Which MTD software is best for accountants managing multiple clients?

For accountants and agents managing multiple MTD clients, Xero and QuickBooks Online both offer dedicated practice management platforms (Xero HQ and QuickBooks ProAdvisor/Online Accountant) with multi-client dashboards, bulk client management, and team-based access controls. FreeAgent also has an agent portal but with more limited multi-client workflow tools. Sage's Accountant Edition provides strong integration with Sage's broader ecosystem for practices already using Sage tools. The right choice depends on your practice size, existing software stack, and client mix.

Does HMRC MTD software need to be on an approved list?

Yes — per HMRC's published guidance, any software used to meet MTD obligations (for VAT or Income Tax) must appear on HMRC's approved software list on GOV.UK. Software must support digital record-keeping, digital linking between components, and API submission of quarterly updates and Final Declarations directly to HMRC. Using software not on the approved list will not meet your MTD obligations.

MTD software FAQs

Common questions — agents & accountants.

Which MTD software is best for accountants managing many clients?

For large-scale practice management, Xero (Xero HQ) offers the most comprehensive multi-client dashboard, granular staff access controls, and integration with Xero Practice Manager. QuickBooks Online Accountant is the free alternative for QBO-using practices and has strong client collaboration tools. HMRC's approved software list on GOV.UK confirms all four major providers are HMRC-recognised.

Does HMRC provide its own software for agents?

HMRC provides free tools on GOV.UK for basic MTD filing but these are not a substitute for practice management software. Per HMRC's guidance, agents should use HMRC-recognised software from the approved list to meet clients' MTD obligations at scale. HMRC's Agent Services Account (ASA) is the mechanism through which agents are authorised to file on behalf of clients.

What is digital linking and why does it matter for agents?

Per HMRC's MTD guidance, digital linking means data must flow between software components electronically without manual re-entry. For agents, this means if a client uses a separate data capture tool (e.g., receipt scanning app), the data must be digitally linked to the bookkeeping software and then to the MTD submission. Copy-pasting between systems without a digital link does not comply with MTD requirements.

Can agents submit MTD quarterly updates on behalf of clients?

Yes — per HMRC's published guidance, authorised agents can submit MTD quarterly updates and Final Declarations on behalf of clients through the Agent Services Account (ASA). The agent must be properly authorised under HMRC's agent authorisation rules. All major MTD software platforms support agent authorisation through ASA integration.

How does the agent services account (ASA) work for MTD?

The HMRC Agent Services Account (ASA) is the portal through which agents manage their MTD client relationships. Agents register their practice on ASA, then clients grant authorisation (replacing the old 64-8 paper authorisation for MTD). The ASA links to your MTD software via the HMRC API, allowing you to view client obligations, submit updates, and access MTD filing history. See HMRC's ASA guidance on GOV.UK.

Which software has the best Self Assessment integration for agents?

FreeAgent is widely regarded as having the most integrated Self Assessment and MTD ITSA workflow specifically for sole traders and landlords — its SA filing wizard auto-populates SA103 and SA105 forms from the same bookkeeping data. Xero handles the MTD ITSA workflow comprehensively across all plans. QuickBooks Sole Trader includes SA103 generation. For agents advising clients on sole trader bookkeeping, FreeAgent's SA depth is a genuine differentiator.
