Sound familiar?
Still not sure what your tax bill is going to be?
Most people who do their own self assessment spend a good part of January working out what they owe, hoping they have not missed anything, and filing at the last moment. The 31 January deadline does not move, and the penalties for missing it start at £100 on day one. Beyond the deadline, there is also the question of whether the return was correct in the first place.
- Filing at the last minute without knowing if the figures are right
- Unsure which income sources to include or which allowances apply
- No visibility on payments on account, so the July bill comes as a surprise
What a properly prepared return looks like
Your return is prepared by a qualified accountant who checks every figure, claims what you are entitled to, and submits on time. You know your tax liability before HMRC contacts you, not after.
- Return prepared, reviewed, and filed well ahead of the January deadline
- All income sources reviewed and all applicable allowances correctly claimed
- Payments on account explained so July holds no surprises
- Fixed one-off fee of £150, with no hidden costs and no annual contract

Everything covered for £150
The fixed fee covers preparation, review, and submission of your full self assessment return. There is nothing extra to pay for the items listed below.
SA100 and SA302 Preparation
We prepare both your personal tax return (SA100) and your tax calculation (SA302) in full. All income sources are accounted for, whether that is employment, self-employment, property, dividends, or savings interest. You see the figures before anything is submitted.
Included as standardAllowances, Reliefs, and Planning
We check that every allowance and relief you are entitled to has been applied, including the trading allowance, property allowance, pension contributions, and Gift Aid where relevant. We also explain your payments on account so you can plan ahead for the July and January instalments.
Included as standardHMRC Submission and Confirmation
Once you have reviewed and approved the return, we submit it directly to HMRC on your behalf and provide you with confirmation. Your filing history stays clean, your deadlines are met, and you have a record you can refer back to at any time.
Included as standardClients across the UK, different situations
We work with sole traders, contractors, landlords, and company directors. These are three reviews from clients with different backgrounds and circumstances.
Switched Accountants and Would Not Go Back
“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.”
Everything Done Quickly, No Stress at All
“Everything was done quickly and properly, with no stress at all. If you need a service that’s reliable and easy to work with, I definitely recommend Prads and Wings Online Filings Ltd!”
Professional, Responsive, Genuinely Reliable Partner
“They were professional, responsive, and prompt throughout, and handled our company accounts and tax return smoothly. Excellent service and genuinely reliable, exactly what you want in an accounting partner.”
What makes the difference in practice
There are a lot of accountants who will file your return. These are the things that clients notice once they have worked with us.
Your tax position explained, not just filed
We do not just submit the numbers. We explain what your return shows, what you owe and why, and what you can expect to pay in future. For many clients, this is the first time they have genuinely understood their self assessment position. Which is, frankly, the way it should be.
Qualified accountants, fixed and transparent pricing
Your return is handled by a qualified accountant, not passed to a junior or processed automatically. The fee is £150, fixed, and covers everything described on this page. There are no add-ons for multiple income sources or extra correspondence with HMRC.
Filed well before the deadline, not on it
We work to get returns prepared and submitted with time to spare, so you know your liability early and can plan accordingly. The January scramble is largely avoidable when the process starts in good time. We will let you know what we need and when.
Up and running in four straightforward steps
Most clients are surprised by how little they need to do. We handle the bulk of the work once you have sent us the basics.
Get in touch for a quote
Fill in the short form on this page or give us a call. We will confirm the fixed fee and let you know exactly what information we need from you. There is no commitment at this stage.
Send us your documents
We will tell you specifically what to send: P60s, P11Ds, rental income summaries, bank interest statements, or anything else relevant to your situation. Everything is shared securely online, no printing or posting required.
We prepare and review the return
A qualified accountant prepares your SA100 and SA302, checks the figures, applies your allowances and reliefs, and sends the draft to you for approval. We explain anything that needs clarification before you sign off.
Filed and confirmed, job done
Once you approve, we submit directly to HMRC and send you confirmation. You know what you owe, when it is due, and what to expect in the months ahead. Considerably less to think about than before you got in touch.
“Prads at Wings online filings went above and beyond to help us out in a timely and professional manner, flexible online meetings, extra work to fix my mistakes. Would recommend 100%”
Things clients usually ask before getting started
I have income from several different sources. Is that still covered by the £150 fee?
Yes. The fixed fee of £150 covers self assessment returns with multiple income sources, including employment income, self-employment profits, rental income, dividends, savings interest, and capital gains where they apply. If your situation is more complex, for example if you have overseas income or HMRC is querying a previous return, we will tell you before starting and agree any additional cost with you upfront. There are no surprises.
What exactly is included in the £150 fee?
The fee covers preparation of your SA100 personal tax return and SA302 tax calculation, review of all applicable allowances and reliefs, a clear explanation of your liability and payments on account, and submission directly to HMRC. You will also receive confirmation once the return has been accepted. The fee does not cover ongoing bookkeeping or VAT, but those can be quoted separately if needed.
My records are a bit disorganised. Does that cause a problem?
Not necessarily. We work with clients who arrive with records in varying states of order, and we can help you identify what is missing and how to pull it together. If there is a significant amount of catch-up work required, we will tell you what is involved and whether there is any additional cost before we start. Most clients find it is more straightforward than they expected.
Do I have to commit to an ongoing service?
No. The self assessment service is a one-off fixed fee with no annual contract. If you want us to handle your return year after year, that is a straightforward conversation each time. If you only need this year’s return sorted, that is fine too. You are not locked in to anything.
I have missed a filing deadline. Is it too late to use you?
No, it is not too late. Late filing penalties start at £100 on the day after the deadline and increase the longer the return remains outstanding, so it is worth getting it submitted as soon as possible. We can prepare and file late returns and can also help you understand the penalties already incurred. If you have a reasonable excuse, we can advise on whether it is worth putting that to HMRC.
Can you advise on reducing my tax bill, or is it just a filing service?
Both. We prepare and file the return, and as part of that we check that all allowances and reliefs have been applied correctly. If there are planning points worth discussing, such as pension contributions, timing of income, or the structure of a side income, we will flag them when reviewing your figures. Tax planning is a separate advisory service for more involved situations, but straightforward points are included in the conversation as a matter of course.
Get your self assessment sorted before the deadline arrives.
A fixed fee of £150 covers your full return, all income sources, applicable allowances, and HMRC submission. No long-term contract, no hidden costs, and a qualified accountant handling the work.
