My wife is already registered as self employed (not window cleaning), she earns over the ni limited but under the tax threshold. Im a sole trader and the wife's work circumstances may be changing so i'm thinking of paying her (say £75 per week) to come out one day a week to make up for the loss of earnings in her existing self employment. This would bring her annual pay to pretty much the same as it is now ie under the tax threshold but over the ni limit. Idealy i would like her just to declare this as self employment income as she does now and down in my accounts as an expense. For those who employ their spouse ,can i please ask, is this possible or do i have to go down the route of paye? I will of course contact Hmrc but not contactable today and there's a lot contradictory advise out there on line, cheers in advance.
