Chennai is the main city of Tamil Nadu and is also one of the largest Business Hubs located in southern India, and every year, thousands of people travel to the city for new start-up businesses, family-owned companies, and established freelancers; some of which will form a new limited company and others that have already formed will need to form another layer as part of creating a new limited company; choosing the right company structure is one of the most critical parts of setting up a business.
Choosing the appropriate way to register your business will determine how you will operate your business legally, how you will be taxed, how much money you will raise through funders, how and who will have an interest in your business, and the long-term prospects of a successful business.
Partnership vs Proprietorship vs Company Registration in Chennai
1. Sole Proprietorship
The most common type of business in India is a sole proprietorship or “one-man” business. In addition to being the simplest of the various forms of businesses operating in India today, a sole proprietorship also has some unique characteristics. The owner typically does not have a separate legal entity from the business; the business is owned and operated by a single person. This means that all business profits belong to the owner and all business losses belong to the owner (including any liabilities arising from the business).
Also, the sole proprietor has unlimited liability for all debts incurred by the business. Therefore, if the business fails, the sole proprietor will have to repay any loans or debts, whether or not there is enough money in the business to do so.
In addition to these features of sole proprietorships, there are some additional advantages: the owner has complete control over the business; the owner can operate the business with very few formalities, since there are few registration requirements if the business is located in Chennai; and the owner can frequently withdraw excess funds from the business for personal use.
Although there are no formal requirements for registering as a sole proprietor in Chennai under the Companies Act, there are some types of registrations that the owner may want to consider:
1) Registering as a sole proprietor under the Tamil Nadu Shops and Establishments Act with the appropriate local labour department/chennai municipal authority;
2) Registering online as a micro/small/medium enterprise (Udyam) using the Ministry of MSME’s website to receive a user ID and password.
3) If the owner will sell goods or provide services in excess of ₹40 lakhs (₹20 lakhs for services), the owner must also register for the Goods and Services Tax (GST) with the appropriate local GST office.
2. Partnership Business
A partnership business is one that has more than one owner who both contribute capital and agree to share the profits or losses. A partnership business operates under the provisions of the Indian Partnership Act of 1932.
The key elements of a partnership are:
- There are multiple owners, with a maximum of 50 partners (two or more);
- They will have joint responsibility to manage the business;
- A written Partnership Deed is required outlining each partner’s capital contributions, profit share percentage, and duties and responsibilities;
- All partners will have unlimited liability for the full amount of the business’s debts;
- As is the case with a proprietorship, the partnership business does not have a separate legal entity from the partners in the partnership;
- Fewer compliance requirements than for a company.
How to register a partnership firm in Chennai?
- While registration is not compulsory, it is highly recommended for legal benefits in the event of a dispute between the partners.
- The registration process involves preparing a Partnership Deed that outlines each partner’s capital contributions, the profit-sharing ratio, the partners’ duties, and the method for resolving disputes.
- To register a partnership, the registration must be completed online via the Tamil Nadu Registrar of Firms website.
3. Private Limited Company
A Private Limited Company is a legal identity formed and registered in accordance with the Companies Act, 2013, under the oversight of the Ministry of Corporate Affairs.
The following are the most common features of Private Limited Companies:
- Separate legal identity: A Private Limited Company is a separate legal entity distinct from its owners.
- Limited liability protection: The liability of the company’s shareholders is limited to each shareholder’s share capital investment in the company.
- Perpetual existence: A Private Limited Company does not cease to exist due to changes in the company’s shareholders.
- Investment-friendly: Private limited companies find it easier to raise funds from investors, venture capitalists, and angel investors.
- Credible business entity: Private limited companies provide your business with increased credibility with your customers and banks.
Compliance with mandatory filing requirements: A Private Limited Company must file annual returns, have regular board meetings and undergo a statutory audit every year.
Minimum requirements of Private Limited Companies in India are:
- At least 2 directors
