HMRC have published their Agent Update for July 2026. We have summarised the key content, including the phased introduction of mandatory payrolling of Benefits In Kind (BIKs), changes to the taxation of carried interest and voluntary National Insurance Contributions (NICs), the launch of the Advance Tax Certainty Service, Making Tax Digital (MTD) developments, and a range of compliance deadlines and agent service updates.
Tax adviser registration: check if you need to register by 18 August
Mandatory tax adviser registration is now open.
- The requirement to register is being rolled out in phases.
If your firm submits returns, makes payments or communicates with HMRC on behalf of clients, you must register for an agent services account by 18 August 2026, unless one of the following applies:
- If you already have a Self Assessment or Corporation Tax account, you will need to register from 18 August 2026.
- If you only provide third-party payroll services on behalf of clients and do not interact with HMRC in any other way, you will need to register from 18 November 2026.
- If you are a financial services organisation, you will need to register from 31 December 2026.
Use HMRC's checker tool and guidance to check if and when you need to register as a tax adviser with HMRC.
- You can use the online service to register now, even if you are not required to do so until a later date.
If you already have an agent services account, no immediate action is required.
- HMRC will contact you through your account if any further information is required.
HMRC say that mandatory tax adviser registration will help create a fairer market for taxpayers and advisers through a single, streamlined digital system.
Tax adviser registration is only intended to apply where there is a genuine third-party advisory relationship.
- In-house tax teams and advice provided across corporate groups are already out of the scope of the new rules. HMRC recognise similar structures where there is no genuine third-party advisory relationship and do not intend that those businesses should register.
- These structures include:
- Joint ventures.
- Investment structures, including real estate investment trusts and managed funds.
- Special purpose vehicles and their sponsoring firm.
- Partnership models with multiple Limited Liability Partnerships (LLPs).
- Trusts and their trustees.
- Transitional advice during mergers and acquisitions and similar.
Businesses relying on HMRC guidance in good faith to decide that they do not need to register will be treated as compliant, with no sanctions or penalties, even if HMRC later clarify that the business should register.
- HMRC will support businesses to comply within a reasonable timeframe.
Further clarification will be provided in guidance.

Self Assessment payment on account deadline 31 July: remind your clients
The second Self Assessment payment on account is due by 31 July 2026.
- Remind clients now to avoid interest charges.
- You can direct your clients to pay their Self Assessment bill online.
What clients should do now:
- Check what's due and pay by 31 July 2026.
- Make plans if they are unable to pay in full.
- They may be able to set up a Time to Pay arrangement online.
- Review payments on account if their income has fallen.
- You can help them apply to reduce them to avoid overpaying.
Helpful information you can share with clients:
- Payments on account are advance payments towards the next tax bill, usually due in two instalments: 31 January and 31 July.
- Each payment is typically 50% of the previous year's tax bill, excluding Capital Gains Tax (CGT) and student loan repayments.
- If their tax bill was under £1,000 or more than 80% was collected at source, they may not need to make payments on account.
A short, timely prompt from agents will help increase on-time payments.
See Payments On Account (POAs): Self Assessment
Mandatory payrolling of Benefits In Kind (BIKs) to launch in phases
Following extensive engagement with employers, payroll software developers and representative bodies, the government has decided to phase in the introduction of mandatory payrolling of BIKs from April 2027.
- From 6 April 2027 to 5 April 2028, mandatory payrolling will apply only to:
- Company cars.
- Car fuel.
- Vans.
- Van fuel.
- Medical benefits.
- Mandatory payrolling for most other benefits will be introduced from April 2028.
- HMRC say that phasing delivery in this way will support employers and payroll providers to prepare and adapt in a manageable way.
Employers will be able to register for voluntary payrolling from November 2026 for all other BIKs that have not been mandated to be payrolled from April 2027, including loans and accommodation.
- HMRC are considering expanding the voluntary service to allow for payrolling of Class 1A National Insurance Contributions (NICs).
- Further information will be provided in future Agent Updates.
HMRC have updated their interim guidance to reflect phasing and feedback received to date.
- HMRC expect the final guidance for phase 1 to be published in Autumn 2026.
Check out the Making Tax Digital (MTD) for Income Tax special edition
The first quarterly update deadline for MTD for Income Tax is 7 August 2026. On 7 July 2026, HMRC published an MTD for Income Tax special edition of the Agent Update, which contains some practical steps and further support to help you and your clients meet the first submission deadline.
