Every March, an HVAC owner calls us on the 14th asking if there’s still time to file the S-corp election.
There is, barely, and then payroll has to be running before the next check is cut.
It works, but it’s the hard way.
The easy way is to file Form 2553 in September, while the summer cash is still in the account and the phones have quieted down.
The IRS gives you a whole year to file for the next January 1, and September is the month an HVAC business has the time and the numbers to do it right.
So let’s walk through why the timing matters, what actually changes when your HVAC business becomes an S-corp, and what to get done this fall.
You can file Form 2553 in September and have the election take effect on January 1 of next year, because the IRS accepts the form at any time during the tax year before the one it applies to.
The Form 2553 instructions put it this way: file “no more than 2 months and 15 days after the beginning of the tax year the election is to take effect, or at any time during the tax year preceding the tax year it is to take effect.”
Most owners only know the first half of that sentence, the March 15 deadline for a calendar-year business, and it’s the one that produces the panicked calls. The second half is the one we’d rather you use.
File in September, and your election is on file three months early, with time for the IRS acceptance letter to arrive before the first payroll run.
If you’ve been thinking about the S-corp election for HVAC business owners since your CPA mentioned it at tax time, this is the window that turns “someday” into a date.
For an HVAC shop specifically, September has a second advantage that has nothing to do with the IRS, and we’ll look at that next.
September works better than March because it’s the first slow month after the busiest stretch of your year, so you have both the cash and the time to set the election up properly.
We wrote about the HVAC cash flow cycle earlier this year: the cooling season runs May through August, heating picks up in November, and September and October are the thin months in between.
In March, you’re heading into spring tune-ups with a tax return due and a bank balance that’s been carrying you since the fall. In September, the summer invoices have cleared and you can actually sit down with the trailing 12 months of numbers.
Let’s look at an example. An owner runs two crews out of Fort Worth and does most of the year’s revenue between May and August. In September, the books show a full summer of real profit, not a projection. That’s the month to decide what a reasonable salary looks like, set up payroll so it’s tested before January, and build the slow-season budget at the same time. Try that in March and you’re doing it between install calls.
The catch is that seasonal income is exactly the thing that makes some HVAC owners hesitate on the election in the first place. That’s the next question.
Seasonal income means you should judge the S-corp decision on a full trailing year, not on your slowest month, and September is when you have that full year in front of you.
We’ve said before that inconsistent income is one of the reasons not to elect S-corp status, and that still holds. Payroll, quarterly filings, and a separate corporate return don’t take the winter off.
The question isn’t whether October looks thin. Every HVAC October looks thin. The question is whether the business clears the profit level where the election pays for itself, year after year.
We’ve written about where that threshold sits for most small businesses, and an HVAC shop with two or more crews is usually well past it once you look at the whole year.
Where seasonal income does change the plan is in how you pay yourself. A salary that’s easy to cover in July might be hard to cover in October, which is one more reason to set it in September with a slow-season budget next to it. That’s the practical side.
The question then becomes what the election actually changes on your tax return.
The S-corp election changes how your profit is taxed for Social Security and Medicare, not how much profit you make.
As a sole proprietor or a single-member LLC, all of your net business earnings are subject to self-employment tax, which the IRS describes as 12.4% for Social Security and 2.9% for Medicare. The Social Security piece stops at an annual cap that changes each year. The Medicare piece doesn’t stop.
After the election, you become an employee of your own company. You pay yourself a wage, which carries payroll tax, and you can take the rest of the profit as a distribution, which doesn’t.
Whether that split leaves you better off depends on your profit, your salary, and the cost of payroll and a corporate return, so run your own numbers through our S-corp tax calculator first. Depending on your situation, the answer can be yes, not yet, or not worth it.
One Texas note, since we get asked: there’s no state income tax here, so the election is a federal question. The Texas franchise tax is a separate question, and the S-corp election doesn’t change whether it applies to you.
The wage and distribution split is where the whole thing lives, and it’s also where the IRS pays the most attention, which brings us to the part most owners get wrong.
Before you take a single distribution, the IRS expects your S-corp to pay you a reasonable wage for the work you actually do.
In the IRS’s own words, S corporations “must pay reasonable compensation to a shareholder-employee in return for services that the employee provides to the corporation before non-wage distributions may be made,” and it has the authority to reclassify distributions as wages if the salary doesn’t hold up.
For an HVAC owner, “the work you actually do” is the whole question. If you’re still on the tools four days a week and running dispatch at night, your reasonable salary looks different from an owner with a service manager who spends the week on bids and hiring.
What you’d pay someone else to do your job is the starting point, and we’ve written a longer piece on how to set an S-corp salary you can defend.
This is the decision that benefits most from a September start. You have real numbers from the busy season, you know what your lead tech and office manager cost, and you have time to land on a salary that’s reasonable, affordable in the slow months, and documented.
Salary is the biggest item on the fall checklist, but not the only one.
The election works smoothly when payroll, bookkeeping, and the form itself are handled before January 1, and September gives you the runway for each one. Working backward from the effective date:
Get payroll set up and test-run it. You’ll need a payroll provider, state unemployment registration, and a first pay date on the calendar. Our Fort Worth payroll team can set this up for you in the fall.
Clean up the books. An S-corp files its own return, and the cleaner the trailing year, the easier that first return is. If the QuickBooks file has a “Misc” category doing a lot of heavy lifting, fix it now.
Build the slow-season budget alongside the salary. Your wage has to clear in February, not just July.
File the form. Every shareholder has to sign, and if you’re married in Texas, the IRS instructions note that a spouse with a community interest in the stock consents too. An LLC doesn’t need a separate Form 8832 to get there. We walk through every line in our guide to filing an S-corp election on Form 2553, so we won’t repeat the form here.
Keep the IRS acceptance letter. It’s the proof your election is in effect, and you’ll want it the first time a bank or a bonding company asks.
Do that in the fall and the election starts on January 1 without drama. But what if this post found you after the window closed? That’s the last question.
If you wanted the election for this year and missed the March deadline, the IRS has a late election relief process, but it’s a repair, not a plan.
Under Rev. Proc. 2013-30, relief is available if you meant to be an S-corp, you have reasonable cause for filing late, you and every shareholder reported income as if the election were in effect, and less than three years and 75 days have passed since the effective date you wanted.
That’s a real option, and it exists because plenty of owners find out too late that nobody filed the form. Filing in September for next January means never having to explain reasonable cause to anyone.
If you want to know whether your HVAC business clears the bar, our HVAC accounting team in Fort Worth can look at your trailing year with you and tell you straight.
Reach out through our get in touch page, and we’ll get it on the calendar this month, while the phones are quiet.
See you in the slow season.
