San Diego Tax Help: IRS & FTB Back Taxes, Levies, Audits (2026)
Updated: 21 hours ago
Tax help in San Diego: who this guide is for
If you live or run a business in San Diego and the IRS or the FTB has started writing to you, this page explains what actually happens next, where the local offices are and what they can and cannot do, and how cases from San Diego County get resolved without anyone taking a day off to sit in a federal building.
I am an Enrolled Agent, federally licensed to represent taxpayers before the IRS, and my firm handles back taxes, levies, audits and unfiled returns for clients across San Diego and its suburbs, including Chula Vista, Oceanside, Escondido, Carlsbad, El Cajon and National City. Everything here is general information, not individual advice; the last section explains how to get a free review of your own notices.
Your IRS office in San Diego, and what it can actually do
The IRS Taxpayer Assistance Center serving San Diego is the San Diego Taxpayer Assistance Center, at 880 Front St., Suite 1247, San Diego, CA 92101. By appointment only through the national IRS line, 844-545-5640. The IRS office locator lists Monday through Friday, 8:30am to 4:30pm, and posts partial-day closures by date, so check it before driving in. Other offices in the area include San Marcos Taxpayer Assistance Center, 1 Civic Center Dr., San Marcos, CA 92069, for North County including Escondido, Oceanside and Carlsbad.
It helps to know what a Taxpayer Assistance Center is for. It can verify your identity, take a payment, give you transcripts and answer account questions. It does not negotiate: nobody at the counter can settle a balance, release a levy on their own authority or decide an audit. Those decisions sit with collection, examination and appeals units that work by mail, phone and fax, which is why most representation happens without a visit to the office at all.
The Taxpayer Advocate Service is different. It is an independent office inside the IRS that steps in when normal channels have stalled or a levy is causing hardship. The local office for San Diego: Taxpayer Advocate Service, San Diego Office, 701 B Street, Suite 902, San Diego, CA 92101, (619) 744-7156. It is a genuine safety valve, but it is not a shortcut around filing the missing returns or answering the notice in front of you.
The California side: Franchise Tax Board
The FTB administers California income tax and sends most state notices San Diego residents receive, including residency questions for military families and people who moved away. The California Department of Tax and Fee Administration handles sales and use tax from 15015 Avenue of Science, Suite 200 (1-800-400-7115 statewide), and the Employment Development Department handles payroll tax from an employment tax office at 10636 Scripps Summit Court, Suite 202 (1-888-745-3886).
Franchise Tax Board local office: 7575 Metropolitan Drive, Suite 201, San Diego, CA 92108-4532 (Mission Valley); appointments at 619-688-2550 or through the FTB's online scheduling link; check, money order and credit card accepted, no cash.
Federal and state collection are separate tracks: an IRS installment agreement does nothing to stop a California garnishment, and a state payment plan does not pause the IRS. Every San Diego case we take is mapped across both agencies before anything is negotiated. Our California state page covers the state side in detail.
San Diego taxes people forget about
Beyond the IRS and the FTB, San Diego has local obligations that show up as surprise bills, usually when a business or a rental has been running for a few years without them:
City of San Diego Business Tax Certificate and Rental Unit Business Tax: all businesses operating in the city must obtain a Business Tax Certificate, including home-based businesses, self-employed persons and independent contractors, and the Rental Unit Business Tax is imposed annually on anyone who owns, operates or manages residential rental real estate in the city; questions go to 619-615-1500.
City of San Diego Transient Occupancy Tax: any property rented to occupants for less than one month needs a Transient Occupancy Registration Certificate; the operator collects the tax with the rent, holds it in trust and remits monthly by the last day of the following month, and short-term residential occupancy hosts must include the certificate number on all advertisements. Since May 2025 the rate depends on which of three tax zones the property is in.
San Diego County unsecured property tax: the Treasurer-Tax Collector bills boats, aircraft, business fixtures and business personal property separately from real estate; most bills are due August 31 and a penalty applies once delinquent.
San Diego County Business Property Statement: the Assessor mails it in January with an April 1 due date, adds a penalty to statements filed after May 7, closes e-filing on May 31, and provides Form 571-L only on request from the Business Division at (858) 505-6100.
The San Diego tax problems we see most
Every metro has its own pattern of tax trouble, because it has its own mix of work. In San Diego the cases that reach us most often look like this:
Active-duty Navy and Marine Corps families at Naval Base San Diego, Miramar and Camp Pendleton: The FTB says a servicemember arriving on permanent change of station orders does not become a resident and that military pay is not California-source income, while a California-domiciled member stationed elsewhere becomes a nonresident. A working spouse with California wages or a combat zone extension turns that into an FTB letter that needs a residency answer, not a payment.
