Key takeaways
- Bridging software remains approved by His Majesty's Revenue and Customs (HMRC) for Making Tax Digital (MTD) for value added tax (VAT), but it does not meet the requirements of MTD for Income Tax Self Assessment (ITSA), which is now live for qualifying sole traders and landlords.
- For clients with straightforward VAT-only obligations and no appetite for system change, bridging software can still serve a purpose in the short term.
- With MTD for ITSA requiring quarterly digital submissions, practices that rely heavily on bridging software face growing operational risk and should plan to move clients to cloud accounting in phases.
- Positioning your practice as an advisory partner through cloud tools like Xero helps you deliver more value, not just compliance.
The compliance landscape for bridging software
Bridging software continues to meet HMRC's requirements for MTD for VAT submissions. For practices with clients who rely on spreadsheets, it remains a compliant route for quarterly VAT returns.
The picture has changed with MTD for ITSA. Since 6 April 2026, sole traders and landlords with qualifying income over £50,000 must keep digital records and submit quarterly updates using HMRC-recognised software. The threshold drops to £30,000 from April 2027 and £20,000 from April 2028.
Bridging software does not support the transaction-level record-keeping, categorised income and expense tracking, or end-of-period statements that MTD for ITSA requires. If any of your clients fall within scope, they need a solution that goes beyond spreadsheet submissions.
Digital link obligations in practice
For clients still using bridging software, the digital link obligation remains the area most likely to create compliance risk. Every figure in the VAT return must trace back to the original source data without manual re-keying, and the responsibility for maintaining those links sits with the practice.
In practical terms, you need to confirm that clients are not copying and pasting figures between workbooks or manually transferring totals. Any break in the digital chain is a compliance risk, and it becomes harder to monitor as client portfolios grow.
Auditing digital link integrity across a portfolio of bridging software clients takes time. If you're managing more than a handful of clients on bridging tools, consider whether the compliance overhead justifies the approach compared to moving those clients to cloud accounting.
When to recommend bridging software to clients
Not every client needs to move to cloud accounting immediately. Bridging software can still be a reasonable short-term solution for certain client profiles, but it is worth being deliberate about who stays on it and for how long.
Clients where bridging software may still suit
Some clients have genuinely simple tax obligations. If a client is VAT-registered but below the MTD for ITSA income thresholds, has no plans to grow, and is resistant to changing systems, bridging software keeps them compliant with minimal disruption.
This typically applies to small sole traders with turnover well under £50,000, businesses winding down, or clients who are approaching retirement and have no interest in adopting new technology.
Clients who should move to cloud accounting
Any client who falls within scope of MTD for ITSA needs more than bridging software can offer. The decision trigger is straightforward: if a client's qualifying income exceeds the current threshold, or is likely to in the next two years, they should be on your priority list for cloud accounting.
Beyond regulatory scope, look at operational signals. Clients who are growing, managing multiple income streams, or asking for more frequent financial reporting will benefit from the automation and real-time visibility that cloud accounting provides.
Bridging software vs cloud accounting software
The choice between bridging software and cloud accounting shapes the kind of service you can deliver and the efficiency of your practice.
Compliance coverage
Bridging software handles MTD for VAT submissions. Cloud accounting software covers MTD for VAT, MTD for ITSA, and positions clients for future regulatory changes without needing a system switch.
Record-keeping
With bridging software, records stay in spreadsheets. You are reliant on clients maintaining them accurately and preserving digital links. Cloud accounting centralises records, automates bank feeds, and reduces the risk of manual errors or broken audit trails.
Practice efficiency
Bridging software requires you to manage each client's spreadsheets individually. There is no portfolio-level visibility, no automated reconciliation, and limited scope for standardising workflows across your client base.
Cloud accounting allows you to standardise processes, manage multiple clients from a single dashboard, and automate repetitive tasks. This frees up time for higher-value advisory work.
Client advisory potential
Bridging software gives you a snapshot at submission time. Cloud accounting gives you continuous access to up-to-date financial data, which means you can advise clients proactively rather than reactively.
Limitations of bridging software
Bridging software was designed to solve a specific problem: getting spreadsheet data into HMRC's MTD for VAT system. As the regulatory landscape evolves, those limitations become more pronounced.
