Cook the books

informalUS and UKMoney idiomsHonesty and secrets idioms

To cook the books is to change financial records dishonestly, usually to hide losses, take money or make a business look healthier than it is.

How people use it

People use it about companies, clubs or individuals who fake accounts, tax records or sales numbers (the treasurer had been cooking the books for years). It is informal but appears often in news reports about fraud. It always suggests deliberate dishonesty, not an honest error. Books here means account books, the records of money coming in and going out. A related term, creative accounting, can describe tricks that are misleading but not always illegal.

Examples

Where it comes from

'Cook' has been used to mean alter, fake or tamper with something since at least the 1600s, the idea being that you take raw facts and prepare them to suit your taste. Account books were an obvious target. Cooked accounts were mentioned long ago, and the catchy phrase cook the books grew common in the 1900s.
