Your post is somewhat difficult to decipher since you wrote "re-setting this capital gain at zero".
Obviously, you cannot "reset" capital gains; you can either recognize them through sales transactions and report them on your income tax return or offset them with capital losses.
Regardless, you might want to use TaxCaster (link below) to get a rough idea of your tax liability on $227,000 in capital gains.
