OnlyFans Tax Deadline 2026: Have You Left It Too Late?

Your Questions Answered

OnlyFans creators have a tax deadline approaching – and if you earned more than £1,000 during the 2025/26 tax year, 5 October 2026 could be a date you really don't want to overlook.

If you've been earning money from OnlyFans, there's a good chance you've already asked yourself the usual questions.

“Do I need to pay tax?”

“How much will I owe?”

“Can HMRC see my earnings?”

But there's another question that is particularly important right now:

“Do I need to register for Self Assessment – and have I left it too late?”

The answer could depend on your income during the 2025/26 tax year.

5 FAQ's We Hear (A Lot!)

1) "So, what's special about 5th October?"

For anyone who needs to register for Self Assessment for the first time for the 2025/26 tax year, 5 October 2026 is the registration deadline. That date is fast approaching. And it's important to understand what it actually means. 5 October isn't the date you have to pay your tax. It isn't the date your tax return has to be submitted. It's the date by which you generally need to tell HMRC that you need to complete a Self Assessment tax return for the previous tax year. For OnlyFans creators who have crossed the relevant income threshold, that makes October an important month to get organised.

2) “But I don't have to submit my tax return until January, do I?”

Yes – and this is where the dates can become confusing. For the 2025/26 tax year, the tax year ended on 5 April 2026. If you need to register for Self Assessment for the first time, the registration deadline is 5 October 2026. The deadline for filing your online Self Assessment tax return and paying the tax you owe is generally 31 January 2027. So there are two completely different deadlines to remember:

5 October 2026 – register for Self Assessment if required.

31 January 2027 – file your online tax return and pay the tax due.

Missing one doesn't necessarily mean you've missed the other. But if you're a creator who should have registered and you're approaching October without having done anything, now is the time to act.

3) “I've only just realised I might need to register. What should I do?”

First: don't panic.

Second: don't ignore it.

If you think your OnlyFans income means you need to register for Self Assessment, work out your position as soon as possible. Look at your income for the 2025/26 tax year and establish whether you have exceeded the relevant threshold. If you do need to register, you can do this through HMRC. But this is also where professional advice can save you a considerable amount of stress. Creators often have more complicated tax affairs than they initially realise – particularly if OnlyFans income is combined with employment, other creator platforms or other self-employed income. Getting the registration right is the first step. Making sure the eventual tax return is correct is the next.

4) “What happens if I miss 5 October?”

This is probably the question that will worry creators most. Missing a tax registration deadline doesn't mean you should simply give up or wait until January. If you realise you've missed the deadline, the sensible thing is to deal with it as soon as possible. Don't wait until the tax return deadline simply because you haven't received a reminder from HMRC. And don't assume that because HMRC hasn't contacted you, you're not required to register. Your tax obligations don't depend on whether HMRC contact you or not.

5)“I only started my OnlyFans after 5 April 2026 – does the 5 October deadline apply to me?”

Not necessarily. This is an important distinction because the 5 October 2026 registration deadline relates to the 2025/26 tax year, which ended on 5 April 2026. So, if you only started earning from OnlyFans after 5 April 2026, your income falls into the 2026/27 tax year instead.

That doesn't mean you can forget about tax – it simply means you're looking at a different tax year and a different set of deadlines. For example, if you started your OnlyFans account in June 2026, the income you earn from then onwards belongs to the 2026/27 tax year.

You'll need to keep appropriate records and establish whether you need to register for Self Assessment based on your income and circumstances. The important thing is not to assume that the 5 October 2026 deadline automatically applies just because you're earning money from OnlyFans now.

If you're unsure which tax year your income falls into, or whether you need to register, it's worth getting advice now rather than waiting until you're approaching your eventual filing deadline.

Final Thoughts

Tax deadlines can feel confusing, particularly when your OnlyFans income is something you've started alongside your usual job or other commitments. The good news is that getting organised now really can make the whole process much easier.

If you think you may need to register for Self Assessment for the 2025/26 tax year, 5 October 2026 is an important date to have on your radar. And if you're still unsure whether the deadline applies to you, there's no need to work it out alone.

At OnlyTax, we understand that every creator's circumstances are different. Whether you're new to OnlyFans, earning alongside a PAYE job, or simply want reassurance that you're meeting your tax obligations, we're here to make the process straightforward and stress-free.
