Q: Where does a virtual mailbox go on Sch C?

A virtual mailbox belongs on Line 18, office expense. A virtual mailbox or registered business address is a recurring mail handling service, so it belongs in office expense on line 18. You are paying for scanning, forwarding and the right to use an address, not for space you occupy, which is why it is not rent. A registered agent fee is usually grouped the same way, though some preparers itemise it in Part V as a filing cost.

What a virtual mailbox is confused with

Line 20b, rent or lease of other business property: If the plan includes use of an office or a desk you can actually occupy, the occupancy part is business property rent on line 20b and only the mail service stays on line 18.
Line 27a, other expenses: State filing and registered agent fees are often itemised separately in Part V and carried to line 27a, which is fine as long as the same fee is not also inside office expense.
Line 23, taxes and licenses: The state's own LLC registration or annual report fee is a licence cost on line 23, not part of the mailbox service fee.

$29 a month for an Anytime Mailbox plan with scanning
$99 a year for a registered agent service for the LLC
$19 a month for a virtual address used on invoices and state filings
