How to Pay Taxes at Coretax DJP 2026 in 3 Main Steps

In practice, the entire tax payment process in Coretax DJP 2026 can be summarized into the following three core steps.

1. Log in to the Coretax portal using your registered NPWP or NIK.
2. Create billing codes according to the type of tax obligation.
3. Pay the billing code until you get the State Revenue Transaction Number.

These three steps apply universally to both individual and corporate taxpayers. As long as the payment results in a NTPN, the tax obligation is considered fully paid and legally valid.

How to Create a Coretax Billing Code from an Underpaid Tax Return

Billing codes are most often created when a tax return indicates an underpayment. In 2026, Coretax will automatically process this step to reduce input errors.

Practical sequence for creating billing codes from SPT in Coretax DJP 2026:

1. Prepare the draft SPT on the Coretax portal until the calculation is complete.
2. Make sure the SPT status shows Underpayment.
3. Select the billing code creation option on the SPT page.
4. The system automatically fills in the tax type, tax period, tax year, and nominal amount.
5. The billing code is stored in the active billing code dashboard and is ready to be paid.

A single billing code can cover one or more tax obligations as long as they are related to the same draft SPT. This speeds up the payment process and minimizes the risk of incorrect payments.

How to Create a Mandiri Billing Code in Coretax DJP 2026

Not all tax payments originate from the SPT. For certain obligations, Coretax DJP 2026 provides for the creation of independent billing codes.

Payments that generally use the Mandiri billing code:

1. Income Tax Article 25 installments.
2. Final PPh paid by yourself.
3. Tax deposit payment.
4. Certain tax payments that do not require an SPT.

Quick steps to create a Mandiri billing code:

1. Go to the Payment menu in Coretax.
2. Select the independent billing code creation service.
3. Specify the Tax Account Code and Deposit Type Code.
4. Select the tax period and enter the payment amount.
5. Confirm until the billing code is issued.

Mandiri billing codes have a validity period of seven days. If the validity period is exceeded, the code cannot be used and must be regenerated.

How to Pay Coretax Billing Code to Get NTPN

All unpaid billing codes can be accessed via the active billing code dashboard in Coretax DJP 2026.

Stages of billing code payment in Coretax:

The 2026 tax payment method via Coretax by the Directorate General of Taxes (DGT) reflects Indonesia's fully integrated digital tax system. The process is streamlined, data is consistent, and every transaction is clearly traceable.
