Nope. My CPA in the USA said it was likely to be a taxable event if I sold any. She said leave it alone for 1 year and 1 day for
20% capital gains tax, here in the states, (rather than 40% if less time) and she 'assumes' the IRS will just see it as a stock split.
Correct. This is also why I ran my business as a LIFO based accounting system: When I need money for parts or power or taxes I sell bitcoins at a rate that is close to what I received, thus minimal short term CG taxes. Since I receive payments in bitcoin I make sure to pay income taxes on the money received at the value of bitcoin at the time the work was agreed to (because the price might change by the time the work is completed and I receive payment, but I consider that to be float, not increased revenue. Need to check with a CPA or the IRS on that, but I do the best I can do).
Thus the stuff I made over the years is free and clear of anything but capital gains taxes, which would be paid if I sold deep enough into my account.
And since I have never purchased a bitpenny, if bitcoin went tits up I would really not lose anything in the real world other than the value of my labor.
A really interesting side-effect happens when I buy other services for bitcoin, tax analysis on that is a bitch on wheels. Have to convert to cash virtually on the ledger, then convert back to goods and services. Sucks.
