Find Self Assessment Accountants in the UK
Self Assessment is the system HMRC uses to collect Income Tax that has not been fully dealt with through PAYE or another deduction method. Filing requirements depend on income sources and circumstances, so use HMRC's current checker rather than assuming that a job title or income level alone creates an obligation.

Self Assessment FAQs
Who needs to file a Self Assessment tax return?
Common reasons include self-employment, partnership income, untaxed property or investment income, and chargeable gains. Being a company director does not by itself always require a return. Use HMRC's current online checker because the tests and reporting thresholds can change.
When is the Self Assessment deadline?
The deadline for online Self Assessment tax returns is midnight on 31 January following the end of the tax year. For paper returns, the deadline is 31 October. The tax year runs from 6 April to 5 April the following year.
How much does a Self Assessment accountant cost?
Fees depend on the number of income sources, record quality, capital gains, property or foreign income, and how close the filing deadline is. Ask for a written fixed-fee scope that says what records, calculations, advice, and HMRC submission work are included.
