FreshBooks is loved by freelancers for its invoices, but when MTD for Income Tax is the priority, the picture changes fast.
FreshBooks built its reputation on beautiful invoices and client billing, and it earned that reputation honestly. But if you are a UK sole trader who needs to file quarterly updates to HMRC under Making Tax Digital, you are not really shopping for an invoicing tool; you are shopping for a compliance tool. Those are different products, and that distinction is the single biggest deciding factor in this comparison.
The short verdict: if invoicing and project billing are the core of your business, FreshBooks is genuinely excellent and TapTax cannot replace it. But if your priority is low-cost, fuss-free MTD for Income Tax compliance on your phone, TapTax wins on every measure that matters, including price, UK tax focus and the actual filing experience.

FreshBooks is a Canadian-American product. Its pricing is set in US dollars and converted at checkout, which means your monthly direct debit is not a fixed number. When the pound weakens against the dollar, as it did sharply in 2022 and has done periodically since, your FreshBooks bill quietly rises without any change to your plan. Lite is around £15 a month at current rates; Plus is around £25 a month. But those figures can drift.
Over a full year at current rates, FreshBooks Lite costs roughly three times more than TapTax Starter. That is around £120 more per year, every year, for software whose strongest features (invoicing, project tracking, client portals) you may never use if you are a sole trader who just needs to stay compliant and capture expenses on the go. If you want to understand what your actual tax bill might look like before you commit to any software, the sole trader tax calculator is a good place to start.
FreshBooks serves a global market. Its product roadmap is driven by freelancers in North America, Australia and Europe, not by the specific demands of HMRC's MTD ITSA rollout. UK MTD for Income Tax support exists in FreshBooks, but it is not the beating heart of the product the way it is in TapTax.
TapTax was built from day one with one question in mind: how do you make quarterly HMRC filing feel as painless as possible for a sole trader on their phone between jobs? That focus shows in the experience. Bank transactions arrive via your connected feed, the AI categorises them, you confirm or adjust, and you file with one tap. The quarterly update goes directly to HMRC.
For a deeper look at how different tools handle this filing requirement, the best MTD software for sole traders in 2026 is worth reading before you decide.
FreshBooks has a well-designed mobile app, genuinely one of the better ones in its category. But it is optimised for creating invoices, chasing payments and logging billable hours on the move. Those are real jobs that real freelancers need to do.
TapTax's mobile experience is optimised for something different: capturing a receipt at the till, confirming a bank transaction on the train home, and submitting a quarterly update without sitting down at a laptop. If your working day does not involve sending invoices but does involve buying materials, driving to jobs and quietly dreading tax season, TapTax's stripped-back focus is a feature, not a limitation.
Self-employed drivers, for example, can use the mileage tax calculator alongside TapTax's expense tracking to make sure every business mile is accounted for before the quarterly deadline.
This page would not be doing its job if it did not say this clearly: FreshBooks is better than TapTax for invoicing. Full stop. It handles recurring invoices, late payment reminders, client portals, project budgets, billable time and multi-currency billing in a way TapTax deliberately does not attempt.
If you are a graphic designer, web developer or consultant who bills clients monthly, tracks time against projects and needs a paper trail of proposals and invoices, FreshBooks earns its cost. TapTax has no invoicing at all, by design, because building a focused MTD tool and building a full billing platform are genuinely incompatible goals if you want to keep the price at £4.99.
The question is whether you are paying for features you actually use. If you send more than a handful of invoices a month, FreshBooks's billing tools may well be worth the premium. If you rarely invoice, or handle invoicing separately through a spreadsheet or another tool, you are paying for capability you never touch.
It is also worth checking your PAYE situation if you have any employment income alongside your sole trader work: the tax code checker can flag whether HMRC has the right code on file before you file your first quarterly update.
You almost certainly do not send polished invoices through your accounting software; you quote in person, take payment by bank transfer, and your main admin headache is expenses and quarterly HMRC filing. TapTax Starter at £4.99 a month does everything you need. FreshBooks would cost you roughly three times more for features you would never open.
FreshBooks's invoicing, time tracking and client portal are genuinely useful to you, and the price difference may be justified. But be aware that your MTD quarterly filing is not FreshBooks's priority, and you may find the compliance workflow less smooth than a UK-native tool. Some freelancers in this position use FreshBooks for billing and a separate MTD tool for compliance, though that adds cost and admin.
TapTax's Free tier lets you get started with zero commitment. You can set up bank feeds, categorise expenses and understand your income without paying anything. FreshBooks has no free tier. If you want to build good habits now so that mandatory MTD compliance from April 2026 does not catch you off guard, starting with TapTax costs nothing.
Mileage is one of the most commonly under-claimed expenses for sole traders. TapTax's mileage tracking integrates with the mileage tax calculator to make sure you are capturing every deductible mile. FreshBooks tracks mileage too, but it is not built around HMRC's specific approved rates the way a UK-native tool is.
FreshBooks wins on invoices. TapTax wins on MTD. Know which job you are actually hiring for before you pay.
FreshBooks is not a bad product. It is a very good product for the specific job it was designed to do: helping freelancers and small agencies look professional, bill clients efficiently and track billable time. If that description fits your working life, it is worth the cost.
But if you are a UK sole trader whose main anxiety is quarterly HMRC filing, expense categorisation and staying MTD-compliant without spending your Sunday evenings on spreadsheets, FreshBooks is solving a different problem. TapTax costs less, files directly to HMRC with one tap, and was built specifically for the compliance challenge you are actually facing.
With MTD for Income Tax becoming mandatory for those earning over £50,000 from April 2026, now is a sensible time to make sure your software is pulling in the same direction as HMRC, not just looking good on an invoice.
TapTax connects to your bank, categorises expenses automatically, and submits quarterly updates to HMRC. Free plan, no card required.
