TapTax vs TaxZap
for self-employed tax

TaxZap and TapTax are, of all the tools in this comparison set, probably the most alike. Both are low-cost, mobile-first, AI-powered apps that use open banking to pull in your transactions and make self-employed tax feel less painful. The differences are in heritage and emphasis: TaxZap is an Irish fintech, born around automated tax refunds, now expanding into the UK with a swipe-style filing experience and a newer Making Tax Digital app. TapTax is UK-built from the ground up for Making Tax Digital, freemium, and focused specifically on UK sole traders and the quarterly cadence that becomes mandatory from April 2026.

Here is the honest version. TaxZap is a credible, well-funded rival with real scale in Ireland (reportedly 120,000-plus clients) and a genuinely slick, gamified experience. TapTax's edge is being UK-native, having a permanently free tier, and going deep on the trades and niche professions other tools ignore. We will not pretend TapTax is listed on the HMRC MTD software directory, because its production recognition is still pending. Read on for where each genuinely fits.

What HMRC's own directory says about TaxZap

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. HMRC spells the listing Taxzap.

HMRC MTD for Income Tax directory, scraped 9 August 2026. Feature flags are vendor-declared. Vendor site

No permanent free tier. UK MTD ships as a separate app, Making Tax Digital by Taxzap, launched March 2026. The legacy one-off Self Assessment service is around £99.

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.

Three points, one of which needs a caveat rather than a conclusion.

TaxZap is graded 0 of 16 on the tax-return items, with 15 in development. That is the largest gap between marketing and current grading of any product we looked at closely: every year-end item is promised for the 2026-27 return and none is graded shipped. It can file quarterly updates today.

It is graded ready on all three income sources including foreign property, which puts it in the minority of 63 of 127 (50%) that can report an overseas rental.

HMRC lists no mobile app for TaxZap, and that flag looks wrong. TaxZap is an app-first business and shipped a dedicated UK MTD iOS app in March 2026. Mobile flags on the directory are vendor-declared and imperfect in both directions, and HMRC's own data carries that caveat. We are reporting the listing as it stands rather than treating it as evidence that no app exists, and this is one to check on the vendor's own site.

It is graded not included on calendar update periods, so quarters run on HMRC's 6 April to 5 April cycle only.

The single biggest difference: UK-native MTD versus Irish-born refunds

TaxZap's roots are in Ireland, where it built a large user base by automating tax refunds for employed and self-employed people. Its signature is an AI- and open-banking-driven, gamified experience, a swipe-style interface sometimes described as "Tinder for tax", that analyses your transactions and aims to get a return filed in under ten minutes. Backed by a reported £2.2m seed round, it has been bringing that model to the UK with a Self Assessment service and, more recently, a Making Tax Digital app for non-VAT-registered sole traders and landlords.

TapTax starts from a different place: it is built in the UK, specifically for Making Tax Digital for Income Tax. It connects to your existing bank via open banking, auto-imports transactions, applies AI categorisation, lets you snap receipts and tracks mileage, then rolls all of that into one-tap quarterly MTD updates. The philosophy is "Tap. File. Done." Both apps are mobile-first and automation-led; the distinction is that TapTax is purpose-built around the UK quarterly cadence and the specific needs of UK sole traders, rather than adapting a refund-led product from another market.

Pricing in detail: what you actually pay

TaxZap's pricing depends on the product and the market, and some figures are clearer than others, so we have flagged what is well-established versus reported. TapTax is a single freemium subscription.

On ongoing software cost, the meaningful difference is that TapTax has a permanently free tier you can stay on, while TaxZap's MTD app gives a free first month and then moves to a paid subscription. On a one-off UK Self Assessment, TaxZap's reported ~£99 is the comparison point, similar to other accountant-light filing services.

Before you choose either, the TapTax sole trader tax calculator gives you a free, no-signup estimate, and if your numbers look off it is often a wrong code, so check your tax code too.

Where TaxZap genuinely wins

It would be dishonest to gloss over TaxZap's real strengths, so let us state them plainly.

Scale and a track record. TaxZap has built a large user base in Ireland, reportedly working with well over 100,000 clients, and is venture-backed. That maturity and momentum are reassuring, and it means the product has been battle-tested at volume.

A genuinely slick, gamified experience. The swipe-style, open-banking-driven flow is designed to make filing fast and almost playful, with claims of sub-ten-minute returns. If you find tax intimidating, that approachable UX is a real draw.

