From 1f0cd1b0f918fc3e51441ae08711e65a9ca8d181 Mon Sep 17 00:00:00 2001 From: Max Ghenis Date: Thu, 8 Oct 2026 11:03:59 -0400 Subject: [PATCH 01/10] Make head_is_dependent_elsewhere consumers independent of the head label The federal standard deduction and 17 state formulas read only whether the tax-unit head is claimed elsewhere, so a joint return where one spouse can be claimed was taxed differently depending on which spouse was labelled head. Each formula now applies its jurisdiction's rule for that case (either spouse, single filers only, per spouse, or only when every filer is claimed), using two new label-independent helpers. Adds swap-pair YAML cases and a Hypothesis property test.
