Partnership Business Registration in Sri Lanka: A Guide for 2026

Going into business with someone else changes more than just the workload. It changes how the business is owned, how profits are split, and importantly, how much personal risk each person is taking on. For many small business owners in Sri Lanka, from two friends opening a shop to family members starting a service business together, a partnership is the natural next step up from working solo.

But a partnership isn’t just a sole proprietorship with more people attached. It comes with its own registration process, its own tax treatment, and a legal principle, joint and several liability, that every partner needs to understand before signing anything.

In this guide, you’ll learn how to do your partnership business registration in Sri Lanka step by step, including the documents you need, how registration fees and taxes work, what a partnership agreement should cover, and what happens if a partner leaves, joins, or the business needs to be wound up. 

So, read on to register your partnership the right way and go in with a clear picture of what you’re taking on. 

What Is a Partnership Business in Sri Lanka?

A partnership is a business owned and run by two or more people who agree to share the capital, work, and profits. It’s governed by the Partnership Ordinance No. 21 of 1866, one of the oldest pieces of business legislation still in force in Sri Lanka.

Like a sole proprietorship, a partnership is not a separate legal entity. The business and the partners are legally the same thing. This means every partner carries personal liability for the partnership’s debts, not just up to their share of ownership, but potentially the full amount (more on this later).

This structure suits people who want to go into business with someone else, pool resources, and split responsibilities, without the cost and paperwork of incorporating a Private Limited Company.  

Requirements to Start a Partnership Business in Sri Lanka:

• At least two partners: There’s no fixed legal maximum, but larger groups often outgrow the partnership structure and move toward incorporation.
• All partners must be Sri Lankan citizens or permanent residents. Foreign nationals cannot register as partners.
• A physical registered business address in the area covered by your local Divisional Secretariat.
• A partnership agreement setting out how the business will run (not legally mandatory, but strongly recommended, covered next). 

Partnership vs. Sole Proprietorship vs. Pvt Ltd: Where Does It Fit?

If you’re still deciding on a structure, here’s how a partnership compares to the other two options.

Factor	Partnership	Sole Proprietorship	Private Limited (Pvt Ltd)
Legal identity	Same as the partners	Same as the owner	Separate legal entity
Liability	Personal, joint and several	Unlimited personal liability	Limited to company assets
Registration	In person, Divisional Secretariat	In person, Divisional Secretariat	Online, eROC
Taxation	6% partnership tax, then allocated to partners’ personal income	Taxed as personal income	Separate company tax
Foreign ownership	Not allowed	Not allowed	Up to 100% in most sectors
Credibility	Moderate	Lower	Higher
Continuity	Depends on the agreement	Ends with the owner	Continues beyond ownership changes

A partnership sits between the two other structures. It gives you more capacity than a sole proprietorship, since you can pool capital and split the workload with someone else, but it doesn’t offer the liability protection or formality of a Pvt Ltd company. Every partner remains personally on the hook for the business’s debts, regardless of their ownership share.

In practice, a partnership makes the most sense when two or more people want to run a business together, are comfortable sharing that liability, and don’t yet need the cost or complexity of incorporating. It’s a step up from going solo, but a step below forming a company.

Note:

If you’re starting out alone, our Individual Business Registration guidecovers the sole proprietorship process in full.

Or, if you’re looking to bring in outside investors, limit personal liability, or work with foreign shareholders, our Business Registration guide walks through incorporating a Pvt Ltd company instead. 

Do I Need a Partnership Agreement (Deed)?

Legally, no. Under the Partnership Ordinance, a partnership can be formed with nothing more than a verbal or implied agreement between the partners, and it’s still enforceable in law. There’s no requirement to submit a written agreement to register your business at the Divisional Secretariat.

That said, going without one is one of the riskiest shortcuts a new partnership can take.

Why Is It Recommended to Have a Partnership Agreement (Deed)?

Without a written agreement, disputes between partners fall back on the default rules of the Partnership Ordinance, which may not reflect what any of you actually intended. A written agreement protects everyone by putting expectations on record before problems arise, not after.

It also gives you a clear reference point if a partner wants to leave, a new partner wants to join, or the business needs to be wound up. Without one, these situations tend to become slower, more expensive, and more likely to end in dispute.

Because of how much rests on it, it’s worth having a lawyer draft or review the agreement rather than using a generic template.

