QuickBooks hooks you with a discount, then doubles the price. Here is what UK sole traders need to know before they sign up.
QuickBooks is one of the most advertised accounting tools in the UK, and it is very good at advertising. The 75% introductory discount looks compelling right up until month four, when the standard rate kicks in and your £6/mo trial quietly becomes £22/mo. If you are a sole trader trying to stay MTD-compliant without paying for features you will never use, that bait-and-switch pricing deserves a hard look before you hand over your card details.
This page gives you a straight comparison of TapTax and QuickBooks specifically for UK sole traders filing under MTD for Income Tax. The short verdict: QuickBooks is a capable full-accounting platform and worth it if you genuinely need invoicing, VAT management or employee payroll. If you do not need any of that and just want clean, fast, accurate quarterly filings to HMRC from your phone, you are paying for a lot of seats you will never sit in.

QuickBooks regularly runs promotions offering 50% or 75% off for the first three to six months. It is a smart way to get you into the ecosystem before the real price lands. At £12/mo post-promo, QuickBooks Self-Employed costs £144 a year. That is more than double TapTax Starter at £59.88. Simple Start at £22/mo costs £264 a year, and if you need VAT returns you are at Essentials, which is £32/mo, or £384 a year.
Over five years on Simple Start versus TapTax Starter, the gap is over £1,000. That is real money for a sole trader who just wants their quarterly submissions filed correctly.
You can estimate your own tax position with TapTax's sole trader tax calculator to see whether the difference in cost is genuinely justified by extra features you would actually use.
QuickBooks Self-Employed is the tier most sole traders land on after clicking an ad. It is the cheapest, and it is the most limited. You cannot file VAT returns from it. You cannot produce a balance sheet. HMRC has signalled that the mileage-and-expenses workflow in this tier is not a substitute for full MTD ITSA compliance. If your accountant needs to reconcile your books properly, they may well tell you to upgrade.
That upgrade, from Self-Employed to Simple Start, roughly doubles your monthly bill. It is not a bug; it is the business model. QuickBooks is a full-service accounting platform built for businesses with employees, multiple revenue streams and complex reporting needs. The Self-Employed tier is a loss-leader designed to move you up the stack.
If you are curious how VAT compliance figures into your costs, the TapTax VAT calculator can give you a quick sense of your liability before you decide which software tier you actually need.
TapTax is built from the ground up for MTD for Income Tax. Connect your bank, categorise your transactions (the AI handles most of it), and tap to submit your quarterly update directly to HMRC. There is no accountant-in-the-middle step, no desktop export, no PDF to email. The whole workflow lives in the app.
QuickBooks Simple Start and above can submit MTD updates, but the product was not designed with quarterly ITSA filing as its primary job. The setup is heavier, the interface carries overhead from all the SME features you do not need, and the mobile experience, while functional, feels like a desktop product that has been adapted rather than one built for your phone first.

Most sole traders do not sit at a desk reconciling accounts. They check their bank app between jobs. TapTax is designed for that moment: open the app, the new transactions are waiting, one or two taps to categorise them, done. Receipt scanning is built in rather than bolted on. The quarterly submission screen is a single page, not a twelve-step wizard.
QuickBooks mobile is genuinely capable, particularly for invoicing on the go. But the app carries the weight of the full platform; navigating to the specific corner of it that handles your quarterly ITSA update is not obvious the first several times you try it.
If you are unsure what tax code you are on and whether your PAYE income is being counted alongside your self-employment income, it is worth a quick check with the TapTax tax code checker before you start reconciling anything.
Honestly, QuickBooks is the better tool in several situations. If you send invoices regularly and want your income tracked automatically against those invoices, QuickBooks handles this elegantly and TapTax does not do it at all. If you have registered for VAT, QuickBooks Simple Start and above handles Making Tax Digital for VAT and MTD for Income Tax under one roof. If you have a business bank account through a provider with a native QuickBooks integration and want everything in one place, that cohesion has real value.
If you have an accountant who already uses QuickBooks and wants to work in it directly, staying on QuickBooks makes obvious sense. The collaboration features are strong and the accountant ecosystem around it is large.
TapTax deliberately does not compete on those dimensions. It does not have invoicing and it never will; that is a design choice, not a limitation the team has not got round to fixing.
You need MTD for Income Tax compliance from April 2026. You send maybe two or three informal quotes a month and do not invoice formally. TapTax Starter at £4.99/mo gives you everything you need: bank feeds, AI categorisation, quarterly filing, and £84 a year back in your pocket compared to QuickBooks Self-Employed. The best MTD software guide for 2026 covers this profile in detail.
QuickBooks Simple Start or Essentials is worth the cost. The invoicing workflow, VAT returns and MTD ITSA filings from a single platform save you switching between tools. The price premium is genuinely justified here.
TapTax's free tier costs nothing and connects to your bank. You can assess whether the categorisation and filing workflow suits you before spending a penny. QuickBooks has no equivalent free entry point.
You do not need a full accounting suite. You need digital records and quarterly updates. TapTax handles exactly that at a fraction of the QuickBooks price, with less setup friction and a mobile experience that actually fits around your working day.
QuickBooks is excellent software for small businesses. It is also significantly more than most sole traders need, and the promotional pricing makes it easy to discover that fact the hard way.
If your working life involves formal invoicing, VAT returns or multiple income streams that need consolidated reporting, QuickBooks earns its price. Pay for what you actually use.
If you are a sole trader whose main compliance job is keeping clean records and filing quarterly updates to HMRC under MTD for Income Tax, TapTax gives you a product that was built specifically for that job, on your phone, for less than a fiver a month. The promotional discount on QuickBooks will expire. The £4.99 on TapTax will not.
TapTax connects to your bank, categorises expenses automatically, and submits quarterly updates to HMRC. Free plan, no card required.
