It depends on your basis in the inherited property.
You will only need to pay capital gains taxes on the sale of your proportional share of the inherited property if you sold the property for a gain. So if you and your brother inherited the house 50/50, then your basis in the inherited property will be 50% of the FMV of the property at time of death. Depending on how much your brother paid to buy out your share will determine your gain or loss on the sale. Just be aware that since you are selling to a relative, the IRS may need proof of an arm's-length transaction if you sell your share at a loss and you will only report this capital loss if the property was not considered personal use property (such as an inherited rental property) between the date of inheritance and the date of sale.
Also, if you have a capital gain on the sale and the property is located in a state of which you are not a resident, you may have to file a nonresident state return in that other state regarding any capital gain.
