Is sales tax or VAT handled differently when buying through CSP vs direct from Microsoft?

Tax handling generally follows standard commercial rules based on your location and the partner's registration, rather than being fundamentally different because of the CSP model — but exactly how tax is calculated, displayed, and remitted can vary by country and by partner.

Because tax treatment is jurisdiction-specific and can genuinely differ in the details, it's best to ask a specific CSP partner (or your own finance/accounting team) how VAT or sales tax will appear on your particular invoices.
