The OECD is to issue its report on the relationship between tax authorities and advisers today. As Accountancy Age reports:

The broad conclusions of the report, commissioned by the OECD, are expected to be that tax advisers to facilitate avoidance in some cases, but that the ultimate responsibility for tax planning lies with the taxpayer.

Maybe, but I'll be candid: I think that's a cop out. And I think the OECD knows it because it also says:

The report will also call on revenue bodies to implement robust risk management strategies and implement structures that require the early disclosure of any tax planning schemes.

And who writes them? The practitioners, in the main.

That's why our Code of Conduct explicitly recognises there are three in this marriage: anything else will not do.
