HMRC Handed Ukraine 17,800 OnlyFans Accounts. The Court Record Is a Warning for UK Creators

Britain’s tax authority now passes creator earnings files to foreign tax offices automatically. Ukraine has already fined, collected, and lost in court. Every step of what happens next is documented, and it applies to UK side earners too.

In September 2026, Ukraine’s State Tax Service confirmed in writing what it had been building for two years: a complete dossier on every Ukrainian who has ever earned money on OnlyFans. 17,800 accounts, with names, payment histories and earnings, supplied by Britain’s own tax authority. The same statement said that only 13 per cent of Ukrainian OnlyFans models had ever paid tax on that income (Komersant, reporting the tax service’s reply to a press query, 21 September 2026).

The dossier arrived through the ordinary machinery of international tax cooperation, with HMRC as the sending office. Since 2024, HMRC has been feeding OnlyFans earnings data to Kyiv (The Telegraph, 25 July 2026). The result is now playing out in Ukrainian courtrooms: 94 lawsuits between creators and the tax service, dozens of fines voided, hundreds of thousands of hryvnias collected anyway, and one model who erased a bill of nearly half a million pounds with nothing but her bank statements.

Those court files are worth reading in Britain, because the pipeline that produced them runs through London and points both ways. The company that reports every OnlyFans creator to HMRC, Fenix International, is a UK firm with an office on Cheapside. The same dataset that reached Kyiv sits on HMRC’s own systems for British creators, and it arrives every January. Ukraine’s cases show what that data does once a tax authority decides to act on it.

How the file leaves London

From 1 January 2024, the UK’s digital platform reporting rules require platforms to collect each seller’s name, address, date of birth and tax identification number, and to send the year’s earnings to HMRC by the following 31 January (GOV.UK guidance). OnlyFans’ UK parent has reported under those rules since the first cycle, with 2024 data filed by January 2025. HMRC’s guidance is explicit about what happens next: if a seller lives in another country that follows the same rules, HMRC shares the seller’s information with that country’s tax authority. For Ukrainian creators, the receiving authority is the State Tax Service in Kyiv, and the transfers began in 2024.1. Creator earnsSubscriptions, tips andcustoms flow throughFenix International (UK)2.

Because OnlyFans’ parent company is British, every creator worldwide reports to London first. HMRC keeps UK residents’ records and passes foreign residents’ records on automatically.

Ukraine’s tax service has said what it did with the file. It began contacting creators and asking about their tax obligations, work coordinated with the country’s Economic Security Bureau. Creators have since paid more than £1.8m in back tax for 2020 to 2023, and the authorities estimate that Ukrainians earned over £100m on OnlyFans between 2020 and 2022. In 2023 alone, 7,900 Ukrainian creators earned more than $131m, according to the tax data the platform’s UK parent handed over (News18, 28 September 2026). Seventeen thousand eight hundred accounts, and one in eight paying tax.

Why the file overstates what creators keep

GOV.UK says platforms must report the total a seller earned in the year, less any fees, commission or taxes the platform itself deducted. For an OnlyFans creator that means the figure after OnlyFans’ standard 20 per cent cut, but before anyone else takes a share. Many creators work through agencies that run their marketing, messaging and schedules, and those agencies take most of what remains. Lesia Mykhalenko, a lawyer representing several of the models, told The Telegraph that many of her clients took home just 15 to 20 per cent of the revenue flowing through their accounts, and that the taxes now being demanded exceed the income they received.Where £100 of fan spending goes, with an agency in the middle£25£50£75£100Fan pays £100OnlyFans commission–£20Reported to HMRC (and passed abroad): £80Agency cut (up to 85%)–£68Creator keeps £12Tax is assessed on the amber £80, not the green £12. Agency figures are the upper bound reported by lawyers; some creators pay less.Sources: GOV.UK reporting guidance; The Telegraph, quotes from lawyer Lesia Mykhalenko.The reporting gap. The exchanged figure nets off the platform’s commission but ignores agency cuts, chargebacks and expenses. A creator who keeps £12 of every £100 can be taxed on £80.

That mismatch is why some Ukrainian bills have run ahead of the money the creator ever saw.

What the court files show

Opendatabot, the Ukrainian open-data project, searched the country’s unified court register and found 94 cases in which OnlyFans creators challenged the tax service, with at least 27 rulings that fully or partly overturned the fines (Opendatabot, 3 April 2026). In 92 per cent of successful cases, courts sided with the creator because of procedural failures by the tax service, most often notices sent to outdated addresses while audits went ahead anyway (New Voice of Ukraine, 3 April 2026). And courts have consistently treated letters from British tax authorities about Fenix payments as grounds to open an audit, leaving the income itself to be proved separately. Without bank statements, contracts or other primary documents, additional assessments fall.Creators’ score so far: at least 27 of 94 cases won or partly wonCreator won or partly won (at least 27)Lost, ongoing, or unresolved (67 of 94)13 of the wins came in 2026 alone;February set a record with five.Regional spread of wins:Odesa 8, Dnipropetrovsk 5, Kyiv,Cherkasy, Ivano-Frankivsk amongthe rest.

