Q4 Tax Planning MTD 2025 : Helping Accountants Prepare for MTD

Q4 for accountants is never “quiet.” Between client queries, year-end planning, and juggling HMRC
deadlines, it’s already a plate-spinning act. And now, with Making Tax Digital (MTD) in full swing, the admin
load is only getting heavier.
But with the right systems (and support) in place, Q4 doesn’t have to feel like a marathon of spreadsheets,
late-night reconciliations, and frantic client reminders.

MTD in 2025: Why Q4 Matters for Accountants

MTD isn’t new, but this year it’s stepped up:
• VAT: Almost everyone VAT-registered is already under MTD.
• Income Tax Self-Assessment (ITSA): From April 2026, self-employed clients and landlords earning over
£50k will need to report digitally.
• Corporation Tax: Not mandatory yet, but pilot schemes are underway.
That makes Q4 the perfect time for accountants to get ahead, not just for compliance, but to ease the
admin burden in January and beyond.

Where the Admin Stress Creeps In

Ask any accountant what slows them down, and the list will look like this:
• Chasing clients for receipts, invoices, or missing records.
• Reconciling multiple spreadsheets or outdated systems.
• Double-checking figures before submission because data isn’t centralised.
• Training clients who still resist the “digital shift.”
Sound familiar? That’s why Q4 is your golden window to tidy processes, shift clients onto digital tools, and
lighten the workload before the year-end crunch.

5 Practical Steps for Accountants This Q4

1. Audit Your Client Base

Who’s already MTD-ready, and who still needs a nudge? Create a quick client matrix:
Compliant , In progress , Not started .
This makes it easier to prioritise your time.

2. Standardise Your Software Stack

The more platforms you’re juggling (Xero here, spreadsheets there, bespoke systems somewhere else), the
more admin it creates. Q4 is a great time to guide clients towards a standard set of MTD-ready tools, which
saves you headaches later.

3. Get Ahead of Deadlines

Yes, ITSA doesn’t go live until 2026. But use this quarter to:
• Educate clients about what’s coming.
• Encourage trial runs of quarterly reporting.
• Set up workflows now so it’s smooth when the rules finally hit.

4. Lean on Outsourced Support

If you’re drowning in admin, don’t wait until January to get help. Outsourced bookkeeping, payroll, or data-
entry support can free up your team to focus on advisory work and higher-value tasks.

5. Turn Compliance into Client Value

Instead of positioning MTD as “yet another HMRC box to tick,” show clients how digital records give them
real-time insights. That way, you’re not just their tax person, you’re their business partner.
