B&H files tax extensions for Willow Glen individuals and businesses — Form 4868 extends your personal return deadline to October 15, 2027. But remember: an extension extends time to file, not time to pay. Taxes owed are still due April 15.
Filing a tax extension is simple — but making the right estimated payment with it is critical. A missed or underpaid estimate means penalty and interest even if your extension was filed on time. We file and calculate correctly.
The IRS late-filing penalty is 5% of taxes owed per month — up to 25%. A properly filed Form 4868 by April 15 eliminates this penalty entirely, giving you until October 15 to file without penalty exposure.
Waiting on a K-1, late 1099, or partnership document? An extension is the right move. We file immediately and complete your return once all documents are in hand — no rushing, no errors from incomplete information.
Filing late without an extension triggers both the late-filing penalty (5%/month) AND the late-payment penalty (0.5%/month). Filing an extension eliminates the larger penalty — but taxes owed must still be paid by April 15.
We calculate how much you likely owe and help you send the right estimated payment with your extension. Paying too little triggers the late-payment penalty — paying the right amount avoids it entirely, even with an October filing.
We prepare and e-file Form 4868 for Willow Glen individuals, extending your 1040 filing deadline from April 15 to October 15, 2027. We estimate your balance due and advise on the payment to send with the extension.
We file Form 7004 for Willow Glen LLCs, S-corps, and partnerships — extending S-corp/partnership deadlines to September 15 and C-corp deadlines to October 15, 2027.
The most important part of any extension: we estimate your tax liability and calculate the right payment to send with the extension, minimizing the 0.5%/month late-payment penalty.
Many Willow Glen clients request an extension because their books aren't ready. We do catch-up accounting to get QuickBooks current so your actual return can be completed accurately before October.
We don't just file the extension and disappear. We complete and file your full return — individual or business — before the extended October 15 deadline with all documents in hand.
Filed an extension but never completed the return? We prepare delinquent returns for prior years and help you understand your penalty and interest situation with the IRS and FTB.
Yes — a timely filed Form 4868 by April 15 eliminates the 5%-per-month late-filing penalty. However, it does NOT eliminate the 0.5%-per-month late-payment penalty on any tax owed after April 15. You must estimate and pay your balance due by April 15 to avoid the payment penalty, even if you file later.
If you file Form 4868 by April 15, 2027, your individual return deadline is extended to October 15, 2027. California also grants an automatic six-month extension when you pay your estimated tax balance by April 15. There is no further extension beyond October 15.
Businesses file Form 7004 for a six-month extension. S-corps and partnerships (March 15 original deadline) are extended to September 15, 2027. C-corps (April 15 original deadline) are extended to October 15, 2027. We file Form 7004 and calculate any estimated payment due with the extension.
Yes. An extension extends time to file your return — not time to pay your taxes. Any balance owed is still due April 15, 2027 to avoid the 0.5%-per-month late-payment penalty plus interest. We estimate your tax liability and help you make the right payment with your extension.
Once your extension window opens, we complete your full return — individual or business. B&H handles federal and California tax preparation for Willow Glen sole proprietors, LLCs, and S-corps.
