What are open tax years?

The term "open tax years" refers to tax years for which tax payments or obligations are still outstanding or have not been finalized. This usually means that tax returns for these years have not yet been filed or that tax matters have not yet been finalized. Open tax years can have various reasons, including outstanding tax arrears, ongoing audits by the tax authorities or late submission of tax documents. Clarification of open tax years is important to avoid potential legal consequences and to ensure proper tax management.
