Why This Tool Exists
Installment sales are not just tax strategies. They are cash flow strategies with tax consequences.
This planner helps you map a schedule: what you receive each year, what is taxed as gain, what is taxed as interest, and what net cash flow looks like after estimated taxes.
Execution note: Run the tool, then write down your assumptions and keep the receipts and logs as you go. The strategy that wins on paper only matters if your process holds up in the real world.

This is a planning schedule. Buyer risk, contract terms, and IRS forms matter. Use this to plan cash and estimated taxes, then validate with your CPA.
How To Read The Schedule
Each year includes principal and interest. Principal contains a gain portion based on your gross profit percentage.
The gain portion is modeled at a capital gains rate. Interest is modeled at an ordinary income rate.
The schedule is an execution tool: it helps you plan cash and estimated taxes rather than guessing.
Common Failure Modes
Modeling the tax but forgetting the buyer risk and collection risk.
No buffer for estimated taxes, then scrambling when cash arrives.
Ignoring how the sale interacts with other income in the same year.
What To Hand Your CPA
Sale price, basis, and the proposed payment schedule.
Your assumed tax rates and whether you expect other major income events.
A plan for how you will handle estimated taxes each year of the note.
Documentation Checklist (Keep It Defensible)
- Create a one-page objective memo before you execute (what outcome you are trying to buy).
- Store your assumptions and calculations in a dated PDF (no year-end reconstructions).
- Keep evidence in the same folder structure every month (receipts, logs, approvals).
- Ask your CPA what would make this easy to sign off on, then build that packet.
Primary Sources To Verify Before You Act
Use primary guidance and your own records before you treat any page like a final answer. These are the source layers that should drive the decision.
- IRS installment sale guidance (Publication 537)
- Offering documents, sponsor fee schedules, and transaction counsel memos
- SEC filings or private placement materials where applicable
- Current IRS forms, instructions, and publications for the relevant tax year
- Your actual account statements, payroll reports, entity records, and advisor memos
