Starting is easy. Starting correctly is the work.
Every business has different operational, financial and taxation requirements, which is what makes the choice of entity consequential rather than administrative. At Ratnesh Thakur & Co. we provide end-to-end business registration for entrepreneurs, startups, MSMEs, professionals and established businesses across India.
With over 35 years of practice, our Chartered Accountants, Company Secretaries, tax consultants and legal advisers guide clients through every stage — from selecting the structure to obtaining statutory registrations and regulatory approvals — managing the documentation and filings so you can get on with building the business.

This page is for you if
- You're starting a business and don't yet know which structure fits
- You're bringing in a partner and need the ownership terms documented
- You've outgrown a proprietorship and want to convert to an LLP or company
- An investor, bank or customer has asked you to incorporate
- You're setting up a non-profit and need Section 8 recognition
Five common choices, side by side
Answer two questions and we'll highlight the structures that usually fit. It's a starting point for the conversation, not a substitute for one.
Narrow it down
Two questions. No email required.
| Proprietorship | Partnership | LLP | OPC | Private Limited | |
|---|---|---|---|---|---|
| Owners required | 1 | 2 or more | 2 designated partners | 1 member + 1 nominee | 2 shareholders, 2 directors |
| Liability | Unlimited — personal assets exposed | Unlimited, joint and several | Limited to contribution | Limited to shareholding | Limited to shareholding |
| Separate legal entity | No | No | Yes | Yes | Yes |
| Registered with | No central registry | Registrar of Firms (optional) | MCA | MCA | MCA |
| Annual compliance | Lightest | Light | Moderate | Higher | Highest |
| Outside investment | Not practical | Difficult | Limited appetite from VCs | Not until converted | Standard vehicle |
| Typically suits | Freelancers, small retail, consultants | Family firms, small trading businesses | Professional practices, service firms | Solo founders wanting a corporate shell | Startups and businesses planning to scale |
Indicative comparison for orientation only. Thresholds, exemptions and conversion rules change, and the right answer depends on your turnover, sector and plans. We'll confirm what applies to you before anything is filed.
What we handle, end to end
A sole proprietorship is one of the simplest and most popular forms of business ownership for individual entrepreneurs — ideal for small businesses, consultants, freelancers, retailers and service providers wanting minimal compliance and complete operational control.
We obtain the registrations that give a proprietorship its legitimacy: GST registration, Shop & Establishment licence, MSME registration, Professional Tax registration where applicable, and other statutory requirements. We also advise on tax implications, accounting systems and future scalability.
Suitable for businesses owned and managed by two or more individuals. A properly drafted partnership deed provides clarity on ownership, responsibilities, profit-sharing and dispute resolution — the absence of one is where most partnership disputes begin.
We draft the deed and obtain PAN, GST registration, MSME registration and other business registrations, then advise partners on taxation, accounting, statutory compliance and future conversion into an LLP or company if expansion requires a more structured entity.
An LLP combines the flexibility of a partnership with the protection of limited liability — an effective choice for professionals, service firms, startups and growing businesses.
We provide complete LLP incorporation: name reservation, Digital Signature Certificates, Director Identification Numbers, LLP agreement drafting, PAN, TAN, GST registration and MCA filings, and we make sure you understand the ongoing obligations under the LLP Act before you commit to the structure.
One of the most preferred structures for startups and growing businesses seeking credibility, investment and long-term expansion.
We manage the complete incorporation process: name approval, Digital Signature Certificates, Director Identification Numbers, Memorandum and Articles of Association, incorporation filings with the MCA, PAN, TAN and initial statutory registrations — followed by guidance on post-incorporation compliance including ROC filings, accounting, GST and board meeting requirements.
For entrepreneurs who want the benefits of a corporate entity without bringing in additional shareholders.
We handle the complete incorporation formalities, statutory documentation, MCA filings, PAN, TAN, GST registration and ongoing compliance — and advise on conversion into a Private Limited Company as the business expands past the applicable thresholds.
Organisations formed for charitable, educational, social welfare, environmental or non-profit objectives often choose the Section 8 structure for its credibility and regulatory recognition.
