Cash flow gets tight in most small companies at some point. If you’re a director, one quick way to steady the ship is to inject funds yourself as a loan.
An interest-free loan from a director to the company can be simple, fast and flexible - but there are important legal, tax and accounting points you need to get right from day one.
In this guide, we’ll walk through how these loans work under UK law, what to document, the pros and cons of taking security, and the common pitfalls to avoid as your business grows.
What Is An Interest-Free Director’s Loan To A Company?
An interest-free director’s loan is money a company director lends to the company with no interest charged. It’s commonly used to bridge working capital gaps, fund a project or cover an unexpected expense without the cost or delays of external finance.
This is different to:
- Equity funding - putting in cash for new shares.
- Loans from the company to the director - which are tightly regulated and can trigger tax issues (that’s the opposite direction).
- Commercial loans - from banks or third parties, usually interest-bearing and with formal underwriting.
At law, the company is a separate legal person from you as a director. So this is a contract between two separate parties: you (the lender) and the company (the borrower). That means it should be treated like any other external finance and recorded properly.
Is It Legal In The UK? Key Company Law Rules
Yes - a director can legally lend money to their company, including on an interest-free basis. There is no prohibition on a director advancing funds to the company.
However, a few company law rules apply so you stay compliant and avoid conflicts later.
1) Directors’ Duties And Conflicts
Under the Companies Act 2006, directors must promote the success of the company, exercise independent judgment, and avoid conflicts of interest. A loan from a director is a “related party” transaction, so you should:
- Disclose your interest to the board before the company enters the loan (declare it formally and minute it).
- Have a proper board resolution approving the loan and its terms.
- Ensure terms are fair and in the company’s interests, particularly if security is involved.
If there are other directors, the conflicted director should abstain from voting where your articles require it. Good governance now prevents disputes later.
2) Shareholder Considerations
For most private companies, shareholder approval isn’t legally required just to accept a loan from a director. But if the company is granting a charge over key assets, or if there are multiple shareholders with different risk appetites, it’s wise to document how such loans are handled going forward (priority, repayment triggers, security, conversion rights, etc.). These rules often live in a Shareholders Agreement so everyone knows where they stand.
3) Recording Security
If the company grants fixed or floating security to the director (e.g. a debenture), it must be registered at Companies House (MR01) within the statutory time limit or the security could be void against a liquidator and other creditors. If you plan to take security, consider using a General Security Agreement tailored to your business and assets.
4) Insolvency And Priority
If the company later struggles financially, repayments to a director may be scrutinised. Paying a connected person (like a director) ahead of other creditors can be challenged as a “preference” under the Insolvency Act if the company was insolvent at the time or became insolvent because of the payment. If in doubt, get advice before repaying director loans when cash is tight.
Tax And Accounting Treatment Of Interest-Free Director Loans
The tax and accounting position depends on structure and size, but here are the key points to know - and why speaking with your accountant before finalising terms is a smart move.
Corporation Tax
- There’s no corporation tax just because the company receives an interest-free loan. Loan proceeds aren’t taxable income.
- Because no interest is paid, there’s no interest expense to deduct. That means you miss out on a potential tax deduction, but you also avoid the cash cost of interest - a trade-off many early-stage companies prefer.
- If the loan is later waived or written off by the director, a taxable credit may arise for the company under the “loan relationships” rules. The exact outcome can be complex and fact-specific (for example, whether the lender is a connected person and how accounting standards measure the release). Get tailored tax advice before agreeing a write-off or debt forgiveness.
Director’s Personal Tax
- Lending money to your company on an interest-free basis generally doesn’t create a personal tax charge for you just because it’s interest-free.
- If you later charge interest, that interest is your personal taxable income.
- Separate rules apply where the company lends to a director - that’s not this scenario, but if you have both directions in play, consider a single, clear policy and read up on shareholder and director loans to avoid unexpected charges.
Accounting And Disclosures
- Related party disclosures: UK GAAP requires related party transactions to be disclosed in the financial statements (e.g. the loan balance, terms, and any security). Transparency is key.
