Key takeaways
- A sole proprietorship (usaha perseorangan) is a business owned and run by one person, with no legal line between owner and business. You keep all the profit and you’re personally liable for every business debt.
- You register for a free business identification number (NIB) online and use your national ID number (NIK) as your tax number (NPWP). A notarial deed is common practice, but the law doesn’t require one.
- If your turnover stays at or below Rp4.8 billion a year, you can pay a 0.5% final tax on turnover with no time limit. The first Rp500 million of turnover each year is tax-free for individuals.
- A PT Perorangan gives Indonesian citizens aged 17 or over limited liability through a simple online set-up. It’s worth comparing as your turnover and business risks grow.
What is a sole proprietorship?
A sole proprietorship is a business owned and run by one person, with no legal separation between the owner and the business. In Indonesia it’s called usaha perseorangan, and many owners trade under a usaha dagang (UD) name.
Because you and the business are legally the same, its earnings and debts are yours. Picture a batik seller trading as UD Batik Sari: the name appears on invoices, but every contract sits in the owner’s name.
Key features of a sole proprietorship
A few legal traits set a sole proprietorship apart from other structures. They shape how you’re taxed and how much risk you carry.
- One owner holds 100% of the business and makes every decision
- The business has no legal identity separate from its owner
- The owner carries unlimited personal liability for business debts
- Business earnings are taxed through the owner’s personal income tax (Pajak Penghasilan, or PPh)
Advantages of a sole proprietorship
A sole proprietorship keeps set-up costs and paperwork low, so you can start trading quickly. These are the main benefits.
- You can get your NIB free of charge through the Online Single Submission (OSS) system
- You can pay a 0.5% final tax on turnover, with the first Rp500 million each year tax-free
- You keep every rupiah of profit after tax and make all decisions yourself
- You report business earnings on your own annual tax return
- You can start a UD without a notarial deed, though many owners still choose one
Disadvantages of a sole proprietorship
The simplicity that makes a sole proprietorship easy to start also places all the risk on you. Weigh these trade-offs first.
- Your personal assets, such as your home and savings, can be used to pay business debts
- Your profit can reach the top personal income tax rate of 35% if you’re taxed at progressive rates
- Your earnings depend on you working, so illness or time off can pause the business
- Your business can have only one owner, so taking on partners or investors means changing structure
Sole proprietorship tax obligations in Indonesia
As a sole proprietor, you pay tax as an individual under rules set by the Directorate General of Taxes (DJP). Here’s what applies for the 2026 tax year.
Tax registration with your NIK
Your NIK now doubles as your NPWP. Since 1 January 2025, individuals activate their NIK as an NPWP through Coretax DJP, the DJP’s new tax administration system.
Personal income tax rates
If you pay tax on profit, progressive PPh rates under the Tax Harmonisation Law (UU HPP) apply after your tax-free allowance (PTKP). The PTKP is Rp54 million for a single person, plus Rp4.5 million each for a spouse and up to three dependants.
Each band of taxable income has its own rate:
- 5% on the first Rp60 million
- 15% above Rp60 million up to Rp250 million
- 25% above Rp250 million up to Rp500 million
- 30% above Rp500 million up to Rp5 billion
- 35% above Rp5 billion
The 0.5% final tax for small businesses
With turnover of Rp4.8 billion a year or less, you can instead pay 0.5% of gross turnover under Government Regulation (PP) 20/2026. Since 22 April 2026, individuals can use this rate with no time limit while they qualify.
The first Rp500 million of turnover each year stays tax-free for individuals. Say your catering business turns over Rp800 million: you’d pay 0.5% on Rp300 million, or Rp1.5 million, with no cost deductions.
Choosing between bookkeeping and NPPN
At progressive rates, you work out profit from full books (pembukuan) or the net income calculation norm (NPPN). NPPN is open below Rp4.8 billion turnover if you notify the DJP within the tax year’s first three months; otherwise, full bookkeeping applies.
VAT registration
Once turnover exceeds Rp4.8 billion a year, you must register as a VAT-registered business (PKP) and charge value added tax (PPN). The PPN rate is 12% from 1 January 2025, but most goods and services are taxed on 11/12 of the price.
That keeps the effective rate at 11% for everything except luxury items.
