This study analyzes the consumption-stimulating effects of tax cuts across age groups, accounting for demographic shifts in South Korea driven by low fertility and population aging. Using the Survey Report on Labor Conditions by Employment Type and provisions of the Income Tax Act, I construct age-specific Average Marginal Tax Rates (AMTRs) for wage earners and identify exogenous individual income tax changes through a narrative approach to derive proxies for tax shocks. The results from Proxy-SVARs indicate that consumption responses to tax shocks are strongest for individuals under 40, followed by those in their 40s, those aged 60 and above, and those in their 50s. These findings suggest that future demographic transitions will progressively weaken the consumption-stimulating effects of tax cut policies.
