Nobody starts a business because they enjoy filing. But recordkeeping is the difference between a deduction you can take and a deduction you can only argue for — and in an audit, an expense you cannot document generally does not exist.
The good news is that a system that actually works is much simpler than most people assume. It does not require software, a filing cabinet, or a bookkeeper. It requires knowing what to keep, for how long, and a habit of putting things in one place.
The short version
- Three years is the general federal record retention floor. Several situations extend it.
- Keep employment tax records for at least four years.
- Property and asset records must be kept for as long as you own the asset, plus the normal period afterward.
- Digital copies are acceptable, provided they are complete, legible, and retrievable.
- Mileage and vehicle logs must be contemporaneous — reconstructed logs rarely hold up.
How long to keep things
| Record type | Keep for |
|---|---|
| Tax returns and supporting documents | At least 3 years from filing; many advisers say 7 |
| Employment tax records | At least 4 years after the tax is due or paid |
| Records of property and depreciable assets | Ownership period + 3 years after disposal |
| Records for a return that understated income by more than 25% | 6 years |
| Returns not filed, or fraudulent returns | Indefinitely — no statute of limitations |
| Claims for worthless securities or bad debt deduction | 7 years |
| Corporate records, formation documents, partnership agreements | Permanently |
| Bank and credit card statements | At least 3 years; 7 is safer for business accounts |
The "three-year" rule is the assessment window in normal circumstances. But note the two entries that have no end: a return that was never filed and a fraudulent return leave the year open forever. That is a strong argument for filing even a year you cannot pay — filing starts the clock, and not filing means it never starts.
Rhode Island has its own retention and lookback periods, and they do not always match the federal ones. When they differ, keep records for the longer of the two.
What actually counts as documentation
A bank or credit card statement shows that money moved. It does not show what it bought or why the business needed it. For most expenses you want both the proof of payment and the proof of purpose.
| To support | Keep |
|---|---|
| Gross receipts | Invoices, receipt books, cash register tapes, deposit records, 1099s received |
| Purchases and inventory | Vendor invoices, canceled checks, credit card slips |
| Business expenses | Receipts, invoices, account statements, contracts |
| Assets and equipment | Purchase invoice, proof of payment, and disposal records |
| Travel and meals | Receipt, plus the business purpose and who was present |
| Vehicle use | A mileage log with date, destination, purpose, and miles |
| Home office | Square footage measurements, utility bills, rent or mortgage records |
| Payroll | Time records, pay registers, W-4s, filed returns, W-2s and 1099s |
The categories that get scrutinized
Some deductions attract attention because they are commonly abused. These are the ones where documentation matters most.
Vehicle mileage
The single most disallowed business deduction. You need a log recording the date, destination, business purpose, and miles for each trip. Commuting from home to your regular workplace is not deductible.
The word that matters is contemporaneous — kept as you go. A log written in April covering the previous year is exactly what an examiner is trained to recognize, and it rarely survives. Use a phone app; it takes seconds per trip.
Meals
Deductibility rules for business meals have changed several times in recent years, so confirm the current treatment. In every version, the substantiation requirement is the same: the amount, the date, the place, the business purpose, and the business relationship of the people present. Write the purpose on the receipt at the time. You will not remember in fourteen months.
Home office
Requires regular and exclusive use of a space for business. Exclusive means exclusive — a desk in a room that also serves as a guest bedroom generally does not qualify. Keep the measurements and a photograph of the space as it was actually used.
Digital records are fine
The IRS accepts electronic records provided they are complete, accurate, legible, and can be produced when requested. Photographing receipts is entirely acceptable, which matters because thermal receipt paper fades to blank within a couple of years.
A workable digital system:
- Photograph receipts as you receive them and file them in one place.
- Use a folder per tax year, with subfolders by category.
- Name files so you can find them —

- Download bank and card statements yearly — most institutions purge older ones.
Banks typically keep statements available online for a limited window. If you need seven years of records and your bank keeps eighteen months, the gap is yours to close. Download annually.
Records to keep permanently
Some documents outlive every retention rule:
- Articles of Organization or Incorporation, and any amendments
- Operating agreements, partnership agreements, bylaws
- EIN assignment letter
- Property deeds and closing statements
- Records establishing the basis of assets you still hold
- Retirement plan documents
- Prior-year tax returns themselves — the returns, if not every supporting receipt
Basis records deserve particular emphasis. When you eventually sell a property or a business asset, the gain is calculated against your basis — the original cost plus improvements. If you cannot document what you put into it over twenty years, you may end up paying tax on gain you did not actually have.
A system that takes ten minutes a month
- Separate accounts. A dedicated business bank account and card. Every business dollar flows through them. This alone eliminates most of the difficulty.
- Photograph receipts the day you get them. Write the business purpose on anything that is not obvious.
- Once a month, reconcile the account and file the receipts into that year's folder.
- Once a year, download all statements, close out the folder, and start a new one.
That is the whole system. The monthly step is what makes it work — an hour once a month is trivial, while reconstructing twelve months in April is genuinely miserable and produces worse results.
Where we come in
We handle bookkeeping for small businesses across Rhode Island, and we can set up a system sized to your business rather than one built for a company ten times larger. If you are behind — a year or two of unsorted receipts in a box — that is a normal situation and a fixable one. Bring the box.
