Tax accounting services in Vietnam

Submitting all tax declarations does not automatically mean an enterprise’s tax accounting records are fully compliant. Every declared figure requires supporting invoices, contracts, payment vouchers, and transaction records as a basis for verification, reconciliation, and explanation during tax audits. To ensure seamless data control from input vouchers to year-end financial reporting, Viet An Tax Agent provides comprehensive tax accounting services, including dossier verification, transaction bookkeeping, data reconciliation, tax return preparation, finalizing financial statements, and handing over accounting books according to the agreed scope. Utilizing professional tax accounting services in Vietnam helps businesses minimize financial risks and maintain strict regulatory compliance.

What are comprehensive tax accounting services in Vietnam?

Comprehensive tax accounting services in Vietnam are performed periodically based on records provided by the business. Viet An receives and verifies vouchers, records arising transactions, prepares tax declarations, tracks figures, and completes accounting books according to the agreed scope of work.

A complete service package typically consists of three primary work groups:

Work group Main content
Input dossier control Receiving, classifying, and verifying invoices, contracts, payment vouchers, and transaction records.
Accounting & tax processing Bookkeeping, data reconciliation, preparing tax declaration dossiers, and determining financial obligations.
Handover & risk alerts Handing over prepared dossiers, notifying tax liabilities, missing documents, and outstanding issues requiring further resolution.

These services are suitable for:

  • Newly established enterprises needing initial accounting setup;
  • Businesses without a stable internal accounting department;
  • Companies with internal accountants that require outsourced accounting services in Vietnam for tax compliance;
  • Enterprises transitioning accounting records from former accountants or service providers to Viet An.

Comprehensive Vietnam tax accounting services do not automatically include all internal financial management, HR administration, physical inventory management, processing prior-period data, or representing the company in tax audits unless explicitly agreed upon. The operational scope, deliverables, and arising fees are specifically defined in the service quotation and contract.

Service scope and fee schedule in Vietnam

Service fees are determined based on the actual processing workload rather than invoice volume alone.

An enterprise with few invoices but active manufacturing, import-export operations, multiple bank accounts, or multiple business locations may require a larger processing scope than a consulting firm with high invoice volume but simple transactions.

Official fee quotes are finalized only after Viet An receives preliminary operational information from the business.

Criteria for fee determination

Quotation calculations consider the following factors:

  • Industry sector and business model;
  • Volume of input and output invoices;
  • Number of bank accounts and transaction volume;
  • Employee headcount;
  • Number of contracts, projects, or sales orders;
  • Complexity of accounts receivable, accounts payable, and inventory management;
  • Fixed assets, tools/supplies, and prepaid expenses;
  • Foreign currency transactions;
  • Import-export activities;
  • Branches, business locations, or dependent units;
  • Condition of accounting data from prior periods;
  • Completion timeline requirements;
  • Custom reporting requests outside standard accounting book systems.

What should a transparent quotation in Vietnam include?

Before signing a contract, businesses should verify whether the quotation fully specifies:

  • Service billing cycle (monthly, quarterly, or annually);
  • Voucher limits or workload caps;
  • Tax returns included within the scope;
  • Preparation of year-end financial statements;
  • Format of accounting book handovers;
  • Scope of bank, debt, and inventory reconciliations;
  • Number of included revisions or supplements;
  • Scope of tax audit explanation support;
  • Data processing fees prior to the handover date;
  • Third-party expenses.

Clearly defining the service scope allows businesses to evaluate quotations on an equal basis, avoiding situations where low initial fees exclude essential year-end financial statements, ledgers, or audit support.

Scope of work by phase in Vietnam

Viet An’s tax and accounting services in Vietnam are implemented across three main phases: enterprise onboarding, periodic operations, and year-end file finalization. Specific scope depends on ledger conditions, business models, and contractual agreements.

Enterprise onboarding

Onboarding workflows differ between newly established companies and businesses transitioning from previous accountants or service providers.

