The India-Singapore Double Taxation Avoidance Agreement, in force since 1994 and amended by a 2016 Protocol effective 1 April 2017, prevents Indian-source and Singapore-source income from being taxed twice for NRIs who qualify as tax resident in both countries, while Singapore itself taxes individuals mainly on Singapore-sourced income, with no capital gains tax and a top individual rate of 24% on chargeable income above S$1,000,000.
The India-Singapore DTAA and the 2017 capital gains shift
The India-Singapore Double Taxation Avoidance Agreement has been in force since 1994, and was substantially
amended by a Third Protocol (signed 30 December 2016, effective 1 April 2017) that restructured how capital
gains on shares are taxed. Shares acquired before 1 April 2017 remain grandfathered -- taxable only in the
seller's country of residence. Shares acquired between 1 April 2017 and 31 March 2019 fall into a transitional
category, taxed in India at a reduced rate subject to a Limitation of Benefits condition requiring genuine
operating substance in Singapore. Shares acquired from 1 April 2019 onward are fully taxed in India at standard
domestic rates, with no treaty concession -- this change was made in step with an equivalent amendment to the
India-Mauritius DTAA, specifically to close the pre-2017 practice of routing Indian equity investments through
Singapore or Mauritius shell entities purely to avoid capital gains tax. The exact current Limitation of
Benefits thresholds should be checked against the Protocol text or current CBDT guidance rather than assumed
from memory.
Singapore's individual tax system
Singapore taxes individuals primarily on Singapore-sourced income; foreign-sourced personal income is
generally outside the scope of Singapore individual taxation altogether (a narrow exception applies to certain
foreign income received through a Singapore partnership), which is a simpler and broader exemption than a
remittance-basis system. There is no capital gains tax in Singapore. Resident individuals are taxed on a
progressive scale starting at 0% on the first S$20,000 of chargeable income, rising through several bands, with
a top marginal rate of 24% applying to chargeable income above S$1,000,000 -- a structure in place since Year of
Assessment 2024 and current through 2026. The full official bracket table should be checked on IRAS's website
for exact current figures at each band.
Avoiding double taxation as a dual tax resident
An NRI who ends up tax resident under domestic law in both India and Singapore in the same year relies on
the DTAA's tie-breaker rules (typically based on permanent home, centre of vital interests, and habitual abode)
to determine which country has primary taxing rights, and on the treaty's relief provisions -- generally the
credit method, where each country allows a credit for tax already paid in the other on the same income -- to
avoid being taxed twice. A common practical scenario is Singapore employment income combined with India-source
income such as rental income or NRE/NRO deposit interest, where the DTAA read together with India's domestic
NRI tax rules determines the final tax outcome.
If I sell shares in an Indian company while living in Singapore, do I pay capital gains tax in India?
It depends on when the shares were acquired -- shares bought before 1 April 2017 are generally grandfathered
and taxed only in your country of residence, shares bought between 1 April 2017 and 31 March 2019 fall into a
transitional reduced-rate category, and shares bought from 1 April 2019 onward are fully taxed in India at
standard domestic rates under the current DTAA framework.
Does Singapore tax my Indian rental income or NRE deposit interest?
Generally no -- Singapore taxes individuals mainly on Singapore-sourced income, and foreign-sourced personal
income like Indian rental income is generally outside the scope of Singapore individual taxation altogether,
though your Indian-side tax obligations on that same income are a separate question governed by Indian law.
Is there capital gains tax on my Singapore investments?
No -- Singapore does not levy capital gains tax on individuals, which is one of the reasons Singapore is a
popular base for NRIs' investment holdings, though gains connected to Indian assets remain subject to Indian
capital gains rules as described above.
