Self Assessment is the system HMRC uses to collect tax from people whose income isn't taxed automatically through an employer. If you're self-employed, a company director, earn over £100,000, have rental income, or receive untaxed income of any kind — there's a good chance you need to file.
Who needs to file?
- Self-employed individuals earning over £1,000
- Company directors
- People with income over £100,000
- Landlords with rental income
- Anyone with untaxed income — investments, tips, foreign income
- CIS subcontractors in construction
Missing the 31 January deadline means an automatic £100 fine — even if you owe nothing. Late returns that go beyond 3 months can attract daily penalties of £10, up to £900.
Why most people pay too much
Self Assessment returns look simple on the surface. But the allowable deductions — home office, mileage, equipment, phone, pension, professional fees — are easy to miss if you don't know what to look for. HMRC won't remind you to claim them.
A professional accountant identifies deductions you wouldn't think of yourself. In most cases, the tax saved far exceeds the cost of the service.
