Why HMRC Is Watching eBay Sellers

HMRC now receives sales data directly from online platforms and digital platforms. That includes platforms like eBay. So yes, eBay reports seller information to tax authorities.

This applies to online sellers, casual sellers, people earning additional income, full-time eBay sellers, and even those selling alongside traditional businesses. Hence, if you’re making money, then HMRC wants to know that. It is as simple as that, but having limited knowledge makes it more complex. Thus, one must know different tax codes and their application mechanism.

The Trading Allowance Explained

The trading allowance is £1,000 per tax year. If your total income from selling goods or services online stays below this, you may not need to register for self assessment.

But once your income goes over £1,000, you have new tax obligations. Other than that, you may need to pay tax and possibly complete a tax return. This applies even if eBay is just a side hustle or new side hustle tax situation.

Income Tax and Capital Gains Tax

Most ebay sales fall under income tax, not capital gains tax.

You pay income tax if you’re trading or selling items regularly. It also applies if you are earning other income from eBay. For that, you may need to file a self assessment or submit a self assessment tax return or to pay income tax on your taxable income

Capital gains tax only applies when selling individual items worth over £6,000, like rare collectibles.

So yes, sometimes you must pay capital gains tax, but it’s less common for everyday sellers.

Providing Services on eBay

It’s not just about physical items. If you’re providing services online, offering digital work, or selling services through eBay; then it may be about design, repairs and freelance tasks

That counts as services online income. This is fully taxable.

You’ll need to register for self assessment and declare it on a tax return. Also, this make sure that you pay the correct tax and there is no way around it.

Deducting Expenses Properly

Yes, people treat the 0T tax code as an emergency tax code. Though it is not always labelled that way. It’s used when HMRC needs clarity fast. It does not necessarily reflect your actual tax code or long-term tax position.

How to Check and Fix Your Tax Code

There is a good news though. It means that you can reduce your bill by deducting expenses.

Allowable expenses include:

  1. EBay fees
  2. Postage
  3. Packaging
  4. Buying stock
  5. Tools used to sell items

Only claim what relates to your selling activity. Keep records always as this helps lower your taxable income and your hustle tax bill.

  • penalties
  • backdated tax
  • interest

Conclusion
