From January 2020 Zimbabwe vat will be reduced to 14.5%
please provide relevant official government link.
There is a link to a downloadable pdf on this page. If you go to the section on VAT is states 14.5%
This being Africa the website is not up to date, but be sure VAT will be 14.5% from 1 January 2020 since this proposal is now law
I take it the Zimbabwe Revenue Authority is the government tax department and it doesn’t use a url ending in .gov.zw such as http://www.zimtreasury.gov.zw/
See Public Notice 47 of 2019 here: https://www.zimra.co.zw/public-notices
