June 15 Tax Check for Trades Businesses: 2026 1099, Mileage, and Overtime Updates

If you own an HVAC, plumbing, electrical, roofing, landscaping, flooring, cleaning, or contracting business, use the weeks before June 15, 2026 to clean up the numbers that decide whether your tax plan is real.

The quick take

Before the June 15, 2026 estimated tax deadline, trades owners should review five areas:

• Q2 estimated tax: Update the payment using year-to-date profit through May 31, with April and May isolated, not last quarter's gut feel.
• 1099 workflow: The IRS FAQ references a higher threshold for payments made after Dec. 31, 2025, but you still need clean vendor records.
• Mileage logs: The 2026 business mileage rate is 72.5 cents per mile, but the deduction only works when business miles are documented.
• Overtime reporting: 2026 payroll files need cleaner separation of qualified overtime compensation.
• Job costing: Trucks, subs, overtime, and materials should be tied back to job margin before tax cash leaves the account.

This is not about chasing a deduction after the fact. It is about making sure your books, payroll, and cash routing can support the decisions you are about to make.

Why June 15 matters for trades businesses

The IRS estimated tax calendar is not a normal quarterly calendar. For 2026, IRS Publication 505 lists the second estimated tax payment period as April 1 through May 31, with payment due June 15, 2026.

That timing matters because many trades businesses are in a distorted window by mid-June:

• Spring work may have increased revenue but not collected cash.
• Material costs may have hit before customer payments cleared.
• Payroll and overtime may have jumped during busy weeks.
• Subcontractor costs may be sitting in uncategorized transactions.
• Truck and fuel costs may be buried in owner cards or mixed accounts.

If your estimate is based only on bank balance, you can overpay and starve operations, or underpay and create a later surprise. The better input is a current year-to-date profit and loss statement through May 31, a clean balance sheet, and a short cash forecast.

If your books are not ready for that, the first fix is not a tax trick. It is a tighter monthly accounting cadence.

1. Recheck the Q2 estimated payment using year-to-date profit through May 31

Many owners make estimated tax payments from fear:

• "Last year hurt, so send more."
• "Cash is tight, so send less."
• "Revenue is up, so taxes must be up."

Those shortcuts break quickly in trades businesses because revenue and profit do not move together.

A plumbing company can have a record revenue month and weak profit because of overtime, callbacks, parts runs, and uncollected invoices. A roofing contractor can show strong deposits while still carrying project costs and retainage risk. A landscaping business can hit a seasonal revenue peak while equipment repairs and field payroll are spiking at the same time.

Before June 15, ask for a clean package that shows year-to-date results through May 31, plus April and May by month:

• Profit and loss by month
• Balance sheet with loans, credit cards, payroll liabilities, and tax accounts
• Accounts receivable aging
• Accounts payable and supplier balances
• Owner draws and payroll
• Job-cost reports for labor, materials, subs, and equipment

Then compare your estimated tax options:

• Prior-year safe harbor
• Current-year projection
• Rolling profit and loss method
• Annualized income installment method for uneven seasonal income
• Entity-specific strategy for S-Corps, partnerships, Schedule C owners, or C-Corps

Use the Tax Playbook & Estimator if you need a structured starting point, but do not treat a public calculator as a substitute for entity-specific tax advice.

2. Update your 1099 workflow for the 2026 threshold

Trades businesses rely heavily on subcontractors. That makes the 1099 process a profit and compliance issue, not just a January paperwork task.

The IRS Form 1099-NEC and independent contractor FAQ references reporting payments of $600 or more, with a $2,000 threshold for payments made after December 31, 2025. For a 2026 trades business, that means you should revisit your vendor workflow now instead of waiting for year-end.

Do not misunderstand the threshold.

The reporting threshold is not:

• permission to stop collecting W-9s,
• a rule that makes smaller payments nondeductible,
• a worker-classification test,
• or a reason to mix subcontractor labor with materials and supplies.

Your workflow should still capture:

• W-9 before first payment
• legal name, DBA, address, and taxpayer identification number
• payment method and total paid year to date
• whether the vendor is a corporation, LLC, individual, or partnership
• labor vs. materials when invoices include both
• insurance certificates and subcontractor agreements when relevant

For trades owners, the practical rule is simple: if someone touches your job cost, your books should know who they are, what job they worked on, and how much of the payment was labor.

3. Fix mileage logs before the truck deduction becomes a guessing game

The IRS announced the 2026 optional standard mileage rate for business use at 72.5 cents per mile. That is useful for contractors with service vans, sales vehicles, estimator trucks, or owner vehicles used for job sites and supplier runs.

