Overview: Startup Founders with a US LLC
US VCs overwhelmingly prefer Delaware C-corporations. If you plan to raise institutional funding, start with a Delaware C-corp. For bootstrapped startups, an LLC with the option to convert or elect C-corp status provides flexibility. Y Combinator, Techstars, and most accelerators require Delaware C-corps.
Best Business Structure
For startup founders, we recommend: C-Corporation (Delaware), or LLC with C-Corp election

Tax Considerations for Startup Founders
C-corps pay a flat 21% federal corporate tax on profits. Startup founders should understand Section 83(b) elections for founder stock, QSBS (Qualified Small Business Stock) tax exclusion for up to $10 million in gains, and R&D tax credits. Foreign founders face additional complexity around transfer pricing, CFC rules, and GILTI tax.
Important Note for Startup Founders
Foreign startup founders should be aware of the GILTI (Global Intangible Low-Taxed Income) tax, which may tax your home country's entity on the earnings of your US C-corporation. Additionally, transfer pricing rules require that transactions between your US and foreign entities be conducted at arm's length. Proper structuring from the beginning can save significant tax liability and headaches during fundraising due diligence.
Required Tax Forms
As a non-resident startup founder with a US LLC, you'll typically need these forms:
- Form 1120 (C-corp income tax return)
- Form 5472 (if foreign-owned)
- Form SS-4 (EIN application)
- Form 83(b) election (within 30 days of stock grant)
- State franchise tax returns
- Form W-7 (ITIN for foreign founders)
Key Filing Deadline
Form 5472 + Pro Forma 1120: Due April 15 (extension available to October 15). Penalty for non-filing: $25,000. This applies even if your LLC had zero income.
Common Deductions for Startup Founders
These business expenses are typically deductible for startup founders operating through a US LLC:
- R&D expenses (eligible for R&D tax credit)
- Employee salaries and benefits
- Office rent and co-working spaces
- Software and cloud infrastructure
- Legal fees (incorporation, IP protection, contracts)
- Marketing and customer acquisition costs
- Travel for fundraising and conferences
- Insurance (D&O, general liability, cyber)
Tips for Tax Compliance
- Incorporate in Delaware if you plan to raise VC funding
- File your Section 83(b) election within 30 days of receiving founder stock
- Understand QSBS requirements for potential $10M+ tax-free exit
- Set up proper transfer pricing documentation if you have a foreign parent entity
- Consider R&D tax credits — startups can offset payroll taxes
- Maintain clean cap table records from day one
- Use a qualified attorney for all equity issuances
