Banner showing a stamp of the Fair Tax Mark - the world's first responsible tax certification

We are the Fair Tax Foundation and we believe companies demonstrating responsible tax practices should be recognised and celebrated, and any global race to the bottom on corporate income tax resisted.

Our Fair Tax Mark certification is the gold standard of responsible tax conduct and certifies that a business:

– seeks to follow the spirit, as well as the letter of the law

– shuns corporate tax avoidance such as the artificial use of tax havens

– is transparent about profits made and taxes paid

From small grocery stores in the UK to large listed multinational energy companies across Europe, the Fair Tax Mark label is increasingly displayed by business of every size and shape.

Fair Tax Mark accreditation has now been secured by 275 businesses, which together employ more than 475,000 people and contribute £4.1bn / €4.8bn annually in corporate income tax worldwide. Our progressive community has grown to embrace businesses headquartered in the UK, Denmark, Germany, Finland, Italy, Spain, Sweden and the Netherlands.

From building trust with customers to staying ahead of regulation, Fair Tax Mark certification will help you to stay ahead of competitors.
