“As your turnover exceeded the registration threshold in March 2009 you should have applied for registration, or exception from registration, by30 April 2009 . When exception is applied for retrospectively it is only information that would have been available at the time the liability to register arose that can be considered. You explained … that you took your son on in March 2009 and that this was the cause of the rise in your turnover. I understand that your son worked with you until he started his own business in February/March 2011. It would appear from this information that, in March 2009, you could not have forecast a downturn in your forthcoming 12 monthly turnover and therefore exception from registration was correctly refused. In fact, your rolling 12 month turnover did not fall below the VAT registration threshold until August 2011 and you have now been de-registered with effect from31 August 2011 .”
