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 is the lowest entry price among Xero, QuickBooks, Sage, and FreeAgent at standard pricing. It includes MTD for Income Tax submission, bank feeds, Hubdoc receipt capture, 10 invoices a month, and basic cashflow reporting. 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 with formal certification. Accountant familiarity often matters more in practice than the headline price of the software, and Xero wins on that dimension among the major players.

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, Ignite, Grow, Comprehensive, Ultimate). Each tier adds capability rather than swapping you to a different product. If you start on Simple at £7 plus VAT a month and later need VAT (Ignite at £16 plus VAT), payroll (Grow at £33 plus VAT), or multi-currency (Comprehensive at £47 plus VAT), the upgrade is in place with no migration step. This matters for users planning to grow into VAT registration or anticipating adding payroll within the next year or two.
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 £19 plus VAT a month for sole traders and £29 plus VAT a month for limited companies, but 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, which means a sole trader who needs a business account anyway can pair Mettle with free FreeAgent at zero ongoing cost. No other major UK MTD product matches this.
The "I am a landlord with jointly owned properties" problem
FreeAgent for Landlords is the unincorporated landlord version of the product, with 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. For MTD purposes, each joint owner submits their own quarterly updates from within the shared account. 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 (per AccountingCompare's April 2026 review). 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 (a legal requirement for limited companies, and a sensible separation for sole traders), 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. Xero's multi-business feature (available from Standard plan upward) handles this within a single subscription.
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.
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. This is small operationally but worth knowing.
Smart Capture Cap
Receipt OCR is free for up to 10 files a month. Beyond that, an add-on subscription applies. 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: £228 plus VAT a year (year two onward).
Switching to NatWest or Mettle for free FreeAgent: Free, but switching banks adds operational friction. The £84 plus VAT saving over Xero is real but small for a single freelancer.
Verdict: Xero Simple. The switching cost outweighs the saving.
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 standard: £0. Mettle is free and acts as both his business bank and his free 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. 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 FreeAgent's landlord-specific 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: Mettle is essentially FreeAgent with a bank attached
Mettle has no monthly fee, no minimum balance, and the FreeAgent subscription is included for any account making at least one transaction a month. For a sole trader who genuinely wants the cheapest possible MTD path, Mettle plus free FreeAgent costs nothing to operate. Xero has no equivalent route. Xero Simple at £7 plus VAT a month is its floor.
Observation 2: The limited company opt-out does not exist
If you are a limited company director or LLP partner and you switch 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: FreeAgent's landlord ownership-split tooling is more flexible than Xero's tracking categories
Xero handles multi-property landlords through tracking categories, a workable but generic approach designed for any business needing segmented reporting. FreeAgent for Landlords includes ownership splits set at the individual property level, with FreeAgent automatically allocating income and expenses by ownership ratio for each property. For joint-owner landlords (the most common pattern for buy-to-let), this is the difference between manual share calculations and automatic ones. Neither tool replaces a dedicated landlord platform for portfolio analytics, but for joint-ownership MTD compliance specifically, FreeAgent's tooling is the more purpose-built of the two.

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 two caveats (no opt-out from tailored insights for limited companies, and the offer being commercial rather than contractual) are real but proportionate to a £228 to £396 plus VAT annual saving over Xero's mid-tier plans.
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.
