Personal tax and Self Assessment support in Oxford
M A Accounting helps employees, directors, contractors and landlords in Oxford and across the United Kingdom to file accurate Self Assessment tax returns on time and avoid penalties, interest and HMRC stress.
What is Self Assessment and when are the deadlines
Understanding the rules so you avoid penaltiesSelf Assessment is the system that HM Revenue and Customs uses to collect Income Tax where it is not fully collected through PAYE. If you have additional income such as rental profits, self-employed income, dividends or capital gains, you may be required to submit a tax return even if most of your income is taxed at source.
Personal tax year dates
The United Kingdom personal tax year runs from 6 April to 5 April. Your Self Assessment return covers everything that happened in that period, including employment income, rental profits, bank interest, dividends and any capital gains.
Key filing and payment dates
Paper returns usually need to reach HMRC by 31 October following the end of the tax year. Online returns must be filed by 31 January following the end of the tax year and the balancing tax payment is due on the same date unless HMRC has agreed a time to pay arrangement.
Late filing and late payment
There is an automatic fixed penalty if your tax return is late, even when no tax is due. Further penalties and interest apply if your return or payment remains outstanding. Completing your return correctly and early gives more time to budget and reduces the risk of unnecessary fines.
You can usually submit your online tax return soon after the tax year ends. Early filing means you know your bill well before 31 January and can set up payments or a time to pay plan if needed. It also reduces the risk of missing the deadline because of system issues, bank delays or illness.
You can use the free Self Assessment checker and online tax account on the government website to see whether you need a return and to view payments and statements. Our UK income tax calculator can also help you estimate potential liabilities before the return is filed. We can guide you through registration, login and setting up secure access.
Who typically needs to complete a Self Assessment tax return
Common examples for Oxford clientsHMRC sets out detailed rules on who must send a tax return. In practice, many of our personal tax clients fall into one or more of the categories below. If you are unsure whether you should be filing, we can review your situation and confirm the position before penalties arise.
- You are self employed or a sole trader and your trading income is more than the current allowance for small trading activity.
- You are a partner in a business partnership, even if the partnership itself is small.
- You are a company director and receive dividends or other income that is not fully taxed through payroll.
- You receive rental income from a property or room whether in Oxford, elsewhere in the United Kingdom or overseas.
- You have significant savings interest, dividends or investment income above the tax free allowances.
- You realised capital gains on shares, crypto assets or property beyond your annual exemption.
- Your income is high enough to trigger the High Income Child Benefit Charge.
- HMRC has issued a notice to file a return, even if you think your income is straightforward.

Personal tax and Self Assessment frequently asked questions
Practical answers for Oxford clientsDo I need to use an accountant for my Self Assessment tax return
There is no legal requirement to use an accountant. Many people choose to do so because their affairs are not straightforward or they do not have time to keep up with changing rules. An accountant can help you avoid common errors, claim relevant allowances and deal with HMRC on your behalf.
Can you still help if I live outside Oxford
Yes. While we are based in Oxford and understand local employers and property markets well, we act for personal tax clients throughout the United Kingdom. Information is collected securely online and meetings can be held by phone or video.
What happens if I have missed the Self Assessment deadline
If you miss a filing or payment deadline, HMRC will normally charge fixed penalties and interest, with further penalties as the delay increases. It is still better to file as soon as possible rather than wait. We can prepare the overdue return, review penalty notices and advise whether a reasonable excuse appeal may be appropriate.
How long should I keep my records for
As a general rule, HMRC expects individuals who complete a Self Assessment return to keep records for at least one year after the normal filing deadline, and often longer if you are self employed or have rental income. In practice, we recommend keeping key documents for several years so that any queries can be answered easily.
Can you help with both my company accounts and my personal tax
Yes. At M A Accounting we act for many limited company directors where we look after the company accounts, corporation tax and payroll alongside personal dividends, rental income and Self Assessment. This joined up approach helps to manage profit extraction, cash flow and tax planning across your company and personal position.
