Article summary

Sales Tax Autofile is the sales tax autofiling service provided by Sidr Tax. We use the sales tax reports generated from your Shopify transactions and file the state returns for you. Enroll in each state separately, and rest assured that your sales tax filing will happen on time.

How to setup Sales Tax Autofile

Activate Sales Tax Autofile

First, go to the Sidr Tax Autofile page. If this is the first time you access the Sales Tax Autofile feature, you need to activate it first. The autofile feature is available to all plans, including the free plan. The feature activation requires authorization to charge a maximum of $1000 monthly. This is not an estimate of how much you will pay. The cost of autofiling varies from $35 to $45 per file depending on your plan, and you will only be charged after a successful file. The increased maximum charge is to ensure that Sidr Tax can continue to file for you if the number of your autofiling states increases.

Select Nexus States

Your business is required to collect and file sales tax once you reach the Nexus status in a state. Each state has different requirements for reaching the Nexus status. To understand those requirements, you can visit this help article here. If you need help registering with a state, we can also provide you with assistance. Please reach out to us at

Once you have registered and started collecting tax in a state, you can add the Nexus info into Sidr Tax. Click on the Add New Nexus State button, and choose the state and filing schedule. Sidr Tax uses this information to determine when you need to file, and keep you on schedule.

Add New Nexus State

Enable State Autofile

Once you have chosen your Nexus states, you can start providing the necessary information for autofiling. Each state has different requirements to enable autofiling, and Sidr Tax will guide you on what to provide. All the fields are required to finish the setup, and if you are unsure what to provide for a field, please chat with us in the app or send us an email at We are happy to assist you.

Autofile Configuration

After you finish providing Autofile information, the Sidr Tax team will start validating the information. We will reach out to you if there are additional steps needed. For example, certain states require granting third-party access to your Department of Revenue account, and we will walk you through how to set it up. We will typically reach out to you within 24 hours if there are additional steps needed.

Provide Payment Information

Sidr Tax will never use this payment account to collect service charges, since all Sidr Tax payments go through Shopify. Please click on the Add Payment Information button to add the payment information.

Once you are done, send the form to
