PE finds additional credits totaling $317 hat TA does not.

Same election as #932 — the $317 PE applies is the Wis. Stat. 71.05(6)(b)54m.a "Retirement Income Subtraction (credits restricted)" (new for TY 2025), implemented in wi_income_tax.py.

For this filer (HoH single, age 75, $23,157 pension):

• wi_income_tax_before_refundable_credits = $825.76
• wi_non_refundable_credits = $700 (childcare)
• wi_refundable_credits = $0
• Standard path tax: $825.76
• Exclusion path (Schedule SB Line 16): subtract $23,157 pension from WI income → tax = $508.27, but no credits allowed (per Schedule SB instructions, "Caution: if you claim this subtraction, you may not claim any tax credit on Schedule CR and on lines 13 through 20 and 30 through 35 of the Form 1")

PE picks min(standard, exclusion) → exclusion = $508.27

The $317 difference vs TAXSIM-35 is exactly the optimization savings ($825 standard − $508 exclusion). Per Wis. Stat. 71.05(6)(b)54m.a and the 2025 Schedule SB instructions (page 7), an optimizing filer would claim this and save $317.

Note: the bundle's PDF says "Maine Form 1040ME" — looks like the wrong file was attached. Without a WI Form 1 / Schedule SB PDF I can't verify which path TaxAct chose, but TAXSIM-35 explicitly doesn't auto-apply this new TY 2025 election (same as #932).

Same disposition as #932: leaving open while the TAXSIM-vs-PE convention on auto-optimization is settled.

Agreed. Sorry about Maine tax form.
