One hosted ACA e-file check key — $499 for 12 months

$499 for 12 months is one payment for one key for the hosted pre-check of a 1094-C/1095-C XML file. The buy button is that payment. The free check and the paid check are different. With the key box empty, Check file runs 15 checks in this browser and does not send the file. Those 15 look at the manifest, the 1094-C, the 1095-C, the employer name and EIN, the tax year, the form count, the employee SSN, the offer code, the safe-harbor code, and the ZIP. With a key, Check file sends the XML (limit 5 MB) to the hosted checker. That checker runs the open-source rule set, 46 rules, and a valid key returns every finding from that run instead of the first 25. Each finding has a code, a message, and a fix note when the checker sends one. The response also includes the line "We do not keep your file. It is checked and then thrown away." This does not file a return and does not validate the file against the official IRS schema. The IRS decides. Refunds are not offered.

Sample not ready. This is a pre-checker, not a filing agent.

What the paid product is

The paid product is that one key, at the price above. It is not a second tool and it does not include the IRS rejection-code decoder. The extra you get is the hosted run: the 46-rule check, with every finding returned, instead of the 15 checks that stay in the browser. The key does not file the return, and it does not change what the IRS decides.

Check a file in your browser

Copy the XML text of your IRS health-coverage e-file (the 1094-C and 1095-C forms together) into the box, or choose a file. Add your paid key if you have one.

Paid key (optional)

With a key, this box sends the file to the hosted checker and lists every finding from the 46-rule run. Without a key, only the 15 checks run in this browser and nothing is sent.

Paste a file and press Check file to see what it finds.

Passing every check here does not mean the IRS will accept your file. It means these 15 checks did not find a problem. The full open-source tool behind this page runs 46 checks and can validate against the real IRS schema if you add those files yourself.
