For example, say that your traditional IRA has a cost basis of $30,000 and is worth $100,000 when you take a $10,000 withdrawal. That means 30 percent of the withdrawal comes out of your cost basis and is tax-free; 70 percent comes from the remainder of the account and is taxable.
The cost basis methods approved by the IRS include: 1  Average Cost. Using the average cost, cost basis is calculated based on the average price paid for all shares held, regardless of holding period. 2  First In, First Out (FIFO) Using FIFO, cost basis is calculated using the specific amount paid for shares. 3  Specific Shares.
