The Taxpayers' Alliance Town Hall Rich List highlights the number of local authority executives whose total annual remuneration exceeds more than £100,000.
According to their research, in 2016-17 there were 115 employees in Wales receiving remuneration packages worth more than £100,000 a year, up from 107 in 2015-16.
Council tax bills have recently been issued by Welsh Councils for this financial year, and many taxpayers will see significant increases.
Councils have in part justified this by saying that they have made all the savings they can.
However, the Town Hall Rich List shows that Councils across Wales spent huge sums on senior management in 2016-17.
While in February this year every Council in Wales increased Council Tax by an inflation-busting average of 5.07%, above the informal cap set by the Welsh Labour Government.
In February, Cardiff Council raised income tax by 5% and Swansea Council raised income tax by 4.9%.
The Welsh local authority with the most employees receiving remuneration packages in excess of £100,000 in 2016-17 was Cardiff Council with 14.
This was followed by Swansea with 12 employees enjoying remuneration packages in excess of £100,000 in 2016-2017.
Over the last two decades the Labour-controlled Welsh Government in Cardiff Bay has reigned over rising Council taxes in Wales.
Hardworking Welsh families are being let down by successive Welsh Labour administrations that have presided over Council Tax rises of more than 200% since 1997.
Councils across Wales and the Welsh Government need to set an example by reigning in excessive remunerations and be mindful of how Council tax erodes the household finances of hardworking families across Wales.
