Tax filing review service
Professional service to review customers’ declarations, invoices, books and financial reports, detect errors early and make adjustments before submission — saving costs, avoiding fines and building trust with partners.
Introducing tax file review service
Tax audit is the process of reviewing and comparing tax declarations, books, invoices and related documents to detect errors, recording gaps or inconsistencies with current tax regulations. The goal is to help businesses make timely adjustments before submitting documents or before being audited.
Distinguishing between periodic declaration and final settlement: declaration is the work of making periodic declarations (monthly/quarterly/yearly) and submitting them to the tax authority; final settlement is synthesizing and comparing final data to determine official tax obligations; and review is an independent step, of an inspection/diagnostic nature before or in parallel with the other two tasks, focusing on detecting risks and issues that need to be handled.
Importance for businesses: a thorough review can detect missing input invoices, unproven expenses, errors in VAT/CIT/PIT calculation — thereby avoiding additional collection, administrative fines and wasting time explaining to the authorities. Especially for businesses preparing to raise capital, M&A or borrow from banks, a transparent set of documents will create greater trust with investors and banks.
When do businesses need to review tax records?
Before the corporate income tax and personal income tax settlement period
It is recommended to review at least 30-45 days before the settlement to detect invalid expenses, missing invoices, or errors in the allocation of revenue/expenses. Recommended action: create a declaration checklist, compare the books with the financial statements and make adjustments before submitting.
When changing accounting personnel or chief accountant
Transferring books is a time when errors are likely to arise due to different accounting methods. Reviewing helps to check for consistency, identify missing documents and guide new staff. Suggestion: use short-term review services to ensure continuity and reduce risks for the business.
When preparing to raise capital, M&A or bank loans
Investors and banks carefully review books, financial statements and tax records; a transparent report increases reliability and negotiating value. Action: use a review service to standardize documents, prepare a risk summary report before meeting with investors.
When detecting unusual signs in accounting - tax data
If revenue, expenses, or invoice stocks between the books and declarations do not match, it is necessary to conduct an immediate review to find the cause (ambiguous documents, confusing supplier tax codes, or complex economic operations that have not been properly processed). Suggested quick check checklist for accounting staff to use.
When the tax authority announces an audit
This is the most important time to fully review, review documents, and complete explanatory documents. The audit service can assist businesses in preparing documents, preparing conclusion reports, and coordinating with tax authorities when authorized.
Service goals and benefits
Ensure accurate and complete tax records
The review service helps to review declarations, books and documents according to current regulations, immediately detect missing documents or errors in declarations so that businesses can make timely adjustments, avoiding legal risks and disputes later.
Help businesses promptly correct errors
When detecting non-deductible expenses or invalid invoices, the service provider will make specific notes and suggest adjustments (recording, preparing revised declarations, supplementing documents), thereby reducing time and effort for the internal accounting department.
Minimize the risk of being charged back taxes and administrative fines
A thorough review will reduce the possibility of being charged back corporate income tax, personal income tax or late payment penalties due to errors; financially, the service fee is often much smaller than the potential fine.
Build trust with partners, investors and banks
Transparent records and audited financial reports in accordance with regulations help businesses easily convince investors in the capital calling round, increase borrowing capacity and enhance brand reputation in the market.
Work content in tax file review
Check tax declarations (VAT, CIT, PIT, contractor tax)
Compare data on the declaration with accounting books and financial reports; check important indicators (taxable revenue, applicable tax rates, deductible taxes) to detect differences or errors before submission.
Check invoices, documents, and economic contracts
Check the validity of invoices (tax code, date, number, and electronic signature if it is an electronic invoice), check the amount, VAT, and check the related contracts/delivery records. Quick checklist suggestion: have corresponding input invoices for all major expenses; sales invoices match the revenue on the books.
Check valid and non-deductible expenses
Review salary expenses, marketing expenses, contractor-related expenses, fixed asset depreciation; identify expenses with insufficient documents or inconsistent with regulations to make recommendations for adjustment.
Review reports on invoice and electronic invoice usage
Check the quantity, issued invoice codes, input/output invoice allocation status; check invoice cancellation/adjustment (if any) to avoid errors when checking with tax authorities.
Assess compliance with preferential policies and tax exemptions (if any)
Check conditions for applying incentives, confirm documents, and application period to ensure that businesses enjoy incentives in accordance with regulations and avoid the risk of collection.
Prepare review report, note errors and recommend adjustments
Summarize findings into a report classified by risk level (high/medium/low), clearly state the action to be taken (e.g., supplement invoice, prepare amended declaration, re-account), and estimate the cost/financial impact if any.
Basic document checklist for a single review
File type | Notes / Examples |
VAT/CIT/PIT declaration | Submission version and amended declarations (if any) |
Accounting books (general ledger, detailed ledger) | Consolidated reports by account and books by quarter |
Input/Output Invoice | Attached contract, delivery receipt, payment documents |
Economic contracts, minutes | Especially contracts with contractors, property purchases and sales |
Financial reports | Balance sheet, income statement, cash flow statement |
Note:
Complex economic transactions (related purchases and sales, asset transfers, mergers and acquisitions) are often a major source of errors; during the review, the team will focus on examining these items more closely and make recommendations in accordance with current tax regulations.

The role of internal accounting in the review process
Prepare complete documents and records
Accountants need to provide accounting books (general ledger, detailed ledger), quarterly invoice list, related contracts and payment documents for PMH to review effectively.
Provide timely and accurate data
To shorten the review time, internal accountants should prepare electronic data (Excel files, exported accounting software data) in the format required by PMH, with instructions if there are special operations.
Coordinate with the service unit to correct errors
Internal accountants are responsible for making corrections as instructed, providing additional documentation, and confirming the processed steps. This cooperation helps complete the process faster and ensures that the accounting books are consistent with the financial statements.
Risks of not reviewing tax records
Accumulated errors lead to large fines and collections
Small errors (missing invoices, incorrect account entries, insufficient supporting documents for expenses) will accumulate over time and can lead to multiple tax periods or administrative fines. Financially, fines and collections are often much larger than the cost of a timely review service.
Waste of time and resources for explanation
When the tax authority conducts an audit, the business must spend a lot of time of accounting and management staff to collect documents and explain; this disrupts business operations and increases operating costs.
Impact on reputation with partners, investors and banks
Unclear records or many problems in the books reduce the trust of partners and investors; this can cause difficulties when raising capital, negotiating contracts or borrowing from banks.
Common administrative penalties
Penalty for late submission of tax declaration
Usually applied as a percentage of the tax payable or the penalty level according to the Decree/Circular; businesses need to check current regulations to know the specific level.
Penalties for false, incomplete, or dishonest declarations
Under-declaring revenue, falsifying expenses, or presenting false information can all result in fines depending on the act; if there are signs of fraud, the business can be handled more severely according to the law.
Tax collection and late payment penalty
When the tax authority discovers errors leading to a shortage of tax payable, the enterprise will be charged the missing tax and will also be subject to late payment penalties calculated daily/monthly according to regulations.
Penalties according to behavior
Detailed penalties are specified in the current Decree/Circular; when needing to give specific figures, businesses should refer to updated legal documents or ask tax law experts for accurate basis.
Advice when receiving an inspection/audit notice from the tax authority
Immediately upon receiving the notice, the enterprise should (1) summon the accounting staff to gather documents according to the required list, (2) contact the tax review service/lawyer to quickly review the risk points and prepare the explanatory documents, (3) if necessary, authorize the representative service unit to work with the authority (in the form of legal authorization) to reduce the workload for the internal department.
