Norway is technically not in the EU, just the EEA (European Economic Access) zone. But we do it the same way. Our tax authorities get all information they need from employers, banks, stock brokers, etc. Each citizen then get a tax settlement report and can submit a pre-filled tax statement online. You make any adjustments to taxable income or tax deductions that might be missing, and then you are done. Pretty simple.
