“I’ll remember what this was for” — 18 months later

One of the most common recordkeeping problems business owners run into has nothing to do with intentionally taking an improper deduction.

The expense may have been completely legitimate.

The problem is proving it later.

A charge that was obvious when you made it can become surprisingly difficult to explain 12 or 18 months later—especially if the receipt is missing or the business purpose was never documented.

Good recordkeeping helps support the income and deductions reported on your tax return and makes it much easier to respond if the IRS ever asks for documentation. The IRS specifically expects businesses to maintain records that substantiate items reported on their returns. IRS

Here are three habits that can make your records much easier to defend.

1. Keep digital receipts instead of relying on paper

You do not necessarily need filing cabinets full of paper receipts.

Electronic records are acceptable, provided the system maintains complete and accurate information that can be produced if needed. IRS

A practical system might include:

1. digital copies of receipts and invoices
2. the date and amount of the transaction
3. the vendor
4. enough information to establish the nature of the expense
5. a reliable backup or cloud-storage system

The important part is not whether the receipt is paper or digital.

It is whether you can actually find it and connect it to the transaction later.

A folder somewhere on your phone is better than nothing, but a consistent recordkeeping system is much stronger.

2. Keep business and personal activity separate

Using dedicated business bank and credit-card accounts can make recordkeeping significantly easier.

The IRS specifically notes that maintaining separate business and personal accounts is a good practice because it helps distinguish business expenses from personal expenses. IRS

Ideally, use:

1. a dedicated business checking account
2. a dedicated business credit card
3. consistent bookkeeping procedures
4. a process for documenting expenses that are accidentally paid personally

Personal expenses generally are not deductible simply because they were paid from a business account. Similarly, a legitimate business expense does not necessarily disappear because it was accidentally paid personally—but the transaction should be properly documented and recorded. IRS

Keeping everything separated from the beginning makes that process much cleaner.

3. Document the business purpose while you still remember it

This is where many perfectly legitimate expenses become difficult to substantiate.

Instead of assuming you will remember the details later, record the business purpose close to the time the expense occurs.

For certain travel, transportation, and similar expenses, the IRS requires records showing details such as the amount, date, place, and business purpose. IRS

For example:

Business meals:

Keep the receipt and document the business purpose and relevant business relationship.

Business travel:

Keep documentation showing the dates, destination, expenses, and business reason for the trip.

Vehicle use:

Maintain appropriate records of business mileage or other required information rather than attempting to reconstruct it at year-end.

The closer the documentation is created to the actual transaction, the easier it is to establish what happened.

What records should a business keep?

Depending on the expense, supporting documentation can include:

1. receipts
2. invoices
3. credit-card statements
4. bank statements
5. canceled checks
6. contracts
7. mileage logs
8. travel records
9. accounting records

The IRS notes that sometimes more than one supporting document may be necessary to substantiate all elements of an expense. IRS

A bank or credit-card statement may show that you spent money, for example, but it may not by itself establish why the expense was business-related.

That distinction matters.

How long should you keep business tax records?

There is not one universal retention period for every business record.

In general, the IRS says records supporting income or deductions should be retained for as long as they may be needed under the applicable tax-law statute of limitations. Different records can have different retention requirements. IRS

That is why businesses should have a documented retention policy rather than routinely deleting records after filing a tax return.

The bottom line

Good recordkeeping is not about being afraid of an audit.

It is about being able to support the deductions and positions you are already entitled to take.

A consistent system for receipts, separate accounts, and contemporaneous documentation can save a significant amount of time and frustration if questions ever arise.

The best time to build that system is while the transactions are happening—not 18 months later when someone is trying to reconstruct what they were for.
