FinnStatement

For self-employed solopreneurs

Understand your own money.

Nobody warned you about the 15.3% self-employment tax, or how much to set aside each quarter. The Bookkeeping Tracker answers both — and shows the IRS rule behind every number, so you can check it instead of guessing.

Bookkeeping Tracker Dashboard tab showing income, expenses, profit, and estimated tax set-aside totals.
What you owe, what came in, and what needs attention.

The spreadsheet you have now

Your sheet records the past. It does not answer the tax question.

01

Nobody warned you about the 15.3%.

Self-employment tax is separate from income tax, and it comes due four times a year. Guess low and there is a penalty. Guess high and your cash sits idle.

02

When you are not sure, you skip it.

If you cannot tell whether something counts as a business expense, the safe move is to leave it off. That caution is expensive, and it comes from not being able to check the rule.

03

Your categories do not match the form.

A generic sheet does not map to Schedule C, so someone reconciles it later — usually a CPA, at CPA rates.

The shift

Keep the spreadsheet. Add the missing context.

The Bookkeeping Tracker turns your records into a working system: Schedule C context, receipt prompts, and a running set-aside number — including the safe-harbor minimum, the amount that keeps you clear of an underpayment penalty even if this year turns out bigger than last.

How it works

Three steps. No bookkeeping theater.

01

Log income and expenses

Keep the spreadsheet habit you already understand. No bank-feed setup, no new app to learn.

02

Use the IRS-cited categories as of 2026

Pick categories that show the Schedule C context and source behind the claim.

03

Check the Dashboard

See profit, tax reserve, receipt gaps, and the number that needs attention next.

Proof you can check

We do not ask you to trust us.

Every category points back to the current IRS source behind it as of 2026. The file gives you the trail so you and your CPA can verify the claim before it lands on a return.

Source trail examples

FinnStatement is educational, not tax advice. The point is to make the source visible so you can check the rule instead of guessing — and consult a tax professional about your own situation before you file.

Honest limits

This is a spreadsheet, not a CPA, and it is not tax advice. If you have payroll, partners, an S-corp, multi-state filings, or someone already keeping your books, hire a professional — you will get more from an hour of their time than from any template. This is built for the stage before that: doing it yourself, and wanting to understand what you are doing.
