What is Making Tax Digital?
Making Tax Digital is HMRC’s long-running programme to modernise the UK tax system by moving it from paper-based administration to digital record-keeping and electronic submission. The core principle is straightforward: businesses and individuals keep their tax records in digital form, using compatible software that connects directly to HMRC’s systems.
The programme was first announced in 2015 as part of the government’s “tax administration for the 21st century” agenda. The original ambition was sweeping — to create a near-real-time tax system where HMRC could see a running picture of each taxpayer’s position throughout the year, rather than waiting for an annual return filed months after the year ended.
In practice, the rollout has been phased and repeatedly delayed. MTD for VAT was the first pillar, going live in April 2019 for businesses above the VAT threshold. MTD for Income Tax Self Assessment (ITSA) was originally scheduled for April 2018 but has been postponed five times. It is now confirmed for April 2026.
The three pillars of Making Tax Digital
- MTD for VAT — mandatory for all VAT-registered businesses since April 2022. Requires digital VAT records and electronic VAT return submission through compatible software.
- MTD for Income Tax (ITSA) — begins April 2026 for sole traders and landlords. Requires digital income/expense records and quarterly submissions to HMRC.
- MTD for Corporation Tax — no confirmed start date. HMRC has stated its intention but no legislation is in place. Not expected before 2028 at the earliest.
The underlying goals haven’t changed since 2015: reduce the “tax gap” (the difference between tax owed and tax collected), improve accuracy of returns, give businesses a clearer real-time picture of their tax position, and modernise HMRC’s infrastructure. Whether the execution matches the ambition remains a live question — but the legislative framework is now firmly in place.
MTD for VAT: the story so far
MTD for VAT is the most mature part of the programme and the one most businesses have already experienced. Understanding how it works provides useful context for what’s coming with Income Tax.
The phased rollout
MTD for VAT launched in April 2019 for businesses with taxable turnover above the VAT registration threshold (£85,000 at the time). From April 2022, the threshold was removed entirely — all VAT-registered businesses, regardless of turnover, must now comply.
This means every business on the UK VAT register — whether turning over £90,000 or £9 million — must keep digital VAT records and file their VAT return through MTD-compatible software. Roughly 2.1 million businesses are now filing under MTD for VAT.
What MTD for VAT requires
Digital VAT records
You must maintain digital records of all supplies made and received, the VAT charged, and the time of supply. These records must be kept in compatible software (or a spreadsheet with bridging software). Paper VAT books are no longer acceptable for businesses in scope.
Electronic submission
VAT returns must be submitted to HMRC directly from your compatible software via HMRC’s API. You cannot type the nine-box figures into the HMRC website manually. The software must transmit the data electronically.
Digital links
Where VAT data passes between different systems (for example, from a point-of-sale system to accounting software), the transfer must be digital. Copying numbers by hand from one screen to another breaks the “digital links” requirement. The full chain from source transaction to submitted return must be connected digitally.
For most businesses using modern accounting software — Xero, QuickBooks, Sage, FreeAgent, Pandle — compliance has been relatively painless. The software handles digital record-keeping and submission automatically. The friction has been felt most by businesses that were still using paper records or disconnected spreadsheets when the mandate arrived.

MTD for Income Tax (ITSA): what’s coming
MTD for Income Tax Self Assessment is the next major expansion of the programme — and the one generating the most anxiety among sole traders, landlords, and accountancy practices. The legislation is in place, the HMRC beta has been running since April 2025, and the penalty framework is built.
This is no longer speculative
MTD ITSA has been delayed five times since its original 2018 target. The “cry wolf” effect is real — many practitioners have stopped taking the dates seriously. But this time, the Finance Act provisions are enacted, HMRC is processing real submissions through the beta, and the software ecosystem is live. April 2026 is the date.
Who is affected
MTD for ITSA applies to individuals with qualifying income from self-employment and/or property letting. The threshold test is based on gross income (turnover), not profit. A sole trader taking in £55,000 with £40,000 in costs is still in scope despite only making £15,000 profit.
Qualifying income includes:
- Self-employment income (all trades combined)
- UK property income (residential and commercial lettings)
- Overseas property income
It does not include employment income, pension income, dividends, savings interest, or capital gains. A landlord earning £45,000 in rental income and £100,000 from PAYE employment is not caught at the £50,000 threshold — only the rental income counts.
Partnerships have been deferred indefinitely. HMRC remains “committed” to bringing them into scope, but no date has been set. Limited companies are not affected by MTD ITSA at all — Corporation Tax is a separate (unconfirmed) workstream.
