Monthly VAT Return Submission Guideline

Value Added Tax or VAT is an important part of the tax system in Bangladesh. Every VAT-registered business must submit VAT returns to the National Board of Revenue (NBR) for each ‘tax period’. Usually, the tax period means one month specified in the Gregorian Calendar as per the VAT law. However, there are a few exceptions.

For instance, relating to construction entities, procurement providers, and clearing & forwarding agents that are not withholding entities, the ‘tax period’ is a 6-month period. Proper VAT filing helps businesses stay compliant, avoid penalties, and maintain clear financial records.

Many businesses struggle with VAT forms, online submission, deadlines, and document preparation. A simple understanding of the process can reduce errors and make compliance easier.

This guide explains the monthly VAT return submission process in Bangladesh in clear and simple language, using general terms and without considering exceptions.

What Is a Monthly VAT Return?

A monthly VAT return is a report submitted to the National Board of Revenue (NBR) by VAT-registered entities in Bangladesh. It shows the entity’s monthly VAT-related activities, including sales, purchases, collected VAT, paid VAT, and the final payable amount. Regular VAT submission helps VAT-registered entities maintain proper tax compliance and avoid filing problems.

A monthly VAT return usually contains:

• Total sales during the month (output tax): It shows the total value of taxable sales made by the business during the reporting period.
• Total purchases during the month (input tax): It records the total amount spent on business purchases and taxable procurement activities.
• VAT deducted by customers (decreasing adjustments): This amount represents the VAT charged to customers on sales transactions, and the customers withheld it.
• VAT paid on business purchases (increasing adjustments): It shows the VAT paid by the business while purchasing goods or services from suppliers, and the business withheld it from the payments to its suppliers.
• Final payable VAT amount: The payable VAT is calculated after setting off input tax against output tax, as well as the decreasing and increasing adjustments for the month.

The main form used for monthly VAT return submission in Bangladesh is Mushak 9.1. Businesses must complete the form carefully with correct financial data and submit it within the official deadline. Even if there is no business activity during a month, a nil VAT return must still be filed to maintain proper compliance status with the NBR.

Monthly VAT Return Deadline in Bangladesh

Businesses registered under VAT in Bangladesh must submit their monthly VAT returns within 15 days after the end of each tax period. If the 15th day is a government holiday, the return is to be submitted on the next working day.

However, any government, semi-government or autonomous organization, bank, insurance and individual or institution filing a zero return may submit the VAT return within a maximum of 20 days of the end of the tax period.

The National Board of Revenue (NBR) follows a fixed filing schedule, and businesses are expected to complete both return submission and VAT payment within the official deadline.

The deadline changes based on the reporting month. For example, the VAT return for January must be submitted by February 15, while the February return must be filed by March 15. Businesses usually prepare their sales records, purchase information, and VAT calculations before the filing date to avoid last-minute mistakes.

Late VAT return submission can create financial and compliance problems for businesses. Delayed filing may result in fines, interest charges, and additional scrutiny from tax authorities. Repeated delays can also create difficulties during VAT audits and future tax assessments.

Timely VAT filing helps businesses maintain proper compliance records and organized financial reporting. Regular submission also reduces the risk of penalties, missing documents, and calculation errors. Many companies now use accounting software and online VAT systems to manage deadlines more efficiently.

Who Must Submit Monthly VAT Returns?

Businesses registered under the VAT and Supplementary Duty Act, 2012 must submit monthly VAT returns in Bangladesh. The requirement applies to companies involved in taxable business activities, sales, imports, manufacturing, and services. Regular VAT return submission helps businesses maintain compliance with National Board of Revenue (NBR) regulations. Businesses that usually need to submit monthly VAT returns:

• Manufacturers
• Importers
• Exporters
• Service providers
• Traders
• E-commerce businesses
• Corporate companies

Small businesses operating under turnover tax may follow different filing requirements depending on their registration category and annual turnover level. Businesses should verify their filing obligations carefully to avoid compliance problems and penalties.