Refund heritage. TaxZap grew up finding people money back, so its instinct is geared toward surfacing reliefs and rebates. For anyone who suspects they have overpaid, that refund-first DNA is appealing.

Where TapTax genuinely wins

A permanently free tier. TapTax's free tier lets you connect your bank and test the full flow without paying, and you can stay on it. TaxZap's MTD app offers a free first month and then a subscription. For cost-sensitive sole traders, free that stays free is a real difference.

UK-native, built for MTD. TapTax is designed in the UK around Making Tax Digital for Income Tax specifically, the quarterly updates, the final declaration, the 2026/27 rates and the nuances of UK sole-trade and property income. A tool built for one market's rules, rather than adapted from another, tends to fit the edge cases better.

Depth for trades and niche professions. TapTax goes deep on the long tail other apps overlook, from construction and CIS to dozens of specific trades, with tailored calculators and guidance. If you want help that speaks to your actual line of work, that coverage matters. Start with the quarterly planner and the plain-English guide to MTD for sole traders.

Everything-included automation. Open-banking import, AI categorisation, receipt scanning and mileage tracking are all in TapTax at each tier, with no per-task fees, so your records build themselves as you trade rather than being assembled at year-end.

Allowable expenses and tax angles both tools should capture

Whichever you pick, the same UK rules decide your bill for 2026/27. The personal allowance is £12,570, basic rate 20% to £50,270, higher 40% to £125,140 and additional 45% above, with the allowance tapering between £100,000 and £125,140 (an effective 60% band). Class 4 National Insurance is 6% between £12,570 and £50,270, then 2%, with Class 2 settled through Self Assessment. Scottish taxpayers use an S code with six bands (19/20/21/42/45/48%); Welsh taxpayers use a C code at rates that currently match the rest of the UK, while NIC stays UK-wide.

Key reliefs to make sure your software captures: the £1,000 trading allowance (if expenses are below this, claim the allowance instead); the VAT registration threshold of £90,000 on a rolling 12-month basis; the £500 dividend allowance with rates of 10.75/35.75/39.35%; and for landlords, mortgage-interest relief restricted to a 20% tax credit on SA105 (note the Furnished Holiday Lettings regime was abolished from April 2025). If you have multiple income streams, model them together with the multiple-income calculator. Both TapTax and TaxZap use open banking to help surface deductible expenses as you go.

If you work in construction under CIS, contractors deduct 20% from registered subcontractors (30% if unregistered) on labour, which usually leaves subcontractors due a refund through Self Assessment. TapTax tracks the deductions as you go so the refund position is visible before year-end, and goes deep on CIS specifically; a refund-led tool like TaxZap is naturally oriented toward surfacing that rebate too.

Who should choose which

If you want a fast, gamified app with proven scale

TaxZap. Its swipe-style, open-banking experience and large Irish user base make it a slick, credible choice, especially if a refund-first flavour appeals.

If you are a UK sole trader heading into mandatory MTD

TapTax. It is built in the UK specifically for the April 2026 quarterly cadence, with a free tier to test the full flow before paying and one-tap filing every quarter.

If you want the lowest ongoing software cost

TapTax. Its permanently free tier and £4.99 Starter plan sit below TaxZap at around £8.99 a month, with everything included and no per-task fees. To be straight about it though, TapTax is at the cheap end of this market rather than the cheapest in it: Clear Books Free, TaxHeaven Angel and My Tax Digital file for £0, and MTD 4 Income Tax is £20 a year.

If you work in a trade or niche profession

TapTax. Its depth on construction, CIS and dozens of specific trades, with tailored calculators and guidance, is something a general refund app does not focus on.

The bottom line

TaxZap and TapTax are close cousins: both low-cost, both mobile-first, both AI- and open-banking-powered. TaxZap brings Irish scale, a gamified experience and a refund heritage, now pointed at the UK. TapTax brings a UK-native, MTD-first design, a permanently free tier and real depth for sole traders and trades.

If a fast, playful, well-funded app with a proven track record appeals, TaxZap is a genuine option worth trying. If you want a tool built specifically for UK Making Tax Digital, free to start and ready for one-tap quarterly filing as the rules tighten through 2026 to 2028, TapTax is the sharper fit, and its free tier means you can judge it against your own numbers before spending a penny.
