How to use S-Corp Basis Tracker and understand its results
- Choose the specific arithmetic or checklist scenario and establish its input amounts, dates, rates and criteria from the applicable records. Keep currencies, periods and jurisdictions consistent; review the tool-specific assumptions before interpreting the result.
- Enter beginningStockBasis, beginningDebtBasis, incomeItems, distributions, lossDeductions, debtRepayments using the field table and calculation rules, then run the tool.
- Read endingStockBasis, endingDebtBasis, nondeductibleLoss, distributionExcess. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| beginningStockBasis | Beginning stock basis (currency) | number; minimum: 0 | Required |
| beginningDebtBasis | Beginning debt basis (currency) | number; minimum: 0 | Required |
| incomeItems | Income and contributions (currency) | number; minimum: 0 | Required |
| distributions | Distributions (currency) | number; minimum: 0 | Required |
| lossDeductions | Loss deductions (currency) | number; minimum: 0 | Required |
| debtRepayments | Debt repayments (currency) | number; minimum: 0 | Required |
Enter nonnegative opening bases, income, distributions, debt repayments and losses. Identify distributions above stock basis, deduct loss first against remaining stock then available debt, and return ending bases and unused losses.
stockBefore=beginStock+income; stockAfter=max(0,stockBefore−distributions); debtAvailable=max(0,beginDebt−repayments) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| endingStockBasis | Ending stock basis (currency) | number; minimum: 0 |
| endingDebtBasis | Ending debt basis (currency) | number; minimum: 0 |
| nondeductibleLoss | Loss exceeding basis (currency) | number; minimum: 0 |
| distributionExcess | Distribution exceeding stock basis (currency) | number; minimum: 0 |

}Limitations and assumptions
The model omits debt-basis restoration, repayment gain, nondeductible adjustments and at-risk/passive limitations. Basis depends on detailed records and statutory ordering beyond this simplified input set.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
