About Canada Legal Services Invoicing
Canadian lawyers (barristers and solicitors) must follow Law Society billing rules in their province. GST/HST applies to legal services at the applicable rate. Legal disbursements are generally taxable unless they qualify as exempt supplies. Legal invoices are subject to strict professional conduct rules in most jurisdictions. Solicitors, barristers, and attorneys must provide detailed time records, clearly itemize disbursements (court fees, expert witness costs, filing fees), and provide billing narratives that allow clients to understand what they are paying for. Trust accounting rules may also apply when client funds are held.
Frequently Asked Questions
What must a solicitor's invoice include in the UK?
In the UK, a solicitor's invoice (called a 'bill of costs') must itemize work done and disbursements, include the VAT registration number if applicable, and be signed. Clients have the right to request an itemized bill and can apply to court for assessment if they dispute it.
How are legal disbursements handled on invoices?
Disbursements (third-party costs paid on your client's behalf) should be listed separately from your professional fees. They may or may not attract VAT/GST depending on their nature. Court filing fees, for example, are typically outside the scope of VAT.
What is a retainer and how does it affect invoicing?
A legal retainer is an advance payment held on account. When work is completed, you draw down from the retainer and issue an invoice showing the amount deducted. If the retainer is exhausted, invoice for additional amounts. Always maintain proper trust account records.
Can attorneys charge interest on unpaid invoices?
Yes, with appropriate disclosure. In the US, attorneys can charge interest if disclosed in the engagement letter. In the UK, the Late Payment of Commercial Debts (Interest) Act 1998 entitles businesses to statutory interest of 8% above base rate on overdue commercial invoices.
How does GST/HST work on Canadian invoices?
Canada levies a 5% federal Goods and Services Tax (GST). In participating provinces, GST is combined with a provincial component into the Harmonized Sales Tax (HST) — for example, 13% in Ontario and 15% in Nova Scotia. In Quebec, GST and QST (9.975%) are charged separately. Businesses with annual revenue over $30,000 CAD must register, collect, and remit GST/HST.
Do I need a Business Number on my Canadian invoices?
If you are registered for GST/HST, you must display your 15-character Business Number (BN) on all invoices — this is your 9-digit BN followed by the program identifier (RT) and a 4-digit reference number (e.g., 123456789 RT0001). Invoices without a valid BN cannot be used by your clients to claim Input Tax Credits (ITCs).
Are there different invoicing rules by Canadian province?
Yes. Provinces that use HST (Ontario, New Brunswick, Nova Scotia, Newfoundland, PEI) require a single combined tax line. Quebec requires separate lines for GST and QST, and QST-registered businesses must also show their QST number. British Columbia, Saskatchewan, and Manitoba charge GST plus their own Provincial Sales Tax (PST), which may have separate registration and invoicing requirements.
