRO interest counts. There is no India-Colombia social security agreement (it is not on MEA's list) to change this.
