One flat monthly price covers your service with no hourly billing or surprise invoices. You always know what you pay, making it easy to budget for professional accounting help.
When you call or email, Bill or Hannah responds, not a call center or account manager. You get the same accountant every month who knows your San Francisco business inside and out.
San Francisco has its own minimum wage: $18.67/hr effective July 1, 2026, indexed to the Bay Area CPI. SF also has a Gross Receipts Business Tax that applies to businesses with San Francisco operations. We apply the current San Francisco rate automatically across our payroll and bookkeeping services before each effective date.
We serve San Francisco businesses alongside clients from Milpitas to Fremont, knowing the California tax rules, CDTFA filing requirements, and EDD payroll compliance that affect your business.
We file your federal Form 4868 by the April 15 deadline, extending your federal individual return to October 15, 2027. This eliminates the 5 percent per month failure-to-file penalty while you gather documents.
California grants an automatic 6-month extension to October 15 if you pay 90% of your tax liability by April 15. We calculate your payment amount and file FTB 3519 correctly so the extension is valid.
S-corp and partnership returns due March 15 can be extended to September 15 using Form 7004. We file business extensions on time and track new deadlines for every San Francisco business entity we serve.
An extension to file is NOT an extension to pay. We calculate your estimated 2026 tax liability, determine how much you owe by April 15, and ensure you pay enough to avoid underpayment penalties.
After your extension is filed, we work to complete your actual return as quickly as possible, gathering documents, preparing the return, and filing well before the October 15 deadline.
Filed an extension last year but never finished the return? We prepare overdue returns promptly, calculate IRS and FTB penalties, and file to stop the penalty clock, often reducing the total amount owed.
Yes. B&H files federal Form 4868 and Form 7004 extensions by the April 15 and March 15 deadlines for San Francisco clients. We calculate your required extension payment to avoid underpayment penalties. Call 408-256-0339.
Filing Form 4868 by April 15 eliminates the failure-to-file penalty, but it does NOT extend your time to pay. If you owe tax, you must pay 90% of your 2026 liability by April 15 to avoid the IRS underpayment penalty. We calculate the correct amount for every San Francisco client.
S-corp and partnership returns are originally due March 15, 2027. Form 7004 extends them to September 15, 2027. Individual returns are originally due April 15, 2027 and Form 4868 extends to October 15, 2027. We track all deadlines for San Francisco clients.
Call us at 408-256-0339 immediately. If you missed the original deadline without filing an extension, the IRS failure-to-file penalty is now accruing at 5% per month. We file the return as quickly as possible to stop the penalty clock and can in some cases request IRS penalty abatement for first-time filers.
