HMRC Clarifies Director Tax Return Rules, What the New Close Company Reporting Means
HMRC Clarifies Director Tax Return Rules, What the New Close Company Reporting Means
HMRC has issued clarification on when a limited company director must file a Self Assessment tax return, and how the “close company” rules affect reporting duties. The update matters most for unpaid directors and directors who hold no shares, who often assume the rules do not apply to them. All rates, thresholds and rules in this guide are correct as of 22 September 2026.
Key Takeaways
- Most Ltd companies with 5 or fewer shareholders, or where the directors together control it, are “close companies”.
- Being a director can trigger a Self Assessment filing duty even with no salary, dividend or shareholding.
- Close company status brings extra scrutiny of benefits in kind and P11D reporting.
- Loans to participators can trigger a 33.75% S455 tax charge for the company if not repaid in time.
- Missing the Self Assessment deadline brings automatic penalties, even if no tax is owed.
What is a close company?
As of 22 September 2026, a company is broadly treated as a close company where it is controlled by five or fewer shareholders, or where it is controlled by any number of directors who are also shareholders (called “participators”). Most owner-managed Ltd companies in the UK fall into this category, including single-director companies and small family businesses.
Why close company status matters
Close company rules exist because HMRC treats these businesses as closely connected to the individuals who run them. That connection brings extra reporting duties around director loans, benefits in kind and, in some cases, distributions, that do not apply in the same way to larger, widely held companies.
Who must file a Self Assessment return as a director
HMRC's clarification confirms that being appointed as a company director can, on its own, create a duty to register for Self Assessment and file a personal tax return, regardless of whether you take a salary, dividend or any other income from the company. This surprises many small business owners who assumed no pay meant no filing obligation.
In practice, HMRC has said it will not usually require a return solely because someone is a director if they have no other reason to file, such as untaxed income, and their only PAYE income is fully taxed at source. However, directors of close companies, and directors who receive dividends, benefits in kind, or any untaxed income, are expected to register and file. If in doubt, it is safer to check your position rather than assume you are excluded.
Don't assume you're exempt
“I don't take any money out of the company” is not the same as “I have no filing duty”. Directors without a shareholding, and unpaid directors, should still confirm their position with HMRC or a qualified adviser as of 22 September 2026.
Unpaid directors and directors without a shareholding
The clarification specifically addresses two groups who often fall through the gaps:
- Unpaid directors: those who take no salary, dividend or benefit from the company. HMRC's position is that a filing duty is less likely where there is genuinely no income and no other reportable factor, but this should be confirmed each tax year rather than assumed to continue indefinitely.
- Directors without a shareholding: non-shareholder directors, such as some family members or professional directors appointed for governance reasons, are not automatically exempt. Their obligation depends on whether they receive taxable income or benefits, not on whether they hold shares.
The safest approach for both groups is to review their position with each new tax year, particularly if their role, pay or benefits change, or if the company's close company status changes.
P11D and benefit-in-kind reporting for close companies
Close companies face particular attention around benefits in kind provided to directors and their families. Company cars, private medical insurance, low-interest or interest-free loans, and other non-cash benefits generally need to be reported on a P11D, with Class 1A National Insurance paid by the company. As of 22 September 2026, employers should also be aware that mandatory payrolling of most benefits in kind is being phased in, with full mandation planned from April 2027; this remains a proposal timeline directors should watch rather than a rule already in force.
Loans to participators: when S455 tax applies
Where a close company lends money to a director or other participator (or an associate of theirs) and the loan is not fully repaid within nine months and one day of the end of the accounting period, the company must pay S455 tax on the outstanding balance at 33.75%, as of 22 September 2026. This applies whether or not interest is charged, and applies in addition to any personal benefit-in-kind charge on the director if the loan is interest-free or low-interest and exceeds £10,000 at any point in the tax year.
Good practice for director loan accounts
- Keep the director's loan account up to date and reconciled throughout the year, not just at year end.
- Repay or formally declare a dividend to clear an overdrawn balance before the nine-month deadline.
- Avoid repaying and immediately re-borrowing the same funds, which HMRC may treat as “bed and breakfasting” and disregard for S455 purposes.
- Get advice before treating a directors' loan as a way to extract funds tax-efficiently.
Penalties for missing the filing deadline
As of 22 September 2026, the standard Self Assessment penalty regime applies in full to directors required to file. A return filed even one day after the 31 January deadline attracts an automatic £100 penalty, even where no tax is due. Further daily penalties of £10 apply after three months (up to £900), with additional penalties of the greater of £300 or 5% of the tax due at six and twelve months. Interest also accrues on any unpaid tax from the original due date.
Late filing adds up quickly
A return that is 12 months late, with tax outstanding, can attract penalties well in excess of £1,600 before interest, on top of the tax itself. Directors who believe they should not have to file should still confirm this with HMRC rather than simply not registering.
Practical steps for directors to take now
What to check as of 22 September 2026
- Confirm whether your company meets the close company definition, based on its current shareholders and directors.
- Check your own filing position, especially if you are unpaid, hold no shares, or your circumstances have changed this year.
- Review any director's loan account balance well before the nine-month S455 deadline.
- Make sure benefits in kind are correctly identified and reported on time via P11D.
- Register for Self Assessment promptly if you are unsure, since registering late can itself trigger penalties.
Good bookkeeping throughout the year makes each of these checks far easier, because director's loan movements, benefits and dividends are already recorded accurately rather than reconstructed at year end. Our limited company accounts service includes a review of close company status and director reporting duties as standard, and our personal tax return service covers Self Assessment filing for directors, whether paid, unpaid, or without a shareholding.

Questions directors ask about the new rules
Do I need to file a tax return if I'm a director but take no salary or dividends?
Not necessarily, but you should check. HMRC's clarification confirms that unpaid directors are less likely to need to file if they have no other taxable or untaxed income, but this depends on the company's close status and your specific circumstances, and should be reviewed each tax year rather than assumed.
I'm a director but I don't own any shares, does this affect me?
Your filing duty depends on the income and benefits you receive, not on whether you hold shares. Non-shareholder directors who receive no pay or benefits are less likely to need to file, but should still confirm their position with HMRC or an adviser.
How do I know if my company is a close company?
As of 22 September 2026, a company is generally close if it is controlled by five or fewer shareholders, or by any number of directors who are also shareholders. Most small owner-managed Ltd companies, including single-director companies, meet this definition.
What happens if I don't repay a director's loan in time?
If the loan is not repaid within nine months and one day of the end of the accounting period, the company must pay S455 tax at 33.75% on the outstanding balance, as of 22 September 2026. This is refundable once the loan is later repaid, but the company must fund the tax in the meantime.
Do all benefits in kind need to go on a P11D?
Most non-cash benefits provided to directors, such as company cars, private medical insurance and cheap or interest-free loans over £10,000, need to be reported on a P11D, with Class 1A National Insurance paid by the company. Full mandatory payrolling of benefits is currently proposed for April 2027 but is not yet in force.
What if I've missed the filing deadline already?
File as soon as possible to stop further daily and six-month penalties accruing. An automatic £100 penalty applies even for a return one day late, but earlier filing limits the total penalty and any interest on tax owed.
