SVC / 05 — MTD ITSA

MTD ITSA. Ready for the rollout.

From April 2026, landlords and the self-employed with income over £50,000 must file quarterly digital updates to HMRC. From April 2027, the threshold drops to £30,000. Missing Information has been running MTD ITSA workflows with pilot practices since 2024. When the widening rollout hits, your firm will already know the drill.

Apr 2026 £50k+ mandatory Apr 2027 £30k+ widens 5×/yr deadlines per client 1m + 5d filing window
5 deadlines per client, per year

What MTD ITSA actually means for your workflow.

Instead of one annual SA return, affected clients submit: Q1 by 7 Aug, Q2 by 7 Nov, Q3 by 7 Feb, Q4 by 7 May, and a final declaration by 31 Jan — five submissions per taxpayer per year. For a firm with 200 ITSA clients, that's a thousand deadlines. Missing Information is the only way this scales without drowning your team.

  • Separate self-employment and property tracks for clients with both
  • Cumulative or in-period reporting — your call per client
  • Quarterly checklist rolls forward automatically
  • Final declaration reconciles the year and triggers last info request

Two income streams, one client

Landlords and self-employed? Tracked separately.

Many affected taxpayers have both property income and self-employment. Under MTD ITSA they submit them separately. Missing Information maintains parallel tracks for each income source on the same client — with matching quarterly cadences but independent item checklists.

  • Separate income streams — no mixing self-employed & property
  • Independent checklists per track, per quarter
  • Combined client view — all streams at a glance
  • Unified portal — client uploads once, we route it

Frequently asked

The questions everyone asks.

Quick answers to the most common questions about Missing Information. For more, see our full FAQ.

What does Missing Information actually do?

It tracks every piece of missing information your clients owe you across every UK accountancy service — Accounts, VAT, PAYE, Self Assessment and MTD ITSA. It gives you a daily chase queue with pre-built emails, lets clients upload documents through a secure portal, and shows your team what's ready to work on. It replaces spreadsheets, scattered email threads and Post-it notes with one auditable workflow. Fully-automated chase emails on a scheduled cadence are on the roadmap for later in 2026.

Will it integrate with my existing accounting software?

Yes. Missing Information sits alongside Xero, QuickBooks, FreeAgent and Sage. We don't replace your accounting software — we handle the missing-info chasing layer above it. Direct sync with Xero is available now; QuickBooks and FreeAgent integrations are on our roadmap. We also support Zapier webhooks for custom flows.

How long does setup take?

About four hours from signup to your first live chase email. Bulk-import your client list (we accept pipe-delimited, CSV, or Xero export), assign staff, set service templates, and the system is running. Truetax onboarded 88 clients in an afternoon. The Firm and Scale plans include a guided onboarding call.

Is my client data secure?

Yes — every piece of client data is encrypted at rest (AES-256) and in transit (TLS 1.3). All data is hosted in UK data centres. We're GDPR-compliant, sign DPAs as standard, virus-scan every uploaded file, and align our security controls to ISO 27001. Full details on our security page.

What does it cost?

Plans start at £29/month for sole practitioners (up to 25 clients) and go up to £349/month for unlimited clients. Pricing is by client count only — every feature is included on every plan. 14-day free trial, no credit card required. See full pricing.

Can I cancel any time?

Yes. Cancel from your account dashboard at any time. Monthly plans stop at the end of the billing month. Annual plans run to the end of the paid year. We provide full data export — your client list, status histories and audit logs — in CSV or JSON. No lock-in.

What happens if my clients don't engage with the portal?

The portal uses passwordless magic-link login — no password to remember, no app to install. Clients click a link in an email and they're in. Across 88 clients at Truetax, portal adoption hit 92% within two weeks. For the remaining 8%, you can still operate by email or phone — Missing Information tracks both.

Do you offer a demo before I commit?

Yes. Book a 30-minute demo with someone from our team and we'll walk you through the system using a sample firm. We can also give you a sandbox workspace with anonymised demo data to explore for a few days before starting your trial.
