Licensed Accuracy That Saves You Money

Our Certified Public Accountants look for deductions and credits that can slip right past standard DIY tools. These can be very common topics of equity compensation, stock sales, home office deductions, and startup costs.

While seasonal preparers focus on short-term tax planning, we give you year-round tax planning, all in all. Let us optimize contributions, time investments, and strategically plan purchases so you have the minimum taxes due possible in the first place.

IRS Representation & Protection

Our clients receive full IRS audit support — not just “advice.” As licensed CPAs, we represent you directly in front of the IRS and state tax agencies. No added fees, no uncertainty, just peace of mind.

California & Multistate Expertise

Running a business in California means navigating state tax complexities, franchise fees, and local regulations. Our business tax preparation in Sunnyvale ensures your returns are compliant and optimized for both federal and state laws.
