SAT Electronic Accounting 2026: June Trial Balance, Chart of Accounts and Acknowledgments

Updated June 8, 2026. SAT electronic accounting in 2026 should not be read as an isolated June update. It is a monthly operating obligation: a correct chart of accounts, a consistent trial balance, valid XML files and acknowledgments saved with supporting evidence.

The practical point for June is to organize the review before filing. If the trial balance is prepared at the end without reconciling CFDI, bank records, journal entries and balances, any later rejection or requirement becomes more expensive to correct.

Quick Answer

Before sending the June trial balance, confirm that the chart of accounts is current, opening balances connect to the previous closing, CFDI and bank records support relevant movements, the XML is generated with the correct schema and the acknowledgment is saved in the period folder. If something does not reconcile, fix the accounting cause before uploading the file.

If Time Is Short, Prioritize This

What Remains in Force

SAT maintains the service to send electronic accounting. The logic remains the same: certain taxpayers must submit accounting information electronically, usually through the portal or the Tax Mailbox, according to the applicable frequency and deadlines.

The 2026 rules also keep references to the chart of accounts, trial balance, journal entries, ledgers and filing rules. The right question is not whether everything changed, but whether your monthly process is documented well enough to file and support what was sent.

What to Review This Month

Before sending the trial balance, confirm five points:

1. The chart of accounts is aligned to the applicable grouping code.
2. The trial balance preserves continuity between opening balances, movements and closing balances.
3. CFDI, bank records, collections, payments and journal entries support relevant movements.
4. XML files are generated with the current schema and without inconsistent data.
5. The acceptance or rejection acknowledgment is saved with the support for the period.

If the chart changed, do not treat it as a minor file. SAT guidance indicates that the chart is sent the first time with the trial balance and also when relevant accounts are changed or added. That update should be internally documented.

Chart, Trial Balance, Entries and Acknowledgments

The trial balance is the file that usually concentrates the monthly review, but it does not stand alone. The chart explains the accounts; entries and ledgers explain movements when there is a review, refund, offset or requirement; and acknowledgments prove what was sent and when.

For management, the risk is not only technical. The real risk is that no one can reconstruct the monthly close: who generated the file, which balances were reconciled, which version was sent and what evidence was kept.

If There Was Already a Rejection or Difference

If the file was rejected or the trial balance does not match the workpapers, do not resubmit without diagnosis. Review:

1. XML structure and selected period.
2. RFC, fiscal year and file type.
3. Recent changes in the chart of accounts.
4. Opening balances against the previous close.
5. Canceled or substituted CFDI and entries without support.
6. The rejection acknowledgment and exact system message.
