Where to download HTKK 5.7.5 software and the correct steps to follow.
Official address to download HTKK 5.7.5 software
Taxpayers (organizations and individuals) can download the application's installation package and user manual directly from the tax authority's electronic portal. The only authorized source for the official installation package is the website at http://www.gdt.gov.vn/wps/portal/home/hotrokekhai.
The solution from MAN – Master Accountant Network recommends that businesses absolutely avoid downloading installation files from forums or websites floating around on the internet. Files from unknown sources may contain malware, leak confidential financial data, or distort the XML data structure when submitted to tax authorities. If encountering difficulties during the download or installation process, accountants should contact the support department of their respective tax office directly.
Installation and update process for the application to version 5.7.5
The software update process requires careful attention to avoid losing tax return data stored on older versions. Starting August 17, 2026, when preparing tax returns related to the upgrade, taxpayers must use the declaration functions in this new version. Before installation, accountants need to back up all data from the old system to protect the database.
After downloading the installer from the official source, users extract the files and run the installer with the highest administrator privileges on the computer. The automatic installation process will detect the old version and upgrade system files without losing existing statement data. From MAN's perspective, businesses should assign an accounting IT staff member to be responsible for checking all network connections and digital signatures after a successful upgrade.
Details of the upgrades and business changes in version 5.7.5
Seven additional sets of financial statements have been added in accordance with the new regulations.
Version 5.7.5 updates the features for importing and exporting XML, exporting to Excel, downloading XML, and printing for 7 sets of financial reports to comply with new legal regulations. Specifically, this includes: Circular 71/2024/TT-BTC Guidelines on accounting procedures for cooperatives., Circular 132/2018/TT-BTC and Circular 58/2026/TT-BTC Regarding accounting regulations for micro-enterprises, the application integrates reporting requirements according to Circular 41/2022/TT-BTC applicable to social and charitable activities, along with reporting requirements according to Circular 99/2025/TT-BTC for full annual and interim reports, and summarized interim reports.
This integration allows businesses to perform data entry, error checking, and XML file export on a single, unified interface. Experts at MAN, with 30 years of experience, believe that standardizing financial reporting templates minimizes technical errors. Businesses need to review their business activities to select the appropriate set of financial reports in accordance with current legal regulations.
Update the calculation formulas in the tax return for household businesses and individual business owners.
The tax declaration form for household businesses and individual businesses according to form No. 01/CNKD under Circular 50/2026/TT-BTC has been updated with detailed calculation formulas in section A, item [14]. This formula is specifically classified according to each group of business sectors to ensure transparency in financial obligations:
- Distribution, supply of goods: [14a] = [(11a) – (12a) – (13a)] multiplied by 1% minus the total column (6) of the business location and tax-paying industry group with the location code selected for declaration on Appendix 204.
- Services, construction without material procurement: [14b] = [(11b) – (12b) – (13b)] multiplied by 5% minus the total column (6) corresponding on Appendix 204.
- Rental activities excluding real estate: [14c] = [(11c) – (12c) – (13c)] multiplied by 5% minus the total of column (6) corresponding on Appendix 204.
- Production, transportation, services related to goods, construction with material procurement: [14d] = [(11d) – (12d) – (13d)] multiplied by 3% minus the total column (6) corresponding on Appendix 204.
- Activities providing digital information content products about entertainment, video games, digital movies, digital photos, digital music, digital advertising: [14e] = [(11e) – (12e) – (13e)] multiplied by 5% minus the total of column (6) corresponding on Appendix 204.
- Other business activities: [14f] = [(11f) – (12f) – (13f)] multiplied by 2% minus the total of column (6) corresponding on Appendix 204.
Accountants need to enter the correct industry code so that the application can automatically reconcile data, avoiding manual calculations that can lead to discrepancies in the amount of tax payable. Early tax risk management for household businesses is fundamental to avoiding tax assessment decisions from the authorities.
New points regarding the personal declaration form for direct declaration and the appendix for value-added tax reduction.
The updated version of the application for the tax declaration form 02KK-TNCN, submitted directly by individuals according to Circular 80/2021/TT-BTC, allows the output of the kyKKhaiTuNgay tag, which is the first day of the From month of declaration. This technical change helps the tax authority's system accurately identify the tax period in which individuals fulfill their financial obligations.
In addition, the appendix on value-added tax reduction according to Resolution No. 204/2025/QH15 is attached to the declaration form. VAT Form 01/GTGT has been supplemented with a strict control feature. The function of uploading the Excel statement to the application performs data verification at indicators (3), (4) section I and indicator (3) section II on Appendix 142/2024/QH15, which are not allowed to be negative. If there is a discrepancy, the system will immediately issue a red warning so that the accountant can make timely adjustments before submission.
Updated excise tax rates and the 5-tier progressive personal income tax schedule.
The Special Consumption Tax Declaration Form No. 01/TTĐB under Decree 373 has been updated with new tax rates effective from July 1, 2026. Specifically, the tax rate for alcoholic beverages with an alcohol content of 20 degrees or higher has been updated to 65%, for imported beer sold domestically it has been updated to 65%, and for imported spirits with an alcohol content below 20 degrees sold domestically it has been updated to 35%.
