Tax Extension — Mountain View, CA

Tax Extension Filing in Mountain View, CA

Need more time to file your taxes? B&H files federal and California tax extensions for Mountain View businesses and individuals — fast, accurate, and with proper estimated payment calculation so you avoid penalties.

Extension Filing Done Right for Mountain View

A tax extension gives you more time to file — not more time to pay. Many Mountain View business owners file extensions without estimating what they owe and end up with penalty and interest charges. We calculate your liability before filing so you're protected.

Same-Day Extension Filing

Deadline approaching? We can file your federal Form 4868 or California FTB Form 3519/3539 the same day you call. Most extensions are processed electronically within minutes of submission.

Estimated Payment Calculation

We estimate your tax liability before filing the extension so you pay the right amount by April 15 — eliminating failure-to-pay penalties and daily interest charges that accrue on any unpaid balance.

Both Federal and California

A federal extension does not automatically extend your California return. We file both simultaneously — IRS Form 4868 (or 7004 for businesses) and the applicable FTB form — in a single engagement.

Path to a Complete Return

We don't just file an extension and disappear. Most Mountain View clients who extend with us complete their full return with B&H before the extended deadline — no need to find a new preparer.

Individual Extension (Form 4868)

Extends your federal 1040 deadline from April 15 to October 15. We calculate your estimated tax liability and file the extension with the correct payment amount — same day when needed.

Business Extension (Form 7004)

Extends S-corps and partnerships to September 15; C-corps to October 15. We file IRS Form 7004 electronically and handle the California FTB business extension simultaneously.

California FTB Extension

California Form 3519 (individual) or 3539 (business entity) filed by the original deadline. We calculate your California estimated tax payment to avoid FTB late-payment penalties.

Estimated Tax Payment Calculation

We review your prior year return and current year income to estimate what you owe — so you pay the right amount with the extension and avoid the 5% monthly failure-to-pay penalty.

Full Return After Extension

Extension filed — now what? We prepare your complete federal and California returns before the extended deadline, incorporating any missing documents that made the original deadline impossible.

Multi-Year Extension Cleanup

Behind on multiple years? We file current-year extensions while preparing prior years in order — a common situation for Mountain View startups that outpaced their accounting infrastructure.

Mountain View Tax Extension FAQ

How do I file a tax extension in Mountain View CA?

File IRS Form 4868 (individuals) or Form 7004 (businesses) by the April 15 deadline for federal, and the applicable FTB form for California. B&H files both electronically — call 408-256-0339 and we can handle it the same day.

Does a tax extension mean I don't have to pay by April 15?

No. An extension extends the filing deadline only. Any estimated tax owed must still be paid by the original deadline (April 15 for individuals, March 15 for S-corps and partnerships). We calculate your estimated liability before filing the extension so you pay the right amount.

What are the extended deadlines for Mountain View businesses?

S-corps and partnerships: original March 15, extended to September 15. C-corps: original April 15, extended to October 15. Individual 1040: original April 15, extended to October 15. California mirrors federal dates.

Can B&H file an extension for my Mountain View startup?

Yes. We file extensions for S-corps, LLCs, partnerships, C-corps, and individuals — same day when needed. Call 408-256-0339 as soon as you know you need more time and we'll handle both the federal and California filings immediately.
