Lending money inside a family is easy; remembering the details three years later is not. A family loan tracker is simply a written record of what was lent, what has been repaid and what is still outstanding — and in 2026, with frozen tax thresholds and tighter lender scrutiny of deposit money, it has quietly become one of the most useful documents a British family can keep. Without one, a loan drifts into being “a gift, probably”, and that ambiguity is where families, lenders and HMRC all end up in disagreement.
This guide explains what to record, how tracking interacts with mortgage applications and inheritance tax, and how to build a template that would actually stand up if challenged.
Key Takeaways
- A loan record should pair a written agreement with a running ledger of every payment, so the outstanding balance can be proved on any given date.
- Under the Limitation Act 1980, obligations in a simple contract are enforceable for six years; obligations in a deed carry a twelve-year limitation period.
- Money intended for a mortgage deposit must be disclosed to the lender for what it truly is — signing a gifted deposit letter for money that is really a loan is mortgage fraud.
- HMRC’s annual gift exemption is £3,000 per tax year, with one unused prior year available to carry forward, giving up to £6,000; the inheritance tax nil-rate band stands at £325,000 and is frozen.
- An unrepaid loan remains an asset of the lender’s estate on death, so accurate tracking protects executors and beneficiaries alike.
What is a family loan tracker and why does it matter?
It is a written ledger recording the principal advanced, dates, agreed interest (if any), every repayment received and the running balance. It sits alongside a signed loan agreement rather than replacing it. Its purpose is evidential: to prove, years later, that money was lent rather than given, and exactly how much remains owed.
Our experience across the agreements families create is consistent: the dispute is almost never about whether money changed hands. Bank statements settle that. The dispute is about what it was and what has been paid back. Memory is a poor witness, and siblings who were not in the room have no reason to accept one version over another.
Three situations where a contemporaneous record decides the outcome:
- Relationship breakdown. Money advanced to a child and their partner is frequently claimed as a gift to the couple. A dated ledger showing repayments rebuts that.
- Death of the lender. Executors must value the estate. An outstanding debt owed to the deceased is an asset they are legally obliged to collect.
- Sibling fairness. Unequal lifetime support causes more probate friction than almost anything else. Written records convert a grievance into arithmetic.
What should a family loan tracker actually record?
At minimum: the parties, the principal, the advance date, the interest rate or an express statement that the loan is interest-free, the repayment schedule, every payment with its date and amount, and the resulting balance. Anything that changes the deal — a payment holiday, a reduction, a partial waiver — must be recorded in writing too.
| Field | Why it matters |
|---|---|
| Date and amount of each advance | Starts the limitation clock and evidences the sum lent |
| Interest rate, or “interest-free” | Silence invites argument; interest received is taxable savings income for the lender |
| Repayment schedule and method | Standing orders with consistent references are self-documenting |
| Running balance after each payment | The single figure an executor, lender or court needs |
| Variations and payment holidays | Verbal forbearance is often later recast as a waiver of the debt |
| Security, if any | Determines whether the lender ranks ahead of other creditors |
One technical point most articles miss: a written acknowledgement of the debt, or a part payment, generally restarts the limitation period under the Limitation Act 1980. A tracker that the borrower confirms annually is therefore not just a record — it actively preserves enforceability. If you want maximum protection, execute the underlying family loan agreement as a deed and gain the twelve-year period rather than six.
How does a family loan affect a mortgage deposit application?
Decisively. UK lenders assess the source of deposit funds as well as affordability. Most residential lenders will not accept a borrowed deposit at all; those that do must be told, and will treat the repayments as a committed outgoing. A loan presented to the lender as a gift is not a grey area — it is fraud.
The standard document is a gifted deposit letter, in which the giver confirms the money is an outright gift, that it is non-refundable, and that they retain no interest in the property. That letter becomes false if any of the following is true:
- Repayment is expected, whether on a schedule or “when you can”.
- The giver expects a share of the sale proceeds or any beneficial interest.
- A side agreement, declaration of trust or informal understanding contradicts the letter.
