Self-Assessment Tax Return
Self-Employed Accounting
Who needs to file a Self-Assessment?
You must complete a self-assessment tax return if you earn income in the UK other than a salary or pension. This includes income from:
- self-employment
- property rental
- selling on Etsy, eBay and similar platforms (over £1,000 per year)
- savings, investments or dividends
- overseas income
- selling assets, e.g. property or shares
- partnership income (e.g. being a partner in a limited company)
- construction subcontracting under the CIS
If you are a UK landlord living in Poland, you are also required to submit a self-assessment for your rental income.
Employees with Additional Income Outside of Employment
If you are employed and receive a P60, your employer only reports your income from that employment. However, if you also have other sources of income – such as dividends, rental income, or cryptocurrency sales – you must report them yourself through a Self-Assessment tax return.