Quarterly reporting
The central change from the existing Self Assessment regime is the move from annual to quarterly reporting. Four times a year, you submit a summary of income and expenses to HMRC through compatible software.
These are not mini tax returns. There are no capital allowance calculations, pension relief claims, or loss relief adjustments in the quarterly submissions. They are summaries of income received and expenses incurred, mirroring the categories on the existing SA103F (self-employment) and SA105 (property) supplementary pages.
The quarterly submissions are cumulative — each submission shows year-to-date figures, not just that quarter. If Q1 contains an error, it can be corrected in the Q2 submission without penalty.
Separate submissions per business
A sole trader who also rents out property needs eight quarterly submissions per year — four for the trade, four for the property. Someone with two trades and a property: twelve submissions. This catches many people off guard. For a deeper analysis, see our dedicated MTD ITSA article.
The Final Declaration
After the four quarterly updates, there is a Final Declaration due by 31 January following the tax year. This replaces the old Self Assessment return. It’s where you declare other income sources (employment, dividends, savings), claim reliefs and allowances, make adjustments, and confirm everything is correct.
The End of Period Statement (EOPS) that was originally planned as a separate step has been absorbed into the Final Declaration, simplifying the process slightly.
Crucially, you cannot file the Final Declaration unless all four quarterly updates have been submitted. The strategy of “skip the quarterlies and file everything at the end” is not available.
Key dates timeline
The MTD programme has evolved over seven years. Here is the complete timeline of major milestones — past, present, and future.
MTD for VAT launches (Phase 1). Mandatory for VAT-registered businesses with taxable turnover above £85,000. Around 1.2 million businesses affected.
MTD for VAT extended to all. The turnover threshold is removed. All VAT-registered businesses must comply, regardless of size. Approximately 2.1 million businesses now in scope.
New penalty regime goes live for VAT. The old default surcharge system is replaced by the points-based late submission and late payment penalty framework.
MTD ITSA public beta opens. Sole traders and landlords can voluntarily sign up to test the quarterly reporting system with real HMRC submissions.
MTD for Income Tax: Phase 1. Mandatory for sole traders and landlords with gross qualifying income above £50,000. Quarterly submissions begin. First-year grace period on submission penalty points.
MTD for Income Tax: Phase 2. Threshold drops to £30,000. Approximately 760,000 additional taxpayers brought into scope.
MTD for Income Tax: Phase 3. Threshold drops to £20,000. Expected to bring roughly one million additional taxpayers into scope, including most landlords with a single let property.
MTD for Corporation Tax. HMRC has stated its intention but no legislation is in place. Not expected before 2028 at the earliest. Partnerships also remain deferred indefinitely.
What you need to comply
The requirements are the same in principle for both MTD for VAT and MTD for ITSA, though the submission content differs. Here is what every affected business or individual needs.
Compatible software
- Must be on HMRC’s recognised list
- Must connect to HMRC via API
- Must support digital record-keeping
- Spreadsheets need bridging software
Digital records
- All income and expenses recorded digitally
- Digital links between systems
- No manual retyping between tools
- Receipts can still be paper (records must be digital)
Regular submissions
- VAT: quarterly VAT returns
- ITSA: quarterly income/expense summaries
- ITSA: annual Final Declaration by 31 Jan
- All submitted electronically via software
The quarterly submission cycle for ITSA
You can elect to use calendar quarters (starting 1 April) instead of tax year quarters (starting 6 April), which aligns better with VAT quarters for businesses that are both VAT-registered and in scope for ITSA. The election must be made before the first quarterly update is submitted.
Digital record-keeping requirements
The “digital records” requirement is where most of the practical change sits for businesses that have been operating with paper systems or disconnected spreadsheets.
What must be digital
For MTD for VAT, you must keep digital records of: the date, value, and VAT rate of every supply made and received; your own VAT registration number; and the time of supply. These are the same records you’ve always had to keep — they just must now be in digital form.
For MTD for ITSA, you must keep digital records of: all business income (broken down by source), all allowable expenses (categorised appropriately), and the information needed for each quarterly update and the Final Declaration.
What does not need to be digital
Receipts can still be paper
You do not need to scan and store receipts digitally. The underlying evidence — the receipt, the invoice, the bank statement — can remain in paper form. What must be digital is the accounting record derived from that evidence. A paper receipt for a £50 purchase is fine, provided the £50 expense is recorded digitally in your compatible software.
