The UK tax rule on FCNR deposits is weakening their appeal among some wealthy NRIs because overseas interest may be taxed in Britain. Higher Indian returns and the RBI-backed incentive remain attractive, but investors must now compare headline rates with their final post-tax income.

UK tax rules are weakening the appeal of Foreign Currency Non-Resident, or FCNR, deposits for some wealthy NRIs, particularly long-term UK residents who may owe British tax on interest earned through accounts held in India.

FCNR deposits remain tax-exempt in India for eligible non-residents. However, that Indian exemption does not automatically prevent the interest from being taxed in the account holder’s country of residence.

UK worldwide income rules change the calculation

The United Kingdom abolished its previous remittance-basis system on April 6, 2025, replacing it with a residence-based framework. UK residents are normally taxed on foreign income unless they qualify for specific relief.

This means interest earned from an FCNR deposit may form part of a UK resident’s taxable overseas income, even when the money remains outside Britain.

The impact is not identical for every NRI. Qualifying new residents may claim relief under the four-year Foreign Income and Gains regime after spending at least 10 consecutive tax years outside the UK.

FCNR deposits still offer currency protection

FCNR accounts allow eligible NRIs to place fixed deposits in designated foreign currencies, including U.S. dollars, British pounds and euros. Because the deposit and repayment remain in the same foreign currency, investors avoid direct exposure to rupee depreciation.

The interest is generally tax-free in India for eligible account holders, and the principal and interest can be repatriated.

However, investors subject to UK tax must evaluate the return after British tax rather than relying only on the advertised deposit rate.

RBI incentive supports higher FCNR returns

India introduced a time-limited incentive aimed at attracting additional foreign-currency inflows. Under the arrangement, hedging costs are covered for qualifying new FCNR(B) deposits with maturities of three to five years booked by September 30, 2026.

The incentive has allowed participating banks to offer more competitive rates, with some offers reported above 7%. Actual rates, eligibility requirements and early-withdrawal terms vary by bank.

Wealthy UK-based NRIs may reassess returns

The tax change is particularly relevant to high-net-worth NRIs using large or leveraged deposits. UK tax on interest, borrowing expenses and restrictions on deductible costs can materially reduce the final return.

Banks may therefore receive weaker demand from affluent UK residents even while FCNR products remain attractive to investors living in countries with different tax treatment. Reports indicate that FCNR inflows have already begun slowing as wealthy depositors examine taxation and financing costs.

UK-based NRIs considering an FCNR deposit should review their residence status, eligibility for foreign-income relief, applicable tax rate and the deposit’s withdrawal conditions. The investment may still provide currency stability and competitive income, but its value now depends more heavily on the investor’s individual post-tax return.
