Tools That Help Accountants Manage Making Tax Digital for All Clients at Once

Managing Making Tax Digital compliance across an entire client base is one of the defining operational challenges for modern accounting practices. As HMRC's rollout continues to expand, the pressure to stay on top of deadlines, submissions, and client readiness has never been greater.

The good news is that the market for practice-support software has matured considerably. Whether you need a fully integrated compliance hub, a smarter way to collect documents, or simply a better system for booking client calls, there is a tool designed for the job. Here is a look at the options worth knowing.

Sage for Accountants

Sage for Accountants is built from the ground up for practices managing MTD compliance at scale. It gives accountants a centralised dashboard where every client's submission status, upcoming deadlines, and digital record-keeping can be monitored without switching between systems. For practices juggling dozens or hundreds of clients, that single-pane-of-glass view is not a luxury but a genuine necessity.

A Purpose-Built Compliance Engine

The platform connects directly with HMRC's Making Tax Digital gateway, meaning quarterly updates and VAT submissions can be filed on behalf of clients without leaving the software. Sage's bridging tools also mean that clients who are not yet on fully cloud-based bookkeeping can still be brought into compliance without a disruptive overhaul of how they work day to day.

The client management layer is where Sage particularly stands out. Each client profile holds their MTD obligations, filing history, and linked records in one place, making it straightforward for any member of the practice team to pick up where a colleague left off. Permission controls mean clients themselves can access relevant parts of their own data securely.

Built for the Way Practices Actually Work

Sage has invested heavily in making the onboarding experience practical. Practices can bring new clients onto the platform with guided steps, reducing the back-and-forth that typically slows down the transition to digital. The interface is clean enough that clients who interact with it directly rarely need hand-holding from the accountant.

For practices that want one tool to anchor their entire MTD workflow, Sage for Accountants is the natural starting point. Its combination of HMRC recognition, client management depth, and practice-wide visibility makes it the most complete solution in this list.

Liscio

Liscio is a client communication and document-sharing platform designed with accounting firms in mind. Its core strength is creating a secure, branded portal through which clients can upload documents, sign forms, exchange messages, and respond to requests, all without needing to use email or remember login credentials to multiple systems.

Simplifying the Client-Facing Side of MTD

For MTD purposes, where clients need to regularly share records and respond to requests from their accountant, Liscio addresses a real friction point. The mobile-first design means clients can photograph receipts or upload bank statements directly from their phone, which suits sole traders and landlords who are unlikely to be sitting at a desktop when they think to share something.

The task and request tracking within Liscio helps practices stay on top of outstanding items from clients. When a quarterly update is approaching, accountants can send targeted requests and see at a glance who has responded and who still needs a nudge, reducing the manual chasing that tends to dominate this kind of compliance work.

A Strong Fit for Client-Facing Workflows

Liscio does not handle HMRC submissions directly, so it works best as a complement to a dedicated MTD or practice management platform rather than a standalone solution. Practices that already have their compliance infrastructure in place and want to improve the client experience layer will find it a thoughtful addition to their toolkit.

Calendly

Calendly is a scheduling tool that eliminates the back-and-forth involved in booking meetings. Clients are given a link to the accountant's available calendar and can book a slot themselves, with automatic confirmations and reminders sent to both parties.

Reducing Admin Around Client Meetings

In the context of MTD, where onboarding conversations, quarterly review calls, and compliance check-ins are a recurring feature of practice life, having a frictionless way to book time with clients is more valuable than it might initially seem. Calendly integrates with most calendar systems and video-conferencing tools, so meetings can be set up end-to-end without any manual coordination.

The tool supports multiple meeting types, which is useful for practices that offer different appointment formats, such as a short onboarding call versus a longer annual review. Buffer times, limits on daily bookings, and round-robin assignment to team members are all configurable, giving practices a degree of control over how their time is allocated.

Scheduling as a Practice Efficiency Tool

Calendly's role in an MTD toolkit is a narrow but practical one. It does not touch compliance directly, but it removes a layer of administrative friction that, across a large client base, can quietly consume a significant amount of staff time. Used alongside a more comprehensive practice platform, it contributes to a smoother overall client experience.

Dropbox Business or SharePoint

Dropbox Business and Microsoft SharePoint are cloud storage and collaboration platforms that give practices a secure place to store, organise, and share files with clients and colleagues. Both are well-established, widely trusted, and capable of handling large volumes of documents.

Document Management at Practice Scale

For MTD compliance, having organised, accessible digital records is a baseline requirement. Whether that means storing source documents, signed engagement letters, or exported reports from accounting software, both Dropbox Business and SharePoint provide the infrastructure to keep files tidy and retrievable. SharePoint's deeper integration with the Microsoft 365 ecosystem makes it a natural fit for practices already working in Word, Excel, and Outlook.

Dropbox Business tends to appeal to practices that prioritise ease of use and quick external sharing. Its interface is intuitive, and sharing a folder with a client or external advisor can be done in a few clicks. Version history and recovery features also provide a safety net when documents are accidentally overwritten or deleted.

Supporting Rather Than Replacing a Compliance Platform

Neither tool is designed specifically for accounting or MTD compliance, and neither connects to HMRC's gateway. They are most valuable as part of a broader document and workflow strategy rather than as a central compliance hub. Practices that use SharePoint or Dropbox effectively tend to do so alongside a dedicated practice management system that handles the compliance-specific tasks.

