Frequently Asked Questions
Only if your company is VAT registered. If you're registered, you must show VAT separately on every invoice you issue, including the VAT amount, the rate, and your VAT registration number. If your annual turnover hasn't reached £90,000 or you're not VAT registered for another reason, you don't charge VAT and shouldn't display it. Showing VAT when unregistered can confuse clients and create compliance issues. HMRC requires VAT-registered businesses to display their registration number and calculate VAT correctly on all invoices.
HMRC requires your invoice to include your company's name and address, invoice number and date, your client's name and address, a description of services or products provided, the amount charged, and your VAT registration number if applicable. You must also include a unique sequential invoice number. For VAT-registered companies, you must separately itemize the VAT amount and rate. Missing any required information can result in HMRC penalties and may affect your ability to claim VAT recovery on the invoice.
UK tax law requires you to keep invoices and supporting records for at least six years from the end of the financial year in which they were issued. This applies to both sent and received invoices. HMRC can request these records during tax audits, and failure to retain them can result in penalties and fines. Digital copies are acceptable as long as they're legible and haven't been altered. Many UK businesses keep records longer than six years as a precaution, though six years is the legal minimum.
Payment terms vary by industry, but most UK businesses offer Net 30 (payment due within 30 days of the invoice date). Some offer Net 14 for smaller invoices or immediate payment for first-time clients. Clearly state "Net 30" or "Due by [date]" on your invoice to avoid confusion. Late payment can significantly affect cash flow, and the UK's Late Payment of Commercial Debts (Interest) Act allows you to charge statutory interest and recovery costs if payment is overdue, protecting your business financially.
HMRC doesn't require a specific format, but your invoice numbers must be unique and sequential without gaps or reused numbers. This is essential for audit trails and tax compliance. Formats like "2025-001" or "INV-12345" are both acceptable. The sequential requirement helps HMRC verify that all invoices are accounted for and prevents gaps that might suggest missing transactions. Document your numbering system for consistency and maintain clear records showing how your numbering system works.
Yes, significantly. Limited companies must include their company registration number and registered office address on invoices. Sole traders invoice under their name or business name and typically don't have a registration number. Both must comply with the same HMRC requirements regarding VAT (if registered) and invoice content. Limited companies have different tax obligations and legal liability, which may affect how they manage outstanding invoices and pursue payment disputes through the courts.
There's no strict legal deadline, but best practice is to invoice within five working days of providing services or delivering products. Some businesses invoice immediately, while others batch invoices weekly. HMRC expects invoices to be issued reasonably promptly and to reflect the actual date services were delivered. Delaying invoices can delay payment and create confusion about which period the invoice covers, potentially leading to disputes and cash flow problems for your company.
You should issue a corrected invoice and clearly mark it as a "corrected invoice" or amend the original in your records. If you've already charged the wrong VAT amount, you may need to issue a credit note and re-invoice. HMRC can penalize repeated invoicing errors, especially VAT calculation mistakes. For minor errors that don't affect tax calculations, a corrected version is usually sufficient. However, systematic errors in VAT or missing required information can trigger audits and financial penalties from HMRC.
