Idaho Went Two Years Without Reconciling Its Own Cash Balance

When Idaho switched its state government onto a new accounting system called Luma on July 1, 2023, the Office of the State Controller stopped doing something basic: reconciling the cash balance in its books against the balance at the bank.▸ Two full fiscal years later, Idaho's Legislative Services Office⧉ says that gap still hasn't closed. As of May 21, 2026 -- the date auditors signed off on the state's fiscal year 2025 financial statements -- the Controller's Office had shown no evidence of a single completed cash reconciliation covering either fiscal year 2024 or fiscal year 2025.

The consequence of skipping that check showed up almost immediately.▸ Auditing the fiscal year 2024 statements⧉, auditors found a journal-entry template at the Idaho Department of Health and Welfare had its debits and credits reversed -- a template error that overstated Pooled Cash by $433.6 million and other accrued liabilities by $280.7 million in the draft statements submitted for audit, plus a further $152.9 million overstatement to reported revenue. The errors were corrected before the ACFR was published, but only because they were big enough to trip the audit's own materiality threshold. Auditors were blunt about why nobody inside state government caught it first: a working reconciliation "would have increased the chances that the Office would have identified the errors in the journal entry when cash balances did not reconcile to the bank" -- the exact process Luma's rollout had discontinued.

A separate failure mode hit the state's actual payments, not just its books.▸ In November 2023, a bug in the interface that sends payment files to the bank reprocessed a prior day's records, issuing duplicate payments to Medicaid providers totaling roughly $30 million. None of those duplicates were ever recorded in Luma -- the state only found out because providers started calling to ask about the extra money. A second, smaller incident at the Division of Human Resources put out more than $550,000 in duplicate payments; auditors caught that one only because the Controller's Office tried to fix it by billing another agency rather than filing the legislatively-approved correcting entry Idaho law requires for errors that size.

The fiscal year 2025 audit⧉ found 10 material weaknesses and 4 significant deficiencies in Idaho's statewide books, down from 11 and 8 the year before.▸ But the improvement is narrower than the headline count suggests: the two most consequential FY2024 findings didn't close, they recurred under new numbers. The discontinued cash reconciliation is now Finding 2025-102. And the Office's inadequate data-reconciliation process, auditors wrote, "continues to allow duplicate payments to occur" -- a second incident hit in fiscal year 2025 when the same payment interface was stopped mid-run to fix a remittance-advice problem and restarted, producing double and sometimes triple payments. This time, the state couldn't even total what went out the door: because the duplicates were recorded in Luma only once, auditors cited "the inability to identify or track the erroneous payments through Luma" itself. The Idaho State Treasurer's Office had to hunt down and recover the money by hand, using a spreadsheet.

The fix took a while.▸ The Controller's Office designed an automated script to compare incoming payment records against recent prior ones and block duplicates before they go out -- but auditors say it wasn't tested until April 2026 and had not been implemented for the audit period that ended June 30, 2025. In its place, the office started running a quarterly (not continuous) manual data-validation check in April 2025. Auditors' verdict on that stopgap: "Data validation on a quarterly basis is an improvement, however, identifying errors and making corrections in a timely manner may prove more difficult with such large time frames."

Idaho didn't stumble into Luma.▸ The Legislature funded it in 2018 on the strength of a study projecting $212 million in savings by the tenth year after go-live, from retiring older duplicate systems, tightening purchasing and accounts-receivable practices, and freeing up HR and finance staff. Idaho's own Office of Performance Evaluations⧉ checked that promise in October 2024, after the first full year of live operation, and reported the state had already spent $117 million building and running Luma -- against an original 2018 estimate of $102 million -- with a total cost projected to reach $220.8 million by 2034. In OPE's own survey of state fiscal officers and directors, 78% said their agency had realized no savings from the switch; only 3% reported any.
