Understand the 2026 Tax Law Changes

The One Big Beautiful Bill Act (Public Law 119-21) brings big changes that will affect your 2026 tax filing. You can maximize savings and avoid last-minute issues by understanding these updates now.

Key updates from the One Big Beautiful Bill Act

The most important change is the restoration of 100% bonus depreciation for qualified property plus higher Section 179 limits. Many contractors can deduct up to $2.50 million under Section 179 in 2025, with a phase-out starting at $4.00 million. On top of that, it adds an exception to the percentage-of-completion method for certain residential construction contracts that could simplify your accounting.

The law creates new income exemptions. Qualifying tips and overtime pay will be exempt from federal income tax. These will still be subject to employer payroll taxes like FICA, FUTA, and Workers' Compensation.

How the new tax bill affects residential contractors

Residential contractors get a major benefit through the expanded exception from the percentage-of-completion method. This now covers all residential construction contracts instead of just buildings with four or fewer units. The expansion includes apartment buildings, condominiums, student housing, and long-term care facilities.

So if you work on qualifying residential projects, you might use simpler accounting methods. You should work with your CPA to update your Work-in-Progress reporting and contract documentation.

What's changing for deductions and credits

Equipment write-offs are just the start. The bill introduces temporary deductions for qualified overtime compensation (up to $12,500 for individuals or $25,000 for married couples filing jointly). These benefits phase out at modified adjusted gross income thresholds of $150,000 (single) or $300,000 (joint).

A temporary vehicle loan interest deduction (up to $10,000 annually) becomes available for personal-use vehicles purchased after December 31, 2024. The deduction phases out if your modified adjusted gross income exceeds $100,000 ($200,000 for joint filers).

Several clean-energy incentives will phase out, including the §179D commercial buildings deduction for projects starting after June 30, 2026. New business-interest-limitation rules could affect your annual loan interest deductions.

Maximize Deductions with Smart Contractor Recordkeeping

Tax law changes in 2026 will make proper recordkeeping your best ally to maximize deductions. A well-organized system for business records makes tax filing easier and helps you claim every dollar you deserve.

Section 179 vs full expensing: What to choose

Two powerful options for writing off equipment purchases will be available in 2025:

• Section 179: Allows deductions up to $2.50 million with a phase-out threshold starting at $4.00 million. You can choose to apply this selectively to specific assets.

• 100% Bonus Depreciation: Applies to qualified property acquired and placed in service after January 19, 2025. Eligible property classes get this automatically unless you decide against it.

Section 179 works best for specific items because it lets you pick and choose assets. This flexibility helps especially when dealing with states that don't follow bonus depreciation rules. Bonus depreciation requires you to apply it to entire property classes - you must take all or nothing.

Tracking placed-in-service dates for equipment

The IRS says property is "placed in service" once it's ready for specific business use—even if you haven't started using it. This crucial date determines your deduction eligibility, especially for bonus depreciation.

Your records should show both when you bought the equipment and when you placed it in service. The delivery date isn't enough—you need proof of when the equipment became operational.

Residential contractor recordkeeping best practices

A centralized record management system should track contracts, permits, financial statements, insurance policies, tax records, and employment data. Someone specific needs to manage these documents to maintain accountability.

How to handle software and tool purchases

Tools that last less than a year usually qualify for immediate full deduction. Business software qualifies for Section 179 if it helps generate revenue and is accessible to more people—not custom-built.

Large equipment that counts as business assets like cement mixers and compressors need depreciation over time unless you use Section 179 or bonus depreciation.

New Income Exemptions: Tips, Overtime, and Vehicle Interest

The One Big Beautiful Bill Act offers three valuable income exemptions that can slash your 2026 tax burden. You can save money right away if you know how to claim these provisions correctly.

How to claim the no-tax-on-tips deduction

If you have a tipped job, you can deduct up to $25,000 of qualified tips annually from your taxable income. You'll still need to pay Social Security and Medicare taxes on these tips, but they won't be subject to federal income tax. This above-the-line deduction works whatever deduction method you choose - itemized or standard.

