Accounting tasks are vital to any business, but managing them in-house can be challenging, especially in Vietnam’s dynamic regulatory environment. For startups, SMEs and foreign-owned businesses, keeping up with bookkeeping, payroll, tax filings and financial reporting can require significant time and knowledge of local requirements.
Accounting outsourcing involves engaging an external provider to manage some or all of these functions, depending on the business’s needs. In Vietnam, this can include bookkeeping, tax compliance, payroll, financial reporting and other accounting support, while the business retains oversight of its financial operations.
What are the 5 Most Common Taxes in Vietnam?
Corporate Income Tax (CIT) is a tax on a company’s taxable income. Vietnam’s standard CIT rate is 20%. Under the 2025 Corporate Income Tax Law and its implementing Decree No. 320/2025/NĐ-CP, a 15% rate applies to enterprises with annual revenue of no more than VND 3 billion, while a 17% rate applies to enterprises with annual revenue above VND 3 billion and up to VND 50 billion, subject to the applicable conditions. Separate preferential CIT rates may apply to qualifying investment projects and activities.
2026 update: Resolution No. 43/2026/QH16 provides a 30% reduction in CIT payable for qualifying enterprises with annual revenue of no more than VND 10 billion for the 2026 and 2027 tax years, subject to specified conditions. Businesses should assess eligibility before applying the reduction.
Value-Added Tax (VAT) is an indirect tax on goods and services consumption. The standard rate is 10%, but Vietnam temporarily reduced it to 8% to boost economic recovery. This 2% reduction, first introduced in 2022, is extended until December 31, 2026. Essential goods and certain services are taxed at 5% or 0%, while others are exempt. Businesses must apply the correct rate, file VAT returns monthly or quarterly, and issue electronic invoices. Tax authorities have also tightened VAT compliance, requiring proper e-invoicing and documentation for VAT refunds.
Personal Income Tax (PIT) applies to taxable income earned by individuals in Vietnam. For resident individuals, employment income is taxed progressively at rates from 5% to 35% under the new Personal Income Tax Law, with the highest 35% rate applying to taxable income above VND 1.2 billion per year. Non-residents are generally subject to a 20% rate on Vietnam-sourced employment income. From 2026, businesses must also consider updated PIT rules on tax deductions, filing and finalisation when managing payroll.
Foreign Contractor Withholding Tax - FCWT
Foreign Contractor Tax (FCT) applies to certain payments made by Vietnamese businesses to foreign contractors that do not have a licensed presence in Vietnam. Under the direct method, FCT generally comprises VAT and Corporate Income Tax (CIT), with rates determined by the nature of the activity. Current rates include 5% VAT and 5% CIT for general services, 3% VAT and 2% CIT for transportation, 3%–5% VAT and 2% CIT for construction and installation, 5% VAT and 10% CIT for restaurant, hotel and casino management services, and 0% or exempt VAT with 10% CIT for royalties, depending on the specific transaction. Supply of goods is generally subject to 1% CIT and 1% VAT or VAT exemption, depending on the circumstances.
Vietnam abolished the annual business licence fee from 1 January 2026. Businesses must still comply with their other applicable tax, accounting, payroll and reporting obligations.
Vietnam enforces e-filing and e-invoicing for all taxes. Declarations for CIT, VAT, PIT, and others must be submitted via the national electronic tax portal, using digitally signed e-invoices. Key deadlines include:
Vietnam uses electronic systems for tax administration and electronic invoicing is required for businesses within the applicable rules. Filing and payment deadlines vary by tax type. For example, monthly VAT returns are generally due by the 20th of the following month, while quarterly provisional CIT payments must generally be made by the 30th day of the following quarter. Annual CIT finalisation is generally due by the last day of the third month following the end of the financial year.
Partnering with an accounting outsourcing firm helps ensure timely submissions, compliant software, and full adherence to Vietnam’s tax regulations—avoiding penalties or reporting errors.
Vietnam provides CIT incentives for qualifying investment projects and activities. Depending on the applicable preferential rate and eligibility conditions, incentives can include a CIT exemption of up to four years followed by a 50% reduction for up to nine years. Other preferential arrangements may apply to specific projects, sectors or investment activities. Businesses should assess the conditions before assuming an incentive applies.
Accounting outsourcing involves hiring external experts to manage your company’s accounting and finance tasks. In Vietnam, it’s a common, cost-effective choice for foreign and local businesses aiming for compliance and efficiency.
Providers typically handle bookkeeping, tax filings, payroll, reporting, and compliance, acting as an off-site accounting team aligned with Vietnamese laws. They stay current with regulatory changes, helping companies avoid errors and penalties.
