TapTax vs Xero: Which Is Better for Sole Traders?

Xero is one of the most recognised names in accounting software. If you are researching MTD tools, it is probably on your list. But Xero was built for businesses with employees, invoices and complex accounts, not for a sole trader who needs to file quarterly and move on.

Before anything else, a correction that most Xero comparisons still have not made. Xero retired its Starter, Standard and Premium plans for new customers in September 2024 and migrated every subscriber onto a new lineup. If you are reading a comparison that prices Xero Starter at £15 or Standard at £30, it is describing a plan line that has not been sold for roughly two years. This page uses the current line, checked in August 2026.

That correction matters in Xero's favour, and it is worth saying so up front. The cheapest current plan, Simple at £7 plus VAT a month, is the cheapest a major accounting brand has ever been for a UK sole trader. "Xero is expensive" is no longer the argument it was in 2024.

The argument that survives is a different one, and this page is built on it.

TapTax vs Xero at a Glance

TapTax is MTD-compatible and going through HMRC's recognition process, so it did not appear on the find-MTD-software directory at our 9 August 2026 scrape. Xero did. If you need to file a live submission this month, that difference decides it, and this page would rather say so in the first table than bury it.

Who Is Each Tool Built For?

Xero is built for growing businesses

Xero serves businesses that need to send invoices, reconcile accounts, run payroll, manage multiple currencies, collaborate with accountants, track projects and generate detailed financial reports. It handles everything from a startup's first invoice to a medium-sized company's full accounting workflow.

For businesses that genuinely need these capabilities, Xero is excellent. The ecosystem of integrations, the accountant collaboration features and the depth of reporting are industry-leading.

TapTax is built for sole traders

TapTax serves self-employed individuals who need to comply with Making Tax Digital without becoming amateur accountants. It handles income tracking, expense categorisation, receipt scanning and quarterly HMRC filing: the things a sole trader actually needs, and nothing else.

For a plumber, a tutor, a freelance designer, a delivery driver or a personal trainer, TapTax covers the full MTD requirement without the overhead of learning an accounting platform.

The question is not which tool is better in absolute terms. It is which tool is better for your situation.

Xero's Current Plan Line, and Where It Steps Up

As checked in August 2026, the UK plans are Simple at £7 a month, Ignite at £16, Grow at £37, Comprehensive at £50 and Ultimate at £65, all excluding VAT. Add 20% for your real cost: Simple is closer to £8.40 a month, Ignite £19.20 and Grow £44.40.

The step that decides your real price

Simple is deliberately thin. Ignite is the first plan that behaves like the Xero people picture when they say "Xero", and it carries the constraint worth understanding: Ignite is reported as capped at 20 invoices and 10 bills a month, with everything above it offering unlimited invoices and bills.

One caveat on where that number comes from, because it is load-bearing. Xero's own plan pages returned errors on every attempt to read them in August 2026, so the cap figure comes from independent UK pricing trackers that agree with each other rather than from Xero itself. Treat it as corroborated rather than confirmed, and check it on Xero's site before you rely on the exact numbers.

The shape of the argument does not depend on the precise figure. Xero's entry tier limits invoicing and the tier above it does not, which means an actively invoicing sole trader is choosing between £16 and £37 a month excluding VAT, not between £7 and £16. That step, from roughly £230 a year to roughly £533, is larger in cash terms than the old Starter-to-Standard step it replaced.

One timing point. Xero has confirmed a further UK price rise from 1 September 2026. Every figure on this page is an August 2026 snapshot and that date is close, so check the live rate before signing anything.

The Number That Does Not Depend on the Cap

If you want one fact to decide on, and you would rather it were not a figure we had to caveat, it is this one.

HMRC publishes a feature grid for every product on its find-MTD-software service, using its own three-state scale of ready now, in development or not included. We scraped all 127 listings on 9 August 2026.

Xero	Not included	Ready now	Ready now	Ready now	Android; Apple iOS	2/16

HMRC lists what each vendor declares. Feature flags, mobile-app support in particular, are vendor claims rather than verified facts, and listings change. Check with the vendor before you buy. Data: HMRC find-MTD-software service (tax.service.gov.uk), scraped 9 August 2026.

HMRC grades 2 of Xero's 16 tax-return items ready: UK interest and foreign interest. The other 14 are in development. Quarterly updates cover your business income and expenses. The 16 return items are the year-end work that has to reach the return before it is finished: employment income, dividends, state and private pensions, partnership income, pension contributions, the Construction Industry Scheme, charitable giving, capital gains, student loan, marriage allowance, voluntary Class 2 National Insurance and the High Income Child Benefit Charge.

