Credits do not match. PE finds $318 that TA does not allow.

Re-checked against the VT IN-111 PDF:

• Line 23 / Line 25 (VT tax before refundable credits): $65
• Line 26f (refundable credits): $2,204
• Line 27 (net refund): $2,139

Engine outputs:

• PE: siitax = -$2,137.38 → refund $2,137 ✓ matches TaxAct ($2,139 within $2 rounding)
• TAXSIM-35: siitax = -$1,818.91 → refund $1,819 (off by ~$320 vs TaxAct)
• TaxAct (IN-111 Line 27): refund $2,139

So PE matches TaxAct on this record; the $318 gap is between TAXSIM-35 and TaxAct, not PE and TaxAct. PE's refundable credits ($2,202.17) decompose as:

• VT CDCC: $383.26
• VT EITC: $818.91
• VT CTC: $1,000.00
• Total: $2,202.17 ✓

Which lines up with TaxAct's Line 26f = $2,204 (within rounding).

Could the discrepancy be on the TAXSIM-35 side? Possibly TAXSIM is computing one of the VT credits with a different parameter — VT CDCC (Title 32 § 5828(b)) at 72% of federal CDCC, VT CTC ($1,000 per child under 6 for incomes ≤ $125K), or VT EITC (40% of federal EIC).

Closing as PE-TaxAct aligned; TAXSIM appears to be the outlier.
