Problems you face, answered
It is a £1,000 tax-free allowance for miscellaneous trading income. If your side hustle income is under £1,000 a year, you usually do not need to pay tax on it or register.
You can either deduct the £1,000 allowance instead of your actual expenses, or deduct real expenses if they are higher, then pay tax on the remaining profit.
Yes. Your PAYE job usually uses up your personal allowance, so side hustle profit is often taxed at your marginal rate straight away, commonly 20% or 40%.
If your side hustle income is above £1,000, you generally need to register for Self Assessment and file a return.
Class 4 National Insurance applies to self-employed profit above the threshold, on top of any Class 1 NIC already deducted from your salary.
You can compare using the £1,000 trading allowance against entering your actual allowable expenses, and it shows which gives the better result.
The £1,000 trading allowance generally applies once across all your self-employed and miscellaneous income, not per activity.

Tax explained
How side hustle tax calculator works
The trading allowance lets you earn up to £1,000 a year from self-employed or casual income without paying tax on it or needing to register, provided your only income of this kind is below that figure.
Once your side hustle income exceeds £1,000, you generally need to register for Self Assessment, even if the tax owed turns out to be small.
You then choose between deducting the £1,000 trading allowance or your actual business expenses, whichever gives you a lower tax bill.
Because your PAYE job typically uses your full personal allowance of £12,570, side hustle profit is usually taxed at 20% or 40% from the first pound of profit.
You may also owe Class 4 National Insurance on the profit, separate from the Class 1 National Insurance already taken from your salary.
HMRC increasingly receives data from platforms directly, so it is worth checking your position with this side hustle tax calculator rather than assuming small amounts go unnoticed.

Expenses
Side hustle expenses vs the trading allowance
Allowable expenses only come into play once you choose not to use the £1,000 trading allowance, since a side hustle can claim one or the other but never both. If your real costs — stock, software, mileage or a share of home running costs — are modest, the flat allowance is usually simpler; once they run higher than £1,000, claiming actual expenses through self assessment normally leaves you with a smaller tax bill. Run both scenarios through this checker before deciding, and see our side hustle tax page for the fuller rules.
Usually claimable
- Materials, stock or ingredients bought for the side hustle
- Platform, marketplace or payment processing fees
- Software and apps used specifically for the work
- A fair share of home costs if you regularly work from home
- Postage and delivery costs
- Business mileage at HMRC rates
Usually not claimable
- The trading allowance and actual expenses in the same tax year for the same trade
- Personal items also used privately, without a fair split
- Your regular commute to a main job
- Everyday clothing bought for general use
- Fines, penalties and purely personal subscriptions
If you are not sure which option comes out cheaper, run your figures past us or work through the creator expenses checklist first.
How HMRC’s rules apply to content creators
If you are self-employed
Self-employed costs must be incurred wholly and exclusively for your trade. If you use the £1,000 trading allowance, you cannot also deduct actual expenses against that same income. Equipment treatment depends on cash basis or traditional accounting.
If you run a limited company
A limited company deducts costs incurred wholly and exclusively for its business. Equipment may need capital allowances rather than an immediate expense deduction. Personal use or company-paid private costs can create a taxable benefit or director’s loan entry; company ownership is not a blanket deduction.
For separable mixed-use costs, such as a phone bill, claim only the identifiable business proportion and keep evidence. This does not make ordinary clothing or every dual-purpose purchase deductible. A receipt alone does not prove a business purpose: retain the brief, invoice or usage record too.
Costs to review for your work
- Business-use cameras, lighting, audio equipment and editing software
- Editors, thumbnail designers, virtual assistants and licensed music
- Travel to business shoots and the evidenced business share of home-working costs
Everyday clothing, ordinary grooming, personal meals, private gaming and fines are generally not deductible. Qualifying costumes or protective clothing and business-travel subsistence have different rules. Client entertaining is generally disallowed. Receiving a product from a brand does not automatically create an expense: record the income treatment separately and deduct only an allowable business cost.
