At tongcucthue.info, we understand how overwhelming Vietnam’s tax system can be—especially for individuals, freelancers, startups, and even seasoned business owners. That’s why we built this platform: to provide an unofficial yet reliable source of tax-related knowledge, practical tools, and real-world guidance tailored to your everyday needs.
We are not affiliated with the General Department of Taxation or any governmental authority. Instead, we serve as a bridge to help you understand tax obligations, stay compliant, and avoid common mistakes—without the technical jargon. Whether you’re trying to file your first personal income tax return or navigating complex VAT invoices, tongcucthue.info is your go-to destination.
Let’s make tax management more approachable. Together.
About tongcucthue.info
tongcucthue.info is an independent platform created with the mission to simplify the tax experience for individuals and businesses across Vietnam. We know that dealing with taxes can be frustrating, especially when you’re faced with technical terms, outdated instructions, and unclear processes. That’s where we step in.
This website is not an official government site. We are not operated by the General Department of Taxation (Tổng Cục Thuế) or any affiliated organization. Instead, we act as an informational support hub—designed to guide you through Vietnam’s tax procedures using easy-to-understand language, interactive tools, and up-to-date resources.
Why We Exist
Tax literacy in Vietnam is still evolving. Many individuals and even small businesses lack access to clear, practical, and localized tax guidance. Official documents can be lengthy, full of legal language, and not always user-friendly. As a result, people often make costly mistakes—missing deadlines, underreporting income, or misunderstanding their responsibilities.
tongcucthue.info was born to fill this gap. We aim to empower Vietnamese taxpayers with knowledge, not just instructions. We want users to understand the “why” behind the “how”, and to feel confident in handling their own tax affairs.
Who Should Use This Site?
- Freelancers and gig workers: If you earn income from platforms like Upwork, Fiverr, or local jobs but don’t know how to declare it, we have guides made just for you.
- Startup founders: Need to register for tax, manage invoices, or learn about corporate income tax (CIT)? We explain everything step-by-step.
- Traditional employees: Even if your company handles taxes, understanding how your personal income tax (PIT) works helps you plan better for the year-end settlement.
- Expats living in Vietnam: Navigating the Vietnamese tax system as a foreigner can be daunting. We provide English-language resources to help you stay compliant.
- Accountants and small business owners: Stay on top of VAT, PIT, licensing fees, and more with our up-to-date tools and insights.
Our Philosophy
We believe in the power of knowledge. Taxes don’t have to be scary or confusing. When presented in a clear and friendly manner, tax compliance becomes not just easier—but empowering. We take pride in turning complex tax laws into digestible content that you can understand and apply in real life.
From students to CEOs, we’re here for everyone who wants to do their taxes right—without the headache.
And remember, while we’re here to support you, official tax matters should still be verified through the General Department of Taxation at gdt.gov.vn.
Key Services and Tools at tongcucthue.info
At tongcucthue.info, our goal is not just to explain Vietnam’s tax regulations but also to empower users through practical tools and utilities. Whether you’re looking to check your tax code, calculate personal income tax, or download official tax forms, we’ve got you covered. Below are some of the essential services and tools available on our platform.
1. Tax Identification Number (TIN) Lookup
Do you know your Tax Identification Number (Mã số thuế)? Many individuals don’t realize they already have one. Whether you’re working as an employee or a freelancer, a TIN is essential for declaring income and tracking tax obligations.
Our TIN Lookup Tool allows you to check your tax ID using just your full name and ID card (CMND/CCCD). We pull real-time data from reliable sources and present it clearly, so you don’t have to navigate complicated government portals.
- Search by Name & ID: Just enter your name and national ID to check if you already have a registered TIN.
- Business Lookup: Check the TIN and status of any registered company in Vietnam.
- Status Checker: See whether your tax code is active, suspended, or deactivated.
2. Tax Filing Guidance (eTax / HTKK / iTaxViewer)
Vietnam’s tax system relies heavily on electronic filing, using platforms like HTKK, iTaxViewer, and eTax (thuedientu.gdt.gov.vn). However, for newcomers, these systems can feel confusing and outdated.
We provide visual, step-by-step tutorials on:
- Installing and using HTKK software to prepare your tax declarations
- How to use iTaxViewer to open XML tax files
- Filing directly on the eTax online portal – including login, upload, and submission steps
Each tutorial includes screenshots, best practices, and troubleshooting tips to help you file taxes without depending on an accountant.
3. Tax Calculators
How much income tax do you owe? Are you eligible for any deductions?
We provide simple, user-friendly calculators for:
- Personal Income Tax (PIT): Calculate your tax based on Vietnam’s progressive tax rates.
- Business License Tax: See how much you need to pay annually depending on your capital or business size.
- Late Payment Penalty Calculator: Estimate fines and interest if you missed a deadline.
Our calculators are constantly updated with the latest tax brackets and deduction policies to ensure accuracy.
