Steps
Confirm eligibility to use Tax Pro Account, which requires recognized authority to practice before the IRS (attorney, CPA, enrolled agent, enrolled actuary, or enrolled retirement plan agent)
Sign in to Tax Pro Account after Secure Access/identity verification and select the authorization type (POA or TIA)
Enter the taxpayer's information and the specific tax matters/periods being authorized, mirroring the fields on paper Forms 2848/8821
Submit the request electronically for the taxpayer to approve in their own IRS Online Account, or use the separate 'Submit Forms 2848 and 8821 Online' tool to upload a signed PDF when the taxpayer cannot self-authorize digitally
Confirm the authorization is recorded and available for use with downstream services such as the Transcript Delivery System
Known gotchas
Tax Pro Account's real-time path only works when the taxpayer can independently authenticate and approve in their own IRS Online Account — it does not cover every representation scenario
The 'Submit Forms 2848 and 8821 Online' upload tool is processed manually on a first-in-first-out basis alongside fax and mail requests — it is electronic but not instantaneous
The IRS has not published a public machine-to-machine API for POA/TIA submission; both available paths are web-portal based