Category Viet An’s work scope Onboarding deliverables
Newly established enterprises Review legal dossiers, tax registration info, digital signatures, e-tax accounts, and e-invoice status. Establish baseline status and identify required initial procedures.
Set up master lists for customers, suppliers, bank accounts, inventory items, assets, and tools. Build initial accounting database framework.
Guide client on collecting invoices, contracts, payment vouchers, and transaction records. Provide periodic document submission checklist.
Assign dedicated personnel, agree on data closing schedules and document transfer methods. Establish bilateral coordination mechanism.
Transitioning enterprises Receive tax returns, financial statements, trial balances, and accounting software data. Confirm opening balance figures.
Inspect debts, bank balances, cash, inventory, assets, loans, advances, and payroll. Identify missing or inconsistent data.
Record notices, requests, or pending matters with tax authorities. Define existing unresolved tax issues.
Classify data by status: complete, needs reconciliation, missing, or belongs to prior period. Prepare onboarding status report.

For businesses transitioning from another accounting provider, Viet An conducts a bookkeeping review and prepares an onboarding status report detailing:

  • Data used for opening balances;
  • Documents requiring client supplementation;
  • Figures requiring confirmation from the former accountant;
  • Discrepancies belonging to periods prior to Viet An’s engagement;
  • Tasks covered under the periodic service package;
  • Items requiring ongoing monitoring.

Documenting record status upfront clearly defines the timeline when Viet An assumes operational responsibility for corporate tax compliance in Vietnam.

Monthly and quarterly tax accounting in Vietnam

Periodic tasks follow a continuous cycle: Receive – Verify – Bookkeep – Reconcile – Declare – Alert

Steps in periodic execution

Content
Receive & classify Organize documents by revenue, expenses, bank, cash, receivables/payables, payroll, inventory, assets, loans, and tax liabilities
Verify documents Cross-check invoices against contracts, delivery notes, acceptance records, bank proofs, and supporting transaction files
Bookkeep transactions Record revenue, expenses, cash/bank entries, debts, payroll, assets, tools/supplies, inventory, loans, and tax items
Reconcile data Verify consistency between invoices, bank statements, debt ledgers, inventory records, payroll, assets, and accounting software
Prepare tax returns Draft monthly or quarterly Value-Added Tax (VAT), Personal Income Tax (PIT), and other tax returns within contract scope
Notify obligations Send clients figures for confirmation, list missing vouchers, and state estimated tax liabilities due
Risk alerts Highlight expenses lacking adequate documentation, unassigned transactions, unreconciled debts, or abnormal numbers

Document verification standards

Viet An checks transaction consistency across related documents:

  • Invoices against contracts and acceptance minutes;
  • Payment amounts against bank statements or bank vouchers;
  • Revenue entries against delivery or service completion data;
  • Salary expenses against timesheets and payment vouchers;
  • Imported inventory against invoices and customs/delivery records;
  • Asset additions against handover minutes and operational start dates.

If supporting grounds are insufficient, transactions are categorized on a missing document list. Viet An does not make assumed bookkeeping entries without necessary client information.

Periodic reconciliation content

Data category Control focus
Invoices and revenue Invoices issued, recorded revenue, and collected cash.
Bank accounts Bank statement transactions against accounting ledger entries.
Receivables and payables Outstanding receivables, payables, settled debts, and unassigned amounts.
Cash on hand Cash receipts, cash disbursements, and physical cash ledger balances.
Inventory Stock in, stock out, ending inventory quantities, and sales data.
Payroll Payroll sheets, statutory deductions, and wage payment proofs.
Fixed assets Purchase records, usage dates, original cost, and depreciation schedules.
Taxes Declared tax returns, paid tax amounts, and remaining tax liabilities.

Post-period risk alert report

After processing data, Viet An notifies the enterprise of items requiring completion:

  • Missing supporting documents, contracts, or payment vouchers;
  • Unassigned bank transactions lacking narrative clarity;
  • Unreconciled customer or supplier debt balances;
  • Expenses lacking sufficient legal grounds for deductibility;
  • Cash on hand balances requiring verification;
  • Inventory stock discrepancies;
  • Fixed assets lacking handover records;
  • Transactions requiring internal decision or executive approval;
  • Pending accounting matters carried over to the next period.

