The Revenue Administration has issued a ruling (February 25, 2025 dated ve 15584 numbered) on the treatment of tax deductions when employers are notified of private health insurance payments after the specified time frame.

The following points are summarised in this matter:

• A private health insurance policy is in effect from October 14, 2023 to October 14, 2024.
• Policy premiums are paid on time in instalments.
• Payment documents/receipts were not submitted to the employer in the months of payment but were instead provided later, in July 2024.
• The issue in question is whether the private health insurance premiums paid for the previous period can be deducted from income tax as of July 2024.
