Say a client pays you $130 in cash for a deep clean. The money itself is real enough, but a record of it doesn't exist at this point, and no record is ever going to exist unless you sit down and write one.
Why cash needs its own paper trail
Most payment methods produce their own records as part of how they work, without effort from either party. Cash is the exception to all of it. The bills go from one hand to the other hand, and the systems that would normally be remembering the payment were never part of it to begin with. Which leaves the remembering to the receipt, and the receipt remembers in both directions.
What goes on a cash payment receipt
The IRS definition of a supporting document is short. According to it, the document needs to show four things: the amount paid, the date of the payment, the party who received it, and a description of what was purchased. [1] Think of that as the floor. A receipt you'll actually be glad to have later carries somewhat more than the floor, so here is the whole list, set out roughly in the order it gets written:
- Date: the day the cash was received, not the day the work was scheduled, or the day you got around to your paperwork.
- Your business name and a way to reach you: whoever holds the customer copy has to be able to tell from it who got paid.
- Received from: the full name of the person who paid.
- What the money paid for: a receipt that says "cleaning" tells nobody much of anything, while one that says "move-out deep clean, 2BR apartment at 414 Crestline" has answered most questions before anyone gets around to asking them.
- The amount: in numbers, and for larger payments, it doesn't hurt to spell it out in words the way a check does, since $1,400 and $140 are one sloppy zero apart.
- The word Cash: entered on the payment method line.
- A receipt number: numbered in sequence, either out of a pre-numbered book or from a count you keep on your own.
- Paid in full, or the balance left over: if the $200 being received is a deposit against a $750 job, the receipt needs to come out and say that, since a receipt reading only "$200 received" leaves the customer free to remember $200 as the entire price.
A signature line becomes worth the space once real money is involved.
How to write one by hand in under a minute
A carbonless receipt book from an office supply store is all the equipment this takes. The routine goes like this:
- Start with the date, before you write anything else.
- Enter the payer's full name on the received-from line.
- Describe the goods or the work in one specific phrase.
- Put down the amount, and if the payment is a big one, spell the amount out in words as well.
- On the payment method line, write the word CASH.
- Mark the payment as paid in full, or record the remaining balance if one exists.
- Add a signature or initials, give the top copy to the customer, and keep the carbon copy in the book.
The three readers a cash receipt has to convince
A receipt that holds up has passed inspection by three separate readers, and each of the three reads it for a different purpose.
The customer
If the customer needs their copy months later, it will be for one of a few reasons: a return, a warranty claim, a reimbursement form at work, or a disagreement over what the payment covered.
Your bookkeeping
Your copies are how cash income gets into the books accurately, instead of approximately. Register tapes and receipt records both appear on the IRS list of documents showing where a business's gross receipts came from, and showing that is exactly what your duplicate copies are there to do. [2] One additional habit makes the copies more useful. Whenever cash goes to the bank, write down the receipt numbers that particular deposit is made of.
The IRS
That subject is large enough that it gets a section of its own below.
What the IRS expects when the payment is cash
Start with the income side, since it's the one that gets businesses in actual trouble. Each cash payment your business takes in is part of your gross receipts. Cash produces no 1099 and appears on no statement, and neither of those things reduces what's owed by a dollar. Should anyone ask where the income number on your return came from, the receipt copies in your files are the answer.
There's also the question of how long all of this paper needs to be kept around. The IRS guidance is to keep records supporting a return for at least three years from the date the return was filed. [3] Underreport income by more than 25 percent, and the window stretches out to six years, and for a fraudulent return, or a year where no return got filed at all, the window simply never closes. [4] Given that cash is precisely the income category where underreporting questions come up, keeping cash receipts on the longer end is cheap insurance.
One rule that needs correction here is the $75 rule, since the common version of it is wrong. Under IRS Publication 463, certain expenses under $75, travel and transportation costs mostly, don't require a receipt as documentary evidence on the payer's side. [5] The rule applies to the person spending the money, comes with exceptions, and has nothing to do with a business on the receiving end of a cash payment. A $9 sale and a $900 sale go into the records under the same requirement.
And then the big one. A business that receives more than $10,000 in cash, in one transaction or in related transactions, has to file Form 8300 within 15 days, and then notify the payer in writing by January 31 of the following year. [6] Related transactions get added together under the rule, which means a $12,000 job collected as two payments of $6,000 still requires the filing.
The cash situations people skip, and what to add
Outside of a register, writing the receipt is a decision, and the usual decision is to skip it:
| Situation | Who needs the copy most | The extra detail to write |
|---|---|---|
| Rent paid in cash | The tenant | The rental period the payment covers, not just the date |
| Personal loan repayment | Whoever's paying it back | Running balance still owed after this payment |
| Deposit before a job | Both sides equally | The total job price and the balance remaining |
| Cash refund to a customer | You | The original receipt number being refunded against |
| Marketplace or yard sale, run as a business | The buyer | "Sold as-is" if that's the deal |
| Paying a helper in cash | You, this time | Their name and what the work was, since now you're the one needing proof |
5 cash receipt mistakes that come back around
1. Leaving the payer's name off
A receipt with an empty received-from line establishes that a payment was made to you by somebody, and somebody is not the same thing as the specific customer now disputing the bill. In a payment dispute, the absent name is the opening that the other side gets to use.
2. Skipping the tendered-and-change line
The fix takes three numbers: what was handed over, what was charged, and what came back.
3. Treating a partial payment like a full one
Issue a deposit receipt without the remaining balance on it, and the document is available to be presented later as proof that the full job was paid. Probably not by this customer, but eventually by somebody. Adding the line "deposit $200, balance of $550 due on completion" removes the possibility entirely.
4. Writing receipts for strangers but not for regulars
The books make no allowance for the relationship.
5. Assuming the text thread counts
Texts make a decent backup and a poor substitute for a receipt that states the full transaction in one place.
Frequently asked questions
Is a handwritten cash receipt legally valid?
Yes. Nothing about a receipt requires printing, software, or a special form. A handwritten receipt from a $5 carbon book is a valid record as long as the actual information is on it, the date, the parties, the amount, what it was for, and cash as the method. About the only requirement that handwriting adds to the list is that somebody else has to be able to read it.
How do you prove you paid cash without a receipt?
The honest answer is with difficulty, by gathering up whatever indirect evidence happens to exist. A withdrawal from your bank shortly before the payment, messages arranging the transaction, the goods or completed work itself, a witness. None of those alone equals a receipt, and the time to fix the problem is during the payment, by asking for one.
Does a cash receipt need to be signed?
There is no general legal requirement for a signature on an ordinary receipt.
Do I have to report cash income if there's no 1099?
Yes. The 1099 is a reporting mechanism, not the source of the tax obligation, so a year in which no forms arrive changes nothing about what is owed.
What counts as cash for the $10,000 reporting rule?
In certain transactions, cashier's checks, money orders, and similar instruments fall under the Form 8300 definition of cash, which routinely surprises filers who assumed the rule stopped at paper bills. [6] Before deciding that a large payment falls outside the rule, read the form's instructions, especially if the payment is arriving in anything that resembles cash.
The Bottom Line
A cash receipt is a small document doing a job that nothing else does. Other payment methods document themselves as a side effect of how the money moves. Cash documents nothing, so the minute or so it takes to write the receipt is the entire recordkeeping system for that transaction, on both sides of it. What makes one hold up isn't formality. It's completeness and timing, all the details of the actual exchange, written down while the exchange is still happening.
