Approximately how much is the capital gains tax on $100,000 if I withdraw it from my mutual fund in 2017 to buy a home?

[PaulaM]

The tax rate will depend on your tax bracket that you are currently in and whether the gains will be short-term or long-term.

If you're in the 10% or 15% tax bracket, you won't owe any capital gains taxes on securities you've held long-term, including mutual fund shares. Long term-capital gain rates range from 0%—20% and may also be subject to the 3.8% Medicare Surtax above a certain income threshold.
