A self assessment tax return accountant helps individuals, sole traders, and landlords calculate their tax liability. They also help claim allowable expenses and submit accurate returns to HMRC before the 31 January deadline. Gowin Accountants Ltd is based in Basingstoke and provides fixed-fee Self Assessment services across the UK. The company offers same-day response times and has over 10 years of UK tax compliance experience.
Filing a tax return can feel like navigating a maze without a map. HMRC rules can change from year to year, while penalties for mistakes can be costly. Whether you’re a sole trader, landlord, or contractor, getting your figures right is essential. Meeting the deadline is equally important. This is where a dedicated self assessment tax return accountant can help. They provide peace of mind and can help you claim the expenses and allowances you’re entitled to.
At Gowin Accountants Ltd, we’ve spent over a decade helping individuals and businesses across Basingstoke and the wider UK. We help clients stay compliant with HMRC and keep more of what they earn. Our fixed-fee accountancy package includes bookkeeping and Self Assessment support. Every client also receives support from a dedicated accountant who understands their financial situation.
What does a self assessment tax return accountant actually do?
A self assessment tax return accountant manages the full process of calculating and submitting your annual tax return to HMRC. This typically covers:
- Reviewing income from employment, self-employment, property, dividends, and other sources
- Identifying allowable expenses and reliefs you’re entitled to claim
- Calculating your total tax liability, including any Class 2 or Class 4 National Insurance contributions
- Preparing and submitting your return before the 31 January online filing deadline
- Liaising directly with HMRC on your behalf if queries or penalties arise
For sole traders, landlords, and contractors, this support removes much of the guesswork from a process that HMRC itself acknowledges causes confusion for many taxpayers each year.
Who actually needs to file a Self Assessment tax return?
You’re generally required to register for Self Assessment and file a return if you:
- Are self-employed as a sole trader and earned more than £1,000
- Are a partner in a business partnership
- Earn rental income from property, including buy-to-let
- Receive untaxed income, such as dividends or savings interest above your allowance
- Earn over £100,000 through PAYE employment
- Claim certain reliefs, such as high-income child benefit charge repayments
If any of these apply to you, working with a self assessment tax return accountant early in the tax year, rather than in the panicked weeks before January, gives you far more room to plan and reduce your bill legitimately.
Why does filing accuracy matter so much for tax compliance?
HMRC applies penalties for late filing, late payment, and inaccurate returns, and these can escalate quickly. An initial £100 fine for missing the deadline can grow into daily penalties, interest charges, and further fines for continued delays. Errors caused by miscalculated expenses or omitted income can also trigger HMRC enquiries, which are time-consuming and stressful to resolve alone.
A qualified self assessment tax return accountant reduces this risk by:
- Cross-checking figures against bank statements, invoices, and receipts
- Ensuring allowable expenses are claimed correctly, without over- or under-claiming
- Flagging any inconsistencies before submission, not after HMRC raises a query
- Keeping records organised in case of a future compliance check
At Gowin Accountants Ltd, we support clients using Xero cloud accounting software, included at no extra cost, so your income and expenses are tracked in real time rather than reconstructed from memory each January.

One recent client contacted our team on a Monday for help with an overdue Self Assessment return. Our accountants resolved the issue and completed the submission by Tuesday evening, demonstrating the kind of responsiveness that matters when deadlines are tight.
When should you contact a self assessment tax return accountant?
Choose to bring in support early in the tax year if you want time to plan tax-efficient decisions, such as pension contributions or timing of income. Choose to contact an accountant urgently if you’re approaching the January deadline, have received an HMRC penalty notice, or are unsure whether you need to register for Self Assessment at all. In both cases, Gowin Accountants Ltd offers a free consultation to assess your situation before any commitment is made.
Frequently asked questions
How much does a self assessment tax return accountant cost?
Costs vary depending on the complexity of your income sources, but Gowin Accountants Ltd offers a fixed-fee package with no hidden charges, so you know your costs upfront rather than being billed hourly.
What is the deadline for filing a Self Assessment tax return?
The online filing deadline is 31 January following the end of the tax year on 5 April. Paper returns must be submitted by 31 October.
What happens if I file my tax return late?
HMRC issues an initial £100 penalty for missing the deadline, with further daily charges and interest applying the longer the return remains outstanding.
Can an accountant help if I’ve already received an HMRC penalty?
Yes. Gowin Accountants Ltd regularly supports clients who are dealing with existing penalties, helping resolve issues with HMRC and get future filings back on track.
Do I need an accountant if my tax affairs are simple?
Not necessarily, but even straightforward returns benefit from a professional check to ensure allowable expenses and reliefs aren’t missed, which often outweighs the cost of the service itself.
