UK, December 13, 2024- Self-Assessment is the system used by HMRC to collect income tax from individuals who are self-employed or have untaxed income. It’s crucial to file accurately and on time to avoid penalties and maximize legal tax savings. Below, we discuss the top 15 common mistakes made during the Self-Assessment process and provide tips on how to avoid them.
1. Forgetting to Register for a Government Gateway Account

- Mistake:Not registering early enough or misplacing login details.
- Impact:Delays in filing and potential penalties.
- Prevention:Register early and keep your login information secure.
