If you’re launching a VC-backed startup, chances are you’ll organize as a C corporation. Investors prefer this structure because it offers flexibility and some tax advantages, but it also comes with rules you should understand early on. Knowing how VC-backed startups get taxed will save you from surprises and costly mistakes down the road.
Federal Tax Treatment of C-Corporations
C corps get taxed twice: once on business profits at the 21% corporate rate, and again when profits are paid out to shareholders as dividends. You have to file a business income tax return each year using IRS Form 1120 even if your startup didn’t make money.
Delaware Franchise Tax
Delaware is a favorite for VC-backed startups because of its equity incentives and clear laws. Every Delaware C corp owes an annual franchise tax, regardless of profit. You can choose between two calculation methods to minimize your tax.
The Authorized Shares Method taxes based on the number of shares authorized. Up to 5,000 shares costs $175. Between 5,001 and 10,000 shares, it’s $250. Every 10,000 shares above that adds $85. For example, 10,095 shares have a franchise tax of $335 ($250 plus $85).
The Assumed Par Value Capital Method calculates tax based on your total gross assets and issued shares. It has a $400 minimum and often benefits startups with many shares but lower assets.
If your franchise tax liability reaches $5,000 or more, you must pay in four estimated installments during the tax year. Missing a payment triggers penalties. Also, file your Annual Franchise Tax Report by March 1 to avoid a $200 fine plus 1.5% monthly interest on any outstanding tax.
Fundraising Tax Considerations
The fundraising tools you choose shape your tax obligations and equity structure over time.
SAFEs and Convertible Notes
Many startups raise money with SAFEs (Simple Agreements for Future Equity) or convertible notes. These aren’t taxed when issued, but they affect your cap table and tax situation later.
When a SAFE converts to equity, there’s no immediate tax, but ownership dilution affects capital gains at exit. Convertible notes, treated as debt, may trigger taxable income at conversion, depending on interest or discounts.
409A Valuations and Option Pricing
Before granting stock options, you need a 409A valuation to set the fair market value of your common stock. Missing or mispricing this can lead to hefty IRS penalties, including a 20% tax under Section 409A.
Always work with a qualified third party for your 409A valuation. It’s expected by investors! It also protects your startup and your team.
How Equity Compensation and Stock Options Are Taxed
Equity compensation is a powerful tool for attracting and retaining talent, but the tax rules catch many founders off guard. Mistakes often lead to unexpected tax bills for both founders and employees.
Founder Stock and the 83(b) Election
Founders receiving stock at formation may owe taxes if it has value. Filing an 83(b) election within 30 days locks in a low tax basis, so future gains get taxed as capital gains instead of ordinary income.
Mistake to avoid: Missing the 83(b) election means stock is taxed at vesting, potentially increasing your tax burden.
Stock Options: ISOs vs. NSOs
Startups mainly offer Incentive Stock Options (ISOs) and Non-Qualified Stock Options (NSOs). ISOs generally qualify for lower long-term capital gains tax but may trigger the Alternative Minimum Tax (AMT) when exercised. NSOs are taxed as ordinary income when exercised.
Timing matters! Understanding the differences between ISOs and NSOs as far as tax treatment is critical.
Restricted Stock Units (RSUs)
RSUs aren’t taxed until they vest, and then their market value counts as ordinary income. Any gain after vesting is taxed as capital gains upon sale. Unlike options, RSUs offer little tax-planning flexibility, so track your vesting schedule closely.
Tax Planning Insight
Successful equity strategies start with early planning. You need to coordinate stock options, RSUs, and 83(b) elections alongside your company’s growth and exit goals.

Payroll Taxes
If your startup has W-2 employees, you’re on the hook for payroll taxes. That includes Social Security, Medicare, federal unemployment (FUTA), and any required state-level taxes for unemployment or disability. These obligations apply whether you’re profitable yet or not.
Mistake to avoid: Skipping estimated payroll tax payments can trigger penalties fast. Don’t wait! Build these costs into your cash flow planning from day one.
State and Local Taxes
Startups owe business taxes in the states where they’re formed and operate. These may include income, franchise, and payroll taxes, depending on local state laws.
