Even if true, a small fraction of engineering time on a project is actually developing that asset. The rest is maintenance and support. The tax code does allow for this distinction, but only if you track hours associated with each kind of work, which basically no one does. And even if they tried, it's difficult because that line is blurry. Tasks are rarely 100% one or the other. Ever fixed a bug by refactoring to make something better? Which kind of engineering is that? Can you justify that to the IRS accountant auditing you?
