The “Coretax” system (Core Tax Administration System) is Indonesia’s new tax platform replacing DJP Online.<\/span> It becomes mandatory for reporting the <\/span>2025 tax year<\/span><\/b> (which you file in early 2026).<\/span><\/em><\/span><\/h3>\n

Because this is a completely new system, the process is different from the old <\/span>e-Filing<\/span><\/i> or <\/span>e-Form<\/span><\/i>.<\/span><\/p>\n

\n

Phase 1: First-Time Setup (Crucial)<\/b><\/span><\/h2>\n

If you haven’t used Coretax before, you cannot simply log in with your old credentials. You must activate the new account first.4<\/sup><\/span><\/p>\n

    \n
  1. \n

    Go to .<\/p>\n<\/li>\n

  2. \n

    Click <\/span>“Forgot Password?”<\/span><\/b> (This is how you trigger activation)<\/span><\/p>\n<\/li>\n

  3. \n

    Enter your <\/span>16-digit NPWP<\/span><\/b> (or NIK for individuals) and the Captcha.<\/span><\/p>\n<\/li>\n

  4. \n

    Check your email for a verification link from DJP.<\/span><\/p>\n<\/li>\n

  5. \n

    Create a Passphrase:<\/span><\/b> During setup, you will be asked to create a <\/span>Passphrase<\/span><\/b>.<\/span> Do not lose this.<\/b> You need it to “sign” your tax return at the end (replacing the old token code).<\/p>\n<\/li>\n<\/ol>\n

    \n

    Phase 2: Reporting the Annual Return (SPT Tahunan)<\/b><\/span><\/h2>\n

    Once logged in, follow these steps to file your return:<\/p>\n

    1. Create the Draft<\/b><\/span><\/h3>\n
      \n
    • \n

      Go to the <\/span>“Surat Pemberitahuan (SPT)”<\/span><\/b> menu.<\/span><\/p>\n<\/li>\n

    • \n

      Select <\/span>“Buat Konsep SPT”<\/span><\/b> (Create Draft).<\/span><\/p>\n<\/li>\n

    • \n

      Tax Year:<\/b> Select 2025<\/b>.<\/p>\n<\/li>\n

    • \n

      Status:<\/b> Select <\/span>Normal<\/span><\/b>.<\/span><\/p>\n<\/li>\n<\/ul>\n

      2. Verify Pre-Filled Data (The Big Change)<\/span><\/h3>\n

      Unlike the old system where you typed everything manually, Coretax automatically pulls data from your employer or banks.<\/p>\n

        \n
      • \n

        Gray Fields:<\/b> You will see many fields are grayed out. This is normal.<\/b> It means the system has already pulled this data (e.g., your salary from your office’s withholding slip\/Bukti Potong). You cannot edit these directly; if they are wrong, your employer must correct them first.<\/p>\n<\/li>\n

      • \n

        White Fields:<\/b> Fill in any missing data, such as freelance income, investments, or new assets purchased during the year.<\/p>\n<\/li>\n<\/ul>\n

        3. Complete the Attachments<\/span><\/h3>\n

        Navigate through the tabs for L-1 (Assets\/Harta) and L-2 (Debts\/Utang).<\/p>\n

          \n
        • \n

          Ensure your list of assets matches what you actually own.<\/p>\n<\/li>\n

        • \n

          Tip:<\/i> If you sold an asset, update the status here so you aren’t taxed on it in the future.<\/p>\n<\/li>\n<\/ul>\n

          4. Calculate & Pay (If “Kurang Bayar”)<\/b><\/span><\/h3>\n
            \n
          • \n

            If the calculation shows “Nihil”<\/b> (Zero balance), proceed to step 5.<\/p>\n<\/li>\n

          • \n

            If it shows “Kurang Bayar”<\/b> (Underpayment), the system will generate a billing code automatically. Pay this via your bank app, then return to this page. The system will detect the payment automatically (no need to upload the receipt manually).<\/p>\n<\/li>\n<\/ul>\n

            5. Sign and Submit<\/b><\/span><\/h3>\n
              \n
            • \n

              Click “Submit”<\/b> or “Lapor”<\/b>.<\/p>\n<\/li>\n

            • \n

              The system will ask for your Passphrase<\/b> (the one you created in Phase 1), not<\/i> your login password.<\/p>\n<\/li>\n

            • \n

              Once entered, you will receive your receipt (Bukti Penerimaan Elektronik) via email.<\/span><\/p>\n<\/li>\n<\/ul>\n

              \n
