S.455 Tax Reclaim Using Form L2P: Timing the Refund
S.455 tax is the corporation tax charge that applies when a director or shareholder borrows money from their close company and has not repaid it within nine months of the company's accounting year end. The S.455 tax rate increased to 35.75% starting April 2026. Following statutory alignment with the higher dividend tax rate for the 2026/27 tax year, the rate for loans made on or after 6 April 2026 is 35.75%. The 33.75% rate only applies historically to loans issued between April 2022 and April 2026.
A company with a 31 March 2026 year end has until 1 January 2027 to clear the loan before the charge crystallises. If the loan is still outstanding on that date, s.455 tax is due alongside the corporation tax payment.
That charge is not permanent. HMRC holds the money until you repay the loan (or write it off, or convert it to a dividend), at which point the company can reclaim it.
How to Reclaim S.455 Tax Using Form L2P
Form L2P is a separate, standalone form (available online or via post). It is not part of the CT600A supplementary pages. CT600A is used specifically for reclaims made within 2 years of the end of the accounting period in which the loan was taken out. Form L2P is specifically deployed for reclaims made after that 2-year window has closed, or when amending a return in writing.Form L2P can be submitted entirely on its own (either submitted through HMRC's online portal or posted separately). While it can be uploaded as a supplementary PDF attachment alongside your latest/current Company Tax Return (CT600) to speed up payment tracking, it is not structurally embedded into an amended return for the origin year.
This depends entirely on the 2-year statutory timeline. If you file the reclaim within 2 years of the 31 March 2026 year-end (i.e., before 31 March 2028), you do indeed amend the 31 March 2026 return using form CT600A (not Form L2P). However, if you are reclaiming after 31 March 2028 (2+ years later), you must use Form L2P, which is processed as a standalone claim or attached to the latest current return, not a retroactively amended 2026 return.
This is the point most directors miss. The refund does not appear automatically in the following year's return. It requires an active step by the company or its accountant.
HMRC's guidance confirms the mechanics:
The company can reclaim the s.455 tax nine months and one day after the end of the accounting period in which the loan was repaid or released. This relief is given by amendment to the CT600 return for the period in which the s.455 tax was originally charged.
That nine-months-and-one-day delay after the repayment period is the element that consistently frustrates directors who have repaid promptly.
The Nine-Month Waiting Period: Why It Exists and How It Works
A loan repaid during the accounting year ended 31 March 2027 triggers a reclaim entitlement that cannot be made until 1 January 2028. HMRC does not process the refund immediately on receiving the amended return before that date, even if the amendment is filed early.
The delay is deliberate. It mirrors the original nine-month payment window and prevents abuse of the mechanism. Without it, a director could repay on 1 April, reclaim immediately, and then re-draw the loan the following day.
In practice, this means the timeline from repayment to refund receipt typically runs to twelve months or more when you account for the filing window after the year in which repayment occurred, plus HMRC's processing time.
Here is how the sequence looks for a company with a 31 March year end:
Event | Date |
Loan outstanding at year end | 31 March 2026 |
S.455 tax due date | 1 January 2027 |
Loan repaid | 15 July 2027 |
Earliest date to file reclaim (9 months after 31 March 2027) | 1 January 2028 |
Estimated refund receipt (allowing for HMRC processing) | February/March 2028 |
From repayment to refund: approximately eight months at minimum. More typically, nine to twelve months.
What Counts as Repayment
The loan can be cleared in several ways, each of which triggers the reclaim entitlement:
Actual cash repayment is straightforward. The director transfers funds back into the company's bank account and the loan account is cleared.
Dividend vote is common and worth handling carefully. A dividend declared in an amount sufficient to clear the loan is treated as a repayment at the date the dividend is voted, provided the company has distributable reserves. The dividend should be documented with a proper board minute and dividend voucher.
Salary offset works where the company decides to pay the director a bonus and simultaneously apply it against the loan. The net effect is a cleared loan, but PAYE and NIC must be accounted for on the gross salary before the offset.
Write-off or waiver: if the company formally waives the loan, this counts as a release. It is treated as a distribution to the director and may give rise to income tax in the director's hands. This is not the cleanest route and generally applies in restructuring or winding-up scenarios rather than routine planning.
