Self Assessment Tax Return Devon

Your Devon self assessment, handled.

Most people who need a self assessment return know they have to file — they just keep putting it off until January. The paperwork builds up, the deadline closes in, and the worry about getting it wrong does not help. Fixed monthly fee, ICAEW chartered, same-day replies.

  • Self assessment filed accurately and on time — no last-minute panic
  • Every allowable deduction found — you pay only what you actually owe
  • Know your tax bill well before HMRC sends the payment reminder
  • HMRC correspondence handled by someone who answers the same day

No long-term contract. If it is not working after three months, you leave with a filed return and nothing owed.

Sound familiar?

Still not sure what you owe HMRC this year?

Self assessment returns have a habit of appearing on the horizon and then staying there until January makes them unavoidable. Records that need digging out, income from multiple sources that needs pulling together, deductions you suspect exist but are not certain about. It is all manageable — it just takes longer the further into the tax year you leave it.

  • No clear idea what the tax bill will be until it is nearly due
  • Records not properly organised, making an accurate return difficult to prepare
  • Allowable expenses probably being missed — paying more tax than necessary

What a sorted return looks like

Your tax position becomes visible well before the January deadline. Records are reviewed, income is categorised correctly, and every allowable deduction is identified. You know your bill in advance — and it is accurate.

  • Tax liability known months before it is due — no last-minute surprises
  • Records reviewed and organised so the return is correct from the start
  • Every allowable deduction identified — you pay what you owe, not more
  • A fixed fee agreed upfront — no invoice larger than expected arrives after

What Devon clients say about their returns

Both came to us with a self assessment return that needed sorting, often under time pressure. Here is what they said afterwards.

★★★★★

Being a self employed stone mason sadly paper work is not my strong suit. And after a late cancellation from my normal accountant I had to find help. With late notice I contacted swift accounting and book keeping. Kieran was the person assigned to me to help with my tax return and at the start of Jan not much time to file my return before potential fines incurred. He went above an beyond to help good communication through emails an working even on a Saturday night to complete my return. I cannot thank him enough he made the process super easy an relaxed I will 100% be using them again in the future. Thank you.

What you get

What your self assessment fee covers

Three things that keep your return accurate, your tax bill known in advance, and HMRC off your plate — for one fixed fee.

01

Self Assessment Tax Return

Your return prepared accurately, every allowable deduction identified, and filed with HMRC before the deadline. Income from employment, self-employment, property, dividends or any combination is handled. You will know your liability before it is due — not the day the payment is demanded.

Fixed fee, no extras
02

Tax Planning and Deduction Review

Before the return is filed, your income and expenses are reviewed to ensure nothing allowable is missed. For sole traders and the self-employed, that means business mileage, home working, equipment, professional subscriptions — properly categorised and claimed. Paying less than you should is as much of a problem as paying more.

Included as standard
03

Ongoing Bookkeeping and Records

If your records need sorting before the return can be prepared, that is where most people start. Monthly bookkeeping on Xero keeps everything current so there is no scramble the following January. One fixed monthly fee covers both the bookkeeping and the return when it comes around.

Available as an add-on
What clients say

Devon clients trust Swift with their returns

Why Swift

Why Devon residents choose Swift

There is no shortage of accountants who will file a self assessment return. Here is what makes the difference when you actually need an answer.

📋

Your bill known well in advance

Once your records are current, your tax liability becomes visible throughout the year rather than arriving as a surprise in January. Most clients have a clear picture three to four months before the payment is due — long enough to set money aside, not just react. Which is, frankly, the way it should be.

💬

Questions answered the same day

Whether it is a deductibility question, a letter from HMRC that needs interpreting, or a query about your payment on account, you will get an answer the day you ask. Not logged and queued — answered. That consistency shows up in almost every review we have received.

🔒

One fixed fee, agreed upfront

Your fee is agreed before any work starts and does not change. No hourly billing, no unexpected charges for a phone call, no invoice that arrives larger than quoted. Your accounting costs are as predictable as your other fixed outgoings.

Getting started

Up and running in four steps

From first enquiry to a filed return — no complicated forms, no lengthy onboarding, no waiting weeks for a response.

1

Send your enquiry

Fill in the form on this page. Kieran reads every enquiry personally and responds the same day with a clear next step. No automated holding messages, no junior handling initial contact.

2

A short discovery call

Around twenty minutes to understand your income sources, current records and what needs preparing. By the end of the call you will know exactly what is covered, what it costs and what happens next. No vague proposals sent a week later.

3

Records reviewed and prepared

Your income and expenses are reviewed, categorised correctly and any gaps identified. If records need catching up, that is handled at this stage. You confirm the return before it is submitted — nothing goes to HMRC without your approval.

4

Filed — and you know what comes next

Your return is filed, your liability is confirmed, and any payment on account obligations are explained clearly. From here, your tax position is visible throughout the year. January stops being the month you dread.

Questions

Questions Devon clients usually ask first

It is why most people come to us. Getting records up to date takes a little longer at the start and may cost slightly more — we will tell you exactly what that looks like before any work begins. Once the return is filed and records are current, keeping them that way is straightforward.
Your income and expenses are reviewed before the return is prepared, not after. For self-employed individuals that means mileage, home working, equipment, professional fees, subscriptions and anything else that qualifies under HMRC rules. Nothing is left to chance or assumption.
Once your records are current, your liability becomes visible throughout the year rather than only at year-end. Most clients have a reasonable picture three to four months before the January payment deadline — enough time to plan, not just react.
No. If you only need a one-off return prepared and filed, that is available as a standalone service. For clients who want ongoing bookkeeping included, arrangements are month-to-month with a month’s notice to cancel. No long-term contracts, no exit penalties.
