Comprehensive Accounting & Tax Coordination
One CPA reviewing how every company, holding LLC and personal return interacts. Every service is delivered directly by me, Mark A. Colella, CPA.

Business & Individual Tax Preparation
Careful preparation of Form 1120-S (S-Corporations), Form 1065 (partnerships and LLCs) and Form 1040 (individual returns with complex Schedule C and E allocations). I handle federal and multi-state filings.
- Reconciliation of K-1s across all active and passive entities
- Multi-state nexus and apportionment analysis
- W-2 vs. distribution planning for S-Corps
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.
- Pass-through entity (PTE) tax strategies
- Cost segregation and accelerated depreciation planning
- Tax-efficient retirement and profit-sharing plan setup
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.
- Consistent chart of accounts across sister companies
- Intercompany loan and transfer reconciliation
- Accrual vs. cash method evaluations
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.

- Passive activity grouping elections (IRC Section 469)
- State tax planning and nexus management
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.
- 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
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.
- Timing of capital purchases (Section 179 and bonus depreciation)
- Merger, acquisition and recapitalization advice
- Succession planning and generational transfers
