Section 2 — Required inputs and refusal catalogue

Required inputs

Minimum viable — bank statement for the month in CSV, PDF, or pasted text. Must cover the full period. Acceptable from any Bangladeshi bank: Dutch-Bangla Bank, BRAC Bank, Eastern Bank, City Bank, Standard Chartered BD, HSBC BD, Islami Bank, or any other.

Recommended — sales invoices (Mushak-11) for the period, purchase invoices with supplier BIN, the client's BIN in writing (13 digits).

Ideal — complete Mushak-6.1 (purchase register), Mushak-6.2 (sales register), prior period Mushak-9.1, reconciliation of excess credit brought forward.

Refusal policy if minimum is missing — SOFT WARN. If no bank statement is available at all, hard stop. If bank statement only without invoices, proceed but record in the reviewer brief: "This Mushak-9.1 was produced from bank statement alone. The reviewer must verify that input VAT claims are supported by compliant Mushak-11 invoices bearing supplier BIN and that all classifications match supporting documents."

Bangladesh-specific refusal catalogue

R-BD-1 — Turnover tax client attempting to claim input VAT. Trigger: client is turnover tax registered (annual turnover BDT 30 lakh to BDT 3 crore). Message: "Turnover tax payers pay a flat 3%/4% on turnover and cannot recover input VAT. This skill can prepare the turnover tax return but cannot calculate input VAT recovery for a turnover tax client."

R-BD-2 — Export Processing Zone (EPZ) entity. Trigger: client operates in an EPZ or Special Economic Zone. Message: "EPZ/SEZ entities have special VAT rules outside the standard Mushak-9.1 framework. Please escalate to a qualified chartered accountant familiar with EPZ obligations."

R-BD-3 — Multi-establishment with separate BINs. Trigger: client has multiple business units each with a separate BIN. Message: "Each BIN files a separate Mushak-9.1 with inter-establishment transfers on Mushak-6.4. This requires consolidation analysis beyond this skill. Please use a qualified practitioner."

R-BD-4 — Supplementary Duty computation. Trigger: client manufactures or imports goods subject to Supplementary Duty (tobacco, alcohol, vehicles, SIM cards). Message: "Supplementary Duty rates vary widely (7.5%–500%) and SD is calculated before VAT. This requires specialist product-level analysis. Please escalate to a qualified chartered accountant."

R-BD-5 — Withholding VAT agent obligations. Trigger: client is a designated VDS withholding agent (government entity, bank, NGO, listed company). Message: "VDS withholding obligations require tracking of Mushak-6.10 certificates and deposit schedules. Out of scope for standard return preparation. Please use a qualified practitioner."

Section 3 — Supplier pattern library (the lookup table)

This is the deterministic pre-classifier. When a transaction's counterparty matches a pattern in this table, apply the treatment directly. Do not second-guess.

How to read this table. Match by case-insensitive substring on the counterparty name as it appears in the bank statement. If multiple patterns match, use the most specific. If none match, fall through to Tier 1 rules in Section 5.

Section 4 — Worked examples

These are six fully worked classifications drawn from a hypothetical bank statement of a Dhaka-based self-employed IT consultant.

Example 1 — Standard domestic sale at 15%

Input line: 05.04.2026 ; ABC TECHNOLOGIES LTD ; CREDIT ; Invoice BD-2026-041 IT consultancy ; BDT 115,000

Reasoning: Domestic sale of IT consulting services to a BDT-paying local company. Standard 15% applies. The gross amount includes VAT. Net = BDT 100,000, VAT = BDT 15,000. Report in Mushak-9.1 Part 2. Mushak-11 tax invoice must be issued.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Return section	Default?	Excluded?
05.04.2026	ABC TECHNOLOGIES LTD	+115,000	+100,000	15,000	15%	Part 2 (output)	N	—

Example 2 — Local purchase with input tax credit

Input line: 10.04.2026 ; COMPUTER SOURCE BD ; DEBIT ; Office supplies ; BDT -23,000

Reasoning: Purchase from a local VAT-registered supplier. Assuming valid Mushak-11 held with supplier BIN. Net = BDT 20,000, VAT = BDT 3,000 at 15%. Input VAT claimable in Part 6.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Return section	Default?	Excluded?
10.04.2026	COMPUTER SOURCE BD	-23,000	-20,000	3,000	15%	Part 6 (input)	N	—

Example 3 — Export, zero-rated

Input line: 15.04.2026 ; STUDIO KREBS GMBH ; CREDIT ; Invoice BD-EXP-018 Software development ; BDT 350,000

