I have a VAT number, but I am exempted from charging or paying VAT. In order to do so, I need to add a specific sentence in my invoices. Does Upwork allow to customise invoices? Or is this automatically done when Upworks verifies my VAT number with my government?
If you entered a VAT number, Upwork will not charge this tax but will print “VAT Reverse Charged” on the invoice you receive from Upwork and you may be required to self-assess VAT on your VAT return under the reverse-charge mechanism applicable to ESS.
