Sage for Self-Employed Tax vs TapTax (2026): Costs, MTD, Verdict

Sage has been a fixture of UK accounting since the 1980s. It processes payroll for companies with dozens of staff, handles multi-currency invoicing, and integrates with procurement systems most sole traders have never heard of. If you are a self-employed electrician trying to file quarterly updates to HMRC without losing a Sunday afternoon to software you barely understand, that heritage is not a selling point. It is the problem.

The central question on this page is not which product is better in the abstract. It is whether a sole trader needs a full accounting platform or a focused MTD compliance tool. The answer shapes everything: the price you pay, the time you spend on setup, and how many screens you navigate to do something as simple as categorising a fuel receipt in a supermarket car park.

What HMRC's own directory says about Sage

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 122 listings on 5 August 2026. Sage appears four times, which matters when you are reading reviews: they do not all grade the same.

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 5 August 2026.

TapTax's own position, stated plainly rather than left to inference: TapTax is MTD-compatible and is going through HMRC's recognition process, so it did not appear on the find-MTD-software directory at our 5 August 2026 scrape and has no row in the grades above. If you need to file a live submission this month, choose a listed product. On the return-items axis TapTax is mid-pack at roughly six to eight of 16, ahead of every Sage listing's 0 but behind the leaders.

Three observations.

Every Sage listing is graded 0 of 16 on the tax-return items, with 14 to 15 in development. All four can keep digital records and file quarterly updates. None is graded able to complete a single year-end item yet. Sage has committed to closing that for the 2026-27 return.

Foreign property is not included on any of them, so an overseas rental is out across the Sage range.

Only Sage Sole Trader & Landlord Free carries the free version flag, and Sage50 is the one listing without a mobile app.

For context, Sage is far from alone on the first point:

The defining issue: Sage was not built for you

Sage Accounting is a serious, capable product. It has earned its reputation over decades and it genuinely serves the small business owner who has staff to pay, a bookkeeper to satisfy and an accountant who trained on Sage in the 1990s. The feature set reflects that audience: purchase orders, VAT returns, multi-currency, payroll, detailed profit and loss reporting, journal entries.

For a sole trader whose actual job is plumbing, tutoring, driving or freelancing, almost none of that applies. You need to connect your bank account, let software sort your income and expenses into the right boxes, scan a few receipts, and then file your quarterly MTD update without it taking longer than making a cup of tea. Sage can do all of that, but it makes you walk through the rest of the building to get there.

The UX issue is not a small thing. Sage's interface carries the fingerprints of software designed when most accountants worked on desktop PCs. There are navigation menus, sub-menus, setup wizards and configuration screens that exist because larger organisations need them. A sole trader encountering them for the first time will spend an hour on setup before logging a single transaction.

Pricing in detail: what you actually pay each year

Prices checked August 2026. Sage now sells a dedicated Sage Sole Trader plan at £7 a month excluding VAT (£8.40 including VAT), built around Self Assessment and MTD for Income Tax, and frequently promoted with a deep introductory discount, 90% off for six months at the time of checking. That promo is real, but it ends: budget on the standard rate, which works out at roughly £100 a year including VAT. The fuller Sage Accounting plans, which most comparison content still quotes, sit higher, around £15 a month for Start and £30 a month for Standard on Sage's recent published pricing, roughly £180 to £360 a year; check sage.com for the current figures.

TapTax Starter at £4.99 a month is £59.88 a year, and the free tier files quarterly MTD updates at no cost. So even against Sage's cheapest sole-trader route, TapTax Starter saves you money once Sage's promotional window closes, and against Sage Standard the gap is roughly £300 a year for a sole trader who does not need payroll or purchase orders. TapTax's pricing has no promotional cliffs: Free, Starter or Pro, and the advertised price is the price.

If you want to see what your actual tax bill looks like before choosing any software, the sole trader tax calculator gives you a quick read on your income tax and National Insurance based on your trading profit.

MTD compliance: both pass, but the paths feel very different

Sage Accounting does support MTD for Income Tax. It can submit your quarterly updates and handle the final declaration. On compliance grounds alone, it qualifies.

