HMRC's Making Tax Digital programme replaces the old once-a-year Self Assessment with four quarterly digital submissions plus a Final Declaration. From April 2026, MTD is mandatory for self-employed people earning over £50,000 — and it expands every year, eventually covering all CIS workers, sole traders and landlords.
The headline problems for most workers:
That's where Maximum Rebate comes in. We don't just file your MTD returns — we own the entire process, end-to-end, with no software for you to learn and no extra cost on top of what you'd normally pay an accountant.
We didn't bolt MTD onto an old workflow. We commissioned our sister company, SmartScan IT Group, to build a bespoke automation platform that connects directly to HMRC, your CIS contractors, and your real-time tax position.
Every client, every quarter, every CIS deduction — recorded in our secure UK-hosted client database. One source of truth, accessible to your dedicated account manager.
Make (formerly Integromat) orchestrates the whole workflow — pulling CIS statements, updating quarterly figures, triggering deadline reminders, and routing data to HMRC's MTD API.
Submissions go through 123 Sheets, an HMRC-approved MTD bridging provider. We hold the connection, you don't pay the licence.
Sign in to your private dashboard any time to see your live MTD position, deadlines, filed quarters and downloadable documents. Updated automatically as your account manager confirms each quarter.
Direct WhatsApp line to your named account manager. Send a receipt, ask a question, get a quick answer — same day, no phone tag.
All credentials encrypted in transit (256-bit TLS) and at rest. GDPR-compliant, ICO-registered, hosted entirely in the UK.
Behind the simple client experience is a tightly orchestrated workflow that runs in the background while you get on with the job.
You complete the secure online sign-up. Make captures your details and writes them straight into Airtable.
Our team verifies your HMRC Government Gateway access and pulls your prior Self Assessment data.
Each quarter, your account manager confirms your CIS income, deductions and expenses. Airtable updates in real time.
Figures route through 123 Sheets to HMRC's MTD API. Confirmation is logged and your portal updates instantly.
At year-end we file your Final Declaration, reconcile all CIS deductions, and confirm your final tax position.
No setup fees. No software costs. No per-submission charges. One transparent monthly subscription and we handle every quarter.
Yes — once MTD applies to you, HMRC requires four quarterly updates plus a Final Declaration. The good news: you don't have to do any of it. We handle every submission on your behalf.
From April 2026, MTD applies to self-employed people and landlords earning over £50,000. From April 2027, it drops to £30,000. From April 2028, £20,000. If you're CIS, sole trader or self-employed, you'll be in scope sooner rather than later.
No. Our subscription covers the HMRC-approved 123 Sheets bridging licence. You don't need QuickBooks, Xero, FreeAgent or anything else. Just send us your receipts and statements as you get them.
You won't — that's the whole point of having us. Deadlines are baked into our automation and your account manager confirms each filing well in advance. Since launching MTD Complete, our clients have had zero late-filing penalties.
Yes — your client portal shows every quarterly submission, the figures included, and the HMRC confirmation reference. Try the demo to see how it works.
