Frequently Asked Questions
Answers to common accounting and bookkeeping questions from UK business owners
What is the deadline for filing Corporation Tax returns in the UK?
Corporation Tax Returns (CT600) must be filed with HMRC within 12 months of the end of your company’s accounting period. However, Corporation Tax payment is usually due 9 months and 1 day after the end of the accounting period. We ensure both filing and payment deadlines are met to avoid penalties and interest.
Who needs to submit a Self Assessment tax return?
Self Assessment tax returns (SA100) are required for individuals such as Company Directors, Sole Traders, Freelancers, Contractors, Landlords, and High Net Worth Individuals — or anyone with additional income not taxed at source. If you are unsure whether you need to file, we can assess your situation and advise accordingly.
Can you help reduce my tax liability legally?
Yes. We focus on lawful tax efficiency by reviewing allowable expenses, capital allowances, reliefs (such as R&D claims where applicable), and optimising your tax position within HMRC regulations. Our approach ensures compliance while minimising unnecessary tax exposure.
4. Do you deal directly with HMRC on my behalf?
Yes. We can liaise directly with HMRC regarding your Corporation Tax, Self Assessment, or Partnership Tax matters. This includes handling queries, clarifications, and submissions — providing you with professional representation and peace of mind.
