About the 1099-K Checker

The 1099-K Checker is a free, fast, no-signup tool for online sellers. From your gross platform payments, transaction count and costs it answers three questions people usually have to piece together from scattered, often out-of-date articles: whether a platform is required to send you a federal Form 1099-K, what changes if you report your selling as a hobby or a business, and roughly how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 over $20,000 and more than 200 transactions, to a $600 rule that was enacted but never took effect, through several years of IRS transition relief, and finally back to over $20,000 and more than 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

The thresholds the checker uses live in a single dated data module, and that date is shown on the home page next to the threshold table. The current figures were verified 2026-09-23. The guides also quote some of those figures in their own text; the table's date is the one to check. 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 and no content farm, and nothing you type into the tool is recorded. Like most sites, we do record how pages are used, such as visits, scrolling and whether a tool showed a result; the privacy policy lists exactly what is recorded and when we ask first.

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.
