Bookkeeping software for Canadian sole proprietors, with a T2125 preview built in.

No. Ledg builds a T2125 preview straight from your ledger, every box populated and clickable to the underlying transactions, but you don't file from Ledg. Download the watermarked PDF or CSV zip, or email a signed link to your accountant; they file your T1 (which T2125 attaches to) through their professional EFILE software, or you file it yourself through TurboTax / SimpleTax / WealthSimple Tax. Ledg is the books-and-handoff layer, not a NETFILE app.

Track every commit's tax anyway. Ledg shows your trailing four quarters of taxable revenue against the $30K small-supplier threshold; the day you cross, flip "GST registered" in Settings and Ledg starts producing the GST34-2 line numbers (101 / 105 / 106 / 108) you paste into CRA My Business Account. The historical period stays unregistered correctly so you don't accidentally collect or claim ITCs you weren't entitled to.

Yes. You start a new corp record under the same login when you incorporate, and your sole prop history stays intact for T1 reference. The dashboard switches between corps with a picker. The T2125 preview keeps working for the years you operated as a sole prop, even after you incorporate.

Track total km and business km in Settings > Tax Profile. Ledg builds T2125 Chart A (CCA on the vehicle, with the right class, half-year rule, and AccII multiplier), Chart B (interest, capped at the 2026 rate of $350/mo), and Chart C (lease, capped at $1,100/mo for 2026), then prorates everything by business-use percentage. Class 10 / 10.1 / 54 / 55 picker per vehicle handles the EV vs ICE vs over-the-cap-cost distinction.

Yes, both methods. Pick simplified flat-rate or detailed (rent, utilities, insurance, property tax, mortgage interest, repairs, other). Detailed mode applies your business-use floor area ratio. Both modes apply the "no loss" rule, which caps your home office deduction at net income before home office; any excess carries forward automatically year-over-year.

It builds the line-by-line numbers correctly: every commit routes through a classifier first so Owner Draw, Loan, Transfer, and Tax Remittance entries can never pollute Part 4 expenses. Capital assets route to Area A. Vehicle entries route to Chart A. Meals are pre-multiplied by 50% for s.67.1. That said, every preview ships with a banner saying "This is not a filed return" because line items like 8230 recapture, 8290 reserves, 8590 bad debts, and partner-share splits need accountant judgment. Your accountant uses the preview as the starting point, not the final return.

Three formats. PDF: 6-page watermarked preview covering Part 1 identification, Part 3 income, Part 4 expenses, Part 5 net income, Part 7 home office, Area A CCA, Charts A/B/C vehicle, Part 9 equity. CSV zip: summary + per-entry detail + warnings + README. Email: 540px Inter card with the headline numbers, your optional note, and a 7-day signed Supabase Storage link to download the PDF/CSV from secure storage.

Yes. If you're earning money as a freelancer and haven't formally registered a business, you're a sole proprietor by default in Canada. Ledg treats you as a sole prop. You can add a business name in Settings later if you register one, but it's not required to start tracking books and preparing for T1 + T2125.
