Why This Comparison Is Really A Pricing Decision
Most comparisons between QuickBooks and Sage treat them as two general accounting platforms with overlapping features. For limited companies that is broadly fair. For sole traders facing MTD for Income Tax from April 2026, it is not. Both providers have built entry-tier products specifically aimed at the same audience (non-VAT-registered sole traders who need MTD compliance without paying full accounting prices), and the genuine decision is which of those entry products gives you the cheapest legitimate path to HMRC compliance with the trade-offs you can actually live with.
QuickBooks Sole Trader is on a 90% off promotional offer at £1 plus VAT a month for the first six months, then £10 plus VAT a month at standard pricing (per Intuit's UK pricing page, May 2026). Sage Sole Trader Free is permanently free with a 5 invoice a month cap and 25 AI-categorised transactions a month cap (per Startups.co.uk's March 2026 Sage review and TechRadar Pro's April 2026 free MTD software roundup). Sage Sole Trader is £7 plus VAT a month with three months free (per Sage UK's Self Assessment Software page, May 2026). All three are HMRC-recognised. The decision is not which one has more features in absolute terms. It is which one's feature gap matches what you can live without.
What Problems Does QuickBooks Sole Trader Solve For MTD?
QuickBooks Sole Trader was launched in November 2024 specifically for the £20,000 to £100,000 UK sole-trader market preparing for MTD ITSA. It is the budget tier within QuickBooks Online, sitting below Simple Start (£16 plus VAT a month) and Essentials (£33 plus VAT a month). Here is what it solves.
The "I want one paid plan that handles everything a sole trader needs" problem
QuickBooks Sole Trader covers the full MTD ITSA workflow: digital record-keeping for sole-trade and UK property income, four quarterly updates a year submitted by the 7th of the month after each quarter end, and the Final Declaration replacing the old Self Assessment return. It also includes invoicing, bank feeds for one business bank account, mileage tracking through the QuickBooks mobile app, receipt capture, and a year-to-date Self Assessment tax estimate. For sole traders who want one tool that does record-keeping plus invoicing plus tax estimation, this is the cheapest QuickBooks plan that delivers it.
The "I want to lock in 90% off for six months" problem
QuickBooks UK is currently running a 90% off promotional offer at £1 plus VAT a month for the first six months on Sole Trader, then £10 plus VAT a month thereafter (per Intuit's UK pricing page and Startups.co.uk's March 2026 review). For a sole trader who values the lowest possible introductory rate from a major provider, no other platform matches this entry price. Sage Sole Trader paid is £0 for three months, then £7, which is cheaper from month four onward but more expensive in months one to three on a like-for-like basis.
The "I have a single rental property and want one tool, not two" problem
QuickBooks Sole Trader supports landlords with a single property income alongside sole-trader income (per Intuit's UK product page, May 2026). UK property and self-employment are treated as separate income streams within the same account, and quarterly updates can be submitted for each. For a sole trader with one buy-to-let plus a small consultancy business, this avoids running two separate subscriptions.
The "I want to file directly to HMRC without bridging software" problem
QuickBooks Sole Trader submits quarterly updates and the Final Declaration directly to HMRC through Intuit's MTD integration, with no separate portal step and no bridging software. After all four quarters are submitted, the Final Declaration replaces the traditional Self Assessment return.
What Problems Does Sage Solve For MTD?
Sage took a bifurcated approach to the sole-trader market: a permanently free tier for the simplest cases, and a £7 paid tier for users who need more capability. Both are MTD-ready. Here is what each solves.
The "I want completely free HMRC-recognised MTD software with no banking conditions" problem
Sage Sole Trader Free is permanently free with no time limit, no card required, and no banking condition (per Sage UK's Self Assessment Software product page and TechRadar Pro's April 2026 free MTD software roundup). It is HMRC-recognised for MTD ITSA, supports digital record-keeping for sole-trader income, generates a completed SA103 Self Assessment form, and includes basic bank feed connectivity. The free tier has explicit caps of 5 sales invoices a month and 25 AI-categorised transactions a month (per Startups.co.uk's March 2026 Sage review). For non-VAT-registered sole traders with simple invoicing patterns and modest transaction volumes, this is one of the few genuinely free MTD ITSA routes from a major UK provider with no banking strings attached, unlike FreeAgent (free only with NatWest Group banking).
