Software development is research
Most engineering spending is research expenditure under Section 174A, deductible right away again from 2025.
Industry tax guide
Tax planning for companies that build software and plan to grow fast.

Software and technology companies spend most of their money on engineers, sell subscriptions in many states, and raise equity on the way to an exit or an IPO.
The tax rules that matter most are about research costs, credits that can offset payroll tax before the company is profitable, stock that may qualify for the QSBS exclusion, and sales tax on digital products.
Compared with a general business
Most engineering spending is research expenditure under Section 174A, deductible right away again from 2025.
States treat SaaS, downloaded software and digital services differently; many tax them.
Stock options, RSUs and 83(b) elections drive payroll and personal tax for employees and founders.
C corporation stock may qualify for the gain exclusion, which affects entity choice from day one.
The rules in detail
Domestic software development costs are deductible right away for tax years starting in 2025, ending five years of mandatory amortization. Companies with average gross receipts of $31 million or less can also apply the change to 2022 through 2024 by amending or electing.
Building new features, architectures and algorithms often qualifies for the research credit. Startups with under $5 million in gross receipts can apply up to $500,000 a year against payroll taxes.
Founders and investors in a C corporation may exclude gain on qualified small business stock; stock issued after July 4, 2025 qualifies for a partial exclusion after three years and full exclusion after five. Many states tax SaaS, and economic nexus can start from sales alone.

Reconcile recurring revenue and cash runway, then coordinate tax planning for development activity, hiring, and ownership changes.
Subscriptions, deferred revenue, cloud costs, development projects, and equity compensation can outgrow a simple cash-in, cash-out view.
Subscription reports, customer contracts, development cost records, capitalization tables, and payroll data give the review a practical starting point. We identify missing information before recommending changes.
If you are a small business under the gross receipts test, often yes. It can produce refunds for years when development costs were amortized. We compare amending with catching up the remaining costs on the 2025 return.
It can if the company is a C corporation with gross assets under the limit when the stock is issued and runs an active qualifying business. Software companies usually qualify; we confirm the details at each issuance.
In the states that tax it, once you pass their economic nexus threshold. We map your customers by state and register where needed.
