Vietnamese companies must perform dozens of periodic obligations each year: tax declarations, financial report filings, social insurance payments, labor reports, license renewals, information disclosure… Each obligation has its own deadline, form, and receiving authority; missing just one milestone can lead to administrative sanctions, late-payment interest, or lost benefits (such as tax incentives). A legal compliance calendar helps companies fully list obligation milestones in the year, assign responsible persons, and track completion status — instead of depending on a few individuals’ memory.

What a legal compliance calendar is and why Vietnamese companies need one
A legal compliance calendar is a consolidated table of all the company’s periodic legal obligations in a year (and following years), arranged by time, stating the work content, deadline, receiving authority, responsible person, and implementation status. Unlike a one-time checklist, the compliance calendar is a living tool — updated when laws change, when the company develops new business lines, or when the organizational structure changes.
Vietnamese companies need a compliance calendar for three reasons. First, the obligation system is scattered across many laws, with no single document listing them all. Second, after administrative unit reorganizations and state apparatus changes, agency names and receiving competence have changed a lot, which companies update slowly. Third, sanctions for late or missing obligations are increasingly strictly applied — “not knowing” is not a ground for exemption.
Periodic obligations on enterprise registration
Obligations tied to the company’s legal personality: notifying changes to enterprise registration content when changes occur (name, head office address, charter capital, business lines, legal representative, members/shareholders) within statutory deadlines from the change date; disclosing changes on the National Business Registration Portal; keeping and updating the member/shareholder register and charter; holding the annual General Meeting of Shareholders for joint stock companies.
Under Decree 168/2025/ND-CP on enterprise registration, many procedures have been digitized and shortened, but document accuracy requirements are undiminished. The compliance calendar must state which procedure each change type corresponds to, where to file, and how long the deadline is — because each change type has a different process, no single template fits all.
Obligations on tax, invoicing, and financial reports
This is the densest obligation group: monthly or quarterly declarations of value-added tax and personal income tax; annual corporate income tax and personal income tax finalization; annual financial report filing; using e-invoices as prescribed; and industry-specific obligations (contractor tax, resource tax…). Each tax type has its own declaration period, filing deadline, and payment deadline — confusing the periods is a common error.
Beyond periodic obligations, companies should add non-periodic but important milestones to the calendar: tax refund filing deadlines, deadlines for explanations when tax authorities request, complaint prescription against sanction decisions. Lawyers in ongoing legal retainer packages often coordinate with accountants to reconcile the tax calendar with the general legal calendar, avoiding each department tracking its own way.
Obligations on labor, insurance, and wages
Obligations to employees and labor management authorities include: monthly payment of social, health, and unemployment insurance at the right level and on time; periodic labor usage reports; registering internal labor regulations and updating when amended; building salary scales, consulting the grassroots employee representative organization, and publicly posting at the workplace; implementing occupational safety and hygiene obligations; and for companies with foreigners — tracking work permit, visa, and temporary residence expiry.
Note: insurance obligations tie to actual wages with heavy sanctions for evasion or late payment — including interest and possible criminal handling in serious cases under the Penal Code. The compliance calendar should separate HR obligations (records, reports) from finance obligations (withholding and remittance) so responsibilities are not shifted.

Obligations on investment, land, and specialized licenses
For companies with investment projects: periodic reports on investment project implementation under the Investment Law 143/2025/QH15; tracking the investment registration certificate’s validity and incentives. For land-using companies: paying land rent and land use tax on time; tracking land lease terms and renewal conditions. For conditional business lines: tracking each sub-license’s validity (food safety, fire protection, environment, advertising…) and periodic inspection and assessment schedules.
This group is characteristically scattered by project, location, and license — easily missed when companies expand. A company with three branches in three provinces may need to track three different license calendars. This is why the compliance calendar should be organized as a “location × license” matrix rather than one generic list.
How to build and operate a compliance calendar in the company
Step one is inventory: listing all current obligations based on company type, business lines, workforce size, operating locations, and existing licenses. Lawyers usually support this step with an overall review, because self-inventory easily misses obligations the company doesn’t know it has.
Step two is standardization: each obligation recorded with fields — obligation name, legal basis, period (monthly/quarterly/yearly), specific due date, receiving authority, form, primary responsible person, and supervisor. Step three is operation: setting reminders before deadlines (at least 7–15 days depending on complexity), updating completion status, and holding quarterly review meetings. Step four is updating: whenever laws change or the company changes (new business lines, new branches), the calendar must be re-reviewed. Coordination among legal, finance, HR, and operations is the condition for the compliance calendar to be truly implemented rather than staying on paper.
Risks of missing compliance milestones
The most direct consequence is administrative sanctions and late-payment interest — many fines accrue daily, so the later the discovery, the higher the cost. The second consequence is lost benefits: overdue tax refund filings, overdue license renewals, or disqualification from incentives for failing reporting obligations.
The third consequence, less noticed, is compliance reputation. Companies with repeated administrative violations get classified as high-risk, face more frequent inspections, and struggle with procedures (investment adjustments, incentive applications, bidding). A well-operated compliance calendar not only avoids fines but builds a clean compliance record — an intangible asset when the company prepares for M&A or fundraising.
When to contact a lawyer
Companies should have lawyers set up a compliance calendar when newly established, when expanding business lines or locations, after being sanctioned (for comprehensive review to avoid repeat offenses), or when changing compliance personnel. Additionally, whenever new legal documents affect their industry, companies should re-review the calendar to add or adjust obligations.

Frequently asked questions
How does a compliance calendar differ from a year-end checklist?
A year-end checklist is a one-time to-do list at a fixed time; a compliance calendar is a year-round operating tool covering all monthly, quarterly, yearly deadlines and non-periodic milestones. Companies need both: the calendar to miss nothing day-to-day, the year-end checklist for overall review.
Do small companies with few obligations need a compliance calendar?
Yes, but at a simple level. Even household businesses or companies with a few staff have tax, invoicing, insurance (if employees), and business registration obligations. A one-page calendar suffices, as long as it is complete and someone is responsible for tracking.
Who should own the compliance calendar in the company?
It depends on size: small companies may assign it to the accountant or the director’s assistant as an extra duty; medium companies should have a legal or compliance officer; groups need a dedicated compliance department. The general principle: the owner must have authority to require information from departments and report directly to management.
How to update the compliance calendar when laws change?
Whenever new documents affect the company’s industry, review three questions: any new obligations arising, any changes to old deadlines or forms, any changes to receiving authorities. In retainer packages, FLAT LAW FIRM lawyers proactively send legal update alerts to clients instead of waiting to be asked.
What to do if a tax reporting period is missed?
File supplementarily immediately and calculate late-payment interest (if tax is payable). Voluntary remediation before detection is usually considered for mitigation when sanctioned. More importantly, find the root cause of the miss — forgetfulness, no responsible person, or unawareness of the obligation — to fix it fundamentally in the compliance calendar.