Periodic risk alerts help businesses resolve document gaps ongoingly, avoiding accumulated errors at year-end.

Year-End tax accounting work in Vietnam

At year-end, Viet An consolidates accounting data for the entire fiscal year, verifies balances, executes necessary closing entries, and prepares annual reports within service scope.

Task group Core content
Closing preparation Collect year-end bank statements, inventory counts, debt confirmations, asset lists, loan files, and missing vouchers.
Balance verification Perform a comprehensive bookkeeping review of cash, bank, debts, inventory, assets, tools, prepaid costs, and tax obligations.
Finalizing entries Execute allocations, depreciation, year-end adjustments, revenue/cost transfers, and isolate items needing explanation.
Financial statements Prepare a full set of financial statements under the applicable Vietnamese Accounting Standards (VAS).
Tax finalization Summarize annual revenues, deductible expenses, adjustments, and provisionally paid tax amounts.
Ledger finalization Export complete general ledgers and detailed accounting registers per scope.

Before closing books, the enterprise must confirm or provide additional documentation regarding:

  • Cash on hand and bank account year-end balances;
  • Physical inventory count sheets;
  • Accounts receivable and payable confirmation letters;
  • Fixed asset and tool/supply master lists;
  • Loan contracts and financial expense records;
  • Annual payroll summaries and PIT finalization data;
  • Outstanding missing invoices, contracts, or transaction vouchers;
  • Unrecorded arising transactions.

Annual financial statements prepared under applicable accounting regimes include the Balance Sheet / Statement of Financial Position, Income Statement, Cash Flow Statement (where applicable), Notes to Financial Statements, and Trial Balance.

Year-end tax finalization packages include Corporate Income Tax (CIT) finalization, Personal Income Tax (PIT) finalization, and related schedule attachments within contract scope.

Client deliverables

Service deliverables serve as the tangible basis for evaluating completed work. Businesses should receive complete documentation for audit and archival purposes rather than simple submission notices.

Periodic deliverables

Deliverable Content reflected
Received document list Inventory of documents received from the client during the period.
Missing document list Schedule of missing records and affected accounting entries.
Tax returns & schedules Declared VAT, PIT, and other tax returns within scope.
Submission confirmations Official e-tax system receipt confirmations.
Liability notifications Summary of tax liabilities payable and payment deadlines.
Reconciliation sheets Data reconciliation results per agreed service scope.
Risk alert reports Identified issues requiring client confirmation or supplementation.
Accounting data files Soft-copy reports or exported accounting data files per agreement.

Year-End deliverables

Upon completing annual accounting and reporting tasks, Viet An hands over the following files:

Product group Handover content
Reports & finalizations Complete financial statements, CIT & PIT tax finalization packages, and trial balances.
General ledgers General journal and general ledgers for all active accounts.
Detailed ledgers Detailed registers for cash, bank, receivables, payables, inventory, and assets.
Tracking schedules Asset depreciation schedules, tool allocation sheets, and inventory movement reports.
Electronic data Accounting software data backup files and exported electronic report files.
Handover minutes Formal document handover records confirming transferred physical/digital files.
Outstanding issues list Summary of unresolved document gaps or items requiring ongoing tracking.

Annual unresolved issues report

This list is compiled separately to inform management of items lacking sufficient legal grounds at book closing:

Tracking area Potential arising content
Missing documents Invoices, contracts, or payment vouchers not provided by the business.
Unconfirmed figures Unverified cash, bank, debt, or asset ending balances.
Unassigned transactions Bank deposits or withdrawals lacking clear business narratives.
Pending expenses Expenses lacking sufficient supporting documentation for tax deduction.
Inventory variance Discrepancies between accounting book inventory and physical count sheets.
Prior-Period issues Errors or document defects originating prior to Viet An’s engagement.
Next-Period Carryover Items requiring ongoing tracking, adjustment, or supplementation in subsequent periods.

An unresolved issues report ensures management understands the exact data foundation behind the annual financial statements and establishes a clear action plan for remaining risks.

