If the Send doesn’t take, you can just paste your clipboard contents back again in a new post window.

If it appears to have been sent, but it’s important, you can paste it into a Notepad .txt file (Ctrl+V) .

If the message disappears into digital limbo or if the recipient at the tax department denies receiving it, you at least have a copy of the original to resend.

If it’s a long tome, copy it at several intervals.
