🔒 Privacy Assured

Short version: your client's information never leaves your computer. Iowa Support Master runs entirely inside your web browser. The incomes, the parties, the children, and every financial detail you type are processed right here on your own machine.

Nothing is uploaded to us. Every calculation, every Guidelines worksheet, and the Financial Affidavit are assembled inside your browser — not on our server. Your case data is never sent to us, and it is never stored or logged on our server.

A built-in safeguard enforces this. Before any other code runs, the program installs a privacy “egress guard” that stops the browser from sending information anywhere, with only two harmless exceptions: a quick license check and a “is a newer version available?” check. Neither one carries any case data, and every other attempt to send data is automatically refused.

For your IT department. You don't have to take our word for it. Open the browser's Developer Tools, switch to the Network tab, and run a full calculation: the only requests are wismauth.cgi (license) and ism-version.json (version), and neither contains client data. The egress guard wraps the browser's three data-sending APIs — fetch, XMLHttpRequest, and sendBeacon — with a default-deny allowlist, so a third-party script cannot quietly send a case file anywhere. Blocked attempts are recorded in the browser console.

Step 3 Support Master divides the cost of coverage (above) by the Step 2 result. (0.00 divided by 0 = 0.00) This tells us the cost to cover each person, excluding the person providing the plan. 0.00

Mandatory Pension Calculator / IPERS

OVERVIEW: The amount contributed toward a mandatory pension, such as IPERS, is paid from pre-tax earnings. Therefore only the taxable portion of earnings is entered in the "Wages" field. The amount of the pension contribution is entered in the non-taxed income field.

When entering pension contributions, two things ordinarily should happen: 1. Wage income is reduced by the amount paid to the mandatory pension. 2. Nontaxable income should reflect the pre-tax payment toward the mandatory pension.

Additionally, the percentage of IPERS changes in the middle of the tax year on July 1st, so you can decide the percentage to apply to earned income for the mandatory pension.
