A sole proprietorship does not really get dissolved so much as it stops. There is no entity to wind up, no shareholders to pay out. One month you are trading and the next you are not — because you retired, took a job, or it simply ran its course.
What does not stop is the paperwork. You are left with years of receipts, a spreadsheet, a bank account you are about to close, and no clear sense of what you are allowed to throw away.
Keep them, and keep them somewhere you will still be able to open. The IRS ties record retention to what it calls the period of limitations — the window in which you can amend a return to claim a credit or refund, or the IRS can assess additional tax — which means the clock runs from the filing, not from the day you stopped trading. The general period is three years, with longer periods in specific situations and separate treatment for employment tax and property records. Before you close the bank account and the mailbox, get the source documents downloaded into a plain, portable format you control. Estimates — confirm with your tax professional.
The records outlive the business
This is the part that catches people. Closing the business feels like an ending, and it is reasonable to assume the obligations end with it. They do not. An audit window does not close because you stopped trading — it closes on its own schedule, measured from when you filed.
Which means the least convenient moment to be missing records is a year or two after the business is gone, when the bank account is closed, the email address is inactive and the paperwork is in a box somewhere. Everything below is aimed at making that moment survivable.
How long to keep what
The IRS does not publish one number, and any page that gives you a single figure is simplifying something that genuinely has branches. It frames retention around the period of limitations, which it defines as "the period of time in which you can amend your tax return to claim a credit or refund, or the IRS can assess additional tax."
Within that framing, the periods the IRS names are:
- 3 years — the general case, where none of the longer situations apply.
- 3 years from filing, or 2 years from when you paid the tax, whichever is later — for a claim for credit or refund filed after the original return.
- 7 years — for a claim involving worthless securities or a bad debt deduction.
- 6 years — where unreported income exceeds 25% of the gross income shown on the return.
- Indefinitely — if no return was filed, or if a fraudulent return was filed.
- Employment tax records: at least 4 years after the date the tax becomes due or is paid, whichever is later. This is a separate rule, and it applies if you ever had employees.
- Property records — keep until the period of limitations expires for the year in which you dispose of the property. These matter for depreciation and for working out gain or loss on disposal, which is exactly what happens when a business closes and its equipment is sold or converted to personal use.
Source: IRS — How long should I keep records? Read 2026-08-15. These are US federal rules; other countries set their own periods and we are not going to invent an equivalent here.
The retention rules in general — for a business that is still running, and for receipts specifically — are covered in more depth on our receipt organizer page. This post is about the closure case, where the practical problem is less "how long" and more "will the records still be readable when someone asks".

The formats problem nobody warns you about
Here is the genuinely under-discussed part, and it needs no tax authority to make the case. Retention rules assume the records still exist in a readable form. Most of the formats a small business actually keeps records in are not built to last several years unattended.
Thermal receipts fade — not theoretically, routinely. Photos live on a phone you will replace. Bank portals keep history for a limited window and none at all once you close the account. And the mailbox where every emailed receipt landed may be a business address that gets shut off shortly after the business does.
| Format | Will you open it in seven years? | Why | What to do |
|---|---|---|---|
| Thermal paper receipt | Poor | The print fades. A few years in a drawer and some are blank. | Photograph it now; the image is the record, not the slip. |
| Photo on your phone | Poor unless moved | You will replace the phone. Photos tied to one device or one account go with it. | Move the images into storage you own and can still open later. |
| Bank or card portal history | Time-limited | Online history is typically available for a limited window — and not at all once the account is closed. | Download the full history as files before closing the account. |
| Email inbox | Depends on the account | A work or business mailbox may be shut down. Receipts in it go with it. | Scan or export what is in there before the account closes. |
| Spreadsheet in storage you own | Good | A plain, portable format, readable by anything, not gated behind a subscription. | Keep the summary and the source documents together in one place. |
The through-line is that every fragile format has the same fix: get the content out of the fragile place and into a plain one, before the account closes rather than after.
Where records should actually live after you close
The durable answer is unglamorous: a plain, portable summary plus the source documents, in storage you control, not inside a subscription. A spreadsheet is a good format for this precisely because it is boring — it opens in anything, it does not need a login to a company that may not exist in five years, and a human can read it without special software.
That last point is worth being blunt about, because it is the one that matters when you are closing something. If your records live inside a tool you are about to stop paying for, find out now what you keep when you leave. Ask it of whatever you use. Some tools export cleanly; some export a format only they can read; some hold your history behind an active subscription.
For what it is worth, that question is the reason ExpenseBot works the way it does: the categorized sheet lives in your own Google Drive, and it stays there whether or not you keep using the product. You keep the sheet, the history and the records. If you are winding down and you used ExpenseBot, there is nothing to migrate — the file is already yours, already in your Drive.
One thing worth doing before you close a business mailbox: run a last scan over it, so the emailed receipts sitting in there become rows in the sheet rather than disappearing with the account. ExpenseBot's Gmail scan labels what it reads and never sends or deletes anything, so a final pass over a mailbox you are about to shut down does not disturb what is in it. The expense tracker template is a reasonable structure if you would rather assemble the summary by hand, and income and expense tracking covers the both-sides view if the final year needs reconciling.
We are not going to pitch you a subscription on the way out. If you are shutting down, the useful thing we can tell you is how to leave with your data intact — from us or from anyone else.
A closing checklist for the records side only
Scoped deliberately to records. The other parts of closing a business are real, and they are covered in the next section by pointing you at the people who should actually answer them.
- Reconcile the final year while you still remember it. The last few months of a winding- down business are usually the messiest and the least documented.
- Download source documents rather than saving links. A link into a vendor portal is not a record — it is a promise that a third party will still be hosting something for you. Save the file.
- Export the bank and card history in full before closing the accounts, as files.
- Do a last pass over the business mailbox before it is shut down, so emailed receipts are captured somewhere else.
- Get the images off the phone and into the same place as everything else.
- Write down where it all lives — one note, in plain language, saying what the records are and where. Tell whoever might need to find them. This is the step everyone skips and it is the cheapest one on the list.
- Keep it for the retention period that applies to your situation, per the IRS guidance above and your tax professional's read of it.
The parts that are not ours
Closing a business involves several things this page has no standing to instruct you on, and it would be a disservice to pretend otherwise. Here is who to ask instead.
- Final return and forms. The IRS publishes guidance on closing a business, including that a sole proprietor files Schedule C (Form 1040 or Form 1040-SR), and that other forms may apply depending on circumstances — Form 4797 where property was sold, Schedule SE for self-employment tax. Start at IRS — Closing a business (read 2026-08-15) and take the specifics to your tax professional.
- EIN cancellation. The IRS lists this among the steps of closing a business and describes it as done by letter. Follow its instructions, not ours.
- Licences, permits and state registrations. These are state and local, they vary, and the IRS itself notes that you should check your state responsibilities when closing a business. Go to the relevant authority.
- Employees and final payroll. If you had any, this is a professional's job — final wages, employment taxes and contractor reporting all have their own requirements.
- An accountant. If you do not have one for the final return, this is a reasonable moment to get one. Accountants use ExpenseBot free, so handing over a clean sheet costs them nothing.
