Why This Is A Different Decision Than Most Software Comparisons
Most comparisons between Xero and FreeAgent treat them as two cloud accounting platforms competing on features. They are, but in 2026 the more honest framing is that they are competing on price route. Xero is the cheapest standard-priced route to MTD ITSA from any major UK provider, at £7 plus VAT a month for Xero Simple. FreeAgent is the only major UK MTD ITSA product that is genuinely free, but only if you hold a business current account with NatWest, Royal Bank of Scotland, Ulster Bank, or Mettle (NatWest's free digital business banking brand).
That difference matters because the decision is not "which product has better features" in the abstract. Both are HMRC-recognised. Both submit quarterly updates and the Final Declaration directly to HMRC. The genuine decision is whether your banking arrangement (or willingness to change it) unlocks the free route, and whether the operational trade-offs of switching banks justify the saving. This article is structured around that decision.
What Problems Does Xero Solve For MTD?
Xero is the most-used cloud accounting platform in the UK among accountancy practices (per MTD.digital's March 2026 software comparison), and offers the same MTD ITSA capability on every plan from Simple upward. Here is what it solves.
The "I want the cheapest standard-priced MTD route from a major provider" problem
Xero Simple sits at £7 plus VAT a month, which Xero confirmed as unchanged in its September 2025 pricing update. It is HMRC-recognised for MTD for Income Tax, includes bank feeds, Hubdoc receipt capture, up to 10 invoices a month, and basic cashflow reporting (per Xero's partner product page, May 2026). For a sole trader or single-property landlord who does not bank with NatWest Group, this is the cheapest practical major-provider route to MTD compliance with no banking conditions attached.
The "I do not want my software tied to my bank" problem
Xero is bank-agnostic. Its bank feeds connect to most UK business accounts through Open Banking, and the subscription is paid directly to Xero. There is no commercial dependency on a particular bank, no risk that a change in banking arrangements affects software access, and no requirement to keep an account open beyond your own business needs. For business owners who value separation between banking provider and software provider, this matters.
The "my accountant already uses Xero" problem
Xero is the largest cloud platform in the UK accountant ecosystem. If your accountant already runs other clients on Xero, sharing access is a one-click invite, and they can review records and submit MTD updates on your behalf. The Xero Gold Partner network covers thousands of UK practices. Accountant familiarity often matters more in practice than the headline price of the software, and Xero wins on that dimension among the major players.
The "I want one product across all my plans, not a fork" problem
Xero offers a single product across five plan tiers: Simple at £7 plus VAT a month, Ignite at £16, Grow at £37, Comprehensive at £50, and Ultimate at £65 (per Xero's published price updates, effective September 2025 and unchanged through May 2026). Each tier adds capability rather than swapping you to a different product. If you start on Simple and later need VAT (Ignite), payroll (Grow), or multi-currency (Comprehensive), the upgrade is in place with no migration step.
What Problems Does FreeAgent Solve For MTD?
FreeAgent has been owned by NatWest Group since 2018, and its pricing model reflects that. Standard pricing is now tiered by business type, at £10 plus VAT a month for landlords, £19 for sole traders, £24 for partnerships and LLPs, and £29 for limited companies (per Payroll Prices, January 2026, and FreeAgent's pricing page, May 2026). The same product is free for as long as you hold an eligible NatWest Group business current account. Here is what it solves.
The "I want completely free HMRC-recognised MTD software from a major provider" problem
This is FreeAgent's defining problem-solved, and the reason this article exists. If you hold a business current account with NatWest, Royal Bank of Scotland, Ulster Bank, or Mettle, FreeAgent is included at no cost for as long as you retain the account. This is not a trial. It is the full product: MTD for Income Tax submissions, MTD for VAT, Self Assessment filing, invoicing, expense tracking, bank feeds, and payroll. Mettle is free to open with no monthly fee and no minimum balance, with one transaction a month required to keep the FreeAgent subscription active (per NatWest's published FreeAgent terms, April 2026). No other major UK MTD product matches this.
The "I am a landlord with jointly owned properties" problem
FreeAgent for Landlords is the dedicated unincorporated-landlord plan at £10 plus VAT a month (or free through the NatWest Group route). It includes native per-property profit and loss reporting and ownership splits set at the individual property level. Joint owners (the most common pattern for UK buy-to-let) can operate under a single FreeAgent licence: ownership ratios are configured per property, and FreeAgent automatically allocates income and expenses by share. Xero handles property income through tracking categories, which works but requires manual setup and manual share calculations for joint-owned properties.
