Why Choose a CPA Over TurboTax, H&R Block, or TaxAct?
This is for those of you earning $75K or more and residing in Seattle, or if you have more than one income source; such DIY tax software could be costing you money. This is why techies, business owners, and professionals trust the CPAs at OptimizeTax over automated tools.

Expert Accuracy That Saves Money
Licensed CPAs don’t just input data; we interpret it. Many Seattle business owners discovered that DIY software missed major deductions. Real example: a client’s home office and depreciation deductions saved over $3,000 that TurboTax didn’t catch.
Year-Round Strategic Tax Planning
While software stops at filing, we go further. We plan your entire financial year from stock sales to major purchases to ensure tax savings throughout. You’ll receive quarterly guidance and year-end strategies designed to minimize your liability and maximize returns.
IRS Audit Protection & Representation
TurboTax provides what is called an "audit support" service that wraps up with an email. Meanwhile, our CPA professionals do auditing services before the IRS on a full basis with every return. Should you ever face an audit, we will stand by you, and all details will be handled in a professional manner.
Washington State Business Tax Expertise
Knowing statewide requirements unique to Seattle businesses, including the B&O tax system, will help one business owner manage. Understanding every classification and exemption makes sure your filings are compliant and, wherever possible, perform in a way that saves you money.
Proven ROI for High Earners
Our Seattle clients earning $100K+ typically save 3–5x our service fee in tax reductions. One tech professional saved $7,800 through timing optimization of their restricted stock units (RSUs) — savings that software never spotted.
Big Tech Stock Compensation Specialists
The employees of Amazon, Microsoft, and Google depend upon us with their complex equity compensation matters. Whether it be about RSUs or ESPP plans, our CPAs are committed to helping you come up with tax-smart strategies to reduce your tax liability and assist you in the efficient planning of future vesting cycles.
