After your EIN in Arkansas
| Account | Agency | Number you get | Register |
|---|---|---|---|
| State income tax withholding | Arkansas Department of Finance and Administration | Withholding account ID | ATAP |
| Unemployment insurance | Arkansas Division of Reemployment | Employer Account Number (EAN) | Tax21 |
| Sales tax | Arkansas Department of Finance and Administration | Sales tax permit | ATAP |
Arkansas gives each kind of withholding account its own account ID: wage, pension and pass-through withholding are separate accounts. Use the right ID on each, and if the business gets a new EIN, close the old withholding account and register again on Form AR-1R.
Arkansas will not issue a new sales tax permit while other tax liabilities are outstanding. The Department of Finance and Administration requires them to be cleared first, so settle any open state tax balance before you apply through ATAP.
Also on the Arkansas list
- Register with the Arkansas Department of Finance and Administration through the Arkansas Taxpayer Access Point (ATAP) for the state tax accounts the business needs, such as a sales tax permit; the Department directs businesses not already filing in Arkansas to register for state taxes there.
- File the Annual LLC Franchise Tax Report with the Secretary of State on or before May 1 every year. Each report covers the calendar year that ended the previous December 31, so an LLC formed this year files its first report by May 1 of next year.

What is different about Arkansas
- Arkansas LLCs do not file a separate annual report. The annual franchise tax report, filed with and paid to the Secretary of State rather than the tax department, serves as the annual report, and it is due on or before May 1 with no extensions; Arkansas eliminated franchise tax extensions by statute in 1991.
- The Secretary of State's online franchise tax system asks for two things: the LLC's filing number and the federal tax ID on file with the Secretary of State. A company in its first year to file, or with no EIN on record yet, enters nine zeros instead, and the paper report carries its own Federal Tax ID line for the EIN.
- Arkansas franchise tax keeps accruing even after the state revokes an LLC for not paying, and it continues until the company is formally dissolved, withdrawn or merged. Under Arkansas law the Secretary of State also refuses other business filings from an entity that has not paid, so an LLC that is simply abandoned keeps running up a balance.
Before you apply
The SS-4 must match the Arkansas Secretary of State filing; its filing number is a state index, not a tax ID.
Arkansas EIN questions
How do I get an EIN number in Arkansas?
File IRS Form SS-4 after the Arkansas Secretary of State approves any formation filing; there is no Arkansas EIN application. Then register with the Arkansas Department of Finance and Administration (ATAP) for withholding and the sales tax permit and the Arkansas Division of Reemployment (Tax21) for unemployment insurance.
Is there an Arkansas EIN or state tax ID number?
No; only the IRS issues EINs (also called the FEIN or federal tax ID). Arkansas's own numbers are the filing number from the Arkansas Secretary of State, the withholding account ID from the Arkansas Department of Finance and Administration, the Employer Account Number (EAN) from the Arkansas Division of Reemployment, and the sales tax permit from the Arkansas Department of Finance and Administration.
Is the Arkansas withholding account ID the same as my EIN?
No. The Arkansas Department of Finance and Administration assigns it when you register as an employer in ATAP. It goes in W-2 box 15; the EIN goes in box b.
Where do I register for Arkansas unemployment insurance?
With the Arkansas Division of Reemployment, online through Tax21. It assigns an Employer Account Number (EAN), a separate number from the EIN.
Do I need an Arkansas sales tax permit?
Only if you sell what Arkansas taxes. The Arkansas Department of Finance and Administration issues it through ATAP, and your returns are filed under its number, not the EIN.
