You earned a pittance, but you could pay a fortune! Online selling demystified.

Imagine you're selling small items on eBay, maybe some used items found at car boot sales, or something you've refurbished and sold for a small profit. For many of us, this is extra income, a way to supplement our salary. However, we don't think of it as a "business," and often we don't realize that tax authorities have a completely different perspective...

Our protagonist, Mr. Krzysztof, lived in England for many years and worked a regular job, treating his extra earnings on eBay as a small supplement to his budget. He didn't know that in the UK income above £1,000 per year should be reported to HMRC. As it later turned out, lack of awareness does not exempt one from tax obligations. And although Mr. Krzysztof had no intention of cheating or hiding income, years later he received a letter that turned his life upside down. In the letter from HMRC, he saw that the tax office had charged him £82,000 in back taxes!

When do you need to declare income from online trading?

If you sell items online, there are clear rules that determine when you need to declare your income as taxable. In the UK, the regulations are quite clear:

If you sell items occasionally, for example, getting rid of a few used things from your home, you don't need to report such income. However, when trading becomes regular and generates a profit (even a small one), it may be treated as a business activity.

Anyone who earns income above £1,000 annually from trading is obliged to report this to HMRC. This is known as the "Trading Allowance", which exempts income below this amount from tax. If your online trading income does not exceed this threshold, you can rest assured and do not need to report it.

Let's analyze this with a few examples. We'll first focus on occasional sales.

If you sold your old books on eBay for £800 as a one-off, you don't need to declare this income, as it doesn't exceed the £1,000 threshold.

Another example is an old bicycle you no longer use, gathering dust in your garage. You decide to sell it on eBay for £600. Such a one-off transaction, resulting from getting rid of a used item from your personal possessions, is treated as an occasional sale and does not require reporting to HMRC, provided you don't engage in such activities regularly or continuously sell other items. In this situation, you are not exceeding the annual £1,000 sales limit, so you can rest assured.

The situation changes when you start regularly selling goods and items. Let's say you regularly buy clothes at sales and then sell them on eBay. You do this weekly throughout the year, and your total sales amount to £2,500 annually, with your profit after deducting additional costs being £2,000. In this case, your activity is treated as regular selling, as the trade is systematic and generates profit. You must declare this income to HMRC because it exceeds the £1,000 threshold.

How can HMRC monitor you?

It's worth remembering that HMRC has the right to monitor online accounts, including sales platforms like eBay, Amazon, or Etsy. If your income raises suspicions, the authority may request access to detailed data regarding sales, costs, and any other related information.

HMRC uses various technologies to monitor online activity, including algorithms that analyze financial data to detect cases of undeclared income. This allows the authority to precisely determine whether someone is conducting regular business activity.

Ignoring the tax authority and its consequences

When Mr. Krzysztof saw a letter from HMRC, he ignored it, thinking it was a mistake. Unfortunately, HMRC doesn't forget! Every letter, every contact is a serious matter. If you don't respond, the authority will assume you have something to hide. In time, HMRC sent another letter. Meanwhile, officials analyzed Mr. Krzysztof's account on eBay, his sales history, and data from the PAYE system (the British payroll system). For HMRC, this was proof that income existed and should have been declared. When Mr. Krzysztof ignored another attempt at contact, officials proceeded to "discovery assessment" which is a thorough audit aimed at calculating tax arrears based on the collected data.

What to do when you have overdue payments?

If HMRC demands payment of overdue tax from you, the first step is to make contact. Avoiding letters and ignoring correspondence only makes matters worse. Our protagonist could have taken advantage of several solutions that might have reduced his liabilities:

- Documenting expenses: If you sell items online, it's important to keep all proof of purchase, repair, travel costs, packaging, or shipping. Every documented expense can lower your taxable income.

- Agreement “Time to Pay”: This is a solution that allows you to pay off arrears in installments tailored to your financial situation. This allows you to avoid larger financial problems and carefully plan your budget.

The takeaway is clear! Don't be like Mr. Krzysztof and don't ignore your obligations, because while you might forget something, the tax office never will.
