Douglas - the accounting firms have specialist tax consultancy practices that help businesses with tax planning and minimising their tax bills, but this is not mainstream consulting work and is not typical of the type of assignment you'd work on in a business consultancy. You're more likely to be advising a client on the strategic direction of their business, or how to outsource a part of their business functions, or placing a monetary value on a potential acquisition target based on the synergies that exist with the business.In terms of tax on your own remuneration, a few firms have experimented with clever bonus schemes that help to reduce the %tax bill you as a consultant will face. But by and large you should expect your basic salary to have national insurance and income tax deducted without any fancy footwork - and if you don't pay 40% tax + national insurance on your bonus then you're also one of the lucky few.If you join a very small firm where you actually become a shareholder then you might receive dividends as well as salary - and these do attract a lower % rate. But I can't imagine this would be your primary reason for joining a very small firm!Tony