Military retirees and veterans starting second careers or consulting on 1099s: The FTB says military retirement pay is taxable by California when received by a resident, and the IRS notes that disability payments may qualify for exclusions that pension income does not. Retirees who add consulting or a small business often under-withhold on the pension and skip estimated payments.
Cross-border commuters and families with accounts or businesses in Tijuana and Baja California: The IRS taxes U.S. citizens and resident aliens on worldwide income wherever they live, and anyone with a financial interest in or signature authority over foreign accounts above the reporting threshold must file an FBAR with FinCEN, separate from the return, with Form 8938 possibly required as well. Missed FBARs carry civil and potentially criminal penalties.
Short-term rental hosts in Mission Beach, Pacific Beach and the coastal neighborhoods: The city requires a Transient Occupancy Registration Certificate, monthly remittance and the certificate number on every listing, on top of reporting the rental income to the IRS and the FTB. Hosts who let a platform handle everything are often surprised by a city delinquency notice.
Biotech, defense and tech contractors on 1099s, plus rideshare and delivery drivers: The IRS Gig Economy Tax Center says income must be reported even when no Form 1099 arrives, and contract pay carries no withholding for income or self-employment tax. A year or two of missed estimated payments becomes a balance the IRS collects through notices and eventually levies.
Three things to know about San Diego cases
Military residency drives many San Diego FTB cases: servicemembers domiciled elsewhere stay nonresidents while stationed here on PCS orders, military pay is not California-source, and California-domiciled members stationed outside the state become nonresidents, so one household can hold two residency statuses.
The border makes foreign account reporting routine: U.S. persons with Mexican accounts above the threshold file the FBAR electronically with FinCEN rather than with the return, and the IRS grants an automatic extension to October 15 for those who miss April 15.
The IRS center on Front Street, the Taxpayer Advocate Service on B Street and the FTB office in Mission Valley are three different buildings, and the San Marcos center covers North County so Escondido, Oceanside and Carlsbad residents need not drive downtown.
How we work with San Diego clients
The process is the same whether you are in Chula Vista, Oceanside and Escondido or overseas. You sign IRS Form 2848, which lets us speak to the IRS for you and pulls the notices to our office instead of your mailbox; for state matters we file the state's own power-of-attorney form. We then pull your IRS account and wage transcripts and the state account history, so the first conversation is about real numbers rather than guesses.
From there the order is almost always the same: stop any active levy or garnishment, file whatever returns are missing (a return the IRS prepared for you is usually far higher than the real liability), and only then negotiate the balance through a payment plan, an offer in compromise, penalty relief or currently-not-collectible status, depending on what the financials support. Meetings are by phone or video, documents move through a secure upload link, and signatures are electronic. You never need to visit an office, and neither the IRS nor the FTB requires an in-person meeting for the vast majority of cases.
Frequently Asked Questions
Do I have to go to the IRS office on Front Street downtown?
No. The Taxpayer Assistance Center at 880 Front St. works by appointment through 844-545-5640 and handles in-person tasks such as identity verification and payments, with a second center in San Marcos for North County. Notices, levies, audits and payment arrangements are handled by phone, mail and online, and an authorized representative can do that work for you.
I am stationed in San Diego but my home state is Texas. Why did the FTB send me a letter?
The FTB says a servicemember who came on permanent change of station orders does not become a resident and that military pay is not California-source income, but it may still ask for a return when it sees California wages, rental income or a spouse's earnings. The answer is usually a nonresident return or a residency explanation rather than the tax the letter proposes.
I have a bank account in Tijuana. Do I need to report it to the IRS?
If the combined value of your foreign accounts passed the reporting threshold at any time during the year, the IRS says you must file an FBAR through FinCEN's BSA E-Filing System, separately from your tax return, and worldwide income including Mexican interest must be reported. Past-due FBARs have their own correction procedures, so review the history before filing anything.
Can you handle the FTB and the IRS at the same time?
Yes. The IRS is authorized through Form 2848, and the FTB accepts its own Power of Attorney Declaration, Form FTB 3520, which allows a representative to talk to the FTB, receive account information and represent you. Residency cases in particular are handled with both agencies in view.
Do you meet clients in person in San Diego?
No office visit is needed. All State Tax Resolution works by phone, video and secure document upload, and we file IRS Form 2848 so an Enrolled Agent is authorized to speak with the IRS on your behalf. That suits deployed servicemembers and cross-border commuters as well as anyone else in San Diego County.
