Capital gains are basically what the IRS would like to call as your bulk profits, when you engage in a transaction in context of capital asset. Whenever you sell these capital assets, the money you get as profit is termed as a capital gain. These are taxed, and in certain cases quite heavily. Things like real estate, stocks, bonds, mutual funds, etc are all deemed as capital assets that would be filed under capital gains, upon your receiving any profits based on their transactions.
If you have inherited an estate or fortune, they might be considered as capital gains and taxed accordingly. However, there are many clauses and rules that fall under the income tax law so ensure that you have them at your fingertips, before you are assaulted by the IRS for incorrect filing. Of course, before deciding to venture into bonds, stocks, and options, make sure you know how much money you actually stand to make, and how much you owe to Uncle Sam, as taxes.
In a sense, it pays off if you are aware of the federal tax deductions that you can take advantage of, before you actually file your returns. In case of IRS capital gains, you need to be aware of what kinds of assets are actually termed as capital gains. Not all profitable transactions can be placed under capital gains, so before you decide to file them under capital assets, double check the clauses of the income tax regulations. You not only save yourself a certain amount of money, but money is also diverted in a profitable manner.
