Short-Term Rental Host Occupancy Tax Audit Response

The situation

Maria hosts two Airbnb units in a mid-size California city. She gets a letter from the city's finance department: an occupancy-tax compliance review, requesting proof that transient occupancy tax was remitted for the last three years. She knows Airbnb collects "some" taxes automatically but has no idea which specific stays were covered versus which she was supposed to file herself, and the city's letter cites California's new SB 346 data-sharing authority as how they identified her.

Who receives this

Airbnb/VRBO hosts (individual and small multi-property operators) who receive a local occupancy-tax audit, compliance review, or delinquency notice.

Why the agency will not advise you

Cities buy purpose-built monitoring software to identify and audit hosts; the platforms themselves have no incentive to help a host reconstruct a multi-year remittance history once an audit letter arrives; generic tax-filing apps stop at "here's your Schedule E," not "here's your response to the city."

Key facts, with sources

• Airbnb and VRBO automatically collect and remit occupancy/transient-occupancy tax in many but not all jurisdictions, leaving hosts responsible for tracking which jurisdictions require self-remittance; California's SB 346, effective January 1, 2026, gives cities a new compulsory mechanism to obtain host operating data directly from short-term-rental platforms for enforcement purposes, and IRS audit rates for California short-term-rental hosts reportedly increased 23% in 2024-2025, driven mainly by 1099-K mismatches and missing deduction documentation.

• Existing short-term-rental compliance software (Neumo, Granicus/Host Compliance, OpenGov, Localgov) is built and sold exclusively to municipal governments for monitoring and auditing hosts; existing host-facing tools (DeductFlow, Baselane) are proactive expense-tracking and tax-filing apps, not audit-response tools. No self-serve product for assembling and formatting a response to an actual occupancy-tax audit notice was found.

When to bring in a professional

Self-serve responses fit routine cases: clear facts, amounts a business can absorb, and a deadline still ahead of you. Bring in a licensed professional when the amount at stake is large relative to their fee, the facts are genuinely disputed, criminal exposure is possible, or the deadline has already passed. A short paid consultation to sanity-check your plan is often worth it even when you handle the filing yourself.