Annual returns and records
Your annual individual tax return (SPT Tahunan) is due by 31 March, and late filing brings a Rp100,000 fine. The General Tax Provisions Law (UU KUP) requires you to keep books and records in Indonesia for 10 years.
How to set up a sole proprietorship in Indonesia
Setting up a sole proprietorship in Indonesia takes six steps, and you can complete most of them online. Work through them in order.
1. Activate your NIK as your NPWP
Log in to Coretax DJP and activate your NIK as your tax number. You’ll use it for every tax payment and return.
2. Choose a business name and KBLI code
Pick a trading name, such as UD plus your chosen name. Then find the Indonesian standard business classification (KBLI) code for your activity, using the KBLI 2025 list.
3. Register for an NIB through OSS
Create an OSS account and apply for your NIB using your KBLI code. Licensing is risk-based under PP 28/2025, which replaced PP 5/2021.
4. Check whether you need extra permits
OSS assesses the risk level of each business activity. Higher-risk activities may need permits on top of the NIB, so check your result before trading.
5. Separate your business finances
Open a bank account just for the business, even though the law treats your money as one pot. Recording every sale and expense from day one makes tax time quicker.
6. Register for BPJS Ketenagakerjaan
If you’re self-employed, you can join the BPJS Ketenagakerjaan social security scheme as a non-wage earner (BPU), subject to its age limit for new members. You can register online for work accident, death and old-age savings cover.
Sole proprietorship vs PT Perorangan
A PT Perorangan is a one-person limited liability company, and it’s the closest Indonesian alternative to a sole proprietorship. Here’s how the two compare.
- A sole proprietorship has no separate legal identity, while a PT Perorangan is a legal entity in its own right
- A sole proprietor’s personal assets back every business debt, while a PT Perorangan gives its founder limited liability
- A UD registers through OSS, while a PT Perorangan files an online statement of establishment through the AHU legal administration system, without a notarial deed
- A PT Perorangan founder must be a legally capable Indonesian citizen aged 17 or over, and can set up only one a year
- A sole proprietor and a PT Perorangan can both use the 0.5% final tax, but only individuals get the Rp500 million tax-free portion
Is a sole proprietorship right for your business?
A sole proprietorship suits you best when your risks are low and you want to start trading quickly. It tends to fit if you:
- work alone or with a small team
- expect turnover within the Rp4.8 billion final tax limit
- face a low risk of large claims or debts
- want a simple set-up with light ongoing admin
A PT Perorangan is worth a look when contracts or borrowing expose you to bigger debts. It’s open to Indonesian citizens whose business meets micro or small business criteria, and a tax adviser can compare the options.
Legal considerations and insurance
Contracts and debts sit in your name, so any claim falls on you personally. Read liability clauses closely, and update your NIB details and permits whenever your activities change.
Business insurance, such as property or liability cover, protects your equipment and covers customer claims. It adds to your personal BPJS cover, and a broker can match a policy to your activity.

FAQs on sole proprietorship
These answers cover common questions about running a sole proprietorship in Indonesia.
Is a sole proprietor 100% the owner of the business?
Yes, you own the whole business and keep all its profit after tax. Adding a co-owner means moving to a different structure.
What happens to my personal assets as a sole proprietor?
Your savings and property can be claimed to pay business debts, because the law treats you and the business as one. A separate bank account keeps your books clean, while limited liability comes only from a legal entity such as a PT Perorangan.
Can a foreigner set up a sole proprietorship in Indonesia?
A PT Perorangan is reserved for Indonesian citizens, so foreign nationals can’t found one. Foreign investors generally set up a foreign investment company (PT Penanaman Modal Asing, or PT PMA), so get local legal advice first.
Can I switch from a sole proprietorship to a PT Perorangan later?
Yes, you can set up a PT Perorangan through AHU once you meet the eligibility criteria. The company receives its own NPWP, so its tax is reported separately from yours.
Can a sole proprietorship have employees?
Yes, you can hire staff. Employer obligations fall on you personally, so check payroll and BPJS requirements before your first hire.
What happens to a sole proprietorship if the owner stops trading or dies?
The business ends when you stop trading, and its assets and debts stay with you or pass to your estate. A PT Perorangan continues as its own legal entity.