The "I want a paid sole-trader plan cheaper than QuickBooks at standard pricing" problem
Sage Sole Trader at £7 plus VAT a month sits below QuickBooks Sole Trader at the standard £10 plus VAT a month price point (per Sage UK and Intuit UK pricing pages, May 2026). It adds unlimited sales invoices, AI-powered expense auto-categorisation with no transaction cap, snap-and-scan receipt records, connection to up to 10 bank accounts, and chat-only customer service from 8am to 8pm Monday to Friday (per Sage UK's product page). The three-months-free introductory offer effectively makes the first year cost £63 plus VAT, compared to £66 plus VAT for QuickBooks Sole Trader's introductory period (£1 for six months, then £10 for six months).
The "I am also doing CIS work" problem
Sage Sole Trader (paid) is scheduled to add CIS (Construction Industry Scheme) features for subcontractors, with the rollout anticipated during 2026 (per Sage Community Hub's CIS thread, April 2026). CIS handling is not yet live on Sole Trader Paid as of mid-May 2026 but is confirmed for inclusion at no additional cost when it launches. QuickBooks Sole Trader does not include CIS deduction management at the same price tier. CIS functionality on QuickBooks sits in Simple Start (£16 plus VAT a month) and above (per Intuit UK's product FAQ).
The "my accountant uses Sage" problem
Sage has a large UK accountant network, including Sage for Accountants and the Sage MTD Agent tool used by more than 14,000 UK accounting firms (per Sage's accountant ecosystem pages). If your accountant already runs other clients on Sage, sharing access through Sage for Accountants is built into the platform. QuickBooks also has a strong UK accountant network through its ProAdvisor programme, but in the sole-trader segment specifically, Sage's accountant integration has historically been stronger.
What Problems Does Each One Miss?
Both products are competent at their price point. Neither is perfect for every situation.
What QuickBooks Sole Trader Misses
No free tier: QuickBooks offers a 30-day free trial that converts to paid, with £1 plus VAT a month as the promotional floor and £10 plus VAT a month standard. For sole traders who want zero ongoing cost, QuickBooks cannot match Sage Sole Trader Free.
Intuit Assist not included: Intuit's own pricing page explicitly states: "Intuit Assist features may differ based on product. Not available with QuickBooks Sole Trader or QuickBooks Self-Employed." Full Intuit Assist AI is available from Simple Start (£16 plus VAT a month) upward. AI tooling on the Sole Trader tier is therefore more limited than the headline product positioning suggests.
VAT: QuickBooks Sole Trader does not include MTD for VAT. VAT-registered sole traders need to step up to QuickBooks Simple Start at £16 plus VAT a month. Sage Sole Trader also excludes VAT (Sage Accounting Start at £18 plus VAT a month covers it), so this is a shared limitation, but it matters for sole traders approaching the £90,000 VAT threshold.
Multiple properties: QuickBooks Sole Trader supports a single property income alongside sole-trader work. Landlords with multiple properties need to step up to QuickBooks Simple Start or above.
CIS not at this tier: CIS handling sits in QuickBooks Simple Start and above per Intuit's own product FAQ.
What Sage Sole Trader Free Misses
5 invoice a month cap: Sage Sole Trader Free caps invoicing at 5 sales invoices a month. Sole traders billing more than 5 clients monthly need to upgrade to Sage Sole Trader at £7 plus VAT a month or use a separate invoicing tool. This is the single most significant constraint on the free tier and the reason many sole traders move to the paid Sage tier rather than staying on Free.
25 AI-categorised transactions a month cap: AI-powered transaction categorisation is included on the free tier but capped at 25 transactions a month. Beyond that, categorisation is manual. For a sole trader with simple income patterns, this is enough. For higher transaction volumes, the paid tier removes the cap.
No property income: Sage Sole Trader Free is for non-VAT-registered sole-trader income only. It does not handle UK property income. Landlords need the paid Sage Sole Trader plan or different products entirely.
