The problem

S-corp basis tracking breaks down
in the real world.

The IRS requires accurate basis tracking for every S-corp shareholder, every year. But real S-corps don't look like the textbook examples.

Shareholders join mid-year
Loss allocations must use weighted average ownership — not year-end percentages. Most tools and spreadsheets get this wrong, creating IRS exposure.
Contributions don't come in cleanly
One shareholder pays via Venmo to another who deposits. The bank statement shows the wrong name. QuickBooks has no concept of contribution routing.
Prior years are undocumented
No one tracked basis properly in year one. Now you need an opening balance that anchors everything forward without having to reconstruct every transaction.
What it does

Everything Form 7203 needs.
Nothing you don't.

⚖
Time-aware ownership
Define ownership percentages with effective dates. The app calculates true day-weighted averages for every year, matching the 1120-S methodology exactly.
Weighted avg allocation
↕
Contribution routing
Mark contributions that flow through one shareholder to another — Venmo, Zelle, bank transfer. Economic source and depositor are tracked separately with full audit trail.
IRS documentation ready
◎
Opening balances
No transaction history for prior years? Set an opening stock basis for any shareholder on any date. The basis engine carries it forward correctly from that point.

FAQ

Common questions.

Where is my data stored?
Entirely on your machine, in your browser's localStorage. Nothing is transmitted to any server. If you clear your browser data, export a JSON backup first — the app has a one-click backup export for exactly this.
Does this replace my CPA?
No. SCorp Ledger is a record-keeping tool, not tax advice. It produces structured data and documentation that your CPA uses to prepare Form 7203 and the 1120-S. Think of it as giving your accountant clean inputs instead of a shoebox.
What if my shareholders changed mid-year?
That's exactly what SCorp Ledger is designed for. You define ownership percentages with effective dates, and the app calculates true day-weighted averages for each year — matching the IRS's pro-rata methodology.
Can I use this for multiple S-corps?
Self-serve licences cover one entity. The Professional tier covers unlimited entities — each gets its own configured HTML file with the company's details pre-loaded.
What accounting and banking software does it work with?
SCorp Ledger imports standard CSV exports from any accounting or banking platform — including Xero, QuickBooks, Bluevine, and most major banks. Configurable mapping rules let you assign each row to a shareholder and transaction type, so it adapts to whatever software you already use.
Is this IRS-compliant output?
The tool produces Form 7203 source data, equity waterfalls matching Schedule L / M-2 structure, and shareholder resolutions following standard S-corp documentation practices. Your CPA reviews and signs off — the tool doesn't file anything.
What about Venmo / Zelle contributions?
SCorp Ledger has a dedicated contribution routing flow — you mark which shareholder is the economic source and which is the depositor. The resolution generator includes a dedicated section documenting this for IRS purposes.
What if I don't have historical transaction data?
Use the Opening Balance feature — enter a shareholder's stock basis as of a specific date and the engine carries it forward correctly from there. You don't need to reconstruct every prior-year transaction.
