I Sell Online. What Do I Need to Know About Making Tax Digital?
If you sell products through your own website, run a WordPress store, or use marketplace platforms like Etsy or eBay, there’s a good chance you’ll be affected by changes in how tax is reported in the UK. Making Tax Digital (MTD) is the government’s way of bringing tax into the 21st century — making things simpler and less of a chore. It means keeping your records online and sending updates to HMRC using software that’s set up for it, cutting out paperwork and helping avoid slip-ups. The idea is to make tax easier to manage, more accurate, and less time-consuming for people running their own businesses. Whether you’re new to online selling or perhaps you just haven’t had time to look into MTD yet, this guide will hopefully give you a good overview of what to expect.

What is Making Tax Digital (MTD)? Making Tax Digital (MTD) is the government’s way of bringing the UK’s tax system into the digital age. The main idea is to make tax simpler, quicker, and a lot less stressful — so no more digging through shoeboxes full of receipts or panicking at the last minute. With MTD, you’ll be expected to keep your records digitally and send updates to HMRC more regularly, rather than just once a year. This is already a must for some businesses, and more people will be joining in soon. So, what does this mean in practice? ✓ Digital Record-Keeping: Businesses and individuals must keep their tax records digitally (for example, using accounting software). ✓ Regular Updates: Tax data is submitted to HMRC more frequently, typically quarterly, rather than once a year. ✓ Use of Approved Software: Submissions must be made using HMRC-recognised software or bridging tools. If you sell online and take care of your own taxes, MTD is definitely something to have on your radar. But don’t worry — it’s really not as scary as it sounds! 2. Why was Making Tax Digital introduced? HMRC’s main goal is to cut down errors and make tax simpler for everyone. Many people either under-report or overpay because of missed paperwork, forgotten income, or last-minute guesses. MTD aims to reduce this by using digital tools to keep everything accurate. Making Tax Digital isn’t new — it was first introduced back in 2015, with the government setting out their plans to get everyone keeping tax records online. Since then, it’s been rolled out in stages, and now more and more businesses and individuals need to get on board. If you’ve just started an online business or are new to managing your own taxes, it’s definitely something you’ll want to know about. For online sellers juggling orders, fees, and stock, this clearer picture of your finances throughout the year can be a real help. Moving everything online, HMRC hopes to save you time, stress, and paperwork. Here’s the catch — many sole traders aren’t prepared yet. Research from IRIS Software found nearly half of UK sole traders aren’t ready for the changes, with 31% saying they’d never even heard of MTD. Around 45% risk failing to comply with the new rules, which could lead to penalties. There’s also a communication gap between sole traders and HMRC. Around 74% say they don’t get enough guidance, and many are waiting on official info before moving forward. Interestingly, younger sole traders tend to be more prepared — 37% of those aged 25-34 feel ready, compared to just 10% of those aged 45-54. 3. Who needs to follow the rules? MTD is becoming a must for more and more people. It’s already mandatory for all VAT-registered businesses, and from April 2026, it will be required for self-employed people (like website owners working as sole traders) earning over £50,000. The threshold drops to £30,000 in April 2027, so even if you don’t have to follow the rules just yet, it’s worth preparing now—because chances are, you’ll need to use MTD sooner rather than later. Right now, VAT-registered businesses with taxable turnover over £85,000 have had to follow MTD rules since April 2019, and smaller VAT-registered businesses joined in from April 2022. MTD isn’t just for sole traders—it covers a range of business types depending on their tax affairs: ✓ Sole traders and self-employed people who earn over certain thresholds will need to comply with MTD for Income Tax (from April 2026 for most). ✓ VAT-registered businesses of any size, including companies, partnerships, and sole traders — they’re epected to use it for VAT. ✓ Landlords with rental income over certain levels also fall under MTD rules for Income Tax. Limited companies and other incorporated businesses will face MTD requirements as it expands, especially for Corporation Tax in the future. If you’re self-employed and earning over £50,000 from April 2026, you’ll need to use MTD for Income Tax. Those earning between £30,000 and £50,000 will be included from April 2027. If you sell online and report your income through Self Assessment, it’s worth checking where you stand. You might not need to do anything yet, but it’s smart to be prepared!
