Mining records for Canadian crypto tax reporting

Crypto mining means using computers to check and bundle transactions for a blockchain network in return for newly created coins and transaction charges. For tax purposes, the Canada Revenue Agency treats mining differently from simply holding or trading coins. According to the agency, mining is likely a business given the scale and resources involved, such as dedicated machines, steady electricity and ongoing work. That label matters because a business keeps books, reports business income and may claim certain costs. A hobbyist with one old laptop and a large rig in a rented unit may both be asked the same question: is this a business? The answer shapes which records you need from the first day, so it is worth settling early.

The agency explains how the income is counted. New coins that a miner receives, along with transaction charges collected for the work, are included in business income at the time they are received. Each receipt therefore creates a record. The agency's books-and-records page says the entry should show the number of units, the date and the Canadian-dollar value at that moment. A miner might receive many small payouts from a pool in a single month, so the log grows quickly. Business income is then reported with the agency's guide T4002 for self-employed business and professional income. Mining activity also appears on the agency's list of things that must be recorded, so the log is not optional once the work is a business.

Imagine a man named Tomas who runs three machines in his garage. At the start of the year he opens a spreadsheet and a folder. Each time his pool sends a payout, he adds a row with the date, the units received and the Canadian-dollar value taken from a dated source he notes in the next column. He saves the pool's statement as a file beside it. When he installs a new machine, he stores the invoice and writes the model and the day it went into use. In the spring, when he prepares his return, he does not search old chats and screenshots. Everything he needs is already sorted by date, and he can answer a question from the agency in minutes.

Several traps appear in practice. The first is recording only the coins, without the Canadian-dollar value on the day they arrived. The second is losing pool statements when an account closes or a service shuts down. A third trap is mixing personal wallets with the mining wallet, which makes it hard to tell income from a simple transfer. Equipment is another weak point. According to the agency, mining equipment such as ASIC miners and GPU rigs may qualify for capital cost allowance in class 50, and a claim needs proof of purchase and use. Without invoices, dates and notes, the deduction is hard to support later, even when the machines are plainly in use.

A few checks can be done alone with public sources. Does every payout in the wallet history match a row in your log? Does each row show units, date and the Canadian-dollar value at that time? Are invoices for machines, cooling and power stored with a note on how each was used? Is the mining wallet kept separate from the wallet you use for daily spending? Is the log backed up in a second place? The agency's crypto guide and its tax tip on reporting crypto income when carrying on a business describe what to keep. Reading both pages before filing helps you see which of your records are missing, while there is still time to rebuild them from exchange and pool histories.

The Canada Revenue Agency publishes its guidance on its own site, and the pages cited below are the place to confirm current wording. This article cannot decide whether your mining counts as a business, how to treat a particular machine, or how provincial or sales tax rules apply to you. A tax professional or the agency itself can answer those questions for your situation. Keep records for the period the agency requires, and check its pages for that period, since rules can change. This page is general education about record keeping, not tax, legal or financial advice. Read the official pages before relying on any summary, including this one, and bring questions to the agency.

• Log every receipt with units, date and the Canadian-dollar value at that time
• Keep invoices and use notes for mining equipment, since a capital cost claim needs proof
