AMT Preference Items Addback Checklist
Bounded AMT preference/addback evidence record, not a complete return calculation, universal preference list or tax liability determination. Independently witnessed columns in order: tax year and applicable AMT regime established, preference/addback items independently classified, basis/deferral differences documented, applicable exemptions and exclusions reviewed. Missing and unknown remain distinct; this is not legal compliance, coverage, authenticity or safety certification.
Description
An AMT review needs an established regime, classified preference items, documented differences, and reviewed exclusions.
An AMT review needs an established regime, classified preference items, documented differences, and reviewed exclusions.1
This checklist records witnessed, missing, and unknown evidence separately.
When to use AMT Preference Items Addback Checklist
Use this tool when you need to reproduce the stated calculation from measured records or independently selected model inputs. Establish jurisdiction, tax year, applicable authority, and eligible amounts or evidence before entering values.
How to use AMT Preference Items Addback Checklist and understand its results
- Establish jurisdiction, tax year, applicable authority, and eligible amounts or evidence before entering values.
- Enter observedCriterionFlags, criterionKnownFlags, following the field table and rules below, then run the tool.
- Read result. Use the output meanings below to interpret units, signs, flags, and any nested result fields.
- Correct reported input issues and run again. For a successful result, check the stated evidence coverage and assumptions before using it in your review.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedCriterionFlags | Observed criterion flags | list of number | Required |
| criterionKnownFlags | Criterion known flags | list of number | Required |
Enter exactly four binary observed and known flags in order: applicable year/regime, classified preference/addback items, documented basis/deferral differences, reviewed exemptions/exclusions. Known one plus observed one is witnessed; known one plus observed zero is missing; known zero is unknown regardless of observed placeholder. Return the corresponding fixed labels.
status_i=known_i?(observed_i?witnessed:missing):unknown Symbols follow the input and output meanings and the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Calculated observation or qualified reference | object |
| result.witnessedCriteria | Witnessed Criteria | list |
| result.knownMissingCriteria | Known Missing Criteria | list |

}Limitations and assumptions
Eligibility, rates, dates, definitions, and exceptions are independently supplied facts. The arithmetic is not a complete return calculation or a determination of tax liability.
Missing required fields, unknown fields, wrong types, and violated calculation rules are input issues. Numeric values must be finite; nonfinite results are rejected. Evidence arrays must be dense, with no missing cells. Numeric observation lists allow at most 10,000 entries, subject to any smaller bounds stated above. Extremely large composite outputs are rejected.
