Our expertise covers

Everything in this service, in one bill.

  • 01

    SA100 preparation and online filing

    We prepare your full return, including the SA103 (self-employment), SA105 (UK property), SA106 (foreign income), SA108 (capital gains) and SA102 (employment) supplementary pages, and file it online with HMRC. Paper deadline is 31 October; the online deadline is 31 January following the tax year end (5 April). We aim to file well ahead so your liability is never a 31 January shock.

  • 02

    Sole traders and the self-employed

    Accounts drawn up from your records on Xero, QuickBooks, FreeAgent or Sage, with the right basis-period figures. We claim the £1,000 trading allowance where it beats actual expenses, and apply the 45p-per-mile rate for the first 10,000 business miles (25p thereafter) where simplified mileage is the better option for you.

  • 03

    Landlords and property income

    Rental profit calculated correctly under the finance-cost restriction, mortgage interest is no longer deducted as an expense but given as a 20% basic-rate tax reducer. We apply the £1,000 property allowance where useful, handle furnished holiday lets, and report jointly-held property on the correct split.

  • 04

    Capital gains and the 60-day rule

    Disposals of property, shares and crypto reported with the £3,000 annual exempt amount applied. Residential property gains carry an 18% (basic-rate) or 24% (higher-rate) charge and a separate 60-day HMRC report-and-pay obligation after completion, miss it and penalties run. We handle both the 60-day return and the year-end SA108.

  • 05

    Directors, dividends and side income

    Company directors, high earners and anyone with dividend or savings income filed accurately. The dividend allowance is just £500, taxed at 10.75%, 35.75% and 39.35% across the bands. We also handle the High Income Child Benefit Charge and ensure PAYE-taxed income is reconciled, so you don't pay twice.

  • 06

    Payments on account and MTD for Income Tax

    We calculate your two payments on account (due 31 January and 31 July) and reduce them where your income has fallen, protecting your cash flow. From April 2026, Making Tax Digital for Income Tax becomes mandatory for those with qualifying income over £50,000, quarterly digital updates instead of one annual return. We'll move you onto compatible software before it bites.

Why it pays off

What you actually get.

  • A named, ACCA-qualified accountant

    You deal with one qualified person who knows your situation, not a call-centre queue or a different name each time. ACCA-regulated, so the advice is held to a professional standard.

  • Fixed fees from £99, no hourly billing

    Transparent pricing at £99, £199 or £499 depending on complexity, agreed up front. No surprise invoices for a phone call or an extra schedule, and a 30-day money-back guarantee if you're not happy.

  • Replies within 72 hours, all year

    A guaranteed 72-hour reply on every query, not just in January. Tax questions don't wait for filing season, and neither do we.

  • We chase the deadlines, not you

    We track your 31 January filing deadline, your 31 July payment on account, and the 60-day CGT window so nothing slips into a penalty. You get reminders in good time, not a panicked email on 30 January.

  • Works with your existing software

    Already on Xero, QuickBooks, FreeAgent or Sage? We work in whatever you use, no forced migration, and keep you MTD-ready for April 2026.

  • Rolling monthly, no lock-in

    Engage us on a rolling monthly basis with no long tie-in. Stay because the service is good, not because a contract traps you.

Common questions

Frequently asked questions.

You must file if you were self-employed earning over £1,000, a company director with untaxed income, a landlord with rental income above £1,000, or earned over £150,000 in employment income. You also need to file if you received over £10,000 in dividends or savings income, or if you or your partner earn over £60,000 and claim Child Benefit. If you're unsure, we'll check your position for free.

There's an automatic £100 penalty the day after the deadline, even if you owe no tax. After 3 months it becomes £10 per day for 90 days (up to £900), then a further £300 or 5% of tax owed at 6 and 12 months. Interest on unpaid tax runs at 7.75% from 1 February. We submit two weeks early so HMRC delays never become your problem.

Office costs, business travel and mileage (45p per mile for the first 10,000 miles), a proportion of home utilities if you work from home, phone and broadband, professional subscriptions, training in your existing trade, and equipment. The £1,000 trading allowance covers small earnings without receipts. We go through your bank statements line by line so nothing legitimate gets missed.

If your tax bill is over £1,000, HMRC requires two advance payments toward next year's tax, one on 31 January (alongside the balancing payment for the year you've just filed) and one on 31 July. Each is 50% of your previous year's bill. That's why your first January after a profitable year feels brutal. We forecast it months ahead so you can set the cash aside.

Self-Assessment is included in our Essentials plan from £99/month for sole traders, and in every Premium plan for directors. One-off Self-Assessment filing for non-clients starts at £150 for straightforward returns. Every return is reviewed by an ACCA-qualified accountant before submission, and we offer a 30-day money-back guarantee if you're not happy.
