Form 8300 Calculator for Watch Dealers

How it works

Federal law requires any business that receives more than $10,000 in cash in one transaction, or in related transactions, to file IRS Form 8300. For watch dealers the hard part isn’t the threshold. It’s knowing which payments count, and noticing when a buyer pays in pieces. The checker classifies each payment by its form, adds up only what the IRS treats as cash, and finds the payment that pushed the total over the line.

What counts as cash

Currency always counts, US or foreign.
Cashier’s checks, bank drafts, traveler’s checks and money orders with a face amount of $10,000 or less count when received in a designated reporting transaction. That includes the retail sale of a consumer durable, defined as tangible personal-use property that lasts at least a year and sells for more than $10,000. A luxury watch fits. They also count in any sale if you know the buyer is trying to avoid the report.
An instrument over $10,000 face is not cash.
Wires, personal checks and cards don’t count.

The aggregation rules

Payments from the same buyer within 24 hours are combined. Payments further apart are still combined if you know, or have reason to know, they’re part of a series of connected transactions. For installment payments on one sale, add the cash received within one year of the first payment. The filing is due 15 days after the payment that takes the total over $10,000, and once you file, the count starts again. Choose “One deal / series” above for installments and connected buys, or “Unrelated buys” to combine only payments that could fall in the same 24 hours.

A worked example

A buyer agrees to $18,500 for a watch. On October 20 they hand over $6,000 in currency. On October 22 they bring a $5,500 cashier’s check and wire the remaining $7,000. The wire doesn’t count. The cashier’s check does, because it’s under $10,000 face in a consumer-durable sale over $10,000. Reportable cash is $11,500, crossing the line on October 22, so Form 8300 is due by November 6, and the buyer’s written statement by January 31 of the next year.

Had the same buyer paid with one $12,500 cashier’s check, only the $6,000 in currency would count. The full guide, Form 8300 for watch dealers, covers e-filing, the buyer statement, and penalties.

Frequently asked questions

Does a cashier's check count as cash for Form 8300?

Sometimes. A cashier's check, bank draft, traveler's check or money order with a face amount of $10,000 or less counts as cash when you receive it in a designated reporting transaction, which includes the retail sale of a consumer durable such as a watch priced over $10,000. A single instrument with a face amount over $10,000 is not cash, because the bank that issued it already reports it.

Do wire transfers or credit cards count toward the $10,000?

No. The IRS says a wire transfer is not cash for Form 8300, and personal checks drawn on the writer's own account are not cash either. Card payments are not currency or a monetary instrument, so they don't count.

When is Form 8300 due?

Within 15 days of receiving the cash payment that brings the total over $10,000. If the 15th day falls on a Saturday, Sunday or legal holiday, it is due the next business day. You also owe the buyer a written statement by January 31 of the following year.

What if the buyer pays in installments?

Add up the cash payments for the same transaction. If they total more than $10,000 within one year of the first payment, you must file within 15 days of the payment that pushed the total over. After you file, a new count begins. Payments more than 24 hours apart still combine if you know, or have reason to know, they are connected.
