TapTax vs FreeAgent: Which MTD Tool Suits Sole Traders Better?

FreeAgent is a popular choice among UK sole traders and freelancers, especially those who bank with NatWest or RBS. It is a solid, UK-built accounting platform with a loyal following.

But FreeAgent was built as a full accounting tool long before Making Tax Digital existed. MTD support was added later, on top of an existing product designed for invoicing, time tracking, and Self Assessment filing. For sole traders whose only goal is quarterly MTD compliance, that means paying for (and navigating through) features they do not need.

TapTax was built for MTD from day one. This comparison lays out the honest differences so you can decide which tool fits your situation.

TapTax vs FreeAgent at a Glance

The comparison hinges on two questions: Do you bank with NatWest or RBS? And do you need invoicing and time tracking?

The NatWest Factor

FreeAgent's pricing story is unlike any other accounting tool. NatWest (which owns FreeAgent) offers it free or heavily discounted to business banking customers. If you have a NatWest or RBS business account, FreeAgent may cost you nothing.

This is genuinely compelling. Free accounting software with invoicing, time tracking, and MTD support is hard to argue against, if you already bank with NatWest or RBS.

The catch

The discount ties your accounting software to your bank. If you switch banks in the future (because another bank offers better terms, because NatWest changes their business account fees, or because you simply prefer a different provider) your FreeAgent costs jump from £0 to £31 per month overnight.

This creates a subtle lock-in. You might stay with NatWest not because it is the best bank for your business, but because switching would cost you £372 per year in software fees on top of whatever the new bank charges.

How it distorts the market

The NatWest partnership makes FreeAgent appear to be the cheapest option in many comparison articles. But the price only applies to a subset of users. For sole traders who bank with Barclays, Starling, Monzo, HSBC, Lloyds, Tide, or any other provider, FreeAgent costs £31 per month, one of the most expensive options available.

When comparing tools, it is important to compare like-for-like. TapTax costs £4.99 per month regardless of where you bank.

Pricing Without the Bank Deal

Removing the NatWest variable gives a clearer picture:

TapTax

FreeAgent (without NatWest/RBS)

TapTax Starter vs FreeAgent: £59.88 vs £372 per year.

That is a difference of over £310 per year. Over three years, choosing TapTax saves you more than £930. Even compared to FreeAgent at the discounted NatWest rate of £14.50/mo (£174/year), TapTax Starter is still cheaper at £59.88/year.

The price difference reflects a fundamental design choice. FreeAgent includes features (invoicing, time tracking, project costing, detailed reporting) that cost money to build and maintain. If you use those features, you are getting value. If you do not, you are subsidising capabilities you never touch.

MTD Filing: One-Tap vs Multi-Step

Both tools are MTD-compatible. Both submit quarterly updates to HMRC. The filing experience, however, is quite different.

TapTax: Built for MTD from the start

TapTax was designed around the MTD quarterly filing workflow. When a deadline approaches, the app presents a summary of your income and expenses for the quarter. You review the figures, confirm, and tap submit. The process takes under five minutes.

The entire interface is oriented around this cycle: record transactions, categorise them, file when due. There is no separate "MTD section" to find because MTD is the product.

FreeAgent: MTD added to an existing product

FreeAgent started as a Self Assessment and invoicing tool. MTD support was added as the legislation developed. This means the MTD filing workflow sits within a larger, more complex product.

Filing a quarterly update in FreeAgent requires navigating to the correct section, reviewing the submission data, and confirming. It works, but the process involves more screens and sits alongside features (invoicing, time sheets, project tracking) that are irrelevant to the filing task.

For FreeAgent users who already use the platform daily for invoicing and time tracking, this is not a significant issue. MTD filing is just another task within a familiar tool. For sole traders who only open the software to file quarterly, the extra complexity is unnecessary friction.

Mobile Experience

TapTax: Mobile-first

TapTax is designed for the phone first. Every feature works fully on mobile: reviewing transactions, categorising expenses with swipes, scanning receipts, and filing quarterly updates. The interface uses thumb-friendly navigation and a card-based design.

This is important for sole traders who work on the go. A builder checking expenses between jobs, a tutor reviewing income between sessions, a driver scanning a fuel receipt at the petrol station. These are all mobile moments.

FreeAgent: Desktop-oriented

FreeAgent is primarily a web application. It has a mobile app, but the app handles a limited subset of tasks. Creating invoices, managing contacts, and viewing reports are possible on mobile, but the experience is not as polished or complete as the web version.

For detailed work (setting up bank rules, configuring projects, reviewing financial reports) FreeAgent users typically switch to a desktop browser. If you prefer managing finances on a computer, this is fine. If you want to do everything from your phone, you will hit limitations.

AI and Automation

TapTax: AI-powered categorisation

TapTax uses AI expense categorisation that analyses each bank transaction and suggests the correct HMRC category. The AI considers the merchant name, transaction amount, description, and your history of previous categorisations.

