Complex Individual Tax Returns | Executive CPA

Complex Individual Tax Returns

Expert tax preparation for executives and high-net-worth individuals. Stock options, multi-state, K-1s, foreign accounts. Big Four expertise for complex situations.

Quick Answer:

Complex individual tax returns involve stock compensation (ISOs, RSUs, NQSOs), multi-state filing, K-1s from partnerships or S-Corps, rental properties, or foreign accounts. If your return exceeds 20-30 pages or includes AMT calculations, you need specialized preparation. Standard complex returns range $750-$1,500. Multi-state filings start at $1,500. High-net-worth returns with trusts and investments range $2,000-$5,000.

Your Return Isn’t “Individual” in the Simple Sense

Not all individual returns are created equal. If you have stock options from your employer, rental properties generating passive income, K-1s from investment partnerships, or income from multiple states, your return requires more than data entry.

It requires a CPA who understands these complexities and knows where the landmines are.

We specialize in individual returns that require more than TurboTax can handle. Our clients are executives, business owners, real estate investors, and high-income professionals whose returns involve multiple schedules, strategic timing decisions, and careful compliance with complex rules.

Signs You Need a Complex Return Specialist

  • You receive K-1s from partnerships or S-Corps
  • You have stock options, RSUs, or equity compensation
  • You file in multiple states
  • You have rental properties or real estate investments
  • You have foreign accounts or income
  • Your return is consistently over 30 pages

Who Needs Complex Individual Tax Services?

Executives & Professionals with Equity Compensation

Stock-based compensation creates tax complexity that many preparers mishandle:

  • Incentive Stock Options (ISOs): AMT calculation, disqualifying dispositions, holding period tracking
  • Non-Qualified Stock Options (NQSOs): Ordinary income recognition, withholding reconciliation
  • Restricted Stock Units (RSUs): Vesting taxation, sell-to-cover tracking
  • 83(b) Elections: Timing requirements, valuation documentation

Getting these wrong can cost thousands in unnecessary taxes or trigger IRS notices.

High-Net-Worth Individuals

Significant wealth creates reporting complexity:

  • Investment portfolio management (cost basis tracking, wash sale rules)
  • Trust and estate coordination
  • Charitable giving strategies (donor-advised funds, appreciated stock donations)
  • Estate and gift tax considerations

Real Estate Investors

Beyond Schedule E basics:

  • Passive activity loss rules and grouping elections
  • Real Estate Professional Status (REPS) qualification
  • Cost segregation depreciation
  • 1031 exchange reporting

Multi-State Filers

Working or earning income in multiple states requires:

  • Determining filing obligations in each state
  • Avoiding double taxation through credits
  • Understanding state-specific rules (NY, CA, and others have aggressive nexus rules)
  • Allocating income correctly between states

Individuals with Foreign Exposure

Complex Tax Situations We Specialize In

Stock Compensation & Equity

Equity compensation is one of the most commonly mishandled areas:

ISOs (Incentive Stock Options):

  • Exercise timing optimization
  • AMT calculation and credit carryforward
  • Holding period tracking for favorable capital gains treatment
  • Disqualifying disposition identification

NQSOs and RSUs:

  • Proper W-2 reconciliation (common source of errors)
  • Supplemental withholding adequacy
  • Cost basis adjustments on Form 1099-B

We track your grants, exercises, and sales across years. Many clients come to us after discovering their preparer miscalculated basis, resulting in overpaid taxes.

Alternative Minimum Tax (AMT)

AMT affects high earners and ISO exercisers. We:

  • Project AMT liability before year-end
  • Calculate AMT credit carryforwards
  • Optimize exercise timing to minimize AMT impact
  • Track credit utilization across years

Multi-State Returns

If you work remotely, travel for business, have rental properties in other states, or relocated mid-year:

  • We determine where you have filing obligations
  • Allocate income correctly between states
  • Apply credits to prevent double taxation
  • Navigate aggressive states like NY and CA

Schedule K-1 Reporting

K-1s from partnerships, S-Corps, and investment funds require careful handling:

  • Reconciling multiple K-1s
  • Tracking partner basis across years
  • Handling publicly traded partnerships (PTPs)
  • Reporting Section 199A QBI correctly

Rental Real Estate

Beyond basic Schedule E:

  • Passive activity loss limitation tracking
  • Real Estate Professional Status documentation
  • Cost segregation depreciation integration
  • Installment sale reporting

Foreign Accounts and Income

U.S. taxpayers with foreign exposure face serious compliance requirements:

  • FBAR (FinCEN 114) for accounts over $10,000
  • Form 8938 for specified foreign financial assets
  • Foreign tax credit optimization
  • PFIC reporting (mutual funds held through foreign accounts)

Penalties for non-compliance are severe—$10,000+ per violation. We ensure you’re compliant.

How We Handle Complex Returns

Year-Round Relationship:
Complex returns benefit from planning, not just preparation. We track your situation throughout the year (ISO exercises, real estate transactions, state changes) so nothing surprises us at tax time.

Detailed Documentation:
We maintain working papers that track:

  • Stock compensation history and basis
  • Partner/shareholder basis across years
  • AMT credit carryforwards
  • State credit carryovers

This documentation protects you in an audit and ensures continuity if your situation changes.

Coordination:
We work with your other advisors (wealth managers, estate attorneys, business CPAs) to ensure your individual return aligns with your overall financial picture.

Proactive Communication:
When tax law changes affect you, we reach out. When we see planning opportunities, we flag them. You shouldn’t have to ask.

Complex Individual Return FAQs

What makes a return “complex”?

Generally, returns with stock compensation, multiple K-1s, rental properties, multi-state filing, or foreign accounts qualify as complex. If your return is consistently over 20-30 pages or takes more than an hour to review, it’s likely complex.

Can you help if my previous preparer made mistakes on stock compensation?

Yes. We regularly fix basis errors from prior years. If you’ve been overpaying taxes due to incorrect cost basis reporting, we can amend returns and often recover overpayments.

I relocated mid-year. How does that affect my taxes?

You’ll likely need to file in both states. We determine the proper allocation of income and ensure you receive credits to avoid double taxation. Some states (like NY) are aggressive about claiming tax from former residents.

Do I really need to report foreign accounts?

If you have foreign accounts totaling over $10,000 at any point during the year, FBAR filing is mandatory. Penalties for non-compliance start at $10,000 per account per year. We ensure proper compliance.

How do you handle RSU cost basis?

RSU cost basis is frequently reported incorrectly on Form 1099-B. Your broker often shows $0 cost basis because the compensation was reported on your W-2. We reconcile these to ensure you’re not double-taxed.

Can you coordinate with my financial advisor?

Absolutely. We regularly work with wealth managers, estate attorneys, and other advisors. Tax planning works best when everyone’s aligned.
