Corporation Tax
Accurate corporation tax calculations and CT600 filings that keep your limited company compliant and tax efficient.
About our Corporation Tax service
Every limited company needs to calculate, report and pay Corporation Tax to HMRC — and the rules around allowable deductions, reliefs and rates can be easy to get wrong. We prepare your CT600 return alongside your annual accounts, identify legitimate reliefs (such as capital allowances and R&D where applicable), and make sure your payment deadlines are never missed.
How our Corporation Tax process works
Year-end information gathering
We collect your company accounts, bank records and any relevant documents for the accounting period.
Calculation and review
We calculate your taxable profits, apply available reliefs and allowances, and prepare your CT600 return.
Filing and payment guidance
We file with HMRC and Companies House where relevant, and let you know exactly what to pay and when.
Common questions about corporation tax
When does Corporation Tax need to be paid?
Normally nine months and one day after the end of your accounting period, while the CT600 return itself is due twelve months after the period end.
What expenses can my company claim?
Most costs incurred wholly for business purposes — including salaries, rent, equipment, professional fees and certain travel — can usually be deducted. We will go through your specific situation with you.
Can you also handle my annual accounts?
Yes, our year-end accounts and Corporation Tax services go hand in hand, so everything is prepared consistently and filed on time.
What if my company made a loss?
Losses can often be carried back or forward to reduce tax in other periods. We will review the best option for your circumstances.
