Tax overhaul threatens US firms with four-year cash drain but could boost global mergers


US law firms are facing a fundamental overhaul over the way they calculate and distribute their profits that could result in far higher short-term tax bills if controversial proposals currently before Congress are approved.

The proposals could see US firms with over $10m in revenues forced to switch their accounting model from a cash basis, under which money received in a financial year is taxable, to a UK-style accrual method, where taxable revenue includes work done but not yet billed or collected.
