Making Tax Digital for ITSA is no longer a future problem to plan around: for many UK accounting practices, it is now a live, quarterly admin workload. With the first cohort of sole traders and landlords now required to keep digital records and submit quarterly updates, practices that haven’t restructured their processes are starting to feel the strain on staff time and client communication.
What Is Making Tax Digital for ITSA (MTD for ITSA) and Who Does It Apply To?
Making Tax Digital for Income Tax Self Assessment replaces the old annual Self Assessment return with digital record-keeping and quarterly updates submitted through compatible software. From April 2026, sole traders and landlords with qualifying income over £50,000 must log income and expenses digitally and send HMRC a summary every quarter, followed by a final declaration at year end, according to GOV.UK’s official guidance. For practices, this means the single annual tax return job has effectively multiplied into five separate submissions per client, per year.
The 2026 Rollout: What’s Live Now for Accounting Practices
Making Tax Digital for ITSA is being introduced in phases based on income level, which means practices are now juggling clients on different timelines and rules simultaneously. Some clients are already inside the quarterly cycle, others are preparing to join in the next phase, and many are still unsure which category they fall into. That uncertainty lands squarely on the practice’s desk, in the form of client queries, software onboarding, and repeated explanations of what MTD for ITSA actually requires from them.
Why MTD for ITSA Is Creating an Admin Workload Crunch
The workload increase isn’t just about extra deadlines on a calendar. It’s the volume of small, repetitive administrative tasks that come with each submission cycle: chasing bank statements and receipts, reconciling digital records, checking software categorisation errors, and correcting client mistakes before each quarterly filing.
Quarterly updates multiply the touchpoints per client
Where a practice once had one significant contact point per client per year for Self Assessment, Making Tax Digital for ITSA now requires four quarterly touchpoints plus a final declaration. Multiply that across a full client bank and the admin burden becomes substantial, even if each individual submission is relatively quick. Much of that extra workload sits in the same territory as everyday practice admin, which is also why getting client onboarding right matters more than ever, since a clean file from day one makes each quarterly update faster to process.
In-House vs Outsourced: Managing the MTD for ITSA Workload
- In-house: Keeps oversight fully internal, but adds recurring administrative hours to already-stretched accountants and bookkeepers during busy periods.
- Outsourced: Shifts the repetitive data entry, chasing, and reconciliation work to a dedicated support team, freeing qualified staff to focus on advisory work and exceptions.
- Hybrid: Many practices are now outsourcing the routine quarterly admin while keeping final review and client sign-off in-house.
The same in-house-vs-outsourced calculation applies to other compliance-heavy admin, including AML checks for accounting practices, where outsourcing frees up the same qualified staff time.

These are real questions UK accounting practices and their clients are currently typing into Google about Making Tax Digital for ITSA.
What does MTD for ITSA stand for?
MTD for ITSA stands for Making Tax Digital for Income Tax Self Assessment. It’s HMRC’s programme requiring sole traders and landlords to keep digital records and submit income and expense updates through compatible software, rather than filing a single annual Self Assessment return.
What is qualifying income for Making Tax Digital?
Qualifying income is your combined gross income from self-employment and property before expenses, not your profit. From April 2026, anyone with qualifying income over £50,000 must comply, with the threshold dropping to £30,000 from April 2027 as HMRC widens the scope in later phases.
How does MTD ITSA work?
Once registered, you keep digital records of business income and expenses in HMRC-recognised software, send a quarterly summary update to HMRC every three months, and submit a final declaration after the tax year ends to confirm your total taxable income and any adjustments.
What records do I need for MTD?
You need digital records of every business transaction, categorised by income and expense type, and kept separately for each self-employment business or rental property you have. Paper receipts and spreadsheets alone are no longer enough unless they feed into MTD-compatible bridging software.
How much does Making Tax Digital cost?
Compatible software typically costs somewhere between £5 and £30 per month per client, depending on the provider and features you choose from HMRC’s list of MTD-compatible software. On top of that, most practices also factor in the extra staff time needed to review and submit four quarterly updates instead of one annual return, which is often the bigger cost.
Are you ready for Making Tax Digital?
A practice is genuinely ready when every affected client has been identified, signed up with HMRC, set up on compatible software, and briefed on what data to send each quarter. If any of those steps are still outstanding across your client bank, it’s worth prioritising them before the next filing deadline lands.
