Expat income declaration to UK IR.

"I gave my UK income as zero for the year before - wasn't asked about the overseas income on the tax credit form", is a classic. You're not related to the Maxwells by any chance?

Oct 05 is a little early for determining your 05/06 tax liability isn't it? How can you possibly know you "Left UK in Jul 05 permanently"?

Presumably, because the period Aug04-Mar05 is more than

181? days and this makes you UK resident for TY 04/05 and theoretically subject to tax on your world-wide income for this period.

AIUI, you can claim split-year treatment for the first part of the year when you weren't actually resident but you have to apply for this status by filling in the relevent section on the Tax return and as you haven't done this, the Tax office want to tax you on it.

do you mean TY 03/04?

Under-reporting of what?

Thanks for the advice - can I now claim split year treatment retrospectively for tax year 04/05>

Yes

Under-reporting of my income for Apr 04 TO Aug04. i.e. giveing a lower estimate than actual>

You do this on the 04/05 Tax Return which isn't due for return until Jan 06. You need the non resident extra pages (as well as the standard bits).

But with respect to what (request)?
