03OK. But are there deductions most roofers don't even know they're missing?

What Most Roofers Miss

The retirement account most roofers skip
A SEP-IRA lets you put away up to 25% of what you earn (up to $72,000). If you made $120K this year, that's potentially $21,000 off your taxable income before you even file. At a typical combined rate, that's about $5,900 you keep instead of sending to the IRS. Almost no general tax preparer brings this up. We always do.
Picking the wrong vehicle deduction method
If your truck is heavy-duty (over 6,000 lbs), the actual expense method almost always beats the standard mileage rate, especially in the year you buy a new vehicle. A $65,000 crew cab truck can generate $15,000 to $30,000 in deductions in year one using actual expense, compared to maybe $8,400 from mileage alone. Choosing the wrong method could cost you thousands without you ever knowing.
Health insurance deducted in the wrong place
Self-employed health insurance belongs on your 1040 directly, not on Schedule C. When it ends up in the wrong place, it still lowers your income tax, but you miss the SE tax savings. On $700/month in premiums, that placement error costs you about $1,200/year. It's a simple fix that most general preparers never catch.
04OK so I know what to deduct. But when do I actually have to pay, and how do I avoid getting hit with a penalty?

Quarterly Estimated Tax for Roofers

When you work for yourself, the IRS doesn't wait until April to get paid. You're expected to pay taxes four times a year as you earn. Miss one of those payments and you'll get hit with an underpayment penalty, usually 4–7% on whatever you shorted them. The easy way to avoid this: pay at least what you owed last year, split into four payments. That's called the safe harbor rule, and following it means no penalty no matter what you end up owing in April.

Income PeriodPayment DueQuarter
Q1: Jan 1 to Mar 31April 15, 2026Full quarter
Q2: Apr 1 to May 31June 15, 2026Short quarter
Q3: Jun 1 to Aug 31September 15, 2026Full quarter
Q4: Sep 1 to Dec 31January 15, 2027Full quarter
Quick estimate formula: Take your expected annual net profit × 25.3% (15.3% SE tax + estimated 10% income tax for most brackets). Divide by 4 for your quarterly payment. Example: $120K net profit × 25.3% = $30,360/year, divided by 4 = $7,590/quarter. Your actual rate depends on deductions and filing status.
05So I know what I owe and when. Is there a way to actually keep more of what I earn?

Earning $75K+ Net? There's a Strategy Worth Knowing.

Once your roofing business is clearing $75,000 or more in net profit, there's a legal structure change that can put a significant chunk of money back in your pocket. It's called an S-Corp election, and it works by changing how your income is classified, reducing the portion subject to self-employment tax. Here's what the difference looks like on $100K:

LLC (no S-Corp)
$14,130
SE tax on $100K net
With S-Corp Election
~$5,650
Payroll tax on $60K salary

06That covers the big stuff. But what about all the other questions roofers always ask?
