Hobby vs Trade Calculator 2025/26

Use HMRC's 9 badges of trade to determine whether your activity is taxable as a trade or remains a non-taxable hobby. Includes tax implication summary and £1,000 allowance check.

9 Badges of Trade Assessment

Answer each question based on how your activity actually operates. The more "Yes — trade indicator" answers, the more likely HMRC would class your activity as a trade.

1. Profit motive

Do you undertake the activity with the intention of making a financial profit?

2. Number of transactions

Do you buy and sell regularly, with repeated transactions (rather than a one-off or occasional sale)?

3. Nature of the asset

Is the asset a commercial/trading type asset (e.g. stock, bulk goods) rather than a personal enjoyment item you happen to sell?

4. Modifications before sale

Do you improve, process, repair or otherwise add value to items before selling them?

5. Connection to existing trade

Is this activity related to your existing main business, employment, or professional expertise?

6. Use of borrowed funds

Did you borrow money specifically to fund the purchase of goods or assets that you then sold?

7. Time interval before sale

Do you typically sell items within a short period after buying them (quick turnaround rather than long-term holding)?

8. Reason for sale

Are sales driven by opportunity and profit-seeking (rather than personal financial need or disposing of unwanted personal items)?

9. Supplementary operations

Do you advertise, maintain a website, use a business name, or actively market what you sell to attract customers?

What Are the Badges of Trade?

HMRC uses the concept of "badges of trade" to determine whether an individual's activity constitutes a trade for tax purposes. If the activity is a trade, profits are subject to Income Tax under ITTOIA 2005 and National Insurance contributions. If it remains a hobby, income is generally not taxable (subject to the £1,000 trading allowance check).

The badges were developed through case law, particularly the case of Marson v Morton (1986), which identified the key indicators. No single badge is conclusive — HMRC weighs all factors together. Some badges carry more weight in specific circumstances.

The test is particularly relevant for individuals who sell goods online (eBay, Etsy, Vinted), buy and sell collectibles, rent out assets, provide freelance services, or engage in any activity that generates regular income alongside a main job.

The £1,000 Trading Income Allowance

The trading income allowance allows individuals to earn up to £1,000 from trading or miscellaneous income per tax year without paying Income Tax or National Insurance and without needing to register for Self Assessment. If total income from all such activities exceeds £1,000, the excess is taxable (or you can choose to deduct actual expenses instead of the allowance).

This allowance exists independently of the hobby vs trade distinction. Even if your activity is formally a trade, you may not need to register with HMRC if your total trading income is under £1,000. However, once income grows, registration becomes necessary and the full badges of trade analysis becomes relevant.

Frequently Asked Questions

The badges of trade are 9 indicators HMRC use to determine whether an activity amounts to trading. They include profit motive, frequency of transactions, nature of the asset, modifications before sale, connection to existing trade, use of borrowed funds, holding period, reason for sale, and supplementary operations.
If your activity is classified as a hobby, income is generally not subject to Income Tax. However, if total income from the hobby exceeds the £1,000 trading income allowance, you may still need to declare it. The key test is whether the activity constitutes trading.
The trading income allowance allows individuals to receive up to £1,000 of trading or miscellaneous income per tax year without paying Income Tax or National Insurance. If income exceeds £1,000, the full amount is taxable (or deduct actual expenses instead).
There is no fixed threshold. HMRC weighs all 9 badges together. 6 or more positive indicators strongly suggest trading, 3-5 is borderline, and 0-2 suggests a hobby. The actual determination depends on the strength of each indicator and overall circumstances.
Yes. If an activity that started as a hobby develops commercial intent, regular transactions, advertising, and profit-seeking behaviour, HMRC may reclassify it as a trade. The point of reclassification affects when tax obligations begin.
If HMRC decides the activity was a trade, you may owe unpaid Income Tax and National Insurance contributions on profits, plus interest and potentially penalties. HMRC can typically investigate up to 4 years back for innocent errors and up to 20 years for deliberate evasion.
Yes. HMRC has confirmed that regular buying and selling on platforms like eBay, Vinted, Etsy or Facebook Marketplace can constitute trading if the badges of trade are met. Casual one-off sales of personal items (e.g. second-hand belongings) are generally not taxable.
Yes. HMRC applies the badges of trade test to cryptocurrency activity. If you regularly buy and sell crypto with the intent to profit, it may be classed as trading income rather than capital gains, which is also subject to National Insurance contributions.
If the activity is classed as a trade, you can deduct qualifying business expenses. If it is a genuine hobby, income is generally not taxable (subject to the £1,000 allowance check), so deductions are not relevant. You cannot use hobby losses to reduce other income.
You only need to register for Self Assessment if your trading income exceeds £1,000 in a tax year, or if HMRC considers the activity a trade. If income is genuinely a hobby and under £1,000, no registration is required.
Online course creators, YouTubers, bloggers, and social media influencers who earn income regularly with profit motive are generally classed as trading. This income is subject to Income Tax and National Insurance contributions as trading income.
Keep records of all income, expenses, purchases and sales (dates, amounts, descriptions), communications showing business intent, advertising evidence, and any other evidence of trading activity. Good records protect you whether HMRC decides it is a trade or not.
