* Iowa taxpayers who received Social Security
benefits in 2008 and claimed bonus depreciation on their federal returns
for property subject to the bonus depreciation calculation may have
to recompute their taxable benefits on the worksheet.
Those who need to recompute the taxable Social Security benefits should add the bonus depreciation adjustment from line 5 of Schedule IA 4562A to the other amounts shown on line 3 of the Social Security worksheet from the federal return and the RRB 1099. The rest of the form is then completed with the amounts normally used to complete the worksheet from the federal 1040 or 1040A.
Include the following incomes or adjustments to income on line 3 if applicable.
(These were excluded from federal AGI.):
- foreign-earned income
- income excluded by residents of Puerto Rico or American
Samoa
- proceeds from Savings Bonds used for higher education and
- employer-provided adoption benefits.
Although Railroad Retirement benefits are not taxable, one-half of the benefits received must be used to determine the amount of Social Security benefits that are taxable to Iowa. For purposes of determining taxable Social Security benefits, you must also include interest from federal securities.

Married Separate Filers:
a. If both spouses received Social Security benefits, the taxable amount is allocated between the spouses in the ratio of the benefits received by one spouse to the total benefits received. (Examples of how to prorate)
b. If only one spouse received benefits, that spouse should report the portion of the benefits that is taxable.
