Tax principles The Credit Suisse Tax Principles set out our approach on tax matters:  Credit Suisse is committed to ensuring that its tax affairs are conducted in compliance with all applicable tax laws and practices, and will engage with tax authorities in a cooperative and transparent manner.  Credit Suisse will only undertake on its own behalf, or facilitate for clients or third parties, tax planning and transactions which support genuine commercial activity or which we believe to be consistent with the relevant tax authorities’ expectations and practice.
