Consulting on the side of PAYE job

[oilboil]

Whilst all input appreciated, I'm fully aware of the situation and this is not an issue for me or my employer, although I appreciate it could be in many industries/companies.

Cool - if you know the potential pitfalls and your main employer doesn't have an issue then that changes it.

Normally it would be pointless to do a LTD company for 30K yearly income as the whole amount could just go out in salary etc for little tax imposition.

In your position though I'd go LTD and just leave the cash in the account until you decide to take a sabbatical from your main job (or decide to leave and go back to contracting where you'd have a starter war chest already built).

Yes you'll lose 19% (and a few pennies in filing charges) for Corp Tax but that's less than PAYE on the extra 30K