But the rate does not solve the hardest part.

The hard part is proving business use.

For trades businesses, a usable vehicle record normally needs:

• date,
• business purpose,
• destination or job/customer reference,
• beginning and ending odometer or tracked business miles,
• vehicle used,
• and separation between commuting, personal errands, and business trips.

You may also need to compare the standard mileage method with actual expenses, especially when vehicles are heavy, financed, wrapped into the business, or tied to equipment-heavy operations. That comparison belongs in your business tax strategy, not in a rushed December text thread.

The June 15 checkpoint is a good time to answer three questions:

• Are all business vehicles in the books?
• Are mileage logs being captured every week?
• Are fuel, repairs, insurance, lease payments, and loan payments categorized correctly?

If not, fix the recordkeeping now while the trips are still recent.

4. Make overtime visible in payroll and job costing

Trades owners are hearing a lot about the qualified overtime deduction. The planning issue is not only whether an employee gets an income tax benefit. The owner-side issue is whether payroll and job costing can show what happened.

The IRS qualified overtime FAQ says that, for tax years 2026 and later, employers and other payers are required to separately report qualified overtime compensation. The Department of Labor also reminds employers that covered, nonexempt employees must generally receive overtime pay for hours worked over 40 in a workweek at not less than one and one-half times the regular rate.

Two details matter before you communicate this to employees. First, qualified overtime compensation is generally the FLSA-required premium above the regular rate, not the entire overtime paycheck. Second, the deduction is capped and phases down at higher modified adjusted gross income levels. Treat it as payroll reporting plus employee communication, not a promise that overtime is fully tax-free.

That creates two separate owner responsibilities:

• Wage and hour: classify workers correctly, track time, and pay overtime where required.
• Tax and reporting: make sure payroll reports can identify regular wages, overtime, and qualified overtime information.

It also creates a margin question. If overtime is happening because dispatch is overloaded, estimates are under-scoped, or callbacks are high, the tax deduction conversation is missing the bigger leak.

Use this review:

• Which jobs generated the most overtime?
• Was it schedule compression, poor estimating, warranty work, or missing labor capacity?
• Did pricing cover the true labor cost?
• Did the payroll system separate regular and overtime pay cleanly?
• Did your job-cost report show overtime by job, department, or crew?

5. Tie the tax check to job margin, not just deductions

The best June 15 review is not "How do we lower this payment?"

The better question is:

What did the business actually earn, and where is the cash?

For trades businesses, tax planning gets weak when these items are disconnected:

This is where tax strategy and cash-flow strategy overlap. If the tax account is empty, the problem may be pricing, collections, job costing, owner draws, or missing reserve routing.

Use the Profit Routing Calculator to separate tax cash from operating cash, reserves, growth, and owner wealth.

The 15-minute owner review this week

Set aside 15 minutes with your office manager, bookkeeper, controller, or CPA and answer these questions:

• Do April and May books show real profit, or just deposits and expenses?
• What Q2 estimate method are we using, and why?
• Which subcontractors have crossed the 2026 reporting threshold or may cross it soon?
• Do we have W-9s before payments go out?
• Are truck miles documented weekly?
• Are actual vehicle costs being categorized consistently?
• Can payroll report regular wages and overtime clearly?
• Which jobs lost margin because of overtime, callbacks, or material overruns?
• How much cash is already reserved for taxes?
• Will the June 15 payment weaken payroll, supplier payments, or reserves?

If the answers are fuzzy, do not wait until year-end. The value of this checkpoint is that you still have more than half the year to fix the system.

What not to do

Do not treat the new 1099 threshold as a reason to ignore vendor records. You still need clean support for deductions, and workers still have their own income reporting obligations.

Do not estimate taxes from gross revenue. A busy trades business can have thin profit when labor, materials, callbacks, and debt service are considered.

Do not assume overtime is "tax-free." It is a deduction with limits and reporting mechanics, and it does not remove wage and hour obligations.

Do not wait until December to reconstruct truck miles. Mileage logs are strongest when they are current, specific, and tied to business purpose.

What to do next

If you own a trades or home-service business, make June 15 a system checkpoint:

1. Close April and May books.
2. Review profit, cash, receivables, and tax reserves.
3. Clean up W-9s, subcontractor payments, and job assignments.
4. Confirm mileage and vehicle records.
5. Audit overtime reporting and job-level margin.
6. Set or adjust the Q2 estimated payment with current numbers.

For industry-specific planning, start with the relevant guide: accounting for HVAC contractors, bookkeeping for plumbing contractors, or tax planning for electrical contractors.
