What we handle

Every flavour of UK self-assessment.

We file for sole traders, landlords, directors, contractors, locums, investors, non-residents and high earners. One fixed fee per return.

Sole trader & self-employment

SA103 (full or short), every legitimate business expense, capital allowances on equipment, use-of-home costs, mileage. Class 2/4 NIC optimisation and payments on account planning.

Landlord / rental income

SA105 with Section 24 mortgage restriction correctly applied, Form 17 split for jointly-owned, furnished holiday let qualification, and CGT on disposals. Multi-property portfolios handled routinely.

Directors & high earners

Director's salary + dividends, BIK, tapered personal allowance (>£100k), pension input carry-forward, Child Benefit tax charge, loss relief and every applicable allowance.

Capital gains & foreign income

SA108 for CGT (property, shares, crypto, business assets), SA106 for foreign income, non-resident/split-year treatment, remittance basis, double-taxation relief. All in one filing.

What goes wrong elsewhere

The mistakes that cost people money.

Most overpaid or underfiled returns share a few common patterns. Here's what we fix.

Filed on time but incomplete

Missing pension contribution carry-forward, missing Form 17 split, missing CGT annual exemption. The return files fine — but you've overpaid tax by £500–£5,000.

Late filing penalties compounding

£100 at 1 day late, £10/day after 3 months, £300 or 5% of tax at 6 months, and more at 12. We rescue late filers and often get penalties reduced or waived with reasonable excuse.

Payments on account over-paid

Previous year was a bumper year so HMRC estimates this year the same. Not true? You can reduce payments on account — most people don't, and HMRC keeps the cash until next January.

No forward tax planning

Filed, sent back, file again next year. Nobody tells you to contribute to a SIPP in March to drop below £100k, or to realise losses before disposal. We plan for next year while filing this one.

"My previous accountant filed on time every year but nothing extra. AudTax looked back at the last three returns, found £3,200 in overpaid tax I'd no idea about, and reclaimed it. Best phone call I've had in years."

Common questions

Questions we hear about self-assessment.

I've never filed before — do I need to?

You need to file if you're self-employed earning >£1k, a landlord, a high earner (>£100k), a director of a Ltd, received >£10k dividends/savings, have foreign income, or sold a second home or investment. The 20-min call will clarify.

I'm years behind — can you help?

Yes. We handle late-filing rescue routinely — including multi-year catch-ups. We'll file every outstanding return, negotiate penalty reductions where there's a reasonable excuse, and agree a Time to Pay arrangement with HMRC if needed.

What about Making Tax Digital for self-assessment?

MTD for ITSA starts April 2026 for self-employed and landlords with income >£50k (then £30k from April 2027). Quarterly digital updates + end-of-year statement. We're fully MTD-ready — every new client is set up for it.

Can you file CGT on property disposals?

Yes — including the separate 60-day residential property CGT return that runs alongside your SA. We regularly file these for landlords selling BTLs and second-home owners.

How much does a self-assessment return cost?

From £250+VAT for a simple sole trader/landlord return. £400–£600 for complex multi-source returns (high earner with rentals, dividends, CGT and foreign income). Included for free on our monthly accountancy plans.