Limited bank accounts: Free tier connects to a smaller number of bank accounts than the paid tier, which supports up to 10.
Where Sage Sole Trader (paid) Misses
Newer to the sole-trader market. Sage rebranded its Sage Individual product to Sage Sole Trader during 2025 and is still rolling out features (CIS pending as of mid-May 2026). The product is functional, but QuickBooks has a longer track record in the sole-trader segment.
Property income coverage. Sage Sole Trader supports UK property income for unincorporated landlords, but the landlord-specific tooling (joint-ownership splits, per-property reporting) is less developed than in landlord-purposed tools like FreeAgent for Landlords. QuickBooks Sole Trader's property income handling is broadly comparable, with manual tagging for multi-property reporting.
Three Pricing Profiles
These profiles surface the trade-offs this article exists to address: when "free" is genuinely free, and when "cheap" beats it once admin time is counted.
Profile A: Mia, freelance copywriter with two long-term retainer clients, £52,000 yearly
Mia invoices two clients a month on the same recurring schedule. Her expenses are simple (laptop, software subscriptions, occasional travel) with maybe 15 to 20 transactions a month. She has no rental income and no VAT registration.
QuickBooks Sole Trader: £66 plus VAT in year one, £120 plus VAT a year thereafter.
Sage Sole Trader (paid): £63 plus VAT in year one, £84 plus VAT a year thereafter.
Sage Sole Trader Free: £0. Her 2 invoices a month fits comfortably within the 5-invoice cap, and her 15 to 20 transactions a month fits within the 25 AI categorisation cap.
Verdict: Sage Sole Trader Free. Mia is the textbook user the free tier is designed for. Both caps comfortably absorb her actual usage, and the annual saving over the cheapest paid option (Sage Sole Trader at £84 plus VAT a year) is the highest-value choice for her pattern.
Profile B: Tom, electrician in Birmingham, £61,000 a year
Mia invoices two clients a month on the same recurring schedule. Her expenses are simple (laptop, software subscriptions, occasional travel) with maybe 15 to 20 transactions a month. She has no rental income and no VAT registration.
QuickBooks Sole Trader: £66 plus VAT in year one, £120 plus VAT a year thereafter.
Sage Sole Trader (paid): £63 plus VAT in year one, £84 plus VAT a year thereafter.
Sage Sole Trader Free: £0. Her 2 invoices a month fits comfortably within the 5-invoice cap, and her 15 to 20 transactions a month fits within the 25 AI categorisation cap.
Verdict: Sage Sole Trader Free. Mia is the textbook user the free tier is designed for. Both caps comfortably absorb her actual usage, and the annual saving over the cheapest paid option (Sage Sole Trader at £84 plus VAT a year) is the highest-value choice for her pattern.
Profile C: Daria, sole-trader with 1 buy-to-let property, £58,000 a year total
Around £43,000 design income and £15,000 rental income. Single property, no joint ownership. She wants one tool, not two.
QuickBooks Sole Trader: £66 plus VAT year one, £120 plus VAT a year thereafter. Supports sole-trader and single-property income in the same account.
Sage Sole Trader (paid): £63 plus VAT year one, £84 plus VAT a year thereafter. Also supports both income types.
Sage Sole Trader Free: Does not support property income. Ruled out for Daria.
Verdict: Sage Sole Trader (paid). Both paid options cover her use case, but Sage is cheaper by £36 plus VAT a year at standard pricing, and the AI categorisation has no monthly cap, which matters for a designer mixing client billing and property expenses. Sage Sole Trader Free is ruled out by the property income requirement.
Honest Caveat Shared Across All Three Profiles
Neither QuickBooks Sole Trader nor either Sage Sole Trader tier is purpose-built for landlords with multiple properties, joint ownership, or portfolio-level analytics. RentalBux, Hammock, Landlord Vision, and Landlord Studio cover that gap. The choice in this article is "which major-player sole-trader tool for MTD" rather than "which best landlord platform."
Three Observations Not On The Marketing Sites
These are findings from working through both platforms' documentation rather than their landing pages.
