Almost all work is tax deductible. This isn't just for software developers and employees still pay taxes. The issue is software development is being classified as research which is one of the few areas where salaries aren't directly deductible but instead need to be deducted in pieces over five years.
Proft = income - expense.
When you pay people to get work done for a business, that paid work is an expense.
You can deduct expenses from your income to calculate your profits.
IIRC the problem is that software development is not being classified as an operating expense, now, but rather a "research" capital expense, and the deductions then have to be amortized over a number of years.
You're confusing corporate vs personal taxes. The salaries businesses pay are meant to be deductible business expenses. The business only pays taxes over the profit after these expenses are deducted from their revenue. The person receiving the salary still owes personal taxes over the income.

What really? How does this work.
