Managing Client MTD Exemption Applications

September 19, 2026 3 min read

Quick answer: For clients who may qualify for a digitally excluded, foster carer, or non-resident exemption from MTD for Income Tax, your role is confirming genuine eligibility, helping them apply directly to HMRC (the exemption isn’t automatic), and keeping their ongoing Self Assessment obligations on track separately from any MTD-mandated clients.

Not every client should be onboarded onto MTD software the moment their income crosses the threshold. A small number will genuinely qualify for an exemption, and handling that correctly matters as much as handling standard mandation correctly.

Who to screen for an exemption

The main categories are age, disability, remote location without reliable internet, religious grounds, and foster carers, alongside the specific non-resident easement for those who filed the SA109 pages on their 2024/25 return. See our full explainer on the digitally excluded exemption and MTD for non-UK residents for the detail on each.

Your role in the application

The exemption isn’t granted automatically, even to clients who clearly meet the criteria; someone needs to actively apply to HMRC and set out the circumstances. As their agent, you’re often best placed to prepare that application, particularly gathering the supporting detail HMRC will want (nature of the disability or circumstance, why it makes digital record-keeping genuinely impractical, not just inconvenient).

Managing the client afterward

Once granted, an exempt client continues on the traditional annual Self Assessment process, no MTD software, no quarterly updates. It’s worth keeping a clear internal flag on these clients so they’re not mistakenly swept into your practice’s standard MTD onboarding workflow, and worth checking periodically whether their circumstances (and therefore their exemption) still hold.

Where the bar sits

HMRC’s threshold is genuine impracticability, not client preference for the old system. Setting this expectation clearly with clients who ask about an exemption purely because they’d rather not deal with software saves a difficult conversation later if HMRC declines the application.

Frequently asked questions

Can I apply for an exemption on a client’s behalf without them being directly involved?
You can prepare and support the application as their agent, but HMRC will generally expect the application to reflect the client’s genuine, first-hand circumstances.
How long does HMRC typically take to decide?
This varies, and isn’t published as a fixed turnaround; build in enough lead time before a client’s expected mandation date rather than applying at the last minute.
What if a client’s exemption application is declined?
They’ll need to proceed with standard MTD onboarding; at that point, treat it the same as any other client onboarding, using your client onboarding checklist.
Does an exemption apply permanently once granted?
It’s based on ongoing circumstances rather than a one-time assessment; if a client’s situation changes in a way that would affect eligibility, that should be reported.
