Implementing Making Tax Digital for Income Tax for UK Accountants

What is MTD for Self Assessment?

Making Tax Digital for Income Tax (MTD IT) is a phased HMRC mandate requiring self-employed individuals and landlords to submit quarterly income and expense updates via HMRC-recognised software. It took off in April 2026 (£50k+ income), expanding to £30k+ in April 2027 and £20k+ in April 2028.

Understanding MTD IT’s 2026/27 Soft Landing

The first cohort of MTD IT went live on the 6th of April 2026, affecting sole traders and landlords with combined income above £50,000. The good news is that HMRC has granted a one-year soft landing on penalty points for the first cohort’s quarterly submissions during the 2026/27 tax year. This means no penalty points are issued for late submissions this year. However, it’s a grace period, not a permanent fixture. For the final declaration, standard penalties apply regardless. And critically, this soft landing does not extend to the second cohort arriving in April 2027. For further details on the soft landing structure, read our guide on MTD IT’s soft landing and quarterly deadlines.

The four quarterly deadlines for 2026/27 are:

• 7th of August 2026

• 7th of November 2026

• 7th of February 2027

• 7th of May 2027

Was Your Practice Ready for the First MTD IT Deadline?

The first deadline arrived on the 7th of August 2026. And as you’re probably well aware, readiness meant more than having software installed. The practices that came through August 2026 smoothly segmented their clients early. Shoebox clients needed receipt-capture tools, spreadsheet clients needed bridging software, and digital-ready clients just needed review-and-submit workflows. If you had a one-size-fits-all approach, you likely saw a lot of chaos in the run up to the August deadline.

Practice readiness involves several key areas, including:

• Identifying all £50k+ clients

• Confirming digital record-keeping is in place

• Setting up quarterly submission workflows by client type

• Updating fee structures to reflect new touchpoint frequencies

For a more detailed checklist, see our guide for the first MTD IT deadline.

Five Essential Actions for Accountants to Prepare for MTD IT

Rather than reacting to each cohort as it arrives, forward-looking practices are executing five key actions now that scale across all three mandate phases. First, understand what MTD IT actually requires. You must have digital record-keeping from transaction capture through quarterly submission and a final declaration.

Second, invest in software, specifically HMRC-recognised tools that handle your client base’s range of digital readiness. Third, educate your clients to better prepare them for November’s deadline. Remember, most of your clients are relying on you to tell them what they need to do.

Fourth, review and update your internal processes. MTD IT transforms your practice’s workflow from one annual engagement to four additional touchpoints per year, and your task management systems need to reflect this. Fifth, create a timeline and action plan. Don’t leave it all to the last month before a deadline.

For detailed steps on each of these actions, see our guide to five key actions accountants should take.

Preparing for the Second MTD IT Cohort in April 2027

The second cohort (sole traders and landlords with income above £30,000) joins the mandate on the 6th of April 2027. Unlike the first cohort, they get no soft landing. Late quarterly submissions from April 2027 onward accumulate penalty points immediately.

For practices with clients in both cohorts, April 2027 is when the stakes change. Suddenly, every late submission could trigger a penalty. The second cohort’s lack of a soft landing makes April 2027 the month when established MTD IT workflows either make or break your firm.

The practices adapting most successfully are using the 2026/27 soft landing period to establish a successful quarterly workflow completely. Not just for the first cohort but to also effortlessly apply the second cohort’s arrival.

Which MTD IT Software Will Keep Your Practice Compliant?

Not all MTD-compatible software is equal. For example, software vendors that handle only quarterly updates but not the final declaration leave a gap that practices have to fill with another software provider. At Bright, our bookkeeping software, BrightBooks, lets you file quarterly submissions to HMRC, while our tax software, BrightTax, is HMRC-recognised digital tax software for MTD year-end submissions. For a more detailed checklist of software requirements, check out our guide to choosing MTD IT digital tax software that keeps your practice compliant.

Nearly 1 Million People Are Now Under MTD IT. Is Your Software Ready Or Are You the Bottleneck?

By the close of the first cohort registration period, 864,000 taxpayers had registered for MTD IT. However, clients aren’t independently researching MTD IT. They’re waiting for you to tell them what they need to do. Research published in early 2026 found that 39% of small business owners have never heard of MTD for Income Tax, with 19% not understanding anything about it.

To check if your software’s ready, the first question to ask any vendor is if the product can submit a quarterly update directly to HMRC for a sole trader in scope for MTD IT.

If the answer involves manual exports, workarounds, or future features, keep looking.

The second question to ask is will software be updated automatically when rules change. For practices managing large client portfolios, automatic cloud updates are non-negotiable. For a deeper dive on software readiness and what it actually means, see our analysis of whether your software is truly ready for nearly 1 million MTD IT users.

Building an Effective MTD IT Operations System

One practice told us recently that MTD IT doesn’t feel like one new thing, it feels like a hundred new things happening all at once. Managing 50 clients through four quarterly deadlines each is 200 submission events per year, and that’s not even including final declarations! If you manage 100 clients then you’re managing 400 quarterly submissions, plus 100 final declarations.

