Overview

More than just a form to fill in

Self-assessment can feel straightforward on the surface, but the reality is more complex. Miss a source of income, overlook an allowable expense, or miscalculate a capital gain and you could face an unexpected tax bill — or worse, a penalty from HMRC.

At DKAT, we don't just complete your return. We review your entire financial picture, identify every relief and deduction you're entitled to, and present you with a clear, plain-English summary before anything is submitted. Our goal is always the same: the lowest legally payable tax liability, filed correctly and on time.

Whether you have a straightforward employment return with some rental income, or a complex picture involving multiple businesses, overseas assets and capital disposals, we have the expertise to handle it — at a fixed, transparent fee.

Why choose DKAT for your tax return?

  • Fixed fees agreed upfront — no hourly billing surprises
  • Dedicated accountant who knows your history year on year
  • We typically save clients more than our fee in tax
  • Responses to your queries within one business day
  • Fully MTD-ready, cloud-based and paperless where possible

Who This Service Is For

Self-assessment for every situation

👤
Sole Traders & Freelancers
If you run your own business, self-employment income must be declared and any allowable expenses claimed correctly to avoid overpaying.
🏠
Landlords
Rental income must be reported, but you can offset mortgage interest (within limits), maintenance costs, letting agent fees and more.
💼
Company Directors
Directors receiving dividends in addition to salary must file a self-assessment return each year, even if PAYE is already deducted.
📈
Investors
Capital gains from property, shares or other assets above your annual exempt amount must be reported and the tax calculated accurately.
✈️
Non-Residents & Expats
If you have UK income but live abroad, or have recently moved to the UK, your tax position needs careful handling under non-residency rules.
💷
Higher Earners
Income over £100,000 triggers the loss of your personal allowance, and those earning over £60,000 with child benefit face a specific tax charge.
What We Cover

Every aspect of your tax return

We handle every type of income, relief and calculation your return might need — nothing is left to chance.

01
Self-Employment Income & Expenses
Complete SA103 schedules for sole traders and freelancers. We review your expense records and ensure every allowable business cost — from equipment to home office use — is correctly claimed.
02
Rental & Property Income
Full Schedule E calculations for UK property, including deductions for mortgage interest (within the 20% basic rate limit), maintenance, insurance, letting agent fees and periods of vacancy.
03
Dividends & Investment Income
Accurate reporting of UK and overseas dividends, savings interest, bond gains and ISA income to ensure your tax-free allowances are fully utilised and nothing is over-reported.
04
Capital Gains Tax
We calculate gains on property, shares, business assets and other disposals, applying your annual exemption, losses brought forward, and any available reliefs such as Private Residence Relief or BADR.
05
Foreign Income & Non-Residency
Overseas employment, rental or investment income requires careful handling under the remittance basis or arising basis rules. We ensure HMRC receives the correct information and that double tax relief is applied where available.
06
HMRC Correspondence & Enquiries
If HMRC opens an enquiry into your return, we handle all communication and representation on your behalf — protecting your position from the very first letter.
02
Tailored Document Checklist
We send you a personalised checklist based on your specific circumstances — so you know exactly what to gather. No generic lists, no unnecessary requests.
03
Thorough Preparation
We prepare your return in full, reconciling all income, calculating reliefs and flagging any anomalies for discussion before submission.
04
Plain-English Walkthrough
Before we file, we send you a clear summary: what you owe, why, and when payment is due. We are available to explain any figure in detail.
05
Submission & Confirmation
Once you approve, we submit via HMRC's official online system and send you the confirmation receipt and a copy of the completed return for your records.
06
Year-Round Advice
Our service doesn't end at filing. We proactively flag changes in tax law that may affect you and advise on actions you can take during the tax year to reduce next year's bill.

FAQ

Frequently asked questions

Do I need to file a self-assessment return?
+
You must file if you're self-employed with income over £1,000, earn over £100,000, have untaxed income (e.g. rental or investment), are a company director, have sold assets and made gains above your exempt amount, or have claimed child benefit with income over £60,000. If you're unsure, we'll advise within 24 hours.
What is the filing deadline?
+
The online self-assessment deadline is 31 January following the end of the tax year (5 April). Paper returns must be filed by 31 October. Payment of any tax owed is also due by 31 January. We always work well ahead of these deadlines.
What documents will I need?
+
The specific documents depend on your income sources, but typically include your P60, P11D (if applicable), self-employment income and expense records, bank statements, rental income and expense records, dividend vouchers, and details of any assets sold. We send you a tailored checklist.
What if I have missed previous years?
+
We can prepare and file outstanding returns for prior years. HMRC will charge automatic penalties for late filing (starting at £100), but these are fixed penalties — the key is to file as soon as possible. We'll also help minimise any interest on unpaid tax.
Can you deal with HMRC directly on my behalf?
+
Yes. With a 64-8 authorisation, we become your nominated agent and can deal with HMRC entirely on your behalf — including responding to letters, handling enquiries, and accessing your online HMRC account to check records and submissions.
What if I've received a penalty notice?
+
Don't ignore it. Contact us immediately and we'll review the notice, assess whether there are grounds for appeal, and if so, lodge a formal appeal on your behalf. In many cases, penalties can be reduced or eliminated where there is a reasonable excuse.
