# What Is a Trial Balance? UK Bookkeeping Guide

**A trial balance is a list of every general-ledger account and its debit or credit balance at a particular date.** In a double-entry system, total debits should equal total credits.

Accountants use the trial balance as the starting point for reconciliations, year-end adjustments, management accounts and statutory financial statements.

## What appears in a trial balance?

The report normally includes:

- account code and name;
- debit balance or movement;
- credit balance or movement;
- reporting date or period; and
- opening, period and closing figures where the software provides them.

Accounts commonly cover assets, liabilities, equity, income and expenses.

## Example trial balance

| Account | Debit | Credit |
| --- | --- | --- |
| Bank | £8,000 |  |
| Trade debtors | £4,000 |  |
| Equipment | £6,000 |  |
| Expenses | £7,000 |  |
| Trade creditors |  | £3,000 |
| Bank loan |  | £5,000 |
| Owner capital |  | £4,000 |
| Sales |  | £13,000 |
| **Total** | **£25,000** | **£25,000** |

The matching totals confirm arithmetic equality, not that every figure is correct.

## How is it created?

Each balanced journal posts debits and credits into ledger accounts. At the reporting date, the system calculates each account's net balance and places it in the debit or credit column.

Accounting software generates the report automatically. A spreadsheet-based system must control account codes, journals and opening balances carefully.

## Adjusted and unadjusted trial balances

An **unadjusted trial balance** is produced before period-end journals. It may not include accruals, prepayments, depreciation, stock adjustments, tax or corrections.

An **adjusted trial balance** includes approved year-end entries and becomes the basis of the final accounts. Some accountants also retain a post-closing trial balance after income and expense accounts have been closed.

## What errors does a trial balance detect?

Unequal totals can reveal:

- a one-sided journal;
- different debit and credit amounts;
- incorrect opening balances;
- a damaged spreadsheet formula;
- an incomplete import; or
- manual changes outside the controlled ledger.

## What errors does it not detect?

A balanced trial balance can still contain:

- a completely omitted transaction;
- the correct amount posted to the wrong account;
- an entry in the wrong accounting period;
- equal and opposite errors;
- a duplicated balanced journal;
- an incorrect accounting estimate; or
- a fraudulent but balanced entry.

Bank reconciliation, control accounts, invoice testing and analytical review are still essential.

## Trial balance and bank reconciliation

The bank figure in the trial balance is the book balance. It should be reconciled with the bank statement after accounting for genuine timing differences such as outstanding payments or deposits.

A matching debit and credit total does not prove the bank balance agrees with external evidence.

## Control accounts

Important trial-balance accounts should agree with detailed records:

- trade debtors to the aged customer ledger;
- trade creditors to the aged supplier ledger;
- VAT control to VAT Returns and HMRC;
- PAYE control to payroll submissions and HMRC;
- fixed assets to the asset register;
- loans to lender statements; and
- stock to quantity and valuation records.

## From trial balance to financial statements

After adjustments and review:

- income and expense accounts feed the profit and loss account;
- asset, liability and equity accounts feed the balance sheet; and
- ledger movements and classifications support cash-flow reporting.

## Review checklist

- Confirm total debits equal total credits.
- Compare balances with the previous period and budget.
- Investigate negative assets, expenses or unusual signs.
- Clear suspense and uncategorised accounts.
- Reconcile all external balances.
- Review old debtors and creditors.
- Check personal and director transactions.
- Post and document period-end journals.
- Lock the final period and retain the report.

## Frequently asked questions

### Is a trial balance a financial statement?

No. It is an internal ledger report used to prepare and check the financial statements.

### Why does software always produce equal totals?

Controlled accounting software prevents unbalanced journals. It can still contain incorrect, duplicated or omitted balanced entries.

### How often should it be reviewed?

Monthly review is useful for many businesses. At minimum, it should be fully reconciled before management accounts, VAT or year-end work relies on it.

## Record-keeping basis

HMRC requires accurate records capable of identifying business transactions. Companies also have statutory duties to keep adequate accounting records.

**Legal source:** UK companies must keep adequate accounting records under [section 386 of the Companies Act 2006](https://www.legislation.gov.uk/ukpga/2006/46/section/386).
