How to Create Your Tax Invoice

Recommended Payment Terms

Tax rules set when a tax invoice must be issued, not when it must be paid. In the UK a VAT invoice is normally due to a VAT-registered customer within 30 days of the time of supply. In Australia you must provide a tax invoice within 28 days of a customer's request. In New Zealand you must provide taxable supply information within 28 days of a registered buyer's request for supplies over NZ$200. Singapore expects a tax invoice within 30 days of the time of supply, and India requires invoices for services within 30 days of the supply under Rule 47. Payment terms are separate: agree them in your contract, show the due date on the invoice and keep the two dates apart, because a late tax invoice can delay your customer's tax claim even if they pay on time.

Tax Information

United Kingdom: a full VAT invoice shows a unique sequential number, the time of supply, the issue date if different, your name, address and VAT number, the customer's name and address, a description, and for each item the quantity, VAT rate and amount excluding VAT, plus the total excluding VAT, any cash discount rate, the total VAT in sterling and unit prices; no 'VAT invoice' heading is required (HMRC VAT Notice 700, section 16). Australia: a tax invoice for sales over A$82.50 including GST must say 'tax invoice' and show your business name, ABN, issue date, description with quantity and price, the GST amount and the extent each sale is taxable, plus the buyer's identity or ABN for sales of A$1,000 or more. New Zealand: tax invoices were replaced by taxable supply information on 1 April 2023; above NZ$200 it needs your GST number and the GST amounts, and above NZ$1,000 the buyer's name and an identifier. Singapore: 'Tax Invoice' in a prominent place, your GST registration number, the 9% rate, amounts before and after GST and the GST, in Singapore dollars if invoiced in another currency; a simplified tax invoice is allowed up to S$1,000 including GST. India: Rule 46 of the CGST Rules lists the particulars, including both GSTINs, HSN or SAC codes, place of supply and the rate and amount of CGST and SGST, or IGST. InvoiceQuickly's own PDF is headed 'INVOICE', copies saved business and client tax IDs to new invoice PDFs, shows one 'Tax (x%)' line per invoice and offers USD, EUR, GBP, CAD, AUD, INR and PKR only: it can serve as a UK VAT invoice with a saved VAT number and one VAT rate, but not as an Australian, Singaporean or Indian tax invoice.

Industry context (2026)

Tax invoice rules are changing faster than invoice layouts. New Zealand's Inland Revenue replaced the tax invoice requirement with taxable supply information on 1 April 2023, so the label no longer matters there. India requires businesses whose aggregate turnover exceeded ₹5 crore in any financial year from 2017-18 to register B2B and export invoices on the Invoice Registration Portal, and an invoice that should have an IRN but does not is not treated as an invoice (CGST Rule 48; Notification 10/2023-Central Tax). Singapore's IRAS is phasing in the GST InvoiceNow Requirement, under which in-scope GST-registered businesses submit invoice data to IRAS through InvoiceNow-Ready Solutions on the Peppol network. The UK government plans to mandate e-invoicing for VAT invoices from April 2029, while VAT Notice 700/63 still lets businesses issue paper or PDF VAT invoices today. Australia's business.gov.au and the ATO still require the words 'tax invoice' and the seller's ABN. A downloadable layout cannot meet a clearance or submission requirement on its own; it can only help you get the content right.

Invoicing Tips

• 1Issue a tax invoice only if you are registered. If you are not, call it an invoice; in Australia using the words 'tax invoice' when unregistered is not allowed.
• 2Put your tax number where the buyer will look for it, next to your business name, and label it ('VAT Reg No.', 'ABN', 'GST Reg No.', 'GSTIN').
• 3Show the rate and net amount on every line when an invoice mixes rates or zero-rated items. A single tax line at the bottom cannot show which items carried which rate.
• 4When you invoice in a foreign currency, add the tax total in local currency (sterling in the UK, Singapore dollars in Singapore) and the exchange rate you used.
• 5Delete the fields that do not apply in your country, such as HSN codes outside India, rather than leaving them blank. An empty mandatory-looking field invites a query.
• 6Keep your own copy and the numbering sequence. Tax authorities expect tax invoices to be kept for years (for example six years for UK VAT records and five in Singapore).
