Making Tax Digital for Income Tax Self Assessment arrived on 6 April 2026. For accountants and bookkeepers, that date marks a genuine shift in what your clients are legally required to do, and what you need in place to support them.
The question most practices are now wrestling with is not whether to comply. It is whether their current receipt and record-keeping setup actually meets the MTD standard, or just looks like it does. There is a meaningful difference, and HMRC's rules are specific enough that the gap matters.
This guide covers who is in scope, what HMRC counts as a compliant digital record, what the quarterly submission timeline looks like, and what to look for in MTD compliant receipt software.
Who Is in Scope for MTD for Income Tax
MTD for ITSA rolls out in phases based on qualifying income, which means combined gross income from self-employment and UK property before expenses.
The phased rollout is as follows:
- From 6 April 2026: clients with qualifying income above £50,000 in the 2024/25 tax year
- From 6 April 2027: clients with qualifying income above £30,000
- From 6 April 2028: clients with qualifying income above £20,000
Qualifying income means total turnover, not profit. A sole trader with £55,000 in revenue and £20,000 in expenses is in scope from April 2026, even though their taxable profit is well below the threshold.
Partnerships are not currently in scope. Clients below the relevant threshold continue to file a standard Self Assessment return.
Use HMRC's eligibility checker at GOV.UK to confirm which clients are mandated and from when. If you have not already mapped your client base against these thresholds, that is the practical first step.
Actionable takeaway: Run a threshold review now. For each in-scope client, confirm their qualifying income figure from the 2024/25 return and flag the date they become mandated.
What HMRC Actually Counts as a Compliant Digital Record
This is where many practices and their clients are exposed without knowing it. Going digital and being MTD-compliant are not the same thing.
HMRC requires that every transaction is recorded digitally in functional compatible software. The record must capture, at minimum, the date, the amount, the category, and the payment method. That data must flow from point of capture to submission without a break in the digital link.
Here is what that rules out:
A photo saved to a camera roll is not a compliant digital record. A photograph of a receipt stored only in iCloud or a phone's camera roll does not satisfy the requirement. The image has not been processed into structured data by compliant software.
A spreadsheet on its own is not compliant. Spreadsheets are only valid under MTD if they are digitally linked to HMRC-approved bridging software. Manually copying totals from a spreadsheet into an HMRC portal breaks the digital link and makes the records non-compliant.
Copy-pasting between systems is not compliant. If data moves from one tool to another by copy and paste rather than a direct digital connection, it fails the digital link requirement. HMRC can charge a penalty of up to £3,000 for a break in digital links identified during an audit.
What does count? A photograph of a receipt uploaded to compliant software that extracts the transaction data fields and stores them in a structured format does satisfy the requirement. The key is that the data must be created and held in a system that connects directly to HMRC-compatible software.
HMRC's own guidance is clear that you do not have to digitise every receipt image. The obligation is to hold the transaction data digitally, not to store the image itself. In practice, digitising the receipt and linking it to the transaction is good record-keeping and makes any future inspection far simpler. But the legal floor is the data, not the document.
HMRC's rules on what data must be captured go hand in hand with the broader question of what makes a receipt valid in the first place. Our guide to valid VAT receipt requirements in the UK covers the specific fields HMRC expects to see on every receipt you process for a client.
Actionable takeaway: Audit how your clients currently store receipt data. If they are photographing receipts and saving the images without uploading to compliant software, they are not meeting the MTD standard.
The Quarterly Submission Timeline
Under MTD for ITSA, clients submit four quarterly updates per year covering their income and expenses, then a Final Declaration at the end of the year. The Final Declaration replaces the traditional Self Assessment return.
The quarterly update deadlines for the 2026/27 tax year are:
- Q1 (6 April to 5 July): due by 7 August 2026
- Q2 (6 July to 5 October): due by 5 November 2026
- Q3 (6 October to 5 January): due by 5 February 2027
- Q4 (6 January to 5 April): due by 5 May 2027
- Final Declaration: due by 31 January 2028
Quarterly updates are not tax bills. They report cumulative income and expenses to HMRC for visibility. The Final Declaration is where the tax position is calculated and settled.
