HMRC transformation roadmap

By Shamayun Chowdhury, Senior Accountant, Major Accountancy · Published: 5 November 2026 · Last reviewed: November 2026 · Based on HMRC’s 2026 progress update

Most people only notice HMRC’s plans when a letter arrives or a deadline moves. The HMRC transformation roadmap writes those changes down in advance, with dates. If you run a business, let property or act for clients, it shows what is coming before 2030.

The trouble is length. The HMRC transformation roadmap 2026 update runs to tens of thousands of words. This guide pulls out the parts that affect small businesses, landlords and agents, puts them on one timeline, and ends with a checklist of what to do now.

What Is the HMRC Transformation Roadmap?

HMRC published its transformation roadmap in July 2025. It sets out how the department plans to become a “digital first” tax authority by the end of the decade. It is a plan, not a law, although many of the changes it describes are backed by legislation passed separately.

The roadmap groups its work under three headings:

• Day-to-day performance and customer experience: answering calls and letters faster, and moving routine tasks into online accounts and the HMRC app.
• Closing the tax gap: collecting more of the tax that is owed but not paid, using data, more staff and stronger powers.
• Reform and modernisation: replacing old computer systems, expanding Making Tax Digital, introducing e-invoicing and using AI.

This is HMRC digital transformation on a large scale. Behind all three is a simple aim. HMRC wants fewer phone calls and paper forms, and more people and businesses dealing with it online, using software that sends data straight to HMRC.

What Changed in the 2026 Progress Update?

HMRC published its transformation roadmap update 2026 on 2 July 2026 and revised it later that summer. It reports progress against the 2025 promises and adds an annex of planned activities for 2026 to 2027.

The headline progress figures for 2025 to 2026 were:

• 78% of customer interactions were digital, up from about 65% in 2020 to 2021.
• The HMRC app had 7.6 million users, against a target of 10 million by March 2027.
• More than 8 in 10 calls were answered.
• More than 350,000 businesses and landlords had signed up for Making Tax Digital for Income Tax.
• The tax gap for 2024 to 2025 was 6.4%, or £59.2 billion.

The update also admits what slipped: an online expenses service, Child Benefit claim tracking and joined-up handling of letters and penalties missed their 2025 to 2026 targets and are now in progress.

The HMRC Transformation Roadmap Timeline: 2025 to 2030

This is the part most guides leave out. The table lists, in date order, the HMRC transformation roadmap milestones that matter most to small businesses, landlords and agents, taken from the roadmap, the 2026 update and its annex.

Dates can move, and some depend on legislation that is not yet in place. If your business is close to an MTD threshold, check our guide to HMRC MTD deadlines and whether any Making Tax Digital exemptions apply to you.

HMRC Tax Collection Changes Explained

Searches for HMRC tax collection changes and HMRC tax changes 2026 have grown, often driven by worrying headlines. In reality, the roadmap describes a steady tightening of collection rather than one dramatic power. There are four strands.

1. Higher interest and penalties

From 6 April 2025, late payment interest on most taxes rose to the Bank of England base rate plus 4%. VAT late payment penalties also increased. Paying late now costs noticeably more than it did, which is why HMRC encourages early contact and Time to Pay arrangements. Our guide to VAT payment dates shows the current VAT penalty rates.

2. More data and “nudges”

HMRC is collecting more information from third parties and using it before you file. VAT data nudges, which prompt businesses to check figures that look out of line, are due to widen from April 2027. From the 2027 to 2028 tax year, new reporting rules on financial accounts and card sales give HMRC more data to match against returns.

By 2028, HMRC plans to pre-fill parts of Self Assessment returns with third-party data. The idea is to prevent errors rather than chase them later. For honest taxpayers, the practical effect is fewer surprises, as long as your records match what banks and platforms report.

3. Debt recovery

HMRC has kept around 1,200 debt management staff and is recruiting more. For 2026 to 2027, it aims to collect £22 million by directly recovering debts from people and companies who can pay but refuse, and £31 million of older debts through private debt collection agencies.

Following a consultation, the government published its response on lower-value tax debts on 28 October 2026. It confirmed it intends to develop the policy further, with strengthened safeguards. The proposed approach would allow affordable, regular deductions from bank accounts in certain cases where people repeatedly fail to engage despite being able to pay. This is not yet law.

4. More compliance officers

HMRC aims to reach 5,500 extra compliance officers by 2029 to 2030, with 1,100 recruited in 2026 to 2027. It also plans at least 30,000 high-street-linked interventions in 2026 to 2027, working with other agencies to tackle illegal business activity and related risks, including tax evasion, illicit tobacco, alcohol and vapes, National Minimum Wage breaches and anti-money laundering failures.

Proposed HMRC Tax Enforcement Changes to Watch

Several proposed HMRC tax enforcement changes are still at consultation or design stage. They are not yet law in their final form, but they show the direction of travel:

• Penalty reform: simpler rules for inaccuracy and failure-to-notify penalties.
• A duty to correct errors: a planned obligation for taxpayers to put right mistakes they find in past returns.
• Umbrella company PAYE: responsibility for PAYE shifting to recruitment agencies or end clients where umbrella companies are used.
• Digital Disclosure Service: a self-serve way to tell HMRC about unpaid tax and pay it, due to go live in 2027 to 2028.
• More timely payments: a consultation on bringing Self Assessment payments closer to when income is earned, with more regular in-year payments from April 2029 for taxpayers who currently make payments on account.
• Tougher action on advisers: stronger powers against advisers who deliberately help clients not comply, which applied from 1 April 2026.