We assist with the incorporation process, constitutional documents, licensing, MCA approvals, PAN, TAN and statutory registrations, plus guidance on compliance requirements, accounting standards, Income Tax exemptions, CSR eligibility and annual regulatory filings.
The Government of India offers various incentives for eligible startups under the Startup India initiative. We help entrepreneurs obtain recognition while making sure eligibility conditions and documentation are properly fulfilled.
Our startup consultancy covers structure selection, incorporation, DPIIT recognition, MSME registration, GST registration, accounting system setup, compliance planning, financial projections and investor documentation.
Digital Signature Certificates and Director Identification Numbers are prerequisites for incorporation and for electronic filing with government authorities.
We obtain, renew and update DSCs and DINs, and provide support for DSC registration, token management, DIN KYC and other MCA requirements so that statutory filing is never held up by an expired certificate.
Every business entity requires various tax registrations before commencing operations. We obtain PAN, TAN, GST registration, Professional Tax registration where applicable, and other statutory registrations necessary for lawful operation — completed accurately and without the delays that hold up a first invoice.
Registration is the beginning of the compliance journey, not the end of it. Every registered entity carries ongoing obligations across taxation, accounting, ROC filings, GST returns, TDS, payroll and statutory records.
Our annual compliance management covers GST return filing, income tax return filing, ROC and MCA compliance, accounting and bookkeeping, payroll and TDS management, annual financial statements, business licence renewals and compliance calendar management.
What to have ready before you call
Tick these off as you gather them. Nothing is stored — this is just a working list for your own reference.
For every director or partner
For the registered office
Decisions to bring
Requirements vary by entity type and by the state in which the office is registered. Foreign nationals and NRI directors need additional attestation — ask us before you start collecting.
From first call to certificate of incorporation
Structure consultation
We go through what the business does, who's involved, how it will be funded and what you expect over three years — then recommend a structure and explain the compliance it carries. You leave with a written scope and fee.
Digital signatures and name approval
DSCs are issued for each proposed director and the name application goes in. We check proposed names against existing companies and trademarks first, because a rejected name is the most common cause of delay.
Drafting and execution
Memorandum and Articles, or the partnership or LLP agreement, are drafted around the decisions taken at step one — shareholding, roles, capital and the terms that matter if the founders later disagree.
Filing with the MCA
The incorporation application is filed with all attachments, along with PAN and TAN. We respond to any resubmission queries directly rather than passing them back to you.
Incorporation and opening registrations
Certificate of Incorporation issued, followed by the bank account documentation, GST registration, MSME registration and any licences your sector requires.
Your compliance calendar goes live
Every recurring obligation the new entity carries — ROC filings, GST returns, TDS, payroll, licence renewals — is scheduled, with reminders before each date rather than after.
Indicative timeline for a Private Limited Company where documents are complete and the first name choice is approved. LLP and OPC timelines are similar; proprietorship and partnership are usually faster.
Registration is the easy part. Year two is the test.
Plenty of services will incorporate a company cheaply. Fewer are still answering the phone when the first ROC notice arrives.
35+ years of practice
The firm has incorporated businesses through three regimes of company law. Structure advice comes from having seen how these choices age.
Complete setup, one roof
Incorporation, PAN, TAN, GST, MSME, licences and the first year's compliance handled by the same team.
Chartered Accountants and Company Secretaries
Structure, tax and secretarial questions answered by the people qualified for each, not by a single generalist.
Guidance on structure, not upselling
If a proprietorship is genuinely right for you, we'll say so — and register it — rather than sell you a company you don't need.
Post-registration support
Annual compliance packages so the entity we set up stays in good standing without you tracking dates.
Transparent and confidential
Written scope and fee before work starts. Your documents stay with the people working on the file.
Structures we register
Before you decide
What usually comes next
Total Compliance
Annual ROC and MCA filings, statutory registers and secretarial records for the entity once it exists.
Direct & Indirect Taxation
Income tax, GST and TDS from the first return onward, including notices and representation.
Licences & Registrations
FSSAI, MSME, Trademark, Shop & Establishment and Professional Tax, depending on your sector.
Bank Finance Assistance
CMA data, project reports and loan documentation when the new entity needs working capital.
