Selling a car in Indonesia requires two key vehicle documents — the BPKB and the STNK — and a formal ownership transfer process (balik nama) at the local Samsat office. Getting these in order before listing makes the sale straightforward and prevents the most common disputes.
BPKB — Vehicle Ownership Book
The BPKB (Buku Pemilik Kendaraan Bermotor) is the vehicle ownership book — the primary document that establishes legal ownership of a car in Indonesia. It is issued by the National Police (Polri) and must be handed to the buyer.
- Original required: Only the original BPKB is valid — photocopies are not accepted for ownership transfer.
- No outstanding loans: If the vehicle was purchased on leasing (leasing/kredit), the BPKB is held by the financing company (leasing company) until fully paid off. You must obtain the original BPKB after completing the loan before you can sell.
- BPKB and physical vehicle match: The engine number, chassis number and plate on the BPKB must match the vehicle. Discrepancies are a serious red flag.
STNK — Vehicle Registration Certificate
The STNK (Surat Tanda Nomor Kendaraan) is the annual vehicle registration certificate — it proves the vehicle is registered and road taxes (PKB) are paid. It must be carried in the vehicle at all times and must be valid.
- Annual renewal: The STNK must be renewed annually at Samsat. Outstanding PKB (Pajak Kendaraan Bermotor — annual vehicle tax) debts must be paid before transfer.
- 5-year plate renewal: Every 5 years, the physical number plate is also renewed along with the STNK. This is a higher-cost renewal — factor this in if it is upcoming.
- Both documents together: Buyers always check both the BPKB and STNK together. A mismatch between them is an immediate red flag.
Balik nama (ownership transfer) at Samsat
The formal transfer of ownership — balik nama — changes the registered owner in both the STNK and BPKB to the buyer's name. This is done at the local Samsat (Satuan Administrasi Manunggal Satu Atap) office.
- Buyer responsibility: In Indonesian practice, balik nama is done by the buyer after purchase. However, the buyer will inspect documents and insist everything is clean before completing the sale.
- Tax implications: Balik nama involves paying BBNKB (Bea Balik Nama Kendaraan Bermotor — vehicle transfer tax), calculated as a percentage of the vehicle's assessed value. The buyer pays this.
- KIR (vehicle inspection): Required for commercial vehicles and larger vehicles — not typically required for private passenger cars sold between individuals.
Sale agreement and practical tips
- Write a kwitansi (receipt) signed by both parties — standard in Indonesian car sales.
- Some sellers and buyers also use a formal sale agreement (surat perjanjian jual beli) for additional protection.
- Check for any outstanding PKB debts and make them visible in the negotiation.
