Do I need an accountant for Self Assessment?
You do not legally need an accountant for Self Assessment, but one can be useful if you have self-employment, rental income, capital gains, foreign income, dividends, high income, or incomplete records.

When DIY may be enough
A simple return with one income source and clear records may be manageable yourself, especially if you understand what HMRC is asking for and have time to check the figures.
When advice is worth comparing
Accountant support is more valuable when the return includes property, sole trader profits, capital gains, foreign income, crypto, dividends, high income child benefit charge, student loans, or payments on account.
