Secret bank account

Most likely a civil offence, but depending how you do it, it could be criminal.

I have better rates!

Assuming you meet the necessary MLA requirements, opening an account should not be a problem.

But keeping it secret is another matter:

- First of all you need to have a very good memory and think several steps a head all the time or at some point you'll slip

- Second you need to ensure that no documents are send to your residence. Banks do offer this service for a fee

- You should declare it for tax purposes and if you get caught you'll need to deal with the consequences. How if it is a join declaration, the your spouse will become involved.

- Then you need to think about how will fund it and spend it without attracting attention of your spouse

If it is a couple of Ks it might be as well to stuff it in a biscuit box and hide it somewhere.

Wait, let me ask the tax office in your gemeinde and get back to you. I'm sure they have an opinion.

With current interest rates cash in your mattress is the best option.

Yeah very true I always prefer a physical card but those who prefer Apple Pay and the like can do without one.
