Taking cash without creating a mess

General business guidance, not tax or legal advice. Reporting thresholds, forms and deadlines change, and sales tax rules are set state by state. Confirm anything specific with irs.gov, your state revenue department, or a CPA who works with contractors.

The homeowner meets you at the door with a folded stack of twenties for a $640 drain job. No card fee, no waiting three days for the deposit to clear, no invoice to chase. You are back in the truck in two minutes.

Three weeks later she calls: the repair is leaking again and she wants to know what warranty she has. Neither of you has a piece of paper with a date, an amount, or a description of what you installed.

Cash is fine to take. The mess comes from treating "paid on the spot" as if it also meant "nothing to write down."

Write the receipt before the money leaves the doorstep

A cash payment does not replace the invoice — it just means the invoice is already paid when you hand it over. Give the customer a numbered document, keep a copy, and do it at the curb rather than that evening from memory.

A carbonless duplicate receipt book does this on paper: customer takes the top sheet, you keep the copy. Emailing a paid invoice from your phone before you pull out of the driveway does it better, because the customer's inbox becomes a second copy you did not have to file.

Two habits go with it. Count the bills in front of the customer before you write the amount. And carry $60 to $100 in fives, tens and twenties, because the customer handing you $700 for a $640 job is going to wait for change.

Cash is income, and no 1099 arrives to remind you

A card payment shows up in a processor statement. A check shows up on a bank line. Cash shows up nowhere unless you put it there — and that is the only difference the IRS recognizes. Payments in cash are reportable income exactly like every other payment, whether or not a customer ever issues you a 1099-NEC.

The same goes for sales tax. If the work would have been taxable paid by card, it is taxable paid in cash, and the tax collected in twenties is money you hold on the state's behalf until you file. Whether labor is taxable at all depends on your state and sometimes on the job type, so ask your state revenue department.

The cash log that turns a stack of bills into a record

One running list, on paper or in a spreadsheet, covering only cash. Every payment in, every deposit out, a balance you can compare against what is actually in the envelope.

The line that is missing from that table is the one to be careful about: paying the supply house out of the collected cash before it is deposited. Do that and you have hidden income and a deduction in the same move. Deposit the cash, then buy the material with the business card or a check, and both sides of the transaction exist.

Depositing it, and the one thing you must never do

Deposit on a rhythm — end of week, or whenever the envelope passes an amount you would not want to lose. Cash in a truck console is uninsured, unrecorded, and easy to spend on lunch. Cash in the business account is provable.

Two things worth knowing about the bank. Many business checking accounts include a monthly cash-deposit allowance and charge a fee per hundred dollars above it, so ask what yours is before your volume grows into it. And banks file a currency transaction report on cash deposits above a federal threshold — that report is the bank's job, not yours, and a legitimate deposit is not a problem.

Splitting a deposit to stay under the threshold is. Breaking $12,000 into three trips is structuring, a federal crime in its own right, and banks are trained to spot the pattern. Deposit the real amount on one slip and there is nothing to explain.

When a cash payment tops $10,000: Form 8300

Businesses that receive more than $10,000 in cash in one transaction, or in related transactions, generally have to report it on IRS Form 8300. The IRS says the filing is generally due within 15 days. It also requires a written statement to each named person by January 31 of the following year, subject to limited exceptions. Related-transaction rules can mean two payments on the same job add up to a filing.

A $14,000 cash draw on a kitchen remodel is rare but not imaginary. If it happens, read the current instructions or call your CPA that week — the mechanics, the e-filing requirement and the definitions get updated, and this is not a rule to reconstruct from a forum post.

The cash discount that costs more than the card fee

The customer asks what you would do for cash. The honest version of the answer is arithmetic. Take a $2,000 job, with card processing at a typical 2.9% plus 30 cents:

You gave away $200 to avoid $58. If a cash discount makes sense for you, size it to the fee you actually save — a percent or two, published the same way for every customer, and shown on the paperwork as a discount line. That is a legitimate pricing choice, and different from what the customer is usually hinting at.

The hint is a lower price that never reaches the books. Say yes to that and you have written a receipt for one number while reporting another, which is the version an auditor finds first. It also costs you things you will want later: two years of understated revenue is the income a lender looks at when you finance a truck, and the customer with an off-book price is the one who cannot produce a paid invoice at a warranty claim or a home sale. One price, one record, whatever the payment method.

Paperwork you should not be writing from memory at the curb

Cash receipts go missing because they get written twice — once as the price you gave, then again as a note in a driveway. In DoneQuote the line items and totals already exist from when you priced the work, so recording it as paid in cash is a change to a field rather than a document rebuilt from memory. The number the customer takes away is the number that was already in the file, which is what you want if anyone asks about that job a year from now.

Cash is not the risk. An undocumented payment is.