Observation 1: Sage Sole Trader Free's hidden caps matter more than the headline "free"
Most coverage of Sage Sole Trader Free reports it as "permanently free" without flagging the operational caps. The two that matter most: 5 sales invoices a month and 25 AI-categorised transactions a month (per Startups.co.uk's March 2026 Sage review and TechRadar Pro's April 2026 free MTD software roundup). Both caps are perfectly reasonable for a freelancer with one or two retainer clients. Both are restrictive for a tradesperson, consultant, or anyone with a higher invoice volume. The cap is the difference between "free is genuinely free" and "free with workflow workarounds."
Observation 2: QuickBooks Sole Trader lacks Intuit Assist despite the brand association
QuickBooks markets Intuit Assist as central to its AI proposition. Intuit's own pricing footer says: "Not available with QuickBooks Sole Trader or QuickBooks Self-Employed." Full Intuit Assist sits in Simple Start (£16 plus VAT a month) and above. This is meaningful because most comparison articles assume QuickBooks Sole Trader inherits the parent product's AI capabilities. It does not. Categorisation on Sole Trader is largely rule-based and manual, with AI Agents (the more capable tier) starting at Advanced.
Observation 3: The CIS gap closes during 2026, not from April 2026
Sage announced CIS features for Sage Sole Trader paid from April 2026 at no additional cost. As of late April 2026, Sage's own Community Hub confirmed that the CIS settings were not yet live on Sole Trader Paid, with rollout "anticipated by the end of this month" (April 2026). The functionality is confirmed for inclusion at no additional cost, but anyone choosing the platform for CIS today should verify the feature is live before committing. The Sage roadmap is clear, but the timing of CIS availability has slipped.

Where Each Genuinely Wins
QuickBooks Sole Trader wins for:
Sole traders who prioritise the lowest possible introductory price (£1 plus VAT a month for six months on the current 90% off promotion).
Users whose accountant uses QuickBooks. ProAdvisor familiarity matters at year-end.
Sole traders with a single property income alongside their trade who want one tool that handles both.
Users who value the QuickBooks mobile app, generally regarded as the strongest in the sole-trader market for receipt capture and mileage tracking.
Sage Sole Trader (free) wins for:
Non-VAT-registered sole traders invoicing 5 or fewer clients a month with under 25 transactions a month.
Anyone who wants HMRC compliance with zero ongoing software cost and no banking strings.
Freelancers with one or two retainer clients and simple expense patterns.
Sage Sole Trader (paid) wins for:
Sole traders who want the cheapest paid major-provider plan with unlimited invoicing, uncapped AI categorisation, and bank feeds (£7 plus VAT a month versus QuickBooks at £10 plus VAT a month standard).
Self-employed subcontractors in construction who want CIS at the entry tier when it rolls out.
Users whose accountant is on Sage for Accountants.
Sole traders with a single UK property income who want one tool covering both income streams at the lowest paid price.
Conclusion
The honest answer to "QuickBooks or Sage for MTD?" depends on what you actually need at the entry tier. If you are a non-VAT-registered sole trader with 5 or fewer invoices a month and simple expense patterns, Sage Sole Trader Free is the cheapest legitimate MTD path from any major UK provider with no banking conditions. The trade-offs (5 invoice cap, 25 transaction AI cap, no property income) are real but proportionate.
If you need unlimited invoicing, uncapped AI categorisation, and direct support, the cheapest paid path is Sage Sole Trader at £7 plus VAT a month with three months free. It undercuts QuickBooks Sole Trader by £3 plus VAT a month at standard pricing and includes CIS features when they roll out during 2026. QuickBooks Sole Trader is the stronger product if your accountant is on QuickBooks, if you want the lowest possible introductory price (£1 plus VAT a month for six months under the current 90% off promotion), or if you place high value on QuickBooks' mobile app and mileage tracking. The trade-off is paying £36 plus VAT a year more from year two onward, and accepting that full Intuit Assist is not available at the Sole Trader tier.
Neither is the right answer for landlords needing portfolio-level investment analytics. That is a different decision, addressed elsewhere in our content. For sole traders looking for the cheapest legitimate route through MTD ITSA among the major UK providers, this comparison is, unusually, a decision about how much "free" actually costs you in admin time, and how much "cheap" is worth in year two when the introductory pricing ends.
