Tilitason

Tilitason is a Finnish term that literally combines tili ("account") and taso ("level"), and is used to refer to the level or layer within an account structure. In accounting and financial software contexts, tilitason denotes the degree of granularity at which transactions, balances or reports are maintained and presented. The concept helps organize chart of accounts entries into hierarchical levels so that information can be aggregated for summaries or drilled down for detail.

Usage of the term appears most often in bookkeeping, enterprise resource planning (ERP) systems and financial reporting, where organizations define multiple tilitasot (account levels) to meet internal control, regulatory and management reporting needs. Depending on practice and system design, levels may correspond to major account classes, subaccounts, cost centers or project codes; the number and naming of levels vary by country, industry and organizational size.

Because tilitason is a descriptive term rather than a standardized technical specification, its exact meaning and implementation are context-dependent. In practice, clear documentation of the chosen account hierarchy is important to ensure consistent posting, consolidation and retrieval of financial information. Related concepts include chart of accounts, account hierarchy and general ledger.
