For corporation tax purposes, a company is classified as very large when its augmented profits exceed £20 million. This classification aligns with various tax thresholds that differentiate between different sizes of companies for regulatory and taxation purposes. The £20 million mark is significant since it affects how the corporation tax is calculated and what obligations the company has in terms of reporting and compliance.

The reasoning behind this threshold can also relate to the proportionate impact larger companies have on tax revenues, as well as the administrative complexity involved in managing and overseeing their tax obligations. Companies exceeding this profit level may be subjected to different regulations and potentially higher rates of taxation, reflecting their capacity to contribute more significantly to the public finances.

Understanding these thresholds is important for both tax practitioners and business owners to ensure compliance with tax laws and to adequately prepare for any potential tax liabilities.
