We reconcile brokerage Form 1099-B data to correct adjusted cost basis figures and model exercise scenarios to mitigate Alternative Minimum Tax (AMT) exposure.

Do you handle California Pass-Through Entity (PTE / AB 150) Tax elections?

Tax Preparation Engineered for Bay Area Complexity

For Silicon Valley professionals, standard tax preparation isn’t enough. When your income is derived from multiple high-value sources—such as W-2 executive salaries, vested RSUs, K-1s from business partnerships, and passive real estate income—generic software algorithms frequently misreport data, trigger double taxation, and leave thousands of dollars in deductions unclaimed.

At Moontree Tax, led by Brandy Phuong, CPA & EA, we view your individual Form 1040 return as the master blueprint of your financial life. We specialize in coordinating your personal taxes with advanced tech equity stock option adjustments, ensuring that $0 basis brokerage errors are caught and corrected before filing. If you operate a side consultancy, we integrate your Schedule C or S-Corporation K-1s to maximize your Qualified Business Income (QBI) deductions.

Furthermore, we provide proactive advisory for major life transitions. Whether you are navigating marriage and the dual-income tax penalty, planning for retirement tax mitigation, acquiring new rental properties, or relocating into or out of California, we ensure your personal tax execution is flawless and audit-proof.

The High-Net-Worth Household Tax Integration

The Profile: A San Jose couple filing jointly. Spouse A is a tech director who liquidated $150,000 in RSUs. Spouse B runs an independent consulting business generating $200,000 in profit.
The Tax Threat: TurboTax automatically pulls the 1099-B, reporting the $150,000 RSU sale with a $0 cost basis (triggering double taxation). Meanwhile, Spouse B is hit with massive self-employment taxes (15.3%) on their sole proprietorship, creating a catastrophic tax bill.
Moontree CPA Execution:
1. We manually file Form 8949, adjusting the RSU cost basis to Fair Market Value at vest, immediately wiping out ~$55,000 in phantom capital gains taxes.
2. We retroactively execute an LLC to S-Corp conversion for Spouse B’s business, eliminating over $12,000 in FICA taxes.
The Result: A flawlessly integrated Form 1040 that saves the household nearly $70,000 in cash taxes while establishing a clean compliance structure for future years.

Frequently Asked Questions About Individual Tax Prep

What documents do I need to provide for individual tax preparation?

We utilize a highly secure, encrypted portal to manage your documents. Beyond standard W-2s and 1099s, we will request supplemental brokerage statements (essential for fixing RSU/ESPP reporting errors), K-1s from any partnerships or S-Corps, and closing disclosures (HUD-1) if you recently purchased or sold real estate.

How do you handle multi-state returns for remote workers?

If you relocated or worked remotely from another state, California’s Franchise Tax Board (FTB) aggressively audits residency claims. We meticulously prepare Schedule CA (540NR) to accurately allocate your W-2 and equity income based on your exact days of residency, preventing California from taxing non-resident earnings.

Do you provide year-round tax projections or just file in April?

Unlike high-volume tax shops, we focus on proactive strategy. For clients with complex equity vesting schedules or high business income, we provide quarterly tax projections to optimize your estimated tax payments, ensuring you avoid IRS underpayment penalties and cash-flow surprises at tax time.
