There are three dates every UK side hustler needs to know: 5 October, 31 January, and 31 July. Each carries a different obligation and a different penalty for missing it. Getting them wrong costs money — sometimes significantly more than the tax owed. This guide sets out every relevant deadline for the 2025/26 and 2026/27 […]
The most common UK side hustle situation is also the one most poorly explained: you have a normal PAYE job, and you have started earning extra income on the side. How does the tax actually work when these two income sources combine? The short answer: your salary is taxed at source through PAYE as normal, […]
HMRC’s penalty system for Self Assessment has two separate tracks that run simultaneously: late filing penalties (for not submitting your return on time) and late payment penalties (for not paying the tax owed on time). Missing both triggers charges from both tracks on top of each other. The total cost can escalate quickly. This article […]
Most UK side hustlers will never need to register for VAT. The threshold — £90,000 of taxable turnover in a rolling 12-month period — puts VAT registration firmly in the territory of a full-time business rather than a supplementary income stream.Someone tutoring for £2,000 a year, reselling clothes on Vinted for £3,000, or doing occasional […]
Since April 2024, the landscape of National Insurance for self-employed people has changed fundamentally.

Claiming allowable expenses reduces your taxable profit — which directly reduces your tax bill. For a side hustler on a 20% basic rate paying 6% Class 4 NICs, every £100 of legitimate expenses claimed saves approximately £26. For a higher-rate taxpayer, the saving is approximately £46 per £100. The rule that governs all expense claims […]
The terms “side hustle” and “second job” are used interchangeably in everyday conversation. In HMRC’s view they are entirely different things, with different tax treatment, different National Insurance obligations, different registration requirements, and different implications for your employer relationship. The distinction matters most when you are deciding which structure to use for new income — […]
Whether you have already started earning from a side hustle or are about to, the same tax system applies to you: HMRC’s self-employment rules, the £1,000 trading allowance, Self Assessment registration, and — from January 2025 — platform reporting that means HMRC now receives earnings data from Etsy, Vinted, Deliveroo, Amazon, and dozens of other […]
The UK benefit system has no single income limit above which you lose everything. Different benefits operate on entirely different rules — some are means-tested with smooth tapers, others are not means-tested at all, and some cut off sharply at a specific threshold. Understanding which rule applies to which benefit is the only way to […]
