My S corp keeps adding unpaid interest to my loan. Is that enough?
Unpaid interest, principal advances and tax basis require separate analysis.
By AE Tax Advisors Team · Updated October 28, 2026
Unpaid interest, principal advances and tax basis require separate analysis. A ledger entry does not establish payment or settle related-party timing. Review the company's method and the shareholder's reporting together.
A business-owner scenario
A founder's note accrues interest each December, but no cash has moved for three years. The corporation deducts the accrual and the owner reports no interest income. A review should explain the timing rule being used and identify any mismatch before the next return repeats it.
Illustrative scenario, not a client result.
Work through the transaction
- Separate original principal from accrued interest.
- Compare both parties' accounting methods and filed reporting.
- Evaluate actual payments and the note's enforceable terms.
The mistake that changes the result
Adding interest to a balance does not automatically produce the same tax result as paying it.
Records that resolve the question
- Note and rate changes.
- Accrual ledger.
- Company returns.
- Owner interest-income schedules.
The decision to document
Request a year-by-year reconciliation and a documented payment policy. If prior reporting was inconsistent, determine the correction procedure before erasing or netting the accrued balance in the current books.
Which fact changes the answer?
A true contractual modification may differ from an internal entry made only to clear an unpaid expense account. Keep evidence of what the parties agreed and when, and have both preparers address the same obligation.
