If you run a registered business in Bangladesh, submitting your VAT return on time is not just a legal obligation — it is a critical part of maintaining your business’s good standing with the National Board of Revenue (NBR). Yet for many business owners, the process of navigating the online VAT system can be confusing, error-prone, and stressful.
This comprehensive guide, prepared by the experts at SAM & Associates, walks you through exactly how to submit a VAT return online in Bangladesh — from registration and eligibility to filing deadlines, common mistakes, and how professional support can make the entire process seamless.
Whether you’re filing for the first time or looking to ensure your existing process is fully compliant, this guide has everything you need.
What Is a VAT Return in Bangladesh?
A VAT return (also known as Mushak-9.1 in Bangladesh) is a formal declaration submitted by a VAT-registered business to the National Board of Revenue (NBR) detailing:
- Total taxable sales and output VAT collected
- Total taxable purchases and input VAT paid
- Net VAT payable to the government (or refundable)
Under the VAT and Supplementary Duty Act 2012, all VAT-registered businesses in Bangladesh are legally required to submit a VAT return on a monthly basis, regardless of whether any transactions occurred during the period.
Key VAT Return Form: Mushak-9.1
The primary return form used for online VAT submission in Bangladesh is Mushak-9.1. This form captures:
- Sales and output tax details
- Purchase and input tax credits
- Supplementary duty (if applicable)
- Adjustments and carry-forward amounts
- Net tax payable
Why Submitting Your VAT Return on Time Matters in Bangladesh
Failing to submit your VAT return correctly and on time carries serious consequences under Bangladeshi law. Here’s why compliance is non-negotiable:
| Risk Factor | Consequence of Non-Compliance |
|---|---|
| Late submission | Monetary penalty per day of delay |
| Incorrect filing | Risk of audit, back-tax demand, and fines |
| Non-submission | Cancellation of VAT registration |
| Misreported input tax | Disallowance of credits + interest charges |
| Repeated violations | Legal prosecution under VAT Act 2012 |
Beyond penalties, timely and accurate VAT filing builds credibility with regulators, simplifies audit processes, and ensures your business can claim legitimate input tax credits — reducing your overall tax burden.

Who Is Required to Submit a VAT Return in Bangladesh?
Not every business is required to file VAT returns. Here is a clear breakdown of VAT registration thresholds and obligations under current NBR rules:
Mandatory VAT Registration (Standard Rate – 15%)
Businesses with annual turnover above BDT 3 crore must register for VAT at the standard 15% rate and submit monthly Mushak-9.1 returns.
Turnover Tax (Small Businesses)
Businesses with annual turnover between BDT 50 lakh and BDT 3 crore may be eligible to pay a flat turnover tax of 4% and are subject to simplified filing requirements.
VAT-Exempt Entities
Certain goods and services listed under the VAT Act are exempt from VAT and do not require standard VAT return filing.
Key takeaway: If your business is VAT-registered at the standard 15% rate, you must submit a VAT return every month — even if your taxable transactions were zero (a “nil return”).
Prerequisites Before You Submit a VAT Return Online
Before you begin filing, ensure you have the following in place:
- Active VAT Registration (BIN): Your Business Identification Number issued by NBR
- Access to the VAT Online System: Login credentials for the NBR VAT portal (vat.gov.bd)
- Completed Mushak Books: Including Mushak-6.1 (purchase register), Mushak-6.2 (sales register), and supporting vouchers
- Bank Payment Receipt: Proof of VAT payment made via treasury challan (if tax is due)
- Previous Return Records: To carry forward any unadjusted input tax credits
How to Submit VAT Return Online in Bangladesh: Step-by-Step
Here is the complete process for submitting your VAT return through the NBR’s online VAT system:
Step 1: Log In to the VAT Online Portal
Visit the official NBR VAT portal at vat.gov.bd and log in using your BIN (Business Identification Number) and registered password.
If you have not yet registered for online access, you will need to complete the e-registration process on the NBR portal first.
Step 2: Navigate to the Return Submission Section
From your dashboard, select “Return” from the main menu, then choose “Mushak-9.1 — VAT Return” from the dropdown list.
Step 3: Select the Tax Period
Choose the relevant tax period (month and year) for which you are submitting the return. Ensure you are filing for the correct period — returns must be submitted by the 15th of the following month.
Step 4: Enter Sales (Output Tax) Details
Input your total taxable sales for the period. This should match your Mushak-6.2 (sales register). The system will automatically calculate the output VAT at the applicable rate (typically 15%).
Step 5: Enter Purchase (Input Tax) Details
Enter your total taxable purchases eligible for input tax credit. This must be supported by valid Mushak-6.3 purchase vouchers from VAT-registered suppliers. The system calculates your allowable input tax credit.
Step 6: Include Supplementary Duty (If Applicable)
If your business deals in goods or services subject to supplementary duty, enter the relevant figures in the supplementary duty section.
Step 7: Calculate Net VAT Payable
The system will automatically compute your net VAT payable as:
Net VAT = Output Tax − Input Tax Credit − Adjustments
If the result is positive, you owe VAT to the government. If negative, you may have an excess input tax credit to carry forward.
Step 8: Pay the VAT Due (If Applicable)
Before finalising the return, pay any outstanding VAT liability via:
- Online banking through the NBR’s integrated payment gateway
- Treasury challan at a designated bank branch
Keep the payment reference number and receipt for your records.
Step 9: Upload Supporting Documents
Attach any required supporting documents, including:
- Summary of Mushak-6.1 and Mushak-6.2 registers
- Treasury challan (proof of payment)
- Any adjustment notices or credit notes
Step 10: Submit and Download Acknowledgement
Review all entered data carefully, then click “Submit.” Upon successful submission, download and save your acknowledgement receipt — this is your legal proof of filing.

