In Sweden, the government does the work for most normal cases. They send you a suggestion of “this is all we know about” and you just say “yeah, seems right” via SMS.

In Ireland you don’t do anything in the usual case, unless you think it’s wrong, everything is taxed at source by the employers/banks.

Both cases different if you’re a company ofc.

Brazil has started offering pre filled income tax declarations.

However, they require a digital certificate to download (probably for privacy reasons) and I don't have one so I couldn't test it.

It seems a bit naive of the government to reveal to you your income sources they know about. If you have any hidden ones you can confidently not report them and pay less taxes than you would otherwise.

It's the same in Denmark and it feels right to me. It's not like they are doing detective work (per default). If you have a concealed source of income, I'd expect them not to know about it. Of course, you'd still be breaking the law by not reporting it and it could turn up if they notice something that doesn't add up somewhere.

I assume this would still be a crime, and you'd be held responsible for lying on the past forms in discovered. The only difference is, this is optimized for making the common case easier - the case of typical income of regular, honest individuals.

Not really. Everyone is aware of what is automatically reported to the tax authorities.

Until you're selected for a random audit and quickly get charged with tax fraud.

They only know what they sent you. So an audit wouldn't turn up new information just force you to prove existing information.

Do note that it the responsibility of the employer to report who is employed, so if anything is missing, then it will generally be the company that is the one in the wrong. Especially as the company also pay employer fees for employees, so it would be a flagrant case for the tax agency anyhow.
