Not in most cases. If the IRA purchases of property and then sell it to gain the benefits stay within the IRA. If you have a traditional IRA, the gains are exempt delayed. If you have a Roth IRA, the gains are exempt from tax.
Note, you alter that result if you use leverage through borrowing. If you borrow one third of the money then one third of the profits are taxed.
