Questions to ask before you pay
- Does the price include the pro forma Form 1120 as well as Form 5472?
- Who reviews the forms: software, an accountant with a PTIN, or a CPA? Is that person named?
- Does the service send the forms to the IRS by fax, or do you have to send them? Do you get a fax confirmation?
- What does it cost to file for earlier years you missed?
- Does it file Form 7004 if you need an extension, and is that extra?
- What happens if your LLC had transactions that the basic package does not cover?
How we chose these services
A service is listed only if its own website shows a public price, says it works with foreign-owned LLCs, and could be read by our checking script under the site's own rules on the day we checked. Affiliate programs and commissions play no part. One well-known service, 5472 Direct, is missing from the table this time only because our checker could not load its site on the day we read the others; we will add it when we can read its current price. How we make money lists which services might pay us in the future.
