VAT Return Online in Bangladesh: A Complete Step-by-Step Filing Guide
Filing VAT returns is a monthly obligation that every VAT-registered business in Bangladesh must fulfil — accurately, completely, and on time. Since the National Board of Revenue (NBR) introduced its online VAT return filing system, the process has become more streamlined, transparent, and digitally enforced. Yet for many business owners and finance teams, navigating the VAT Online portal for the first time — or managing it consistently month after month — remains a source of confusion and anxiety.
Whether you’re a first-time filer or a business looking to tighten up your compliance routine, this guide will walk you through everything you need to know about VAT return online filing in Bangladesh — from system registration to submission and payment.
And if you’d prefer to have seasoned professionals handle the entire process for you, SAM & Associates has been providing expert VAT compliance services across Bangladesh since 2013.
What Is an Online VAT Return in Bangladesh?
A VAT return is a formal declaration submitted to the NBR by a VAT-registered business, summarizing:
- Total sales (output VAT collected)
- Total purchases (input VAT paid)
- Net VAT payable or refundable for the period
- Supplementary duty, if applicable
In Bangladesh, the standard VAT return form is Mushak 9.1, and it must be submitted every month — regardless of whether any VAT is due or any transactions occurred during the period.
The VAT Online portal (vat.gov.bd), developed and maintained by the NBR, is the official digital platform through which all VAT-registered businesses must submit their returns. Since the rollout of the VAT and Supplementary Duty Act 2012, online filing has become the dominant and increasingly mandatory mode of submission for most categories of taxpayers.
📌 SAM & Associates offers complete Tax Consultancy and VAT Compliance Services for businesses across Bangladesh — including full management of monthly online VAT returns.
Why Filing VAT Returns Online Matters in Bangladesh
A Shift Toward Digital Compliance
The NBR has been progressively expanding digital tax administration infrastructure — from the iBAS++ integrated financial management system to the dedicated VAT Online portal. For businesses, this means:
- Greater transparency — your filing history is digitally recorded and accessible to auditors
- Reduced paperwork — no need to physically visit the VAT Commissionerate for routine filings
- Faster processing — returns and payments are acknowledged instantly
- Stricter enforcement — late or missing filings are automatically flagged in the system
Legal Obligation and Penalties
Under the VAT and Supplementary Duty Act 2012, filing Mushak 9.1 monthly is a statutory requirement for all BIN holders. The consequences of non-compliance include:
| Violation | Consequence |
| Late submission of Mushak 9.1 | Penalty + interest on outstanding VAT |
| Non-submission of return | Penalty up to BDT 10,000 per return |
| Incorrect return (understating VAT) | Penalty + interest + potential audit |
| Failure to pay net VAT due | Interest at prescribed rate per month |
| Repeated non-compliance | Escalated enforcement and possible BIN cancellation |
The stakes are real — which is why businesses benefit enormously from having professional VAT expertise on their side.
Who Is Required to File VAT Returns Online in Bangladesh?
Any business that has obtained a Business Identification Number (BIN) from the NBR is required to file VAT returns. This includes:
- Manufacturing companies
- Trading businesses (importers, exporters, wholesalers, retailers at VAT-applicable tiers)
- Service providers (IT firms, consultancies, logistics, construction, etc.)
- Importers of goods
- Businesses registered under the turnover tax scheme (filing different forms)
Even if a business has zero transactions in a given month, a nil return (Mushak 9.1 showing zero) must still be filed by the deadline.
What You Need Before Filing VAT Return Online
Before logging into the VAT Online portal, make sure the following are in order:
Prerequisites Checklist
| Requirement | Details |
| Active BIN | Your 9-digit Business Identification Number from NBR |
| VAT Online Portal Credentials | Username and password for vat.gov.bd |
| Monthly Sales Records | All Mushak 6.3 invoices issued during the month |
| Monthly Purchase Records | All Mushak 6.3 invoices received during the month |
| Input Tax Credit Register | Reconciled list of eligible input VAT claims |
| Bank Payment Information | For depositing net VAT payable via treasury challan |
| Supplementary Duty Records | If applicable to your business sector |
Maintaining accurate and organized records throughout the month is the single most important factor in making online VAT return filing smooth and error-free.
Our Accounting Services ensure your books are consistently maintained and VAT-ready every month — so filing is never a last-minute scramble.
Step-by-Step Guide: How to File VAT Return Online in Bangladesh
Here is a detailed walkthrough of the online VAT return filing process using the NBR VAT Online portal.
Step 1: Log In to the NBR VAT Online Portal
- Visit the official portal: https://vat.gov.bd
- Enter your registered BIN and password
- Complete any required CAPTCHA verification
- Access your taxpayer dashboard
If you have not yet registered on the portal, you will need to create an account using your BIN and the details on file with the NBR.
Step 2: Navigate to the Return Filing Section
- From your dashboard, select “Return” or “Mushak 9.1” from the main menu
- Select the tax period you are filing for (month and year)
- The system will load a pre-populated or blank Mushak 9.1 form
Step 3: Enter Output VAT (Sales) Details
In the output section of Mushak 9.1, enter:
- Total value of taxable supplies made during the month
- VAT collected on those supplies (at applicable rates — standard 15%, or sector-specific reduced rates)
- Supplementary duty collected, if applicable
- Any adjustments for debit notes, credit notes, or returns from previous periods
Cross-reference this information with your Mushak 6.3 invoice register to ensure accuracy.
Step 4: Enter Input VAT (Purchase) Details
In the input section, enter:
- Total value of taxable purchases made during the month
- Input VAT paid on those purchases
- Only include purchases for which you hold valid Mushak 6.3 invoices from registered suppliers
- Enter any carry-forward input tax credit from the previous period, if applicable
Critical note: Input tax credit can only be claimed against valid invoices. Incorrect or unverifiable ITC claims are a leading cause of VAT audit triggers.
Step 5: Calculate Net VAT Payable or Refundable
The system will automatically compute:
Net VAT = Output VAT − Input VAT
- If Output VAT > Input VAT: You owe the difference to the government
- If Input VAT > Output VAT: You have a credit that can be carried forward (refunds are subject to NBR approval in most cases)
Review the calculated figures carefully before proceeding.
Step 6: Review and Verify the Return
Before submitting, carefully review:
- All figures entered match your source records
- The correct tax period is selected
- BIN and business name are accurate
- All supplementary duty, if applicable, is correctly reflected
- No fields are left incorrectly blank
This is the most important step — errors discovered after submission require amendment procedures that can be time-consuming.
Step 7: Submit the Return
- Click “Submit” or “File Return” in the portal
- The system will generate a submission acknowledgment with a unique reference number
- Download and save this acknowledgment — it is your proof of timely filing
Step 8: Pay Net VAT Due
If your return shows a net VAT payable:
- Generate a treasury challan through the portal or your bank’s government payment module
- Pay the amount due via designated commercial banks that accept NBR tax payments
- Retain the payment receipt as part of your compliance records
The deadline for both filing and payment is the 15th of the following month. For example, the January return and payment are both due by 15 February.
Step 9: Maintain Records
After filing:
- Archive the submitted Mushak 9.1 return
- Retain all supporting Mushak invoices and purchase records
- Keep records for a minimum of 5 years as required under the VAT and Supplementary Duty Act 2012
VAT Return Filing: Common Errors to Avoid
Even experienced finance teams make mistakes in the monthly filing cycle. Watch out for these:
- Entering output VAT based on collections rather than invoices issued — VAT is due at the point of supply, not payment receipt
- Claiming ITC without a valid Mushak 6.3 invoice — verbal or informal purchase records do not qualify
- Forgetting nil returns — if there were no transactions, a nil Mushak 9.1 must still be filed
- Using the wrong VAT rate — different goods and services attract different rates; misapplication is a common audit finding
- Missing the 15th deadline — consistently late filings attract penalties and put your compliance record at risk
- Not reconciling with your accounting records — discrepancies between your VAT return and financial accounts are major audit triggers

