Chart of Accounts for Construction Company? Skip the 200-Line Nightmare (Austin Contractors Need THIS in 2025)
Why 92% of Austin Contractors FAIL at Job Costing (And How You’re Losing $1,200+/Job)
Picture this: A South Austin roofer completes a $50k shingle replacement, but miscategorizes their City of Austin Energy Green Building permit fee ($412) as “Materials” instead of “Job Expenses.” Result? They overpay $34 in sales tax (Austin’s 8.25% rate) and trigger a red flag for the Texas Comptroller. Multiply that by 20 jobs/year = $1,200+ in avoidable losses.
Austin’s hyper-local tax traps crush small contractors:
Utility Bonds: Misclassifying Austin Water’s $500 plumbing bond deposit as an “Expense” (instead of Asset #1810) → IRS disallows deductions + Travis County penalties.
Texas Materials Sourcing: Lumber from Austin Hardwoods (local vendor) qualifies for 0% sales tax under TX Tax Code §151.311 – but only if tracked in Account #5005.
Permit Costs: City of Austin Development Services fees (e.g., $325 for a $50k remodel) are NON-taxable. Categorize under #6890 – NOT “Materials.”
Hypothetical Win: An electrician in Pflugerville reclassified $8k in Williamson County utility deposits from “Equipment” to “Prepaid Assets.” Outcome: Potential $662 tax refund + avoided audit risk.

Forget bloated templates with “Union Dues” or “K-1 Allocations.” Here’s your Austin-optimized COA (works in QuickBooks Online):
| Account Type | Account # | Austin-Specific Example | Why It Matters |
|---|---|---|---|

| Materials | 5005 | Texas-Sourced Lumber (e.g., Austin Hardwoods) | 0% sales tax under TX law; audit-proof sourcing |
| Labor – Wages | 6200 | Hourly crew pay for Hyde Park remodel | Isolates direct labor costs for job profit tracking |
| Subcontractors | 6300 | Cedar Park drywall installer invoice #1234 | Tracks 1099 costs; separates from employee labor |
| Tools < $2.5k | 6450 | Nail guns for Round Rock fencing job | IRS Section 179 deduction eligibility under $2.5k |
| Prepaid Assets | 1810 | Austin Water Utility Bond deposit ($500) | Prevents sales tax errors; ensures proper asset treatment |
| Overhead – Local | 7005 | Austin Chamber membership dues | Deductible only if separated from job costs |
| Vehicle Fuel | 7450 | Gas for trucks at Mueller HEB station | Tracks TX-specific fuel tax credits |
| Materials – Taxable | 5010 | Lighting fixtures from non-TX supplier | Flags 8.25% sales tax owed on out-of-state purchases |
| Retainage Receivable | 1150 | 5% holdback on Travis County commercial job | Complies with TX Property Code §53.101 |
3 QuickBooks Setup Mistakes That Trigger Austin Tax Audits
Mistake #1: Using generic “Materials” instead of “Texas-Sourced Materials”
Austin Risk: Austin ISD school projects require ZERO sales tax on TX materials. Comingled accounts = $ penalties + failed audits.
Fix: Create Account #5005 exclusively for vendors like Austin Hardwoods or Georgetown Lumber.
Mistake #2: Calling Austin Water Utility Deposits “Prepaid Expenses”
Austin Risk: City bonds (e.g., $500 for plumbers) are REFUNDABLE ASSETS. Mislabeling → IRS disallows deductions + Travis County fines.
Fix: Use Asset Account #1810 “Utility Bonds Receivable.”
Mistake #3: Ignoring “County-Specific Overhead”
Austin Risk: Williamson County projects (e.g., Leander) vs. Travis County (e.g., Bee Cave) have different tax rates/permits. Mixing overhead = job cost inaccuracy.
Fix: Add sub-accounts like #7001 “Overhead – Travis” and #7002 “Overhead – Williamson.”
