© 2026 OpenAccountants. Accounting services and free, source-cited skills.

OpenAccountants is a trading name of Glimpse Ltd, a company registered in Malta. We do accounting and tax work for business owners under a separate written engagement. We are not a US CPA firm and do not perform audits; US returns are signed by a US CPA or enrolled agent named in your engagement. Our free skills and automated outputs are general reference material; using them does not create an engagement or submit a filing.

Free AI skills

Tax and accounting knowledge, in the open.

Contribute a skill

Read our AI skills (tax rules your AI follows), check their sources, or use them with your AI. Each skill shows its author and whether another accountant has checked its method.

Authorship and an independent check are different. Check the applicable period and official sources before using a figure.

What the authorship and review labels mean
Checked by an accountant
— An accountant other than the author reviewed the method of this version — which rules apply, in what order, under what conditions — and publicly stands behind it. Individual figures carry the official source as their authority.
Accountant-authored
— Built and published by a named accountant approved on OpenAccountants. Their licence number is shown when it is on file.
No accountant sign-off yet
— Labelled "Checked against the law" (Every figure is cited to the law and was checked against the statute by an independent review on merge. No accountant has signed it off yet.) or "Sourced from the law" (Every figure is cited to an official source. No accountant has signed it off yet.)
