Your S corporation return, prepared by the team that can also keep the books behind it. Base price $1,200 for the federal Form 1120-S with shareholder K-1s, published up front. S corporations in California and every other state — handled online.
The federal S corporation return, including the balance sheet (Schedule L), the book-to-tax reconciliation (Schedule M-1) and the equity roll-forward (Schedule M-2) where required.
Each owner’s share of income, deductions, credits and distributions, delivered in time to file their personal return.
The IRS requires shareholder-employees to be paid reasonable wages before taking distributions. We review what was paid against what the business did, and flag gaps before the return is filed.
Basis determines whether distributions are tax-free and whether losses can be deducted. We track it each year so your personal Form 7203 is supportable.
Prepared alongside the federal return for the state where the corporation is registered — California Form 100S, or the equivalent elsewhere — and quoted with it.
If the books aren’t ready by March, we file Form 7004 for the automatic six-month extension so the return is right rather than rushed.
Calendar-year Form 1120-S is due on the 15th day of the third month after year end. Tax-year 2025 returns were due March 16, 2026; tax-year 2026 returns are due March 15, 2027. Full deadline and extension guide →
Form 7004 extends the filing deadline, not the K-1 timing your shareholders are waiting on for their own returns — so we plan the books around it.
For returns due after December 31, 2025 the penalty is $255 per shareholder for each month or part of a month the return is late, up to 12 months — even when no tax is due. A two-owner S corp that files six months late owes $3,060 before interest.
Failing to furnish a correct K-1 to a shareholder on time carries its own penalty per statement, separate from the late-return penalty.
California S corporations pay 1.5% of net income with an $800 minimum franchise tax (waived for the first year of a new corporation) on Form 100S, due the same day as the federal return.
We confirm the entity, the state, the number of shareholders and the state of the books, then confirm the price from the $1,200 base before any work begins.
An 1120-S is prepared from a reconciled balance sheet, not a bank download. If the books are behind, catch-up bookkeeping comes first and is quoted separately.
Year-end financials, payroll reports, prior-year return, shareholder details and the items on our checklist below, uploaded to your secure portal.
Officer pay, distributions, basis, depreciation and state adjustments are worked through, with questions batched rather than sent one at a time.
You see the return and each K-1 before anything is filed, with the changes from last year explained.
Federal and state returns e-filed, acceptance confirmed, and K-1s delivered to each shareholder.
Profit & loss and balance sheet for the year, reconciled to the bank and credit card statements.
Officer and employee wages for the year, including W-2s and Forms 941/940 or your payroll provider’s annual summary.
Last year’s return carries forward basis, depreciation and any suspended items.
Names, addresses, ownership percentages and any changes in ownership during the year, plus distributions paid to each owner.
Fixed assets bought or sold, loan statements, and shareholder health insurance premiums (which belong on the W-2).
Where the corporation is registered, where it has employees or property, and any state estimated payments already made.
The S corporation return prepared and filed, with owner K-1s. Base pricing is published on the pricing page so you know where you stand before we begin.
Additional states, a large number of shareholders, unreconciled books, fixed-asset schedules that need rebuilding, or a mid-year ownership change. We confirm the full scope and price before work begins — not after.
Your K-1 flows to your personal return. Personal tax preparation starts at $300 and is quoted alongside the business return when we prepare both.
Clients on a monthly bookkeeping plan arrive at tax season with a reconciled balance sheet already done, which is what keeps an S corp return at the base price.

Yes, but the books come first. We scope catch-up bookkeeping separately, then prepare the 1120-S from the reconciled result.
