My existing business researched a new product line. Are the costs startup expenses?
New Product Investigation or New Business Startup?. A specific owner scenario, the facts that change the answer, and the records needed for a tax review.
By AE Tax Advisors Team · Updated October 28, 2026
Determine whether the work expands the existing active business, investigates a separate business or constitutes research governed by other provisions. A new product label alone does not decide current expense treatment.
A specific business-owner situation
An operating service firm researches a software product with a different delivery model. It incurs market studies, prototype development and entity-formation costs. Those activities should not all be placed under one startup or advertising account.
Illustrative example, not a client result.
What to establish before filing
- Describe the existing business and proposed activity.
- Separate market investigation from development and organizational work.
- Review each category under its applicable rule.
Which fact changes the answer?
An ordinary improvement to an existing service differs from building a new business or creating a separate asset. Give the advisor a factual project description before asking for the preferred deduction.
A mistake to avoid
Calling all development spending startup costs can miss rules specifically governing research or software activity.
Records that support the decision
- Project plan.
- Vendor scopes.
- Employee project records.
- Existing operations and ownership information.
The decision to document
Ask for a category-by-category treatment and a documented business-start timeline where relevant. Maintain cost detail so later project changes do not require reconstructing every invoice.
