Improved Self Assessment registration service launched.
HMRC has launched an improved online service to help individuals register for Self Assessment. Anyone who needs to file a tax return for the first time for the 2025 to 2026 tax year must register by 5 October 2026 to avoid a potential penalty. Customers can use the online checking tool on GOV.UK to determine if they are required to register.
