1. Introduction – What is Publication 5629?
Internal Revenue Service (IRS) Publication 5629, officially titled “Fact Sheet: TaxSlayer Pro Closeout/Backup Procedures for SPEC Partners,” is an operational instruction manual for volunteer tax preparation sites. Carrying IRS Catalog Number 92856M, this document establishes mandatory data preservation and cybersecurity standards when tax sites close their doors at the end of a filing season.
Official IRS catalog listings confirmed in 2026 verify that the active operational framework governing tax sites preparing for and operating through the 2026 tax filing season is Revision 4-2025, which was posted by the IRS on April 8, 2025, and maintained through official IRS directory reviews in August 2026 and October 2026. This fact sheet ensures that partner sites properly secure sensitive taxpayer records and preserve essential carryforward data needed for filing season 2026.
The guidance is issued specifically by the IRS Stakeholder Partnerships, Education and Communication (SPEC) organization. SPEC is the outreach and education division of the IRS Wage and Investment Division that oversees nationwide community tax assistance networks.
2. Who Should Read This Publication
Publication 5629 is primarily written for leadership and administrative staff at free tax preparation sites across the country. It is essential reading for anyone with administrative privileges or technical duties at an IRS partner site.
- Site Coordinators: Leaders responsible for operational oversight, managing volunteer access, and ensuring overall site compliance.
- Site Administrators: Individuals who manage user accounts, assign software permissions, and oversee configuration settings in tax software.
- Volunteer Income Tax Assistance (VITA) Partners: Organizations offering free tax help to people who generally make moderate-to-low income, persons with disabilities, and limited English-speaking taxpayers.
- Tax Counseling for the Elderly (TCE) Partners: Groups specializing in tax assistance for seniors aged 60 and older, including AARP Foundation Tax-Aide programs.
- Technical Support Volunteers: IT coordinators tasked with data archiving, hardware storage, and machine sanitization.
3. Key Topics Covered
Publication 5629 provides step-by-step instructions that address end-of-season software management and hardware compliance. Its core topics focus on protecting taxpayer information and preparing software for upcoming tax years.
- TaxSlayer Pro Online Closeout: Detailed guidelines on managing client return statuses and freezing volunteer access.
- Preparer Account Deactivation: Instructions for using administrative toggles to prevent off-season software access.
- TaxSlayer Pro Desktop Closeout: Contingency planning, directory size verification, and local data backup.
- Hardware Sanitization: Mandatory “disk wipe” procedures required before returning IRS-loaned computer equipment.
- Disaster Recovery Protocols: Creating reliable, encrypted backups to prevent data loss from physical damage or system corruption.
4. Detailed Breakdown of Main Concepts
The instructions in Publication 5629 are split based on whether a partner program uses the cloud-based web application or the locally installed desktop program. Both paths enforce strict controls over data access and storage.
TaxSlayer Pro Online Protocols
For cloud-based sites, client records are stored securely on remote servers, which simplifies basic data retention. However, site administrators must handle user access with extreme care at season close.
First, administrators must never manually deactivate client tax returns if they want carryforward tax data for the next filing season. The TaxSlayer server automatically protects this information and carries relevant taxpayer history forward into the 2026 tax software.
Second, administrators must navigate to the Configuration Menu under Preparer Setup and adjust user access. Administrators must use the “Flip Active Status” tool to make all volunteer preparers inactive simultaneously. Only the primary site administrator named on the software license remains active to perform off-season administrative work.
TaxSlayer Pro Desktop and Contingency Protocols
Sites that run the locally installed desktop application are responsible for manually backing up their entire database. If local records are not backed up before the close of the season, carryforward data will not be available for the 2026 filing season.
Administrators must verify the file size of the TaxSlayer directory on their local hard drive using File Explorer. They must then connect a dedicated removable USB storage drive, such as a high-capacity flash drive or external portable hard drive, with sufficient free storage space.
The publication explicitly prohibits the use of CD-ROMs or DVDs for these backups because optical media lack adequate capacity and reliability. After creating the primary backup, any temporary data placed on secondary or staging drives must be permanently deleted and the computer recycle bin emptied.
| Feature / Task | TaxSlayer Pro Online | TaxSlayer Pro Desktop |
|---|---|---|
| Data Storage Location | Secure cloud servers managed by TaxSlayer | Local computer hard drives (C: drive) |
| Carryforward Preservation | Leave all returns active; server stores them automatically | Manually back up the entire application folder to external media |
| User Access Management | Use “Flip Active Status” to deactivate all volunteers | Lock down workstation logins and secure the physical machine |
| Backup Storage Media | Cloud-managed database backups | USB flash drive or portable hard drive (CD/DVD strictly banned) |
| Off-Season Access | Restricted strictly to the designated Site Administrator | Restricted strictly to authorized physical hardware custodians |
IRS Computer Depot Equipment Protocols
Many VITA and TCE sites borrow computers directly through the IRS Computer Loan Program. Publication 5629 requires strict compliance with Publication 4473, the IRS Computer Loan Program Welcome Package.
Before any loaned laptop is shipped back to the IRS Computer Depot, site managers must run a Department of Defense-grade disk wipe. This complete software sanitization completely destroys all residual data, operating files, and any stored Personally Identifiable Information (PII).
5. Practical Examples or Scenarios
Scenario 1: Closing a University VITA Clinic
A university accounting department hosts a weekly VITA clinic that concludes its operations on April 15. The site coordinator oversees 25 student volunteers who prepared returns using TaxSlayer Pro Online.