The special edition also includes:
- Videos and signposting to helpful guidance, such as the software finder tool and agent toolkit.
- Top tips from agents.
- Where to go for general support.
See Agent Update: Making Tax Digital for Income Tax
Student loans within MTD
MTD software will hold details of your client's student loan plan type, postgraduate loan or both, using information that the Student Loans Company shared with HMRC.
- Quarterly updates calculate an estimate of student, postgraduate loan or both repayments based on your client's income and the applicable thresholds at that time.
- These estimates are not payable.
After the fourth quarterly update, you must submit a tax return.
- MTD software will calculate the actual student or postgraduate loan charge on the tax return using the applicable annual threshold.
- This replaces the estimates from the quarterly updates.
- This final amount is included in your client's tax liability, which is due to be paid by 31 January following the end of the tax year and sent to the Student Loans Company.
If your client has PAYE employment and had a PAYE student, postgraduate loan or both, deductions taken by their employer for these amounts are pre-populated and offset against the quarterly estimate and the final amount.
Multi-Factor Authentication (MFA): do not miss the chance to activate early
If you missed the first deadline, there is still an opportunity to request an early activation for MFA.
The introduction of MFA brings agent accounts in line with the protection already in place for individual and organisation government gateway accounts and is part of HMRC's ongoing work to protect agents and their clients from the evolving threat to online security.
Agents can still choose a specific date for MFA to be activated on their account.
- Choosing an early date means you stay in control of when the change happens and benefit from the enhanced security MFA provides sooner.
- To take advantage of this, complete the online form available when signing in to either an agent services account or an HMRC online services for agents account.
- The form will not appear on accounts when MFA has already been activated.
- If you choose to have MFA activated on 19 August 2026, you must submit a form to HMRC by 11:59 p.m. on 31 July 2026.
- Once activated, MFA will be applied to all accounts held under the agent identifier (ID) provided.
- Agents with multiple IDs can choose which ones to activate for this deadline.
Any remaining agent IDs not activated on 19 August will automatically be included in the final activation window of 28 September 2026 to 15 October 2026.
- HMRC are unable to give a specific date within this period to agents who are part of this financial group.
- If you are not planning to have MFA activated before this date, you should use the time between now and September to ensure you are fully prepared.
- HMRC strongly encourage all agents to prepare in advance for their chosen activation date by selecting their preferred future settings and checking for any existing MFA settings that may be outdated.
Full guidance on how to prepare, including information on administrator roles, access code methods, and the 'remember me' function, is available in the Tax Agent's Handbook.

Corporation Tax late filing penalties: reminder on temporary delay to notices
From 1 April 2026, late-filing penalties for Corporation Tax increased.
To ensure the correct amounts are used, HMRC have been updating the Corporation Tax system.
- The system updates, which were originally expected to be completed by 30 June 2026, are now expected to be completed by the end of July.
- Until then, HMRC have paused issuing automatic notices, so taxpayers do not receive penalty letters showing incorrect amounts.
Companies that file a return after the deadline will still be charged a penalty and further penalties may apply if the return remains outstanding.
Make your clients aware that they:
- Should continue to file their Corporation Tax returns on time to avoid penalties at the increased rate.
- May receive a penalty notice later than usual if they file late.
- A delayed notice does not mean no penalty applies.
- Do not need to contact HMRC if they have not received a penalty notice but believe one is due.
- Notices will be issued automatically from late July.
HMRC will provide updates through future Agent Updates and other appropriate channels when the system has been updated and they have resumed issuing automatic notices.
Government consultation on proposals to tackle lower value tax debts
As part of the tax update package announced on 23 June 2026, the government launched a consultation on proposals to tackle lower value tax debts from taxpayers who can afford to pay but persistently choose not to engage with HMRC.
- The proposals would extend an existing HMRC enforcement power, enabling HMRC to recover these debts through affordable monthly deductions from a taxpayer's UK bank or building society account.
The consultation outlines a proposed process and stringent safeguards, and HMRC would welcome industry insight and feedback that will help to inform the policy's development.
The consultation closes on 28 August 2026.
See Consultation on tackling lower-value tax debts
Modernising the distributions framework: consultation published
The government has published a consultation on modernising the taxation of distributions and repayments of capital from companies.
- The consultation opened on 23 June 2026 and will close on 14 September 2026.
The government is exploring proposals to reform several areas of the current legislation, bringing it more into line with current commercial practice, such as:
- A review of the tax treatment of 'new consideration' and 'repayments of capital' in certain scenarios.
