If I e-file/e-pay through quickbooks online, do I still have to file with the state on their portal?

Yes, bgreenwell. QuickBooks Online automatically e-file and e-pay. 

These features depend on what product you have. If you have the Full service, Core, Elite, and Premium type of payroll, we will send and file your forms on your behalf. For the Enhanced type of payroll, you need to file/pay and submit your taxes.

Below are the listed payroll forms and taxes we submit for you:

• Forms 940 and 941. 
• Employee Wage and Tax Statement Form W-2 and W-3.
• For Intuit Online Payroll Full Service Only: Forms 1099-MISC and Form 1096.

For more details about what other taxes are paid on your behalf, please see this article: Tax Payments and Forms Intuit Payroll Submits For You.

If you're enrolled in our E-file & Pay feature, you can easily e-file payroll taxes electronically in your online payroll account. I suggest checking this article for more details: Pay and File Payroll Taxes Online.
