Internal Service Fund Journal Entries

If you only read one thing An Internal Service Fund charges other departments for services, and records those charges as Revenue, using full accrual, just like a real business would.

Why This Matters

Internal Service Funds are the one fund type where a district effectively “sells” services to itself, a print shop, a central vehicle maintenance operation, and the accounting has to reflect that internal customer relationship.

What’s Actually Going On

An Internal Service Fund provides goods or services to other departments or funds within the same government, on a cost-reimbursement basis. When another department uses its services, the Internal Service Fund records Revenue, and the paying department records an Expenditure or Expense, depending on which fund it’s coming from.

Worked example: a district’s central print shop, run as an Internal Service Fund, bills the Instruction department $2,000 for printing services.
Internal Service Fund: Dr. Due from Other Funds (or Cash) 2,000, Cr. Revenues — Charges for Services 2,000
Paying fund (General Fund): Dr. Expenditures — Supplies/Services 2,000, Cr. Due to Other Funds (or Cash) 2,000

How This Applies

When you’re reviewing an Internal Service Fund’s activity, treat it the way you’d evaluate any small business, is it billing enough to cover its own costs, not just moving money around internally.