For the personal income tax final settlement declaration form No. 05/QTT-TNCN according to Circular 80/2021/TT-BTC, from the 2026 settlement period, the application updates indicator [24] in Appendix 05-1/BK-TNCN to meet the new progressive tax schedule consisting of 5 brackets. The new tax schedule divides taxable income by year and by month as follows:
| Tax rates | Taxable income per year (million VND) | Taxable income per month (million VND) | Percentage tax rate |
| 1 | Up to 120 | Up to 10 | 5% |
| 2 | Over 120 to 360 | Between 10 and 30 | 10% |
| 3 | Over 360 to 720 | Between 30 and 60 | 20% |
| 4 | Between 720 and 1,200 | Between 60 and 100 | 30% |
| 5 | Over 1,200 | Over 100 | 35% |
This update helps the software automatically and accurately calculate the amount of personal income tax payable or refundable for each employee in the business. MAN's tax settlement service closely monitors these tax rate changes to ensure optimal benefits for the personnel at our clients' businesses.
The legal basis and authority of the tax administration agency are governed by Article 19 of the 2019 Law on Tax Administration.
A compilation of core legal documents integrated into the software.
The release of version 5.7.5 is based on a solid legal foundation derived from regulatory documents issued by the Ministry of Finance and the Government. The list of key documents includes Law No. 38/2019/QH14 on Tax Administration, Resolution No. 204/2025/QH15 on Value Added Tax reduction, and a series of circulars on corporate accounting regulations. Systematizing these documents into the software helps businesses correctly fulfill their financial obligations without having to consult multiple sources.
The table below summarizes the main legal documents integrated and processed in the latest version of the HTKK application:
| Document number | Date of issuance | Area of application | Main content integrated into the software |
| Circular 58/2026/TT-BTC | 25/05/2026 | Business accounting | Accounting guidelines for micro-enterprises |
| Circular 132/2018/TT-BTC | 28/12/2018 | Business accounting | Accounting guidelines for micro-enterprises |

Details of the current authority of the tax administration agency.
When performing their duties, tax authorities have full powers as stipulated in Article 19 of the 2019 Tax Administration Law to ensure financial discipline. Specifically, tax authorities have the right to request taxpayers to provide information and documents related to determining tax obligations, including information on investment value, account numbers and transaction details of accounts opened at commercial banks and other credit institutions, and to explain tax calculation, tax declaration, and tax payment.
The tax authorities have the right to request relevant organizations and individuals to provide information and documents to determine tax obligations and cooperate in law enforcement. Simultaneously, the tax authorities conduct inspections, audits, tax assessments, enforcement actions, penalties, and publicly disclose cases of violations. Furthermore, the tax authorities may apply preventive measures, delegate collection, agree in advance on methods for determining taxable value, purchase domestic and international data for tax management purposes, and pay the costs of delegated collection as prescribed.
MAN's tax consulting service always reminds businesses that strict adherence to the declaration regulations on the HTKK software is a shield protecting businesses from inspections. Transparency in data output from the software is key to building a trusting relationship with state management agencies.
Real-world case study: Addressing data error risks during HTKK software upgrades.
A real-life situation at a medium-sized manufacturing enterprise.
During the August 2026 tax declaration period, Alpha Production and Trading Co., Ltd. installed the HTKK 5.7.5 application to submit the special consumption tax declaration and the appendix for value-added tax reduction. Due to the accounting staff's failure to back up data before overwriting, all data from previous periods' purchase invoice lists were displayed incorrectly. Simultaneously, the incorrect entry of item [14d] for production activities with material procurement resulted in a large discrepancy in tax figures compared to the internal accounting records.
This situation immediately triggered a red alert on the tax authority's receiving system due to discrepancies between the tax return and the supplementary statement. The company's management faced the risk of tax assessment and administrative penalties for late submission of valid tax returns. This was a costly lesson about the importance of controlling technical processes when implementing new versions of tax management software.
In-depth solutions and management lessons from an expert's perspective.
Upon receiving a request for urgent assistance, MAN's team of audit experts was present at the business to diagnose and resolve the issue. The first solution was to restore the backup data file from a secure copy stored independently on the internal server. Next, the experts guided the accounting department in reviewing all calculation formulas for the new items on form 01/CNKD and the special consumption tax return.
After adjusting the data to comply with the regulations in the new circular, the system allowed the export of a clean XML file for submission to the tax authorities on time. Alpha Company avoided tens of millions of dong in administrative fines and maintained its reputation for compliance with tax laws. More than 500 clients have trusted MAN's tax accounting services precisely because of this timely intervention and practical risk management approach.
Expert's perspective: Potential risks and best practices for optimizing tax costs.
Identifying common legal blind spots that businesses face.
The transition to new versions of tax declaration software always involves legal loopholes that can easily lead to errors for businesses. One of the biggest blind spots is the lack of synchronization between internal accounting software and the HTKK application due to the failure to update the chart of accounts in time. When accountants perform automatic data export operations, specific indicators such as the new excise tax rate for alcoholic beverages effective from July 1, 2026, may be overlooked.
According to experts at MAN – Master Accountant Network, with 30 years of experience, businesses should not rely solely on the automated features of accounting software. Finance personnel need to possess critical thinking skills and a thorough understanding of the legal wording to cross-reference actual figures. Proactive cross-checking between tax returns, financial statements, and accounting ledgers is a mandatory process in any professional business.
Strategies for managing risks and optimizing the amount of tax payable legally.
Tax risk management goes beyond simply filing on time; it's also about optimizing cash flow and costs for the business. Businesses need to establish a closed-loop internal control process, from electronic invoicing to tax declaration on the latest version of the HTKK application. Any changes in tax rates, progressive tax schedules, or tax reduction appendices must be updated in the accounting department's internal operational manual.
The solutions from MAN – Master Accountant Network are always geared towards supporting businesses in conducting quarterly financial health reviews. Instead of waiting for tax authorities to audit and discover errors, our experts help businesses self-diagnose and make timely adjustments. Our deep understanding of legal practices in Vietnam allows businesses to focus on developing their core business with peace of mind.
