Tax records for company loans

Company loans need a clear record of who lends, who borrows and the terms. Separate principal, interest and other charges, and distinguish a bank facility from a director or connected company arrangement. The tax analysis depends on the actual relationship and transactions, not simply the ledger account name.

Keep agreements, payment dates, calculations and approvals. Loans involving directors can create specific tax and reporting issues, while interest payments may have separate withholding or reporting requirements. Review proposed write-offs, releases or changes with the accountant before posting them as ordinary expenses.

Identify the lending relationship and its terms

Record the lender, borrower, legal entities, purpose and dates. Collect the agreement, amendments, security and guarantee documents. Separate principal, interest, arrangement fees and other charges. A monthly bank payment may include several components with different accounting and tax treatment. Do not post the entire amount as finance cost simply because the recipient is a lender.

HMRC's loan relationship guidance explains the corporate tax framework for relevant credits and debits. ^[1] The analysis can depend on the relationship, accounting treatment and specific tax rules. Provide the full facts rather than relying on the ledger name loan interest as proof that the amount is deductible or taxable in the expected period.

Keep movements and calculations reconcilable

Maintain a schedule from opening principal through advances, repayments and closing balance. Calculate interest using the actual terms and preserve rate changes. Reconcile lender statements and bank evidence, explaining differences such as accrued interest or fees. A closing balance confirmation is useful but does not replace the transaction history needed to assess timing or a later release.

For foreign currency loans, retain original currency amounts and exchange evidence. Identify hedging or related arrangements for specialist review where relevant. Do not allow unexplained differences to accumulate in a general exchange account without checking whether they relate to principal, interest or another transaction. Keep the accounting and tax schedules linked but distinct where adjustments apply.

Review directors and connected companies separately

Loans involving directors, shareholders or connected companies can create additional rules and reporting questions. HMRC's director loan guidance is relevant to those arrangements. ^[2] Identify the person's capacities and relationship rather than assuming every director account is the same as a commercial bank facility. Use Recording a director loan account for dated director movements and supporting evidence.

Ask about interest withholding, reporting, transfer pricing or other restrictions where the facts make them relevant. Do not assume all cross-border or connected payments receive ordinary treatment without assessment. Keep the lender's identity and residence information appropriate to the review, and distinguish actual contractual terms from an informal expectation that related parties will settle whenever cash permits.

Assess changes before posting them as routine adjustments

A waiver, write-off, restructuring or debt-for-equity arrangement can have consequences beyond removing a ledger balance. Obtain advice before signing or implementing the change. Preserve the original obligation, proposed terms and commercial reason. A company should not treat an accounting impairment as proof that the legal debt has been released, or a legal release as automatically producing the same tax result for both parties.

Use Selling a business with outstanding loans where loans affect a business sale and Interest income in a limited company for interest income. Check required approvals and the effect on security or guarantees. Keep the actual documents with the final accounting entries so a later reviewer can establish what changed and when. Avoid backdated agreements intended to make an earlier unexplained transfer appear to have had different terms.

For Corporation Tax record review, provide the loan schedule, contracts, statements and proposed changes. Ask for an integrated review of principal, interest, timing and any special relationship issues. Identify which work requires specialist tax or legal input beyond routine bookkeeping. Maintain the evidence annually and on each significant transaction so the company can explain its borrowing or lending position without reconstructing years of bank movements after a tax query arises.

Record a loan variation as a separate event

If repayment dates, interest or other terms change, retain the agreed variation and its effective date with the original loan documents. Update the payment and interest schedules accordingly, then reconcile them with the ledger. An informal agreement between connected parties can still require careful factual and tax analysis; familiarity between the parties does not remove the need for evidence.

Ask the adviser to consider any accounting and tax consequences of the change before treating it as a routine spreadsheet edit. Keep details of fees, waivers or amounts capitalised into the balance. This creates a coherent history of the relationship and helps later reviewers distinguish an ordinary payment delay from an agreed modification, release or other event that may need different treatment.

Illustrative scenario

A director lends funds to the company and later begins charging interest. The company records the agreement and interest calculations and asks the accountant about the relevant reporting and deduction position. It does not treat the entire repayment, including principal, as a new business expense.
