Conclusion; ReferencesThe paper discusses the improvements which a semi-autonomous revenue agency (SARA) must make to its records to meet fiscal and financial accounting obligations. SARAs are legal entities, such as a service or a department, which are required to prepare accrual records that may diverge from a treasury's cash accounting records. Their records reflect revenues generated; budget funds for generating the revenues; and material programs administered for other agencies. The accounting records and financial statements (income statement, balance sheet and cash flow statement) must conform to generally-accepted accounting principles (GAAPs) or standards such as the International Public Sector Accounting Standards (IPSAS) of the International Federation of Accountants (IFAC)-and to the treatment of operating, investment and financing activities in the Government Finance Statistics (GFS) Manual.IMF Working Papers; Working Paper ;No. 2008/116AccountingStandardsFinancial statementsStandardsTax administration and procedureAccountingimfBudgetingimfMacroeconomicsimfPublic AdministrationimfPublic Sector Accounting and AuditsimfNational BudgetimfBudget SystemsimfPersonal Income, Wealth, and Their DistributionsimfPublic finance accountingimfFinancial reporting, financial statementsimfBudgeting & financial managementimfFinancial statementsimfFiscal accounting and reportingimfAccrual accountingimfBudget planning and preparationimfPersonal incomeimfFinance, PublicimfBudgetimfIncomeimfSouth AfricaimfAccountingStandards.Financial statementsStandards.Tax administration and procedure.AccountingBudgetingMacroeconomicsPublic AdministrationPublic Sector Accounting and AuditsNational BudgetBudget SystemsPersonal Income, Wealth, and Their DistributionsPublic finance accountingFinancial reporting, financial statementsBudgeting & financial managementFinancial statementsFiscal accounting and reportingAccrual accountingBudget planning and preparationPersonal incomeFinance, PublicBudgetIncome657.0218Terkper Seth1464027DcWaIMFBOOK9910788246803321Accounting Challenges for Semi-Autonomous Revenue Agencies in Developing Countries3673577UNINA
