Who it's for

If your tax doesn't fit on a P60, you probably need this.

  • Sole traders & freelancers

    Running your own business or working under a trading name. We handle the SA103 and Class 4 NI.

  • Landlords

    UK rental income, allowable property expenses, and the section-24 mortgage interest restriction handled correctly.

  • Company directors

    Dividend income, P11D benefits, salary outside PAYE, and any other untaxed sources — joined up correctly.

What's included

A return that's right the first time.

  • Full SA100 + supplementary pages

    SA103 self-employment, SA105 property, SA108 capital gains, SA109 residence — whatever your year needs.

  • Plain-English tax summary

    A pre-submission summary showing your income, deductions and final tax position before anything goes to HMRC.

  • Every allowable deduction

    We claim what you are entitled to — and tell you what you cannot, with the reason in plain English.

  • Payments-on-account advice

    We tell you what's due in July and January and why, so the bills don't catch you out.

  • Filed copy and HMRC receipt

    A copy of the return and HMRC's confirmation, both straight to your inbox the day we file.

  • Year-round reminders

    Email reminders for self-assessment deadlines, payments on account, and any HMRC follow-up.

Making Tax Digital for Income Tax — staged rollout from April 2026.

Sole traders and landlords with qualifying income above £50,000 must keep digital records and submit quarterly updates from 6 April 2026. £30,000 from April 2027. £20,000 from April 2028. If MTD applies to you, we'll set up the software and handle the quarterly submissions.

How it works

From shoebox to filed in four steps.

  1. Send us your figures

    P60s, P11Ds, dividend vouchers, rental statements, expense receipts — spreadsheet, PDF or a shoebox. Whatever you have.

  2. We prepare the return

    You get a draft with your tax position explained line by line. Ask questions in plain English; get plain-English answers.

  3. You approve, we file

    One reply confirms approval. We file with HMRC the same day; their confirmation goes straight to you.

  4. Reminders, year-round

    We remind you when payments on account fall due — and we're there when HMRC asks anything.

FAQ

The questions we get asked.

  • What if I'm late filing?

    We still help. We'll file as soon as your figures are ready and tell you what the late-filing penalty looks like before HMRC does. Late penalties stack — £100 immediately, then daily charges after three months, then percentage-based after six and twelve.

  • Do I need a self-assessment if I'm a company director?

    Not automatically — directors only need to file if they have untaxed income to declare (dividends, rental income, P11D benefits over the threshold, etc.). We'll check your situation in five minutes on the phone.

  • What if I owe more tax than expected?

    We tell you the figure before you approve the return — no nasty surprises after filing. If the bill is awkward, we can help you set up a Time to Pay arrangement with HMRC.

  • When do I need to register for self-assessment?

    By 5 October following the tax year in which you started self-employment, became a landlord, or otherwise needed to file. We can do the registration for you in the same conversation.

  • What about Making Tax Digital for Income Tax?

    From 6 April 2026, sole traders and landlords with qualifying income above £50,000 must keep digital records and submit quarterly updates. The threshold drops to £30,000 from April 2027 and £20,000 from April 2028. If MTD applies to you, we'll set you up with compatible software and handle the quarterly submissions as part of the service.

Pricing

A fixed fee per return.

Agreed upfront, with no surprises at filing time. Supplementary pages (property, capital gains, residence) are quoted separately so you only pay for what your year actually needs.

Ask for a quote

Deadlines: 5 October to register, 31 October to file on paper, 31 January to file online and pay. We take new clients from April and stop accepting work after 15 January.
