Before you start

An assessment of your tax residency under both the day-count and intent tests
An NPWP registered at the KPP covering your address — city, Sleman or Bantul are different offices
For any property transaction: an independent Indonesian notary/PPAT, not one introduced by the seller or the agent
A land certificate check at the local land office (BPN) confirming the title type and, in this province, whether the land is Sultan Ground or Pakualaman Ground

Step-by-step

1
Work out when you became a tax resident
More than 183 days in Indonesia in any rolling twelve-month period makes you resident, and the days need not be consecutive. So does being present with the intention to reside, evidenced by a long stay permit, an employment contract or a long lease. A one-year study or work permit plus a year's rent paid up front is exactly that evidence.

2
Register for an NPWP at the right office and file annually
Register with passport and KITAS at the KPP covering your address, or online through DJP. Residents use the sixteen-digit NIK format. File the annual SPT by 31 March through Coretax, reconciling withheld tax, reporting worldwide income and claiming any treaty relief. Without an NPWP, withholding on Indonesian employment income runs at a penalty rate.

3
Understand what a foreigner may actually hold, before anyone shows you a house
Article 21 of the Basic Agrarian Law reserves Hak Milik freehold to Indonesian citizens. A foreigner with a valid stay permit may hold Hak Pakai — a right of use, granted under Government Regulation 18/2021 for up to 30 years, extendable by up to 20 and renewable for up to 30, so up to 80 years in total — and may hold strata title on an apartment. Both are subject to national minimum purchase prices set by ministerial decision: in the Special Region of Yogyakarta these are IDR 5 billion for a landed house and IDR 2 billion for an apartment unit. Below those figures a foreigner simply may not buy.

Check the land office record for Sultan Ground or Pakualaman Ground
Under the province's special-status law the Sultanate and the Pakualaman are legal entities that hold land, and a great deal of the city and the surrounding villages sits on it. Occupation of such land runs on a palace-issued permit — a serat kekancingan — which is a permission with a term, not a transferable title. What is presented as a house sale on such land is a sale of the building and a hoped-for transfer of the permit. Establish the status at the land office before money moves.

Pay the transaction and holding taxes to the right regency
Acquisition duty on a property purchase and annual land and building tax are both regional, assessed by the city or regency the property sits in. Yogyakarta city, Sleman and Bantul are three separate authorities with their own rates and their own assessed values. Confirm which applies before you budget, because the built-up area does not follow the boundary.

Things most newcomers don’t know

The nominee arrangement is not a grey area: Article 26(2) of the Basic Agrarian Law voids it and the money is not recoverable.

Every version of the structure — buying in an Indonesian friend's or spouse's name with a side agreement — is a transaction intended to transfer freehold to a foreigner. The statute says such transactions are void by law, the land falls to the state, and the payments made cannot be reclaimed. That last clause is the part nobody quotes: you lose the land and the purchase price. Notaries who draw these agreements are not making them valid, and enforcement of exactly this structure has been tightening.

The 1975 instruction bars freehold to Indonesian citizens of non-indigenous descent, and it is contested rather than settled.

Instruction K.898/I/A/1975 of the deputy head of the region, dated 5 March 1975, directs that Hak Milik not be granted to Indonesian citizens of non-indigenous descent, who receive Hak Guna Bangunan or Hak Pakai instead. The Ombudsman RI found maladministration and recommended in July 2020 that it cease to be applied; the land offices have continued to apply it, and challenges at the Supreme Court and the administrative courts have not dislodged it. It binds Indonesian citizens, not foreigners — no foreigner may hold Hak Milik anywhere in Indonesia in any event — so read it as context for how this province's land market actually behaves rather than as a rule that applies to you. Take advice on the current position rather than assuming either that it is dead or that it is settled.

The minimum purchase prices for foreigners exceed almost everything on the Yogyakarta market.

Ministerial Decision 1241/2022 sets the floors: IDR 5 billion for a landed house and IDR 2 billion for an apartment in this province. Yogyakarta is the cheapest of Java's major cities, so very little stock clears those thresholds — which means the honest answer for most foreigners here is that there is nothing they may lawfully buy, and the sensible structure is a long lease. Anyone offering a route around the floor is offering a nominee arrangement by another name.

Sultan Ground is occupied by permit, and the permit is not a deed.

Law 13/2012 recognises the Sultanate and the Pakualaman as legal entities holding land, and Perdais 1/2017 governs its management and use. Occupation runs on a serat kekancingan issued by the palace, for a term and for a stated purpose. It cannot be mortgaged, and its renewal is not yours to control. Buildings on such land change hands informally all the time, which is precisely why a land office check before any payment is not optional here.

Common mistakes to avoid

Buying through an Indonesian nominee — the transaction is void by law, the land goes to the state, and the money is not recoverable.
Assuming a national property guide covers Yogyakarta, when Sultan Ground and the 1975 instruction have no national equivalent.
Using the seller's or agent's notary rather than an independent PPAT who works for you.
Paying anything before a land office check confirms the title type and whether the land is Sultan Ground or Pakualaman Ground.
Letting a stay permit lapse while holding Hak Pakai, since the property right depends on the permit remaining valid.
