Iowa payables
2026, with sources
1099s only when Iowa tax was withheld
Iowa takes W-2s and 1099s only when they show Iowa income tax withheld. The deadline for tax year 2025 forms was February 15, 2026, and they must be filed electronically through GovConnectIowa; the Department no longer accepts paper and no longer needs a separate verified summary of payments (VSP). Forms 1099-DA and 1042-S are not required even when they show Iowa withholding. Most startups paying contractors without withholding have no Iowa 1099 filing at all.
Use tax: the commercial enterprise exemption
Iowa taxes SaaS and digital products in general, but Iowa Code section 423.3(104) exempts them when bought by a commercial enterprise and used exclusively by it, with only de minimis personal use allowed. For a startup that means the SaaS stack is generally outside Iowa use tax.
Computers are not. Since January 1, 2024 the purchase of computers and peripherals by commercial enterprises for processing or storing data is taxable, so a company in Cedar Rapids that buys ten laptops from an out-of-state retailer without Iowa tax owes 6% use tax plus any local option tax on them.
Vendor checks
Uncashed vendor checks are unclaimed property, reported to the Treasurer of State by November 1.

Common questions
Do I file 1099-NEC forms with Iowa?
Only if the form shows Iowa income tax withheld. Iowa bases the requirement on Iowa withholding, not Iowa-source payments, so a normal contractor 1099-NEC with no Iowa withholding is filed with the IRS only.
Do we owe Iowa use tax on our software subscriptions?
Usually not. Iowa exempts software as a service, prewritten software and specified digital products bought by a commercial enterprise when used exclusively by that enterprise. Hardware is another matter: the exemption for computers used by commercial enterprises to process data ended January 1, 2024, so laptops bought tax-free from out of state owe Iowa use tax.
