If you or your spouse is registered as a taxpayer in Indonesia, a recent administrative update to the Directorate General of Taxes (Direktorat Jenderal Pajak or DJP) Coretax system may affect how your family’s tax records are managed.
From 25 January 2026, certain Nomor Pokok Wajib Pajak (NPWP) records belonging to wives registered as dependants within their husband’s family tax profile were automatically changed to non-active status. The update forms part of Indonesia’s wider effort to streamline taxpayer administration through Coretax.
For individuals, expatriate families and a business entity managing employee tax records, understanding the difference between an active and inactive Tax Identification Number (TIN) is important. This guide explains what has changed, who may be affected and what taxpayers should do next.
Key Highlights
- The Direktorat Jenderal Pajak has introduced an automatic administrative update through Coretax for certain wives whose NPWP is recorded as a dependant in their husband’s Data Unit Keluarga (DUK).
The change primarily affects married women who do not manage their tax obligations separately.
Deactivation of an NPWP does not remove the underlying financial or tax obligations of the household. - Under the consolidated family approach, the husband generally acts as the primary taxpayer, with household income reported through his NPWP.
Married women who wish to maintain separate tax reporting may use the applicable MT (Memilih Terpisah) or PH (Pisah Harta) status. - Taxpayers should review their Coretax and DUK records and ensure that their Identification Number, taxpayer status and reporting arrangements remain accurate.
Q: What exactly changed in Coretax?
The DJP updated Coretax to reflect family-based tax administration more consistently. When a wife is recorded as a dependent in the husband’s DUK profile, and the couple’s tax affairs are administratively consolidated, Coretax automatically switches the wife’s NPWP to non-active status. The change was implemented centrally and required no action from taxpayers to take effect.
Q: Who is affected by the deactivation?
The update primarily concerns married women whose individual taxpayer identification number is registered as a dependant under their husband’s family tax profile and who do not file their tax obligations separately.
The policy applies to records present in Coretax as of the implementation date; it does not target individuals for enforcement or penalties, and it is an administrative consolidation.
Q: Does deactivation cancel tax obligations?
No. An inactive NPWP is an administrative status and does not automatically eliminate tax obligations. Where a family is treated as a single economic unit, the relevant income remains subject to applicable tax regulations and must be reported accordingly.
In a consolidated arrangement, the husband generally becomes the principal taxpayer for the household, with relevant household income included in the annual tax return.
This distinction is particularly important for individuals who have employment income, investment income or other sources of taxable income.
Q: Why did the DJP introduce this measure?
The DJP has cited several administrative objectives: simplify family tax administration, reduce duplicate taxpayer records, align the database with the legal concept of the family as a single economic unit, and improve monitoring and compliance through a cleaner, integrated dataset in Coretax.
Q: What is the legal basis for the change?
The policy is consistent with existing tax law principles. Relevant provisions include Article 8 of the Income Tax Law (UU Pajak Penghasilan), which contemplates family taxation in certain circumstances, and Article 5 paragraph (1) of PER-7/PJ/2025, which addresses the merger of rights and obligations when spouses do not manage tax liabilities separately. These regulations provide the authority for consolidating family tax records in an integrated system.
Q: Can a wife still file taxes separately if she wants to?
Yes. Indonesian tax regulations continue to recognise circumstances where a married woman may manage her tax obligations separately.
Two relevant statuses include:
- Memilih Terpisah (MT) — where the wife chooses to report and manage her tax obligations separately.
- Pisah Harta (PH) — where the spouses have a legally recognised separation of assets.
Where separate taxation applies, the taxpayer’s status and supporting information should be properly recorded within Coretax and the DUK.
Q: How do I reactivate an NPWP that has been set to non-active?
Reactivation requires updating Coretax and DUK records. In practice, the steps are:
- The wife logs into Coretax and updates her taxpayer profile to indicate MT or PH status.
- The husband amends the household record in DUK to change the wife’s status to “Head of Another Family Unit (MT/PH)”.
- After synchronization of DUK and Coretax data, the wife submits a request to reactivate the NPWP through the Coretax portal.
- Once verified, the NPWP status can be restored, and the wife may file her own annual return again.
Where the online process cannot resolve the issue, taxpayers may need to contact or visit the relevant tax office for further assistance.
Q: What documents are typically needed to support reactivation or separate filing?
The required documents determined by the taxpayer’s circumstances and the basis for separate filing. Generally, supporting records may include:
- Identity card; (original or copy)
- Marriage certificate (original or copy);
- NPWP or Tax Identification Number records;
- Declaration of separate tax reporting;
- Documentation relating to separation of assets, where applicable; and
- Employment or payroll documentation from the institutions which spouses are working, where relevant.
The format and documentation requirements may vary depending on the taxpayer profile and the specific administrative request. Taxpayers should therefore check the latest requirements before submitting documents online or at a tax office.
Q: What should expatriates and foreign residents know?
Expatriate families should note that similar administrative consolidation can apply if their household is recorded in Coretax as a single economic unit.
Employers often require an active NPWP for payroll and withholding. Expatriates should confirm whether they or their spouse is registered as dependents, review residency and tax residency rules, and ensure payroll and reporting align with Indonesian requirements.
Q: What practical steps should taxpayers take now?
We recommend the following:
- Check your Coretax profile and DUK family record to see whether your NPWP has been deactivated.
- Review whether joint or separate filing best suits your situation, particularly if you have independent employment income or specific contractual obligations.
- If you need a separate NPWP, prepare documentation to support MT/PH status and follow the reactivation steps in Coretax.
- Consult your employer’s HR or payroll team to confirm how household consolidation affects withholding and reporting.
