B&H prepares federal and California tax returns for Sunnyvale small businesses, S-corps, LLCs, and tech professionals with stock compensation and RSU income. Flat-rate pricing, no surprises, direct access to Bill or Hannah.
Sunnyvale tax returns are more complex than the national average — stock compensation, R&D credits, California franchise taxes, and high-income AMT exposure are common. We handle all of it under one flat-rate relationship.
Sunnyvale has a high concentration of tech employees and founders receiving ISOs, NQSOs, and RSUs. We calculate AMT exposure, report equity income correctly, and plan strategies to minimize your California tax hit.
For S-corp owners and LLC members, we prepare both the entity return (1120-S or 1065) and your personal return (1040) — ensuring K-1 flow-through is handled correctly and your QBI deduction is maximized.
We calculate Q1–Q4 estimated payments so you never owe large penalties. For Sunnyvale business owners with variable income, quarterly planning is essential to avoid underpayment surprises.
Questions don't stop on April 16. Bill and Hannah are available year-round for tax questions, mid-year planning, and life events — new business, equity liquidity event, home purchase — that affect your taxes.
Federal and California returns for S-corps (1120-S), partnerships (1065), C-corps (1120), single-member LLCs (Schedule C), and sole proprietors — including CA FTB returns (100S, 565, 568).
Form 1040 for Sunnyvale residents — W-2, self-employment income, rental properties, stock compensation, and California Schedule CA adjustments. K-1 pass-through from your business entity handled together.
ISO exercises, NQSO income, RSU vesting — we calculate your AMT exposure, advise on ISO exercise timing, and ensure equity events are reported correctly on your 1040 and CA return.
For Sunnyvale tech startups with qualified research expenses, we document and claim the IRC Section 41 R&D credit — applying it against income tax or payroll taxes for eligible early-stage companies.
We calculate your safe harbor estimated payment amounts for Q1–Q4 and send reminders before each due date — January 15, April 15, June 15, and September 15.
Need more time? We file Form 4868 (individual) or Form 7004 (business) to extend your filing deadline. Note: extensions extend the filing date, not the payment due date — we estimate and pay the balance due with the extension.

S-corps and partnerships are due March 15; sole proprietors and individuals are due April 15. We recommend providing documents by February 28. Filing early avoids penalties, gets refunds faster, and reduces EIN-based identity theft risk.
