We bought source code and hired developers to modify it. Are all the costs treated the same?
Buying Source Code or Paying for Development?. 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
Acquiring existing code and paying for later development are not automatically one tax category. Separate the purchased rights from modification work and review applicable software, research and capitalization rules.
A specific business-owner situation
A company buys a codebase and hires engineers to add functionality. The vendor's invoice calls everything software services. Rights acquired, research location and the engineers' actual activities need separate records.
Illustrative example, not a client result.
What to establish before filing
- Identify the acquired license or ownership rights.
- Separate purchase price from development and implementation work.
- Review each category under current tax rules.
Which fact changes the answer?
Domestic and foreign development can raise different questions. Tell the advisor where work occurred and what was delivered rather than assuming a vendor's billing address establishes the location of the research.
A mistake to avoid
Treating the entire combined spend as a subscription can ignore both acquired property and development rules.
Records that support the decision
- Code purchase agreement.
- Developer scopes.
- Project time records.
- Acceptance and deployment evidence.
The decision to document
Request a project-cost classification and recovery schedule. Keep enough detail to trace later improvements and avoid folding every future change into the original acquisition basis without review.