A Solid Partnership Agreement Should Set Out:

• Capital contribution: how much each partner is putting in, and in what form (cash, assets, property).
• Profit and loss split: how earnings and losses are divided, which doesn’t have to match capital contribution.
• Roles and responsibilities: who manages what day to day.
• Decision-making: how major business decisions get approved.
• Admission of new partners: the process and consent required to bring someone else in.
• Exit of a partner: what happens if someone wants to leave, retire, or sell their share.
• Dispute resolution: how disagreements between partners get settled.
• Dissolution terms: what triggers winding up the partnership, and how remaining assets and debts are handled.

A partnership agreement won’t stop disagreements from happening, but it decides how they get resolved before emotions are involved. Treat it as a founding document, not paperwork to get to later. The best time to agree on these terms is before there’s any money, property, or conflict on the table.   

What Are the Documents You Need to Submit for Partnership Business Registration in Sri Lanka?

Gathering everything before you visit the Divisional Secretariat will save you a return trip. Here’s what every partner needs to prepare.

1. NIC or passport copies: Every partner must provide a clear copy of their National Identity Card. Since foreign nationals cannot register as partners, a passport is only relevant if a partner is a Sri Lankan citizen residing overseas.

2. Grama Niladhari report: A certified report from the Grama Niladhari of the area where the business operates, confirming the business and its location. This must be countersigned by the Divisional Secretary.

3. Proof of business premises: This depends on how the property is held:

• A certified copy of the deed if the premises are owned by a partner
• A rent or lease agreement if the premises are rented
• A consent letter from the owner, plus their NIC copy, if the premises belong to a family member

4. Trade permit: If required for your business type, obtain this from the relevant municipal or divisional council.

5. Partnership agreement: While not legally mandatory, submitting your written agreement alongside the application helps establish the terms on record from day one.

6. Affidavit and Declaration Statement: Each partner must sign a separate affidavit and declaration confirming the details in the application. These are signed individually, in each partner’s own name, not on behalf of the partnership.

7. Sector-specific approvals: Certain regulated industries require additional clearance before the Divisional Secretariat will process your registration. For example:

• Food-related businesses need approval from the Public Health Inspector
• Pharmacies need certification from the Sri Lanka Medical Council
• Guest houses and spas need reports from the local police division
• Ayurvedic practices, nurseries, and vocational service providers each fall under their own sector-specific approving authority

Check with your local Divisional Secretariat to confirm which, if any, apply to your partnership.

Missing any one of these documents typically means resubmitting your application, so it’s worth double-checking the full list before your visit. 

How to Do Your Partnership Business Registration: Step-by-Step Guide for 2026

Registering a partnership is an in-person process, handled entirely through your local Divisional Secretariat. There’s no online option, unlike company registration through eROC. Here’s how it works, step by step.

• Step 1: Get Form BNR-03. Visit the Divisional Secretariat covering your business location and request the application for registration of a business name of a partnership business. This is a different form from the BNR-01 used for sole proprietorships, so make sure you ask for the right one.
• Step 2: Complete the form with all partners’ details. This includes each partner’s full name, date of birth, place of residence, contact details, and signature, along with the business name, principal place of business, date of commencement, and initial capital.
• Step 3: Each partner signs a separate affidavit and declaration. These confirm the details in the application and must be signed individually by each partner, not collectively as the partnership.
• Step 4: Gather your supporting documents. NIC copies, proof of premises, trade permit if required, and any sector-specific approvals. See the documents section above for the full list.
• Step 5: Get your Grama Niladhari report. This certifies the business and premises details and must be countersigned by the Divisional Secretary.
• Step 6: Submit everything and pay the registration fee at the Divisional Secretariat office.
• Step 7: Receive your Certificate of Registration. Once approved, this must be displayed at your business premises, just as with a sole proprietorship.

Important Note

Your business name must be registered within 14 days of commencing operations, extendable to a ceiling of 30 days in some cases. Don’t wait until the business is already running to start this process.

Once submitted with all documents in order, registration typically takes 7 to 14 working days.

Do I Have to Pay Registration Fees for This Arrangement?

Yes. There’s no fixed nationwide rate for partnership registration. The fee depends on your local Divisional Secretariat and the capital you declare on your application, so amounts can vary from one office to another. It’s best to call or visit your relevant office ahead of time to confirm the exact figure, so there are no surprises on the day you submit. 

