Many people take advantage of the Christmas season to earn extra income. Whether you design festive cards, sell handcrafted decorations at local markets, or list second-hand items online, the holiday period often provides a welcome financial boost. Content creators and influencers may also receive Christmas gifts from brands in return for promotional posts. For many individuals, these activities feel casual and informal rather than commercial.
However, HMRC takes a clear view on the matter. If you are generating income with an intention to profit, even on a modest scale, you may be treated as running a business for tax purposes. Understanding when a hobby becomes taxable activity is essential, particularly during the busy festive season when sales and gifting arrangements can increase.
This article explains how HMRC assesses casual income, when you need to register for tax, and the points you should consider if you are earning extra money this Christmas.
HMRC’s “Help for Hustles” Campaign
HMRC has committed considerable energy to raising awareness among individuals who earn money outside their main job. The “Help for Hustles” initiative focuses on people who sell goods or services in their spare time, whether regularly or only during certain parts of the year. The campaign emphasises a straightforward message: if you aim to make a profit, your activity may be taxable.
Examples include:
- Selling handmade festive decorations
- Running a Christmas market stall
- Tutoring, pet sitting or dog walking
- Baking seasonal treats to order
- Reselling items online
- Content creation or promotion in return for gifts or payments
The trading allowance offers up to £1,000 of tax-free income each tax year from casual trading. Anyone earning more than this must inform HMRC. The threshold applies to gross income, not profit, so even if your costs are high, passing the £1,000 limit means you may still need to report the activity.
HMRC uses various methods to identify individuals who may be trading, including information received from online platforms and from reviewing publicly available social media content. Letters may be issued where HMRC believes undeclared income exists.
How Online Platforms Share Seller Information
From December 2024, HMRC confirmed that platforms such as eBay, Etsy, Amazon, Airbnb and Deliveroo must share specific data about sellers and service providers. This development has made it easier for HMRC to spot potential trading activity.
The information provided includes:
- Name, address and date of birth
- National Insurance number
- Number of transactions
- Total sales proceeds
Reporting applies when a seller either completes 30 or more transactions in a year or earns more than €2,000 (around £1,700) in gross sales. Platform operators must also give the seller a copy of the data supplied to HMRC.
This system does not introduce new taxes. Instead, it offers HMRC greater transparency to ensure existing rules are followed. Seasonal traders and casual sellers should therefore assume that their activity is visible to HMRC.
Deciding Whether Your Activity Counts as Trading
Not every sale triggers a tax obligation. Selling unwanted personal belongings generally falls outside the scope of trading. The distinction lies in intent and behaviour. HMRC uses the well-established “badges of trade” to decide whether an activity is a trade rather than a hobby.
The Nine Badges of Trade
HMRC’s Business Income Manual lists nine indicators:
- Profit motive
- Number of transactions
- Nature of the asset
- Similarity to recognised trading activity
- Modifications to the asset before sale
- Method of sale
- Source of finance used to buy the goods
- Time between purchase and sale
- Method of acquiring the item
A single badge may be enough for HMRC to classify activity as trading, although some carry greater weight depending on the circumstances. For example, buying craft supplies specifically to create products for sale, or purchasing goods with the intention of reselling them at a profit, provides a stronger indication of trading than selling a few unwanted household items.
If HMRC concludes that your activity fits within these trading indicators, the income is likely to be treated as taxable and must be declared.
Understanding the Trading Allowance
The trading allowance permits up to £1,000 of trading income each tax year without the need to report it. If you earn less than this amount, HMRC does not expect a tax return solely on the basis of that income.
When income exceeds the £1,000 threshold, you can either:
- deduct the allowance from your gross receipts, or
- deduct actual allowable expenses that relate wholly and exclusively to the activity.
Choosing which approach is more beneficial depends on the level of your costs. If your expenses exceed your income and a loss would arise, it may be sensible not to use the allowance. Instead, you may prefer to claim the loss, which could reduce your overall income tax bill.
Tax Rules for Influencers and Non-Cash Benefits
Many influencers and content creators receive items such as clothing, food or festive products in exchange for promoting a brand or reviewing an item. These rewards count as trading income and must be declared. The taxable amount is the value of the item received.
If payments are also received alongside gifts, both must be included in the total trading income. Failure to declare non-cash benefits can create tax issues later, particularly because brands and agencies may keep records that HMRC can access if needed.
How HMRC Helps Individuals Assess Their Position
To assist casual earners and seasonal sellers, HMRC has created an online tool to help determine whether additional income needs to be reported. Different scenarios are explored, including occasional selling, service-based activity and content creation.
Although these tools provide guidance, they do not replace tailored advice. If your activity sits somewhere between a hobby and a business, professional support can help you understand how the rules apply to your situation.
Preparing for the Christmas Season
If you plan to sell items or create content over Christmas, consider the following steps:
- Keep basic records of sales and any associated costs
- Track the number of transactions and total sales income
- Retain receipts for materials or goods purchased for resale
- Keep a record of any non-cash gifts received in exchange for promotional activity
- Check whether you are likely to exceed the trading allowance
- Consider whether your behaviour suggests a profit-making intention
Paying attention to these points early in the season will help you avoid unexpected tax issues later in the year.
When You Should Register with HMRC
If your income from side-hustle activity exceeds £1,000, you will need to register for self assessment. Registration deadlines depend on the tax year in which the income arises. Once registered, you must complete an annual tax return and pay any tax and National Insurance due.
