Due to amendments to the Tax Code, including changes to the deadlines for payment of individual income tax (IIT) by individuals engaged in private practice (IPPs), IIT for the period from January through September 2025 must be paid in a single installment no later than October 5, 2025. Since this date falls on a weekend, the payment deadline has been moved to October 6, 2025.

🔻Please note that the IS SONO system is being phased out. Therefore, you must submit the Form 270.00 Income and Property Declaration (hereinafter “Form 270.00”) through the Integrated Tax Administration System (ISNA).

🔻At the same time, until the updates are completed, the Committee recommends that private healthcare providers submit Form 270.00 declarations via ISNA after April 15, 2026.

♦️Please note that the deadline for submitting Form 270.00 for 2025 is no later than September 15, 2026.