| February | 15th March | 15th March |

Common Mistakes to Avoid When Submitting a VAT Return
Even experienced filers make errors that can trigger audits or penalties. Here are the most frequent mistakes to watch for:
- Mismatched figures between the return and Mushak registers
- Claiming input tax on purchases from non-VAT-registered suppliers
- Failing to submit nil returns during months with no transactions
- Incorrect BIN used on purchase vouchers from suppliers
- Missing payment before submission, leading to penalties
- Using outdated forms instead of the current NBR-approved version
- Not retaining documentation for the mandatory 5-year record-keeping period
VAT Return vs. VAT Challan: Key Differences
Many business owners confuse these two documents. Here’s a clear comparison:
| Feature | VAT Return (Mushak-9.1) | VAT Challan (Treasury) |
|---|---|---|
| Purpose | Declares VAT liability for the period | Confirms payment of VAT due |
| Submitted to | NBR via VAT online portal | Bank / NBR payment gateway |
| Frequency | Monthly | As required (when tax is due) |
| Format | Online form on vat.gov.bd | Bank receipt or online payment slip |
| Required for filing | Must submit regardless of payment | Only required when net tax is payable |
Both documents must be retained for at least 5 years as per NBR regulations.

Frequently Asked Questions About VAT Return Submission in Bangladesh
Q1: What is the last date to submit a VAT return in Bangladesh?
The deadline to submit a monthly VAT return in Bangladesh is the 15th of the following month. For example, the VAT return for January must be submitted by 15th February. If the 15th falls on a public holiday, the next working day becomes the deadline.
Q2: Can I submit a nil VAT return if I had no sales that month?
Yes. If your business had no taxable transactions in a given month, you are still legally required to submit a nil VAT return (Mushak-9.1) for that period. Failure to do so can result in penalties even if no VAT is owed.
Q3: What happens if I submit an incorrect VAT return?
If you discover an error after submission, you can file a revised return or submit an adjustment through the NBR portal. However, if the error is discovered during an audit, you may be liable for back taxes, interest, and penalties. It is best to engage a professional VAT consultant to ensure accuracy from the outset.
Q4: Do I need a chartered accountant to submit a VAT return in Bangladesh?
While it is technically possible to file a VAT return yourself, engaging a qualified chartered accountant or VAT consultant — like those at SAM & Associates — significantly reduces the risk of errors, ensures you claim all eligible input tax credits, and gives you professional representation in case of an audit. For complex businesses, professional support is strongly recommended.
Conclusion: Stay Compliant, Stay Confident
Submitting your VAT return accurately and on time is one of the most important compliance responsibilities for any business operating in Bangladesh. With the NBR’s growing emphasis on digital transparency and enforcement, errors and late filings carry greater consequences than ever before.
Whether you’re a first-time filer, a growing SME, or a large corporation managing complex VAT obligations, the right professional support makes all the difference.
