How does the landlord intend to pay tax?
I'm a landlord who accepts crypto.
You can pay tax with a shift payments visa card via coinbase. In general, you pay through an intermediary that swaps it for you, or cash out just what you need to pay tax when you need it.
Also being a little cynical, some landlords may be up for getting rent in an anonymous crypto like zcash and forgetting to pay the income tax on it.