You review suggestions with a swipe: right to confirm, left to change. The AI learns from your corrections over time. After two to three months of use, accuracy typically reaches 90-95% for regular spending patterns.

HMRC category mapping is automatic. The AI assigns expenses directly to HMRC's required categories (travel, office costs, cost of goods, professional fees, and so on) without manual configuration.

FreeAgent: Rule-based categorisation

FreeAgent uses bank rules for categorising transactions. You create rules that automatically assign categories to transactions based on vendor name or description. For example, a rule might categorise every "Shell" transaction as fuel.

This approach works once set up, but:

• You need to create rules manually for each vendor
• New vendors or unusual transactions are not handled automatically
• The system does not learn or adapt over time
• HMRC category mapping may require manual alignment

Receipt scanning

Both tools support receipt scanning. TapTax uses built-in OCR to extract details from photographed receipts. FreeAgent also allows receipt capture through its mobile app. The core functionality is comparable, though TapTax's mobile-first design makes the capture workflow slightly faster.

What FreeAgent Does That TapTax Does Not

Being transparent about this is important. FreeAgent offers several features that TapTax does not include:

Invoicing: Create professional invoices, set up recurring invoices, track payment status, and send automatic payment reminders. This is one of FreeAgent's strongest features and a primary reason many freelancers choose it.

Time tracking: Log billable hours against clients or projects. This feeds directly into invoicing, making it easy to bill clients for time spent.

Self Assessment integration: FreeAgent has years of experience with Self Assessment filing. The transition to MTD builds on this foundation.

Accountant collaboration: Your accountant can access your FreeAgent account directly for review and year-end adjustments.

Project costing: Track income and expenses per project to see profitability at a project level.

Detailed financial reports: Profit and loss, balance sheet, tax timeline, aged debtors, and more.

If you need invoicing or time tracking in the same tool as your MTD filing, FreeAgent is the stronger option. These are genuine capabilities that TapTax does not provide.

What TapTax Does That FreeAgent Does Not

TapTax has its own advantages that FreeAgent cannot match:

AI expense categorisation: FreeAgent's rule-based system requires manual setup and maintenance. TapTax's AI works from day one and improves over time without configuration.

One-tap quarterly filing: The MTD filing workflow is reduced to a single review-and-submit action. No navigating through accounting menus to find the filing section.

Mobile-first design: Everything works fully on your phone. TapTax is not a desktop tool with a mobile app bolted on. The mobile experience is the primary experience.

Bank-independent pricing: TapTax costs the same regardless of where you bank. No lock-in, no dependency on a banking relationship for affordable software.

Lower price: At £4.99/mo, TapTax is the cheapest fully-featured MTD tool available. Even against FreeAgent's discounted NatWest pricing, TapTax costs less.

Faster setup: Under five minutes from download to first use. No chart of accounts, no accounting configuration, no learning curve.

Who Should Choose Which

Choose FreeAgent if:

You bank with NatWest or RBS. The free or discounted pricing makes FreeAgent excellent value, and you get a full accounting tool at no extra cost. Even so, consider whether you actually use the extra features or whether the simpler approach of TapTax would save you time.

You need invoicing in the same tool. If you bill clients regularly and want invoicing, expense tracking, and MTD filing in one place, FreeAgent handles all three.

You need time tracking. Freelancers who bill by the hour benefit from FreeAgent's time tracking feature, which connects directly to invoicing.

You already use FreeAgent. If your workflow is established and FreeAgent is working for you, switching has a cost in time and adjustment. Switching makes most sense at the start of a new tax year.

Choose TapTax if:

You want the simplest MTD experience. TapTax is designed for one purpose: making quarterly filing as fast and painless as possible. If you do not need invoicing, time tracking, or full accounting, TapTax eliminates the complexity.

You do not bank with NatWest or RBS. Without the bank partnership discount, FreeAgent costs £31/mo, over six times the price of TapTax Starter. The extra features do not justify the cost if you do not use them.

You prefer mobile. If you want to manage everything from your phone, TapTax's mobile-first design is significantly better than FreeAgent's desktop-oriented approach.

You want AI categorisation. If the idea of manually creating bank rules for every vendor sounds tedious, TapTax's AI handles categorisation automatically and improves over time.

Budget matters. At £4.99/mo, TapTax is the most affordable automated MTD tool regardless of your bank. Over a year, you save over £310 compared to FreeAgent's standard price.

The Bottom Line

FreeAgent is a capable, UK-built accounting tool that has served freelancers well for years. Its NatWest partnership makes it a compelling choice for sole traders who happen to bank with the right provider.

But for the majority of sole traders (those who bank elsewhere, those who do not invoice clients, and those who just want the fastest route to MTD compliance) TapTax is the better fit. It costs less, it is simpler, it files faster, and it uses AI to automate the tedious parts of expense categorisation.