- Aligning the taxation of distributions from non-UK resident companies with that of distributions from UK resident companies.
- A review of the interaction of the distributions regime with the loans to participators regime, and how the loans to participators regime might be extended to cover loans received from non-UK resident companies.
- Proposals for the reform of the demergers provisions, the Purchase of Own Shares (POS) relief, and the Transactions In Securities (TiS) rules.
The government is keen to hear stakeholders' views. It welcomes responses from across the agent community who are involved in advising clients on the taxation of distributions and repayments of capital.
Discussions with officials will take place during the consultation period.
- If you would like to be involved, contact HMRC by emailing

Capital Gains Tax (CGT): carried interest
Carried interest is a performance-related reward received by investment fund managers.
- From 6 April 2025, the rate of CGT on carried interest increased from 28% to 32%.
Carried interest, other than income-based carried interest, needs to be declared as a capital gain on the SA108 section of the individual's tax return for the tax year 2025-26.
As announced at Budget 2024, a new tax regime will apply to individuals receiving carried interest from 6 April 2026.
- Under the new regime, all carried interest will be taxed as trading profits, regardless of its underlying source.
- This means carried interest will be subject to Income tax and, where applicable, Class 4 NICs.
HMRC will publish further guidance on how to declare carried interest as trading profits for 2026-27 later this year.
The revised tax regime will apply where an individual performs investment management services directly or indirectly in respect of an investment scheme and carried interest arises to the individual.
- From 6 April 2026, the individual will be treated as carrying on a trade and the carried interest, less any permitted deductions, is treated as the profits of that trade.
Affected individuals may need to consider the impacts on their Self Assessment payments on account.
See Carried interest
Voluntary NICs for periods abroad
From 6 April 2026, for tax years 2026-27 onwards, the option to pay voluntary Class 2 NICs for periods abroad has been removed.
- New Class 3 NICs applications for periods abroad will require 10 years of continuous UK residency, or at least 10 years of paid NICs.
If you have clients who work abroad, inform them of the changes that came into effect from April 2026.
If your clients currently pay Class 2 NICs abroad:
- HMRC will write to them in July or August 2026 if they are affected.
- If they pay by Direct Debit, they should not cancel it.
- HMRC will collect their final payment for the 2025-26 tax year on 10 July 2026.
The changes do not affect anyone's ability to purchase voluntary Class 2 NICs for tax years before 2026-27.
HMRC encourage employers to review the latest guidance on:
- Voluntary NICs for periods abroad from April 2026.
- The tax impact and information note detailing the changes.
The changes are being made to ensure that individuals building a State Pension from outside the UK have a sufficient link to the UK and are paying a fairer price to do so.

Winter payment recovery and opt out
HMRC will recover payment through the tax system for individuals who have a total income of over £35,000 and receive either:
- Winter Fuel Payments in England, Wales and Northern Ireland.
- Pension Age Winter Heating Payment in Scotland.
For PAYE taxpayers, winter payments received in the 2025-26 tax year are currently being recovered through taxpayers' tax codes during the 2026-27 tax year.
- For Self Assessment taxpayers, HMRC will collect their payment through their tax return for 2025-26.
- For online filers, HMRC will include the winter payment on their Self Assessment return where possible, which is due by 31 January 2027.
- Taxpayers should check their winter payment is on their online return and, if not, they should include it themselves.
- Paper filers will need to include it on their return, which is due by 31 October 2026.
Opting out of future payments:
- Anyone who expects their total individual income to be over £35,000 from their private pension, state pension and other sources can opt out of future payments rather than have HMRC take steps to recover it.
- There is a calculator to help taxpayers work out if their total income will be over £35,000 and if HMRC will take back the winter payment.
- Taxpayers should not contact HMRC to opt out of future winter payments.
- Taxpayers in England, Wales and Northern Ireland can contact the Department of Work and Pensions (DWP) to opt out of receiving Winter Fuel Payments or report a change of circumstance.
- Taxpayers who live in Scotland opt out of receiving future Pension Age Winter Heating Payments on the mygov.scot website.
See Winter Fuel Payment recovery
UK-India Double Contributions Convention (DCC)
The UK-India DCC came into force on 15 July 2026.
- The UK and India have agreed to extend the detached worker provision in the DCC from three to five years.
- This means that employees who are sent to work temporarily in India for up to five years, and their employers, will continue to pay NICs in the UK. They will not have to pay social security contributions into the Indian scheme.
