Build computation
Build the corporation tax computation for last accounting period for this client in Xero, working from the audited trial balance. Start from accounting profit, apply add-backs for disallowed expenses, depreciation and entertainment, deduct capital allowances and apply the corporation tax rate including marginal relief where in band. Track losses brought forward and losses available for carry-back. If a disallowed expense is new or unclear, ask me whether to follow the prior year or open a fresh entry. Pause before locking the computation. Ask me where the practice keeps the client's tax memorandum. Save the computation and working papers to Google Drive ready for senior review.
Claim allowances
Maintain the capital allowances pool for this client in QuickBooks and apply this year's claims. Carry forward the main rate, special rate, single-asset and short-life pools from the prior year, add this year's additions per supplier invoice and check the AIA eligibility. Apply full expensing for qualifying plant and machinery on the main pool. If an asset's classification is unclear or the client has not flagged a disposal, ask me whether to chase the client or to assume continuity. Pause before crystallising a balancing allowance. Save a note for the practice manager listing claims proposed, items awaiting client confirmation and any pool movements that need senior review before the CT600 is finalised this period.
Tag iXBRL
Apply iXBRL tagging for this client's statutory accounts and tax computation in Sage 50 using the current FRC Detailed Tagging List. Tag every primary statement, every note required by the DPL and every accounting policy disclosure. Validate the tagging against the FRC schema, check mandatory tags are present and review recommended tags against the practice's tagging policy. If a disclosure cannot be tagged automatically and a custom tag is needed, ask me before adding it. Pause before locking the iXBRL package. Ask me where the practice files the prior year's tagged accounts as the reference master. Save the tagged accounts and validation log to Google Drive ready for the CT600 submission attachment.
Submit to HMRC
Submit this year's CT600 to HMRC for this client from FreeAgent through the practice's Agent Services Account. Attach the tagged statutory accounts, the tax computation and any required supplementary pages (CT600A directors loans, CT600C group relief, CT600L R&D additional information). Confirm the receipt reference returned by HMRC, schedule the corporation tax payment for the due date and reflect the liability in the ledger. If HMRC returns a validation error, read the error and prepare the correction for senior review. Pause before resubmitting. Ask me where the practice files the receipt evidence. Save a note for the practice manager listing submission status, receipt reference and payment timing.
