Tax and period close are control functions. They are less about entering daily transactions and more about making sure financial treatment is configured correctly and completed periods do not keep changing without review.

​
Tax

Open Accounting > Tax for tax configuration and review where your role and workspace allow it. Tax can affect quotes, invoices and accounting postings, so changes should be made deliberately. Lynka keeps tax configuration and audit history separate from individual transaction lines. Posted invoice tax can contribute to tax payable in the ledger based on the configured mapping. Do not duplicate outdated tax rules in documentation or manually force old transactions to use a new rate without a supported correction process.

​
Close Center

Open Accounting > Close Center to work with accounting period controls. Closing a period is a financial control. It signals that the period has been reviewed and should no longer accept ordinary changes. Users need the relevant close permission, such as period.close. Before closing, review the ledger and financial statements for incomplete or inconsistent accounting. The exact checklist depends on the data in the workspace.

​
Reopening a period

Reopening should be exceptional and permission controlled. Users need period.reopen where the action is available. If a closed period must be changed, reopen it through the controlled action, make the required correction and close it again after review. That keeps the period history auditable.

Close an accounting period

Lock a completed accounting period after review so new postings cannot silently change financial history that has already been reported.

Reopen a locked accounting period only when an authorized historical correction is necessary, then review the reports affected by the change.
