About Isai

Cortez came to tax practice through experience rather than public headlines. He moved into tax services after training in environments where billing, compliance and the calendar of government deadlines matter. That background shaped a pragmatic approach. He places emphasis on clear explanations and realistic options when clients face audits or potential liabilities.
His work includes routine compliance and more adversarial matters. He prepares amended returns, handles penalty abatement requests and negotiates installment agreements. He also assists business clients with payroll and reporting questions, helping them align internal practices to tax rules. In contested matters he appears before state and federal tax agencies to present documentation and argue positions on behalf of clients.
Colleagues describe him as steady under pressure. He balances detail-oriented review with the ability to summarize complex issues for clients who are not tax professionals. That combination proves useful when resolving audits and negotiating practical solutions. Cortez frequently coordinates with accountants and financial advisors to make sure legal steps fit broader financial plans.
