Complex Calculation Basis for Social Insurance (BHXH, BHYT, BHTN)<\/h2>\n\n\n\n<p>In Vietnam, the contribution rates for social insurance are defined separately for employees and employers,<br>\nand the calculation methods and coverage differ greatly from those in Japan. In addition, the range of <span class=\"swl-marker mark_orange\"><strong>allowances included in the social insurance calculation base<\/strong><\/span><br>\ncan vary from company to company, which is another major practical pain point.<\/p>\n\n\n\n<div class=\"wp-block-group is-style-big_icon_good\"><div class=\"wp-block-group__inner-container\">\n<ul class=\"wp-block-list\">\n<li>The company has not clearly defined which allowances are subject to social insurance and which are not<\/li>\n\n\n\n<li>There is a statutory ceiling amount, but it is not being applied correctly<\/li>\n\n\n\n<li>When the salary structure is revised, the company does not review or update its social insurance calculations<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n<p><strong><span class=\"swl-fz u-fz-l\">Common case:<\/span><\/strong><br>\nAn allowance that should have been excluded from the social insurance base was mistakenly included, resulting in several months of overpayments. The company then had to spend significant time and effort refunding employees and correcting its accounting records.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2. Inconsistent Attendance Data Makes It Hard to Gather the Basics for Payroll<\/h2>\n\n\n\n<p>The starting point for payroll calculation is daily <span class=\"swl-marker mark_orange\"><strong>attendance data<\/strong><\/span>.<br>\nHowever, in practice, the following issues often arise on site:<\/p>\n\n\n\n<div class=\"wp-block-group is-style-big_icon_caution\"><div class=\"wp-block-group__inner-container\">\n<ul class=\"wp-block-list\">\n<li>Different attendance formats by department (a mix of Excel sheets, paper records, and time-clock systems)<\/li>\n\n\n\n<li>Overtime, night work, and work on holidays are reported late and submitted after the fact<\/li>\n\n\n\n<li>Approval workflows are not clearly defined, making it unclear who authorized the final data<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n<p>As a result:<\/p>\n\n\n\n<div class=\"wp-block-group is-style-big_icon_bad\"><div class=\"wp-block-group__inner-container\">\n<ul class=\"wp-block-list\">\n<li>Attendance data is not fully collected until just before the payroll cutoff, forcing staff to work overtime or overnight<\/li>\n\n\n\n<li>After payroll is processed, many correction requests come in, such as \u201cMy overtime was not reflected\u201d<\/li>\n\n\n\n<li>No history of corrections is kept, making it impossible to later trace the basis of calculations<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n<p>The fact that <strong><span class=\"swl-inline-color has-swl-deep-01-color\">attendance formats and rules are not unified<\/span><\/strong> across the company is the starting point for many of these issues.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3. Different Rules for Expatriates and Local Staff<\/h2>\n\n\n\n<p>In many foreign-invested companies, it is common to have a mix of <span class=\"swl-marker mark_orange\"><strong>expatriates from Japan and locally hired staff<\/strong><\/span>.<br>\nThese two groups are treated very differently in terms of payroll, social insurance, and taxation, which makes the calculations more complex.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Item<\/th><th>Expatriates<\/th><th>Local Staff<\/th><\/tr><\/thead><tbody><tr><td>Social Insurance<\/td><td>In some cases, they are covered by Japanese social insurance and exempt from Vietnamese social insurance<\/td><td>Covered by Vietnam\u2019s social insurance schemes (BHXH, BHYT, BHTN)<\/td><\/tr><tr><td>Salary Structure<\/td><td>Japan HQ salary + Vietnam-side salary + housing allowance, etc.<\/td><td>Base salary + various allowances (position, meal, transportation, etc.)<\/td><\/tr><tr><td>Personal Income Tax (PIT)<\/td><td>Taxable income is determined based on the total of Japan-side and Vietnam-side payments<\/td><td>Tax is calculated based on Vietnam-side salary<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Especially for expatriates, it is difficult to determine how much of the \u201cJapan-side payments,\u201d \u201cVietnam-side payments,\u201d and \u201cin-kind benefits (such as company housing)\u201d should be included in the PIT taxable base. If the scheme is poorly designed, it can lead to significant <strong><span class=\"swl-inline-color has-swl-deep-01-color\">tax risks<\/span><\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">4. Errors Easily Occur in Personal Income Tax (PIT) Calculations<\/h2>\n\n\n\n<p>Vietnam\u2019s personal income tax (PIT) is progressive, with multiple tax rates applied depending on income levels.<br>\nThe points where foreign-invested companies often stumble are less about misunderstanding the system itself and more about <span class=\"swl-marker mark_orange\"><strong>gaps in day-to-day operations<\/strong><\/span>.