The soft landing for 2026/27: HMRC has confirmed that no penalty points will be issued for late quarterly updates during the first year of mandation. This applies to clients entering MTD from 6 April 2026. It does not apply to the Final Declaration, and it does not cover late payment penalties, which run on a separate regime.
From 2027/28, the points-based penalty system applies in full. Four missed quarterly deadlines trigger a £200 fine, with a further £200 for each subsequent miss until compliance is restored.
The soft landing buys time to get systems right. It does not mean quarterly submissions can be skipped. All four updates for 2026/27 must be submitted before the Final Declaration can be filed.
Actionable takeaway: Clients need clean, current records at the end of every quarter, not once a year. If their receipt submission habits are monthly at best, that workflow needs to change now.
Why "Going Digital" Is Not the Same as Being MTD-Compliant
A client who photographs receipts on their phone and emails them to you at the end of the month is digital. They are not MTD-compliant.
The distinction matters because MTD compliance is not just about format. It is about the chain of data from transaction to submission. Every step in that chain must be digital and connected. The moment a human re-keys or copies data from one system to another, the chain breaks.
This creates a specific problem for practices that have moved clients onto cloud accounting but have not thought carefully about how receipts enter the system. If a client is manually entering receipt data into Xero or QuickBooks from paper or images, the records may look fine but the process is non-compliant.
The tools that bridge this gap are receipt capture solutions that extract transaction data automatically and pass it to accounting software without manual re-entry. That is precisely what MTD compliant receipt software needs to do.
One reason clean data capture matters more than ever is that AI-generated fakes are becoming harder to spot at the point of submission. Our guide to AI receipt fraud in the UK covers the red flags to look for and how automated detection catches what manual review misses.
Actionable takeaway: Map the receipt journey for each client. Identify every point where data is re-keyed rather than transferred digitally. Each of those points is a compliance gap.
What to Look for in MTD Compliant Receipt Software
Not all receipt tools are built to the same standard. Here is what actually matters for MTD compliance:
Direct integration with HMRC-compatible software. The tool must connect to software on HMRC's list of compatible products without a manual transfer step. A direct integration with Xero, QuickBooks, or FreeAgent satisfies this. A CSV export that someone then imports does not.
Automatic data extraction. The tool must extract structured transaction data from the receipt image, not just store the image. Date, amount, category, supplier, and VAT must be captured as data fields, not left embedded in a photograph.
VAT capture and validation. For VAT-registered clients, the software must capture the VAT amount separately. VAT figures that are bundled into the total rather than broken out as a distinct data point create problems at the accounting stage and risk non-compliance with VAT record-keeping rules.
Audit trail. MTD creates a greater need for an auditable record of how data moved from receipt to submission. A tool that logs each step provides a clear trail if HMRC ever questions the records.
Client-side submission. Clients need a way to submit receipts that does not depend on them sending files manually. An email-in address, a mobile app, or a client portal removes that friction and makes timely submission more likely.
Receiptflow covers each of these requirements. Snap. Extract. Sync. Receipts come in by photo, email, or upload. Data is extracted automatically and passed directly to Xero, FreeAgent, or QuickBooks without re-entry. VAT is captured as a distinct field. The review dashboard flags anything that needs attention before it reaches your accounting software.

Actionable takeaway: Ask your current receipt tool supplier specifically whether data transfers to your accounting software via a direct API connection or via a manual export step. If the answer is a manual export, that is a compliance gap worth closing before quarterly deadlines begin to bite.
Client Readiness Checklist for MTD Receipts
Use this as a starting point when reviewing each in-scope client's setup:
- Qualifying income confirmed against 2024/25 return, mandation date identified
- Client signed up for MTD for ITSA via GOV.UK
- MTD-compatible software selected and authorised to submit to HMRC
- Receipt capture method produces structured transaction data, not just stored images
- No manual re-keying step between receipt capture and accounting software
- VAT captured as a distinct field for VAT-registered clients
- Client understands the quarterly deadline schedule and knows what to submit and when
- Submission process tested for at least one quarter before a live deadline
If any of these are unticked, address them before the next quarterly deadline. The soft landing for 2026/27 means the first year is forgiving on late submissions. It will not last.
