AATS LLC ("AATS") was established in 2007 by the Partners of our affiliate company KMH LLP ("KMH"). AATS was formed to assume the accounting outsourcing and individual and small business tax compliance services from KMH. It was also done to ensure that KMH could continue to provide services to Hawaii's larger organizations, while AATS would focus on Hawaii's significant small business sector. The two companies often work together to service both AATS and KMH clients on a variety of tax and accounting technical issues.


AATS is managed by Alan Yee. Alan is the Managing Director of AATS LLC and Partner of KMH LLP's Tax Compliance & Business Advisory Services division. Prior to joining AATS and KMH, Alan was the Office Managing Partner and tax department head of Grant Thornton LLP's Honolulu office. Alan has more than 30 years of experience providing tax and business advisory services to corporations, partnerships, non-profits, closely-held businesses and individuals.
