The process of converting a sole proprietorship into a company is no longer a "precautionary" option but has become an essential requirement for businesses aiming for sustainable growth. This article, written from the perspective of a chief accountant, focuses on clarifying the entire transition process from a sole proprietorship to a company, from final settlement and bookkeeping before conversion, to registering the company in accordance with regulations, and establishing an accounting, tax, and electronic invoicing system after conversion. This helps business owners reduce the risk of tax arrears, avoid accounting errors, and maximize the benefits of preferential policies in 2026 from the very beginning.
Why is 2026 the golden time for transformation?
Entering 2026, the legal landscape for business in Vietnam will undergo significant changes. The implementation of Resolution 198/2025/QH15 has provided a clear roadmap for professionalizing economic entities. In particular, according to the tax strategy, the application of lump-sum tax will gradually be replaced by a self-declaration system based on electronic invoices generated from cash registers.
Currently, household businesses are facing three major bottlenecks:
- Limitations in credibility: Difficulty participating in bidding or signing contracts with large partners requiring legal status and deductible VAT invoices.
- Management risk: The eTax Mobile system allows tax authorities to closely monitor fluctuations in personal cash flow, making the separation of business assets and household assets essential.
- Invoice pressure: The requirement to issue invoices for each individual transaction is overwhelming the operational machinery of sole proprietorships if they lack the support of a corporate accounting system.
According to the 2026 tax law, the lump-sum tax system will be eliminated. Household businesses will have to pay taxes based on a percentage of their actual revenue or consider converting to a corporate model to apply for a more transparent tax mechanism and enjoy appropriate preferential policies.
Settling accounts and cleaning up business records (before conversion)
This is a crucial stage that many household owners often overlook, leading to the transfer of old tax risks to the new legal entity. Based on practical experience, settling all old tax debts is a prerequisite for the Department of Planning and Investment to approve the conversion application.
Reviewing outstanding tax obligations
Before beginning the accounting process for a sole proprietorship transitioning to a company, the sole proprietor must ensure that it has no outstanding tax debts.
- Business License Tax: Check the payment status on form 01/MBAI.
- VAT and Personal Income Tax: For business households filing tax returns, it is necessary to review monthly/quarterly tax returns. Ensure that the figures on the tax returns match the revenue recorded on issued invoices.
- Using eTax Mobile: Householders should log into the app to check the "Tax Obligations" section to identify any outstanding late payment penalties or accrued interest.
Inventory management
A classic problem in the accounting process of a sole proprietorship transitioning to a company is inventory. Sole proprietorships often purchase goods in small quantities without complete input invoices.
- Conduct an inventory and categorize goods into two groups: those with invoices and those without invoices.
- For goods purchased from small-scale suppliers, a list of goods purchased without invoices (Form 01/TNDN) must be prepared accurately reflecting the actual situation. However, note that when transferred to the enterprise, these assets must be revalued by a valuation council or appraisal organization to increase the charter capital or be recorded as assets of the enterprise.
Finalize invoice figures and settle labor issues.
Household heads need to prepare a report on invoice usage up to the closing date. They must also carry out procedures to cancel old paper or electronic invoices of the business. Regarding labor, if there are employees, new employment contracts must be signed under the company's name to ensure employees' rights regarding social insurance and seniority.
Business registration process on the sole proprietorship platform
The accounting process for a sole proprietorship transitioning to a company is as follows:
Step 1: Prepare detailed legal documents.
