Income is one of the most important financial categories in entity's operations. The financial result and profitability often depend on income. The Polish Account-ing Act and IAS 18 define income in a very similar way. The main difference is that in Polish regulations it is stressed that economic benefits should be properly sub-stantiated. IAS 18 prescribes that income should be measured at the fair value of the payment received or due.In 2008 the IASB issued a discussion paper addressing the problem of income recognition. This is a joint project of IASB and FASB, one of the priorities in the convergence plan, which should be completed by 2011.