- Similarly, employees sent to work temporarily in the UK by their Indian employer for up to five years will continue to pay social security contributions into the Indian scheme so long as they hold a valid certificate issued by the Indian Employees' Provident Fund Organisation. They will not have to pay UK NICs.
- Employees who will remain liable to pay NICs whilst working in India should have a valid certificate of coverage issued by HMRC covering the period of their work in India.
- This confirms to the Indian Employees' Provident Fund Organisation that the employee is not liable to pay social security contributions in India.
- Applications for certificates of coverage for periods of work in India can now be made using the online CA9107 form.

HMRC launch Advance Tax Certainty Service for major investment projects
A first-of-its-kind service for the UK has been launched to provide tax certainty to businesses planning to invest in major projects.
- The Advance Tax Certainty Service, launched by HMRC, provides clarity on how UK tax rules will apply to major investment projects before investor commitment.
Businesses planning to invest £1 billion or more in qualifying UK expenditure over a project's lifetime will now be eligible to apply for certainty on key tax issues.
- This assurance will help them to invest with confidence in the UK.
The service covers the following UK taxes and schemes:
- Corporation Tax.
- VAT.
- Stamp Duty Land Tax.
- Income Tax.
- PAYE regulations.
- Construction Industry Scheme.
Vaping Products Duty (VPD) and Vaping Duty Stamps (VDS) scheme: apply for or amend approvals by 31 July 2026
If your clients are involved in the manufacture of vaping products or are an approved customs or excise warehousekeeper, they need to be ready for VPD and the VDS scheme being introduced by the government on 1 October 2026.
- VPD will be charged at a flat rate of £2.20 per 10ml.
- This will apply to all vaping liquids, including nicotine-free products.
- All vaping products released onto the UK market from this date must carry a duty stamp.
Your clients must ensure they have the right approval in place from 1 October 2026 if they want to produce vaping products or store them in duty suspense from this date.
If your clients are manufacturers, they must apply for approval if they want to:
- Manufacture vaping products in the UK.
- Store vaping products without payment of duty, under duty suspension.
- Purchase or affix VDS.
Each business must be individually approved.
- Group applications covering more than one business will not be approved.
- Your clients can apply for approval to the VPD and the VDS scheme.
If your clients manufacture vaping products after 1 October 2026 without approval, they may receive penalties of up to £10,000 or be subject to criminal prosecution, potentially leading to prison sentences.
Customs warehousekeepers
To store vaping products from 1 October 2026, your clients must make sure their approval covers both:
- The storage of vaping products.
- Excise goods.
If your clients already have an approval to store excise goods, they will need to amend this to cover vaping products. This will not happen automatically.
- Your client should contact their supervising office as soon as possible to do this.
- They can find the contact details for their supervising office on their customs warehousing authorisation letter.
Excise warehousekeepers
To store vaping products from 1 October 2026, your clients will need to apply to amend their approval to cover vaping products.
- Your clients can apply to add, remove or change a warehouse as an authorised excise warehousekeeper.
If your clients do not have approval, they will not be able to legally store duty-suspended vaping products in the UK after this date. This may disrupt their business operations.
- If your clients do store them without approval, their warehousekeeping approval may be at risk, and they could receive criminal and civil penalties, including potential prison sentences.
If your clients need a new approval or need to amend an existing approval, they should apply by 31 July 2026.
HMRC carry out robust checks on applications, which can take more than 45 working days to process.
- If your clients do not apply by 31 July 2026, it is unlikely they will get approval by 1 October 2026.
Reporting suspicious activity in an HMRC online account
Agents can report suspicious activity in their own or their clients' HMRC online account using a reporting tool on GOV.UK.
- This makes it quicker and easier to tell HMRC about activity that does not look right at a time that suits you.
Suspicious activity could include:
- Being locked out of an account because details have changed.
- Changes to tax records not made by you or your client.
- Unexpected letters or payments from HMRC.
This could be a sign someone has used personal information to access an HMRC account without permission. When you report suspicious activity in an HMRC online account, they will investigate and contact you or your client, with the outcome and any action you need to take.
Agents who have MFA can also report suspicious activity directly in their online account following these steps:
- Sign in to your agent services account.
- Select 'Manage account'.
- Select 'View or change your sign in and security details'.
If you or your client uses third-party software, HMRC also recommend you check it for any suspicious activity, such as changes to bank details.
You can find guidance on reducing fraud risk on the online security information for agents.