How Partnerships Are Taxed?

Partnership income isn’t taxed quite like a sole proprietorship’s, and understanding this upfront helps you plan cash flow correctly from year one.

A partnership pays a flat 6% tax on its income once that income exceeds Rs. 1 million. This is a tax on the partnership itself, calculated before profits are split between partners.

Once that 6% is paid, the remaining profit is allocated to each partner according to their agreed ownership share. That share is then added to each partner’s other personal income, if any, and taxed at Sri Lanka’s prevailing personal income tax rates, which range from 6% to 36% depending on total income.

To avoid double taxation, partners can claim a credit for the 6% partnership tax already paid, offsetting it against their personal income tax liability on that same share of profit.

This is worth flagging because it differs from how a sole proprietorship is taxed. As a sole trader, your business income is treated entirely as personal income, and you’re entitled to an annual tax-free relief of Rs. 1.8 million before any tax applies. A partner doesn’t get that same flat individual relief on their share of partnership income in the same way, since the partnership-level tax applies first.

Furthermore, VAT registration works the same way it does for other business structures. If your partnership’s turnover exceeds the current VAT threshold, you’re required to register and charge VAT on taxable sales.

Given how the 6% partnership tax, personal tax credit, and VAT threshold interact, it’s worth speaking to a tax advisor early, particularly if partners have significant income from other sources, since that can affect how much benefit the tax credit actually delivers at an individual level. 

What is Meant by Joint and Several in Partnership Business Aspect in Sri Lanka

“Joint and several liability” is the legal principle behind how partnership debt works in Sri Lanka, and it’s the single biggest risk of this business structure. 

Under the Partnership Ordinance, every partner is liable for the full debts of the partnership, not just a portion matching their ownership share. “Joint” liability means all partners can be held responsible together. “Several” liability means a creditor can also pursue any one partner individually for the entire outstanding amount, regardless of what that partner actually owns or how much of the debt they personally caused.

Why Does This Matter for Partners?

It removes the protection that ownership percentage might suggest you have. A 20% partner can end up personally covering 100% of a debt if the other partners can’t pay, and can only try to recover that money from them afterward, which is often difficult in practice.

What Are the Practical Risks?

The exposure goes beyond business decisions gone wrong. If one partner signs a bad contract, takes on debt without informing the others, or simply makes a poor call, every partner shares the liability. It also works the other way: if a partner has personal debts or a creditor comes after them individually, that creditor may be able to reach partnership assets to satisfy it, even if the rest of the partners had nothing to do with it.

How Do You Protect Yourself Against This?

This is exactly why a solid written partnership agreement matters so much. While it can’t override the legal principle of joint and several liability toward outside creditors, it can set clear terms for how partners resolve disputes and recover losses from each other internally.

If your risk tolerance is low, or you’re going into business with people whose financial habits you can’t fully vouch for, this is often the point where a Private Limited Company becomes the safer structure instead. 

What Happens If a Partner Leaves, Dies, or a New Partner Joins? 

This section only applies if your partnership agreement includes a continuity clause. Without one, any of these events can dissolve the partnership entirely, covered in the next section.

• If a Partner Leaves: A partner can retire or sell their share voluntarily. The remaining partners typically buy out the exiting partner’s stake or reallocate it among themselves, based on terms set in the agreement. The exiting partner isn’t automatically released from liability for debts incurred while they were still a partner.
• If a Partner Dies: If the agreement provides for continuity, the surviving partners can carry on the business rather than winding it up. The deceased partner’s share usually passes to their estate, and the agreement should set out how that share is valued and settled with the heirs.
• If You Want to Add a New Partner: Bringing in a new partner requires consent from the existing partners and an updated written agreement reflecting the new capital contribution, profit share, and role. The new partner should also sign their own affidavit and declaration.

Important note:

Whenever partner details change, whether someone joins, exits, or the business address changes, you need to notify your Divisional Secretariat and update your registration accordingly. Delaying this can create mismatches between your official records and who’s actually running the business. 

