How does the NPPN math work for an IT consultant?

With the tenaga ahli norm (typically 50% in provincial capitals), your net income is deemed 50% × gross omzet, then taxed at the progressive Article 17 rates (first bracket 5%). Example: Rp400 million annual omzet → deemed net Rp200 million → tax computed progressively from there, less personal allowances and bukti potong credits.

How much PPh does a corporate client withhold from a IT Consultant?

Generally 2.5% (individuals are withheld under PPh 21 for non-employees — effective 2.5%; corporate vendors under PPh 23 services at 2%). Example: a Rp25.000.000 fee is withheld Rp625.000, so you receive Rp24.375.000. Without an NPWP the withholding is heavier (PPh 21 ×120%, PPh 23 ×200%).

Does a IT Consultant issue the bukti potong themselves?

No. On your sales invoice it is the client who withholds the PPh and issues the official bukti potong via e-Bupot (DJP Coretax). Your job is to make sure every withholding comes with its slip and to keep them for the annual SPT. Tagihin can only generate a draft/preview bukti potong — never an official DJP document.

Invoicing & tax for a IT Consultant in Indonesia

Q: Why can't a IT Consultant use the 0.5% UMKM final tax?

Because the profession is pekerjaan bebas (a professional occupation), which is excluded from the UMKM final-tax scheme (PP 55/2022). Instead you can use NPPN: net income deemed ±50% × gross omzet (the professional norm in provincial capitals), then taxed at the progressive Article 17 rates — after notifying the DJP of the norm election at the start of the tax year.

A IT Consultant in Indonesia counts as pekerjaan bebas (a professional), so the 0.5% UMKM final tax does not apply — your annual tax runs through NPPN: net income deemed ±50% × gross omzet (the professional norm in provincial capitals), then taxed at the progressive Article 17 rates. When a corporate client pays you, they withhold PPh 21 for non-employees (base 50% × gross × Article 17 — effective 2.5% in the first bracket, PMK 168/2023) and issue a bukti potong via e-Bupot (Coretax). Example: a Rp25.000.000 fee is withheld Rp625.000, so you receive Rp24.375.000. That slip is your tax credit on the annual SPT — you never issue it yourself.

System implementations, security audits, and advisory retainers get paid through long corporate procurement — invoice, NPWP, sometimes a stamped contract. And because consultants are pekerjaan bebas, your tax scheme differs from most freelancers: not the 0.5% final tax, but NPPN.

A worked example

Say you are a IT Consultant billing a PT client Rp25.000.000 for your work. The withholding category is “Non-employee individual (PPh 21)” at 2.5%. The figures below come straight from the Tagihin engine.

Fee (before PPN)	Rp25.000.000
Total invoiced	Rp25.000.000
Less PPh withheld 2,5%	-Rp625.000
Net the client pays (QRIS amount)	Rp24.375.000

The client withholds Rp625.000, transfers Rp24.375.000 to your account, and issues the bukti potong via e-Bupot as proof.

Your own tax: NPPN, not the 0.5% final tax

A IT Consultant is on the pekerjaan bebas list (professionals: lawyers, accountants, architects, consultants, doctors, notaries, actuaries, appraisers, certain artists), which is excluded from the 0.5% UMKM final tax (PP 55/2022). Instead you can use NPPN — the deemed-net-income norm: net income is deemed a set percentage of gross omzet (typically 50% for professionals in provincial capitals), then taxed at the progressive Article 17 rates, starting at 5% in the first bracket, after personal allowances.

Conditions: omzet under Rp4.8 billion a year and you notify the DJP of your use of the norm at the start of the tax year. The PPh 21 slips from your corporate clients become credits reducing the tax due on your annual SPT (by 31 March).

When your client is a company: withholding & the bukti potong

A company paying you must withhold PPh and remit it in your name — individuals are generally withheld under PPh 21 for non-employees (effective 2.5%, PMK 168/2023), while corporate vendors are withheld under PPh 23 (services 2%). The proof is the bukti potong the client issues via e-Bupot in Coretax. Without an NPWP the withholding jumps: PPh 21 becomes 120% of normal, PPh 23 doubles.

Who withholds: On your own sales invoice you are the payee. The client (the payer) withholds the PPh and issues the bukti potong to you via e-Bupot — not you. Your job: make sure every withholding has its slip, then keep them for the annual SPT.

What to watch for in this trade

Using NPPN must be notified to the DJP at the start of the tax year — without that notice you are deemed to have chosen full bookkeeping. Keep a tidy monthly omzet ledger; that figure is the basis of the norma computation on your annual SPT.

Documents you’ll need

Surat penawaran (quotation) — lock the scope and price before work starts
Invoice — the formal bill, with an exact-amount QRIS QR so the client just scans
Kwitansi (receipt) — proof of payment; above Rp5 million it requires the Rp10.000 meterai (Law 10/2020; e-meterai for PDFs)
Bukti potong — RECEIVED from corporate clients (issued via e-Bupot), not created by you; keep every one
