Collaboration at Big 4 level

About AT&C

AT&C is an accountancy firm that combines the quality you would expect of a Big 4 firm with the benefits of close regional ties and personal relationships. This allows us to guarantee a high level of commitment and a close and intensive form of cooperation. We speak your language, instinctively know your needs and deliver high quality with short lead times. The majority of our team are AA, RA or tax specialists.

AT&C’s history

AT&C is an offshoot of Ernst & Young, one of the Netherlands’ Big 4 accountancy firms. We set up our own independent operations in Tiel following a management buy-out in 2007.

Our office has experienced considerable growth, confirming our conviction that the combination of quality and commitment produces successful collaborations.

We should point out that this growth is reflected in both quality and quantity. As a result of our flat organisational structure and relatively large number of in-house accountants and specialists, clients can expect to find themselves working with a genuine ‘heavyweight’.
