Thanks for your response
I have answered fully and then offered assistance to take the matters further
I advised "But diesel yes, as this takes you to and from the locations, so work out your mileage undertaken and you can claim 45p a mile for the first 10,000 miles and then its 25p a mile for any mileage in excess of that threshold. And any overnight stays, so the cost of the overnight stay and any subsistence for breakfast. And yes the agents commission is an allowable expense too Any insurances you might have are allowable, as are the costs to travel to apply for a film extra role (and any admin such as stationary stamps telephone, internet use - if you search and apply online) and any magazine purchases you make for job advertisements. And I asked if you wanted any help calculating these then let me know, I also advised what you were not permitted to claim (that you had been given the impression that you could) and the reason why. I am also ex HMRC - having provided education to self employed individuals such as yourself and have worked self assessment for the self employed for 32 years both in HMRC and since 2008 from my own accountancy firm, and whilst I do not want to discredit your friends husband see this link from the business income manual that states hair and clothes are NOT permitted (unless the clothes are safety wear, uniform or logo'd)
If its a period piece, for example
then this can be allowable as you would not wear Elizabethan clothes in your normal day to day life.
And as you have not completed any forms, you should have registered for self assessment within 3 months of this film extra work beginning, so you need to remedy this as a matter of urgency - then you can declare the income (all income, so pensions and this income from being a film extra) and the expenses incurred, which I am happy to advise further on (as already stated)
The mention of the £2500 relates to the amount of expenses to be claimed and is pertaining to the year in question (not an advanced guess) but the P87 form should NOT be completed by you, as you are NOT an employee you are self employed, and so MUST complete self assessment - which I also have already advised
So keeping this simple
1) You can claim for mileage - and I have advised how
2) You can claim for any insurances you have to provide this work
3) You can claim for administrative costs, stationary, postage, telephone and internet (if this is used) and if you need help with this then please advise - I can calculate this for you if you need
4) Magazine purchases to apply for roles
So I am advising HOW this must be undertaken - which is through self assessment as you are self employed - I have covered what you cannot claim as you raised these as a claim issue and I have advised why you cannot claim these (and when you can claim those I have said no to) - I have advised what could be claimed - if you actually incur those expenses, and offered help with how to calculate these, and I have advised on ALL the other points you raised.
I would very much like to help, but lets sort out about what you actually pay out to do this work - and whether the clothing is specialised, and what other out of pocket expenses.
I am sure you can appreciate, with a loaded question, asking for a open request for assistance - I have to explore what you might spend out before offering concrete direction on whether you can claim this back AND how to do this. Thanks
