Global Daily Tax News, UK Urged To Consider January Tax Year Start, (Feb 3, 2025)

The Chartered Institute of Taxation in the UK has called on the Government to consider aligning the tax year with the calendar year.

The organization said the change would support efforts to simplify the taxation of interest earned overseas.

In the CIOT's response to an ongoing government consultation on the subject, the Institute suggested the changes proposed by the Government to the taxation of interest earned overseas should apply to all overseas investment income reported under automatic exchange of information agreements – not just interest.

On the specific proposal to change the assessment period for offshore interest, the CIOT has proposed several recommendations to improve the process for both taxpayers and HMRC including:

• Keeping the technical details simple to avoid creating a complex system with numerous exceptions and transitional rules;

• Emphasizing the importance of clear communication and guidance to ensure taxpayers understand any changes to the assessment period and their reporting obligations; and

• Striking the right balance between flexibility and simplicity in reporting requirements.

Margaret Curran, CIOT Technical Officer for the Management of Taxes Committee, said: "We welcome HMRC's focus on simplifying the taxation of offshore interest, which can be a source of confusion for many taxpayers, as well as creating problems for HMRC's compliance activity. Aligning the assessment period for offshore interest to the calendar year could mitigate issues caused by mismatches between the UK tax year and the calendar year reporting used by many countries."

"However, we believe an even better solution would be to align the UK tax year to the calendar year. This would bring many benefits including better understanding by taxpayers and greater alignment with other countries, although we recognize that the transitional period would require careful management."
