Resolution Support

Services

What We Offer Our services are organized across five core areas, designed to meet your clients wherever they are in their financial journey — from active resolution through long-term planning.



Resolution Support The case isn't over until it's truly resolved. We stay in the fight alongside your clients — covering additional liabilities as they surface, stepping in when the IRS escalates to enforced collection, monitoring compliance to catch problems early, and getting stalled cases back on track. Your clients crossed the finish line with you. We help make sure they stay there.

Business Advisory Business-owning clients carry a different kind of tax burden — and they need more than just resolution. We help them get structured correctly, stay compliant, and protect what they've built. From entity formation and S-Corp elections to bookkeeping, P&L reconstruction, Revenue Officer representation, and Trust Fund Recovery Penalty defense, we handle the complexity so they can focus on running their business.

Personal Tax Advisory For individual clients, compliance is just the starting point. We work with them on estimated tax planning, deduction analysis, penalty abatement, amended returns, and practical cash-flow budgeting — keeping them on the right side of the IRS and making sure they're not leaving money on the table year after year.

Long-Term Planning Not every client is ready for long-term planning on day one — and that's okay. When they get there, we're ready. We help clients optimize their business income, plan around major purchases, maximize retirement contributions, and build a tax strategy that works for their future, not just their current situation.

Specialty & Coordinated Services Some client needs go beyond taxes alone. Through our professional network, we coordinate trust planning, retirement programs, charitable giving strategies, and multi-entity structures — bringing in the right specialists and managing the tax side of every engagement so nothing falls through the cracks.
