Hi
Article 20 of the UK / India tax treaty (
2020 UK-India Synthesised text of the Multilateral Instrument and the 1993 Double Taxation Convention — in force Updated 12 October 2022) confirms that pensions paid to a resident of the UK, are taxable in the UK. Article 21 relates to students, but does not cover pension payments. If you choose to claim the remittance basis, you will be required to complete a self assessment tax return to claim the remittance basis and declare the unremitted income. The guidance at
Tax on foreign income, advises that up to £15000 if this income can be set against food, rent, bills and study materials. Any unremitted income used on things other than living costs and course fees, is taxable in the UK and would need to be declared on the self assessment tax return. Using an overseas bank or credit card to purchase items other than living costs and course fees, is remitted income and is taxable.
