Wolters Kluwer CCH Axcess

CCH Axcess is the terrifyingly massive, incredibly sophisticated apex predator of the "Top 100 Global Accounting Firms." While Drake serves the solo CPA, CCH Axcess is the absolute mathematical engine used by massive, multi-national accounting firms (like BDO or Grant Thornton) who have 5,000 tax professionals collaborating on the most terrifyingly complex corporate tax returns and multi-tiered partnership structures on earth. Its absolute biggest differentiator is "The Common Core Database Architecture." In legacy systems, a client has a file for their tax return, a file for their billing, and a file for their documents. CCH Axcess mathematically fused the entire accounting firm into a single database. When a partner updates a client's corporate address in the billing module, the system mathematically updates the address on the active 1120 Corporate Tax Return instantly. Because it handles the most complex taxes on earth, its "Multi-Tiered Partnership Engine" is legendary. Real estate conglomerates often have partnerships that own other partnerships that own other partnerships. CCH Axcess mathematically maps this entire structural tree. When a $1M loss is recorded at the bottom entity, the engine mathematically pushes that loss through 5 layers of complex K-1 allocations, calculating the exact tax impact for the ultimate parent corporation flawlessly.
