Corporate Accounting Services in Vietnam

Updated 2026-07-04

Running a company in Vietnam means keeping the books to local standards and filing with the tax authority on a fixed schedule — whether or not you have revenue yet. Many foreign-invested companies and smaller businesses outsource all of it to one firm on a monthly retainer. Here is what a proper accounting package covers, and how InTimeVisa handles it for you.

Who needs outsourced accounting

Every company in Vietnam has monthly and quarterly compliance obligations from the day it is incorporated. Hiring a qualified in-house chief accountant is expensive and often unnecessary for a small or newly formed entity.

Outsourcing makes sense for two common cases:

• FDI companies — foreign owners who need the books kept correctly in Vietnamese and reported in a language they can follow, without hiring a local finance team on day one
• SMEs and startups — businesses with real activity but not enough volume to justify a full-time accountant
• Dormant or early-stage entities — companies that still must file 'nil' returns on time to stay compliant, even before they trade

Bookkeeping to Vietnamese standards

The core of the service is keeping your books under Vietnamese Accounting Standards (VAS) — the ledger, chart of accounts, and records that every filing and financial statement is built on. Getting this right from the start is what prevents problems later when the tax authority reviews your file.

Each month we record your transactions, reconcile bank movements, track receivables and payables, and keep the supporting documents organized so your file stands up to scrutiny.

E-invoices and monthly tax filing

Vietnam runs on electronic invoices. Under Decree 70/2025, e-invoices must be set up and issued correctly, connected to the tax authority's system. We help set up your e-invoice provider and issue invoices properly so your output records are clean.

Two taxes are filed on a recurring monthly or quarterly cycle, depending on which basis your company falls under:

• VAT (GTGT) — value-added tax, filed monthly or quarterly
• PIT (TNCN) — personal income tax withheld on employee salaries, also filed monthly or quarterly

Corporate income tax — how it actually works

Corporate income tax (CIT / TNDN) is the point most owners misunderstand. There is no monthly or quarterly CIT return. Instead:

This is a two-part rhythm — pay provisionally through the year, then reconcile and file once. We calculate the quarterly payments and prepare the annual finalization so there are no surprises at year end.

• Each quarter you make a provisional CIT payment based on estimated profit — a payment, not a filed return
• Once a year, at the annual finalization (quyết toán), the CIT return is filed and the final tax is settled against what was already paid

Financial statements and the tax authority

At year end we prepare your statutory financial statements — the balance sheet, income statement, and notes required by law — and file them together with the annual tax finalization.

When the tax authority (cơ quan thuế) sends a query or opens an audit, we deal with it: we explain your records, prepare the responses, and represent your bookkeeping. Because we kept the file properly all year, these reviews are far less stressful.

The tax authority remains the decider; our role is to keep you compliant, respond correctly, and make sure nothing is filed late.

How a monthly retainer works

Accounting is ongoing, so it is billed as a monthly retainer rather than one-off. What you pay depends on transaction volume, number of invoices and employees, and whether you need reporting in English or another language — a dormant company costs far less than an active trading one.

We give you a fixed monthly quote up front after understanding your business, with the annual finalization scoped clearly. You only pay once you accept the quote — there is no obligation to review it.
