Tax Consultation

IBU's tax consultation engagement covers your monthly and annual tax obligations as one integrated cycle. We work alongside owners, finance directors, and in-house accountants to make sure every return is filed on time, computed correctly, and supported by the right documents.

Monthly compliance scope

• PPh 21 — employee income tax and expatriate withholding.
• PPh 22 — collection on imports and specific transactions.
• PPh 23 — withholding on services, rentals, royalties, dividends.
• PPh 25 — monthly corporate income tax installments.
• PPh 26 — withholding on payments to non-resident taxpayers.
• Final PPh Article 4(2) — rentals, construction, and other final-tax transactions.
• Output and Input VAT, including reverse-charge VAT on services from outside the customs area.

Annual filing

Preparation and filing of the annual Corporate Income Tax return with its supporting documents — fiscal reconciliation, non-deductible expense adjustments, computation of tax payable, and administration of tax credits. For individual taxpayers we prepare the 1770 / 1770S return based on the income profile.

Our approach

Every engagement is led directly by a partner. We don't push core work to junior layers. The team maps your compliance calendar, provides a month-end status dashboard, and flags regulatory changes relevant to your industry before they cost you.

What you receive

Electronic acknowledgements for every filing, a payable/refund recap, a risk-exposure summary, and a tax journal reconciled back to your bookkeeping. Everything is stored in a structured archive that holds up under audit three or five years later.
