C9 AI

T4 / T5 slips

Ask what's on a T4 or T5 slip and see the box it came from.

Upload Canadian T4 (employment) and T5 (investment income) slips as PDFs or phone photos. Ask about a box and C9 AI answers using the slip, with a link to the page it read.

PDFs or photos

Scans and photos are converted to text, keeping box numbers next to their amounts where the image is clear.

Ask about any box

For example: “How much tax was deducted?” or “What's the total interest across these T5s?”

See the source

Each answer links to the quote on the slip, and warns you if a number isn't on that page.

A reading aid, not a filing tool

Keep a client's slips in one workspace and ask for totals instead of retyping each box. C9 AI doesn't fill in or file returns. Photos can be misread, so always check the original slip.