BrightManager is built as the command centre for this scale. Our pre-built MTD workflows give you portfolio-wide visibility of which MTD IT clients are on track, which are pending, which need urgent follow-up. Automated task creation means once you set a client’s quarterly due date, BrightManager generates the required tasks automatically, names them correctly, dates them accurately, and assigns them to the right team member.

Client chasing becomes automated too. Set how many days after the last quarter that you want next quarter’s records requested, and the system sends out the email. The emails use smart variables to pull in specific client details and exact dates so they read personally written, not robotic. For a 100-client MTD IT portfolio, bulk editing saves hours upon hours per cohort. See our full guide to BrightManager’s MTD IT compliance features for feature details and implementation steps.

How to Manage Large MTD IT Client Portfolios Without Hiring

ICAEW’s workflow guidance for MTD IT acknowledges the challenge that managing a large client list of four quarterly deadlines every year is complicated without the right systems in place. A practice with 100 MTD-eligible clients is managing 400 quarterly updates and 100 final declarations per year on top of everything else they have to do.

The practices that absorb this workload without hiring are the ones that have three things in place:

1. Portfolio-wide visibility (a single dashboard showing every client’s MTD IT status and outstanding deadlines)

2. Standardised quarterly workflows (the same sequence for every client, every quarter)

3. Client-side data capture that doesn’t require the practice to chase (clients submit records continuously rather than in batches)

BrightBooks gives clients a frictionless way to photograph receipts and log income throughout the quarter via its document capture tool. BrightManager provides the portfolio visibility and automated task management. BrightTax handles year-end submissions. Used together, they eliminate the data re-entry cycle and reduce manual administration dramatically.

A 50-client MTD portfolio requires deliberate workflow design. Segment clients by digital readiness, assign the appropriate tools to each segment, and use BrightManager to track deadlines across the entire portfolio. This is how practices manage scale without hiring. For detailed workflows on managing large MTD IT portfolios, see our guide to managing 50+ MTD IT clients without expanding your team.

MTD IT Workflows for Shoebox, Spreadsheet, and Digital-Ready Clients

Most practices are dealing with mixed client bases when it comes to MTD IT. Some clients are already operating their bookkeeping through the cloud and barely need guidance, some work from spreadsheets and need transition plans, and some still collect receipts in folders and reconcile once a year. The practices struggling most are those trying to apply a single type of workflow to all of their clients.

Shoebox clients need a staged shift. Move them from bank feeds to a connected cloud bookkeeping tool so that income and expenditure from the bank account is captured automatically without manual entry. Introduce a receipt-capture app so the client just photographs receipts as they incur them rather than filing them for later. Also, review the records at the end of each month (not the quarter) to catch gaps and categorisation errors.

Spreadsheet clients have two routes available. The first is bridging software that keeps the spreadsheet but adds an electronic link to an HMRC-recognised submission tool, or migration to a cloud bookkeeping that removes the manual linking step at each quarter and gives you a cleaner, more auditable record trail.

Digital-ready clients are already using cloud bookkeeping. For these clients, the quarterly MTD IT workflow should be largely automated. The risk is over-engineering the process, like adding manual review steps that aren’t necessary.

Mixed practices need a workflow system that handles all three segments without maintaining three separate processes. That means segment-appropriate onboarding, a single portfolio dashboard that tracks all client deadlines regardless of their digital readiness, with status visible at manager and practice level, and a quarterly rhythm that works for each segment. For a detailed workflow guide tailored to mixed-client practices, see our guide to MTD IT workflows for mixed client practices from shoebox to digital-ready.

What Do Your Clients Need to Know About HMRC MTD for Income Tax Changes?

If your clients understand their MTD IT obligations and are prepared, your compliance work becomes manageable. If they’re confused or unprepared, your practice absorbs the burden.

Clients need to know that MTD IT is a legal requirement and is not optional for those above the threshold. HMRC-recognised software must be used for digital record-keeping. Quarterly submission deadlines are fixed and non-negotiable. The soft landing also just applies for the 2026/27 tax year, it’s not permanent.

Clients also need to understand the change of work involved. Instead of one annual tax return, they’re now submitting four quarterly updates along with a final declaration. This requires ongoing record-keeping, not just a year-end rush. Many clients may resist this until they experience how much easier quarterly reviews are than digging through a year’s worth of paperwork in December and January.

Frequently Asked Questions on Making Tax Digital for Income Tax

The Road Ahead: Act Now, Scale Confidently

The first deadline has passed, with the second happening on the 7th of November. The second cohort arrives in April 2027 with no soft landing. The third cohort follows in 2028.

The practices that will thrive are the ones that are building their workflows now and using the soft landing year to test and refine. They’re segmenting their clients by digital readiness, choosing integrated software that covers the full MTD IT workflow.

The practices that will struggle are the ones treating the soft landing as permission to defer any legitimate action until 2027. When the second cohort arrives and penalty points start accumulating, so deferral could quickly become crisis management.
