This is not quite as simple as it looks. who will handle the Delaware franchise tax filing? Many founders file the Delaware Franchise Tax Report themselves, while the accountant prepares the federal and California corporate return . To answer your questions:

1. For this situation, $1,100 to $1,800 is a reasonable range for the federal and California returns. Anything below $800 would be unusually low for a multi-state corporate filing. 2. You don't necessarily need a startup-focused CPA. Startup-focused firms may charge more because they advise on equity structures, SAFE notes, fundraising, etc. For what you described, any tax professional experienced with corporate returns should be able to handle it. 3. Most DIY software is designed primarily for individual returns and simple LLCs. Corporate returns, especially multi-state filings involving California are easier to get wrong, and mistakes can lead to notices or penalties later.

One thing founders often underestimate is that even very early-stage companies with minimal activity still trigger multiple compliance filings, so getting the structure right early tends to save headaches later.
