There's a [custom date range] link below the year drop down field.
You can set a custom start and end date there.
- Ensure you have checked the "Check to use the custom period" checkbox
- And use this date format "dd.mm.yyyy"
Using this setting, only sales within your custom time period will be calculated.
I'm not as far along as pescadorloco69 apparently, but it's on my list when I get closer...
When specifying the date ranges are they in UTC? If so, is there a way to specify a timezone when specifying the ranges? For example, a trade "after midnight" of the tax year (in local time) in question but "before midnight" in crypto (UTC) should not be included in that tax year. At least that's what I would expect.
