Which contract accounting method should my company use?

It depends on your gross receipts and the length of your contracts. Companies below the small-contractor threshold, on contracts expected to finish within two years, may have a choice that gives real control over which year revenue lands in. Larger companies are generally required to use percentage-of-completion. Knowing which side of the threshold you are on is the first step.

Why can reducing my taxable income hurt my bonding capacity?

Sureties set bonding capacity from your reported financial statements, so a strategy that lowers taxable income can also lower the financial picture a surety relies on and cost you a job. The two goals genuinely pull against each other, which is why the strategy has to be designed around the statements the surety needs to see.

Are my subcontractors correctly classified?

Construction sees the subcontractor-versus-employee question examined more aggressively than almost any industry. Classification turns on how the worker actually operates, not on the label. Getting it wrong exposes the company to payroll tax, penalties, and interest, so it is worth reviewing deliberately.

How should I handle taxes for crews working in other states?

Crews crossing state lines can create income-tax and withholding obligations in each state, and apportionment determines how income is split among them. These obligations are easy to miss and accrue quietly, so a multi-state review is worthwhile once work regularly happens outside your home state.

How do I avoid paying tax on retainage I haven't collected?

Retainage and disputed progress billings should be matched to your revenue-recognition method so income is not reported before the money is due or received. A monthly job-cost close keeps the recognition accurate, which is what prevents tax on cash you have not actually collected.

Tax Strategy for Construction Companies

Construction and infrastructure companies overpay primarily through contract accounting method — whether revenue is recognised as work progresses or at completion — which is often chosen by default rather than by analysis. Equipment depreciation, energy-efficiency deductions on qualifying projects, and multi-state apportionment for crews working across state lines are the next largest levers.

Key points

Long-term contract accounting generally requires percentage-of-completion, with a small-contractor exception below a gross-receipts threshold for contracts expected to finish within two years.
Most contractors do not know which side of the small-contractor gross-receipts threshold they are on, which is the first thing to establish.
Reducing taxable income can also lower the financial statements a surety relies on, shrinking bonding capacity and costing the company work.
Subcontractor-versus-employee classification is examined more aggressively in construction than in almost any other industry.
Retainage and disputed progress billings should be matched to the recognition method so tax is not paid on money not yet received.

Why do businesses in this segment overpay?

Long-term contract accounting generally requires the percentage-of-completion method, but a small-contractor exception exists for companies below a gross-receipts threshold on contracts expected to finish within two years. Where it applies, that exception gives real control over which year revenue lands in — yet most contractors do not know which side of the threshold they are on.

Equipment is the second-largest item on the balance sheet after receivables, and its depreciation treatment is frequently unplanned. Crews cross state lines and create income-tax and withholding obligations nobody registered for. And bonding capacity depends on reported financial statements, which creates a genuine tension with tax minimisation that almost no generalist accountant will surface: a strategy that reduces taxable income can also reduce bonding capacity and cost the company a job. That tension is real, and naming it is the honest thing to do.

Which strategies matter most here?

Law changing — verify before acting

The energy-efficiency deductions for commercial buildings and for new residential units were terminated by the One Big Beautiful Bill Act for projects beginning construction or units acquired after a window that closes in 2026. Treat this as a closing window rather than an open, standing lever, and confirm the exact dates before relying on it.

Requires capital outlay

Some of the levers above need cash to fund; the others are elections, timing, and compensation design. A plan separates the two.

What does the IRS look at in this segment?

Contract method changes and the look-back method on completed long-term contracts are the technical heart of a construction examination. Worker classification — subcontractor versus employee — is examined more aggressively in construction than in almost any other industry, and the exposure runs to payroll tax, penalties, and interest.

Related-party equipment leasing between an operating company and an owner's equipment entity draws attention, as does job-cost allocation. These are the areas where the paper trail and the method choice decide whether a position holds.

What changes as you grow?

Below the small-contractor threshold, method choice is the main lever. Crossing it forces percentage-of-completion on most contracts and shifts the work toward equipment planning and multi-state issues.

At the larger end, bonding and surety constraints come to dominate the conversation, and tax strategy has to be designed around the financial statements the surety needs to see. That is exactly the kind of cross-discipline problem a compliance-only preparer cannot solve, because the tax result and the bonding result pull against each other and have to be balanced deliberately. Retainage and disputed progress billings should be matched to the recognition method so the company does not pay tax on money it has not received, supported by a monthly job-cost close and an audit file for large equipment deductions.
