Direct Answer

The money move is to make the landlord appeal the assessment — or get the right to do it yourself — and to cap how property taxes flow through to you, because tax pass-throughs are one of the largest and most beatable line items in your CAM. A successful assessment appeal commonly cuts a property's taxes 5–25%, and in over-assessed or post-sale situations even more. On a building where your pro-rata tax share is $60,000/year, a 15% reduction is $9,000 back in your pocket every year for the rest of the lease — recurring, compounding savings most tenants never pursue because they assume taxes are fixed. They aren't.

Three levers do the work: (1) a lease obligation that the landlord must contest assessments you reasonably request (or grant you the right to appeal in the landlord's name), (2) a "Proposition 13"-style protection so a building sale doesn't reset the assessment and spike your share, and (3) exclusion of new special assessments, betterment districts, and the landlord's income/transfer taxes from the pass-through. The trap is the standard landlord clause that passes through "all taxes and assessments" with no appeal duty, no sale protection, and no exclusions — leaving you to fund every reassessment, special district, and post-sale spike.

Why the Tax Pass-Through Is Beatable

Property assessments are estimates, and estimates are wrong constantly. CBRE and tax-appeal specialists report that a large share of commercial properties are over-assessed because assessors rely on mass-appraisal models, stale comps, or pre-vacancy values. The most common over-assessment triggers:

When the landlord pays taxes and passes them through, the landlord has little incentive to appeal — it's your money, not theirs. That misalignment is exactly what you fix in the lease.

The Three Lease Clauses That Give You the Right

1. The landlord appeal duty. Target: "Upon Tenant's reasonable written request, Landlord shall contest the assessed valuation of the Property, and any tax savings shall reduce the taxes passed through to Tenant. If Landlord declines, Tenant may pursue the contest in Landlord's name at Tenant's cost, with savings credited to Tenant." This guarantees the appeal happens whether the landlord wants it or not.

2. The Proposition 13 / sale-reassessment protection. In states with acquisition-value assessment (notably California under Proposition 13, and similar dynamics elsewhere), a building sale can reset the assessment to the new, higher purchase price — spiking your tax share through no action of yours. Negotiate: "Tenant's tax pass-through shall not increase as a result of a change in ownership or reassessment triggered by Landlord's sale or transfer of the Property." This is a major save in markets where a single sale can raise taxes 20–50%.

3. The exclusions list. Carve out from the pass-through: special assessments and improvement-district levies (sidewalks, sewers, business-improvement districts), the landlord's income, franchise, estate, gift, and transfer taxes, and interest or penalties from the landlord's late payment. These are not your operating costs.

Cap and Base-Year the Tax Component

Beyond the right to appeal, control the math:

Run the Appeal Like a Pro

When you trigger an appeal — directly or by pushing the landlord — execute it cleanly:

Don't Forget the Reconciliation

Like CAM, the tax pass-through shows up in the annual reconciliation, and that's where to catch errors:

What to Look for in Your Lease Language Before Challenging

Before you spend a dime on attorneys or appraisers, pull your lease and find the tax pass-through clause. The most common structures are:

Key action: Look for a clause that says the landlord *must* contest excessive assessments if you request it. Many standard leases include this but tenants never invoke it. If your lease is silent on who can appeal, you may need the landlord's written consent to file on your own – or you can request they file and share the savings.

How to Gather the Data You Need to Build Your Case

Landlords rarely volunteer their tax assessment details. You'll need to collect:

  1. The property's assessed value – Check your county assessor's website. Compare it to recent sales of comparable buildings in the same submarket. A common red flag: the assessment is higher than what the landlord paid for the building.
  2. Your pro-rata share – Confirm the square footage ratio used to calculate your pass-through. Errors here are shockingly common (e.g., using gross leasable area instead of net rentable area).
  3. The tax bill itself – Request a copy from the landlord. If they refuse, cite your lease's audit rights clause. Most commercial leases give you the right to inspect expense records.

What to look for: If the building was recently sold, the new owner's purchase price often triggers a reassessment to market value. That new assessment may be inflated – especially if the buyer overpaid or included personal property (furniture, equipment) that shouldn't be taxed as real estate.

When to Bring in a Property Tax Appeal Specialist

You can file an appeal yourself, but commercial property tax appeals are technical and jurisdiction-specific. A property tax consultant (not a general attorney) typically works on contingency – they take 25–40% of the savings for the first year only. That means no upfront cost to you.

When it makes sense to hire one:

What to expect: The consultant will pull comparable sales, review the assessment methodology, and negotiate with the assessor. Most cases settle before a formal hearing. If they win a reduction, you get the savings minus their fee. If they lose, you pay nothing. This is a low-risk way to challenge a pass-through without burning your relationship with the landlord.

FAQ

Can my landlord pass through any property tax increase to me? Not automatically. Your lease must explicitly allow property tax pass-throughs, and many leases cap the increase or limit it to a percentage. Check your lease language—if it’s silent on taxes, you may not owe anything.

What if my lease says I pay “increased taxes” but the landlord doesn’t appeal? You can request that the landlord file a tax appeal, or you may have the right to file one yourself if your lease grants that right. Without an appeal, you could be stuck paying an inflated assessment—so push for action or a written agreement to challenge it.

How do I find out if my property’s tax assessment is too high? Look up comparable properties’ assessments on your county assessor’s website. If similar buildings pay less per square foot, that’s a red flag. You can also hire a commercial property tax consultant for a few hundred dollars to do a quick analysis.

Can I challenge the pass-through amount without challenging the assessment? Yes—you can dispute how the landlord calculated your share. Ask for a breakdown of the total tax bill, the base year, and the allocation method. If they use a different square footage or include common areas incorrectly, you may owe less.

What’s a typical cap on property tax pass-throughs in commercial leases? Common caps range from 3% to 5% annual increases over the base year, though some leases have no cap. In strong tenant markets, you can negotiate a cap of 2-4% or even a fixed dollar amount.

How long does a property tax appeal take, and can I get a refund? Appeals typically take 3 to 12 months, depending on your county. If the assessment is lowered, the landlord usually gets a refund for prior years—and your lease may require them to pass that savings to you. Check your lease for a “tax refund” clause.
