ABSTRACT This paper evaluates the impact of Sweden’s R&D payroll tax subsidy on the employment of highly skilled workers, focusing on PhDs and STEM professionals. Unlike traditional R&D tax incentives, which reduce taxable income, this subsidy directly lowers payroll taxes for R&D personnel, making it particularly relevant for SMEs and financially constrained firms. Using firm-level panel data from 2011 to 2019 and a difference-in-differences (DiD) approach, we find that the subsidy significantly increases the employment of high-skilled workers. The effects are consistent across firm characteristics, though some variation exists between smaller and larger firms. To ensure robustness, we conduct additional tests using alternative outcome measures, firms near the subsidy cap, and a linear estimation model. A parallel trends sensitivity analysis further supports the validity of our identification strategy. Our findings contribute to the literature on R&D tax incentives and innovation policy by providing new evidence on the labour market effects of payroll tax subsidies for R&D personnel. These insights are particularly relevant for policymakers designing tax-based R&D support schemes.