A benefit in kind arises on the loan while it is outstanding (if over £10,000 and below the official rate), and the s.455 charge applies to the amount outstanding at the accounting year end. Repayment by dividend, salary, or cash all qualify as clearing the loan for s.455 purposes, but each has its own tax treatment that needs to be handled correctly.
The Bed-and-Breakfasting Rule
HMRC introduced anti-avoidance rules in 2013 to prevent directors from repaying their loan shortly before the year end and then re-drawing it shortly afterwards.
Where a director repays a loan of £5,000 or more within thirty days before the end of the accounting period and then re-draws from the company within thirty days after the end of that period, HMRC treats the original loan as still outstanding for s.455 purposes. The repayment is ignored, and the s.455 charge applies as if the loan had not been cleared.
The rule also applies where the intention from the outset was to make a further advance, even if the thirty-day window is not technically breached. HMRC looks at the substance.
This catches a pattern that was quite common in owner-managed businesses in Greater Manchester and elsewhere, where directors would clear the DLA in March and re-draw in April, effectively running a permanent overdrawn loan account while technically clearing it each year. That approach no longer works.
If the company's loan balance is consistently high and the director genuinely cannot repay it within nine months, the better approach is usually to take a properly structured dividend (if reserves allow) or to consider whether the drawings represent salary that should be processed through payroll instead.
How to File the L2P Reclaim Correctly
The reclaim is submitted by amending the company's CT600 return for the year in which the s.455 charge was originally paid. In practice, this means going back into the corporation tax return for the earlier period and adding the L2P data through the CT600A supplementary pages.
Most commercial accountancy software (CCH, Iris, TaxCalc, and similar) includes the L2P fields within the CT600 suite. The amendment is submitted online through HMRC's Corporation Tax Online service or via approved software.
What the amendment must include:
The original s.455 charge paid, the amount being reclaimed, the date of repayment or release of the loan, confirmation that the nine-month waiting period from the end of the repayment accounting period has passed, and the company's payment reference details so HMRC can match the refund.
If the accountant who filed the original return is no longer acting, the amended return needs to be filed by whoever currently holds authority to act. Ensure the 64-8 authorisation (agent authorisation) is current before attempting to amend.
HMRC's processing time for s.455 reclaims submitted by amendment is typically four to eight weeks from receipt of the correct amendment, though it can run longer during periods of high demand. The refund is paid directly to the company's bank account if BACS details are registered, or by cheque otherwise. BACS is faster and significantly more reliable.
Common Errors That Delay the Refund
In practice, the delays almost always come from one of three sources.
The first is filing the amendment before the nine-month waiting period has elapsed. HMRC will reject or return the claim if it is received before the entitlement date. Some practitioners file immediately after the repayment period year end, not realising the clock runs for nine months from that date. File early and you may get it back, or it may simply sit unprocessed until HMRC's systems catch up.
The second is amending the wrong period. The amendment goes to the year in which the s.455 charge was paid, not the year of repayment. If a director repaid a loan in July 2027 and the charge arose in the year ended 31 March 2026, the amendment targets the March 2026 return. Filing the amendment against the March 2027 return achieves nothing.
The third is incomplete documentation. Where the repayment was made by dividend rather than cash, HMRC may request the board minute and dividend voucher. If the dividend was not properly documented at the time, the reclaim can stall. Board minutes for dividends should be dated and signed contemporaneously, not backdated later when the reclaim is filed.
There is also a less common error worth mentioning. Some directors believe the s.455 tax carries interest if HMRC delays the refund. HMRC does not pay repayment interest on s.455 tax refunds in the same way it does for overpaid corporation tax, because the s.455 charge is treated as a payment on account rather than a final tax settlement in the traditional sense. If interest recovery is important to you, the practical answer is to minimise the outstanding loan in the first place rather than relying on interest from a delayed refund.
When the Loan Is Written Off Rather Than Repaid
A written-off loan is treated as a release for s.455 purposes, which triggers the reclaim entitlement on the same timing basis as a cash repayment. The nine-month waiting period applies in the same way.
The important additional point is the tax treatment in the director's hands. When a company writes off a director's loan, the amount written off is treated as a distribution. The director receives an income tax charge at the dividend rates (8.75% basic, 33.75% higher, or 39.35% additional rate in 2026/27) on the written-off amount, after the dividend allowance.
