## When to register for tax collection

In Iowa, Stripe Tax supports the calculation and collection of sales tax (including seller use tax).

See the [Needs attention](https://dashboard.stripe.com/tax/locations?primary_tab=needs_attention) tab to get insights about your potential tax registration obligations in Iowa. Stripe also notifies you with email and Dashboard alerts when you need to register to collect tax. Learn more about how the [monitoring tool works](https://docs.stripe.com/tax/monitoring.md).

Remote sellers must register to collect and remit sales tax in Iowa when, in the previous or current calendar year, they exceed a sales threshold of 100,000 USD.

The threshold includes gross sales, including marketplace sales.

If your business is under the threshold, you can voluntarily register for an Iowa Retailer’s Use Tax (RUT) permit. If you’ve already registered for the RUT and exceed the economic threshold, cancel your RUT and register for an Iowa sales tax permit.

If your **head office** in the [tax settings page](https://dashboard.stripe.com/settings/tax) of the Dashboard is in Iowa, you’re not a remote seller and you must register due to your physical presence in the state.

## Register to collect tax

If you’re a remote seller, [Stripe can register with the local tax authorities](https://docs.stripe.com/tax/use-stripe-to-register.md) for you.

Register for sales tax in Iowa at the [tax authority](https://revenue.iowa.gov/taxes/tax-guidance/sales-use-excise-tax/sales-use-tax-guide).

## How we calculate taxes

Stripe calculates the taxes that apply to your customer’s location.

## Report and file your taxes