To ensure a smooth and compliant transition from a sole proprietorship to a company, without requiring multiple additional documents, the business owner needs to prepare a complete set of legal documents from the outset. Below is a list of mandatory documents required when carrying out the accounting process for a sole proprietorship transitioning to a company, as per current regulations.
|
Documents |
| Original Business Registration Certificate |
| A certified copy of the Tax Registration Certificate. |
| Company charter |
| Business registration application form |
| List of members (for limited liability companies with two members, partnerships) or list of shareholders for joint-stock companies. |
| Valid copies of ID cards/Citizen Identification Cards/Passports of members and shareholders. |
| In the case where the contributing member is an organization: A certified copy of the Establishment Decision, Business Registration Certificate, or equivalent document. |
| Authorization letter for the applicant |
| A certified copy of the authorized person's ID card/citizen identification card/passport. |
Preparing all the above documents accurately and completely will help shorten the processing time, minimizing the chances of having your application rejected or being asked for additional information by the business registration authority. Immediately after completing this set of documents, the household business owner can proceed to submit the business registration application on the National Information Portal, and simultaneously prepare for the next steps in the process of converting the household business to a company, such as making a company seal, opening a bank account, and filing initial tax returns.
Step 2: Submit application
Businesses can submit their applications directly to the Business Registration Office – Department of Planning and Investment where the business is headquartered, or submit them online at this address. https://dangkykinhdoanh.gov.vn/.
Step 3: Obtain the license
After approximately 3 working days, if the application is valid, the business receives the Enterprise Registration Certificate (ERC). The next step is to have the company seal engraved.
Step 4: Procedures at the Tax Authority after licensing.
This is the important point:
- Businesses must submit Form 08-MST to the tax authority directly managing the former household business to notify them of the conversion and closure of the household business tax code.
- In cases where the business's tax identification number (TIN) cannot be directly transferred, the business must complete tax settlement procedures and close the old TIN within 10 days of receiving the new license.
Although the process of registering a household business to become a company has been standardized and can be completed relatively quickly online, in reality, completing the administrative procedures is only the beginning. To avoid risks related to taxes, accounting, and legal obligations arising after the conversion, household business owners need to pay special attention to the following important points in the accounting process for household businesses transitioning to companies.
Important notes in the accounting process for converting a sole proprietorship into a business enterprise.
Tax considerations when converting from a sole proprietorship to a company:
Regarding tax identification numbers:
- After the conversion, the business is assigned a new tax identification number according to its Business Registration Certificate.
- The tax identification number of the old business household has expired during business operations, but it will continue to be used as the personal tax identification number of the household head for any tax obligations arising later.
Regarding tax obligations before the conversion:
- Household businesses are responsible for paying all taxes, fines, and late payment penalties to the tax authorities before the conversion.
- If tax obligations have not been fully settled, the newly established business will inherit all tax rights and obligations of the previous household business.
Regarding the financial responsibilities of the head of household:
- Regardless of whether the business is converted to a limited liability company or a joint-stock company, the business owner remains liable with all of their assets for the outstanding debts and financial obligations of the previous business.
After understanding the key tax, legal, and financial responsibilities involved in the process of converting a sole proprietorship into a company, the next step for the business owner is to comprehensively assess the benefits and drawbacks of the conversion. A thorough understanding of both sides will help the business make a decision that aligns with its scale, resources, and long-term development goals.

Benefits of model switching
Converting from a sole proprietorship to a corporate model not only meets legal requirements in an era of increasingly stringent tax management, but also opens up many advantages in terms of legal, financial, and expansion capabilities. Specifically, businesses will receive the following outstanding benefits:
- Establishing independent legal status: Businesses operate as legal entities, possessing their own seals and identification systems, making civil transactions, contract signing, bank loans, and working with partners more transparent and professional.
- Limited liability: Business owners are only liable for financial obligations to the extent of their contributed capital, thereby minimizing personal risk compared to the sole proprietorship model.
- Expanding fundraising possibilities: When operating as a business entity, receiving capital contributions from individuals and other organizations becomes more legal and convenient, and it also makes it easier to access credit from banks and financial institutions.
- Increased opportunities for development and enhanced position: Businesses have the opportunity to participate in industry associations, bid on projects, and cooperate with major partners, thereby expanding their production and business scale and strengthening their reputation in the market.
Government support policies for household businesses transitioning to enterprises:
- The initial business registration fee is waived, including the cost of publishing the business registration details.
- Business license fees are waived for the first three years from the date of initial issuance of the Business Registration Certificate.