The practical impact for your practice is that you will need to maintain two separate software workflows if some clients remain on bridging tools while others move to cloud accounting. This split adds complexity to your practice operations and increases the risk of compliance errors, particularly around digital record-keeping obligations.
Beyond compliance, bridging software offers no automation. Bank feeds, invoice matching, receipt capture, and real-time reporting are all absent. Every process that cloud accounting handles automatically becomes a manual task when you are working with spreadsheets and bridging tools.
There is also the scalability question. Managing five clients on bridging software is manageable. Managing 50 is a significant operational burden, particularly when each client's spreadsheet setup is slightly different. The lack of standardisation makes it harder to delegate work within your practice or to onboard new team members efficiently.
How to manage clients using bridging software
If you have clients currently on bridging software, a structured approach helps you maintain compliance while building a clear path toward cloud accounting.
1. Assess your current client portfolio
Start by reviewing which clients use bridging software and why. For each one, note their VAT status, income level, business complexity, and whether they fall within scope of MTD for ITSA now or in future phases.
This gives you a clear picture of which clients can stay on bridging software for now and which need to move as a priority.
2. Set up consistent workflows
For clients remaining on bridging software, standardise your processes. Define a template spreadsheet structure, document how digital links are maintained, and establish a review checklist before each submission.
Consistency reduces the risk of errors and makes it easier to spot issues before they reach HMRC.
3. Maintain compliance across your client base
Keep a record of each client's submission history, software version, and any HMRC correspondence. Monitor for changes to HMRC's approved software list to ensure the bridging tool you use remains compliant.
For clients approaching the MTD for ITSA thresholds, check the HMRC ITSA-compatible software list to understand what options are available.
4. Plan how to move clients to cloud accounting in phases
Rather than moving everyone at once, prioritise clients by urgency. Those already in scope for MTD for ITSA come first. Next, target growing businesses that would benefit from real-time data and automation.
Tools like Xero's data capture with Hubdoc can ease the transition by automating receipt and invoice collection, reducing the manual data entry that clients often associate with switching systems.
Frame the move as an upgrade, not a disruption. Clients are more receptive when they understand the practical benefits: less manual work, fewer errors, and better visibility of their financial position.

FAQs on MTD bridging software
Here are some frequently asked questions about MTD bridging software and how it fits into your practice.
Is bridging software still compliant for MTD for VAT?
Yes. Bridging software remains on HMRC's approved list for MTD for VAT submissions. As long as the software maintains compliant digital links and submits returns via the MTD API, it meets the current requirements.
Will bridging software work for MTD for Income Tax?
No. MTD for ITSA requires quarterly transaction-level reporting, categorised records, and end-of-period statements. Bridging software was designed to submit VAT totals from spreadsheets and does not support these requirements. Clients in scope for MTD for ITSA need HMRC-recognised software that handles digital record-keeping natively.
What are the pros and cons of bridging software?
The main advantage is minimal disruption: clients keep their spreadsheets, and submissions are handled through a lightweight tool. The downsides include no automation, no real-time data, no support for MTD for ITSA, and a higher risk of broken digital links as complexity increases.
What are HMRC's digital link requirements?
HMRC requires an unbroken digital trail from source data to the submitted return. No manual re-keying or copy-pasting is allowed between systems. Bridging software satisfies this for VAT by reading directly from spreadsheets, but the practice is responsible for ensuring digital links are preserved throughout the record-keeping process.
Do I need bridging software if my clients use Xero?
No. Xero is HMRC-recognised for both MTD for VAT and MTD for ITSA. It handles digital record-keeping, submissions, and reporting natively, so there is no need for a separate bridging tool. Quarterly updates for MTD for ITSA are due by the 7th of the month following the quarter end, and Xero supports this workflow directly.
How do I help clients move from bridging software to cloud accounting?
Start with the clients who are most at risk: those in scope for MTD for ITSA or those whose businesses have outgrown spreadsheet-based record-keeping. Present the move as a practical improvement, focusing on reduced manual work, fewer compliance risks, and better financial visibility. A phased approach, starting with bank feeds and automated data capture, helps ease the transition without overwhelming the client.
