Before Ordering Permits/Registrations

  • There are several reasons why our process is the most completed and efficient. Since we started registering thousands for sales tax back in 2015, we have improved our master sales tax application to simplify the process and information we need from you. Our application is secure and encrypted. Our master application will autofill the other state forms, whether we need to mail in an application or use the information to apply online. Since we are applying daily, we are in constant contact with the various state departments of revenue and keep up with the important updates and changes (which are constant). Our instructions (both written and video overview) will help explain each step of our application and process, so you can focus your time on your business, not sales tax registration. All your login details for your tax accounts that we set up are saved in a secure area for easy future access. When you are ready to re-order more state sales tax permit registrations, you will have access to your saved application to add the states you need vs. having to start from scratch and complete the entire application.

  • Our sales tax application will provide guidance and clear examples to help you determine when you first had nexus, your start date, and costly application mistakes to avoid. If you need support with a sales tax nexus study, to provide you with a clear and accurate report, recommended states, and time frames to register, we provide those services.

  • After payment, you will receive our welcome email with a link to both our sales tax system agreement (a review of our 10-step process) and our sales tax application. The sales tax application is where you will select the states where you would like us to register your business. Our sales tax application includes very clear instructions and examples for each section. We have consolidated all the questions over the years to improve our instructions and video training, to make this easy for you. Once you submit our sales tax application with your selected states, our advanced sales tax team will carefully review your sales tax application and follow up for clarification or suggested changes before we move forward to apply. Separately, we will send you a separate payment link with the state fees to pay.

  • You will have a credit of three permits on your account. This is common, because as you go through our process, you may find you are unable to or not ready to apply in a state (for example, a state that requires an ITIN for the responsible party to register).
  • When you are ready for more permits in the future, we will check your account for any available credits.

  • Yes. If you do not have an EIN/FEIN, we are able to provide that separate service for you.

  • No, but recommended. On average, you may receive 3-5 pieces of mail to sort and organize per state over the first three months. Most mail may be information or past returns to file, but some will be important notices in relation to your sales tax account, past sales tax due, or delinquent notices. We recommend our Virtual Address Service with scanning for all sellers. Learn more here

During the Ordering Permit/Registration Process

  • Here is our 8-step process overview Go to this link . You will receive our welcome email with a link to your Sales Tax Agreement and Sales Tax Registration Application to complete online. Once submitted, our team will review and follow up with a link for the state fees to be paid.

  • Any questions about our process, applications, and next steps provided are included. We provide a video overview and examples on our application to simplify the process to register. If you need support for other services, including EIN, virtual address service, U.S. entity formations, U.S. banking, foreign qualifications, sales tax research, sales tax nexus evaluation… all are separate.

  • Yes. We know how busy you are growing your e-commerce business. Our services have automatic campaign follow-ups and reminders to help you stay on track. Each email lets you know which step of the sales tax permit registration process is next. Once we receive your complete agreement and application, a tag set in our system by our team will stop follow-up reminders.

  • This is the date you first had nexus in a state (either physical or economic are most common) and had sales to customers in those states.

  • Yes, there are two states that require a SSN or ITIN (and this may change in the future). If you select these states and don’t have an ITIN, we do have a recommended resource to obtain one. If you decide not to obtain one in a state, we would be unable to move forward. This is part of our review process.

  • The process may vary from the time your sales tax application is received, reviewed and state fees are paid. Time frame with an SSN (when we are able to apply online) is from 1-3 weeks, and without an SSN or ITIN and when mailing or faxing is required, maybe 4-8 weeks.

After Permit/Registrations are Completed

  • Yes. There are a couple of states that require foreign qualification before applying for sales tax, and we provide a separate service for that process. There are some states where it is recommended to foreign qualify based upon the state’s view of collecting and remitting sales tax being considering doing business in the state. Some states do cross check between the department of revenue and Secretary of State. Our sister company, NCP, has been performing entity formation, as well as all the steps involved with foreign qualification since 1997. This is a continuously changing process as the states evaluate this moving target, but we will keep you updated as a client.

  • Yes. We provide the steps for the most common marketplaces to update your tax settings (as needed). There are some states where the marketplace facilitator collects on your behalf.

  • We have remitting partners that will support you with filing any past returns, as well as remitting moving forward.

  • Yes. This is a moving target with bank changes over time. Travel is required and our fees to facilitate this process are separate. Most banks require an ITIN or local utility bill. Operating with a U.S. entity vs a foreign entity makes a big difference also. The best part is we have the most updated options available. Our remitting partners recommend a U.S. bank account with an ACH pull to automate the filing of your sales tax returns with the states.

  • Yes. We work with a few different tax firms (and tax attorneys as needed) that will quote you a fee to file any required state tax returns.
