Inheritance is not subject to federal tax. Depending on the State your uncle was a resident, you may be subject to State inheritance tax.
Also, if the inheritance is distribution from a tax deferred account such as IRA or 401K or similar accounts than it may be subject to income tax.
Let me know if you have any question.

Florida does not have an inheritance tax or State income tax. So if the property you inherited is located in FL, you do not owe any inheritance tax.
As long as the inheritance is not a distribution from a tax deferred account, you do not have a income tax liability.
If your income did come from tax deferrred accounts than this would be taxed in the same manner as it would to the decedent had he taken the distribution.
If this is a regular IRA or 401K account than entire distribution will be reported as income. Note that since this is a distribution pursuant to death of the account holder the additional 10% early withdrawal penalty would not apply.
