Integrated cases: reading a tax note, cash tax versus effective tax

A tax note lets you split a change in the effective rate into geographic mix and one-off items, and tie cash taxes to the movement in the net deferred tax balance, so each rate is used for the question it answers.

In short

  • Compute both rates for every year: effective = total tax expense ÷ pretax income; cash (proxy) = current tax ÷ pretax income.
  • The gap between them is the deferred tax expense, which equals the change in the net deferred tax liability (ignoring rate changes and acquisitions).
  • Explain a falling effective rate in two parts: the profit mix across countries (blended statutory rate) and everything else (allowance changes, credits, one-offs).
  • Look at each country's own current and deferred tax: a deferral lowers the cash rate and reverses later, but never changes the effective rate.
  • A valuation allowance release lowers tax expense but is not cash and is not a forecastable operating gain.
