Cupertino Individual Tax Returns Done Right

Cupertino residents have among the most complex individual tax returns in California — RSU vesting, ISO/NQSO exercises, K-1 pass-through from closely held businesses, and California's top marginal rate. We handle all of it.

RSU & Stock Option Expertise

Cupertino's high concentration of Apple employees and tech professionals means RSU income and stock options appear on nearly every return. We calculate cost basis, AMT exposure, and ensure accurate Schedule D reporting.

Business Owner Returns

For Cupertino S-corp and LLC owners, we prepare both the entity return and your personal 1040 together — K-1 flow-through, QBI deduction, and owner compensation all handled correctly.

California FTB Filing

California taxes RSU income, capital gains, and stock compensation at up to 13.3%. We calculate CA basis adjustments, schedule CA modifications, and ensure your FTB return minimizes double-taxation.

Quarterly Estimated Tax Planning

We calculate your Q1–Q4 safe harbor estimates so you never face an underpayment penalty. Especially important for Cupertino business owners with variable equity income.

How do you handle RSU income on a Cupertino resident's tax return?

RSU income is reported as ordinary income on your W-2 in the year shares vest. We ensure the correct amount is included in your gross income, calculate the cost basis for any shares sold, report capital gains on Schedule D, and reconcile brokerage 1099-B statements against your W-2 to prevent double-taxation.

What is California's tax treatment of stock options for Cupertino residents?

California taxes ISO exercises as ordinary income (no favorable capital gains treatment), unlike federal treatment. For NQSOs, California taxes the spread at exercise as ordinary income at up to 13.3%. We analyze your equity events, calculate CA tax exposure, and advise on ISO exercise timing to manage your California liability.

Can you prepare a return if I have both W-2 income and a Cupertino side business?

Yes. Many Cupertino residents receive W-2 income from Apple or another tech employer and also operate a consulting LLC or side business. We prepare your full 1040 including Schedule C for self-employment income, SE tax, and the QBI deduction if your side business qualifies — alongside your W-2, RSU, and other income items.
