·Why we're building this
We got tired of spreadsheets too.
Crypto tax math is the same trap everywhere: hundreds of trades, a price for every date, and a total you can't defend. We built an engine that does that math and shows its work — tuned to the CRA's rules, so what you review are your own numbers, not a generic export.
Adjusted Cost Base (ACB)
The rule that decides your bill
The CRA requires the Adjusted Cost Base method — a running weighted-average cost per coin, recalculated on every purchase. As of 2026, gains above $250,000/year are taxed on 66.67% of the amount instead of 50%.
Today
Now tuned for Canada
Adapted to the CRA rules — with the full calculation open for you to check, line by line.
How it works
01
Connect read-only
Link your exchange with a read-only API key. No withdrawal permission — ever. Keys with trading rights are rejected before being stored.
02
We organize and calculate
Every trade classified and converted at the correct historical price, with the full calculation visible — never a black box.
03
You review and report
Check every line, download your summary, and file with the CRA yourself. The final control is always yours.
Is this you?
The situations we solve
Sold this month
You took profit and don't know how much you owe — or by when.
Paid in crypto
Part of your income arrives in USDT and needs to be reported properly.
Spreadsheet hostage
You track everything by hand and dread the end of every month.
Multi-exchange
History scattered across platforms, afraid of missing something.
Before / after
What actually changes for you
Doing it by hand
- Hours in spreadsheets, every single month
- Hunting the historical price of every trade date
- Fear of one wrong number ruining the total
With DeclararDeCripto
- Minutes — the import is automatic
- Historical prices fetched for you
- Every line reviewable before you file
Honest comparison
DeclararDeCripto vs. doing it by hand vs. a traditional accountant.
Each path has its place. For complex cases you'll still want an accountant or tax advisor. For the routine reporting, compare what each one delivers.
| Criterion | By hand | Accountant | DeclararDeCripto |
|---|---|---|---|
| Time per period | 4–10 hours of spreadsheets | 1–3 hours on your side, plus theirs | Minutes — import, classify, calculate |
| Cost | Free, but it's your time | Hourly billing, every month | One flat subscription in USDT |
| Risk of errors | High — one wrong price ruins the total | Depends on what you hand over | Low — automatic classification + your review |
| Exchange coverage | Export CSVs by hand, one by one | You still gather everything | Read-only API import — Binance today |
| Self-custody wallets | Block explorer, address by address | You still gather everything | In development — public address only, no seed, no key |
| Conversion to CAD | Hunting historical prices by date | You deliver it — or pay extra | Automatic, at each trade's date |
| Monthly tax math | Your formula, your risk | Done, but you pay the hour | Calculated with the method open to audit |
| Who controls the filing | You, alone | A third party acts for you | Always you, with the CRA |
Questions you should ask
Crypto and taxes cause anxiety. Let's get straight to the point.
Before anything else, the four most common doubts — answered directly, no runaround.
“Will you have my keys?”
Never. Read-only exchange access with no withdrawal permission — keys with trading or withdrawal rights are rejected before being stored. We never ask for a seed phrase or private key.
“What if I only use one exchange?”
If it's Binance, you're covered today. Other exchanges and wallets are in development — and the order they arrive follows what users ask for.
“Does this replace my accountant?”
It doesn't — it complements. For simple cases the tool may be enough. For complex ones you'll still want an accountant or tax advisor — and the organized calculation, with the math open, saves them hours and saves you money.
“Are you the CRA?”
No. A private, independent service with no ties to any government body. We never file anything in your name: you review and file through your own access.
The fears nobody talks about
Crypto + taxes = anxiety. Let's talk about what nobody says out loud.
These are the questions that cross everyone's mind. Direct answers, no runaround.
“If I use the tool, will the CRA track me?”
No. We're a private tool with no ties to the CRA. We don't share your data with any government body. The numbers stay in the tool, under your control — the CRA only sees what you yourself decide to file.
“What if I should have reported crypto in earlier years?”
A common — and legitimate — fear. DeclararDeCripto organizes your reporting going forward; it doesn't amend old filings. If you suspect something was missed in past years, the right path is a local accountant or tax advisor. Reporting you is not our role — and never will be.
“What if the rules change midway?”
A fair concern: tax rules do change. We monitor the rules that affect the calculation and update the engine — at no extra cost to subscribers. You get a notice explaining what changed and what to do.
“I'm not even sure I owe anything. Will I pay for nothing?”
Connect read-only and the summary shows whether there's tax due and how much — with the math open, line by line. If there's nothing due, you'll see it in plain words. And you can cancel anytime; there's no lock-in.

Guided review
“I'm afraid of classifying something wrong”
Deposit, withdrawal, swap, transfer between your own wallets — each has a different tax treatment.
A review desk that explains every classification. When the tool isn't sure, it asks — it never decides in the dark.
Clear answer
“Maybe I don't even owe anything”
Small sales every month and the eternal doubt about whether tax is due.
The summary says, in plain words, whether there's tax due and how much — never a black box.
In development
“I use another exchange or my own wallet”
Coinbase, a cold wallet, a TRON address — Binance isn't your only source.

How Canada actually taxes crypto
Compliance · Adjusted Cost Base (ACB)
The rule that matters most: The CRA requires the Adjusted Cost Base method — a running weighted-average cost per coin, recalculated on every purchase. As of 2026, gains above $250,000/year are taxed on 66.67% of the amount instead of 50%.
Relevant filing: Schedule 3.

Quick answers
How much does it cost?
You get 7 days free first, no card. Then 9 USDT per month, or 72 USDT per year (that's 6 USDT/month) — less than a fraction of an accountant's hour for the whole month organized. Payment in USDT (TRON/TRC20 network) inside the app, and the launch price stays locked while your subscription is active. Cancel anytime.
Will you have access to my money or my keys?
No. Exchange access is read-only, with no withdrawal permission — keys with movement rights are rejected before being stored. We never ask for a seed phrase, private key or any credential that could move funds. The keys and the money stay with you, always.
Will you file my taxes for me?
No, and that's deliberate. The tool organizes the data, classifies operations, converts values to CAD and calculates your numbers. The final decision and any filing with the CRA stay with you, through your own access. That keeps you in control and keeps third parties from acting in your name.
Does this replace my accountant?
It doesn't — it complements. For simple cases, the tool may be enough. For complex ones — companies, high volume, estate planning — you'll still want an accountant or tax advisor. The difference: the organized calculation, with the math open, saves your accountant hours and saves you money.
Are you the CRA?
No. We're a private, independent service with no ties to the CRA or any other government body. We file nothing in your name and share your data with no one.
Is Binance enough to start?
Today Binance is the only connectable source — and it's where we recommend starting. Other exchanges and self-custody wallets are in development and will be added at no extra cost to subscribers. If your main source isn't here yet, write to us: integration order follows user demand.
