Rookie, you say you got the 10 gs write off, i take it in the 09 tax yr which was a deduction off your income ( if not all used - carry forward ). Your fl shares now have a cost base of $ o. oo so yes if you had sold early at 3 / 4 / 5 cents or now at $ o.06 your tax would be 25 % of your low selling price. I guess waiting for a higher prices means more taxes on gains but in reality you got the shares free since your 100 % deduction.,. Rookie, as for your $ 0.05 warrant, well they expired so if you still want them they will now cost you $ 0.10 ( double the price )so keep an eye on their expiring date and compare to share trading price before exercising...Rookie..i hate to give negative news, but you can not just transfer flow through or any shares into a TFSA. Your allowed to swap / transfer $ 5,000. of either cash or shares once a yr, so thats $ 10,000 you can contribute if you haven:t yet with another $ 5,000 in 2011, THIS has to be done through your trader who must handle and record the transaction. Rookie, you can sell what you currently have in the TFSA at this point and with draw the whole amount this yr and then you would be entitled to through your trader swap back the funds from your cash/margin account plus a new 5 gs. PS; if you are transfering ?swaping shares for the monies allowed try to get keep penny shares so they can accualate tax free. ..check with Hot Muck, he has all the money. Traps7