The digital links requirement
Where data moves between different software systems or spreadsheets, the transfer must be electronic. You cannot look at a figure in one spreadsheet and manually type it into another. This is the “digital links” requirement, and it applies to the entire chain from the source transaction through to the HMRC submission.
In practice, this means:
- Exported CSV or API data feeds between systems are acceptable
- Copy-and-paste from one digital system to another is acceptable
- Looking at a screen and retyping the numbers is not acceptable
- All-in-one accounting software (which handles everything internally) satisfies this by default
Bank reconciliation — the process of matching bank transactions against recorded income and expenses — becomes a critical quarterly discipline under MTD. If your books don’t match the bank, the quarterly submission will carry those errors forward. ReconcileIQ is designed specifically for this kind of data matching, working with bank statements and accounting exports from any platform.
The penalty regime
HMRC replaced the old penalty system — fixed fines and default surcharges — with a points-based model. This applies to both MTD for VAT (from January 2023) and MTD for ITSA (from April 2026). It works differently for late submissions and late payments.
Late submission penalties
Points accumulation
Each missed submission deadline earns one penalty point. Points accumulate across all obligation types.
The threshold: 4 points
For quarterly obligations, the threshold is 4 points. When you hit 4 points: £200 penalty. Each further late submission: another £200.
Clearing points
Points expire after 24 months of clean compliance. Once at the threshold, you need to submit everything on time for a set “period of compliance” before points reset.
Late payment penalties
Payment penalties are steeper
Late payment penalties apply to VAT payments and the Final Declaration payment for ITSA:
- Days 1–15 late: no penalty (but interest runs from day 1 at Bank of England base rate + 2.5%)
- Days 16–30 late: 3% of the outstanding amount at day 15
- Day 31+: a further 3% of the outstanding amount, plus a daily penalty accruing at 10% per annum until paid
The first-year concession for ITSA
Soft landing for 2026/27
For taxpayers joining MTD ITSA in April 2026, no penalty points will be charged for the first four quarterly updates in the 2026/27 tax year. This gives practices a full year to get systems working without submission penalties for teething problems.
However, this does not extend to late payment penalties, which apply from day one. And the grace period is only for the 2026/27 cohort — those joining at the £30,000 threshold in April 2027 will not receive the same concession.
MTD for VAT vs MTD for Income Tax
The two obligations share the same underlying philosophy — digital records, compatible software, electronic submission — but differ in several important ways.
MTD for VAT
Status: Live since April 2019 (all since 2022)
Who: All VAT-registered businesses
Reporting: Periodic (that quarter only)
Content: Nine-box VAT return (output & input tax)
Frequency: Quarterly or monthly
Registration: Automatic via VAT registration
MTD for Income Tax
Status: Goes live April 2026
Who: Sole traders & landlords above threshold
Reporting: Cumulative (year-to-date)
Content: Full income & expense breakdown by category
Frequency: Quarterly + annual Final Declaration
Registration: Separate sign-up required
They are separate obligations
Being signed up for MTD for VAT does not automatically enrol you for MTD ITSA. They are distinct services with separate registrations, separate software requirements, and separate penalty tracks. A VAT-registered sole trader with qualifying income above £50,000 will need to comply with both, filing quarterly VAT returns and quarterly income/expense summaries. That is potentially eight submissions per quarter for a self-employed VAT-registered individual.
How to stay compliant with software
HMRC maintains a list of compatible software providers for both MTD for VAT and MTD for ITSA. The list runs to hundreds of products, from major accounting platforms to specialist tools for landlords and micro-businesses.
What the software must do
- Keep digital records — store transaction-level data in the format HMRC requires
- Submit to HMRC via API — transmit the return or quarterly update electronically, directly from the software
- Maintain digital links — ensure data flows digitally from source to submission without manual retyping
- Support the required return type — VAT nine-box return for MTD VAT, income/expense categories for MTD ITSA
The major UK accounting platforms — Xero, QuickBooks, Sage, FreeAgent, Pandle — all support MTD for VAT and are building or have built MTD ITSA support. Most handle the submission process with a few clicks once the records are up to date.
Where the real challenge sits
The software itself is not usually the bottleneck. The bottleneck is keeping the records accurate and up-to-date so the software has correct data to submit. For businesses already doing monthly bookkeeping, the transition to quarterly reporting is minor. For businesses that currently reconstruct a full year from bank statements every January, the change is seismic.
This is where the practical workflow matters more than the technology choice:
Bank transactions flow into the system
Whether through a bank feed, CSV import, or manual entry, the raw bank data needs to be in the software. Most platforms offer automatic bank feeds that do this daily.