Reasoning: Export of IT services. Zero-rated under VAT & SD Act 2012 Section 24. Report in Mushak-9.1 Part 3 at 0%. Input VAT on related purchases is fully recoverable. Bank realization certificate required within 6 months.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Return section	Default?	Excluded?
15.04.2026	STUDIO KREBS GMBH	+350,000	+350,000	0	0%	Part 3 (export)	N	—

Example 4 — Non-resident digital service (reverse charge)

Input line: 18.04.2026 ; GOOGLE IRELAND LIMITED ; DEBIT ; Google Workspace April ; BDT -2,800

Reasoning: Service from non-resident. No VAT on invoice. Client must self-assess VAT at 15% under reverse charge (Section 18(3)). Self-assessed output = BDT 420. If used for taxable supplies, input credit of BDT 420 also claimable. Net effect zero for fully taxable client.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Return section	Default?	Excluded?
18.04.2026	GOOGLE IRELAND LIMITED	-2,800	-2,800	420	15%	Part 2 (output) + Part 6 (input)	N	—

Example 5 — Blocked input: passenger vehicle

Input line: 22.04.2026 ; TOYOTA BANGLADESH ; DEBIT ; Lease payment Corolla ; BDT -85,000

Reasoning: Passenger vehicle lease. Input VAT blocked under VAT & SD Act 2012 Section 49 — personal consumption / passenger vehicle unless transport business. IT consultant does not qualify. Full block, zero recovery.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Return section	Default?	Excluded?
22.04.2026	TOYOTA BANGLADESH	-85,000	-85,000	0	—	—	Y	"Vehicle: blocked"

Example 6 — Bank charges, excluded

Input line: 30.04.2026 ; DUTCH-BANGLA BANK ; DEBIT ; Monthly maintenance fee ; BDT -500

Reasoning: Bank charges are exempt financial services. No VAT. Exclude from VAT return entirely.

Output:

Date	Counterparty	Gross	Net	VAT	Rate	Return section	Default?	Excluded?
30.04.2026	DUTCH-BANGLA BANK	-500	—	—	—	—	N	"Exempt financial service"

Section 5 — Tier 1 classification rules (compressed)

5.1 Standard rate 15% (VAT & SD Act 2012, Section 15)

Default rate for any taxable supply unless a reduced rate, zero rate, or exemption applies. Sales go to Mushak-9.1 Part 2. Purchases go to Part 6.

5.2 Reduced rates (Third Schedule, various SROs)

5%, 7.5%, or 10% on specified goods/services as gazetted via Statutory Regulatory Orders. Each reduced rate has its own line in Part 2. Check current SRO schedule before classifying.

Purchase must be used for making taxable supplies. Valid Mushak-11 with supplier BIN required. Claim within 3 return periods from invoice date.

5.6 Input tax credit — apportionment

If business makes both taxable and exempt supplies: creditable input = total input x (taxable supplies / total supplies). Annual adjustment required. Flag for reviewer.

Zero VAT recovery regardless of other rules: personal consumption, passenger vehicles (unless transport business), entertainment (unless documented promotion), purchases without valid Mushak-11, purchases from unregistered suppliers, goods lost/stolen/destroyed (unless insured), free samples (unless documented promotional). Check blocked status FIRST before applying any recovery.

5.12 Time of supply (Section 14)

VAT chargeable at the earlier of: invoice date, payment receipt, or delivery. Advance payments trigger VAT at receipt.

Section 7 — Excel working paper template (Bangladesh-specific)

The base specification is in vat-workflow-base Section 3. This section provides the Bangladesh-specific overlay.

Sheet "Transactions"

Columns A-L per the base. Column H ("Return section") accepts: Part 2, Part 3, Part 4, Part 6, Part 7, or blank for excluded transactions. For reverse-charge transactions, enter "Part 2 + Part 6" in column H.

Sheet "Return Summary"

One row per Mushak-9.1 part:

| Part 2  | Output tax on local sales      | =SUMIFS(Transactions!F:F, Transactions!H:H, "Part 2") |
| Part 3  | Export sales (zero-rated)       | =SUMIFS(Transactions!E:E, Transactions!H:H, "Part 3") |
| Part 4  | Exempt supplies                | =SUMIFS(Transactions!E:E, Transactions!H:H, "Part 4") |
| Part 5  | Total output tax               | =Return_Summary!C[Part2_row] |
| Part 6  | Input tax local purchases      | =SUMIFS(Transactions!F:F, Transactions!H:H, "Part 6") |
| Part 7  | Input tax imports              | =SUMIFS(Transactions!F:F, Transactions!H:H, "Part 7") |
| Part 8  | Total input tax credit         | =C[Part6_row]+C[Part7_row] |
| Part 9  | Net tax payable                | =C[Part5_row]-C[Part8_row] |
| Part 12 | Total payable                  | =MAX(C[Part9_row],0) |

Sheet "Return Form"

Final Mushak-9.1-ready figures. If Part 8 > Part 5, excess credit carried forward (no refund claim via this skill).

