If you’ve been thinking about turning a hobby into extra income or picking up freelance work around the kids’ schedule, you’re not alone. More parents than ever are running small businesses from home, whether that’s selling handmade products on Etsy, offering tutoring sessions after school hours, or doing freelance design work once the little ones are in bed.
The flexibility is the big draw, but there’s a fair bit of admin that comes with it. Here’s what you’ll need to sort before your side hustle becomes a proper earner, including one insurance gap that catches most people off guard.
Register With HMRC Early
This is the bit people tend to put off, but it’s actually quick and free. If you earn more than £1,000 a year from self-employed work, you’ll need to register with HMRC for Self Assessment. You can do this online through GOV.UK, and the form itself takes around 10 to 15 minutes.
The deadline is 5 October following the end of the tax year in which you started trading. So if you began selling or freelancing in, say, September 2025, you’d need to register by 5 October 2026. Don’t leave it until the last minute, though. HMRC will send you a Unique Taxpayer Reference (UTR) by post, and that can take up to 15 working days to arrive. You’ll need your UTR to file your tax return.
Once you’re registered, you’ll file a Self Assessment return each year by 31 January and pay any income tax and National Insurance you owe.
One thing to keep an eye on: the government has announced plans to raise the Self Assessment reporting threshold from £1,000 to £3,000, expected from the 2027/28 tax year. If your side hustle brings in less than £3,000, you may not need to file a full return once that change kicks in. The £1,000 trading allowance itself won’t change, so the first £1,000 will still be tax-free.
Set Up a Workspace That Actually Works
Working from the kitchen table is fine for the first few weeks, but if your side hustle is growing, a dedicated workspace will help. It doesn’t need to be a separate room. A corner of the bedroom with a desk and some storage can be enough.
Having a set space makes it easier to switch off at the end of the day, and it helps you keep business stock or equipment out of the kids’ reach. If clients or customers will visit your home, that’s even more reason to have a defined area that looks professional. And if you do use part of your home regularly for work, you may be able to claim a proportion of your household costs (heating, electricity, broadband) as a business expense on your tax return.
The Insurance Gap Most People Miss
Here’s the one that trips people up. Your standard home insurance probably won’t cover business equipment, stock, or liability if a client visits and has an accident. Some policies include limited cover for basic office equipment, but once you’re storing stock, using specialist tools, or having clients round, you’ll almost certainly fall outside what your home policy covers.
That means if your laptop breaks, your stock gets damaged in a flood, or a tutoring client trips on your front step, you could be left paying out of pocket. It’s a common blind spot, especially for parents who start small and don’t think of their side hustle as a “real” business yet. That’s where home business insurance comes in. It will extend your existing home policy to cover business equipment, stock, and public liability. Most policies are cheaper than you’d think, especially when you’re just starting out and don’t have much kit or stock to cover.
Keep Your Business and Personal Money Separate
One of the easiest things you can do early on is open a separate bank account for your business income and expenses. It doesn’t have to be a formal business account. A basic current account in your own name will do for a sole trader. Just check your bank’s terms first, as some high street banks don’t allow business transactions on personal accounts.
This will make life much simpler when tax season comes around. You’ll have a clean record of what came in and what went out, instead of scrolling through months of Tesco shops and kids’ shoe purchases trying to find that one supplier payment. Keep receipts, save invoices, and track your mileage if you’re doing any deliveries or client visits.
Get the Admin Done, Then Get Earning
Starting a side hustle from home doesn’t require a business plan the length of a novel. For most parents, it starts with a skill, a spare hour or two, and a willingness to give it a go. But getting the boring bits sorted early, like registering with HMRC, separating your finances, and making sure your home insurance actually covers what you’re doing, will save you headaches later.
The sooner you treat it like a proper business, the sooner it’ll pay off like one.