To claim this deduction:

• Your tips must appear on Form W-2, 1099 forms, or Form 4137

• You need daily tip logs to validate amounts received

• Your job must be listed in Treasury-designated tipped categories

Overtime pay deduction rules and limits

Starting January 1, 2025, you can deduct qualifying overtime pay up to $12,500 if you file individually or $25,000 for married couples filing jointly. The deduction only covers the premium portion of overtime pay—usually the "half" part of "time-and-a-half" compensation.

Let's say your overtime statement shows $15,000 total. Your deductible amount would be $5,000 (one-third of the total). Note that only overtime required under the Fair Labor Standards Act qualifies.

Vehicle loan interest deduction: What qualifies

Between 2025-2028, you can deduct up to $10,000 annually in interest paid on qualifying vehicle loans. Your vehicle must be:

• New (not used)

• Bought for personal use

• Under 14,000 pounds gross vehicle weight

• Assembled in the United States

Who qualifies and how to report it

These three deductions have specific income thresholds where they phase out. The phase-out for overtime and tips starts at $150,000 MAGI if you file single and $300,000 for joint filers. Vehicle loan interest deductions begin to phase out at $100,000 for single filers and $200,000 for joint filers.

You should keep documentation from your employer or lender showing qualifying amounts for 2025. By 2026, employers and lenders will provide specific forms with these amounts.

IRS Forms Simple Checklist for 2026 Tax Season

IRS forms can feel overwhelming. Let me share a simple checklist to help you get ready for the 2026 tax season and make sure you have all the vital documents.

Form W-2 and 1099-NEC: What's required

The year 2026 brings changes to business requirements. Companies need to issue Form 1099-NEC only when contractor payments go above $2,000 (up from $600). This change cuts down paperwork by a lot for small businesses. But contractors need to report their entire income whatever forms they receive. Employee W-2 forms stay the same and show wages plus reported tips.

Form 4137 for tip income reporting

You'll need Form 4137 if you got tips that your employer didn't know about or if you see allocated tips in box 8 of your W-2. This simple one-page form helps calculate extra Social Security and Medicare taxes you owe on unreported tip income. Note that Medicare tax applies to all unreported tips—even those under $20.

Form 1099-K changes and thresholds

Payment app users can breathe easier! The Form 1099-K threshold is back to $20,000 AND 200+ transactions. PayPal, Venmo and other third-party payment processors will send this form only if you hit both these numbers.

Where to find and file the right IRS forms

The IRS makes things easier with its free electronic filing service through the Information Returns Intake System (IRIS) Taxpayer Portal. Small businesses find this secure platform particularly helpful since it needs no special software. Most forms are due by January 31, 2026, and Copy B must reach recipients by the same date.

Conclusion

The 2026 tax season brings good news for contractors with changes that can reduce your tax burden by a lot. The doubling of Section 179 expensing to $2.5 million and restored 100% bonus depreciation create new ways to save. Residential contractors can now enjoy broader exceptions from the percentage-of-completion method, which makes accounting simpler in housing projects of all sizes.

Your most powerful tool to maximize these tax advantages is smart recordkeeping. Tracking placed-in-service dates and keeping proper documentation will make a big difference at filing time. You'll need to understand which deduction method works best for your situation.

Working contractors will see immediate benefits from the new income exemptions. Qualified overtime pay deductions up to $12,500, tax-free tips, and vehicle loan interest deductions will boost your bottom line. These benefits phase out at specific income thresholds, so you'll need careful financial planning.

The right IRS forms will make your tax preparation smoother. Small contracting businesses will appreciate simpler reporting requirements for 1099-NEC forms. The 1099-K thresholds have returned to $20,000 AND 200+ transactions, which reduces paperwork hassles.

This piece should help you guide through the changing tax rules with confidence. Understanding these provisions now helps you claim every available deduction when 2026 arrives. A little preparation today can save thousands tomorrow and give you more resources to invest in your contracting business's future.
