Earlier quoted context omitted.
The deadweight loss of taxation is much lower for a land tax than an income tax. The deadweight loss is the economic resources allocated to complying with the tax. The armies of tax lawyers would be able to perform other economically productive activities if they weren't pouring over the tax code. Pigovian taxation is even better. Taxing gas is a great example.

As an Australian who moved to Sweden, I was amazed at how efficient the Swedish income tax process was. The government already knew everything they needed to calculate your return, and gave it pre-filled. There were not endless exemptions. Nobody at my work used an accountant, most approved their tax with a few clicks and were done. So much more efficient than in Australia!
You could choose to use them (for example, the self education one) and get SEK5000-SEK10000 (~€500-€1000) BUT then you would have to fill out a tax return.
That is just one exemption. Another one relevant for our field is working from home. Similar amount.
In order to claim those, though, you will need to file a tax return. If you do not consider that money to be worth the time, then not filing one is a good choice.
The Australian system - which could definitely be improved by at least pre-filling things - forces you to actively choose to leave the money behind. The default in the UK, Europe and the Nordic countries is that the money is kept by the taxaxtion office.
Defaults are powerful. And they thank you for entrusting them with your extra SEK that you do not want to claim.
