year-end-tax-checklist
Produces a personalized year-end tax action checklist covering income timing, deduction bundling, contribution deadlines, loss harvesting concepts, and charitable giving strategies. All jurisdiction-specific deadlines and rules use placeholder markers for the user to verify. Use when the user asks about year-end tax planning, what to do before the tax year ends, or how to optimize their tax position before December deadlines. Do NOT use for filing tax returns (use tax-filing-prep), tracking deductions throughout the year (use tax-deduction-tracker), or calculating quarterly payments (use quarterly-tax-estimator).
