Lending money to your child so they can start or grow a business sounds straightforward until it goes wrong. And when it goes wrong inside a family, the fallout is both financial and personal. The parent who “just wanted to help” finds themselves an unsecured creditor in an insolvency, or discovers HMRC treats the arrangement as a gift, or watches a divorce settlement carve up the loan as though it never existed. These outcomes are entirely preventable \u2014 but only if you treat the transaction with the same rigour a commercial lender would from day one.<\/p>\n
Most family business loans begin with a conversation over dinner and a bank transfer the following morning. No written agreement, no interest rate, no repayment schedule. The implicit assumption is that trust replaces paperwork. It does not. Without formal documentation, you face three immediate problems. First, HMRC may treat the advance as a gift rather than a loan, with potential inheritance tax consequences if you die within seven years. Second, if your child’s business fails and enters administration, an insolvency practitioner will scrutinise any undocumented family loan and may challenge it as a preference or transaction at undervalue. Third, if your child separates from a spouse or partner, the family court may disregard an undocumented loan entirely when dividing matrimonial assets.<\/p>\n
Every one of these risks is eliminated or dramatically reduced by a properly drafted loan agreement executed as a deed.<\/p>\n
HMRC does not care what you intended<\/em>. It cares what you can prove<\/em>. If there is no written agreement, no interest, no repayments, and no enforcement mechanism, the “loan” looks indistinguishable from a gift \u2014 and HMRC will treat it as one. The consequences are significant:<\/p>\n The pragmatic middle ground is to charge a modest but genuine interest rate \u2014 even 1% or 2% above the Bank of England base rate \u2014 and actually collect it. This creates an unmistakable audit trail that the arrangement is a commercial loan, not parental generosity dressed up as debt.<\/p>\n If your child is trading through a limited company, the borrower should almost always be the company, not your child personally. Lending to your child personally when the money is destined for the company creates several problems: the company may not be able to deduct the interest as a business expense, the loan sits outside the corporate structure in an insolvency, and tracing the funds becomes unnecessarily complicated.<\/p>\n However \u2014 and this is where many parents get caught \u2014 if the company is the borrower and it fails, you are an unsecured creditor ranked behind HMRC, employees, and any secured lenders. Your recovery may be pennies in the pound, or nothing. If this risk is unacceptable, you need to take a personal guarantee<\/strong> from your child alongside the company loan agreement, or take security over specific assets. Be honest with yourself about whether you can stomach losing the money entirely. If you cannot, structure accordingly.<\/p>\n A robust family business loan agreement should be executed as a deed<\/strong>, not a simple contract. The practical reason is limitation periods: obligations under a deed are enforceable for 12 years, compared with just 6 years for a standard contract. Given that family business loans often have long or informal repayment horizons, this extended period provides crucial protection.<\/p>\n The agreement should cover, at minimum:<\/p>\n Taking a charge over business assets \u2014 equipment, stock, intellectual property \u2014 is sensible for larger loans. Register the charge at Companies House within 21 days of creation; an unregistered charge is void against a liquidator. For significant sums, some parents take a second charge over their child’s residential property. This is legally possible but emotionally fraught: if your child defaults, are you genuinely prepared to enforce a charge that could result in the sale of their home? If the answer is no, do not take the charge. A security interest you will never enforce is worse than no security at all, because it creates a false sense of protection.<\/p>\n For you as lender:<\/strong> Any interest you receive is savings income and must be declared on your self-assessment tax return. If you are a higher-rate taxpayer, you will pay 40% on the interest received. Factor this into the rate you charge.<\/p>\n For the borrowing company:<\/strong> Interest paid on the loan is generally deductible as a business expense, provided the loan is used wholly and exclusively for the purposes of the trade. If HMRC considers the interest rate uncommercial \u2014 either too high (suggesting disguised profit extraction) or at zero (suggesting a gift) \u2014 they may disallow the deduction or reclassify the payment.<\/p>\n Inheritance tax planning:<\/strong> A genuine, documented loan is a debt owed to your estate. On your death, the outstanding balance is an asset of your estate and will be subject to IHT. However, this is still preferable to an outright gift made less than seven years before death, where you lose both the capital and the tax efficiency. You can, of course, forgive portions of the loan annually within your \u00a33,000 annual gift exemption, gradually reducing the estate’s exposure.<\/p>\n You need to confront this possibility before you lend, not after. If the company enters creditors’ voluntary liquidation, the liquidator will examine all transactions with connected parties in the two years preceding insolvency. A loan made at arm’s length on commercial terms, properly documented and consistently serviced, will withstand scrutiny. A poorly documented arrangement with no repayments and no interest will be challenged \u2014 and may be set aside entirely under the Insolvency Act 1986.<\/p>\n If your child traded as a sole trader or in partnership rather than through a limited company, the stakes are higher: they are personally liable for all business debts, and your loan competes with every other creditor against their personal assets.<\/p>\n Sit down with your child and a solicitor \u2014 the same solicitor should not act for both of you, to avoid conflicts of interest \u2014 and agree the terms in writing before a single pound changes hands. Discuss what happens if the business fails, what happens if your child wants to bring in a new business partner, and what happens if you need the money back unexpectedly for your own care needs. These conversations are uncomfortable. They are infinitely less uncomfortable than the alternatives: a destroyed relationship, an HMRC investigation, or watching your retirement savings vanish into an insolvent company with no prospect of recovery. Structure it properly, document it thoroughly, and treat it as what it is \u2014 a serious financial commitment that deserves professional rigour.<\/p>\n Disclaimer:<\/strong> The information provided in this article is for informational purposes only and should not be considered financial or legal advice.