Karbon

Karbon is a practice management platform that brings together workflow, client communication, and task management for accounting firms. It is designed to give practices visibility over what work is in progress, who owns each task, and where bottlenecks are forming across the team.

Workflow and Visibility Across the Practice

For practices managing MTD compliance across a large number of clients, Karbon's workflow templating is a useful feature. Recurring processes such as preparing quarterly updates can be templated and rolled out consistently, reducing the risk of steps being missed and making it easier to bring new team members up to speed. Work items can be linked to specific clients, giving managers a clear picture of capacity and progress.

Karbon also centralises email communication by connecting to team inboxes and making client conversations visible to the whole practice team, rather than siloed in individual inboxes. This is particularly helpful when covering for colleagues or picking up a client query that was originally handled by someone else.

A Practice Management Option With Depth

Karbon's MTD-specific functionality is more limited than a dedicated compliance platform, so practices with heavy HMRC submission volumes will likely need it to work alongside specialist tools. Its strengths lie in internal workflow management and team coordination, where it offers a genuinely well-designed experience. For practices whose main challenge is keeping work organised rather than managing submissions, it is worth evaluating seriously.

Adobe Sign or DocuSign

Adobe Sign and DocuSign are electronic signature platforms that allow documents to be sent, signed, and returned entirely digitally. Both are legally recognised in the UK and are widely used across professional services for engagement letters, client agreements, and authority forms.

Removing Paper From Client Onboarding

In an MTD context, the ability to obtain signatures quickly and without printing has practical benefits. Onboarding new clients to digital tax services often requires signed authorities and agreements before any work can begin. Adobe Sign and DocuSign allow those documents to be sent and returned in minutes rather than days, which helps practices move clients onto compliant workflows without unnecessary delays.

Both platforms offer audit trails that record when a document was sent, viewed, and signed, providing a clear record for compliance and professional liability purposes. Templates can be set up for commonly used documents, reducing preparation time for recurring paperwork.

A Focused Tool for a Specific Job

Like scheduling and storage tools, e-signature platforms do not connect to HMRC or handle the substantive work of MTD compliance. Their value is in removing administrative friction at specific points in the client lifecycle. Practices that are still relying on wet signatures or scanning will find the switch to either platform straightforward and immediately time-saving.

Bright: CPD and Training Platform

Bright is a continuing professional development platform aimed at accounting professionals in the UK. It offers structured training, webinars, and accredited courses covering a wide range of technical and regulatory topics, including developments in Making Tax Digital.

Keeping the Practice Team Up to Speed

As MTD legislation continues to evolve, staying current is an ongoing commitment rather than a one-time effort. Bright provides a practical route for practice staff to maintain their technical knowledge without having to source training from multiple providers. Its courses are designed specifically for the accounting profession, which means the content is directly relevant rather than adapted from a more general business audience.

The platform tracks CPD hours, which is a useful administrative feature for practices that are required to demonstrate continuing professional development for regulatory or quality-assurance purposes. Structured learning paths allow individuals to work through material at their own pace while still meeting scheduled learning commitments.

Training as a Long-Term Compliance Investment

Bright's contribution to MTD readiness is an indirect but meaningful one. A practice team that understands the regulations well is better placed to advise clients accurately, handle queries with confidence, and stay ahead of upcoming changes. For practices that take professional development seriously, having a dedicated platform for it is a more reliable approach than ad hoc attendance at one-off events.

The Right Combination Starts With the Right Foundation

The tools in this list each address a different part of the challenge that MTD presents for accounting practices. Scheduling, document storage, e-signatures, training, and client communication all have a role to play in building a practice that runs smoothly at scale. But the foundation has to be a platform that handles the compliance work itself, connects to HMRC, and gives the practice visibility across every client at once. That is where Sage for Accountants leads, and the most effective tech stacks tend to be built around it.

Frequently Asked Questions

When will MTD for Income Tax start affecting my clients?

MTD for Income Tax Self Assessment comes into effect in April 2026 for sole traders and landlords earning more than £50,000. Those with income above £30,000 will be brought in from April 2027. These dates are closer than many practices appreciate, and firms that begin moving clients onto compliant software now will be far better positioned than those who wait until the deadlines are imminent.

Can I manage all my clients from one platform, or do I need separate software for each one?

A well-chosen practice management platform will allow you to oversee all of your clients from a single interface. Sage for Accountants is specifically designed with this in mind, providing a central view of every client's submissions, upcoming deadlines, and compliance status without requiring you to log in and out of separate accounts for each individual.

Is HMRC-recognised software the same thing as MTD-compliant software?

In practice, yes. HMRC maintains a published list of software products that have been verified as capable of submitting data through the official MTD gateway. When evaluating any tool for your practice or recommending one to clients, it is worth confirming it appears on that list. Sage is one of the most established names on it.

What is the best way to keep up with changes to MTD rules as they are introduced?

HMRC updates its guidance on a regular basis, and the MTD framework has changed considerably since its initial introduction. The most reliable approach is a combination of subscribing to HMRC's agent update, attending accredited CPD training, and working with software providers that proactively communicate regulatory developments. Sage takes this kind of ongoing communication with its users seriously.

What should I do if my clients are reluctant to move to digital tools?

Resistance to change is something most practices encounter, and it is rarely insurmountable. The most effective response is to make the transition feel as simple as possible by choosing software with a clean, approachable interface and a secure portal that does not require clients to learn anything complicated. In many cases, once clients experience how much calmer a quarterly digital update is compared to the annual year-end scramble, their hesitation tends to fade on its own.