- Measurement: Under FRS 102, some interest-free loans are measured at present value (with an imputed interest effect) unless they’re repayable on demand. Micro-entities under FRS 105 may measure at transaction price. Your accountant will apply the right standard for your company size and loan terms.
- Balance sheet classification: Short-term if due within 12 months; otherwise long-term. If repayable on demand, it’s normally current.
How To Document An Interest-Free Loan Properly (Step-By-Step)
Keep it simple, clear and compliant. Here’s a practical process you can follow.
Step 1: Agree The Commercial Terms
Before you draft anything, decide on the key points:
- Amount and drawdown (one lump sum or multiple tranches).
- Repayment date (on demand, fixed date, or flexible schedule).
- Interest rate (0% - confirm this explicitly).
- Security (secured vs unsecured, and what assets are covered).
- Subordination (will your loan rank behind bank finance?).
- Default triggers (e.g. non-payment, insolvency, breach of covenants).
- Early repayment rights (can the company repay at any time?).
- Conversion rights (if you might convert debt to equity later, that’s a different structure - see the discussion on debt-for-equity below).
Step 2: Put A Written Loan Agreement In Place
Even if you’re the sole director and shareholder, a clear, signed loan document avoids confusion, helps your accountant, and makes future events (new investors, sale, audit) much smoother. It should cover the items above and standard protections for both sides.
Resist the urge to DIY - a short, tailored agreement is far better than a generic template that doesn’t fit your facts. If you do want a sense-check of what goes in, our overview of Loan Agreement templates explains the usual clauses in plain English.
Step 3: Pass A Board Resolution
Document the decision to accept the loan and enter the agreement. The resolution should note the amount, key terms, any conflicts disclosed by the lending director, and authority to sign. Keeping clean records is part of good governance and will help during due diligence or audits.
If you need a formal document to accompany your minutes, our Directors’ Resolution template service can be used as part of a tidy record-keeping process.
Step 4: Execute The Documents Properly
Make sure the company signs the loan agreement in line with your articles and the Companies Act signing rules. If using a deed (common for security or where no consideration passes), ensure the formalities are met.
Step 5: Register Any Security
If the loan is secured, file the charge at Companies House within the statutory time window and retain the MR01 acknowledgement. Missing the deadline can void the security against third parties.
Step 6: Keep A Clear Loan Ledger
Track all advances and repayments against the loan balance. Avoid blurring a director’s loan account with payroll or expense reimbursements - mixing transactions is a frequent source of headaches.
Should You Take Security Or Keep It Unsecured?
Security is optional. Many directors leave loans unsecured to keep things simple and avoid administrative steps. Others prefer taking security to sit alongside bank lenders or to protect a larger injection.
Pros Of Taking Security
- Priority on insolvency: A properly registered fixed or floating charge can put you ahead of unsecured creditors.
- Negotiation leverage: Security can help you agree repayment plans with other creditors if times get tough.
- Clarity with future investors or lenders: Everyone can see the capital stack and priorities.
Cons And Risks
- Administration: Drafting a debenture or General Security Agreement and registering charges adds steps and cost.
- Bank covenants: A senior lender may prohibit junior security or require a deed of priority or subordination.
- Insolvency scrutiny: Security granted shortly before insolvency can be challenged in some circumstances.
In practice, the right answer depends on how much you’re lending, existing finance, and the company’s risk profile. If you expect to raise external capital soon, an unsecured loan with a clear repayment or conversion plan can be cleaner.
Common Pitfalls And How To Avoid Them
We regularly see the same problems crop up with director loans - here’s how to stay clear of them.
No Written Terms
Handshake terms are easy to forget or misremember, especially if multiple advances are made over time. Always sign a short, clear loan agreement and minute the approval.
Blurring Loans With Expenses Or Wages
Don’t mix director expense reimbursements or salaries with loan balances. Keep separate ledgers and make sure your director remuneration strategy is documented and tax-efficient in its own right.
Granting Security But Missing Registration
Unregistered charges can be ineffective against administrators or liquidators. If you take security, register it on time, keep the paperwork, and align it with any bank covenants.