The "I want Self Assessment filing baked in, not bolted on" problem
FreeAgent's Self Assessment filing wizard is one of the best regarded in the UK market for sole traders and landlords. It auto-populates the UK Property (SA105) pages where possible and submits directly to HMRC from within the software. This is included on every FreeAgent route, including the free version. Xero Simple supports Final Declaration filing for MTD purposes but does not match FreeAgent's depth of SA wizard tooling for landlords with property income.
The "I am opening a new business account anyway" problem
If you are a sole trader or landlord who needs a business bank account in the first place, Mettle pairs free banking with free FreeAgent. The pairing turns a piece of necessary admin into a free software subscription. No equivalent route exists for Xero, QuickBooks, or Sage.
What Problems Does Each One Miss?
Both products are competent for MTD ITSA. Neither is perfect for every situation, and the honest gaps matter.
Where Xero Misses
Free Tier
Xero has no permanent free plan for MTD ITSA. The 30-day trial converts to paid, with £7 plus VAT a month as the floor. For users who genuinely want zero ongoing cost and can meet FreeAgent's banking condition, Xero cannot match it on price.
Joint-Ownership Splits
Xero handles multi-property landlords through tracking categories, which work but require manual share calculations for joint-owned properties. For a husband-and-wife buy-to-let, this means doing the maths on every transaction or running periodic share reports manually. FreeAgent's ownership-split tooling automates it.
Invoice Cap On Simple
The £7 plan caps you at 10 invoices a month. Most sole traders and single-property landlords sit comfortably under this, but anyone billing 11 or more clients monthly needs Ignite at £16 plus VAT a month, which closes the gap with FreeAgent's standard price.
Where FreeAgent Misses
Multiple Businesses In One Account
FreeAgent requires a separate account per business. A sole trader who also has rental income needs two FreeAgent accounts: one as a sole trader, one as an unincorporated landlord. Each can submit MTD updates independently, but cross-account tax estimates are calculated in sequence rather than combined.
Banking Lock-In For The Free Route
FreeAgent is free only as long as you retain an eligible NatWest Group business current account. If you switch banks for any reason (better rates elsewhere, business sale, account closure), FreeAgent reverts to its standard price. This is operationally low-risk (NatWest has maintained the offer since 2018) but it is a commercial arrangement, not a contractual right.
Mettle Activity Requirement
Mettle accounts must make at least one transaction a month to keep FreeAgent active. If you go a month with no activity (a long project gap, a holiday, no incoming payments), FreeAgent suspends until you reinstate it (per Business Expert's NatWest review, April 2026). If your quarterly submission falls in that gap, you are filing manually.
Limited Company Opt-Out Absent
Limited company directors and LLP partners who switch to NatWest-Group-funded FreeAgent agree to receive "tailored insights" from "trusted partners" inside the product, with no opt-out (per FreeAgent's Terms of Service). Sole traders and partnerships can opt out.
Smart Capture Cap
Receipt OCR is free for up to 10 files a month. Beyond that, the Smart Capture Unlimited add-on applies at extra cost. Xero's Hubdoc is included on Simple with no per-file cap.
Three Pricing Profiles
These profiles surface the specific trade-off this article exists to address: banking choice versus software choice. They are different from the £55k freelancer, £52k single-property landlord, and £57k hybrid landlord profiles used in Xero vs QuickBooks for MTD and Xero vs Sage for MTD.
Profile A: Sarah, freelance designer with HSBC business banking, £58,000 a year
Sarah is in MTD scope from April 2026. She has banked with HSBC since launching her business and has no compelling reason to switch. Her invoice volume is around 8 a month.
Xero Simple: £84 plus VAT a year. Well within her invoice limit.
FreeAgent standard (sole trader): £228 plus VAT a year from month 7 onward, with 50% off for the first six months (effectively £171 plus VAT in year one).
Switching to NatWest or Mettle for free FreeAgent: Free, but switching banks adds operational friction.
Verdict: Xero Simple. The switching cost outweighs the £144 plus VAT annual saving over standard FreeAgent. Compared to Xero Simple, free FreeAgent saves £84 plus VAT a year, which is real but modest for a single freelancer with established banking.
Profile B: Daniel, sole trader plumber opening his first business bank account, £62,000 a year
Daniel currently uses a personal account for business income (against most banks' terms of service) and needs a proper business account anyway. Mettle is free, takes minutes to open, and includes FreeAgent at no cost.
Xero Simple: £84 plus VAT a year. He would still need to open a business account separately.
FreeAgent via Mettle: £0. Mettle is free and acts as both his business bank and his FreeAgent subscription.
Verdict: Mettle plus free FreeAgent. Daniel needs a business account anyway, and the Mettle route turns necessary admin into a free MTD subscription. Annual saving over Xero Simple: £84 plus VAT.