Signing a declaration you know to be untrue to obtain a mortgage is an offence under the Fraud Act 2006. Realistic consequences include the offer being withdrawn, the mortgage being called in, a CIFAS marker that follows the borrower for six years, and prosecution. Solicitors are obliged to report what they find during source-of-funds checks; the Financial Conduct Authority expects lenders to verify deposit provenance as part of their anti-money-laundering obligations.
The honest routes:
- Genuine gift. The money is given, the letter is true, and the lender is satisfied. Keep the gift recorded for inheritance tax purposes.
- Declared loan. Disclose it, accept reduced borrowing capacity, and document it properly.
- Equity share. The parent takes a recorded beneficial interest via a declaration of trust, with the lender’s knowledge. Note that if the parent already owns property anywhere in the world, the 3% SDLT higher rate can apply to the entire purchase price — check the position on GOV.UK Stamp Duty Land Tax.
How do HMRC rules apply to tracked family loans?
A loan is not a gift, so advancing it has no immediate inheritance tax effect. The unrepaid balance stays in the lender’s estate. Any interest charged is taxable savings income the lender must declare. If a loan is later written off, that forgiveness is treated as a gift at that moment, with the seven-year clock starting then.
Key figures, per HMRC:
- Annual gift exemption: £3,000 per tax year, with one unused prior year carried forward — up to £6,000.
- Small gifts: £250 per recipient per tax year, to any number of people, provided no other exemption covers that person.
- Nil-rate band: £325,000, frozen, with an additional residence nil-rate band where a home passes to direct descendants.
- Seven-year rule: gifts fall out of the estate after seven years. Taper relief between three and seven years reduces the tax due, not the value of the gift — a distinction that catches out a great many families.
A tracker is what lets your executor tell the difference between a debt to be collected and a gift to be declared. MoneyHelper offers free guidance on estate planning if your position is complex.
How do you set up a tracker and keep it current?
Start with a signed agreement, then maintain a simple spreadsheet or app alongside it. Use a dedicated bank reference for every payment, update the balance on the day money moves, and have both parties confirm the balance once a year in writing. Store everything where your executor can find it.
- Put the loan in writing before any money moves — ideally as a deed.
- Pay by bank transfer with a consistent reference such as “LOAN REPAY J SMITH”.
- Log every payment on the day: date, amount, allocation to interest or principal, new balance.
- Record variations in a short dated note signed by both parties.
- Send an annual statement and ask the borrower to confirm it by email.
- Keep a copy with your will, and tell your executor it exists.
Is a spreadsheet enough, or do I need a formal agreement?
A spreadsheet proves payments but not terms. On its own it cannot establish interest, repayment dates or what happens on default. Courts look for evidence of the parties’ intention to create legal relations, so pair your ledger with a signed agreement. A dedicated family loan app does both in one place.
What happens if a family loan was only ever verbal?
A verbal loan can be legally valid but is far harder to prove. You will need bank records, messages and a pattern of repayments to establish terms. Our guidance on proving a verbal family loan in court sets out the evidential hurdles. Documenting it now, retrospectively but honestly, is always better than leaving it.
Does charging interest to a family member cause tax problems?
Interest you receive is taxable savings income and must be declared to HMRC, typically through Self Assessment. Allowances change, so check the current personal savings allowance on GOV.UK rather than assuming. Interest-free loans create no income tax charge but may raise questions about whether the arrangement was really a gift.
What should my executor do with an outstanding family loan?
Executors have a duty to collect debts owed to the estate and include the outstanding balance in the inheritance tax account. If the will forgives the loan, that must be stated explicitly. Where a borrower is also a beneficiary, the debt is usually set against their share rather than demanded in cash.
Where should you start?
Good record-keeping is cheap insurance. It protects the lender’s estate, protects the borrower from being asked to repay money twice, and keeps everyone on the right side of lender declarations and HMRC. The families who run into trouble are almost never the ones who wrote things down.
If you are lending to relatives — or already have and never formalised it — you can create a written family loan agreement and track every repayment in one place with Chipkie, so the balance is never in doubt.
