Third Party Access (TPA) for Quarterly Filings

Guide partners to identify and resolve TPA blockers for quarterly tax filings.

This article helps Check partners understand Third Party Administrator (TPA) requirements and how they impact quarterly tax filings. Use it alongside the Blocking Report in Console to identify and resolve TPA-related blockers before filing deadlines.

🆕

What's new in Q1 2026: Check is now surfacing TPA-related blockers proactively through the Blocked Filings Report — rather than discovering them at the time of filing. You may see blockers appear earlier in the quarter than you're used to, giving you and your employers more time to resolve them.

What is TPA and why does it block filings?

Third Party Administrator (TPA) access is a state-level authorization that allows Check to file taxes on behalf of an employer with a given agency. Certain state and local agencies require that the employer explicitly grant this access — Check cannot bypass or complete it on their behalf.

If TPA access has not been granted, the employer's filing will appear as blocked in the Filing API and on the Console Blocking Report. It will remain blocked until resolved. TPA is a one-time setup per agency, but must be completed before the filing close date.

For partners:

  • Monitor the Blocked Filings Report for TPA-related blockers.
  • Communicate blockers to employers and guide them through TPA setup (see per-agency instructions below).
  • (Coming in April 2026!) Once the blocker is resolved, you can click “Remove blocker” in the Filing page in Console to remove the TPA-related blocker and queue for filing.

For employers:

  • Log into the relevant state agency portal and authorize Check as your TPA. Steps vary by agency.
  • Act promptly — some agencies may take a few days to process the request, and waiting until the deadline risks a late filing.
 

How does this relate to the closed_at date?

Check closes filings at least 8 business days before the due date. Any filing that remains blocked after the closed_at date — including due to missing TPA — will be treated as a delayed filing for billing purposes. Resolving TPA blockers before the close date avoids this.

Which agencies require TPA for filing?

The following agencies require TPA authorization for Check to file on behalf of employers. If TPA is not on file, a blocker will appear on the company's filing in the Blocking Report.

Washington: Labor & Industries (L&I)

Check files your Washington L&I taxes on your behalf, so you don't need to take any action here. In order to successfully file Washington L&I in bulk, the agency must have Check’s authorized Power of Attorney (POA) on file. It's important that your configured Experience Factor and Risk Class Codes match the agency setup. If we don’t have your POA on file and are unable to file in bulk, we'll try to file your return manually — but if your rates or class codes don't match what the state has on file, we won't be able to complete the filing and your return will be blocked.
