SME Accounting News & Deep Dives: Close Company Reporting Looms, Companies House iXBRL Overhaul & MTD Auto-Enrolment

Limited-company accounting support for growing SMEs starts at £300 inc VAT.

Wednesday 26 August 2026 | Author: Jessica

This week’s SME accounting news points to one clear direction: better records, more digital reporting and closer scrutiny of the money moving between companies and their owners.

HMRC is considering new close-company reporting requirements. Companies House has confirmed that annual accounts will move to software-only iXBRL filing from April 2028. Meanwhile, Making Tax Digital (MTD) for Income Tax has reached its first major deadline, with HMRC preparing to auto-enrol taxpayers who have not taken action.

For limited companies and growing SMEs, the message is not to panic. It is to start improving records and planning decisions before they become urgent.

1. HMRC close-company reporting: why director loan accounts matter

HMRC’s consultation on reporting company payments to participators ran from 19 March to 10 June 2026. A government response is expected to be considered around the 28 October 2026 Budget, although the final design and timetable have not yet been confirmed.

Read the HMRC close-company reporting consultation.

What is a close company?

A close company is broadly a company controlled by:

• Five or fewer participators, or

• Any number of participators who are also directors.

A participator is usually someone with an interest in the company’s capital or income, such as a shareholder.

That means most owner-managed limited companies and family-run businesses are likely to be close companies.

What information could HMRC require?

The consultation proposes that close companies may need to report more detailed information about transactions with participators. This could include:

• Director’s loan account movements

• Cash withdrawals and payments

• Loans and other debts

• Dividends and distributions

• Transfers of assets to or from the company

• Loan repayments, releases and write-offs

• Other transfers of value not already reported as employment income

The information could include the recipient, transaction date and amount or value.

Market commentary has referred to a possible new CT600 supplementary form, provisionally described as CT600C. However, HMRC has not confirmed that name or finalised the form. At present, close-company loan reporting remains connected with the existing CT600A process.

Why is this important?

In many small companies, business and personal finances can become mixed. A director may pay for a personal item from the company bank account, take money out temporarily or use the director’s loan account to draw funds before profits are formally distributed.

These transactions are not automatically wrong, but they must be recorded and dealt with correctly.

A director’s loan account that remains overdrawn can create:

• A potential section 455 Corporation Tax charge for the company

• A personal tax charge if a loan is released or written off

• Additional reporting requirements

• Cash-flow problems if the company cannot repay the charge promptly

The proposed reporting framework would give HMRC a clearer picture of how value moves between close companies and their owners.

What should directors do now?

Before any new rules arrive, limited-company directors should:

1. Reconcile the director’s loan account regularly.

2. Keep separate records for salary, dividends, expenses and loans.

3. Record the date and purpose of personal payments made by the company.

4. Prepare dividend paperwork, including board minutes and dividend vouchers.

5. Review related-party transactions, including asset transfers and company-paid personal costs.

6. Ask a corporation tax accountant to check whether any loan charge or personal reporting is required.

Clear records are likely to be the best protection against confusion, errors and avoidable HMRC enquiries.

2. Companies House accounts overhaul: iXBRL becomes the standard

Companies House has confirmed that its accounts reforms will take effect from 1 April 2028, giving companies more time to prepare.

From that date:

• All UK companies will file annual accounts using commercial software.

• Accounts will need to be submitted in iXBRL format.

• Web and paper filing routes for accounts will close.

• Small companies and micro-entities will need to file profit and loss accounts.

• The option to file abridged accounts will be removed.

• Audit exemption statements will be strengthened.

The Companies House announcement on accounts filing reforms confirms that small companies and micro-entities will be able to opt out of putting their profit and loss figures on the public register. However, Companies House, HMRC and law enforcement will still be able to access the information.

This creates an important distinction: businesses may have more privacy over public disclosure, but they will still need to produce accurate and complete accounts.

What does iXBRL mean for SMEs?

iXBRL is a structured digital format that allows financial information to be read by both people and software.

For a growing company, the practical consequences may include:

• Choosing compatible accounts production software

• Keeping cleaner digital bookkeeping records

• Checking that accounts and reports are submitted together

• Reviewing how profit and loss information is presented

• Planning for software and adviser costs

Director and PSC identity verification is already mandatory under the wider Companies House reforms. Presenter and Authorised Corporate Service Provider requirements are expected no earlier than November 2027, with at least six months’ notice before implementation.

Web filing will continue for non-accounts submissions such as confirmation statements and director updates.