How to Dissolve a Partnership Business in Sri Lanka

There are a few general pathways that lead to a partnership being dissolved. They are as follows:

1. Default dissolution: Without a continuity clause in the agreement, a partnership dissolves automatically the moment any single partner dies, withdraws, retires, or becomes bankrupt. This is the default position under the Partnership Ordinance. It applies to the entire partnership, not just the affected partner’s share.
2. Voluntary dissolution: Partners can also choose to end the partnership by mutual agreement. This is typically done by following the notice period and process set out in the partnership agreement, giving everyone a clear, pre-agreed way to wind things down.
3. Dissolution by the agreed term or purpose: Some partnerships are formed for a fixed period or a specific project rather than an open-ended business. In these cases, the partnership dissolves automatically once that term ends or the purpose is fulfilled. Partners can choose to continue the business, but doing so usually means renewing or updating the agreement.
4. Court-ordered dissolution: In cases of serious dispute, misconduct, or a partner unable to fulfil their obligations, a court can order the partnership to be dissolved.

Things You Have to Do When Winding Up Your Partnership Bussiness

Once dissolution is triggered, you need to:

• Settle outstanding debts before distributing any remaining assets. Creditors are paid first.
• Distribute remaining assets among the partners according to their agreed shares in the partnership agreement.
• Finalise accounts, including any outstanding tax filings for the partnership and its partners.
• Deregister the business with your Divisional Secretariat once winding up is complete.
• Notify relevant parties, including banks, landlords, and any regulatory bodies tied to sector-specific approvals your business held.

This is a more informal process than closing a Pvt Ltd company, which involves formally striking off the company with the Registrar of Companies and settling any outstanding annual return obligations. 

Common Mistakes to Avoid When You’re Partnering Up for a Business

Even a simple structure like a partnership can run into trouble if a few basics get overlooked early on. Here’s what to watch out for.

1. Operating without a written agreement: Verbal agreements are legally enforceable, but they leave far too much open to interpretation once real money and disagreements are involved. Put the terms in writing before you start operating, not after a dispute forces the issue.
2. Not filing separate affidavits per partner: Each partner needs to sign their own affidavit and declaration individually. Submitting a single joint statement or missing one partner’s signature is a common reason applications get sent back.
3. Missing the 14-day registration window: Many partners start operating before registering, assuming they can formalise things later. The Ordinance requires registration within 14 days of commencing business, extendable to a 30-day ceiling. Waiting longer than that puts you out of compliance from day one.
4. Assuming profit share equals liability share: A partner who owns 20% of the business can still be personally liable for 100% of the partnership’s debts. Don’t mistake your ownership percentage for a cap on your financial exposure.
5. Not planning for a partner’s exit or death upfront: Without a continuity clause in the agreement, one partner leaving or passing away can dissolve the entire partnership, even if the remaining partners want to keep going. Address this in the agreement from the start, not when it actually happens.
6. Skipping sector-specific approvals: If your business falls under a regulated industry, registering the partnership name alone isn’t enough to operate legally. Confirm what additional approvals apply to you before you open your doors. 

Can Foreigners Join a Partnership?

No. Only Sri Lankan citizens and permanent residents can register as partners in a partnership business. This holds true even if a foreign national holds a valid visa or temporary residency in Sri Lanka.

This is the same restriction that applies to sole proprietorships, since neither structure is a separate legal entity from its owners. A foreign national who wants to go into business in Sri Lanka, whether alone or with others, cannot do so through a partnership or sole proprietorship.

If you’re a foreign investor looking to start a business with local or international partners, incorporating a Private Limited Company is the path available to you instead. A Pvt Ltd company allows up to 100% foreign ownership in most sectors, and is registered entirely online through the eROC portal rather than in person at a Divisional Secretariat. 

Conclusion

Registering a partnership in Sri Lanka is a straightforward, in-person process, but the real work happens before you ever visit the Divisional Secretariat. Getting the partnership agreement right, understanding how joint and several liability exposes every partner personally, and knowing how partnership income is taxed all matter far more than the paperwork itself.

If you take one thing from this guide, let it be this: a written partnership agreement isn’t optional in practice, even if it’s optional in law. It’s what decides how disputes, exits, and even dissolution play out, long before any of those things actually happen.

From there, the process is simple. Gather your documents, complete Form BNR-03, get each partner’s affidavit signed, and submit everything to your local Divisional Secretariat within 14 days of starting operations.

Go in with the agreement settled, the liability understood, and the tax treatment planned for, and your partnership starts on solid ground instead of catching up to problems later.
