Why the Tax VAT Compliance Calendar Bangladesh Matters

Bangladesh operates under the Income Tax Act 2023 and the VAT and Supplementary Duty Act 2012. Both laws are strict on deadlines. Under Section 143 of the Income Tax Act 2023, failure to deposit withheld tax on time triggers an additional 2% interest per six months, and repeated default can lead to penalties of up to BDT 10 lakh alongside criminal proceedings.

The tax VAT compliance calendar Bangladesh consolidates obligations that span the Deputy Commissioner of Taxes (DCT), VAT Commissionerate, RJSC, and Bangladesh Bank — making it the single most useful reference tool any finance team can maintain.

Monthly Compliance Obligations

Monthly deadlines form the highest-frequency obligations on the tax VAT compliance calendar Bangladesh. These recur every month and carry real consequences for delay.

Tax Deducted at Source (TDS) — Monthly Withholding Tax Return

Deadline: 15th of the following month Authority: Deputy Commissioner of Taxes (DCT) Legal Reference: Section 177, Income Tax Act 2023

Every withholding entity — companies, firms, banks, hospitals, clinics, diagnostic centres, and NGOs — must submit their monthly Withholding Tax Return (WHTR) under Section 177 by the 15th of the following month. This return must be supported by TDS challans and relevant documentation.

Importantly, if the 15th falls on a government holiday, the deadline shifts to the next working day.

VAT Return — Mushak 9.1

Deadline: 15th of the following month Authority: VAT Commissionerate / Local Circle Office Legal Reference: Section 64, Rule 47

All VAT-registered businesses must file their monthly VAT return in Mushak 9.1 form. This can now be submitted online through the VAT Online system. Along with the return, supporting documents and the Mushak 6.6 VDS certificate must be prepared.

VAT Payable at Source (VDS)

Deadline: 7th of the following tax period Authority: VAT Commissionerate Legal Reference: Section 14(6), SRO 240-Law/2021/163-Mushok

VDS (VAT Deducted at Source) collected during the prior period must be deposited within the first 7 days of the next period. This is one of the most commonly missed early-month deadlines on the tax VAT compliance calendar Bangladesh.

Mushak 6.6 — VDS Certificate

Deadline: 8th to 10th of the following month Reference: Section 53, Mushak 6.6

The VDS certificate must be issued to the supplier within this window — in three copies: one to the VAT Circle Office, one to the supplier, and one retained for 5 years.

TDS Deposit (Including Salary TDS)

Deadline: 1st to 14th of the following month Reference: Section 146 (Rule 08) and Section 86 (Rule 13)

Tax deducted from salaries and other payments must reach the government treasury within the first 14 days of the following month. Any delay results in a 50% additional deduction surcharge becoming applicable if proof of return submission (PSR) is also absent.

Quarterly Compliance — Advance Income Tax (AIT)

Deadline: 15th September, 15th December, 15th March, 15th June Reference: Section 154, Tax Challan u/s-154 Authority: Deputy Commissioner of Taxes (DCT)

Advance income tax is payable in four equal instalments throughout the year. Each instalment represents 25% of the estimated annual tax liability. Missing even one quarter compounds pressure in the final quarter.

This is a critical item on the tax VAT compliance calendar Bangladesh for any company with significant taxable income, as interest under Section 155 will apply on any shortfall in advance tax payment.

Annual Compliance Deadlines

Annual filings carry the most severe penalties for non-compliance. These are the must-not-miss entries on every tax VAT compliance calendar Bangladesh.

Corporate Income Tax Return

Deadline:

15th January — for companies with June year-end
15th September — for companies with December year-end

Reference: Section 166

This must be accompanied by audited financial statements. Transfer Pricing (TP) documentation under Section 235/238 is required for entities with international transactions.

Withholding Tax Annual Return — Section 238

Deadline: Same as Corporate Tax Return

Annual summary return reconciling all withholding tax deductions during the year.

International Transaction Statement

Reference: Section 237(E) and Section 239(F)

Entities with international related-party transactions must submit an International Transaction Statement and attach a Chartered Accountant’s report (Section 239).

Individual Income Tax Return

Deadline: 30th November Reference: Section 180

Employees and individuals with taxable income must file their personal income tax return by 30 November. Employers who capture employee tax data under the monthly WHTR must ensure employees meet this deadline.

FDI Reporting — Bangladesh Bank

Deadline: Within 30 days of AGM Reference: BB CN 02/2023

Foreign Direct Investment (FDI) quarterly reports are submitted to Bangladesh Bank within 30 days of the relevant AGM. This obligation covers FDI in four quarters.

RJSC Schedule X Filing

Deadline: Within 30 days of AGM Authority: RJSC

The annual summary of share capital, list of shareholders and directors must be filed with RJSC within 30 days of the AGM.

License and Document Renewals

Deadline: Before 30th June Authority: City Corporation / Others

Trade licences, IRC/ERC, Association memberships, Fire clearance, Environment clearance, and BIDA registrations must all be renewed before 30 June each year. Failure to renew by this date risks operational disruption and can trigger tax scrutiny.

TDS Certificate — Section 145

Deadline: 14th of the following month

Every withholding entity must issue TDS certificates to payees by the 14th of each month, evidencing tax deducted in the prior month.

Key Compliance Risk Areas

From my direct experience handling multi-year NBR audits, these are the most frequently missed items on the tax VAT compliance calendar Bangladesh:

1. VDS deposit by 7th — finance teams often conflate this with the 15th VAT return deadline.

2. Mushak 6.6 issuance — the 3-working-day rule (from VAT return date for registered entities) is widely ignored, leading to supplier disputes and audit exposure.

3. 50% surcharge trap — if the person from whom tax is deducted does not provide Proof of Submission of Return (PSR), the withholding entity must deduct 50% more. Many companies miss this when dealing with individual contractors.

4. AIT instalments — missing a quarterly payment results in interest that compounds into a significant additional liability.

Consequences of Missing the Tax VAT Compliance Calendar Bangladesh Deadlines

Under the Income Tax Act 2023:

Late TDS deposit: 2% interest per 6 months plus potential penalty up to BDT 10 lakh (Section 143)
Failure to deduct: Entire payment may be disallowed as a business expense
No PSR from payee: Automatic 50% surcharge on applicable TDS rate
Late VAT return: Simple interest at 2% per 6 months, plus enforcement proceedings

These are not theoretical risks. I have personally handled NBR audits where multi-year TDS shortfalls led to significant tax demands and prolonged negotiations. A properly maintained tax VAT compliance calendar Bangladesh prevents all of these scenarios before they begin.

Final Note

Tax compliance in Bangladesh demands precision in timing, not just accuracy in calculation. The tax VAT compliance calendar Bangladesh FY 2024–25 laid out here gives finance professionals, CFOs, company secretaries, and tax practitioners the full framework to operate without risk.

Keep this calendar active. Set internal reminders 5 working days ahead of each deadline. Assign ownership for each return type. And always cross-reference with the latest NBR orders, as SROs can update rates and procedures within the financial year.
