About the 1099-K Checker
The 1099-K Checker is a free, fast, no-signup tool for online sellers. From your gross platform payments and transaction count it answers three questions people usually have to piece together from scattered, often out-of-date articles: whether a federal Form 1099-K will be issued to you, whether the IRS treats your selling as a hobby or a business, and roughly how much self-employment tax your profit might carry. It runs entirely in your browser; nothing you type is sent anywhere.
Why a whole tool for one form
Because the rules around this one form changed three times in four years, and most of the internet did not keep up. The reporting threshold went from $20,000 and 200 transactions, to a proposed $600, through several years of IRS transition relief, and finally back to $20,000 and 200 transactions under the One Big Beautiful Bill Act in 2025. An article written in 2023 confidently tells you the wrong number for 2025. A tool that applies the correct year's rule, and shows its work, is genuinely more useful than prose that ages badly.
Freshness is the point
Every threshold on this site lives in a single dated data module, and that date is shown on the page next to the numbers. The current figures were verified 2026-07-22. When the IRS or the Social Security Administration announces a change, the table and its date are updated together, so you can always see how current the answer you are reading is. We would rather show you the date and let you judge than present a number with no provenance.
Who runs it
The 1099-K Checker is operated by Crossroads Technologies LLC, a small independent studio that builds focused, single-purpose web utilities. It is one of a small family of reseller math tools that share a look and a standard of care. There is no account system, no content farm, and no data collection inside the tool.
An important limit
This tool produces estimates for planning. It is not tax advice, it does not file anything, and it cannot see the full picture of your finances. It computes one specific tax, self-employment tax, and it applies the general federal rules; it does not calculate your income tax or account for state thresholds, credits, or deductions beyond the costs you enter. For decisions that matter, confirm with the IRS or a qualified tax professional. Reach us through the contact page.
