I saw this post, but it really didn't help me.
How should I fill out my tax forms if I am only buying and holding bitcoins, not selling them?
This page appears to suggest that I only need to worry about taxes if I profit off of them when I sell them:
Buying and Selling Bitcoins Income Tax Implications Where a person trades or sells Bitcoins like a commodity (i.e., speculating on the changes in the value of Bitcoins), the resulting gain or loss may be on account of income or capital. Determining whether such a transaction is on account of income or capital can only be made following an assessment of all the facts relating to the particular taxpayer’s circumstances. Paragraphs 9 to 32 of Interpretation Bulletin IT-479R, “Transactions in securities”, provide general comments for purposes of determining whether transactions are income or capital in nature. The determination of the income tax consequences relating to the treatment of gains and losses arising from the purchase and sale of Bitcoins would be generally the same as for transaction[enter link description here]s involving other types of commodities. Example: Mr. X bought a Bitcoin on June 1, 2013 for $100. Mr. X then sold the Bitcoin on December 1, 2013 for $500. Based on his particular facts and circumstances, Mr. X determined that the gain was on account of capital. Mr. X has a capital gain since he sold a capital property for more than the total of its adjusted cost base and the outlays and expenses incurred to sell the property. Mr. X’s capital gain is $400 ($500 less $100). Mr. X will need to report $200 as a taxable capital gain (only 1/2 of the capital gain is taxable) on his 2013 Income Tax and Benefit Return.
Although I don't know how reputable that page is, so here is the official, incomprehensible source.
