Accounting Is the Foundation of Tax & VAT: Classify Your Head of Accounts Properly
"Head of Account" Actually Means Two Different Things
Business owners often use "head of account" loosely, but it refers to two separate — equally important — classification systems:
- Your internal chart-of-accounts ledger head — the category you assign a transaction to in your own books (e.g., "Repairs & Maintenance," "Professional Fees," "Salaries," "Office Rent").
- NBR's official treasury head of account (economic code) — the 7-digit code under the iBAS++ treasury system that tells the government treasury which revenue head a tax or VAT payment belongs to, used when you pay via A-Challan/e-Challan.
Common NBR economic codes you'll encounter when making a payment:
| Tax Type | Economic Code |
|---|---|
| Income tax — companies | 1112101 |
| Income tax — individuals | 1111101 |
| VAT — domestic goods and services | 1141101 |
| VAT — imported goods | 1141104 |
| Supplementary duty — domestic goods/services | 1141102 / 1141103 |
| Customs duty | 1151101 |
| Stamp duty | 1162101 |
What Happens When the Head Is Wrong
Pick the wrong economic code on a payment, and the money still leaves your account — but it gets recorded against the wrong revenue head. The result is not a refund; it's a compliance gap:
- The Deputy Commissioner of Taxes (DCT) can issue a demand notice for tax you already paid, simply because the payment doesn't appear against the correct tax type during audit.
- For VAT, the VAT office tracks payments by BIN and economic code — a mismatch can mean the payment never shows up in your VAT account, jeopardizing your input tax credit claim.
- Correcting it requires a formal written application to the relevant tax circle or VAT commissioner, attaching the original challan and requesting re-allocation — a manual process that commonly takes several weeks to resolve.
Comparison: Allowable vs Partially Allowable vs Disallowed Heads
The same taka spent can be fully deductible, partly deductible, or entirely disallowed — depending purely on which head you classify it under and whether it meets that head's conditions.
| Expense Head | Treatment | Condition / Limit |
|---|---|---|
| Salaries & bonuses | Allowable | Gross monthly salary over BDT 20,000 must be paid via banking channel |
| Rent, rates & taxes | Allowable | TDS must be deducted when paying rent |
| Perquisites / employee benefits | Partially allowable | Excess over BDT 10,00,000 per employee/year disallowed |
| Entertainment expense | Partially allowable | Capped within a formulaic limit tied to company profit |
| Foreign travel expense | Partially allowable | Capped at 1.25% of disclosed turnover |
| Promotional/publicity expense | Partially allowable | Capped at 0.5% of disclosed turnover |
| Royalty / technical fees | Partially allowable | Capped at 10% of net profit (first 3 years), then 8% |
| CSR expenditure | Partially allowable | Usually capped at 20% of total income or BDT 12 crore |
| Capital expenditure (booked as revenue) | Disallowed | Not deductible as expense — depreciation claimed instead |
| Directors' personal expenses | Disallowed | Added back to taxable profit in full |
| Cash payments | Disallowed | Over BDT 5,00,000/year total, or BDT 50,000 in a single transaction |
| Expenses without TDS/VDS deduction | Disallowed | Entire payment disallowed if tax/VAT not deducted & deposited |
The Most Expensive Mix-Up: Capital vs Revenue
A factory spends BDT 8 lakh overhauling a production machine — replacing its motor and extending its useful life by several years. The bookkeeper posts it under "Repairs & Maintenance" because it "feels" like a repair.
Why Correct Classification Legally Saves More Tax & VAT
- VAT input credit depends on it: a purchase tagged under the wrong VAT-rate ledger (vatable vs exempt vs zero-rated) can silently forfeit input tax credit you were entitled to claim.
- TDS/VDS default follows the head: each expense head carries its own withholding rate — misclassifying a payment under the wrong head means deducting the wrong rate, which itself triggers disallowance.
- Banking-channel thresholds are tracked per head: salary, rent, and general payments each have separate cash-vs-bank thresholds — correct heads make it easy to monitor compliance before the threshold is breached.
- Avoids double taxation: correctly separating capital from revenue prevents claiming the same cost twice (as an expense and again as depreciation) — an error that invites penalty, not relief.
- Keeps you audit-ready: a clean, correctly classified chart of accounts lets your accountant defend every figure on the return with the matching source document, rather than reconstructing intent after the fact.
Every Head Needs Its Own Supporting Document
- Vatable purchases: backed by a proper VAT invoice (Mushak 6.3) to support any input tax credit claim.
- TDS-deducted payments: backed by the TDS certificate issued to the payee under Section 145.
- Capital expenditure: backed by an asset register entry with acquisition date, cost, and depreciation schedule.
- CSR and donations: backed by a board resolution and proof the recipient is an NBR-approved or government-recognized institution.
A 5-Step Practical Classification Checklist
If yes, it's capital. If it just kept the asset running as before, it's a revenue repair.
Deduct at the correct rate before payment, not after — a missed deduction disallows the entire expense.
Separate vatable, exempt, and zero-rated purchases in your ledger so input credit is never missed or wrongly claimed.
Track this per head — salary, rent, and general expense thresholds are tracked separately.
A wrong code is far more expensive to fix after the fact than to verify before you pay.
Your Chart of Accounts Is a Tax Document, Not Just a Bookkeeping File
Every head you assign in your books quietly decides your tax and VAT outcome long before the return is prepared. Businesses that treat classification as a one-time setup task — rather than a discipline reviewed every accounting period — are the ones most often surprised by disallowances, demand notices, and lost input credit they never saw coming.