This is not a PAYE charge but is reported through Self Assessment.
The company also loses the ability to recover the loan as a commercial debt. Write-offs tend to feature in situations where a company is winding down or where the director genuinely cannot repay and the relationship between the company and director is being formally resolved.
For a going concern with a temporary overdrawn director's loan, a write-off is rarely the right answer. A properly documented dividend (where reserves allow) achieves a cleaner result, clears the loan account with appropriate documentation, and avoids the framing of the written-off amount as a deemed distribution that HMRC might scrutinise more carefully.
What Happens If the Company Goes Into Liquidation Before the Loan Is Repaid
Where the company enters insolvent liquidation with a director's loan outstanding, the liquidator can pursue the director personally for the amount owed. The director is a creditor of the company in respect of the s.455 tax that was paid but the company is also a creditor of the director for the outstanding loan.
In liquidation, the s.455 reclaim can still be made by the liquidator, who files the L2P amendment on behalf of the company. The refund becomes an asset of the company in liquidation, available to creditors. The director cannot receive the refund directly in this scenario; it goes into the liquidation estate.
If a solvent liquidation (MVL) is planned and there is an outstanding director's loan, clearing the loan before the winding-up is started is considerably cleaner. The s.455 reclaim can then be made in the normal way, the refund received by the company, and the distribution to shareholders made as part of the capital distribution within the MVL.
A Practical Checklist for Director Loan Reclaims
Before filing the L2P reclaim, confirm the following:
The loan was repaid, released, or written off in the relevant accounting period. Identify the exact date.
Nine months and one day have elapsed since the end of the accounting period in which repayment occurred.
The amendment targets the correct return period (the year the s.455 charge was paid, not the year of repayment).
The repayment is properly documented. If by dividend, the board minute and voucher are dated correctly. If by salary, PAYE was run correctly. If by cash, the bank transfer is visible in the company accounts.
HMRC's BACS payment details for the company are registered and current.
The agent authorisation is in place if the accountant is filing on behalf of the company.
The amended return has been reviewed to ensure no other inadvertent changes have been made to the original filing.
Key Takeaways
S.455 tax is charged at 33.75% on director loans outstanding nine months after the company year end. It is reclaimable once the loan is cleared, but not immediately.
The reclaim is made by amending the CT600 return for the year the charge was paid, using the L2P supplementary pages.
The reclaim can only be made nine months and one day after the end of the accounting period in which the loan was repaid. This is the most commonly misunderstood timing rule.
Filing the amendment against the wrong accounting period, or before the waiting period expires, are the two most common errors. Both delay the refund significantly.
Where repayment is made by dividend, the documentation must be complete and contemporaneous. HMRC may ask for it.
Bed-and-breakfasting (repaying the loan and re-drawing within thirty days either side of the year end) no longer works. HMRC treats the original loan as still outstanding for s.455 purposes.
Interest is not payable by HMRC on s.455 refunds in the same way as standard overpaid tax. Minimising the loan balance before the year end is a more effective strategy than banking on interest recovery later.
FAQs
Q1: How does the timing for submitting Form L2P differ if the director’s loan was partially repaid over several accounting periods?
In my experience with clients who’ve drip-fed repayments into their company, this is where things get tricky and many miss out on full relief. You can only claim for the portion repaid in each specific accounting period, and the nine-month-and-one-day waiting rule applies separately to each slice. For instance, consider a Manchester-based retailer who repaid £20,000 in year one and £15,000 in year two of a larger overdrawn balance. They had to track each repayment’s accounting period carefully on the L2P to avoid HMRC querying the claim. The key is meticulous loan ledger records showing clear dates and amounts—get this wrong and you could face delays or partial rejection. Always double-check against your company’s year-ends before submitting.
Q2: What happens to the s.455 reclaim if the company has other outstanding Corporation Tax liabilities?
Well, it’s worth noting that HMRC often offsets the refund against any debts first. I’ve seen this with several high-earning director clients who had underpaid CT from previous years. The good news is you still get the net amount, but it won’t arrive as fresh cash if you owe elsewhere. In one case with a construction firm in Birmingham, the offset actually cleared a nagging small balance and left a tidy credit. Review your overall CT position before claiming to manage cash flow expectations.
