Five Things Commercial Property Owners Should Review Before Paying Property Tax Bills
October marks the beginning of property-tax season for California commercial property owners. Annual secured property tax bills are mailed in the fall, with the first installment due November 1 and becoming delinquent after December 10, and late first-installment payments are generally subject to a 10% penalty.
For commercial owners, however, paying the bill is only part of the job.
Property taxes can represent a significant operating expense, and they often affect tenant CAM or operating-expense charges. Before approving payment, owners and property managers should review five things.
- Compare the Bill With Last Year
Don’t look only at the amount due. Compare the assessed value, total tax, special assessments and fixed charges with the prior-year bill. If something changed materially, determine why.
- Compare It With the Property Budget
The actual tax bill gives owners an opportunity to replace an estimate with a known expense. If the property is currently preparing its 2027 operating budget, this is also a good time to make sure future tax assumptions are reasonable rather than simply increasing last year’s number by an arbitrary percentage.
- Review the Leases Before Billing Tenants
Not every commercial lease handles property taxes the same way. Depending on the lease, taxes may be included in rent, separately reimbursed, included within operating expenses, subject to a base year, or allocated according to a tenant’s proportionate share. The lease—not the tax bill—determines what can be charged to the tenant.
- Watch for Supplemental Bills
Annual secured property taxes are not necessarily the entire story. Supplemental assessments may be issued after certain ownership changes or new construction. Because those bills can arrive separately and have different due dates, they should be tracked independently. Some Counties mail supplemental bills throughout the year and therefore may not follow the annual secured-tax payment schedule.
- Calendar the Deadlines
Make sure you check the installent due date. In California most Counties first installment is due November 1 and becomes delinquent after December 10. The second installment is due February 1 and becomes delinquent after April 10. Those dates may sound routine, but a missed deadline can be expensive.
For commercial property owners, good property-tax administration is not complicated. It comes down to reviewing the bill, understanding changes, paying it on time, and making sure tenant recoveries follow the lease.
That small amount of attention can prevent accounting errors, missed recoveries and unnecessary penalties.
