When are business tax returns due?

Partnership and S corporation returns are due March 15, and C corporation returns are generally due April 15, both with a six-month extension available. We track these dates for you and confirm extension filings in writing so there is no ambiguity about status.

What happens if we file late?

Partnerships and S corporations face a penalty calculated per partner or shareholder for each month the return is late, which adds up quickly even for a small entity. If this is a first occurrence and your recent filing history is otherwise clean, we can often request a penalty abatement on your behalf.

Do you prepare K-1s for our partners or shareholders?

Yes, K-1 preparation and distribution are included with every partnership and S corporation return we prepare. We deliver them to you in time for your partners or shareholders to use in their own individual filings.

Can you prepare returns from messy or incomplete books?

Yes, though we reconcile the books first so the return is accurate, and we will flag any cleanup work needed before we finalize numbers. This upfront step protects you from filing a return that has to be amended later.

What sends contractors looking for this

Our books are not ready when it is time to file

A return is only as accurate as the bookkeeping behind it, and a lot of shops arrive at filing season with a bank feed full of miscategorized transactions, a loan balance that doesn't match the actual note on the new service van, and a depreciation schedule that was never updated for last December's equipment purchase.

Sorting that out while trying to prepare the return takes real time, and it usually means the return finishes later than planned or lands on an extension the owner wasn't expecting.

A rushed cleanup under deadline pressure raises the odds of an error on the filed return, and an extension that isn't clearly communicated can leave an owner thinking a return was filed when it wasn't, which by itself can trigger a failure-to-file penalty on top of whatever tax is owed.

We are worried we are missing deductions on our vehicles and equipment

General bookkeeping software will not tell you that the new service van bought in December can often be written off in full the same year under Section 179 or bonus depreciation, both rules that let you deduct the full cost of qualifying equipment right away instead of spreading it over five or more years. It also won't flag fuel and mileage on a full fleet, tool purchases, or the qualified business income deduction, which lets many owners deduct a slice of their business profit before it's even taxed.

Preparers moving quickly through filing season can miss these too, especially on a return that otherwise looks routine, and owners rarely know enough to ask about a deduction they've never heard of.

A missed deduction doesn't just cost money the year it's missed. Fixing it later requires an amended return, and the window to claim a refund closes three years from the original filing deadline, so a Section 179 write-off missed on a 60,000 dollar van can mean thousands of dollars in tax savings gone for good.

We filed late last year and got hit with a penalty

S corporation returns are due March 15, a month earlier than the individual deadline most owners are used to, and it's an easy date to miss when you're also juggling the busy start of spring service calls. Missing it by even a day triggers a penalty calculated per shareholder, per month late.

Once that penalty posts, removing it generally takes a written request showing reasonable cause, or for a first-time miss, a request for first-time penalty abatement, which is a one-time waiver the IRS grants to a business with a clean recent filing history.

For a two-owner S corp filed two months late, the penalty alone runs about 900 dollars before any tax is even considered, and a shop that lets it happen more than once will find the IRS far less willing to waive it the next time.

How we fix each of those

01
Books reconciled against your job costing before preparation starts
We reconcile bank, loan, and credit card accounts and update the depreciation schedule for every van and piece of equipment bought during the year before we touch the return, so the return is built on numbers that are already right instead of numbers we're fixing while the clock runs.
02
A deduction review built around vans, tools, and fleet costs
Every year we run your equipment purchases, fuel and mileage log, and profit through a checklist covering Section 179, bonus depreciation, and the qualified business income deduction, so a van bought in December gets the write-off it qualifies for instead of getting missed on a return that looked routine.
03
Deadline tracking that starts well before March 15
We set internal cutoffs weeks ahead of the S corporation deadline so open items get resolved before the due date, and we file an extension proactively whenever information won't be ready in time, so a busy spring service season never turns into a missed filing.

Brett Neal has been our family's accountant for over six years now, because he is the most dependable professional in this business. We started with Brett as two separate single-filers with simple W-2's and quickly graduated to a married couple having multiple types of complicated business/tax filings. Brett took every shift in stride; every transition has been carried out smoothly and without any hiccups. Trust that this is the guy for all your filing, bookkeeping, and financial consulting needs.
