My husband and I both work for the NHS. He works F/T, I work only 2 days per week. He is a higher-rate tax payer, I'm not.
We both also do locum (contractor) work and pay ourselves though limited companies where we pay tax on a minum wage and draw the profits as a dividend.
We both have NHS salaries which are taxed at source through PAYE.
My total income does not exceed £30k. His total income is well above this.
I know he's paying the right amount of tax via PAYE but how do we know he won't get stung for a tax bill if he has to complete self assessment?
