Unreturned / Appropriated Interest on Inmate Trust Balances
Definition
Correctional agencies and their depository banks often retain the interest earned on inmate trust accounts instead of crediting it to the inmates whose funds generated that interest. Over large inmate populations and multi‑million‑dollar aggregate balances, this creates a recurring, systemic skim of interest that is legally contested and not transparently treated as program revenue.
Key Findings
- Financial Impact: In California, litigation over interest on prison trust accounts involved class claims on tens of millions of dollars of principal balances, with interest value estimated in the millions of dollars over multi‑year periods; similar programs in other large systems (e.g., CDCR, BOP, state DOCs) managing 6–9 figure inmate balances imply recurring annual interest diversion easily in the low‑ to mid‑seven‑figure range per large system.[5][7]
- Frequency: Daily
- Root Cause: Ambiguous legal status of inmate trust accounts and a lack of explicit fiduciary rules allow prisons or state funds to retain or redirect interest income generated by pooled inmate deposits, creating an ongoing revenue leakage from inmates’ equitable property that is not treated as a liability back to each account holder.[5][7]

Financial Impact
$1,200,000 - $8,500,000 annually (mid-large county system with $80M-$250M aggregate inmate balance at 1.5%-3.4% interest rates; interest retention is standard practice) • $1.5M - $7M annually per large correctional system (estimated from multi-year class action settlements and ongoing interest diversion on 6-9 figure aggregate balances) • $100,000–$600,000 annually (ICE detainee population: 10,000–20,000 × $60–$150 average balance × 1.5–2.5% interest)
Current Workarounds
BOP Trust Fund Manual procedures rely on manual corrective action identification; TRULINCS system generates weekly reports but interest calculation is separate • ICE contractor accounting system (often third-party vendor-managed) retains interest as 'custody fee'; ICE Accounts Manager aware but defers to contractor policy; minimal oversight • Manual cross-referencing of confiscation logs with trust account ledgers; Excel sheets tracking confiscated fund dispositions; unclear whether interest on confiscated funds is being credited or absorbed
