I have a regular job and a normal income from it - an annual salary taxed as PAYE.
I do some extra work that brings in a modest income but isn't anything like a primary job and the income is irregular. Let's say it's polishing housebricks on an ad-hoc basis.
I believe I then need to declare this extra income on a tax return.
However, if polishing house bricks were a regular job, I understand I could claim tax exemptions on things like my phone which is needed for contacting potential clients who need bricks polished, and my polishing kit, which is clearly essential. Effectively I'd be declaring myself to be a housebrick polisher.
If housebrick polishing isn't my full time or primary job, though, can I still claim those costs? And how much is reasonable before you get into MP-duckhouse territory? Can I claim on anything peripherally related to the polishing, even if I'd have bought it anyway? What if the items far outweigh the income generated by brick polishing?