Outsourcing doesn’t mean losing control—it allows business owners to focus on growth while professionals ensure financial accuracy. For startups and SMEs, outsourcing can provide access to additional accounting expertise without building a larger internal finance team.
Payroll in Vietnam is complex, involving labour laws, taxes, and insurance contributions such as social, health, and unemployment insurance. Regulations change frequently, making compliance challenging.
Outsourcing payroll ensures accurate calculations, timely payments, and full compliance with government rules. Providers handle tax deductions, leave tracking, and benefits, preventing costly errors and saving HR teams valuable time. Partnering with an accounting outsourcing firm keeps payroll smooth and compliant across all updates.
Bookkeeping is the core of accounting, involving daily recording of all sales, purchases, expenses, and receipts. These records feed into general accounting, which produces financial statements and summaries. Because the work is detail-heavy, even small errors can lead to inaccurate reports or poor decisions.
By outsourcing bookkeeping and ledger management, companies ensure every transaction is accurately recorded under proper accounting standards. Providers use cloud-based accounting software to automate entries, reconcile bank statements, and close books monthly. With an accounting outsourcing partner in Vietnam, businesses always have up-to-date, reliable financial data for timely decision-making.
Preparing financial statements (balance sheet, income, and cash flow) and management reports is essential for compliance and business planning. In Vietnam, companies must follow Vietnamese Accounting Standards (VAS) and, when required, submit audited financials.
If accounting and bookkeeping are already outsourced, it’s practical to outsource reporting too. The same provider has all financial data, enabling quick, compliant report generation. They ensure accuracy in tax adjustments, depreciation, and disclosures, and can produce tailored management reports like profit analysis or cash flow forecasts.
For many foreign businesses or startups in Vietnam, hiring a full-time chief accountant is not practical. Through the “Nominee Chief Accountant” service, an outsourcing firm can assign a certified professional on a part-time basis to fulfill this legal role. The nominee acts as the company’s chief accountant of record, signing documents, overseeing accounts, and liaising with tax authorities. This helps companies meet legal requirements and ensure compliance without the cost of a full-time hire. The nominee also coordinates with the accounting team and can assist with tasks such as opening bank accounts.
Outsourcing accounting helps companies cut costs by replacing expensive in-house teams with a fixed service fee. It eliminates costs for salaries, training, software, and office space. Professional providers also reduce the risk of costly compliance errors or missed deductions. Although there is a service fee, it is offset by avoiding fines and freeing up capital. In short, outsourcing delivers expert service at a predictable and often much lower cost than maintaining an internal team.
By outsourcing accounting, businesses can focus on revenue-generating activities instead of routine bookkeeping or tax work. This allows managers to spend more time on clients, sales, and strategy.
With professionals handling accounting accurately in the background, companies improve productivity, build stronger client relationships, and achieve higher profits through better focus and efficiency.
Vietnam’s tax and accounting rules are complex and frequently updated. Outsourcing to a local accounting expert ensures full compliance with current laws and reduces the risk of penalties or audits.
These firms stay updated, use internal checks, and handle all filings correctly and on time, helping protect a company’s reputation and operations.
A reliable outsourced accounting team provides timely, accurate financial reports, helping management make quick and informed decisions. They ensure smooth day-to-day operations—closing books, paying vendors, and generating reports on time—while also offering strategic insights from their experience. This real-time visibility improves planning and responsiveness to market changes.
A key concern in outsourcing is losing oversight of financial matters. Miscommunication can cause errors or delays if expectations are unclear. To prevent this, set up clear communication channels, assign a dedicated contact, and agree on regular reporting schedules. Using cloud-based accounting systems also allows real-time access to financial data. With open communication and regular reviews, you can stay informed and maintain full control over your accounts.
Sharing financial data with a third party raises security concerns. However, reputable firms use encrypted systems, secure transfers, and staff NDAs to protect client data. Always check a provider’s security practices and include confidentiality clauses in your contract. You may start with less-sensitive tasks before expanding the scope as trust builds. With proper safeguards and a reliable partner, businesses can outsource accounting confidently without compromising sensitive information.
Outsourcing accounting in Vietnam starts with deciding which financial and compliance functions your business needs support with. Under Vietnam's current accounting framework, businesses can engage eligible accounting service providers to perform accounting or chief accountant services through a written contract.
Managing accounting and tax requirements in Vietnam requires consistent attention to local rules, reporting deadlines and financial records. For startups, SMEs and foreign-owned businesses, outsourcing can provide practical support across bookkeeping, payroll, tax compliance and financial reporting without building a larger in-house finance function.
The right approach depends on the business's size, structure and reporting needs. Clear responsibilities, qualified support and regular review can help businesses keep their accounting processes organised as requirements change.
