Feather

What it does

Feather is a web-based AI tax assistant for CPAs, enrolled agents, tax attorneys, and tax and accounting teams. Users can ask questions about federal and state tax issues, analyze a client scenario against tax authority, and receive answers with citations to primary sources. Its stated coverage includes IRC Title 26, Treasury Regulations, IRS guidance, Tax Court opinions, 50 states, DC, and five territories; the knowledge base is updated weekly.

For client work, Feather can parse documents such as K-1s, W-2s, 1099s, trial balances, and returns into reviewable fields; work with client files in projects; and draft cited memos, client letters, executive briefs, and IRS correspondence. It also reviews prepared 1040 returns by comparing lines with source documents and flagging inconsistencies or open questions. Users can try three questions, then start a seven-day Pro trial. The product is not presented as a DIY filing tool for individual taxpayers, and 1040 tax preparation with Sheldon is described as coming soon.

The Pro plan is listed at $99 per user per month and includes 10 tax reviews per billing cycle; the free trial includes three. The page also lists unlimited chats and email/cloud-drive intake. Students may access Feather at no cost with a valid .edu email, with limits and eligibility to confirm. Tax-preparation software connections are described as coming soon, not currently available.