So the whole field is thin here and Xero is not an outlier, but its own peer group is well ahead: QuickBooks, FreeAgent, Clear Books, Kletta, untied, RentalBux, TaxHeaven and My Tax Digital are graded at 15 of 16.

TapTax's honest grade on the same axis is mid-pack, roughly six to eight of the 16 items live, and that is our own estimate rather than an HMRC grade, because TapTax has no row on that directory yet. Pensions income, CIS, capital gains and partnership income are still to come. Ahead of Xero today, well behind the leaders. The full picture for all 127 products is in our analysis of the HMRC MTD directory.

Xero does win one row outright, and it is one most big brands lose: foreign property. Only 63 of 127 (50%) of the directory can report an overseas rental at all. If you have one, that single row may outrank everything else on this page.

Pricing: What You Actually Pay Over a Year

TapTax pricing

The real comparison

The honest version is that this is no longer one comparison, it is three.

Against Simple, £49 a year versus roughly £101 including VAT. TapTax is about half the price and has a free tier where Xero has none, but the gap is a takeaway lunch a month rather than a reason to switch on its own. At this end the decision is about fit, not cost.

Against Ignite, £49 against roughly £230. That is where price starts doing real work, and it is the comparison most sole traders evaluating "Xero" are actually in, because Simple is thinner than what they picture.

Against Grow, £49 against roughly £533. That is a serious ongoing expense for someone whose entire tax complexity is recording income, categorising expenses and filing four quarterly updates.

Which of the three you are in depends almost entirely on how much you invoice. That is why the cap matters even though we cannot confirm it precisely: it is the thing that moves you between comparisons.

MTD Filing Experience

Xero and TapTax will both submit quarterly updates. The difference is in how that filing feels.

TapTax: one-tap filing

When a quarterly deadline approaches, TapTax presents a summary of your income and expenses for the quarter. You review the figures, confirm they look correct and tap submit. The entire process takes under five minutes if you have been reviewing transactions weekly.

The interface is designed around speed. No multi-screen navigation, no accounting jargon, no complex menus. Review. Confirm. Submit. Done.

Xero: multi-step process

Filing in Xero requires navigating to the MTD section, selecting the correct period, reviewing the submission data and confirming. It works, but the process involves more steps and sits within a larger, more complex interface.

If you are already comfortable with Xero's navigation, this is not a significant drawback. If you are new to accounting software, the additional complexity adds friction to a task you need to do four times per year.

The practical difference

For someone who uses Xero daily for invoicing and reconciliation, MTD filing is a minor addition to an existing workflow. For someone who only opens their accounting software when it is time to file, every extra step and unfamiliar menu is a barrier to getting it done on time.

Expense Tracking and Categorisation

This is the area where TapTax and Xero differ most.

TapTax: AI-powered categorisation

TapTax uses AI expense categorisation to analyse each bank transaction and suggest the correct HMRC category. The AI considers the merchant name, transaction amount, description and your history of corrections.

You review each suggestion with a swipe: right to confirm, left to change. The AI learns from your corrections over time, getting more accurate the longer you use it.

HMRC category mapping is automatic. Expenses go straight into the categories required for quarterly filing: travel, office costs, cost of goods, professional fees and so on. There is no manual mapping step.

Xero: rule-based categorisation

Xero uses bank rules. You create rules that automatically categorise transactions from specific vendors. For example, you might set a rule that categorises every transaction from "Shell" as a travel expense.

This works well once set up, but it requires manual configuration. You need to create a rule for each vendor or transaction pattern. New vendors or unusual transactions are not automatically categorised and need manual attention.

Xero does not map to HMRC categories automatically. You may need to ensure your chart of accounts aligns with HMRC's required categories, or handle mapping when preparing your MTD submission.

Which approach is better for sole traders?

AI categorisation requires less setup and less ongoing maintenance. You do not need to create rules or configure anything, and it starts working from your first transaction. For sole traders who want to spend as little time as possible on bookkeeping, that is the significant advantage.

Rule-based categorisation gives you more granular control, which matters for businesses with complex accounting needs. For a sole trader with straightforward income and expenses, that control adds complexity without adding value.

Mobile Experience

TapTax: mobile-first

TapTax is designed for mobile from the ground up. Every feature, from expense review and receipt scanning to categorisation and quarterly filing, works fully on your phone. The swipe interface is designed for thumb navigation.

This matters because most sole traders are not sitting at a desk during the day. A plumber between jobs, a tutor between sessions, a delivery driver between drops. You need to review expenses and scan receipts wherever you are.

Xero: web-first with mobile companion

Xero's primary experience is its web application. The mobile app exists and handles basic tasks, such as approving transactions, photographing receipts and viewing reports, but it is a companion to the desktop experience rather than a replacement.

