Kost (kos, kos-kosan, indekos) in Indonesia
Kost (also kos, kos-kosan or indekos) is Indonesia's standard monthly room rental: a furnished or bare room in a house or small building, rented to students and workers. Rooms are often single-sex: kost putra (men), kost putri (women) or kost campur (mixed). A growing number of companies now manage kost for owners.

Key figures
- Mamikos says it lists 2 million+ kost rooms in 140+ cities (its own About page). [source, 21 Oct 2026]
- Singgahsini, Mamikos's management arm, manages 20,000+ kost rooms (Warta Ekonomi, Apr 2025). [source, Apr 2025]
Rules
- Kos is a taxable "hotel services" object under the regional goods-and-services tax (PBJT), Article 53(1)(j) of Law 1/2022 (UU HKPD). The old Law 28/2009 floor of more than 10 rooms no longer applies, so even one unit can be taxed. Each region sets the rate in a local regulation, up to 10% (Ministry of Finance, reported by DDTC News, 14 Sep 2024). [source, 14 Sep 2024]
