Making Tax Digital For Bookkeepers: What Changes April 2026 (And How To Reprice For It)

Making Tax Digital for Income Tax launched on 6 April 2026, and your first quarterly submission deadline is 7 August 2026. If your practice has any client earning over £50,000 in combined self-employment and property income, that client is now in scope under HMRC's published rules and you owe HMRC a quarterly update by 7 August covering the quarter from 6 April to 5 July 2026. That deadline is ten weeks out from today.

The framing now is execution: which clients are actually in scope, which software to recommend now that HMRC has dropped the static approved-software list, how to reprice the five-filings-per-year workload before the Q2 deadline, and how to communicate the change to existing clients without losing them.

What MTD-ITSA actually changed on 6 April 2026

Per HMRC's official collections page (last updated 17 December 2025), Making Tax Digital for Income Tax requires sole traders and landlords above the income threshold to keep digital records and submit quarterly updates to HMRC, instead of filing one annual Self Assessment return. The threshold is staged: over £50,000 in April 2026, dropping to over £30,000 in April 2027, and dropping again to over £20,000 in April 2028, per the AAT MTD centre.

The income test combines self-employment income (Self Assessment SA103) and property income (SA105 for UK property, SA106 for foreign property). Salary, pensions, dividends, and investment income do not count toward the threshold per Sage UK's income-test guide. The test is run on the 2024/25 tax return: if combined gross self-employment plus property income on that return is over £50,000, the client is in MTD from April 2026.

The practical change for the bookkeeper: each in-scope client now files five times per year instead of once. Four quarterly updates plus the annual Final Declaration. Per The 6 Figure Bookkeeper's What is MTD for IT writeup, that means "five filings per client over the course of the year" where previously there was one. The workflow change is structural, not incremental.

"MTD doesn't overwhelm well-prepared firms; it only overwhelms late ones."

Your Q1 deadline: 7 August 2026

The four quarterly submission deadlines for the 2026-27 tax year are fixed in HMRC's calendar. Per MTD.digital's deadline guide:

The annual Final Declaration for the 2026-27 tax year is due 31 January 2028, which replaces the standard Self Assessment return.

What goes in a quarterly update is the cumulative income and expenses for the quarter, posted from the digital records the bookkeeper keeps in MTD-compatible software. It is not a full P&L; it is a totals-by-category submission with figures running cumulatively across the four quarters. The Final Declaration is where adjustments, accruals, prepayments, and capital allowances are posted.

The Q1 deadline is the one that exposes practices. Q2 is when the workflow has to be cadenced. By Q3 the practice either has the rhythm or has lost clients to a competitor who does.

Which of your clients are actually in scope now

The target reader of this post has a practice with around 12 clients, many of them earning under £50,000 each. Most are not mandated for MTD in 2026. They are in scope from April 2027 (if over £30,000) or April 2028 (if over £20,000). Some may choose to sign up voluntarily.

Three buckets, sorted now:

Bucket 1: In scope April 2026 (over £50,000 combined SE + property). These clients owe Q1 submission by 7 August. The bookkeeper has to confirm authorised-agent status with HMRC for each one, confirm software choice, and confirm pricing for the new workflow.

Bucket 2: In scope April 2027 (£30,000-£50,000 combined). These clients have a strategic window. The bookkeeper has a year to transition them to MTD-compatible software, train them on the digital-records requirement, and reprice. Doing the transition during the 2026-27 soft-landing year (no penalty points for late quarterly submissions) is the cleanest path; doing it after April 2027 means the client is learning the workflow under penalty pressure.

Bucket 3: In scope April 2028 (£20,000-£30,000 combined). Two-year window. The bookkeeper can defer the conversation but should still flag the schedule at the next planning meeting so the client is not surprised in 2027.

Some sub-£50,000 clients will ask about voluntary sign-up. The practitioner answer is usually no, unless the client wants the cleaner digital records for non-tax reasons (lending, grant applications, business planning). Voluntary sign-up adds workflow now without a tax benefit; wait for the mandate.

The software choice (HMRC removed the static list)

This is the structural change most practitioners underweight. Per the HMRC software finder page (last updated 8 May 2026), the static table of approved software was removed in July 2025. HMRC now points users to a dynamic finder tool and a list of providers building MTD-compatible products. There is no longer a "HMRC-approved list" the bookkeeper can hand the client.

The practical consequence: software choice is per client and has to be vetted by the bookkeeper. The market-leading platforms in mid-2026 are FreeAgent, Xero, QuickBooks Online, FreshBooks, and Sage. Each has MTD-ITSA-compatible offerings at different price points. The bookkeeper's role is to match the client's workflow (sole trader, landlord, mixed) to the platform's strengths, not to pick a default.

Per Eco Accounts' March 2026 cost analysis, the market range for the software itself is "around £10 to £30 per month" and the range for outsourced MTD bookkeeping is "£75 to £150 per month." These two ranges are passed through to the client separately: software is a client cost billed directly by the platform; the bookkeeping service is the bookkeeper's fee on top.

