Corporation Tax Services in Oxfordshire | Potts & Co Accountants Ltd
All UK-based limited companies—as well as non-UK companies managed or controlled from within the UK—are subject to Corporation Tax on their trading profits and capital gains.
Managing company tax duties requires more than just submitting figures to HMRC. Limited companies have a legal obligation to calculate their taxable profits accurately for each accounting period, prepare supporting statutory accounts, and file a formal CT600 Corporation Tax Return within strict statutory deadlines.
At Potts & Co Accountants Limited, based in Middle Barton, we provide comprehensive Corporation Tax preparation, compliance, and planning services for small and medium-sized limited companies across Chipping Norton, Bicester, Oxford, and the wider Oxfordshire area.
Our Complete Corporation Tax Services
We handle every aspect of your company’s tax compliance and planning, ensuring your filings are accurate, fully supported, and submitted on time:
- CT600 Return Preparation & iXBRL Submissions: We draft your full Corporation Tax Return (form CT600) and convert your statutory accounts into mandatory iXBRL format for electronic filing with HMRC.
- Taxable Profit Calculations: We calculate your exact Corporation Tax liability by adjusting accounting profit for non-deductible expenses, capital allowances, and allowable tax reliefs.
- Capital Allowances Optimisation: We ensure your company claims 100% of available capital allowances—such as Full Expensing and the Annual Investment Allowance (AIA)—on plant, machinery, business equipment, and commercial vehicles.
- Corporate Tax Planning & Allowable Expenses: We review your operational structure to identify legitimate tax-saving opportunities, including Director pension contributions, allowable expense claims, and efficient profit extraction strategies.
- Loss Relief Claims: If your business makes a trading loss, we evaluate options to carry losses back against previous profitable years to secure tax refunds, or carry them forward to reduce future tax bills.
- HMRC Agent Representation: As your appointed corporate tax agent, we handle all official communications, enquiries, and correspondence with HMRC on your behalf.
Important Corporation Tax Deadlines
Failing to meet HMRC deadlines results in automatic financial penalties and interest charges. We ensure your business remains fully compliant with the two key deadlines every company director must manage:
- Payment Deadline: Corporation Tax is typically due 9 months and 1 day after the end of your accounting period.
- Filing Deadline: Your CT600 return must be submitted to HMRC within 12 months of the end of your accounting period.
