Export Tax Summary with Year-over-Year Comparison When tax preparation tools block automated PDF downloads (via popups or new tabs), capture the structured summary data from the web interface instead. Export line-item data to YAML format with both current and prior-year columns for programmatic comparison. This approach is filing-product-agnostic and survives workflow changes—if next year uses a different tax service, the prior-year YAML remains instantly comparable without manual re-entry. ---