Profile C: Priya, landlord with 3 properties and a NatWest business account, £54,000 rental income yearly
Priya is in MTD scope from April 2026 and has been using a spreadsheet. She already banks with NatWest.
Xero Simple: £84 plus VAT a year. Property income tracked using tracking categories rather than native property fields, requiring manual setup.
FreeAgent for Landlords via NatWest: £0 (versus standard £120 plus VAT a year for the dedicated landlord plan). Includes native per-property profit and loss, joint-ownership splits, and unlimited properties on a single account.
Verdict: Free FreeAgent for Landlords. Priya already meets the banking condition with no switching required, and the dedicated landlord tooling means less manual setup than Xero's tracking categories. Annual saving over Xero Simple: £84 plus VAT, plus reduced setup time.
Honest Caveat Shared Across All Three Profiles
Neither Xero Simple nor FreeAgent is purpose-built for landlords with portfolio-level investment analytics (yields, loan-to-value, arrears tracking). RentalBux, Hammock, Landlord Vision, and Landlord Studio cover that gap. The choice in this article is "which major-player accounting tool" 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: FreeAgent's pricing tiers by business type, not by feature
Unlike most accounting platforms, where the higher you pay the more features you get, FreeAgent's tiers are differentiated by business type rather than capability. The landlord plan at £10 lacks payroll (which landlords do not need) but adds native property reporting. The limited company plan at £29 includes corporation tax filing. The sole trader plan at £19 sits in the middle. A landlord on FreeAgent is paying less for a more property-specialised version of the same product, which is unusual in the market.
Observation 2: The limited company opt-out does not exist
If you are a limited company director or LLP partner switching to NatWest-Group-funded FreeAgent, you agree to receive "tailored insights" from "trusted partners" inside the product, with no opt-out. This is in FreeAgent's published Terms of Service. Sole traders and partnerships can opt out. The free route is still genuinely free, but limited company users should have this information before switching.
Observation 3: Mettle's "one transaction a month" rule has real operational consequences
Most reviews of the Mettle plus FreeAgent route describe it as fully free with no strings attached. The strings exist. If a month passes with no transactions on the Mettle account (a quiet month, a long client gap, a holiday), FreeAgent suspends until the account is reactivated (per Business Expert's NatWest review, April 2026). For sole traders with irregular income, this can mean filing manually for a quarter where Mettle went dormant. The common workaround is to run a £1 standing order through the Mettle account each month.

Where Each Genuinely Wins
Xero wins for:
Anyone who does not bank with the NatWest Group and does not want to switch.
Sole traders who need the simplest possible HMRC-recognised MTD product at the lowest standard price.
Businesses planning to grow into VAT, payroll, or multi-currency. Xero's upgrade path is one of the most coherent in the UK market.
Users whose accountant works primarily in Xero. Accountant familiarity often matters more than headline price.
FreeAgent wins for:
Anyone already banking with NatWest, RBS, Ulster Bank, or Mettle. The free route is a clear value advantage no major-player competitor matches.
Sole traders opening a new business bank account. The Mettle plus free FreeAgent pairing turns necessary admin into a free MTD subscription.
Unincorporated landlords with joint-owned properties. Native ownership-split tooling is more practical than Xero's tracking categories for that specific use case.
Users who value Self Assessment filing built into the same tool. FreeAgent's SA wizard is well regarded across UK reviews.
Conclusion
The honest answer to "Xero or FreeAgent for MTD?" depends on something most software comparisons treat as a footnote: your business bank. If you bank with NatWest, RBS, Ulster Bank, or Mettle, or are willing to switch, FreeAgent is the better deal. Free, full-featured, HMRC-recognised, with practical advantages for landlords through native per-property reporting and ownership splits. The caveats (no opt-out from tailored insights for limited companies, the Mettle activity requirement, the offer being commercial rather than contractual) are real but proportionate to a £120 to £348 plus VAT annual saving over standard FreeAgent pricing.
If you do not bank with the NatWest Group and switching is not on the table, Xero Simple at £7 plus VAT a month is the better practical choice. It is the cheapest standard-route MTD product from any major UK provider, available to anyone, with a coherent upgrade path if your business grows into VAT or payroll. The 10-invoice cap is a real constraint, but for most sole traders and single-property landlords it is well above the monthly transaction count.
Neither is the right answer for landlords needing portfolio-level investment analytics. That is a different decision, addressed elsewhere in our content. For straightforward MTD compliance among the major UK accounting platforms, this comparison is, unusually, a comparison of pricing routes more than of products.
