The wholly and exclusively test
The rule that decides whether a cost is deductible is that it must be incurred wholly and exclusively for the purposes of the trade. That phrase comes straight from the tax legislation and HMRC applies it to every claim. If a cost has a clear business purpose and nothing else, it qualifies. If it also serves a private purpose, it fails the test unless you can separate out the business part.
The word that trips people up is exclusively. A cost is not deductible just because it is helpful, or because you would not have spent it if you were not a creator. It has to be for the trade and not for you personally. A microphone you only use to record videos passes. A coat you wear on a shoot and also wear to the shops does not, because wearing it keeps you warm and decent, which is a private purpose, not just a business one.
Two ideas soften this. First, some costs can be split where there is an identifiable business proportion, which is apportionment, covered below. Second, the test is about purpose, not about whether the spending turned out to be worthwhile. A piece of kit you bought for the channel still qualifies even if the videos flopped.
Revenue costs versus capital spending
There are two kinds of business spending and they are treated very differently. Revenue costs are the day-to-day running expenses of the trade: software subscriptions, stock music, props you use up, travel to a shoot, your business proportion of broadband. You deduct these in full in the year you incur them.
Capital spending is money you put into things you buy to keep and use across several years: a camera, a laptop, lighting rigs, a lens, an editing PC. These are not deducted as ordinary expenses. They go through the capital allowances system instead, which spreads or accelerates the relief in a controlled way.
The reason the line matters is timing. A £40 monthly software bill is a revenue cost you deduct as you go. A £2,000 camera is capital, and you claim relief on it through capital allowances rather than dropping the whole £2,000 into one box as a running cost. Getting the two the wrong way round is one of the most common mistakes on a creator return.
Equipment and the Annual Investment Allowance
Equipment such as cameras, laptops, lighting and computers is plant and machinery, and you claim it through capital allowances. For most creators the relevant route is the Annual Investment Allowance, which gives 100% relief on qualifying plant and machinery up to £1,000,000 a year. In practice that means you can usually deduct the full business cost of your equipment in the year you buy it, the same effect as a normal expense, just under a different heading.
The £1,000,000 ceiling is far above anything a typical creator will spend, so the Annual Investment Allowance covers the realistic kit list comfortably. Where an item is used partly for private purposes, you claim allowances only on the business proportion, which links back to apportionment below.
Full expensing is a separate, more generous relief, but it is only available to companies paying Corporation Tax. If you trade as a sole trader, ignore full expensing and use capital allowances and the Annual Investment Allowance. The detailed equipment guide below works through camera gear, laptops and software step by step.
Apportioning mixed personal and business use
Plenty of what a creator spends sits in both worlds. Your phone takes business calls and personal ones. Your broadband powers uploads and Netflix. Your car goes to shoots and to the supermarket. These costs are not barred outright. You claim the business share and leave the private share out.
The way to do that is to work out a fair, honest proportion and apply it consistently. If you use your phone roughly 60% for the channel, you claim 60% of the bill. If a laptop is 80% work and 20% personal, you claim allowances on 80% of the cost. There is no official formula for most items, so the standard is that your split is reasonable and you can explain how you reached it if HMRC asks.
Keep a short note of how you arrived at each percentage and keep the receipts behind it. HMRC does not expect minute-by-minute logs for everything, but it does expect the split to reflect reality rather than rounding everything up to 100%. For working from home there is a simpler option, a flat rate based on hours, which the home-studio guide covers in full.
Records and what HMRC expects
Whatever you claim, you need to be able to back it up. Keep receipts and invoices, note what each cost was for, and record the business proportion where an item is shared. Digital copies are fine. The point is that if HMRC ever queries a figure, you can show the cost was real and was for the trade.
You report your total allowable expenses on your Self Assessment return, either as a single figure or broken into the categories on the form. Capital items go in the capital allowances section rather than with your running costs. Claiming carefully is not about being aggressive, it is about claiming everything you are genuinely entitled to and nothing you are not.
