QUESTIONS regarding tax return (1st time...!)

[Hollyhock]

Hi,

I'm trying to sort out my very first tax return and, in spite of having read various very helpful guidelines, I still have a few questions. If any of you could answer some, I would be so grateful!
I am using the fabulous worksheet by happytoddlers:

- how do I list all the purchases for which I don't have a receipt (e.g. bought on gumtree)?

- how precise do I need to list food expenses? Do I have to divide the cost of a pack of flour into portions of bread etc...?? (it seems silly to me, but it's the first time I'm doing this...)

- there are 3 shifts on the spreadsheet - is this possibly not relevant for everybody and if so, can I just use one of the three columns, and ignore the other two?

- in the column "receipt number", do I just number the receipts (1, 2, 3...) or do I have to enter some number that can be found on a receipt...? (I told you it's the first time I'm doing this!)

- where do I have to list the start-up grant money?

- do I have to list money I was given/lent by my friends and my parents?

- how do I list up the monthly rent (amongst expenses I assume, but what do I write into "receipt"? I don't get a receipt from my landlord, and I pay cash)?

- how do I lest wear and tear (I read it's 10% that we can claim)?

- the first sessions I was paid for in cash, and unfortunately didn't keep any records...will my (signed) attendance register suffice to show how many hours I was paid for?

- does the time spent cleaning up, planning, shopping, cooking and baking in preparation as well as paperwork count as work hours, or not? I found varying advice regarding this (I think in one of the HMRC webinars it was said that work time does include the above).

- I'm going to fill out the online tax return. Will I have to attach digital photographs of all the receipts??
