Who needs to complete a Self Assessment tax return?
Not everyone pays tax through Self Assessment, but you may need to submit a tax return if you receive income that is not fully taxed at source or have certain financial circumstances.
This can include:
-
Self-employed individuals: If you run your own business or work for yourself, you may need to report your business income and expenses
-
Company directors: You may need to complete a personal tax return depending on your income and circumstances.
-
Landlords: If you receive rental income from property, you may need to declare it to HMRC
-
People with additional income: This could include dividends, savings interest, investment income or income from other sources
-
Individuals with capital gains: You may need to report certain profits from selling assets, property or investments
-
Higher earners: Some people need to complete a tax return because of their income level or other tax-related circumstances
If you are unsure whether you need to complete a tax return, we can help you establish what applies to you.
Avoid missing deadlines and making mistakes
Self Assessment deadlines are important. Missing a submission or payment deadline can result in penalties and interest from HMRC.
Even if you have completed tax returns before, changes in your income, work or personal circumstances can make things more complicated.
Using an accountant can help you avoid common errors, understand what information you need to provide and make sure your return is dealt with correctly.
We can also help you understand your tax bill in advance, so you have time to prepare for the payment rather than being caught out.

FAQs
Do I need an accountant to complete my Self Assessment tax return?
No, you can complete and submit your own tax return. However, an accountant can help you understand what needs to be declared, identify relevant expenses and allowances and make sure your return is prepared correctly.
When is the Self Assessment tax return deadline?
For online tax returns, the usual deadline is 31 January following the end of the tax year. Paper returns generally have an earlier deadline of 31 October. There are also payment deadlines to consider, so it is important to leave enough time to prepare your return.
Can you complete a Self Assessment tax return for someone who is self-employed?
Yes. We can help self-employed individuals report their business income and allowable expenses, prepare their tax return and submit it to HMRC.
Can you help landlords with their tax returns?
Yes. We can help landlords report rental income and relevant expenses as part of their Self Assessment tax return, taking account of their individual circumstances.
What information do I need to provide for my tax return?
This will depend on your circumstances, but may include details of your income, business expenses, rental income, dividends, savings interest, pension contributions and any other relevant financial information. We can explain what is needed for your return.
Can you submit my Self Assessment tax return to HMRC?
Yes. Once we have the information needed and you have reviewed and approved the return, we can submit it to HMRC on your behalf.
What happens if I miss the Self Assessment deadline?
HMRC can charge an initial late filing penalty, followed by further penalties if the return remains outstanding. Interest and late payment penalties may also apply if you do not pay your tax on time. If you think you may miss a deadline, it is important to seek advice as soon as possible.
Can you help me understand how much tax I owe?
Yes. Once your tax position has been established, we can explain the amount due, when it needs to be paid and whether payments on account may apply.
