Interest income in a limited company

Interest received by a company should be identified separately from trading sales, loan principal and distributions. Keep statements and the underlying agreement where relevant. Tax treatment and timing depend on the nature of the company and the applicable rules, so do not rely only on the date cash reaches the bank.

Review bank interest, interest on loans to others and any overseas deductions separately. Identify connected borrowers and unpaid interest. A company otherwise described as non-trading may still need its tax position reviewed when it receives income; labels should follow the facts.

Identify the source and legal recipient of interest

List bank accounts, deposits and loans generating interest for the company. Separate interest from repayment of principal, trading sales and dividends. Confirm the account holder and contractual recipient. A director's personal savings account is not a company account merely because company money was transferred there, and such an arrangement needs its own review rather than automatic inclusion in ordinary bank interest.

HMRC's loan relationship guidance explains the framework for relevant corporate finance credits and debits. ^[1] Provide the accountant with the nature of the arrangement and accounting evidence. Do not assume interest is taxable only when cash arrives or that every finance return has identical treatment. Keep the relevant terms, statements and calculations so timing can be assessed properly.

Reconcile gross amounts, deductions and accruals

Obtain statements showing interest credited, accrued and any tax deducted. Reconcile the figures to the bank and ledger. A net receipt may need a gross amount and separate foreign or other tax analysis. Preserve the source document rather than estimating the deduction from the difference between two unexplained bank entries.

For fixed-term deposits, record the term, payment schedule and access restrictions. Check the year-end amount under the applicable accounting and tax rules. A deposit maturing after year end can still create a timing question before the cash is received. Keep the principal balance separate so repayment of the deposit is not counted as new income when the product matures.

Review loans to others and connected arrangements

For a loan made by the company, maintain the agreement, borrower details, interest rate and payment history. Identify unpaid interest and the borrower's financial position. A decision to waive or vary interest requires review of the actual terms and consequences. Do not remove accrued amounts without documenting whether the issue is collectability, a contractual change or an error in the original calculation.

Use Tax records for company loans for the wider loan record and Recording a director loan account where directors or participators are involved. Connected parties may raise additional tax issues and evidence needs. Keep the commercial purpose and approval of the loan clear. A company should not describe personal support to an owner as routine treasury investment without assessing the real arrangement.

Check activity status and overseas elements

Interest can require a tax review even where the company is otherwise described as non-trading. HMRC's trading and non-trading guidance provides the context for assessing activity and obligations. ^[2] Do not continue using a dormant label without considering the actual income and relevant notices. Companies House and Corporation Tax positions may need separate examination.

For overseas interest, retain country, payer, currency and tax certificates. Use Overseas income received by a UK company for foreign-income records and possible double taxation relief. Foreign withholding does not automatically settle the UK tax position. Ask the accountant to distinguish gross income, exchange effects and any available relief under the relevant conditions rather than recording only the net sterling receipt.

For Corporation Tax record review, provide an account and loan schedule with statements and material terms. Ask for review of classification, timing and any connected or overseas issues. Keep the tax calculation linked to the supporting income schedule and update it when deposits mature or loan terms change. This makes interest visible as a distinct part of the company's affairs without confusing principal movements, cash timing and the taxable result.

Reconcile interest across multiple accounts

List each deposit or lending arrangement held in the company's name and obtain the relevant statements for the accounting period. Check accounts that were closed or moved during the year as well as those still active at year end. A statement from the main bank may not include interest earned through a separate savings provider or investment platform.

Reconcile the amounts to the ledger and identify timing, currency or withholding differences for review. Keep principal transfers separate from the return earned on them. Where an account is held jointly or through an unusual arrangement, establish the legal recipient and underlying facts before allocating income. This gives the tax preparer a complete starting point without assuming that every credit described as interest belongs to the same category or period.

Illustrative scenario

A company receives a payment from another group company that combines loan principal and interest. The accountant requests the loan schedule and separates the two components. The record explains the remaining principal balance and the income recognised, rather than classifying the whole receipt as sales or ignoring it as an internal transfer.

Preparation checklist

• Identify the source and nature of each interest amount.
• Separate principal, interest and other receipts.
• Keep statements, agreements and period calculations.
• Review connected parties, overseas tax and dormant status where relevant.