Following Publication 5629, the site coordinator logs into the administrative console rather than deleting user accounts one by one. The coordinator selects “Flip Active Status” in Preparer Setup, instantly turning off access for all 25 student accounts while retaining their own administrator login. The coordinator leaves all client files untouched, ensuring returning clients can have their basic details carried forward into the 2026 season.
Scenario 2: Managing a Mobile Rural Senior Center
A rural non-profit operates a mobile TCE clinic using TaxSlayer Pro Desktop on five IRS-loaned laptops. Because the community center lacks steady internet access, all tax returns were saved directly to each laptop hard drive.
At the end of the season, the IT volunteer inserts a secure USB flash drive into each computer, copies the complete software folder, and verifies the file count. Once the backups are safely locked away in a fireproof safe, the volunteer runs the official disk wipe utility on each laptop before boxing them up for return to the IRS Computer Depot.
6. How This Publication Relates to Specific Forms
Although Publication 5629 is an administrative fact sheet rather than a filing schedule, it directly safeguards the preparation of key tax forms.
- Form 1040 and Form 1040-SR: The U.S. Individual Income Tax Return and its senior counterpart. Publication 5629 safeguards the intake and carryforward numbers that populate these returns year after year.
- Form 13614-C (Intake/Interview & Quality Review Sheet): The foundational intake document where taxpayers record their Social Security numbers, banking details, and dependent information. Publication 5629 ensures this private data never lingers unprotected on local hardware.
- Form 13615 (Volunteer Standards of Conduct Agreement): The ethical agreement signed by all volunteer tax preparers. Adhering to Publication 5629 helps site coordinators satisfy the data confidentiality rules mandated by this form.
- IRS Publication 4473: The guide governing loaned IRS hardware, which outlines the specific disk-wiping software standards cited in Publication 5629.
- IRS Publication 4299: “Privacy, Technology, and Security Guidelines for SPEC Partners,” which provides the comprehensive federal privacy framework that Publication 5629 enforces operationally.
7. Common Misunderstandings Clarified
Several frequent misconceptions exist regarding what happens when a community tax site shuts down for the summer.
Misunderstanding 1: Deactivating client returns helps “clean up” the database.
This is an incorrect and damaging action. Deactivating a completed tax return breaks the carryforward link, meaning returning clients will have to manually re-enter all demographic, dependent, and prior-year tax figures during the next filing season.
Misunderstanding 2: Deleting software shortcuts or uninstalling the program wipes taxpayer data.
Uninstalling an application often leaves database files intact on the hard drive. For loaned hardware, coordinators must perform a true disk wipe as specified in Publication 4473 to securely overwrite all sectors of the storage drive.
Misunderstanding 3: CD-R or DVD-R discs are acceptable for Desktop backups.
The IRS explicitly forbids writable discs for desktop backups. Optical discs are vulnerable to data corruption and scratching; sites must use USB-connected storage drives.
Misunderstanding 4: Leaving volunteer logins active during the off-season is harmless.
Active credentials pose a serious security vulnerability. If a volunteer computer is compromised or an account accessed during the off-season, bad actors could view sensitive taxpayer records. Setting accounts to inactive neutralizes this risk.
8. Why This Publication Matters for Taxpayers
Most taxpayers never read Publication 5629, yet they benefit directly from every rule outlined inside it. Millions of working families, seniors, and students trust volunteer programs with their most sensitive personal details.
By enforcing universal account closures, the IRS eliminates unauthorized access to taxpayer files between filing cycles. This dramatically reduces the chances of identity theft, fraudulent refund claims, and unauthorized data breaches.
Furthermore, reliable backup procedures guarantee continuity of care. When seniors or working parents visit their local community center the following year, their basic tax details load smoothly, saving them time and reducing clerical errors on their returns.
9. Frequently Asked Questions
What is the difference between TaxSlayer Pro Online and Desktop closeout?
TaxSlayer Pro Online saves return data directly to secure cloud systems, so coordinators only need to inactivate volunteer logins. Desktop versions store files on local hard drives, requiring managers to create external USB drive backups and perform physical data wiping.
Can volunteer preparers log into TaxSlayer during the off-season?
No. When site coordinators implement the “Flip Active Status” rule, volunteer accounts are suspended. Only the designated site administrator retains active access to handle administrative updates or respond to rare post-season filing inquiries.
Why are CDs and DVDs banned for Desktop data backups?
Optical media are easily damaged, have limited storage space, and can fail during reading or writing. USB flash drives and portable hard drives offer higher capacity, faster transfer speeds, and superior physical durability.
What happens to taxpayer data stored on loaned IRS laptops?
All data on loaned laptops must be permanently destroyed using certified disk wipe software before the computers are returned to the IRS Computer Depot. This guarantees that no personal tax information remains on the hard drive.
Do site administrators have to create individual backups for each client?
No. In the Desktop version, administrators back up the entire application directory in a single operation. In the Online version, client data is automatically preserved in the cloud without requiring individual manual downloads.
10. Conclusion
IRS Publication 5629 serves as an indispensable safeguard for community-based tax preparation programs. By establishing rigorous post-season closeout steps, the IRS protects sensitive taxpayer identities and maintains clean records across both web and desktop environments.
For site leaders and volunteers preparing for or concluding tax filing activities, following these instructions is both a procedural duty and a commitment to taxpayer trust. Reviewing user lists, locking inactive accounts, and maintaining reliable backups ensures that your tax site remains safe, compliant, and ready for future filing seasons.
