Help doing my self assessment

deanbwfc

Hi, i'm just looking for help doing my online self assessment before 31 Jan, got a few things i'm not sure about.....
I'm a self employed plumber and starting working self employed in May 2010, i've got all my inoices and receipts together and ready to do the tax return. First of all i bought a van in June 2010 (got the invoice) and basically my wealthy uncle paid for it and i pay him back £30 a week, how would i treat this on my return?
After looking through the HMRC notes i understand that i need to try and split how much i use the van for work and how much i use it for private, i would say as an estimate 70% work 30% private. The bigger issue is the mileage i've got all my petrol receipts but i'm not sure how many miles i did per job (i will note this down in future) so i do around 12,000 miles a year, is it acceptable to split the 12,000 miles by 70% and so claim 40p for 8,400 miles for work?
Mobile phone top ups, again i use most of these for work and 70% would be about right, do i claim 70% back as expenses?
The insurance on the van (£90 a month) do i count this as expenses to be claimed back in full?

Within the year i paid in £1,900 from a whip last claim from a couple of years ago, would i count this as income?

Thanks for your help

Dean, most of the people who are trying to complete their SA post in the Cutting Tax board so maybe you should go there too. I am sure one of the HMRC experts there will help.
