If you are the designated official for your S corporation or C corporation's IRS Business Tax Account (BTA), your access expires unless you revalidate between June 15 and July 29, 2026. The IRS made the BTA the primary self-service portal for corporate tax balances, federal tax deposits, and Income Verification Express Service (IVES) transcript approvals — and it now requires annual revalidation to keep it.
Who Must Revalidate
The revalidation window applies to anyone who registered in 2025 as a designated official for an S or C corporation in BTA. A designated official is the person who can legally bind the entity for tax purposes — typically an officer, partner, or owner listed on the corporate return.
Partnership designated officials have a separate fall window (six weeks starting October 15). Sole proprietors do not use the designated-official role.
If you miss the July 29 deadline, you lose designated-official access and must request access again — either as a designated official or as another user type — with fresh identity proofing.
What Revalidation Requires
To revalidate, log in to BTA during the window and e-sign to confirm your role. You will need:
- A W-2 for the most recent tax-filing year showing wages from the corporation, or proof you can legally bind the entity (articles of incorporation, bylaws, or a corporate resolution)
- Identity verification through ID.me if your session has expired
- E-signature acceptance of the designated-official responsibilities
The process takes a few minutes if your W-2 is available and your BTA profile is current. If your corporate address or officer list has changed since registration, update it before revalidating — a mismatch between your W-2 and the IRS master file is the most common reject.
What You Lose If You Miss It
Without designated-official access you cannot:
- View or pay the corporation's tax balances in BTA
- Make federal tax deposits (FTDs) through BTA
- Approve or reject IVES transcript authorization requests from lenders
- Download the EIN verification notice (CP 575) that banks often request instead of Letter 147C
You can still pay through EFTPS or Direct Pay, but you lose the consolidated view and the IVES workflow that mortgage and SBA lenders increasingly require.
Bookkeeping Checklist Before July 29
- Confirm who is the designated official. If the officer listed left the company, revoke their access and register the current officer now — do not wait for the revalidation window.
- Collect the W-2. For an officer who takes no W-2 wages (common in early-stage S corps), prepare the binding-authority document now.
- Calendar annual renewal. Revalidation is annual. Add a recurring task for June 15 each year so the window never surprises you.
- Document in your ledger. Track BTA access as an operational control: who holds it, when it was revalidated, and the next due date. In Beancount, a dated note or custom directive keeps it auditable.
Simplify Your Financial Management
BTA is where tax balances meet banking. Losing access at quarter-end because a revalidation lapsed is an avoidable fire drill. Beancount.io keeps corporate tax, payroll, and deposit postings version-controlled — so when you revalidate BTA, the books you reconcile to are already clean.