- The assessment and initial licensing fees are waived for conditional business sectors and professions as stipulated by regulations.
- Receive free consultation and assistance in drafting business registration documents, helping to minimize legal errors during the initial stages.
Free guidance on tax procedures and accounting regulations is provided for the first three years of operation, which is especially helpful for newly transitioned businesses. - Temporary exemptions and reductions in corporate income tax may be applied if the conditions stipulated in current tax laws are met.
Eligibility requirements for support policies: Household businesses must have been registered and operating continuously for at least one year prior to the initial issuance of their business registration certificate.
Limitations when converting from a sole proprietorship to a company.
Despite the legal benefits and scalability, many household businesses still have reservations about transitioning to a corporate model, even when their revenue is stable. Common concerns that cause many household businesses to hesitate in the accounting process of transitioning from a household business to a corporate model include:
- Increased tax burden: When becoming a business, the business owner must fulfill more tax obligations than a household business, including business license fees, value-added tax, corporate income tax, personal income tax for employees, and other taxes arising from specific sectors such as environmental, import-export, or special consumption tax.
- Higher accounting and tax operating costs: Businesses are required to organize an accounting system, incurring costs for hiring accountants or accounting services, and must also invest in digital signatures, electronic invoices, and software for tax declaration and management.
- Strict accounting and reporting requirements: Unlike sole proprietorships, businesses must fulfill all obligations regarding periodic tax declarations and settlements, prepare financial statements, report on invoice usage, and ensure that all data is recorded correctly according to accounting standards and within the deadlines stipulated by law.
- Labor management is more complex: Issues related to recruitment, termination of employment contracts, wages, and social insurance must all strictly comply with legal regulations, increasing the responsibility and risk for businesses if mistakes are made.
- Increased administrative procedures and compliance costs: Businesses have to meet more requirements regarding insurance, labor, fire safety, and other administrative procedures, thereby increasing fixed costs and creating certain pressure in the operation of production and business activities.
In summary, the process of converting a sole proprietorship into a business entity is a strategic step to enhance transparency, manage risks, and expand business scale. This article analyzes the entire conversion process, from cleaning up books and fulfilling tax obligations to selecting the appropriate business type, preparing complete legal documents, and establishing an accounting system, tax filing, and electronic invoicing after conversion. It also highlights the significant benefits, such as the right to issue VAT invoices and enhanced legal credibility, but also the limitations and risks related to taxes, accounting costs, administrative procedures, and labor management that business owners need to be aware of. Understanding these steps and risks will help the newly converted business comply with the law, optimize costs, and operate efficiently from the outset.

Answering questions about the accounting process for converting a sole proprietorship into a business enterprise.
When converting from a sole proprietorship to a company, is the old tax identification number still valid?
The tax identification number of the household business will cease to be valid during business operations. The new business will be issued a separate tax identification number according to the business registration certificate, and the old tax identification number will still be used for the household business owner's personal tax obligations.
Can a sole proprietorship that has not yet fulfilled its tax obligations convert its business?
Household businesses must fulfill all tax obligations before conversion. If there are outstanding tax debts, the new business will inherit all obligations, and the household owner will be liable with all of their personal assets.
Do businesses have to pay more taxes than household businesses?
Yes. Businesses must pay all applicable taxes: business license tax, VAT, corporate income tax, personal income tax for employees, and other taxes depending on the industry. Tax rates are generally higher than for household businesses, but they receive preferential treatment from the government.
How will HR and social insurance procedures change after the transition?
Businesses must strictly adhere to regulations regarding recruitment, labor contracts, social insurance contributions, etc. Dissolution or dismissal must also follow legal regulations, lacking the flexibility of sole proprietorships.
Is the accounting system for businesses more complex than that for sole proprietorships?
It's very complex. Businesses must maintain accounting records, file tax returns, and prepare financial statements according to accounting standards, ensuring compliance with the law and deadlines. If you don't have a firm grasp of the process, you should hire professional accounting services to avoid the risk of tax arrears and tax assessments.
