Common issues include:
- Differences between customs declarations, import records, purchase ledgers, and VAT reporting.
- Input-tax claims without complete supplier invoices, import evidence, or a demonstrated connection to business activity.
- Applying export zero-rating without retaining the evidence required for the specific transaction.
- Inconsistent treatment of scrap, production losses, damaged stock, free samples, staff use, and inventory write-offs.
- Standard costing and overhead absorption that are not reconciled to actual costs, creating unreliable cost of goods sold and taxable profit.
- Unrecorded work in progress, production yield variances, rework, and obsolete or slow-moving inventory.
- Capital equipment and repairs classified inconsistently, or tax depreciation adjustments unsupported by asset records.
- Related-party purchases of components, technical services, licences, or management services without appropriate commercial and pricing documentation.
- Confusing customs duty relief, designated-zone status, and VAT treatment as if they were the same legal test.
Each issue should be evaluated using production evidence, contracts, invoices, stock records, and the rules applicable to the transaction.
Maintain bill-of-materials controls, standard-versus-actual cost analysis, production yield and scrap reports, WIP valuation, batch traceability, stock counts, overhead allocation, and obsolescence reviews. Reconcile material consumption and finished-goods dispatch to inventory and cost of goods sold.
Review import VAT, local input tax, export evidence, domestic sales, scrap transactions, samples, stock losses, and relevant designated-zone movements. Reconcile customs and warehouse data to the purchase ledger and VAT return, and retain documents supporting each treatment.
Support cost of goods sold, production overheads, asset depreciation, capital expenditure, inventory write-downs, and related-party component or service charges. Ensure accounting-to-tax adjustments can be traced to the relevant asset, batch, invoice, or cost pool.
Standardise product and customer master data, units of measure, tax codes, dispatch references, and credit-note links. Integrate ERP with warehouse and billing systems for in-scope B2B/B2G invoices and test partial deliveries, returns, export orders, and quality claims.
