Corporation Tax / CT600
Corporation Tax / CT600 Filing
All UK-registered companies are legally required to file their annual accounts with Companies House and submit a Corporation Tax Return (CT600) to HMRC. Both authorities have strict and often complex filing deadlines, and missing them can result in instant penalties.
For many business owners — especially those new to accounting and compliance — the process can be confusing and overwhelming. Even accounting students find the CT600 filing system challenging at the start, so it’s no surprise that busy entrepreneurs struggle to manage it alongside running their businesses.
