The report card
Best for banks and apps that want to embed tax filing
Column Tax is white-label US tax filing that banks and apps put inside their own products. Individuals cannot sign up directly, no prices are published, and the company has announced it is being acquired by Aiwyn.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | No price is published; terms and any fee to the taxpayer depend on the partner. |
| Free plan and trial | F | Individuals cannot sign up directly, and no free plan or trial is listed. |
| Features | C | Embedded filing, expert review and an API cover US federal and state returns with Form 1040 income, but through a partner only. |
| Ease of use | C | Reached only through a partner's account, and no store rating is on record. |
| Platforms and integrations | B | Web only, but it works through an API that partners connect to. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Column Tax is for
- Fits if you run a bank or app and want filing inside your product
- Makes sense if you need expert review and audit support for your users
Who it is not for
- Not for you if you are an individual, as filing is only available through a partner's account
- Tight if you want a price, as none is published and pricing is sold through a demo request
- Watch out: the company announced its acquisition by Aiwyn, so packaging may change
- Skip it if you file outside the US, as it covers US federal and state returns
Good to know

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
The plain part of Column Tax you could make: forms. What surrounds it you could not. The 2 things listed below take a company, not a weekend.
That makes this kind of software worth paying for, not this one in particular: 106 of the 127 other accounting and invoicing tools grade higher.
What you could make
- Forms: an app builder makes this well.
What you could not
- An API that other software can build on.
- What a company asks for before it lets staff use something: SOC 2.
What this rests on. Column Tax’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
