Can a Landlord Deduct Unpaid Rent from a Security Deposit?

Unpaid rent is a common lawful deduction, but amounts must be correct. Learn what to verify (rent ledger, proration, fees) and how to dispute inaccurate rent claims.

1 min readUpdated January 2026

Many states allow landlords to apply security deposits to unpaid rent. Disputes usually happen because of incorrect ledgers, improper proration, or added fees that aren't actually owed.

When the charge can be legitimate

  • Rent was actually unpaid for a specific period
  • Proration is correct through the move-out/surrender date
  • Amounts match the lease and payment history

Red flags

  • No rent ledger or unclear accounting
  • Charging rent beyond the date you surrendered the unit/returned keys
  • Adding fees that aren't supported by the lease or documentation

What to ask for

  • Rent ledger showing charges and payments
  • Lease clause showing rent amount and due date
  • Move-out/surrender documentation and key return date

How to dispute

  1. Request a rent ledger and confirm the dates/proration.
  2. Dispute any charges after surrender/possession return (case-specific).
  3. Ask for documentation of any fees added.

Start with the dispute template, then escalate to a demand letter if the landlord won't correct it.

Tip: Use the Deduction Checker to sanity-check totals and request documentation for every line item.
