Technology startups have access to tax incentives that most other businesses do not - an R&D credit that can offset payroll taxes before the company has any income, a $10 million capital gain exclusion for qualified small business stock, and stock option structures that allow founders and employees to receive equity with minimal current tax cost. But the same startups face an unexpected burden: the OBBBA requirement to capitalize and amortize domestic research and development costs over 5 years, eliminating the immediate deduction that made early-stage R&D spending tax-efficient for decades.
Pre-OBBBA: Research and experimental (R&E) expenditures under §174 were immediately deductible in the year incurred. A startup spending $500,000 on engineering salaries deducted $500,000 in year one.
Post-OBBBA (P.L. 119-21): Domestic R&E expenditures are now capitalized and amortized over 5 years (15 years for foreign R&E). The $500,000 in engineering costs becomes $50,000 deductible in year one (half-year convention applies). The remaining $450,000 is amortized over the following years. This change significantly increases taxable income for R&D-intensive companies in early years.
The R&D credit is separate and unaffected: The §41 R&D credit calculation is based on qualified research expenses and is not changed by §174A capitalization. Both provisions apply simultaneously.
The research and development tax credit under IRC §41 equals 20% of qualified research expenses (QREs) above a base amount, or 14% under the alternative simplified credit (ASC) method. For startups, the ASC method is simpler - it equals 14% of QREs above 50% of average QREs for the prior three years. In the first years with no prior QRE history, the ASC rate is 6% of current year QREs.
What qualifies as QREs: wages paid to employees performing qualified research, contract research expenses (65% of amounts paid), and supply costs consumed in research. Software development costs incurred to develop software for internal use or for sale qualify if the development involves technological uncertainty and experimentation.
Section 1202 excludes 100% of gain on the sale of qualified small business stock (QSBS) held for more than 5 years, up to the greater of $10 million or 10x the taxpayer's adjusted basis. For a founder who invested $100,000 at formation and holds for 5+ years, up to $10 million of gain on a startup exit is completely excluded from federal income tax. The requirements: the corporation must be a domestic C-corporation, aggregate gross assets must not have exceeded $50 million at any time before or immediately after issuance, and the corporation must be an active business in a qualifying industry (technology, software, manufacturing qualify; professional services, finance, hospitality do not).
The 10x basis multiplier matters for later-round investors: a Series A investor who puts in $2 million excludes up to $20 million of gain. The $10 million floor matters for founders with small initial investments. QSBS planning - ensuring the corporation stays under the $50 million asset threshold at issuance, documenting original issuance directly from the corporation, and tracking holding periods - should begin at formation, not at the Series A.
Incentive stock options (ISOs) and nonqualified stock options (NSOs) create different tax events. ISOs: no ordinary income on grant or exercise (though the spread at exercise is an AMT preference item); long-term capital gain on sale if the holding period is met (2 years from grant, 1 year from exercise). NSOs: ordinary income at exercise equal to the spread between fair market value and exercise price; long-term capital gain on post-exercise appreciation after a 1-year holding period.
ISOs are generally better for employees at companies expected to appreciate significantly - the deferral of ordinary income recognition and the capital gain treatment at sale saves substantial tax at exit. The AMT exposure at ISO exercise is the primary risk, particularly for large exercises at high valuations. NSOs are simpler and are the only option for consultants, directors, and advisors (non-employees cannot receive ISOs).
When a founder receives equity subject to vesting, the default tax rule is that income is recognized as each tranche vests - at the fair market value at vesting. For a fast-growing startup, that means ordinary income at the high valuation when shares vest, not at the low value when shares were granted. The §83(b) election, filed within 30 days of receiving the restricted stock, elects to recognize income at grant (usually minimal for founders receiving shares at near-zero value) and converts all future appreciation to capital gain. Missing the 30-day window is permanent - there is no late-filing relief for §83(b) elections.
