I asked my accountant recently regarding capital gains tax: here was his response.
Capital gains held under 1 year are taxed at ordinary tax rates and are not subject to preferential tax treatment. The rates vary between 10% - 39.6%. You would most likely fall between 25% - 33% tax rate.
Capital gains held for longer than 1 year will be taxed at 15% which is the best outcome. If you and your spouse make less than $37,950 in 2017, the Long Term capital gains tax rate will be 0%.
