The 15 March deadline is not missed
Partnership and S-corp penalties are charged per owner, per month, even when no tax is owed.
Business Tax
K-1s flow straight through to the owners without a hand-off — which removes the single most common source of filing errors in small business.
A business return is only as good as the books behind it. Before we prepare anything we reconcile the year, confirm that owner compensation and distributions are recorded defensibly, and sweep for deductions and credits that were missed while the year was running.
Then we file the entity return and the personal returns together, so nothing is lost between the two. If your books are behind, we quote the clean-up separately and fix it first — filing on top of unreconciled records is how errors become permanent.

FAQ
Yes, but we clean them up first and quote that separately as a fixed-fee project. Filing on top of unreconciled records produces a return nobody can defend, and it usually costs more in the long run than fixing the books once.
Partnerships and S-corporations are due 15 March; C-corporations and single-member LLCs reporting on Schedule C are due 15 April. Extensions move the filing date but never the payment date — tax owed is still due on the original deadline.
We handle the planning that comes with compliance — entity elections, reasonable compensation, depreciation choices and estimated payments. Advanced strategy work such as cost segregation, retirement plan design or wealth structuring is handled by our sister practice, Herbert Financial Group, and we refer you across when that is what the situation calls for.