Step-by-Step Monthly VAT Return Submission Process

A clear VAT return submission process helps businesses reduce filing mistakes, maintain proper records, and submit returns on time. Organized preparation also makes VAT calculation, payment, and document management easier during monthly compliance activities.

Step 1: Collect Financial Data

Businesses first gather all financial records related to sales, purchases, imports, exports, and VAT deductions for the reporting month. Proper data collection helps create accurate VAT calculations and reduces the chance of missing information during return preparation.

Finance teams usually review invoices, purchase records, sales registers, and payment documents before starting the filing process. Organized records save time and make the return preparation process smoother and more accurate.

Step 2: Calculate VAT Liability

The next step involves calculating output tax collected from sales and input tax paid on business purchases (inputs). After setting off input tax with output tax and making proper increasing and decreasing adjustments, the business determines the final payable VAT amount for the reporting period. The VAT liability may further be reduced if any negative net VAT amount (refundable) is carried forward from any earlier period and adjusted.

Accurate VAT calculation is necessary for proper compliance. Incorrect figures can create filing errors, additional tax liabilities, or problems during VAT audits and inspections by the VATauthority.

Step 3: Prepare Mushak 9.1

Businesses prepare the Mushak 9.1 form using collected financial information and VAT calculation details. The form contains sales figures, purchase data, VAT amounts, adjustment entries, and other required reporting information.

Careful review is important before submission. Businesses should verify the BIN number, sales amount, purchase value, VAT calculations, and adjustment entries to reduce the risk of filing mistakes.

Step 4: Submit Through the Online VAT System

Most businesses in Bangladesh now submit VAT returns through the NBR online VAT portal. The digital system helps businesses complete filing activities more efficiently without depending on manual paperwork.

The online system helps businesses submit VAT returns, manage BIN information, track filing history, and check submission status. Online filing also reduces document handling and improves record management.

Step 5: Pay VAT Liability

Businesses must pay any payable VAT amount within the official deadline through approved banking channels or online payment systems. Timely and accurate payment to the appropriate VAT deposit code and VAT jurisdiction helps businesses avoid penalties, interest charges, and compliance complications.

Payment details should match the submitted VAT return information properly. Incorrect payment amounts or delayed payments may create problems during future tax verification and audits.

Step 6: Store Submission Records

After submission, businesses should keep copies of filed VAT returns, payment receipts, Mushak forms, and all supporting documents. Proper record storage helps maintain organized compliance documentation throughout the year.

These records may be required during VAT audits, inspections, or future tax assessments. Businesses with organized records usually handle compliance reviews more smoothly and face fewer documentation issues.

Documents Needed for VAT Return Submission

Businesses should gather all necessary VAT documents before preparing and submitting monthly VAT returns. Proper documentation helps maintain accurate financial records, supports VAT calculations, and reduces the risk of filing errors during submission or tax audits.

Documents commonly required for VAT return submission:

• Sales Records: Sales invoices and sales registers help calculate output VAT collected from customers during the reporting period.
• Purchase Records: Purchase invoices and VAT challans are used to calculate input VAT claims on business expenses and procurement activities.
• Information on VAT Deduction from Expenses: Any VAT deducted at source from the expenses must be properly recorded with supporting documents and deduction details.
• Information on VAT Deducted at Source from Revenue: Businesses must make decreasing adjustments for the VAT deducted at source from revenue by the customers in the tax period in which the payment (fee) is received against the supply or within the next 06 tax periods thereof through certificates of VAT deducted at source in Form Mushak 6.6, issued by the customers.
• Treasury Challan: Treasury challans or payment receipts work as proof of VAT payment during return submission and verification.
• Previous VAT Returns: Earlier VAT returns help verify carried-forward balances, adjustment entries, and previous reporting information.

Organized records make the VAT return process faster, smoother, and more accurate. Businesses that maintain updated documents regularly usually face fewer compliance issues and can respond more easily during VAT inspections or audits.

Tips for Smooth VAT Compliance

Proper VAT compliance becomes much easier when businesses follow a structured process throughout the year. Regular monitoring, organized documentation, and timely filing help reduce errors, avoid penalties, and maintain smooth communication with the National Board of Revenue (NBR).

4. Train Finance Staff
