SDI benefits are funded by employees through mandatory payroll deductions from each paycheck. Iowa, however, doesn't require employers to collect an SDI tax.

Miscellaneous Iowa Tax Information

Reciprocal Agreement(s)

Reciprocal agreements are when workers who live and work in different states are only required to pay taxes to the state where they live. Iowa currently only has a reciprocal agreement with Illinois.

As such, Illinois residents who work in Iowa will only have to pay Illinois SITs provided they submit a completed Form 44-016 to their Iowa-based employers. The opposite is true for Iowa residents who work in Illinois, but they must instead submit a completed Form IL-1040 and Form IL-W-5NR to their employers.

Paid Sick Leave (PSL) Taxes

The state of Iowa doesn’t require employers to collect PSL taxes, nor does the state have a program providing such leave to employees.

Paid Family and Medical Leave (PFML) Taxes

The state of Iowa doesn’t require employers to collect PFML taxes, nor does the state have a program providing such leave to employees.
