The gift to your son of $15,000 is not reported on your tax return. Nor do you have to file a Form 709 for the gift given since it was not over $15,000.
If you receive Social Security Disability benefits you will receive a Form SSA-1099 in January. Also in January you will receive a form 1099-R for the withdrawal from the IRA. The taxable amount of the withdrawal is entered on your tax return as ordinary income. Both the Form SSA-1099 and the Form 1099-R are entered on your tax return.
Up to 85% of Social Security Retirement/Disability/Survivors benefits becomes taxable when all your other income plus 1/2 your social security reaches:
- Married Filing Jointly - $32,000
- Single or Head of Household - $25,000
- Married Filing Separately - 0
If your taxable income is greater than the standard deduction for your filing status then you will have a tax liability and if you did not have any tax payment or the tax payments were less than your tax liability you will have taxes owed.