What the Roadmap Means for You

The same plan affects different taxpayers in different ways. Find the group that matches you.

Sole traders and landlords

Making Tax Digital for Income Tax is the biggest change. If your qualifying income from self-employment and property is over £50,000, you have been in since April 2026, with your first quarterly update due on 7 August 2026. The qualifying income threshold falls to £30,000 in April 2027 and £20,000 in April 2028.

You will need software that keeps digital records and sends quarterly updates. The HMRC app and your online account are becoming the main way to check what you owe and pay it.

VAT-registered businesses

Around 2 million businesses already use MTD for VAT. Over the next few years, expect a VAT repayments tracker, a smoother registration process, more data nudges from April 2027 and, from 1 April 2029, mandatory e-invoicing.

What does mandatory VAT e-invoicing mean for your business?

The government published its e-invoicing implementation roadmap on 28 October 2026. From 1 April 2029, VAT-registered businesses will generally need to issue VAT invoices as e-invoices and be able to receive them, subject to specific exemptions. The detailed scope, technical standards and exemptions will be confirmed ahead of implementation, so treat today’s details as provisional. HMRC’s e-invoicing requirements page sets out what is known so far.

• An e-invoice is not a PDF. It is created and exchanged as structured digital data, so the buyer’s system can read it automatically. A PDF, Word file or scanned image sent by email will not count.
• Peppol is the core framework. Invoices will travel between businesses through certified Peppol access points, usually provided by your accounting software.
• Both sides need to be ready. In-scope businesses will need to send VAT invoices as e-invoices and be able to receive them from suppliers.
• The VAT rules themselves stay the same. What changes is the format and route of the invoice, not what must appear on it.

If your software cannot send or receive e-invoices yet, ask your provider now about its Peppol plans and timetable.

Limited companies

HMRC is replacing its old Corporation Tax computer system, with completion due in 2028. More than 10 million businesses now use the business tax account. Companies registered for VAT should also plan for e-invoicing.

Agents and accountants

Agents saw some of the earliest changes. HMRC’s new mandatory tax adviser registration began on 18 May 2026 and is being introduced in phases up to 31 March 2027, with different registration windows for different adviser groups. Check which window applies to you.

Multi-factor authentication for advisers is due by the end of 2026 to 2027. Customers can now authorise more than one agent for MTD for Income Tax, with a similar VAT option planned.

A plan for working with the software industry is due in April 2027, and agents are expected to move to One Login by 2030. Our guide to the HMRC agent services account covers how client access works today.

Digital by Default, the HMRC App and HMRC One Login

HMRC’s digital-by-default legislation lets it send correspondence digitally to customers who use its online services, unless they opt out and choose paper. Digitally excluded customers will still get paper letters, and the change is happening gradually as each service becomes ready. HMRC expects paper post to fall by about 75%, saving £50 million a year by 2028 to 2029. Our guide to HMRC digital letters explains how to find and check them.

The HMRC app is central to the plan. In January 2026, people paid £818.8 million of Self Assessment tax through it, up from £499 million a year earlier. GOV.UK One Login is replacing Government Gateway. New individual customers already use it, and HMRC is preparing to move existing individuals from 2026 to 2027 onwards, with agents and organisations later and all customer groups by 2030.

HMRC Tax System Modernisation: Technology and AI

Much of the HMRC tax system modernisation work happens out of sight. HMRC says more than half of its services have been moved to the cloud or switched off, and it is building new customer relationship and contact centre platforms.

• AI: more than 28,000 Microsoft Copilot licences were issued to staff by March 2026, rising to 50,000 during 2026. An “Ask HMRC” digital assistant handled over 6.3 million interactions in 2025 to 2026.
• Customs: the Customs Declaration Service handled more than £1 trillion of goods trade in 2024 to 2025. Digital ATA Carnets started on 1 June 2026, and the online Trade Tariff is being redesigned.
• Forms: more than 100 paper forms are being reviewed for digitisation, and Inheritance Tax is due to go digital from 2027 to 2028.

For traders, this is the HMRC tax customs system transformation roadmap in practice: fewer paper processes, more data exchanged automatically, and more checks done by systems before a person looks at a case.

What to Do Now: An 8-Point Checklist

1. Work out your qualifying income and when MTD for Income Tax applies to you.
2. Choose MTD-compatible software well before your start date.
3. Keep business and personal spending separate, so third-party data matches your records.
4. Download the HMRC app and check your online account at least once a quarter.
5. Update your email address and contact details with HMRC so digital letters reach you.
6. If you are an agent, confirm your tax adviser registration and set up multi-factor authentication.
7. If you are VAT-registered, ask your software provider about e-invoicing plans for 2029.
8. If you owe tax you cannot pay, contact HMRC early rather than waiting for collection action.

Is the HMRC Transformation Roadmap on Track?

Partly. HMRC hit several targets, including digital use, call answering and record compliance yield of £48 billion in 2024 to 2025. Some services slipped, and some stakeholders remain unconvinced.

In July 2026, ICAEW said HMRC was making slow progress on problems agents face every day, such as reaching the right person and fixing client records. That matters because many of the roadmap’s digital gains depend on agents being able to work smoothly on clients’ behalf.
