These days I'm a hired gun generally on the audit side of the business. Most of the engagements I have are related to Mergers & Acquisitions or companies with accounting systems which are either being migrated to new platforms or have serious issues with their books for a number of reasons.

At one point I did tax accounting, held an EA and did some tax and representation work. I was also in the process of prepping to take the Tax Court Practitioners (TCP) exam. I think in the end, I felt audit suited me better than tax.
