Fair Rental Value: The Cap That Surprises Pastors at Tax Time

The fair rental value (FRV) cap quietly limits a lot of housing allowance claims. Here's how to calculate it correctly, document it, and avoid losing the deduction.

What FRV is

Fair rental value is the amount your home would rent for, fully furnished, with utilities included, on the open market. It's the third (and often most overlooked) cap on your housing allowance.

If your church designated $40,000, you spent $35,000, but your home would only rent for $28,000 furnished + utilities — your tax-free housing allowance is capped at $28,000. The rest is taxable.

How to calculate it

Find 3-5 comparable rentals in your area on Zillow, Rent.com, or your local MLS. Look for similar bedroom count, square footage, and neighborhood. Add a 10-20% premium for the fact that yours is furnished and includes utilities (real-world furnished rentals add roughly that much).

Document this. A screenshot folder or a one-page memo with the comps, addresses, and your calculation is fine. You don't need a formal appraisal unless your situation is unusual or the numbers are large.

Re-running it each year

Rental markets shift. A comp valid in 2024 may be 30% off by 2026. Take 15 minutes each January to re-pull comps and update your FRV memo.

Stop tracking receipts the hard way.
