Tax Reporting

ACB tracking and T1135 reporting, without the spreadsheet.

Updated Mar 29, 2026·

Tax season for self-directed investors usually means digging through brokerage statements, filling in spreadsheets, and hoping you didn’t miss a trade. If you’ve ever tried to calculate your adjusted cost base across multiple accounts, you know how tedious it gets.

Greenline tracks it for you. Upload your statements and Greenline maintains your ACB and flags T1135 reporting requirements, so you’re not scrambling in April.

Adjusted cost base tracking

Your adjusted cost base (ACB) is what you need to calculate capital gains or losses when you sell an investment in a non-registered account. It sounds simple, but it gets complicated fast when you’re making regular purchases, reinvesting distributions, or transferring between accounts.

Greenline tracks your ACB across your non-registered accounts based on the transaction history in your uploaded statements. You’ll see:

  • Per-holding ACB: the adjusted cost base for each position
  • Unrealized gains/losses: what you’d owe (or could claim) if you sold today
  • Transaction history: the buys, sells, and distributions that make up your cost base

T1135 foreign property reporting

If you hold more than $100,000 in specified foreign property at any point during the year, you’re required to file a T1135 with the CRA. This includes US-listed ETFs, US stocks, and international holdings in your non-registered accounts.

Greenline tracks your foreign property value and lets you know when you’re approaching or have crossed the $100,000 threshold. It also helps you gather the information you need for the T1135 form: cost amount, income earned, and gain or loss on disposition.

Does this apply to registered accounts?

ACB tracking matters most for non-registered (taxable) accounts, since registered accounts like TFSAs and RRSPs are tax-sheltered. The T1135 also only applies to property held outside registered accounts. Greenline focuses tax reporting on the accounts where it counts.

Can I use this instead of a tax professional?

Greenline gives you the data. It tracks your ACB and foreign property values based on what you’ve uploaded. For filing your actual tax return, you should still work with a tax professional or use certified tax software. Greenline makes their job easier by giving you organized, accurate records instead of a shoebox of statements.
