Is a 'side hustle' the same as a part-time job?

Not exactly. A part-time job is often a formal, scheduled employment arrangement. A side hustle is typically more informal, entrepreneurial, and self-directed, though it can overlap.

Do I need to declare income from a side hustle?

Yes, in both the UK and US, income from a side hustle must be declared to tax authorities (HMRC or IRS). It's considered taxable income.

What's the difference between a 'hobby' and a 'side hustle'?

The key difference is intent to generate income. A hobby is primarily for enjoyment; a side hustle is pursued with the aim of earning money, even if it's also enjoyable.

Can 'side hustle' be used as a verb?

Yes, informally. E.g., 'She side hustles as a copywriter.' The verb form 'side-hustling' (often hyphenated) is increasingly common.
