Proactive, Year-Round Tax Planning

Tax planning shouldn't begin when it's time to prepare your return. I work with business owners year-round to evaluate opportunities, anticipate tax consequences, and make informed decisions before transactions occur or deadlines pass.

Key Highlights:
  • Pass-through entity (PTE) tax strategies
  • Cost segregation and accelerated depreciation planning
  • Tax-efficient retirement and profit-sharing plan setup
Clean books, real numbers

Accounting & Financial Oversight

Accurate financial information is essential to making sound business and tax decisions. I work with your existing bookkeeper or accounting team to review financial results, address accounting issues, and ensure your records support effective tax planning.

For clients needing additional support, I also offer bookkeeping services as part of a tailored engagement.

Key Highlights:
  • Consistent chart of accounts across sister companies
  • Intercompany loan and transfer reconciliation
  • Accrual vs. cash method evaluations
Seeing the whole board

Multi-Entity Tax Coordination

When money flows between operating companies, real estate LLCs and family trusts, single decisions have ripple effects. I align all your entities so one move doesn't trigger an accidental liability.

Key Highlights:
  • Management fee structures and economic substance
  • Passive activity grouping elections (IRC Section 469)
  • State tax planning and nexus management
From LLCs to S-Corps and holding companies

Entity Structure & Tax Considerations

Whether you're launching a new business, acquiring another company, or reconsidering an existing structure, I help evaluate the accounting and tax implications of your options. This includes entity taxation, ownership arrangements, and, when appropriate, coordination with your legal advisors.

Key Highlights:
  • LLC vs. S-Corp break-even analysis
  • Holding company structure for intellectual property and real estate
  • Tax impact of ownership percentages and buy-sell agreements
A sounding board for big decisions

Ongoing Business & Tax Advice

Available all twelve months when major decisions come up: buying major assets, bringing in equity partners or preparing a business for sale.

Key Highlights:
  • Timing of capital purchases (Section 179 and bonus depreciation)
  • Merger, acquisition and recapitalization advice
  • Succession planning and generational transfers
When the IRS or the state writes to you