Some tasks in Xero require switching to a desktop browser. Complex reconciliations, reporting configuration and some settings are not available on mobile. If you work exclusively from your phone, you will hit limitations.

What Xero Does That TapTax Does Not

Being honest about TapTax's limitations is important. Xero offers a wide range of features that TapTax deliberately does not include:

Invoicing: create, send and track professional invoices, set up recurring invoices and accept online payments. Note the tier ladder here rather than assuming the entry plan covers it.

Payroll: process employee payroll as an add-on, handling PAYE, pensions and payslips.

Multi-currency: track transactions in multiple currencies, useful for businesses working with international clients.

Detailed financial reporting: balance sheets, cash flow statements, profit and loss, aged receivables and payables, and dozens of custom reports.

Accountant collaboration: your accountant can access your Xero account directly, review your books, make adjustments and prepare year-end accounts. UK practice fluency in Xero is close to universal, which is worth more than any monthly saving if someone else does your books.

Project tracking and purchase orders: track time and costs against clients, and manage supplier orders.

Third-party integrations: connect to hundreds of apps for inventory, CRM, e-commerce and more.

If you need any of these, Xero is the better tool. TapTax does not offer them and there are no plans to add them. They are outside the scope of what a sole trader MTD tool needs to do.

What TapTax Does That Xero Does Not

AI expense categorisation: Xero's rule-based system requires manual setup and does not learn from your behaviour. TapTax's AI analyses transactions and improves over time.

One-tap quarterly filing: Xero's MTD filing requires multiple navigation steps. TapTax reduces it to a single review-and-submit action.

Mobile-first design: TapTax is built for the phone first. Xero is built for the browser with a mobile app added on.

Purpose-built simplicity: no chart of accounts, no accounting jargon, no complex setup.

A free tier: Xero has none at any plan level, which HMRC's directory confirms. TapTax has one.

More of the year-end return, today: roughly six to eight of the 16 items against Xero's 2, on our own estimate against HMRC's published grade for Xero.

Common Scenarios: TapTax or Xero?

"I am a plumber who invoices commercial clients"

Choose Xero, and price the right tier. You need invoicing, which TapTax does not offer at all. Just do the tier arithmetic before the brand comparison: if your invoice volume clears Ignite's reported cap you are pricing Grow at £37 plus VAT, roughly £533 a year, not the £7 headline that brought you to the page.

"I am a personal trainer paid directly by clients"

Choose TapTax. Your clients pay you directly by cash, bank transfer or card, and you do not invoice them. You need to track income, categorise expenses and file quarterly. TapTax handles that from a phone for £49 a year.

"I am a freelance designer with five regular clients"

It depends, and five is the interesting number. Five invoices a month sits comfortably inside Ignite's reported cap, so Xero at £16 plus VAT is a real option if you want invoicing in the same place. If they pay on completion without formal invoices, TapTax covers the MTD requirement for a quarter of that.

"I am a delivery driver"

Choose TapTax. Your income arrives from the platform, your expenses are fuel, phone and vehicle costs, and you need categorisation and quarterly filing. Xero's invoicing, payroll and reporting are irrelevant to your situation.

"My accountant uses Xero"

Consider Xero. If your accountant manages your books there, switching to TapTax means they lose direct access. Discuss it first. If you handle everything yourself and only see your accountant for year-end advice, TapTax works independently.

"My return has pensions, dividends or capital gains in it"

Check both carefully, and look wider. Xero is graded 2 of 16 ready now, TapTax is at roughly six to eight on our own estimate, and the 15-of-16 cohort on HMRC's directory is ahead of both.

"I need to file a live submission this month"

Choose a product HMRC lists. TapTax is MTD-compatible and going through HMRC's recognition process, so it had no row on the directory at our 9 August 2026 scrape. Xero did.

The Verdict

For MTD compliance only: TapTax

If you are a sole trader tracking income and expenses and filing quarterly, TapTax is faster, simpler and cheaper at every tier, with a free entry point Xero does not have. Against Ignite that is roughly £180 a year; against Grow it is closer to £480.

For full accounting: Xero

Invoicing, payroll, multi-currency, detailed reports, accountant collaboration and foreign property. These are genuine capabilities TapTax does not provide, and they justify the price for users who need them.

The honest tiebreaker

Xero at £7 plus VAT is cheap enough that price alone no longer settles this. What settles it is scope and the year-end. If you want an accounting platform, buy the platform and budget for the tier you will actually land on. If you want the tax filing done from your phone in a few taps, you are buying a lot of platform you will never open.
