Need more time to file your 2026 tax return? B&H files Form 4868 (individual) or Form 7004 (business) for Sunnyvale taxpayers, estimates the balance due to avoid penalties, and completes your full return before the extended deadline.
A tax extension buys time to file — but taxes owed are still due on the original deadline. Many Sunnyvale taxpayers file extensions without paying the balance due, then face interest and penalties. B&H estimates and pays the correct amount so your extension actually protects you.
We calculate your estimated tax liability before filing the extension, so you pay enough to avoid IRS and FTB interest. Filing an extension without paying often costs more than filing late without an extension.
We file your federal extension (Form 4868 or 7004) and California FTB extension simultaneously, so both deadlines are protected. California does not require a separate form if you have a federal extension and no balance due.
We don't just file your extension and disappear. We complete and file your full return before the October 15 extended deadline, using the documents you provide after the original deadline passes.
We file extensions for Sunnyvale S-corps, partnerships, LLCs, C-corps, and sole proprietors — each with the correct form, payment amount, and extended deadline based on your entity type.
Extends your individual (Form 1040) filing deadline from April 15, 2027 to October 15, 2027. We estimate your balance due and submit payment with the extension to avoid interest and late-payment penalties.
Extends S-corps and partnerships (March 15 → September 15) and C-corps (April 15 → October 15). We file Form 7004 electronically and pay estimated balance due to prevent late-payment penalties.
California grants an automatic extension when a federal extension is filed — but balance due must still be paid by the original deadline. We calculate and pay your CA estimate alongside your federal extension.
After extension, we complete and file your full return before the extended deadline — October 15 for individuals and C-corps, September 15 for S-corps and partnerships.
Sunnyvale tech workers with ISO exercises, RSU vesting, or equity liquidity events often need extensions to finalize cost-basis calculations. We handle the complexity of stock-related tax items accurately.
A properly filed extension eliminates the 5%/month late-filing penalty on unpaid tax. Combined with correct payment estimates, B&H protects Sunnyvale clients from the most costly tax penalties.
The original individual deadline is April 15, 2027. A Form 4868 extension moves the filing deadline to October 15, 2027. Taxes owed are still due April 15 — B&H estimates the balance and pays it with the extension so you avoid interest and late-payment penalties.
No separate CA form is required if you have a federal extension and owe no California tax or are getting a refund. If you owe CA tax, you must pay by April 15, 2027 to avoid FTB interest and penalties. We calculate your California balance due and pay simultaneously with your federal extension.
S-corps and partnerships can extend from March 15 to September 15, 2027 using Form 7004. C-corps extend from April 15 to October 15. LLCs and sole proprietors use Form 4868 for an April 15 → October 15 extension. B&H files the correct form for your entity type.
Yes. We file the extension to protect you from late-filing penalties, pay the estimated balance due, then complete and file your full return before the extended deadline. This is especially common for Sunnyvale business owners and tech professionals managing complex equity or entity situations.
After your extension, we complete your full Sunnyvale business or individual return — S-corps, LLCs, 1040s with stock compensation, and California FTB filings. No handoff to a different preparer.
