Transaction Pattern Library

This is the deterministic pre-classifier. When a bank statement transaction matches a pattern below, apply the treatment directly. Do not second-guess. If none match, fall through to Tier 1 rules in Section 5.

How to read this table. Match by case-insensitive substring on the counterparty name or description as it appears in the bank statement. If multiple patterns match, use the most specific. If none match, fall through to Tier 1 rules. Amounts are in ZMW (K). Mobile-money references (MTN MoMo, Airtel Money, Zamtel Kwacha) are common in Zambian statements.

Tier 2 Catalogue (Reviewer Judgement Required)

6.1 Home Office Deduction (income-tax traders)

• Home office deduction rule : - Calculate the proportion of the home used for business (dedicated room as a percentage of total rooms or floor area) - Apply that percentage to: rent, ZESCO electricity, water, internet, maintenance - Must be a dedicated workspace; a dual-use room does NOT qualify Conservative default: 0% deduction until reviewer confirms the arrangement. Flag for reviewer: confirm room count / floor-area basis and that the workspace is genuinely dedicated.

6.2 Motor Vehicle Business Use

• Motor vehicle business use rule : - Only the business-use percentage of fuel, insurance, maintenance, and capital allowances is deductible - Client must maintain a mileage log (business trips vs total) Conservative default: 0% business use until a mileage log is provided. Flag for reviewer: confirm the business percentage is documented and reasonable, and the applicable wear-and-tear rate. unconfirmed

6.3 Phone / Internet Mixed Use

• Phone/internet mixed use rule : - Business-use portion only (MTN/Airtel/Zamtel airtime and data) Conservative default: 0% deduction until the business percentage is confirmed.

6.4 Turnover Tax or Income Tax (no free election)

• Regime rule : - ZRA requires turnover tax at K5,000,000 or less unless an exclusion applies; there is no choice by expense level. Changes happen only at the start of a charge year. Flag for reviewer: confirm the regime registered with ZRA is the correct one.

6.5 Rental Income Banding

• Rental income banding rule : - Rental turnover is taxed on its own scale (0% / 4% / 16%); confirm gross rental turnover and that no expenses are netted off before applying the rate Flag for reviewer: confirm the rental turnover figure and band.

6.6 Bad Debt Write-Off (income-tax traders)

• Bad debt write-off rule : - Deductible only if the income was previously declared, all reasonable recovery steps were taken, and the debt is genuinely irrecoverable Flag for reviewer to confirm all three conditions.

Deadlines and filing

Turnover tax and rental income tax: return and payment by the 14th of the next month. Provisional return 31 March; instalments payable 10 April, 10 July, 10 October, 10 January. Annual return and balance 21 June. Moving between turnover tax and income tax happens only at the start of a charge year. Move at the following year if turnover will pass K5,000,000, and notify ZRA on TaxOnline.

How to file turnover tax. Log in at the ZRA portal (www.zra.org.zm, tax portal) with TPIN, password and captcha, enter the one-time password sent to email and phone, then choose Returns, File a return. Enter tax type Turnover Tax, account name and period. Answer "Do you want to file a nil return?": YES then Submit, or NO, Next. Select the income code and enter the taxable amount, one line per source, Next. Confirm the summary, Submit. A reference number is generated. Pay through TaxOnline, TaxOnApp or *858#.

Annual return steps: Corporate income tax; ITF 56 certificate applies. PAYE refunds use ITF/1A.

Penalties and interest

Late return: individual 1,000 penalty units (K400), company 2,000 (K800) per month or part month; turnover tax 250 units (K100). Late turnover tax payment: 0.5% per month or part month plus Bank of Zambia discount rate plus 2%. Other late payment: 5% plus the same interest. Underpaying by a third on estimate: 25%.

Cross-border points

Non-residents pay on Zambian source income; most is by final withholding. Remittances above USD 2,000 need tax clearance.

Two worked examples that recompute

Simple. Employee: see K15,000 in the payroll skill. Annual trader profit K200,000:

name: Trader K200,000
inputs:
  profit: 200000
steps:
  - tax: 4800 + 7560 + (profit - 110400) * 0.37
expected:
  tax: 45512.00

Decision: stay on turnover tax or move up. Same trader, K1,200,000 turnover: ZRA's monthly example gives (K100,000 less K2,500) at 5% for 12 months, K58,500. Income tax would be K45,512, but below K5,000,000 turnover tax is required, so the comparison shows the cost of the regime, not a free choice. If the trade is consultancy, income tax applies.

name: Turnover tax against income tax
inputs:
  monthly: 100000
steps:
  - tot: (monthly - 2500) * 0.05 * 12
  - it: 45512
  - diff: tot - it
expected:
  tot: 58500.00
  diff: 12988.00

Example 5: Non-deductible entertainment (income-tax trader)

Input line: 22/04/2025 ; ABSA CARD ; CHRISMA RESTAURANT ; CLIENT DINNER ; -850.00 ; ZMW

Reasoning: Client entertainment is private/entertainment in nature and not wholly and exclusively for the production of income. Not deductible. No apportionment.

Classification: NOT deductible. Exclude from expenses.

Example 6: Internal transfer (exclude)

Input line: 15/05/2025 ; ZANACO ; OWN ACCOUNT - SAVINGS ; ; -5,000.00 ; ZMW

Reasoning: Transfer between own accounts. Neither income nor expense. Exclude entirely.

