Small business taxes aren't a once-a-year event — they're a year-round system with quarterly deadlines, structure-specific rules, and credits most owners never claim. For builders, remodelers, and contractors across Alamance and Caswell Counties, that system includes some North Carolina-specific layers worth understanding before you file.

Your Structure Determines Your Tax Map

Map your tax obligations before you gather a single document — the U.S. Small Business Administration confirms that your business structure and location determine which taxes you must pay and how, meaning there's no universal checklist that fits every small business.

For incorporated builders in Burlington, one obligation catches people off guard: the state franchise tax. The North Carolina Department of Revenue charges $1.50 per $1,000 of a corporation's tax base — completely separate from state income tax. If you've incorporated, plan for NC franchise tax alongside your income tax estimate. It's easy to underestimate if no one's explicitly flagging it.

Bottom line: If you've recently changed your entity structure — sole prop to LLC, or LLC to corporation — your obligations shifted with it.

Quarterly Payments: The Deadline Before the Deadline

One rule that trips up more self-employed owners than you'd expect: the IRS can penalize you for underpayment before you ever file. According to IRS Publication 334 (2025 Tax Guide for Small Business), owners who don't make sufficient estimated payments throughout the year may face a penalty on the unpaid amount — not just a lump sum at filing. Avoid the underpayment penalty by building quarterly installments into your cash flow planning from the start of the year.

In construction, project-based income rarely maps to even calendar quarters. A strong Q2 followed by a slow Q4 can leave your Q4 estimated payment underfunded if you're not adjusting actively.

Self-Employment Tax: The Full Rate

If you're running a sole proprietorship or single-member LLC, the self-employment tax is 15.3% — covering both the employer and employee share of Social Security and Medicare. Business owners coming from salaried work often remember 7.65% from their paystubs. That was only the employee half.

The upside: you can deduct half your SE tax when calculating your adjusted gross income, which softens the hit at year-end. Plan for the full 15.3% in your quarterly estimates; recover part of it when you file.

Getting Your Records Ready

Construction businesses generate a lot of paper: subcontractor invoices, material receipts, permit applications, and change orders accumulate fast. One practical approach is keeping a dedicated business credit card for all purchases — expenses sort automatically into categories, and you have a built-in backup record for IRS documentation without any extra tracking effort.

When you're working from scanned documents — archived permits, old contracts, signed forms — OCR tools can extract text directly without manual re-entry. Tax season often brings a stack of these to deal with, and this might help if you need to convert scanned PDFs into searchable, editable files before a deadline hits. Digitizing your records this way saves time and reduces errors when quarterly pressure is on.

Tax-Related Scams Are Targeting Small Businesses

Filing season is peak season for IRS impersonation scams — and the targets aren't random. The IRS warned during National Small Business Week 2024 that most cyberattacks are aimed at companies with fewer than 100 employees. Spot scams targeting small businesses by knowing the baseline: the IRS does not initiate contact via email, text, or social media. Any unexpected message claiming you owe a balance or that your return is under review should be verified at irs.gov directly — not through any link in the message.

Knowing that small businesses are the primary target, not large corporations, is the mindset shift that makes you harder to fool.

A Credit Most Builders Don't Claim

If you have employees and haven't yet set up a retirement plan, the startup cost may be smaller than expected — and partly recoverable. Eligible small employers can claim the retirement plan credit, up to $5,000 for the costs of establishing a SEP, SIMPLE IRA, or qualified retirement plan. It's one of the most consistently overlooked savings available to small business owners.

For ACBA member firms working to attract and retain skilled tradespeople in a competitive market, this credit is worth raising with your accountant before the deadline passes.

North Carolina's Layered Sales Tax

Builders and contractors who sell fixtures, materials, or custom components face a combined sales tax obligation: a 4.75% state base rate plus local county taxes of 2% to 2.5%, putting Burlington-area businesses at a combined 6.75% to 7.25%. Service-only contractors have limited exposure, but anyone moving product as part of a job should verify how North Carolina classifies their contracts under the sales tax code.

The classification isn't always obvious. A lump-sum construction contract is treated differently than a time-and-materials job, and getting it wrong can mean understated collections and a correction that's painful to address after the fact.

Pulling It Together Before the Deadline

The Alamance-Caswell Builders Association supports members year-round through networking, continuing education, and programs like NAHB Webinars and Shop Talks that regularly address business management topics. If you haven't engaged with the professional development side of ACBA membership lately, this is a good season to reconnect.

For personalized guidance, a CPA with construction industry experience — ideally one already familiar with Alamance and Caswell County's specific obligations — will help you match these strategies to your situation. Your ACBA membership network is a practical first stop for referrals.