In Kyiv, a creator faced more than 3m hryvnias (roughly $68,500) in assessments built on an alleged income of nearly $400,000. She produced her own bank statements, which did not confirm those amounts, and the court voided the bill. The tax service had no primary documents at all in Cherkasy, and more than 1.3m hryvnias in taxes and penalties collapsed with them. A simple address error did for the Odesa case, where a penalty over 500,000 hryvnias fell because the audit notice never reached its target. The Telegraph separately reports one model who overturned a fine of nearly £500,000 the same way, with bank statements.

In Ivano-Frankivsk, the tax service cited data supposedly shared by HMRC about a local model. She contacted the British tax authority directly and received an official reply: no information about her had ever been transmitted. The Ukrainian authorities had relied on data that did not exist, and the court cancelled every assessment.Six rulings that define the pattern

Case	What the tax authority claimed	Outcome	Why
Kyiv	>3m UAH (about $68,500) in tax on an alleged income of nearly $400,000	Voided	Creator’s bank statements contradicted the figures
Ivano-Frankivsk	Assessment based on “HMRC-shared data”	Voided	HMRC confirmed no data on her was ever sent; the evidence did not exist
Cherkasy	>1.3m UAH in taxes and penalties	Voided	Complete absence of primary documents
Odesa	>500k UAH penalty	Voided	Notice sent to wrong address; audit ruled unlawful
Supreme Court, case 240/22077/25, 17 Jun 2026	About 400k UAH in extra assessments	Quashed	Platform data is indicative only; it opens an audit, it does not prove income
Kirovohrad oblast, upheld 29 Jul 2026	$14,300 of Fenix income; income tax and military levy assessments	Upheld	Appeal courts left the assessments in place; more than 570k UAH collected

In the Kirovohrad case, the courts upheld assessments built on $14,300 of reported Fenix income, and more than 570,000 hryvnias (about £10,400) was collected. The exchanged data is a starting point, and everything depends on what the person on the other side can put on paper.

The Supreme Court of Ukraine settled the legal principle in June 2026, quashing about 400,000 hryvnias in assessments and ruling that information from a foreign platform is indicative data requiring corroboration (Antikor, 30 June 2026).

The enforcement pressure is rewriting Ukraine’s law

Making and distributing pornography remains a criminal offence in Ukraine, carrying up to seven years in prison, which is why many creators avoided any contact with the tax office. After HMRC’s data arrived, some models were threatened with prosecution under those anti-pornography laws; the cases were dropped after a public backlash, according to Mykhalenko.

The most prominent case belongs to Svitlana Dvornikova, a creator with around a million subscribers, who says the authorities demanded $900,000 in tax on her 2024 income, raided her home, seized devices and brought criminal charges. Her petition gathered the 25,000 signatures required to force a presidential response, and her argument is now the argument of the reformers: if creators can work legally, they will pay taxes openly. “If we end up legalizing this, it means we can work calmly, make money properly and pay taxes to the state,” she said; her criminal case is paused while the bill proceeds (News18, 28 September 2026).

A decriminalisation bill, number 15294, passed its first reading on 14 July 2026 by 231 votes to eight, the third attempt after two earlier bills failed, including one in May that fell 207 votes short of the 226 needed (Babel, 14 July 2026; UNN, 28 May 2026). The finance committee’s chairman puts the tax upside at almost a billion hryvnias a year, and the tax service already collects from the grey economy it is supposed to be suppressing: OnlyFans-related payments into Ukraine’s budget reached $1.6m in 2025, up 18 per cent on 2024, with no legalisation in place.

How this ends at home

Back in the UK, the same pipeline points at British creators. Fenix International reports UK-resident creators’ data straight to HMRC under the same rules that produced the Ukrainian file: name, address, tax ID, and the year’s earnings net of the platform’s fees, broken down by quarter. HMRC has already received the files for calendar years 2024 and 2025; the 2026 file arrives by 31 January 2027. That is also the month the 2026–27 self-assessment deadline falls, which means HMRC will be holding both the creator’s return and the platform’s version of their income in the same system, side by side. HMRC has spent years urging side earners into self-assessment, and its own research says one in ten people operates in the hidden economy, most of them unaware they should be registered.The numbers a UK platform earner is dealing with right now

Every successful defence in Ukraine rested on documents the creator produced. Not tax advice: a summary of what held up in court and what HMRC’s own rules require.

In the UK, creating adult content is legal, so the exposure for identified creators stops at tax. That removes the single biggest reason Ukrainian creators stayed silent while interest accrued. The arithmetic is otherwise identical. The platform’s number arrives first, it overstates take-home pay for anyone with an agency, and the burden of correcting it falls on the person with the smaller legal budget.

What stays true

A London company now files every creator’s earnings with a government agency each January, and those files cross borders automatically. The exchanged number is a gross figure that ignores the agency economy, which is why the first wave of bills overshot real income and courts have been busy unwinding them. And the outcomes already follow a clear pattern, decided by the documents the creator could produce.

For UK creators earning from OnlyFans, Fansly or any reporting platform, the dates are fixed in statute: the 2026 earnings file lands at HMRC on 31 January 2027.

Conversions are approximate, at mid-2026 rates of about 41.5 hryvnias to the dollar and 55 to the pound. The £500,000 reversed bill is as reported by The Telegraph; Ukrainian sources’ largest voided assessments are stated in hryvnias and may reflect different measures. Account counts differ by period: 17,800 accounts in the Ukrainian dossier versus 7,900 creators with 2023 earnings. This piece is reporting and analysis. It is not tax advice.
