 S Corp Tax Returns

If you’re an S Corporation, it’s important to note that your income tax returns are due by March 15th of each year (September 15th with extension). Our team can assist you with preparing and filing Form 1120-S, related state filings, and even help you make the S Corp election if you missed the deadline. Don’t stress about tax season - let us handle the details for you.

This includes:

  • Preparation of the S Corporation Tax Return package which includes Form 1120-S, related state returns, and form K-1

  • Electronic filing of federal tax return to IRS

  • Electronic filing of state tax return(s) to the relevant state authorities (if applicable)


  • Federal Filing Only: $675*

  • Federal Filing + 1 State: $750*

  • Federal + Multiple States: Contact us

  • Referral Code: OPTR24

* Please note that cryptocurrency tax reporting, financial statement preparation (profit & loss/balance sheet) are not included in our standard preparation and filing service. You can find more details about our cryptocurrency tax packages and full service list on our Services page.

If you do choose to engage in additional services beyond S Corporation tax preparation and filing, we will happily apply a 10% discount off our normal pricing.