The experience, however, is meaningfully different. TapTax was designed from the ground up with MTD ITSA as the destination. The quarterly filing is one tap from the main screen. Your bank transactions flow in automatically, the AI categorises them, you confirm anything it is unsure about, and you submit. The quarterly planner logic is baked into how the app thinks about your year.

With Sage, MTD submission is one feature inside a broader accounting system. You get there via the reporting or tax section, and the path assumes you have been maintaining a full set of books. For a sole trader who simply wants to satisfy HMRC and move on, that is a longer walk than necessary.

If you are VAT-registered as well, both products handle VAT returns. But it is worth running your numbers through the VAT calculator first to understand whether VAT registration actually benefits you before you choose a platform with that capability built in.

Ease of use and mobile experience

TapTax is a mobile-first app. It was designed to be used on a phone, on a job site, at a kitchen table, in the time it takes to wait for a client to answer the door. You photograph a receipt, it reads it, categorises it and attaches it to a transaction. The whole interaction takes under a minute.

Sage has mobile apps and they are competent, but the product was architected for a desktop screen with multiple panes visible at once. The mobile experience is functional rather than native. For a sole trader managing finances during the gaps in a working day rather than at a dedicated desk, that matters.

Setup time is also a genuine differentiator. TapTax connects to your bank and starts surfacing categorised transactions almost immediately. Sage's setup involves configuring your chart of accounts, tax settings, business profile and often an opening balance reconciliation. For a sole trader with no bookkeeping background, that is intimidating territory.

Where Sage genuinely wins

This comparison is not a clean sweep. Sage earns its place in certain scenarios.

If you have an accountant who already uses Sage and wants to work inside your books directly, the shared access and familiar interface for that accountant is a real advantage. Many accountancy practices trained on Sage and can navigate it quickly, which means less billable time spent on your books.

If you issue a significant volume of invoices and want your invoicing, expenses and tax all in one place, Sage handles that in a way TapTax deliberately does not. TapTax has no invoicing feature by design, keeping the product focused.

If your business is growing toward taking on staff or a more complex structure, Sage scales in a way a sole-trader-specific tool does not. You would not need to migrate to a new platform.

And if you are already on Sage through a NatWest, RBS or other banking relationship that includes it in a package, the incremental cost to you may be low enough that the switching friction outweighs any saving.

Who should choose which

If you are a plumber or electrician turning over £55,000

You are now above the April 2026 MTD threshold. You need compliant software. You do not need payroll, purchase orders or multi-currency. TapTax Starter at £4.99 a month handles everything HMRC requires, connects to your bank account, and takes minutes a week rather than an afternoon a month. The saving against Sage Standard alone is £25 a month, every month.

If you are a freelance consultant who invoices clients regularly and uses an accountant

This is Sage's stronger ground. If your accountant already works in Sage and you want your invoicing and accounting in one system, the additional cost buys you genuine integration. Your accountant can log in, your invoices match your income records, and year-end is cleaner. TapTax does not compete here.

If you are just starting out as a sole trader and want the cheapest compliant path

TapTax Free or Starter. You are not going to pay £180 to £360 a year to file a tax return when a purpose-built app costs less than a monthly direct debit for a streaming service.

If you are a sole trader who already has Sage through a bank deal

Check your actual contract. If Sage is genuinely free as part of a business banking package, keep it while it costs nothing. If that free period has ended or if you are now paying full price, the comparison above applies in full.

The bottom line

Sage Accounting is not a bad product. It is a good product for the wrong customer. A sole trader buying it independently, paying standard pricing, and using it only to satisfy MTD for Income Tax is paying for a commercial kitchen when they needed a hob.

TapTax is narrower by design. It does not invoice, it does not run payroll, and it does not have a chart of accounts configuration screen. What it does, it does extremely well: it connects to your bank, categorises your transactions using AI, lets you scan receipts on your phone, and files your quarterly MTD updates to HMRC in one tap.

For the vast majority of UK sole traders choosing software in 2026, that is all the product needs to do.
