Tax is not a return

A tax benefit may reduce a tax bill. It is not the same as an investment return and does not automatically make a product suitable.

In more detail

Cost, risk, access and the timing of tax remain separate questions. “Tax-optimised” without those is a marketing word, not a measure of return. Finmon does not compute a net return at your tax rate from that.

Background

Marginal rate, tax base, loss offset and later taxation can reverse today’s benefit. Jurisdictions differ; German Abgeltungsteuer is not a UK ISA. P0: a tax saving is not a return.

An example

Two offers: 4% before tax with no relief, 3% with an advertised tax effect. Without risk, costs and later tax, the saving alone does not say which result is better.

A common misconception

A tax saving is a return.

Tax changes a levy. It replaces neither return nor suitability.
