HI For 2015 i plan on having total taxable income of around $30,000

I have (from a Trust distribution ) a rather large amount of capital gains, over $50,000. I received this distribution in January 2015.

I thought i was going to have to start making IRS Quarterly estimated payments, especially for a 15% capital gains tax rate for the sizable amount (over $50,000 ) of capital gains ( Land Sale ) on a Trust Distribution.

If i keep my 2015 ordinary taxable income below $36,900 ( the top of the 15% income tax bracket ) will i then have a long-term capital gains tax rate of 0% ?