Companies should not wait until 2028 to ask whether their current software or accountant can handle the change. A short review now can prevent a rushed transition later.

3. MTD for Income Tax reaches its first major milestone

MTD for Income Tax is aimed at sole traders and landlords, rather than limited companies. However, it matters to growing businesses considering whether to incorporate.

HMRC reports that:

• More than 436,000 sole traders and landlords submitted their first quarterly update by 7 August 2026.

• More than 570,000 customers have signed up.

• HMRC will begin auto-enrolling eligible taxpayers from September 2026.

• The qualifying income threshold falls to £30,000 from April 2027.

The HMRC update on the first MTD quarterly submissions confirms that quarterly updates do not replace the annual Self Assessment tax return.

There are no penalty points for late quarterly updates during 2026/27, but digital record-keeping is still mandatory. From 6 April 2027, points-based penalties will apply. A taxpayer can receive one point for each missed quarterly deadline, with a £200 fixed penalty once four points are reached.

For sole traders who are considering incorporation, MTD may be a reason to review their structure, but it should not be the only reason.

4. Deep dive: should a sole trader incorporate?

Surveys suggest that around 23% of sole traders within scope have started incorporating, while 57% have explored the option. These figures should be treated as survey findings rather than official national statistics.

The important point is that MTD does not force a sole trader to become a limited company.

Potential advantages of incorporation

A limited company may offer:

• Limited liability, subject to the usual legal exceptions

• Corporation Tax treatment

• Flexibility over salary and dividend extraction

• A structure that may suit external investment

• Greater separation between business and personal finances

• Potential advantages for reinvestment and long-term growth

The additional responsibilities

A company also brings extra obligations, including:

• Statutory accounts

• Corporation Tax calculations and CT600 filing

• Companies House filing requirements

• Payroll and RTI reporting where directors or staff are paid

• Dividend paperwork

• Company bank account and bookkeeping controls

• Potential close-company reporting

• More software, compliance and professional costs

Companies continue to file Corporation Tax broadly as they do now. MTD for Corporation Tax was scrapped, so there is no equivalent quarterly MTD regime for companies. However, companies must use commercial software for Corporation Tax filing, and HMRC’s old online Corporation Tax filing service closed in March 2026.

Model the decision on profit, not MTD avoidance

The right question is not: “How do I avoid MTD?”

It is: “Which structure works best for my actual profit, risk, extraction needs and growth plans?”

A sole trader with modest profits may find the simplicity of remaining unincorporated is more valuable than incorporation. A business with consistently higher profits, employees, commercial risk or plans to retain earnings may benefit from a limited-company structure.

The calculation should include:

• Income Tax and National Insurance

• Corporation Tax

• Dividend tax

• Salary and employer National Insurance

• Accountancy and software fees

• The value of limited liability

• Whether profits will be withdrawn or retained

• Future investment and funding plans

A business accountant UK owners can trust should model both structures using real figures rather than relying on a fixed turnover threshold.

Self-Assessment tick-box: [ ] If you are a company director, shareholder, sole trader or landlord with personal income outside your salary, check whether you need to include it on your Self Assessment tax return.

5. Budget 2026 planning: keep flexibility

The next Budget is scheduled for 28 October 2026. No one can know the measures until they are announced, but growing companies can still prepare sensibly under current rules.

Review:

• Planned capital expenditure

• Use of the Annual Investment Allowance

• Full expensing for qualifying company investments

• The timing of dividends

• Director salary and bonus levels

• Pension contributions

• Retained profits and cash reserves

• Potential changes to Corporation Tax or dividend taxation

Do not accelerate transactions solely because of speculation. Instead, prepare scenarios.

For example, your company could model:

• Taking a dividend before the Budget

• Retaining cash for investment

• Buying qualifying equipment before the year end

• Paying a bonus where commercially justified

• Delaying a decision until the Budget details are clear

The objective is flexibility. Avoid creating a cash-flow problem today in response to a tax change that may never happen.

Action list for the week

For limited companies and growing SMEs, this week’s practical checklist is:

• Reconcile all director’s loan accounts.

• Review dividends and confirm that supporting paperwork exists.

• Separate personal costs from genuine company expenses.

• Check whether your accounting software supports future digital filing requirements.

• Ask when your accountant expects to move you to iXBRL-compatible workflows.

• Review director and PSC identity verification status.

• Model incorporation using actual profits if you are currently a sole trader.

• Prepare a Budget 2026 scenario covering dividends, remuneration and investment.

• Put 28 October 2026 in your planning calendar.

• Keep personal tax information ready for any director Self Assessment return.
