Generally, keep records for 6-7 years. Nigeria (FIRS): 6 years, UK (HMRC): 6 years, US (IRS): 7 years for most records, Canada (CRA): 6 years, Australia (ATO): 5 years. Keep permanently: annual accounts, asset purchase records, and legal documents.

What invoice elements are legally required?

Requirements vary by country but typically include: your business name/address, client details, unique invoice number, date, description of goods/services, amounts, tax breakdown (VAT/GST), and your tax registration number.

How do I prepare for a tax audit?

Keep organized, dated records of all transactions. Maintain supporting documents (receipts, contracts, bank statements). Reconcile accounts regularly. Use accounting software for accurate, searchable records. Respond promptly to authority requests.

Do I need to charge VAT/GST on my invoices?

This depends on your registration status and thresholds. UK: VAT if turnover exceeds £85,000. Australia: GST if turnover exceeds $75,000. Nigeria: VAT registration required for businesses above threshold. US: Sales tax varies by state.
