In most countries a tax payment that is due counts as a debt so is covered by legal tender laws, which do require that people accept payment in cash. It may not be an option presented to you, but it is usually legally available to you, if someone is trying to enforce a debt such as payable tax.
Note that legal tender laws don't apply to a service or product that has not yet been provided - only debts - and also note that a business that has to enforce a debt and that you pay in cash may decline to do business with you in future.
Finally, note that not all currency is legal tender - for example Scottish bank notes are not legal tender, so you can't insist on paying your debts with them.
In fact, in Scotland, neither are English bank notes. (Technically there is legal tender in Scotland, but only Royal Mint coins, and Bank of England one pound notes, which are no longer circulated).
FYI I'm in France and here cash can only be used for taxes under 300€ [1]
Maybe if you don't pay and they start suing then some other laws allows you to reimburse the debt with cash for any amount.
With that said, I know we have some laws to allow everyone (most people?) to have a free bank accounts ("right to an account" [2]), and some other laws that prevent even the state to seize what you have on a bank account for debt reimbursement if it's lower than a certain amount (565.34€ - it's called the "unseizable amount" [3]).
I don't know if it's possible to freeze bank account as they did in Canada. I'd guess they would have to have approval from a Judge.

As long as you can pay your taxes somehow with cash, I fail to see the problem? The tax office doesn't need to accept cash directly. I don't really see the problem if they delegate handling cash to banks or other institutions as long as no one can be denied access to those.
Not directly, though it works with partner companies that accept cash for an extra fee, with limits on per-payment and per-day payments. [0]

It would seem to be impractical for a non-trivial business to work with the cash payments limits.

In practice that's bullshit and you know it. The .gov, be it state local or fed, has show time and time again that it's not above prosecuting someone for a "failure to X" crime of which the failure was caused by the .gov's own action.
Sure, if you're willing to schlep all the way to the nearest IRS office to you that has a human in it that will take your cash. Which might be hundreds of miles away.
There are good reasons why most people prefer not to pay most things in cash.
Cash & digital can be complementary.
One post office trip per quarter: one money order per vendor, one batch of envelopes mailed.
Monthly online bills will have a negative balance to indicate the credit.
Zero data leaked to payment middlemen.
In the United States you can.
Almost all bills, utility and otherwise, can be paid for in cash at most supermarkets or other money-handling businesses. ("Currency exchanges" in Chicago, or whatever your local equivalent is.)
Also, every utility company I've had serving my last five apartments has had a public lobby where people can make cash payments. I suspect even cell phone bills can be paid with cash at a cell phone company's retail store.
So long as you are on a post-paid account you don't even need this. If you are on a post-paid plan of any sort, it's a debt. You have the legal right (via the Coinage Act) to pay that debt via cash regardless of any systems they might not have setup to do so.
It's a fun game to play sometimes to remind institutions of this fact, and usually rouses some bored corporate counsel from their slumber to first argue with you, then apologize.
Probably doesn't really help build a great business relationship, however.
