How International Invoice Taxes Work
VAT vs Sales Tax
VAT (Value Added Tax) is levied incrementally at each stage of production and distribution, allowing registered businesses to reclaim input tax. Sales tax is a single-stage consumption tax levied only on the final end-user sale.
Cross-Border Reverse Charge
For B2B cross-border services within the EU or GCC, tax liability shifts from the seller to the buyer under the Reverse Charge mechanism, preventing double taxation across borders.
Withholding Tax (WHT)
In countries like Nigeria, corporate clients deduct 5% to 10% Withholding Tax directly from invoice payments and remit it to the tax authority as an advance income tax credit on your behalf.
Tax Calculator FAQs
What is the difference between tax-inclusive and tax-exclusive pricing?
Tax-exclusive pricing means tax is added on top of the net price (e.g. $1,000 + 20% VAT = $1,200 total). Tax-inclusive pricing means the gross price already includes the tax, so tax must be backed out (e.g. $1,200 gross with 20% VAT contains $200 VAT and $1,000 net). B2B invoices typically use tax-exclusive pricing.
How does the B2B EU Reverse Charge mechanism work?
When a VAT-registered business sells services to a VAT-registered business in another EU member state, the supplier charges 0% VAT. The buyer accounts for both input and output VAT on their local VAT return. The invoice must state "Reverse charge: Customer to account for VAT" along with the buyer's valid VAT number.