Transactions are coded to the correct accounts
Each transaction needs to be assigned to the right category in the chart of accounts — office supplies, travel, cost of goods, professional fees, and so on. This is typically the most time-consuming step, especially for businesses with hundreds of monthly transactions. CodeIQ automates this using a seven-layer AI pipeline that learns from the client’s own history and a crowd-sourced pattern database of 3,500+ merchant mappings.
VAT is classified correctly
For VAT-registered businesses, every transaction needs the correct VAT treatment — standard-rated, zero-rated, exempt, reduced rate, or reverse charge. Getting this wrong doesn’t just affect the quarterly ITSA submission — it flows through to the VAT return as well.
Bank reconciliation confirms accuracy
Before submitting, the books should be reconciled to the bank. Every transaction in the software should match a corresponding bank entry. Unmatched items indicate missing transactions, duplicates, or errors. Under MTD, this reconciliation check becomes a quarterly habit rather than an annual one. ReconcileIQ handles this matching automatically across any combination of bank statement and accounting data.
Submission to HMRC
With clean, reconciled records, the quarterly submission itself is straightforward — a few clicks in the compatible software to transmit the summary to HMRC.
For accountancy practices managing dozens or hundreds of clients, the volume challenge is the multiplier. Quarterly reporting for 100 clients is 400 quarterly submissions per year, plus 100 Final Declarations. The practices that will handle this comfortably are the ones automating the bookkeeping itself — the coding, the VAT classification, the reconciliation — not just the submission step.
Quarterly bookkeeping at scale
MTD means reconciling every client’s books every quarter. CodeIQ automates the transaction coding. ReconcileIQ matches bank data to books. LedgerIQ provides the analysis layer. Together, they turn quarterly compliance from a bottleneck into a workflow.

What is Making Tax Digital?
Making Tax Digital (MTD) is HMRC’s programme to move UK tax administration to digital record-keeping and electronic reporting. It requires businesses and individuals to keep records in compatible software and submit tax information to HMRC electronically via API. MTD currently covers VAT (mandatory since 2022) and expands to Income Tax Self Assessment from April 2026.
When does Making Tax Digital for Income Tax start?
MTD for ITSA starts on 6 April 2026 for sole traders and landlords with gross qualifying income above £50,000. The threshold drops to £30,000 from April 2027 and to £20,000 from April 2028. Partnerships have been deferred indefinitely with no confirmed date.
Do I need MTD if I’m VAT registered?
Yes. Since April 2022, all VAT-registered businesses must comply with MTD for VAT, regardless of turnover. If you are also a sole trader or landlord above the ITSA income thresholds, you will need to comply with MTD for Income Tax separately. They are distinct obligations with separate sign-ups and separate penalties.
What software do I need for Making Tax Digital?
You need HMRC-recognised MTD-compatible software that can maintain digital records and submit returns directly to HMRC via their API. Major providers include Xero, QuickBooks, Sage, and FreeAgent. Spreadsheets can be used for record-keeping but must connect through API-enabled bridging software. HMRC publishes a list of compatible software on GOV.UK.
What are the penalties for not complying with MTD?
HMRC uses a points-based system. Each missed deadline earns one penalty point. At 4 points (for quarterly obligations), a £200 fine is charged, then £200 for each further late submission. Late payment penalties are separate and steeper: no charge for the first 15 days, 3% of outstanding at day 16, and a further 3% plus 10% per annum daily interest from day 31. Points expire after 24 months of clean compliance.
Does Making Tax Digital affect limited companies?
MTD for VAT affects all VAT-registered entities, including limited companies. However, MTD for Income Tax only applies to sole traders and landlords — not limited companies. Corporation Tax MTD has no confirmed start date.
What is the difference between MTD for VAT and MTD for Income Tax?
MTD for VAT requires quarterly VAT returns showing output and input tax. MTD for Income Tax requires quarterly summaries of income and expenses plus an annual Final Declaration. VAT submissions are periodic (that quarter only); ITSA submissions are cumulative (year-to-date). They are separate obligations requiring separate software registrations.
Can I use a spreadsheet for Making Tax Digital?
You can use a spreadsheet to keep digital records, but you cannot submit directly from a spreadsheet. You need API-enabled bridging software to connect your spreadsheet to HMRC’s systems. Data must flow digitally from records to submission with no manual retyping. Most accountants recommend dedicated accounting software as the simpler long-term approach.
