I have to file a return by Oct 31 and I've fallen at the first hurdle trying to register for ROS as I don't know what category I fall into. In 2005, I worked part of the year as PAYE. Then I worked for a UK company which didn't deduct tax but paid me gross - so I owe income tax and health levies for this. The UK company has now registered as an employer etc. so I'm PAYE again in 2006. WHen I try to register for ROS, what is my tax type/approval number? Most obvious options are Paye-Emp or Income Tax - but I'm not sure which one. Also, it asks for Regn. No/ID no - do I put by PPS number in here? Thanks.
