3 New Methods for Tax Calculation

By popular request, three new methods for tax calculation are now available to all CoinTracking users:

- AVCO - Average Cost
Similar to FIFO, but with the average cost basis for every purchase.

- ACB - Adjusted Cost Base
This special adjusted method can be used in some countries like Canada or Sweden.

- OPTI - Optimized Calculation
This method will always provide the lowest profit.
1) All purchases that are long-term (by default > 1 year) are sold first starting with trades with the highest profit.
2) If there are no more long-term purchases available, short-term purchases (by default < 1 year) will be sold, starting with trades with the lowest profit.

Hi Dominik,

Thanks for implementing these new methods. I noticed an error with the ACB tax reports that should be very simple to fix.

The tax reports show the cumulative gain over multiple years, without subtracting the gain or loss from previous years.

For example, say for DASH I had a capital gain of $1000 in 2017, and $500 in 2018. This means I should get taxed on $1000 of that gain in 2017 and $500 of that gain in 2018. But the current ACB tax reports show a gain of $1000 in 2017 and $1500 in 2018.

It's calculated as if I get get taxed on gains from previous years over and over again.

The solution would be to simply subtract the 2017 gains ($1000) from the total cumulative gains as of 2018 ($1500), and then report the difference as my 2018 gains ($1500-$1000=$500).

Here's a screenshot from CoinTracking to illustrate the problem:

If you need more specific examples I can email you more screenshots from my account.
