| Linda,
I suspect that when you come down to filing your tax return, most of your social security income would be exempt from taxation. Furthermore, you would also enjoy the personal exemption and standard deduction that may effectively eliminate any taxable income.
So, there really may not be any need to deduct your premiums as the standard deduction would be substantially higher than itemization deductions in your case.
For your information, the standard deductions for 2007 are $7,500 for a Single, and $15,000 for Married Filing Jointly filiers. |
