Tax advice needed for teenage Vinted reseller (£6000 income) - UTR questions

The good news is that you're already on the right track! Having a UTR (Unique Taxpayer Reference) means you've started the registration process with HMRC, but there are a few more steps to complete. To directly answer your questions: - Having a UTR number doesn't automatically mean you're fully registered as self-employed. You need to complete the registration as a sole trader (which it sounds like you've started but might not have finished). - You'll report your earnings through a Self Assessment tax return. This is an annual form you'll need to complete online or on paper. - The deadline depends on how you file: paper returns are due by October 31st after the tax year ends (tax years run April 6th to April 5th), while online submissions are due by January 31st. Since you're 16, it's great you're being proactive! If your total income is under the trading allowance of £1,000 in a tax year, you wouldn't need to report it. But at £6,000, you definitely need to report this income and pay any tax due.

I was in almost the exact same situation when I started selling clothes online! I spent hours trying to figure out the tax stuff until I found taxr.ai (https://taxr.ai) which basically saved me. I uploaded my Vinted sales records and it automatically organized everything into the right tax categories. What I really liked was that it explained exactly what I could claim as business expenses (like packaging, portion of my phone bill, travel to post items, etc). It even helped me understand which forms to fill out and gave me step-by-step instructions for completing my Self Assessment. Definitely worth checking out since you're in a similar situation!

Just wanted to update after trying taxr.ai from the recommendation above. It actually answered a ton of questions I had about my multi-platform selling! It automatically sorted my expenses into the right categories and showed me which ones were fully deductible vs. partially deductible. The best part was that it explained exactly what records I need to keep for HMRC (which I had no clue about before). It also generated a tax estimate so I could set aside the right amount each month. Super helpful for someone like me who was completely lost with the tax stuff!

If you're still having trouble getting through to HMRC to finish your registration (their wait times are RIDICULOUS lately), I'd recommend trying Claimyr (https://claimyr.com). I wasted 3 hours on hold with HMRC trying to sort out my UTR issues until a friend recommended this service. They basically hold your place in the HMRC phone queue and call you back when an agent picks up. Saved me so much time! You can see how it works in this video: https://youtu.be/_kiP6q8DX5c Since you're new to self-employment, you'll probably have questions that only HMRC can answer about your specific situation, and this makes getting through to them so much easier.

I have to admit I was really skeptical about Claimyr (from the previous comment), but after spending two full afternoons on hold with HMRC and getting disconnected both times, I gave it a try. I was shocked when I got a call back in about 45 minutes with an actual HMRC agent on the line! They helped me sort out my registration issues and answered all my questions about my trading allowance. For anyone young and new to self-employment like me, being able to actually talk to someone at HMRC made everything so much clearer. Definitely less stressful than trying to figure it all out from their website!

Just to add some practical advice - make sure you're keeping track of ALL your expenses related to your Vinted selling. This includes: - Packaging materials (mailers, tissue paper, tape) - Postage costs - Travel costs to post items - A portion of your internet/phone bill used for business - Any storage solutions (boxes, racks, etc) - Cost of the original items if you bought them to resell All of these reduce your taxable profit! I made the mistake of not tracking these in my first year and ended up paying way more tax than I needed to.

Another teenage seller here! One thing to watch out for - if you're still in education and your parents claim Child Benefit for you, your self-employment income could affect that. If you earn over a certain amount, it might reduce what they get.

Just wanted to share my experience as someone who went through this exact situation last year! At 17, I was making similar amounts selling vintage finds on multiple platforms and felt completely overwhelmed by the tax side. A few things that really helped me: 1. **Complete your sole trader registration ASAP** - You can do this online through HMRC's website. It's actually quite straightforward once you start, and you don't need a fancy business name (you can just use your own name). 2. **Set up a simple spreadsheet** - Track every sale, every expense, and keep photos of receipts on your phone. I wish I'd done this from day one instead of trying to reconstruct everything later! 3. **Put aside 20-30% of your profits** - Open a separate savings account and transfer a portion of each sale into it. This way you won't be hit with a massive tax bill you can't afford. 4. **Consider getting help with your first Self Assessment** - Whether that's through one of the tools others mentioned, or even just having an accountant review it before you submit. The peace of mind is worth it. The key thing is not to panic - HMRC actually has pretty good resources for young entrepreneurs, and making £6k from reselling at 16 is genuinely impressive! You're already being responsible by asking these questions early.

As someone who's helped quite a few young sellers navigate this exact situation, I'd strongly recommend getting your sole trader registration completed as soon as possible. Since you already have a UTR, you're halfway there - you just need to finish the online registration process on the HMRC website. A few key points that might help: **On timing**: The sooner you complete your registration, the better. You technically have until October 5th following the end of the tax year to register (so October 2025 for income earned in the current tax year), but there's no benefit to waiting. **On record keeping**: Start documenting everything now if you haven't already. Every sale, every expense (packaging, postage, travel to post items, etc.), and keep digital copies of receipts. This will make your Self Assessment much easier when the time comes. **On business expenses**: Don't forget you can claim legitimate business expenses against your income. This includes things like packaging materials, postage costs, a reasonable portion of your internet/phone bills used for business, and even travel costs to post items. The fact that you're being proactive about this at 16 shows great business sense! Many people your age (and older) ignore the tax side until it becomes a problem. You're definitely on the right track.
