Whether you are a solo founder deciding between an OPC and a Sole Proprietorship, a professional setting up an LLP with partners, a family starting a Partnership Firm, or a startup that needs a Private Limited Company to raise funding — the structure you choose now affects your tax, compliance, and funding options for years to come.
Karnani & Co. is a Chartered Accountant firm based in Jaipur with over 35 years of practice, handling business registration alongside tax and GST compliance so that incorporation is not a standalone transaction. Every registration is reviewed by a qualified CA, not handled entirely by an executive or filing agent.
If you already know which structure you need, use the sections below to go straight to it.
Private Limited Company Registration
A Private Limited Company is the structure investors, venture capitalists, and employees expect if you plan to raise funding, issue ESOPs, or bring in multiple shareholders. It is governed by the Companies Act, 2013, and requires a minimum of two directors and two shareholders, with liability limited to each shareholder’s investment.
Registration involves obtaining a Digital Signature Certificate (DSC) and Director Identification Number (DIN) for each director, reserving the company name, drafting the Memorandum and Articles of Association, and filing incorporation documents through the SPICe+ form with the Ministry of Corporate Affairs. Once incorporated, the company must comply with annual return filing, statutory audit requirements, and board meeting norms from the first year onward.
We register the company and set up its GST, PAN, and TAN registration alongside incorporation, so there is no gap between getting the Certificate of Incorporation and being ready to operate and invoice.
Who this is for: Startups planning to raise funding, businesses that need multiple shareholders or ESOPs, and founders who want the credibility a registered company carries with investors and larger clients.
LLP Registration in India
A Limited Liability Partnership suits professionals and businesses with two or more partners who want limited liability without the compliance load of a full company. It is governed by the LLP Act, 2008, and combines the operational flexibility of a partnership with a partner’s personal assets protected from business debts.
Compliance is lighter than a Private Limited Company. A statutory audit is required only once turnover or contribution crosses the prescribed threshold, and structural changes need far less filing with the Registrar than a company would.

Who this is for: Professionals such as CAs, architects, and consultants setting up a practice with partners, and businesses that want liability protection without company-level compliance.
Partnership Firm Registration
A Partnership Firm remains one of the simplest structures for family businesses and local trading concerns comfortable with unlimited personal liability. It is governed by the Indian Partnership Act, 1932, and formed when two or more people agree to run a business together and share profits as defined in a Partnership Deed.
Registration is technically optional but strongly recommended, since an unregistered firm cannot sue a third party or enforce a contract in court. We draft the partnership deed, register the firm, and handle PAN and GST registration together so the firm can start invoicing immediately.

Who this is for: Family businesses and local traders who want a simple, low-cost structure and are comfortable with unlimited liability.
One Person Company (OPC) Registration
A One Person Company lets a solo founder operate with limited liability and a corporate identity, without needing a co-founder. It requires only one member, who is also typically the sole director, along with one mandatory nominee director appointed at incorporation to ensure continuity if the founder becomes incapacitated.
Any Indian resident individual can register an OPC as its sole member, provided they are not already a member of another OPC. Registration follows the same DSC, DIN, and SPICe+ filing steps as a Private Limited Company, but with a simpler shareholding structure.
An OPC does have limits worth knowing before you register. It cannot bring in additional shareholders without converting to a Private Limited Company, and it must convert once it crosses prescribed turnover or paid-up capital thresholds.
Who this is for: Solo founders who want limited liability and a corporate identity but have no immediate plans to bring in co-founders or outside investors.
Sole Proprietorship Registration
A Sole Proprietorship is the fastest way to start operating, suited to freelancers and small local businesses testing an idea before committing to a heavier structure. There is no separate legal entity — the business and the owner are legally the same, and the owner carries unlimited personal liability for business debts.
We help with GST registration, MSME (Udyam) registration, and the basic registrations needed to open a current bank account and start invoicing. We also flag upfront where the unlimited liability could become a real risk as the business grows, so you are not caught by surprise later.
Who this is for: Freelancers and small business owners who want to start quickly and keep compliance minimal, and are comfortable with unlimited personal liability at this stage.
Startup India Recognition
Eligible new businesses can apply for DPIIT recognition under the Startup India scheme to access tax exemptions, easier compliance, and other benefits designed for early-stage companies. Recognition is separate from incorporation and is applied for after the entity, typically a Private Limited Company or LLP, is already registered.

Who this is for: Newly incorporated companies and LLPs that meet the Startup India eligibility criteria and want the associated tax and compliance benefits.
Choosing Between OPC and Private Limited Company
This is the most common decision point for solo founders, and there is no single right answer for everyone.
An OPC suits a solo founder who wants limited liability and a corporate identity but has no immediate plans to bring in co-founders or outside investors, since it needs only one member and carries fewer compliance obligations than a full company. A Private Limited Company becomes the better choice the moment funding, ESOPs, or multiple shareholders enter the picture, since an OPC cannot accommodate additional shareholders without converting first.
If you are certain you will need external funding within a year or two, registering directly as a Private Limited Company usually saves the cost and delay of a later conversion.
Who this is for: Solo founders trying to decide between the two structures before they register.

Frequently Asked Questions
How much does it cost to register a business in India?
Government fees depend on the structure you choose, the authorised capital, and the state of registration, and typically range from a few thousand rupees for a Partnership Firm or Sole Proprietorship to a higher amount for a Private Limited Company or LLP. Professional fees are quoted separately after we understand your specific requirement. Contact us for an itemised estimate before you proceed.
Which is better, OPC or Private Limited Company?
An OPC suits a solo founder with no immediate plans for co-founders or outside funding, since it needs only one member and carries a lighter compliance load. A Private Limited Company is the better choice once you plan to raise funding, issue ESOPs, or bring in multiple shareholders, since an OPC cannot accommodate additional shareholders without conversion.
How do I register a small business in India?
The right structure depends on your liability tolerance, number of founders, and growth plans, ranging from a Sole Proprietorship for a solo, low-risk venture to an LLP or Private Limited Company for a business with partners or funding ambitions. We recommend a short consultation before you file anything, since the structure you pick affects your tax position and compliance load for years afterward.
What are the disadvantages of an OPC?
An OPC is limited to one member and cannot bring in additional shareholders without converting to a different structure. It must mandatorily convert to a Private Limited Company once it crosses prescribed turnover or paid-up capital thresholds, and it is not suited to businesses that plan to raise equity funding from investors.
Who is eligible to register an OPC?
Any Indian resident individual can register an OPC as the sole member, provided they are not already a member of another OPC. A nominee director must also be appointed at the time of incorporation to take over in case the sole member becomes incapacitated or passes away.
Can I register an OPC myself, without a consultant?
Technically yes, since the MCA portal allows self-filing, but the process involves DSC and DIN generation, drafting the MOA and AOA correctly, and SPICe+ filing, where errors commonly cause rejections and delays. Most founders find it faster and less error-prone to have a professional handle the filing while they focus on the business.
Is GST registration mandatory for an OPC?
GST registration is mandatory for an OPC once its turnover crosses the prescribed threshold for its category of business, or if it is engaged in specific categories of supply where registration is compulsory regardless of turnover. We assess this as part of the registration process so GST compliance starts on time rather than being missed.
What is the minimum number of directors required in an OPC?
An OPC requires only one director, who is also typically the sole shareholder, along with one mandatory nominee director named at incorporation. This is one of the key differences from a Private Limited Company, which requires a minimum of two directors.
