Correct. You only need to file a tax return with HMRC if you're registered as self-employed.
31 January at 23:59 is the annual party. When 90% of people do it lol.
Most people just fill out the basic form. But I guess if you're an entrepreneur who makes money from migrant hotels and trafficking pedos and sex offenders (is that your thing?), you might have to tick a few more boxes tbf.
And anyway (as far as I know) it's the same for the whole of the UK; not just England. We're in 2025, not the 16th century.
