Simplifying Your Personal Tax Returns
Self Assessment is a system employed by HM Revenue and Customs (HMRC) in the UK to collect income tax from individuals and businesses. It is a way for taxpayers to report their income, gains, and other financial details, enabling HMRC to calculate the correct amount of tax owed.
With the personal allowance frozen until 2027-28, it is important to understand how this affects you and whether you now fall into Self Assessment. The personal allowance is the amount of income you can earn before you start paying income tax. This freeze means that as your income rises with inflation, you might find yourself exceeding the personal allowance threshold and therefore having an income tax liability.
Self Assessment Accountant Services You Can Rely On
Filing a Self Assessment tax return is one of those jobs most people would happily put off. The form asks questions you’re not always sure how to answer, the rules seem to change every year, and the 31 January deadline has a habit of arriving faster than expected. If that sounds familiar, you’re far from alone. More than 12 million people file a return each year, and a good self assessment accountant makes the whole thing far less stressful.
That’s where we come in. Bevan Buckland is Wales’ largest independent chartered accountancy firm, and we’ve supported individuals and businesses for over 125 years. Our team prepares your self assessment tax return, checks every figure, and submits it to HMRC on time, so you don’t have to think about it.
You get genuine peace of mind. You often get a smaller bill too, because we know which reliefs and allowances apply to your circumstances and where people tend to overpay. Here’s exactly what that looks like in practice.
What Our Self Assessment Service Includes
When you hand your return to us, you’re not just paying someone to type numbers into a form. You’re getting a qualified accountant for self assessment who reviews your whole position and looks for ways to make it work better for you.
We prepare and file your full return
We handle the return from start to finish. That means gathering your income and expense details, completing the right supplementary pages for your situation, calculating what you owe, and submitting everything to HMRC through the proper channels. You approve the final figures before anything is sent, so you’re always in control.
We find the reliefs and allowances you’re entitled to
This is where a self assessment tax return accountant usually earns their fee several times over. We check whether you can claim expenses, pension relief, Gift Aid, the Marriage Allowance, mortgage interest relief for landlords, and any other allowances that fit your circumstances. Get this right and your bill can drop noticeably. Get it wrong and you either overpay or invite questions from HMRC.
We deal with HMRC on your behalf
We act as your registered agent, which means we can talk to HMRC directly about your return. If a query comes back, we handle it. If you’ve had a letter that’s left you worried, we can step in and respond properly. Being a named agent also means correspondence about your Self Assessment comes to us, so nothing slips through the cracks.
We keep you ahead of every deadline
The main Self Assessment deadline is 31 January for online returns, with paper returns due by 31 October. You can see the current dates on the GOV.UK Self Assessment deadlines page. Miss it and HMRC issues an automatic £100 penalty, even if you owe no tax, with further charges building the longer it’s left. We track your deadlines, chase the information we need in good time, and make sure your return and any payments on account are dealt with before the clock runs down.
We explain everything in plain English
Tax is genuinely complicated, and we won’t pretend otherwise. What we will do is explain what’s happening in language that makes sense, so you understand your position rather than just handing it over and hoping for the best. If a technical term matters, we’ll tell you what it means and why it applies to you.

Your fee is agreed upfront, with no charge for queries
We agree an annual fee at the start, and it covers your day-to-day phone calls and emails at no extra cost. You’ll never hold back from asking a question because you’re worried about the bill. Additional fees will include anything outside the agreed scope of work.

Step 2: We will prepare your return. You send us your details, we will do the work and check the figures, then present them to you clearly.

Pricing
Everyone wants to know the same thing first: how much does a self assessment accountant cost? The honest answer is that it depends on how complex your return is. A straightforward return with a single income source costs less than one covering rental property, capital gains, and foreign income. What we can promise is a fixed fee agreed before we start, with no hidden costs and no surprises when the work is done. You’ll know the price upfront, and it’ll cover your questions throughout the year, not just the filing itself.
Frequently Asked Questions
Legally, no. You can file your own return through HMRC’s online service, and if your affairs are simple, that may be all you need. The value of an accountant for self assessment shows up when things get more involved, or when you’d rather not spend an evening wrestling with the forms. A good accountant makes sure your return is accurate, claims the reliefs you’re entitled to, and keeps you clear of penalties. For many people the tax saved and the time reclaimed more than covers the fee.
The cost of an accountant for self assessment depends on the complexity of your return. A simple return with one income source sits at the lower end, while returns involving rental income, capital gains, or overseas earnings take more work and cost more. At Bevan Buckland we agree a fixed fee before we start, so you know the self-assessment tax return accountant cost upfront with no surprises. Get in touch for a personalised quote based on your circumstances.
For online returns, the deadline is 31 January following the end of the tax year, which runs to 5 April. Paper returns are due earlier, by 31 October. Any tax you owe is also due by 31 January, and if you make payments on account, the second one falls on 31 July. We keep track of these dates for you and chase the information we need in good time.
HMRC issues an automatic £100 penalty the day after the deadline, even if you owe no tax or are due a refund. After three months, daily penalties of £10 can apply, up to a maximum of £900. At six and twelve months, further charges kick in based on the tax owed, and interest is added to late payments. You can read the full breakdown on the GOV.UK penalties page. The rules are strict and appeals aren’t guaranteed, so the safest approach is to file accurately and on time, which is exactly what we help you do.
Yes. Once you authorise us as your registered HMRC agent, we can prepare and submit your self assessment tax return on your behalf. You’ll still approve the final figures before anything is filed, and you remain legally responsible for your own return, but the heavy lifting is ours. Being your agent also means we can deal with HMRC directly if any questions come up.
It depends on your circumstances, but typically we’ll ask for records of your income (self-employment, rental, dividends, savings interest, and so on), details of any expenses you want to claim, your P60 or P45 if you’ve been employed, pension and Gift Aid contributions, and your Unique Taxpayer Reference (UTR). If you’re not sure what counts, don’t worry. We’ll give you a clear checklist so nothing important gets missed.
You generally need to file if you’re self-employed and earned over £1,000, receive rental income, are a company director with untaxed income, earn over £150,000, are caught by the High Income Child Benefit Charge, or have untaxed income from savings, investments, or disposals. There are other triggers too. HMRC’s free online checker will confirm it in a couple of minutes, or you can ask us and we’ll tell you in a quick conversation.
Yes. While our five offices are across South and West Wales, we work with clients right across the UK. Our service runs comfortably online, so wherever you are, you can send us your records securely, approve your return remotely, and speak to your dedicated accountant by phone or video. You get the benefit of a genuinely local, relationship-led firm without needing to be on the doorstep.
Absolutely, and try not to panic. HMRC sometimes raises queries or opens a review, and it doesn’t automatically mean anything is wrong. As your agent, we can respond to HMRC on your behalf, explain what they’re asking for, and help you provide the right information. Having an experienced accountant handle the correspondence usually takes a lot of the stress out of the situation.
The earlier the better. Appointing a tax return self assessment accountant well before the January rush means we have time to gather your records properly, spot planning opportunities, and file without a last-minute scramble. It also spreads the workload and avoids the stress that builds as the deadline nears. That said, if you’ve left it late, get in touch anyway. We’re used to working to tight timescales.
