When should a small company review Corporation Tax?

The useful window is before the company year-end, when records, director payments, allowable costs and cash set aside for tax can still be reviewed properly.

Can Gardian reduce my Corporation Tax bill?

Gardian can review lawful planning points and record quality, but no accountant should promise a saving before checking the company facts, profit, evidence and current rules.

What records are needed for Corporation Tax?

Typical records include bank statements, sales invoices, supplier bills, receipts, payroll records, VAT returns, loan agreements, asset purchases and explanations for director payments.

Corporation Tax support that starts before the year-end scramble.

Gardian helps owner-managed limited companies connect annual accounts, CT600 evidence, director payments and tax cashflow so Corporation Tax is not treated as a last-minute filing exercise.

When to review What gets checked Records Planning boundaries FAQs

Year-end accounts

Prepare company accounts with clearer evidence for income, costs, assets, liabilities and director balances.

Corporation Tax return

Connect the CT600 to the accounts, payment timing and supporting records so directors understand what is being filed.

Director decisions

Review salary, dividends, loans, pension intentions and personal tax touchpoints before options become narrower.

Timing matters

The best Corporation Tax conversations happen before the accounting year closes.

After the year-end, an accountant can still prepare accounts and explain the tax position. But many useful planning questions rely on current records and enough time to check the facts safely.

Corporation Tax support

What Gardian would usually want to understand.

This is not about chasing every possible tax angle. It is about making sure the accounts are reliable enough for sensible, compliant decisions.

Area	What gets checked	Why it matters
Accounts evidence	Sales, purchases, bank activity, journals, assets, liabilities and any missing explanations.	The Corporation Tax return depends on the quality of the accounts behind it.
Director payments	Salary, dividends, personal spending, repayments and director loan account movements.	Mislabelled payments can create tax, paperwork and cashflow surprises.
Allowable costs	Business purpose, mixed-use costs, mileage, home-working, training, equipment and professional fees.	Claims need evidence and judgement, not guesswork or copied internet rules.
Tax cashflow	Corporation Tax payment date, VAT/PAYE timing and money set aside for upcoming liabilities.	Directors need to separate usable working cash from money already effectively committed.

Corporation Tax FAQs

Questions directors often ask before year-end.

When should Corporation Tax be reviewed?

Ideally before year-end, then again when accounts are being prepared. That gives time to improve records, understand director payments and plan cashflow before payment deadlines arrive.

Can tax savings be guaranteed?

No. Gardian can review lawful planning points after checking the facts, but a promised saving without evidence would be unsafe and misleading.

Is this only for limited companies?

Corporation Tax applies to companies. Sole traders usually need Self Assessment support instead, and growing businesses may also need VAT, payroll or bookkeeping help.
