How to Bill Tenants for Utilities (RUBS) Without Overpaying Tax

A walkthrough of passing a shared utility through to your tenants the right way — bill it from the expense so income and the deduction are created together and you never overpay tax.

What this video covers

The right way to pass a shared utility through to your tenants — without accidentally overpaying your taxes:

  • Record the bill first — get the utility expense on the books (deduction)
  • Split it across the leases — evenly, by square footage, or custom
  • Charge the tenants — each share posts to their portal alongside rent
  • Track recovery — see billed vs. recovered at a glance

The order matters: record → split → charge. Do it that way and the income and the deduction are created in the same action — they can never drift apart, so a pure pass-through nets to zero and you keep the money you were never meant to owe.

Frequently Asked Questions

What is RUBS (ratio utility billing)?

RUBS — a Ratio Utility Billing System — is how landlords recover a shared, master-metered utility (like one water meter serving several units) by splitting the bill across tenants, typically evenly, by square footage, or by a custom amount per lease. It's the standard way to pass through a utility when there's no separate meter per unit.

Is utility reimbursement from tenants taxable income?

Yes. When you recover a shared utility from your tenants, the money they pay you back is rental income and goes on Schedule E. The key is to also record the utility bill itself as a deductible expense — when both are on the books, a pure pass-through nets to roughly nothing. If you skip the expense, you pay tax on money you never kept.

How do you split a utility bill between tenants?

Bill it from the recorded expense and split it across the active leases — evenly, by square footage (fairer when units differ in size), or by custom amounts. Because every share is a slice of a known bill, the split can never exceed 100%, which is the guardrail RUBS is supposed to have and rarely does on a spreadsheet.
