If we're only talking about income, your only option is contracting (or maybe starting a successful business...). If you are willing to work on your expenses, then a lot of other avenues open up to you; you can make significant savings by moving to a country with lower taxes and/or cost of living (for example Romania). Keep in mind that coming from Austria, you may experience some culture shock.

Here are some quick back of the napkin calculations:

Austria

Gross: 80K

Net: 49K

After rent: 41K

Romania

Gross: 80K

Net: ~71K*

After rent: 66K

* Micro-company at 1-3% tax on revenue, 5% dividend tax, ~€2000/year social contributions (once you cross a certain limit), €500/year accountant. I am not a lawyer or accountant so please check with one before making any decisions ;)