---

Section 8 — Bank statement reading guide

Follow the universal exclusion rules in vat-workflow-base Step 6, plus these Bangladesh-specific patterns.

CSV format conventions. Dutch-Bangla and BRAC Bank exports typically use comma delimiters with DD/MM/YYYY dates. Common columns: Date, Description, Debit, Credit, Balance.

Bengali/Bangla language variants. Some descriptions may appear in Bangla script. Treat transliterated equivalents the same as English.

Internal transfers and exclusions. Own-account transfers between client's DBBL, BRAC, bKash accounts. Always exclude.

Proprietor draws. Self-employed sole proprietors cannot pay themselves wages. Any transfer to personal account is a drawing. Exclude.

bKash/Nagad transactions. Mobile financial service transactions appear as "BKASH", "NAGAD". Transaction fees are exempt. The underlying payment may be a sale or purchase — classify based on counterparty, not the payment method.

Foreign currency transactions. Convert to BDT at the transaction date rate. Use Bangladesh Bank reference rate.

---

Section 9 — Onboarding fallback (only when inference fails)

9.1 Entity type

Inference: sole trader names match account holder; company names end in "Ltd", "Limited", "Pvt Ltd". Fallback: "Are you a sole proprietor, partnership, or company?"

9.2 Registration type

Inference: if asking for Mushak-9.1, VAT registered. If turnover below BDT 3 crore, may be turnover tax. Fallback: "Are you VAT registered (BIN holder, 15%) or turnover tax (3-4%)?"

9.3 BIN

Inference: 13-digit BIN may appear in payment descriptions. Fallback: "What is your 13-digit BIN?"

9.4 Filing period

Inference: first and last transaction dates. Monthly for VAT registered. Fallback: "Which month does this cover?"

9.5 Industry

Inference: counterparty mix, sales descriptions. Fallback: "What does the business do?"

9.6 Exempt supplies

Inference: presence of medical/educational/financial income. Fallback: "Do you make any VAT-exempt sales?" If yes and significant, apportionment required.

9.7 Exports

Inference: foreign currency incoming, foreign counterparties. Fallback: "Do you export goods or services?"

9.8 Credit brought forward

Not inferable. Always ask: "Do you have excess credit from the prior period?"

Section 10 — Reference material

Sources

1. Value Added Tax and Supplementary Duty Act 2012 — Sections 2, 5, 14, 15, 18, 24, 25, 45-52, 57, 107, 109-130
2. VAT & SD Rules 2016 — Rules 40-47, Mushak form series
3. NBR Statutory Regulatory Orders (SROs) for reduced rates and exemptions
4. NBR Mushak Online Portal — https://vat.gov.bd

Known gaps

1. Supplier pattern library covers major Bangladeshi banks and utilities but not every local vendor. Add patterns as they emerge.
2. Supplementary Duty computation is refused (R-BD-4) — a future version should add SD for common categories.
3. SRO-based reduced rates change frequently. Verify current SRO schedule before each filing period.
4. Multi-establishment (separate BIN) consolidation is refused (R-BD-3).
5. Worked examples are for a hypothetical IT consultant in Dhaka. Sector-specific examples (garments, pharmaceuticals) should be added in v2.1.

Change log

• v2.0 (April 2026): Full rewrite to Malta v2.0 ten-section structure. Supplier pattern library added (Section 3). Worked examples added (Section 4). Tier 1 rules compressed (Section 5). Tier 2 catalogue added (Section 6). Excel template specification added (Section 7). Bank statement reading guide added (Section 8). Onboarding moved to fallback role (Section 9).
• v1.1: Previous monolithic version with full Mushak form mappings and test suite.

Self-check

1. Quick reference at top with return sections and conservative defaults: yes (Section 1).
2. Supplier library as literal lookup tables: yes (Section 3, 10 sub-tables).
3. Worked examples: yes (Section 4, 6 examples).
4. Tier 1 rules compressed: yes (Section 5, 13 rules).
5. Tier 2 catalogue compressed: yes (Section 6, 10 items).
6. Excel template specification: yes (Section 7).
7. Onboarding as fallback: yes (Section 9, 8 items).
8. All 5 Bangladesh-specific refusals present: yes (Section 2).
9. Reference material at bottom: yes (Section 10).
10. Blocked input VAT explicit: yes (Section 5.7 + Example 5).
