when exactly are tax return due? my wife has recently become self employed (7 months ago) and we have a second property which we rent out. This will be our first year filing tax returns. We have been in contact with an accountant earlier this year (he has the details) to do the returns and what i would like to know is should the accountant be getting in touch with us or do we have to get on to him? So far we havent heard from him.
