The IRS Backup Withholding Threshold Tripled to $2,000: What Changes in Your Payout

Backup withholding is the one part of getting paid that catches contractors off guard, because it does not show up as a line item on an invoice. It shows up as a smaller deposit than the invoice said, with no warning first. Under the One Big Beautiful Bill Act, the dollar threshold that governs when this can happen tripled for 2026, from $600 to $2,000 per payee per calendar year.

What backup withholding actually is

A client paying you does not normally hold anything back. They pay the invoice in full, and you handle your own taxes on that income at filing time. Backup withholding is the exception. If a payer cannot match your name to a valid taxpayer ID number, the IRS requires them to withhold 24 percent of the payment and send it straight to the government instead of to you.

That 24 percent rate has not changed. Under Section 70433 of the OBBBA, effective January 1, 2026, what changed is the size of the relationship that has to exist before this rule can apply at all: the $600-per-payee threshold that triggered 1099 reporting, and with it the conditions for backup withholding, moves to $2,000.

The trigger is a missing W-9, not a missed payment

Raising the dollar threshold does not change the actual mechanism. Backup withholding never happens just because a payment is large. It happens because a payer has a payment that requires 1099 reporting and does not have a valid taxpayer ID number on file for the person receiving it, usually because a Form W-9 was never collected, or the name and number on it do not match IRS records.

	Before 2026	2026
1099 reporting threshold, per payee per year	$600	$2,000
Backup withholding rate on a mismatched TIN	24%	24%
What prevents it	A valid W-9 on file	A valid W-9 on file

Under the old $600 line, almost any ongoing contractor relationship crossed into 1099 territory fast, which meant a missing W-9 became a live risk quickly. At $2,000, a lot of smaller or occasional engagements never reach the point where the payer’s reporting obligation, and the withholding risk that rides along with it, kicks in at all.

One form removes the risk for good

None of this is a reason to treat a W-9 as optional once a relationship is worth collecting one for. A payer who has your W-9 on file with a name and number that matches IRS records has no basis to withhold anything from you, no matter how the payment gets categorized. A payer who does not have it is required to withhold the moment your payments cross into reporting territory, and by then the deposit has already landed short.

The screenshot below is from an August 2026 accounting-industry guide walking through the threshold change and the W-9 timing it recommends: collect the form before the first payment, not after.

If you invoice through BillyPaid, every client relationship is already tracked by name and by payment history, which makes it easy to see exactly which clients are worth a W-9 request before the total for the year gets anywhere near the line that matters.