4. Downloadable Templates and Forms
Need to file a paper return or prepare documents for your accountant? We offer downloadable, editable templates in Excel and Word formats:
- Form 05-QTT-TNCN (Annual PIT Settlement)
- Form 01/GTGT (VAT Return)
- Business License Tax Declaration Form
- Declaration of Independent Income (for freelancers and part-timers)
Each download comes with an explanation of how to fill it out correctly, including definitions of fields and common errors to avoid.
5. Tax Deadline Tracker
Never miss a due date again! Our built-in calendar reminds you of:
- Quarterly tax payment dates for individuals and businesses
- Deadline for annual PIT and CIT finalization
- Important updates and changes in filing schedules (especially during COVID/post-COVID extensions)
You can even subscribe to our email reminders or sync the tax calendar to your Google Calendar or Outlook.
6. Beginner’s Corner

Step-by-Step Tax Filing Guide in Vietnam
Filing taxes in Vietnam doesn’t have to be complicated. Whether you’re a salaried employee, a small business owner, a freelancer, or a foreigner working in Vietnam, this step-by-step guide will walk you through the process of declaring and paying taxes with confidence.
1. Understand Your Taxpayer Category
Before filing any tax, you need to identify your tax status. Are you an employee? A self-employed individual? A business entity?
- Personal income tax (PIT): Applied to individuals earning income from salaries, freelancing, rental property, etc.
- Corporate income tax (CIT): Applied to companies and organizations on profits from business activities.
- Value-added tax (VAT): Required for businesses and service providers who issue invoices.
- Business license tax: An annual fee based on business capital or revenue.
Once you determine your category, it’s easier to know what forms and processes apply to you.
2. Collect the Necessary Documents
Tax filing in Vietnam often requires a number of supporting documents, including:
- ID card (for individuals) or business license (for companies)
- Salary slips or income statements
- Bank account details for tax payment
- Invoices and contracts (for freelancers and businesses)
It’s important to keep digital and physical copies organized by quarter and year to simplify the declaration process.
3. Register or Verify Your Tax Identification Number (TIN)
If you haven’t already, make sure you have a registered TIN (mã số thuế). You can check this using our TIN Lookup Tool or register via the local tax office or your company’s HR department.
4. Install and Use the Required Software
Vietnam’s tax system requires the use of several government software tools, including:
- HTKK: Used to prepare tax declaration forms offline. Available on Windows only.
- iTaxViewer: Allows you to view and validate tax declaration XML files before submission.
- Thuedientu.gdt.gov.vn: The official eTax portal where you log in to submit tax forms and pay online.
Don’t worry—we provide complete installation and usage guides with screenshots and downloadable links.
5. Declare Your Income
5.1. For Individuals (PIT)
If you’re an employee, your company usually withholds and declares your PIT monthly. However, you still need to finalize your annual PIT at year-end (called “quyết toán thuế”).
If you’re a freelancer, you must self-declare income on a monthly or quarterly basis depending on your revenue. You’ll use forms like:
- Form 02/KK-TNCN for monthly declarations
- Form 05/QTT-TNCN for annual finalization
Tax rates follow the progressive scale (from 5% to 35%) based on income brackets. Use our online calculator to determine your tax liability.
5.2. For Businesses (CIT, VAT)
Businesses must submit VAT and CIT declarations. The process includes:
- Filling out Form 01/GTGT for VAT declaration
- Submitting Form 03/TNDN for quarterly CIT prepayment
- Filing an annual CIT finalization using Form 03/TNDN-BQT
You’ll also need to upload invoice summaries and maintain proper accounting records.
6. Submit Your Tax Declaration
Once you’ve prepared the XML files using HTKK, validate them with iTaxViewer, then log into https://thuedientu.gdt.gov.vn to submit. Here’s how:
- Log in using your digital signature (USB token) or username/password.
- Select the appropriate tax form and upload your file.
- Wait for a confirmation message or error report.
If everything checks out, you’ll receive an electronic acknowledgment of receipt. Print and save this for future reference.
7. Pay Your Taxes
After submitting your tax forms, it’s time to pay. This can be done through:
- Online banking (Internet banking/mobile apps)
- Direct transfer to the State Treasury account (with correct codes)
- Paying at authorized tax agents or banks
Use the payment reference code provided after submission to ensure it’s correctly credited.
8. Track Your Filing and Payment Status
On the eTax portal, you can track your filing history, see which declarations have been accepted, and check whether your payments have been confirmed.
We recommend printing or saving copies of:
- Declaration submission receipts
- Bank payment receipts or screenshots
- System notifications from the GDT portal
9. Annual Finalization (Quyết Toán)
At the end of each fiscal year (usually by March 31st), individuals and businesses must finalize their tax obligations. This step ensures that any overpaid or underpaid taxes are settled correctly.