Document provision schedule and client responsibilities

Category Representative documents
Corporate legal files Enterprise Registration Certificate, Investment Registration Certificate (if FDI), specialized licenses, representative ID, and dependent unit files.
Sales revenue Output e-invoices, sales contracts, delivery notes, acceptance minutes, liquidation records, and bank payment receipts.
Operating expenses Input e-invoices, purchase contracts, payment requisitions, acceptance records, and bank payment vouchers.
Cash & Bank Bank statements, payment orders, credit/debit advice notes, cash receipt vouchers, cash payment vouchers, and advance settlement files.
Payroll & HR Labor contracts, timesheets, payroll registers, salary decisions, and wage payment proofs.
Inventory & assets Goods receipt/issue notes, physical count sheets, consumption norms, asset files, handover minutes, and allocation tables.
Import & export Foreign trade contracts, customs declarations, commercial invoices, packing lists, bills of lading, and international bank payment vouchers.
Prior-Period Data Financial statements, accounting ledgers, tax returns, debt ledgers, inventory reports, and software backup files.

Simply holding an e-invoice does not automatically constitute a complete legal document package. Businesses must retain records reflecting transaction execution, delivery, and payment.

The timeline below represents an internal coordination schedule between the client and Viet An:

Timeline Client responsibility Viet An deliverable
During arising period Retain invoices and transaction records. Provide guidance on document completion.
Day 01 to 05 of following month Transfer prior month’s documents. Receive, organize, and classify files.
After receiving missing list Supplement records or clarify entries. Update data processing status.
Before finalizing figures Confirm revenue, expenses, and pending items. Finalize declaration dataset.
Before filing deadline Approve figures and arrange tax payments. Submit tax returns within scope.
Year-End Provide physical inventory counts & debt confirmations. Close ledgers & prepare financial statements.

Businesses filing taxes quarterly should still transmit data monthly to allow early document verification and error detection.

Handling vouchers provided after data cutoff date

When documents are transferred after the agreed data cutoff date, Viet An executes a structured 6-step workflow:

Frequently Asked Questions

Does Viet An accept new clients mid-year?

Yes. Before commencing periodic work mid-year, Viet An conducts a bookkeeping review of opening balances, filed returns, software data, and handover records from the former accountant. Resolving prior discrepancies is quoted separately.

Must clients transfer original hard-copy vouchers or digital scans?

Clients can transfer digital scans or e-files for periodic processing. However, the enterprise remains responsible for archiving original hard-copy documents and providing them upon request during tax inspections.

Should quarterly filing businesses send documents monthly?

Yes. Transmitting data monthly allows early identification of missing invoices, unassigned bank entries, debt variances, and inventory discrepancies.

How are vouchers provided after tax return submission handled?

Viet An reviews the affected tax period, assesses financial impacts, and advises on filing supplemental tax returns. Additional processing fees apply if significant adjustments are required.

Does the regular package cover prior-year accounting data?

No. Periodic fees apply to transactions arising from the contract start date forward. Reviewing or correcting past data requires a separate survey and quotation.

What accounting books does an enterprise receive after year-end closing?

Depending on the contract, clients receive a complete set of financial statements, CIT/PIT tax finalization returns, trial balances, general ledgers, detailed registers, asset depreciation schedules, and software backup files.

Do fees change if transaction volume increases significantly?

Yes. If voucher volume, headcount, bank accounts, or business locations exceed initial contract tiers, both parties adjust the package to reflect the new workload.

Does periodic service include tax audit defense representation?

Routine explanations for returns prepared by Viet An are supported under contract. Comprehensive multi-year tax audit representation or handling extensive tax inspections is provided as a separate professional service.

How are multi-branch companies quoted?

Fees are determined by the number of dependent units, transaction locations, accounting methods, local filing obligations, and data consolidation requirements.

Can Viet An coordinate with an enterprise’s internal accountant?

Yes. A clear responsibility matrix defines tasks executed by internal staff versus tasks verified, declared, and finalized by Viet An.

Are figures sent for client confirmation prior to tax submission?

Yes. Key indicators, projected tax obligations, and pending issues are sent for executive confirmation prior to final submission.