Q3: Can self-employed individuals who incorporate their business later still reclaim s.455 tax on pre-incorporation loans?
This one comes up more often than you’d think with freelancers turning limited. Generally, s.455 applies only to loans from the close company post-incorporation. However, if you transferred assets or cleared personal overdrafts via the new company, you need to scrutinise the transaction carefully. I advised a Leeds graphic designer who had an informal loan cleared post-incorporation; we successfully reclaimed by treating it properly as a participator loan with solid evidence. The pitfall is assuming old sole-trader debts qualify— they usually don’t, so document everything as a fresh company advance.
Q4: How do Scottish or Welsh company directors need to approach Form L2P differently from those in England?
In practice, there’s little difference in the L2P process itself, as s.455 is a corporation tax matter handled UK-wide by HMRC. That said, if your company has trading links across borders or you’re a Scottish taxpayer personally, it can affect overall planning. I’ve had clients in Edinburgh whose personal dividend tax rates influenced whether to repay via salary, dividend, or loan clearance. The reclaim timing remains the same, but always factor in any devolved tax nuances when deciding repayment strategy to optimise your total tax position.
Q5: What evidence should accompany an L2P claim when the loan was cleared by dividend rather than cash repayment?
It’s a common mix-up, but clearing via dividend is perfectly acceptable if properly documented. HMRC will want to see board minutes declaring the dividend, entries in the loan account, and confirmation it wasn’t just a book entry without real economic effect. In my experience with a London tech startup client, providing the dividend voucher and bank transfer (even if net of tax) smoothed the process. Without clear audit trails, claims can drag on—keep it clean and contemporaneous.
Q6: Is there a deadline for making the L2P claim after the nine-month waiting period?
Yes—generally within four years from the end of the accounting period in which the repayment occurred. I’ve seen clients push this and lose out, which is heartbreaking when it’s reclaimable money. One shop owner in Bristol nearly missed the window on an older loan; we filed just in time. Don’t treat the nine-month mark as the only clock—mark the four-year limit in your diary and submit promptly once eligible.
Q7: What if multiple participators (like family shareholders) have loans—does this complicate the Form L2P?
Absolutely, and it’s a frequent edge case. You’ll need to break down each participator’s loan repayments separately on the claim, with supporting schedules. I recall a family-run catering business in Cardiff where three siblings had overdrawn accounts; itemising each one prevented queries. The company reclaims the tax, but poor allocation can lead to disputes. Prepare a clear summary table for HMRC to make their review straightforward.
Q8: Can you use Form L2P if the company is now dormant or in the process of striking off?
In my experience, yes, provided the company still exists when you submit. HMRC has shown flexibility here, but you’ll likely need extra evidence like final accounts or liquidation details. One client wound up their dormant property company after repaying director loans—we successfully reclaimed by attaching full loan history. Act before striking off, as a non-existent company can’t easily claim.
Q9: How quickly does HMRC typically process and pay an L2P refund?
Processing usually takes 8-12 weeks or longer during busy periods, though the actual payment timing ties back to the nine-month rule. Don’t bank on it arriving instantly. I’ve had clients chase after 10 weeks only to find a simple missing bank detail held things up. Submit complete information and follow up politely via your agent portal if needed.
Q10: Does writing off the loan instead of repaying it allow an L2P reclaim, and what are the personal tax consequences?
Yes, a formal write-off qualifies for company relief under s.458, but the participator usually faces a dividend tax charge on the amount written off. This is a common pitfall for struggling businesses. I advised a high-earner in Newcastle who wrote off part of a loan; the company reclaimed s.455 successfully, but he had to report it personally. Weigh the company cash benefit against the individual’s tax hit carefully.
Q11: What should high-earners watch out for when timing loan repayments around personal tax bands?
High earners often benefit from aligning repayments to avoid pushing themselves into higher dividend tax bands in the same year. In practice, spreading repayments or using salary can help. One client near the £100k+ threshold in Surrey timed a large repayment post his bonus to manage his marginal rate. L2P timing is company-focused, but personal planning around it delivers real savings.
