What is a Self-Assessment Tax Return?
A Self-Assessment Tax Return is how individuals report their income to HMRC when it’s not automatically taxed. If you’re self-employed, receive rental income, dividends, or foreign earnings, you must declare this via a SA100 tax return form. Understanding who needs to do a tax return is the first step, and we can clarify the requirements for you.
Common Challenges Self-Employed Personals Face
- I don’t know what expenses I can claim
- I missed the deadline or filed late before
- I don’t have time to deal with HMRC forms
- I’ve just gone self-employed and need help
- I’m not sure if I even need to complete a tax return
- I’m afraid of making mistakes and getting fined
- I have multiple income sources (e.g., freelance + rental)
The Risks of Filing Incorrectly or Late
If you file your tax return late or with mistakes, it can cause more trouble than you might expect. HMRC will fine you £100 right away if you miss the deadline. Then, after three months, the fines start adding up every day. You’ll also owe interest on any tax you haven’t paid yet. If you keep making errors, HMRC might even open an investigation, which is stressful and takes time.
It’s easy to make honest mistakes. Maybe you forgot to include some income or claimed something that isn’t allowed. Even small errors like these can lead to checks that mess with your money and peace of mind.
Penalty Triggers You Can Avoid With Lanop
- Submitted incomplete records
- Missed out on allowable deductions
- Missed the 31 January filing deadline
- Claimed ineligible expenses or reliefs
- Incorrect calculation of taxable income
- Filed without registering for self-assessment