Repaying A Director Ahead Of Other Creditors When Insolvent
When cash is tight, think carefully before repaying a connected creditor (like a director). It can be challenged as a preference. If the company is insolvent or close, take advice and prioritise creditor interests as required by your duties.
Not Thinking Ahead To Future Funding
Imagine you raise investment in six months. Will new investors expect your loan to be repaid, subordinated, or converted? Planning now saves a rushed renegotiation later. If conversion is on the cards, consider a structured path like a debt-for-equity swap drafted to protect existing shareholders and meet regulatory requirements.
Overlooking The Big Picture
A loan is only one tool in your founder finance toolkit. Sometimes equity, a small interest-bearing facility, or staged advances tied to milestones better supports cash flow with fewer downstream issues. Speak to your accountant about modelling the options before you lock in terms.
Alternatives And Variations You Should Consider
Interest-free isn’t the only way to support your company. Depending on cash flow, tax and growth plans, consider these variations.
Interest-Bearing Director Loans
Charging a modest, arm’s-length interest rate creates a deductible expense for the company and a predictable return for you. You’ll need to declare the interest as personal income. Keep rates and terms defensible and document them in a proper Loan Agreement.
Convertible Loans
Debt that can convert into shares at a later date can align repayment with growth. These instruments carry additional legal and tax considerations (valuation, pre-emption rights, dilution, investor protections). If you’re thinking along these lines, treat it as a capital raise and ensure your Shareholders Agreement and articles support the mechanics.
Equity Injection
Sometimes the cleanest option is buying more shares. There’s no repayment pressure, and your balance sheet strengthens. Be mindful of share pricing, pre-emption rights and documentation standards - especially if others hold shares. If you’re mapping out a bigger raise later, a clear term sheet and capital plan can help the business stay investor-ready.
Structured Packages With External Lenders
Bank or alternative finance alongside a subordinated director loan can work well, but ensure subordination is expressly documented and consistent with any facility agreement. Your board minutes should record the rationale so it’s clear you were acting in the company’s interests.
FAQs: Quick Answers To Common Questions
Does An Interest-Free Director Loan Need To Be In Writing?
Legally, an oral loan can exist - but it’s risky. Put a written agreement in place and minute the board decision. This is essential housekeeping for future diligence, audits or investor conversations.
Can I Repay Myself At Any Time?
Only if the agreement allows it and the company is solvent. When the company is under financial stress, directors must prioritise creditor interests - repaying a connected party may be challenged in insolvency.
Should I Register A Charge?
Only if you’re taking security. If unsecured, there’s nothing to register. If secured, registration is critical to protect priority.
Will HMRC Charge Tax Because It’s Interest-Free?
No tax arises simply because the loan is interest-free. However, if the loan is later released or converted, tax and accounting effects can arise - get advice before making changes.
What If I’m The Only Director And Shareholder?
You still should document the loan and pass a board resolution. Keeping clean records protects you if the company grows, brings in investors, or faces scrutiny.
Key Documents To Have In Place
- Loan Agreement (or Deed of Loan) - sets out the amount, term, interest (0%), repayment and default.
- Board Resolution - records conflict disclosure and approval to enter the loan.
- Security Documents (optional) - e.g. a General Security Agreement plus Companies House registration if secured.
- Shareholder Document - rules of the game for future director loans, priorities and conversions often live in a Shareholders Agreement.

Key Takeaways
- An interest-free loan from a director to a company is lawful and often a fast, flexible way to support cash flow - but treat it like external finance and document it properly.
- Record conflict disclosures and pass a clear board resolution approving the loan before signing.
- Use a written Loan Agreement that clearly states the amount, 0% interest, repayment terms, and any security or subordination; register any charge on time if you take security.
- Understand the tax and accounting impacts: there’s no tax on receiving the loan; there’s no interest deduction; releases or conversions can have consequences - speak to your accountant first.
- Avoid common pitfalls like missing paperwork, mixing loans with expenses or wages, repaying a director when insolvent, or granting security without registration or lender consent.
- Plan ahead for future funding: if you may convert, align your capital plan and Shareholders Agreement; if you need priority, consider a properly drafted General Security Agreement.