<\/p>\n\n\n\n<div class=\"wp-block-group is-style-big_icon_caution\"><div class=\"wp-block-group__inner-container\">\n<ul class=\"wp-block-list\">\n<li>Registration and updates for dependent deductions (Ng\u01b0\u1eddi ph\u1ee5 thu\u1ed9c) are left entirely to employees<\/li>\n\n\n\n<li>The taxable \/ non-taxable treatment of benefits and allowances is ambiguous and inconsistently applied<\/li>\n\n\n\n<li>Allowances and bonuses paid from Japan are mistakenly omitted from the PIT taxable base<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n<p><strong><span class=\"swl-fz u-fz-l\"><span class=\"swl-inline-color has-swl-deep-01-color\">Important:<\/span><\/span><\/strong><br>\nUnregistered dependents or misclassification of allowances are points that tax auditors frequently flag. If additional tax is levied retroactively in a lump sum, it can also damage the trust relationship between the company and its employees.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">5. Failing to Keep Up with Minimum Wage Revisions, Leading to Retroactive Adjustments<\/h2>\n\n\n\n<p>In Vietnam, minimum wages are set by region, and it is common for them to be <span class=\"swl-marker mark_orange\"><strong>revised almost every year<\/strong><\/span> in line with government decisions.<br>\nWhen the minimum wage is revised, companies should ideally review and adjust the following items:<\/p>\n\n\n\n<div class=\"wp-block-group is-style-big_icon_caution\"><div class=\"wp-block-group__inner-container\">\n<ul class=\"wp-block-list\">\n<li>Base salary levels<\/li>\n\n\n\n<li>Standard amounts used for calculating social insurance<\/li>\n\n\n\n<li>Overtime pay rates<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n<p>However, if companies are slow to catch up with the revised rules or delay internal updates, the following situations can occur:<\/p>\n\n\n\n<div class=\"wp-block-group is-style-big_icon_bad\"><div class=\"wp-block-group__inner-container\">\n<ul class=\"wp-block-list\">\n<li>Employees are paid below the minimum wage for several months<\/li>\n\n\n\n<li>The basis for calculating social insurance contributions remains outdated<\/li>\n\n\n\n<li>The company ultimately needs to handle retroactive adjustments in a lump sum<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n<p>To avoid such outcomes, it is essential to have a framework in which <strong><span class=\"swl-inline-color has-swl-deep-01-color\">not only HR and payroll staff but also management<\/span><\/strong> regularly review information on legal revisions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Is Your Vietnam Payroll Really Under Control? A Simple Checklist<\/h2>\n\n\n\n<p>You can quickly gauge your company\u2019s risk level by checking <strong>how many of the following items you can answer \u201cYes\u201d to<\/strong>:<\/p>\n\n\n\n<div class=\"wp-block-group is-style-big_icon_good\"><div class=\"wp-block-group__inner-container\">\n<ul class=\"wp-block-list is-style-check_list\">\n<li>The company has clearly defined which allowances are subject to social insurance and which are not<\/li>\n\n\n\n<li>Attendance data formats and rules are unified across all departments<\/li>\n\n\n\n<li>The Japan-side and Vietnam-side salaries for expatriates\u2014and their taxable ranges\u2014are clearly organized<\/li>\n\n\n\n<li>Dependent deduction registrations and updates are reliably carried out, for example at least once a year<\/li>\n\n\n\n<li>Minimum wage revisions are checked every year and reflected in salaries and social insurance calculations<\/li>\n\n\n\n<li>The logic and history of payroll calculations can be traced by people other than the primary person in charge<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n<p>If you have many \u201cNo\u201d answers, there may be room for improvement in both your policies and your operational processes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion: Standardizing Operations Is Just as Important as Understanding the System<\/h2>\n\n\n\n<p>The reason payroll processing in Vietnam is difficult is not only because the system itself is complex.<br>\nIn reality, issues such as the following often cause many of the mistakes and problems:<\/p>\n\n\n\n<div class=\"wp-block-group is-style-big_icon_point\"><div class=\"wp-block-group__inner-container\">\n<ul class=\"wp-block-list\">\n<li>Attendance and allowance rules differ from department to department<\/li>\n\n\n\n<li>Differences between expatriates and local staff are not clearly organized<\/li>\n\n\n\n<li>Know-how is concentrated in specific individuals, making operations highly person-dependent<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n<p>These kinds of <strong><span class=\"swl-inline-color has-swl-deep-01-color\">operational issues<\/span><\/strong> are behind many of the errors and troubles.<br>\nTo stabilize payroll processing at your Vietnam office, you need not only a <strong><span class=\"swl-inline-color has-swl-deep-01-color\">correct understanding of the system<\/span><\/strong>, but also:<br>\n<strong>\u201c<span class=\"swl-inline-color has-swl-deep-01-color\">Centralized management of data and rules<\/span>\u201d<\/strong>
