Sound familiar?
Still doing your own tax return every January?
Most sole traders manage their own self assessment for years before realising how much they are overpaying or, more urgently, how close they have cut the deadline. Add bookkeeping that slips behind, a VAT registration threshold you are not sure you have crossed, and the picture becomes harder to ignore. The admin is not going anywhere on its own.
- Self assessment filed in a rush, with allowances probably left on the table
- No clear picture of what your tax bill will be until it arrives
- Bookkeeping months behind, making every financial question a guessing game
What sorted looks like
You hand over the information, we handle the rest. Your return is filed accurately, your allowable expenses are claimed properly, and you know your tax position before HMRC does. Considerably less to worry about.
- Your self assessment prepared thoroughly, with all relevant allowances and reliefs applied
- Tax bill calculated early, with payments on account explained so nothing catches you off guard
- Books kept up to date monthly, so year-end is a formality rather than a scramble
- Fixed fee of £150 for self assessment. No hidden extras, no hourly billing.

What makes the difference for sole traders
There are plenty of accountants. Here is what actually matters when you are running a business on your own.
Your Tax Bill Known Early
We prepare your self assessment well ahead of the January deadline, so you know what you owe before HMRC’s reminder arrives. Payments on account are explained clearly so the following July does not come as a shock. Surprises are largely avoidable when the numbers are done on time.
Fixed Fees, No Guessing
Self assessment is a fixed £150. There is no hourly rate ticking in the background while you gather receipts or ask questions. You know the cost before you start, which is, frankly, the way it should be.
Qualified, Regulated, and Insured
Our qualified accountants are backed by professional indemnity insurance and the firm is authorised by Companies House as an Authorised Corporate Service Provider (ACSP), with anti-money laundering supervision by HMRC. The credentials are real and verifiable.
Up and running in four steps
Starting is straightforward. Most clients are set up and have their first return in progress within a few days of getting in touch.

Share Your Information
We send a simple checklist of what we need: income figures, expense records, and any HMRC correspondence. If your records are incomplete, we will tell you exactly what is missing rather than leaving you to guess.
We Do the Work
Your return is prepared, reviewed, and sent to you for approval before anything goes to HMRC. You review the figures, confirm they are correct, and we file. You do not need to log into Government Gateway yourself.
Know Where You Stand
Once filed, you know your tax liability, when it is due, and what to expect next year. Less of your evenings spent on paperwork, and a clear picture of your finances going forward.
“Working with Wings Online Filings Ltd has been an absolute pleasure. They are highly communicative, supportive, and provide a responsive, cost-effective service that perfectly suits my small architecture practice. I switched from another accountant about a year ago and haven’t looked back since.”
Things sole traders usually ask us first
I work across a few different income sources. Can you handle a more complex self assessment?
Yes. Multiple income streams, whether employment alongside self-employment, rental income, dividends, or savings interest, are all covered under a single return. We ask you to list all sources at the outset so nothing is missed, and the fixed £150 fee applies to the complete return rather than each income type separately. If your situation is genuinely complex (for example, capital gains from a property disposal), we will say so upfront and quote accordingly.
What does the self assessment service cost, and what is included?
The fixed fee is £150 for a sole trader self assessment. That covers preparing your SA100 and SA302, reviewing your allowable expenses, claiming all applicable reliefs, advising on payments on account, and submitting to HMRC. There is no additional charge for questions during the process. Bookkeeping and VAT are quoted separately based on your requirements.
My records are a bit of a mess. Can you still help?
Most clients arrive with records in some state of disarray, and that is not unusual. We will tell you clearly what we need and flag anything that is missing rather than making assumptions. If catch-up bookkeeping is needed before the return can be completed, we will quote for that separately and transparently, so you know the total cost before any additional work begins.
Is there a contract? What happens if I decide to leave?
There is no long-term contract. For a one-off self assessment, you pay a fixed fee for that year’s return, with no ongoing commitment. If you are on a monthly bookkeeping arrangement, you can end it with reasonable notice and you leave with your records in good order, transferred in a format you can use elsewhere. Nothing is held back.
Do you actually know the expenses sole traders in my industry can claim?
We work with sole traders across a wide range of sectors, including freelancers, consultants, contractors, tradespeople, healthcare professionals, and creative practitioners. The allowable expenses differ by industry and by how you work, particularly around home office, mileage, equipment, and professional subscriptions. We ask the right questions at the start rather than applying a generic checklist, which is where a material number of sole traders miss out on legitimate deductions.
How do payments on account work, and will you explain them?
Payments on account are advance payments toward your next year’s tax bill, due in January and July. They catch many sole traders off guard because the January bill is effectively one and a half times what they expected. We calculate them when we file your return, explain exactly what is due and when, and advise whether it is worth applying to reduce them if your income has fallen. You will not be left to work it out from the HMRC guidance notes on your own.
