Britain’s rapidly growing creator economy is giving rise to a new wave of “side hustlers,” with millions of people turning online content creation into extra income. But new research suggests that many of these social media earners could face unexpected tax bills for failing to declare their income.
According to a study by Tide, the UK’s leading business management platform, the average British social media earner now makes around £1,223 a year — surpassing HMRC’s £1,000 trading allowance that permits small sums to be earned tax-free. Despite this, more than half of those generating income or receiving gifts online are unaware of the rule, leaving them vulnerable to self-assessment penalties starting at £100 and rising sharply for non-compliance.
Tide’s research found that 42% of UK adults have received either cash or gifts in return for posts on platforms such as TikTok, Instagram, X (formerly Twitter), and YouTube. While many earn only small perks or free products, a growing number — particularly among younger users — are seeing their social media presence turn into a reliable income stream.
One in five creators now earns more than £1,000 a year from their content, and over half of 18–24-year-olds report earning money online — the highest proportion of any age group. Yet only 36% of young creators have filed a tax return with HMRC, suggesting widespread confusion over what qualifies as taxable income.
Heather Cobb, UK Managing Director at Tide, warned that casual creators often fail to realise their online activities can carry tax obligations. “It’s great that TikTok and Instagram have opened new ways for people to earn,” she said. “But even if you’re paid in free products, those items have value — and that value counts toward the £1,000 allowance. If you don’t track it, you could face unexpected penalties.”
Under HMRC rules, individuals earning more than £1,000 a year from self-employment or side hustles must register for self-assessment and report their income, including the value of any gifted items. Tide estimates that total penalties across the UK could exceed £2 million annually due to late filings and “failure to notify” fines.
Cobb advised creators to keep business and personal finances separate: “Track your earnings from day one. Open a separate business account, keep receipts, and record the value of gifts. Tools like Tide Accounting can make managing tax and expenses much easier.”
For many, what begins as a hobby has evolved into a business. Megan Paul, a Tide member and founder of Gel by Megan in Warwickshire, said her nail art posts on Instagram led to brand collaborations and eventually her own training academy. “It started as a creative outlet,” she said, “but it soon became a real business. Taxes and self-assessments can be intimidating, but tools and local support make it manageable.”
The rise of Britain’s so-called “TikTok Tax” highlights how passion projects can quickly become taxable enterprises. As more people earn, gift, and collaborate online, experts say financial awareness and compliance are now essential — not only to avoid penalties but to sustain the country’s thriving digital creator economy.
