Interbank Offered Rate Reform & the Tax Implications

IRAS explains how benchmark-rate changes interact with accounting relief and the existing tax character of financial instruments.

Source checked · 11 October 2026

Key requirements

The page was written around the transition from SOR and SIBOR to SORA, citing 2023 and 2024 discontinuation dates. Where the IASB practical relief is adopted, tax generally follows the relevant accounting treatment within the existing FRS 109 rules. Revenue-account interest and trading swaps differ from capital-account borrowing and hedging. If contracts are rescinded and replaced, the change may constitute refinancing: an unchanged or lower principal generally retains its prior character, while additional borrowing is tested by its own use. Keep amendments, principal reconciliations and the use of extra funds. Historical transition dates on this source should not be read as future events as of October 2026.
