Company accounts & CT600

Corporation Tax Accountant Manchester for Limited Companies

Statutory accounts and the CT600 are connected, but they are not the same calculation. Accounting profit must be reconciled to taxable profit by adjusting for expenditure, capital allowances, losses, associated companies and other Corporation Tax rules.

A strong year-end process reconciles the balance sheet before the tax computation begins. Unexplained director balances, payroll differences, VAT control accounts or unreconciled bank items should not simply flow into a filed CT600.

Direct answer

What Does a Corporation Tax Accountant Manchester Review Before Filing?

The accounts, tax computation and CT600 should reconcile to one another and to the underlying company records.

The practical answer

A Corporation Tax Accountant Manchester Should Reconcile the Accounts Before the CT600

Corporation Tax is calculated from taxable profits, not simply the profit shown at the bottom of the statutory accounts. Tax adjustments, allowances and reliefs need to be supported by the records.

Accounting profitStarting point from the company's financial statements.
Tax adjustmentsNon-deductible and separately relieved items are identified.
Capital allowancesQualifying assets receive tax relief under the capital-allowance rules.
LossesCurrent and brought-forward losses may affect taxable profits.

Frequently asked

Corporation Tax Questions

Is Corporation Tax based on the profit in the accounts?

The accounting profit is the starting point. Tax adjustments, allowances, reliefs and losses are then applied to calculate taxable profit.

When is Corporation Tax due?

For most companies outside the instalment-payment regime, payment is normally due 9 months and 1 day after the end of the accounting period.

When is the CT600 due?

The normal filing deadline is 12 months after the end of the Corporation Tax accounting period.

Does a loss-making company still file a CT600?

If HMRC has issued a notice requiring a Company Tax Return, the company normally still has to file even where no Corporation Tax is due.

What is an associated company?

Associated-company rules can apply where companies are under common control. They can alter the thresholds used for the small-profits rate and marginal relief.

Can you take over incomplete company accounts?

Yes, subject to the condition of the records, professional clearance where applicable and an agreed scope for reconstruction work.