Classification: EXCLUDE.

Ask the client first

Required Inputs and Refusal Catalogue

Required Inputs

Minimum viable (employee/PAYE): gross monthly earnings (basic + allowances), and confirmation the person is an employee. Optionally: confirmation of NAPSA/NHIMA applicability.

Minimum viable (self-employed): bank statement for the charge year in CSV, PDF, or pasted text, plus the nature of the business and approximate annual turnover (to decide turnover tax vs income tax).

Recommended: payslips, NAPSA/NHIMA contribution records, sales invoices, purchase invoices/receipts, prior-year ZRA assessment, VAT registration status.

Ideal: complete income and expenditure account, asset register, provisional-tax payment confirmations, employment contract / minimum-wage order applicable to the sector.

Refusal if minimum is missing: SOFT WARN. No earnings figure (employee) or no bank statement (self-employed) = hard stop. Bank statement without invoices = proceed with reviewer warning: "This computation was produced from bank statement alone. The reviewer must verify that all deductions claimed are supported and that the wholly-and-exclusively test is met."

Refusal Catalogue

• R-ZM-1 : Employment status unknown. "PAYE (employee) and turnover/income tax (self-employed) are entirely different regimes. This skill cannot compute tax without knowing the person's status. Please confirm before proceeding."
• R-ZM-2 : Turnover near or above K5,000,000. "Turnover tax applies only to annual turnover up to ZMW 5,000,000 (Income Tax Act s. 64A(2), as amended by Act 17 of 2025). Above this the business files under the standard income-tax regime, and VAT registration may be required. Escalate to a ZICA-qualified accountant."
• R-ZM-3 : Companies, partnerships, group structures. "This skill covers individuals: employees and sole traders only. Companies and partnerships file separate returns under different rules. Escalate to a ZICA-qualified accountant."
• R-ZM-4 : Mining, farming, or special-sector income. "Mining and certain sector incomes are excluded from turnover tax and have bespoke regimes. Out of scope. Escalate to a ZICA-qualified accountant."
• R-ZM-5 : Non-resident / withholding-tax matters. "Most non-resident income is taxed via withholding tax, not the PAYE/income-tax bands. Out of scope. Escalate to a ZICA-qualified accountant."
• R-ZM-6 : Arrears / ZRA enforcement. "Client has outstanding tax arrears or is subject to ZRA enforcement. Late-payment penalties (5% plus BoZ discount rate + 2% interest) compound. Do not advise. Escalate immediately."
• R-ZM-7 : VAT return requested. "This skill covers income tax / PAYE / turnover tax only. For Zambia VAT, use the zambia-vat skill (if available) or escalate."

Conservative Defaults

Conservative Defaults

Ambiguity	Default
Unknown whether earner is employee or self-employed	STOP: do not compute without status
Unknown gross vs net of allowances	Treat the figure as gross monthly earnings
Unknown business-use % (vehicle, phone, home)	0% deduction
Unknown expense category (self-employed)	Not deductible
Unknown whether NAPSA ceiling applies	Apply the NAPSA ceiling (see payroll skill, unverified) ceiling
Unknown turnover-tax vs income-tax regime	Turnover tax if turnover ≤ K5,000,000 (see R-ZM-2)
Unknown VAT registration	Not VAT-registered (use gross amounts)
Charge year not stated	Charge year 2026

Onboarding Fallback

If the client provides a bank statement but cannot answer onboarding questions immediately:

1. Classify all transactions using the pattern library (Section 3)
2. Mark all Tier 2 items as "PENDING: reviewer must confirm"
3. Apply conservative defaults (Section 1)
4. Generate the working paper (Section 7) with clear flags
5. Present the following questions to the client:

ONBOARDING QUESTIONS: ZAMBIA INCOME TAX
1. Are you an employee (paid a salary) or self-employed (run your own business)?
2. If self-employed: what is your approximate annual turnover? (decides turnover tax vs income tax)
3. Does your income include interest, dividends, royalties, consultancy, or mining? (excluded from turnover tax)
4. Are you VAT-registered, or above K800,000 annual turnover?
5. Do you let property? If so, what is the gross annual rent?
6. Home office: dedicated room or shared space? If dedicated, what % of floor area?
7. Vehicle: used for business? If yes, what % business use, and do you keep a mileage log?
8. Phone/internet: what % is business use?
9. Are NAPSA and NHIMA deducted from your pay (employee) or do you pay them yourself?
10. Have you paid any provisional tax this charge year?

PROHIBITIONS

• NEVER compute tax without confirming employee (PAYE) vs self-employed status
• NEVER apply turnover tax to interest, dividends, royalties, consultancy, or standard mining income
• NEVER allow expense deductions for a turnover-tax taxpayer (5% is on turnover)
• NEVER state a NAPSA ceiling as confirmed: it is unverified (see payroll skill)
• NEVER treat NAPSA or NHIMA as a trading expense of the individual
• NEVER allow entertainment, personal, or fine/penalty expenses as deductions
• NEVER allow income tax / PAYE itself as a deduction
• NEVER assume the 2025 NAPSA ceiling, NHIMA split, or minimum wage carries into 2026 without confirmation
• NEVER treat a unconfirmed figure as confirmed : flag it for the reviewer
• NEVER present tax calculations as definitive: always label as estimated and pending professional review
