Choosing the right tax accounting consulting firm not only helps businesses comply with current legal regulations but also optimizes tax revenue in the context of constantly changing policies. This article summarizes the evaluation criteria, the Top 10 reputable tax accounting consulting firms on the market, and important considerations for businesses to make the right decision from the start.
Why is choosing the right tax and accounting consulting firm a critical issue starting from 2026?
The period from 2026 onwards is a time of significant changes in tax policy, requiring businesses to update their information promptly to avoid missing out on benefits or facing the risk of retroactive tax collection. The National Assembly approved this on August 24, 2026. Resolution 43/2026/QH16 Regarding the reduction of personal income tax and corporate income tax, it takes effect immediately from the date of signing and applies to the tax periods of 2026 and 2027.
Accordingly, individual business owners and enterprises with annual revenue not exceeding 10 billion VND are entitled to a reduction of 30% in the amount of personal income tax or corporate income tax payable; for enterprises already enjoying tax incentives, this reduction is calculated on the remaining tax payable after deducting the incentives.
This is a prime example of why businesses need a competent consulting firm to keep them updated on newly enacted policies. These policies cannot be automatically applied correctly if the accounting department doesn't review revenue conditions, methods for determining tax reductions, and filing deadlines. A professional tax and accounting consulting firm will help businesses both take advantage of preferential policies and avoid errors in tax preparation. tax report periodically.
Besides policy factors, three reasons make choosing a consulting firm more crucial than ever:
- The frequency of regulatory changes has increased: Numerous Decrees, Circulars, and Resolutions are issued and come into effect almost simultaneously within the same tax period.
- The operating costs of an in-house accounting department are increasing, while the risks of employee turnover and lack of experience in handling complex paperwork persist.
- Tax audits and inspections are becoming increasingly stringent for businesses with related-party transactions and FDI enterprises.

Frequently Asked Questions about Tax and Accounting Consulting Firms
Should newly established businesses hire an accounting and tax consulting firm right away?
Yes. Newly established businesses often lack experience in handling initial tax obligations; outsourcing helps avoid filing errors and saves costs compared to maintaining an in-house accounting department from the start.
How does using an accounting service differ from hiring an in-house accountant?
Service providers have dedicated teams, stay up-to-date on regulations, and are accountable under service contracts, whereas in-house accounting relies on the competence and stability of a single individual.
Should FDI businesses choose Big 4 firms or domestic consulting firms?
Depending on the size and needs, businesses with complex cross-border transactions requiring international reporting standards often choose the Big 4; medium-sized FDI businesses needing cost optimization and close support often choose domestic accounting and tax consulting firms with experience in the FDI sector.
Is it possible to switch consulting firms during the fiscal year?
It is possible, but a complete handover of records and documents, along with data reconciliation between both parties, is necessary to avoid any disruption to timely filing obligations.
Which entities are eligible for the 30% tax reduction under Resolution 43/2026/QH16?