For employees with multiple income sources, you’ll need to compile all income statements and recalculate your annual tax liability. You may be eligible for tax refunds if too much was withheld.
10. Fixing Errors or Filing Late?
If you discover mistakes in your filing or miss a deadline, don’t panic. You can file a supplementary declaration using the same form, but mark it as “Điều chỉnh” (amended). Depending on the case, you may need to pay penalties or late interest.
Our Penalty Calculator Tool helps estimate how much you might owe and guides you through fixing the issue.
—
Final Tips: Always double-check your entries before submitting. Back up your files and receipts, and consult with a licensed tax advisor if you’re unsure. While tongcucthue.info helps you understand the process, we recommend verifying complex issues with your local tax office.
Frequently Asked Questions (FAQs)
Taxes can be confusing, especially when you’re just starting out. Here are the most commonly asked questions we receive from users across Vietnam — along with clear, easy-to-understand answers.
1. What is a Tax Identification Number (TIN) and how do I get one?
A TIN, or Mã số thuế (MST), is a unique number issued to individuals and organizations for tax purposes. If you’ve ever worked as an employee or freelancer, chances are you already have one.
You can check your TIN using our free lookup tool. If you don’t have one yet, you can register through your local tax office or online via your employer or business registration system.
2. I’m a freelancer. Do I need to pay taxes?
Yes. If you’re earning income from freelance gigs, online jobs, or services — whether from local or international clients — you’re required to declare and pay taxes in Vietnam.
Freelancers typically pay personal income tax (PIT) based on total revenue and allowable deductions. We offer a full guide just for freelancers, including templates and tips for quarterly filing.
3. I only work part-time or make money online. Do I still have to file taxes?
Yes. The source or type of income doesn’t exempt you from tax responsibility. Income from YouTube, TikTok, online tutoring, or dropshipping all count as taxable income.
If your income is irregular or under a certain threshold, you may qualify for simplified declaration or partial exemption. Check our Income Thresholds Guide for more details.
4. My tax code is deactivated. What should I do?
A deactivated TIN usually happens if your business license is canceled or you haven’t filed taxes in a long time. To reactivate it, you need to visit your local tax office or submit a formal reactivation request.
You can check the status of your TIN anytime using our Status Checker Tool.
5. I’ve never filed taxes before. Will I get penalized?
Not necessarily. If you were not legally required to file taxes in the past (e.g. income was below the taxable limit), you won’t face any penalty.
However, if you earned taxable income and didn’t declare it, you may be subject to penalties and late fees. It’s best to start now and get up to date. Our Late Penalty Calculator can help you estimate what you owe.
6. I lost my login to the eTax portal. How do I recover it?
If you’ve lost your username or password to thuedientu.gdt.gov.vn, you can:
- Use the “Forgot Password” feature on the login page
- Contact your local tax office for manual reset
- If you use a digital signature, contact the certificate provider for credential recovery
7. How do I get a tax refund?
If you’ve overpaid your personal income tax (usually due to excess monthly withholding by your employer), you can apply for a refund during the annual tax finalization (quyết toán).
You’ll need to submit supporting documents like income slips, Form 05/QTT-TNCN, and a bank account number. Refunds are usually processed within 30–60 days.
8. What’s the deadline for submitting my annual tax return?
For individuals: By March 31st of the following tax year (e.g. for 2024 income, the deadline is March 31st, 2025). For businesses: It varies by tax type, but generally also March 31st.
We publish an updated Tax Calendar every year so you never miss a deadline.
9. Can I declare and pay tax without a business license?
Yes. Individuals who earn income independently can still declare tax under the “individual with income from business activities” model. You don’t need to open a company — just register your income source with the tax office.
10. I’m a foreigner working in Vietnam. Do I need to pay taxes?
If you stay in Vietnam for over 183 days in a year or have a permanent residence here, you are considered a resident for tax purposes and must pay personal income tax on global income.
If you’re a non-resident (short-term visitor), you’re still taxed on income earned in Vietnam, usually at a flat 20% rate.
We offer a full guide for expats and foreigners to help navigate the PIT system here.
11. Can I pay taxes using Momo or ZaloPay?
Yes! Many tax offices now accept tax payments via QR code, bank transfer, or e-wallets like Momo, ZaloPay, or Viettel Money. Make sure to enter the correct reference code provided in your tax declaration form.
12. What if I make a mistake in my tax return?
You can file a corrected declaration (called “Tờ khai bổ sung”). Make sure to clearly state that it’s an amended form, and pay any additional taxes or fines if needed.
13. I earn money from online betting sites like F8BET. Do I need to declare this income?
Yes. Any income you earn — whether from traditional jobs, freelance work, or online platforms like F8BET — is subject to personal income tax if it exceeds the legal threshold.
Gambling winnings may fall under irregular income, and depending on how they’re paid out, you may be required to declare them. For more information, see our Online Income Guide.
