A while back, I started the thread on fiat-to-crypto and it gathered some good inputs, notably bitcoinsuisse as same jurisdiction on-ramp for all who wish to explore.

Now that I hold multiple currencies (thank you, ShapeShift), few questions on the tax side:
1) how do you list them in your tax return?
2) will profits be subject to 35% tax on withdrawal?
3) what is the smart way to "off-ramp" to fiat when that time comes? At this point, I am planning to hodl until such smart ways become apparent.

Thank you!

1) list them as you would a stock or bank account.
2) No income paid so no withholding tax
3) Market timing is impossible, 1,000 may come before 10,000 rather than after is the issue at hand. Bubbles burst far faster then they went up, you may not have the time to get out & stop losses may never execute if there are no buyers at the price you set.

For 2) above, would you not regard the August 1st "gifting" of 1 Bitcoin cash for each Bitcoin (where registered) as income or rather capital gain/appreciation?

It's a split or reorganisation IMHO, the Bitcoin value dropped as a result.

whereas the aggregate result BTC+BCH was higher

It's not criminal to not declare. As long as taxes to be paid don't exceed 300k per year, but wealth tax rate is pretty low

Ok, yes, in the future when you declare a yacht or a private jet that you'd buy off your bitcoin savings, this might raise an eyebrow or two at the tax office and force you to backdate a declaration. Not big deal, you just pay missing taxes plus a little fine, cost of business so to say, and it's all O.K. again

Swiss routinely don't declare things like rental deposits and noone gives a damn

Not at the time of the split, but afterwards.

Bought some crypto a couple of years ago and wanted to cash out a bit in this round. I have a question regarding the tax reporting and end up with this thread.

Q: Do I need to list all my crypto assets in my tax report, or only the ones I sell? The market is so volatile, thus reporting the value of unsold tokens makes little sense to me. Any experience / suggestions here?

Thanks!
