> They give you a space that you input it in, if there's something missing

And someone working minimum wage with no overseas dividend income must manually read every space for these “missing” line items?

Seems like you’re wasting the minimum wage worker’s time.

Here in the UK, minimum wage workers do not have to do a self-assessment. Only certain circumstances require you to return a self-assessment, some of those circumstances include earning over 150k or having income beyond your usual PAYE income (e.g. dividends etc). A majority of workers don't need to deal with any tax returns or whatnot. At the end of the year they simply either get a rebate or asked to pay what if they've underpaid. Some of those who underpaid don't even need to worry as their tax code is adjusted to include what they owe in their next tax year allowing the payment to be spread over a year.
