A shareholder can fund a company through a loan as well as through shares. The two arrangements have different rights and expectations. A payment described informally as putting money into the business should be documented so everyone understands whether it is debt, equity or another contribution.
Identify the lender and purpose
Record the legal parties, amount and intended use of the funds. Distinguish a personal shareholder loan from money advanced by another company in the group. Confirm the bank trail and the date the company receives the funds.
A loan does not automatically increase the lender's shareholding or voting rights. If conversion into shares is intended, the conversion mechanism and future approvals need separate drafting and tax review.
Agree repayment and interest
Specify whether repayment is on demand, at a fixed date or in instalments. Consider early repayment, default and what happens if the shareholder sells their shares. Explain whether interest accrues, when it is paid and whether unpaid interest compounds.
Where a director lends money to the company and charges interest, HMRC guidance identifies reporting and tax deduction obligations. The treatment should be checked for the actual lender, residence and arrangement; do not copy an individual director example uncritically into every corporate or overseas loan. [1]
Consider security and priority
An unsecured shareholder loan may rank differently from a lender's secured debt in an insolvency. If security is proposed, obtain advice on the instrument, consents and registration. Companies House guidance provides a twenty-one-day registration period for relevant charges, starting the day after creation. Missing it can have serious consequences. [2]
Existing finance documents may restrict additional debt, security or repayment to shareholders. A new investor may also require the loan to be subordinated, converted or repaid as part of the investment terms.
Loan documentation checklist
- Parties, principal and funding date.
- Purpose and any drawdown conditions.
- Interest, repayment and default terms.
- Security and required third-party consents.
- Priority or subordination arrangements.
- Approvals, tax treatment and accounting records.
Test the difficult scenarios
Consider a cash shortage, disagreement between owners and a sale of the business. Can one shareholder demand repayment that the company cannot afford while another expects funds to remain invested? The agreement should address that tension before money is advanced.
Make the debt distinguishable from an equity contribution
Record the parties, amount advanced and intended legal character when funding is provided. If the company receives money before documents are finalised, resolve the terms promptly and preserve the actual chronology. Do not present a later agreement as though it was signed at the earlier payment date. The records should explain what was agreed and when.
A shareholder loan may offer a repayment right that shares do not, but the agreement and company's circumstances determine its practical value. Clarify whether repayment is on demand, on fixed dates or subject to conditions. Avoid describing the funding as both permanent capital and immediately repayable cash depending on which outcome is convenient.
Test repayment against the company's other commitments
Prepare a cash-flow illustration showing the proposed repayments alongside operating costs and external debt. Check lending covenants and any subordination arrangement. A shareholder's expectation of priority does not make it effective against other creditors. Where security is proposed, obtain advice on the document, registration requirements and timing.
For example, two owners lend different amounts to fund expansion. Equal share ownership does not explain whether loan repayments should be equal or proportional to outstanding balances. State the agreed approach and assess whether external finance restricts it. This avoids turning a routine cash decision into a dispute about fairness and control.
Address interest and changes explicitly
State whether interest is payable, how it is calculated and when it is due. Ask the tax adviser about the reporting and payment treatment applicable to the actual lender and arrangement. Do not copy an interest clause from another company's loan without checking the parties and circumstances.
If further advances are expected, define how they are authorised and recorded. A flexible facility may be more suitable than repeatedly creating informal loans, but it still needs clear limits and terms. Keep amendments and drawdown records together so the outstanding obligation can be reconstructed without relying on the lender's memory.
Include the loan in exit planning
A sale of shares does not necessarily transfer or repay the shareholder's loan. Decide whether it will be settled, assigned or remain outstanding, subject to the documents and required consents. The purchase price should distinguish payment for shares from repayment of debt. Review guarantees and security releases as separate completion items.
Use Shareholder deadlock: options to discuss where unequal funding contributes to deadlock. Shareholders agreement review can help review how the shareholder agreement addresses funding and exits; the loan, security and tax documentation may require additional specialist work.
For example, equal shareholders may contribute unequal loans without changing equal ownership. A clear schedule of debt and equity prevents the unequal funding from being mistaken for an undocumented change in share rights or a promise of immediate repayment.
Frequently asked questions
Is money paid by a shareholder automatically equity?
No. Establish whether the payment is a loan, share subscription or another arrangement. Document the actual terms and reflect them consistently in the company records.
Can a shareholder demand repayment whenever they wish?
The loan terms and applicable circumstances matter. Check demand rights, maturity, subordination and other restrictions rather than assuming ownership creates an unrestricted withdrawal right.
Does security guarantee recovery?
No. Its effect depends on valid creation, registration where required, priority and asset value. Obtain advice on the proposed security and competing obligations.
Is the loan included automatically in a share sale?
Not necessarily. Address it expressly in the transaction: repayment, assignment or continuation may be intended, with separate documents and consents as required.