The bookkeeper-software-stack post walks through the QBO vs Xero vs FreshBooks recommendation framework in detail for the bookkeeper-as-advisor angle. For UK clients in scope for MTD, Xero and FreeAgent dominate the practitioner conversation; QuickBooks Online and Sage have a smaller share of the UK MTD market.

The repricing math (and the 32% problem)

This is the section every practitioner reads twice. Per The 6 Figure Bookkeeper's July 2025 pricing survey of 60 bookkeepers, 28% of respondents expected to charge £251 to £500 per year for MTD services. 32% said they did not know what to charge. That second number is the warning: a third of UK bookkeepers entered the live MTD-ITSA year without a price set for the new workflow.

The repricing math is direct. Five filings per client per year instead of one means roughly five times the touchpoints with the client's records. The cadence change alone is the cost. Practitioners who priced the pre-MTD annual workflow at £600 per year for a small sole trader are now doing five filings for the same fee, which is unprofitable on a per-touchpoint basis.

The market answer per Eco Accounts is £75 to £150 per month for outsourced MTD bookkeeping (£900 to £1,800 per year per client) on top of the £10 to £30 per month the client pays for software. £600 per year becomes £900 to £1,800 per year; practices that do not reprice are running the new workflow at a loss.

Per the 6 Figure Bookkeeper repricing methodology, the cleanest framing is "service restructuring" rather than "price increase." The client is buying a different service now (quarterly compliance plus annual reconciliation) than they were buying before (one annual filing). Repricing maps to the service change, not to inflation. According to Max Whiteley of 6 Figure Bookkeeper, the practical rule is to evaluate how long each filing takes per client and price accordingly, rather than holding pre-MTD prices flat against the new five-touchpoint workload.

The penalty-relief year: how to use it strategically

Per HMRC's MTD penalties guidance, the 2026-27 tax year has soft-landing relief: no penalty points for missing a quarterly update deadline in the first year. This is not a permission to skip submissions; it is a learning window. The penalty-points regime starts properly from April 2027.

Two things to clarify about the soft-landing:

1. Late quarterly submissions in 2026-27 do not accrue penalty points. A late Q1 in August 2026 does not earn a point. A late Q1 in August 2027 does.
2. Late-payment penalties apply after a 30-day grace window from day one. This is separate from the points regime. If a client's tax payment is more than 30 days late, HMRC applies financial penalties starting in the 2026-27 year, not waiting for 2027.

The strategic use of the soft-landing year: use Q1 (7 August 2026) and Q2 (7 November 2026) to dial in the cadence with each in-scope client. By Q3 (7 February 2027), the workflow should be smooth enough that Q4 lands without scrambling. Practices that miss this window enter April 2027 with the workflow still rough and the penalty regime fully active.

"There'll be nearly a million people trying to sign-up next April, and most of them will wait until the last minute."

Source: Rebecca Benneyworth, quoted in Sage UK, "Sign up clients to MTD before the April deadline" (December 2025)

The same pattern repeats in April 2027 when the £30,000 threshold brings the next cohort in. Practices with capacity in early 2027 will be in a stronger position to take new MTD-onboarding work than the late-mover competitors who held their pre-MTD prices flat through 2026.

The client-communication script

The 32% who did not know what to charge by July 2025 still owe their clients a conversation. The script that works:

1. Open with the workflow change, not the price. "MTD-ITSA went live on 6 April. From now, instead of one annual filing for your business, HMRC requires four quarterly submissions plus the annual Final Declaration. That is five filings per year for your business."
2. Name the per-client implication. "For your engagement specifically, that means we will close your books quarterly instead of annually. Each quarterly close needs your records up to date by the cutoff date so we can submit by HMRC's 7 August / 7 November / 7 February / 7 May deadlines."
3. Present the repricing as service restructuring. "Because the service is genuinely different now (quarterly compliance plus annual reconciliation instead of one annual filing), the engagement letter needs an update. The new fee for the quarterly-cadence service is £[X] per month, which covers the four quarterly submissions and the Final Declaration."
4. Separate software cost cleanly. "The MTD-compatible software runs £[X] per month and is billed directly to you, not through me. I will recommend the right platform for your records but the software subscription is in your name."
5. Anchor on the Final Declaration date. "Your first Final Declaration under MTD is due 31 January 2028 for the 2026-27 tax year. The quarterly cadence we set up now is what makes that deadline straightforward in January 2028."

The uk-freelance-bookkeeper-rates post walks through the broader rate-setting framework that this MTD repricing fits inside. The rates post is the pre-MTD pricing baseline; this post is the MTD-specific service restructuring.

The practitioner checklist for the next 10 weeks

The Q1 deadline at 7 August is the first cadence test. Q2 at 7 November is the real one, when the workflow either works at scale across the practice or breaks. Practices that have priced the new workflow and trained the in-scope clients by Q2 enter April 2027 with capacity to take on the next mandate cohort; the rest spend 2027 catching up.