Hiring remote workers or doing business in other states can trigger tax obligations, known as nexus. Some local governments add their own taxes on top, so it’s another layer to stay ahead of. Keep close track of where your employees live and where your customers are based.
Mistake to avoid: Misclassifying employees as contractors leads to costly back taxes, penalties, and interest if the Internal Revenue Service catches it. Know the rules and keep thorough records to protect your startup.
Sales Tax
If your startup sells SaaS, digital goods, or physical products, sales tax can get tricky fast. Thanks to economic nexus laws, you may owe taxes in states where you don’t even have an office. This often catches founders off guard.
The fix? Keep close tabs on where your clients are and how much you’re selling in each state. Sales tax software helps, but having a tax pro who understands multistate tax rules is your best defense against unwanted surprises like audits or penalties.
International Tax Considerations
Expanding globally or working with international contractors? That opens the door to international tax rules, and the penalties for getting them wrong can be steep.
Depending on IRS rules, you might need to withhold taxes when paying foreign investors or contractors. Tax treaties between countries ease this burden, but only if you follow the right steps.
You may also need to file forms like 5471 or 1042-S to report foreign ownership or cross-border payments. These filings aren’t optional. Skip them and even an early-stage startup could get hit with hefty fines.
Reduce Startup Taxes From Day One
Knowing the right tax strategies early can save your startup a significant amount of money.
QSBS: A Key Tax Break for Startup Founders and Investors
Qualified Small Business Stock (QSBS) can be a game changer for founders and investors. It lets you exclude up to 100% of your capital gains if your startup meets some key requirements.
For instance, your company’s assets need to be under $50 million when you issue the stock, and you must stick to certain operational rules.
Founders should assess QSBS eligibility early to avoid disqualifying actions. For full details on eligibility and benefits, see our Qualified Small Business Stock Overview.
R&D Tax Credit
If your startup is working on new technology, you might qualify for the federal R&D tax credit. This credit covers software, hardware, or process development that involves real experimentation and technical challenges.
To be eligible, your startup should have under $5 million in gross receipts and be within five years of generating revenue. Even if profits are still months or years away, this credit helps offset up to $500,000 in payroll taxes each year, giving your cash flow some breathing room.
Mistake to avoid: Failing to keep detailed records of your research activities. Without solid documentation, you could miss out on this valuable credit or face penalties. Working with a tax pro helps you claim everything you’re entitled to and be ready if the IRS comes knocking.
Deducting Startup Costs
The IRS lets new businesses write off certain startup expenses under Section 195, but only if those business expenses happen during planning and development. This includes things like legal fees, market research, employee training, and marketing expenses before you officially launch.
Keep in mind, personal expenses or anything not directly tied to your business don’t count. Furthermore, most equipment purchases have to be depreciated over time as the equipment loses value.
Organizational costs include incorporation fees, state filings, and setting up corporate bylaws. They qualify for the same deduction, but they’re tracked separately.
You can deduct up to $5,000 each for startup and organizational costs in your first year. If your startup expenses go over $50,000, that deduction starts to shrink dollar-for-dollar. Any costs beyond that have to be written off over 15 years.
Pro Tips From a VC-Focused CPA Firm
Ensure your startup remains compliant and positioned for long-term success with these professional tips.
- Bring in a tax pro early. The earlier you bring in a tax pro, the more they can help you structure your company in the best way, create tax-saving opportunities, and help you navigate future funding rounds with confidence.
- Keep a tax calendar to stay on top of important deadlines. Mark dates for tax filings, 83(b) elections, 409A valuations, and estimated payments. Missing even one deadline could mean penalties or lost benefits.
- Invest in the right compliance tools. Use software to categorize expenses, track receipts, and manage payroll taxes. Tools built for startups reduce manual work and improve audit readiness.
- Don’t overlook tax deductions. Many early-stage expenses qualify, from software subscriptions to legal fees. A tax professional will help you capture every allowable write-off.
- Review your cap table and equity terms often. Convertible instruments, option grants, and SAFEs all affect your tax exposure. A quarterly review helps you catch issues before they become costly.
- Align tax planning with funding milestones. Major events like raising a new round of funding, hiring abroad, or issuing options should trigger a fresh tax review. Founders often underestimate how much timing affects taxes.
