Invoice Requirements
Most tax authorities require VAT invoices to clearly show: your business name and VAT registration number, the customer's details, a unique invoice number, the tax point (date of supply), itemized amounts excluding VAT, the VAT rate and amount, and the total including VAT.
Pro Tip: VAT Rounding
When calculating VAT on multiple line items, calculate VAT per line item and then sum the totals—don't calculate VAT on the summed net amount. Different rounding can cause small discrepancies that complicate reconciliation.
Frequently Asked Questions
What's the difference between VAT and sales tax?
VAT (Value Added Tax) is collected at each stage of production/distribution, with businesses reclaiming VAT paid on inputs. Sales tax is collected only at final sale. VAT is used in 160+ countries including EU, UK, and Australia (as GST). Sales tax is primarily used in US states. For invoice calculations, the math is similar.
How do I calculate VAT from a gross (VAT-inclusive) price?
To extract VAT from a gross price: Net Amount = Gross ÷ (1 + VAT Rate). For example, with 20% VAT: £120 gross ÷ 1.20 = £100 net, with £20 VAT. Common mistake: Don't multiply by the VAT rate—that calculates VAT on gross, not the VAT contained within it.
What VAT rate should I use for my invoices?
VAT rates vary by country and product type: UK standard 20% (reduced 5%), Germany 19% (reduced 7%), France 20% (reduced 5.5%), Australia GST 10%, Canada varies by province. Some services (financial, healthcare, education) may be exempt or zero-rated. Check your local tax authority for applicable rates.
Do I need to show VAT separately on invoices?
In most jurisdictions, if you're VAT-registered, you must show: your VAT number, VAT rate(s) applied, VAT amount, and net and gross totals. Many countries require separate line items for different VAT rates. This enables your business clients to reclaim VAT on their purchases.
How do I handle VAT on international invoices?
Cross-border VAT rules are complex: B2B services within EU often use reverse charge (0% VAT, customer accounts for it). Exports outside VAT zones are usually zero-rated. Digital services to EU consumers use destination country rates. For significant international trade, consult a tax professional.
