Is This Right For You?

Who We Serve in Riverside

We work exclusively with startups and early-stage companies.
If you fit any of these profiles, you are exactly who this service is built for.

PRE-REVENUE

You have incorporated but are not yet generating revenue

You still need to file Form 1120 with the IRS every year, even with zero activity. And if you have a Delaware C-Corp, you owe the California Franchise Tax Board $800 minimum. We handle both, and make sure you do not miss either.

SEED TO SERIES A

You have raised a round and now have investors watching your books

Investors expect clean financial statements, accurate tax filings, and on-time compliance. A missed filing or late return is a disclosable event that complicates your next round. We make sure your tax house is in order from day one.

DELAWARE C-CORP IN CA

You incorporated in Delaware but operate in California

Most funded Riverside startups do this, and end up with filing obligations in both states. Delaware charges a franchise tax. California charges its own. We handle both returns and make sure you are registered correctly in California as a foreign corporation.

FOREIGN FOUNDER

You or your co-founders are not U.S. citizens or residents

Foreign founders face additional IRS reporting requirements with penalties starting at $10,000 for late or missed filings. We specialize in U.S. tax compliance for internationally-founded startups and make sure every required form is filed accurately and on time.

R&D COMPANY

You have engineers, contractors, or compute costs in your budget

You almost certainly qualify for federal and California R&D tax credits, and claiming them requires filing your income tax return on time. Our income tax service coordinates directly with our R&D Credit Study so you do not leave that money on the table.

SWITCHING CPAS

You have had a legacy local CPA but need a startup specialist

Legacy Local CPAs are not startup-native. They miss R&D credits. They do not know Delaware franchise tax quirks. They charge hourly for every question. We are built for exactly this transition, and we make onboarding fast and painless.

The Full Breakdown

Everything Covered in the $2,450 Annual Fee

No line-item surprises. No add-on fees for standard filings.
This is everything your Riverside startup gets for one flat annual price.

Federal Federal Income Tax Return (Form 1120)

Your annual federal corporate tax return, prepared accurately and filed on time. We handle the full Form 1120 - including all required schedules - and coordinate the filing with your California return so nothing is missed.

1099 Preparation and Filing

If your startup paid contractors $600 or more during the year, you are required to file 1099s with the IRS. We prepare and file all required 1099s - including 1099-NEC and 1099-MISC - as part of the flat annual fee.

Payroll Software Setup

Getting payroll right from the start prevents expensive fixes later. We set up your payroll software - Gusto, Rippling, or your preferred platform, and ensure it is configured correctly for California employment tax compliance from day one.

California State Income Tax Return

California has its own federal income tax requirements, filed separately from your federal return. We handle both the Franchise Tax Board filing and the minimum $800 franchise tax so you stay in good standing with the state.

Delaware Franchise Tax Report

If your startup is incorporated in Delaware, which most funded startups are, you owe the state an annual Franchise Tax Report. We prepare and file it for you. No extra charge. This is one of the most commonly missed filings for California-based Delaware C-Corps.

Bookkeeping Consultation

We get your books in order and ensure you have the tools to stay on top of your financials. This is not full bookkeeping, it is the baseline organization your startup needs to have accurate records for tax filing and investor reporting.

Unlimited tax support, all year round.

Questions about a new hire, a contractor payment, an investor distribution, or a state registration? Email or call us. The hourly clock never starts. It is all included in the flat fee.

CALIFORNIA-SPECIFIC

What Riverside Startups Need to Know About
California Corporate Tax

California is the most aggressive state in the country when it comes to taxing corporations.
Here is what the rules actually look like for a Riverside startup, and what happens when you get them wrong.

The $800 Minimum Franchise Tax

Every corporation doing business in California owes a minimum $800 per year to the Franchise Tax Board, regardless of whether you have any revenue. This applies to California corporations and to Delaware C-Corps registered to do business in California. It is due in your first year of operation.

Delaware vs. California: You Likely Owe Both

If you incorporated in Delaware and operate in California, you have tax obligations in both states. Delaware charges a franchise tax based on your authorized shares or assumed par value. California charges its own franchise tax plus federal income tax on California-sourced income. We handle both.

California Apportionment Rules

If your startup has revenue from multiple states, California uses an apportionment formula to determine how much of your income is subject to California tax. Getting this calculation wrong, in either direction,  is a common and costly mistake for growth-stage startups.

CA Water's Edge Elections

If your startup has foreign subsidiaries or operates internationally, California requires you to make a Water's Edge Election to limit your state tax filing to U.S.-based income. Without it, California can tax your worldwide income. Most founders with international operations have no idea this election exists — until they get the bill. We identify whether it applies to your startup and handle the election correctly.

Do NOT file late if you have foreign founders or shareholders.

Getting payroll right from the start prevents expensive fixes later. We set up your payroll software - Gusto, Rippling, or your preferred platform, and ensure it is configured correctly for California employment tax compliance from day one.

Common Questions

Federal Income Tax Questions From
Riverside Founders

Do I need to file a corporate return if my Riverside startup has no revenue?

Yes. C-Corporations are required to file Form 1120 with the IRS every year regardless of revenue or activity. If you have a Delaware C-Corp operating in California, you also owe a California Franchise Tax Board filing and the $800 minimum franchise tax. Skipping these filings,  even with no revenue, creates penalties and is a disclosable event in future fundraising due diligence.

My startup is incorporated in Delaware but based in Riverside. What do I actually owe?

You owe the Delaware Division of Corporations an annual Franchise Tax Report (due March 1). You also owe California's Franchise Tax Board for the state federal income tax return and the $800 minimum franchise tax. You need to be registered as a foreign corporation with the California Secretary of State. We handle all of this as part of the flat annual fee.

Can I ask questions throughout the year - or only during tax season?

Any time. Our federal income tax service is a fixed annual fee, which means your questions are covered all year: no hourly clock, no per-question billing. We get calls about new hires, contractor payment thresholds, investor distributions, state registrations, and more. It is all included.

We have a foreign co-founder. Does that affect our filing requirements?

Yes, significantly. Foreign founders and foreign shareholders trigger additional IRS reporting requirements; including Form 5472 for foreign-owned U.S. corporations. Filing late or missing these forms results in automatic penalties starting at $10,000 per form. We identify these obligations in the first call and make sure every required form is filed on time.

When do I pay? Is there a contract?

You pay after your returns are filed, not before. There is no binding contract. You can cancel at any time. We do not believe in locking startups into agreements, we keep clients because the service is genuinely useful, not because they are stuck.

Does this service include R&D tax credit work?

The income tax service and the R&D Credit Study are separate services, but they work together closely. If your startup qualifies for R&D credits (which many Riverside tech and cleantech companies do), we coordinate the R&D study with your tax return so the credit is properly claimed on your filing. R&D studies are priced at 0.75% of Qualified Research Expenses.