VAT Return Filing: Monthly Compliance Calendar
Use this calendar to stay on track with your monthly VAT obligations:
| Timeline | Action Required |
| 1st–5th of the month | Compile all sales invoices (Mushak 6.3) from the previous month |
| 5th–10th of the month | Compile all purchase invoices and reconcile input VAT |
| 10th–13th of the month | Prepare Mushak 9.1 return and review figures |
| 13th–14th of the month | Final review and verification of return |
| By 15th of the month | Submit Mushak 9.1 online and pay net VAT due |

Following this calendar religiously removes the stress of last-minute filing and significantly reduces the risk of errors.
When Should You Outsource Your VAT Return Filing?
Managing VAT returns in-house is feasible for some businesses — but not all. Consider outsourcing to a professional VAT consultant if:
- Your business handles high transaction volumes that are difficult to reconcile monthly
- You operate in multiple VAT categories with different rates and exemptions
- Your internal team lacks specialist VAT knowledge of Bangladesh’s regulatory framework
- You’ve received penalty notices or audit communications from the NBR
- You want to focus on core business operations rather than compliance administration
- You are expanding your business and need compliance infrastructure to scale with you

Frequently Asked Questions (FAQ)
Q1: What is the deadline for filing VAT returns online in Bangladesh?
A: VAT-registered businesses must submit their monthly Mushak 9.1 return and pay any net VAT due by the 15th of the following month. For example, the VAT return for March must be filed and paid by 15 April. Missing this deadline results in penalties and interest charges.
Q2: Do I need to file a VAT return if I had no transactions during the month?
A: Yes. Even if your business had zero sales or purchases during a given month, you are still required to file a nil Mushak 9.1 return by the 15th deadline. Failure to do so is treated as non-filing and can result in penalties.
Q3: Can I amend a VAT return after it has been submitted online?
A: Yes, the VAT and Supplementary Duty Act 2012 allows for amended returns under specific conditions. However, amendments that reduce VAT liability require NBR approval and may trigger scrutiny. It is always better to get the return right the first time — which is why professional review before submission is strongly recommended.
Q4: What documents do I need to support my online VAT return in Bangladesh?
A: You must maintain and be able to produce: all Mushak 6.3 invoices issued and received during the period, your purchase and sales registers, bank statements reconciled to VAT transactions, treasury challans for VAT payments made, and copies of all submitted Mushak 9.1 returns — all for a minimum retention period of 5 years.
Conclusion
Filing your VAT return online in Bangladesh is a monthly obligation that requires accuracy, timeliness, and a solid understanding of the NBR’s systems and requirements. While the VAT Online portal has made the submission process more accessible, the complexity of input tax credits, Mushak invoice management, and reconciliation means that errors and missed deadlines remain common — and costly.
Whether you choose to manage the process in-house or partner with a professional firm, the key is consistency, precision, and staying ahead of every monthly deadline.
