TAX PLANNING · SEPTEMBER 9, 2026 · 5 MINUTE READ

ORIGINAL LEAD STORY · SEPTEMBER 15, 2026 DEADLINE HAS PASSED

The September 15 Estimated-Tax Deadline Is Almost Here.

Self-employed taxpayers and business owners should review their 2026 income now—not wait until filing season to discover a payment shortage.

The third estimated-tax payment for calendar-year 2026 is due September 15, 2026. Estimated payments may apply when taxes are not being withheld—or when withholding is not enough—from income such as self-employment earnings, interest, dividends, capital gains, prizes and other taxable income.

Individuals, including sole proprietors, partners and S corporation shareholders, generally need to make estimated payments when they expect to owe at least $1,000 when their return is filed. Corporations generally use a $500 threshold. Your actual requirement depends on your income, deductions, credits, withholding and individual tax circumstances.

Waiting until tax season does not automatically prevent a penalty. The IRS explains that taxpayers may face an underpayment penalty when payments are late or insufficient—even when the eventual return shows a refund. If your income has changed during the year, your estimate should be recalculated instead of automatically repeating an earlier payment amount.

A tax deadline is easier to manage when the numbers are reviewed before the deadline arrives.

Payments may be made through an IRS Online Account, IRS Direct Pay, EFTPS and other official IRS payment methods. Keep confirmation of every payment with your tax records.

TAX LAW UPDATE · AUGUST 2026

The Qualified Overtime Deduction: What the IRS Clarified

The IRS issued updated guidance in August 2026 concerning the new deduction for qualified overtime compensation. The deduction is available to certain workers receiving overtime compensation required under the Fair Labor Standards Act. It may be claimed whether the taxpayer itemizes deductions or uses the standard deduction.

The maximum deduction is generally $12,500 on an individual return or $25,000 on a joint return. The benefit begins to decrease when modified adjusted gross income exceeds $150,000—or $300,000 for joint filers. Importantly, the deduction does not automatically apply to every dollar labeled “overtime.” Generally, it concerns the overtime premium required under federal law, not the worker’s complete overtime wages.

Beginning with tax year 2026, employers generally report qualified overtime compensation separately on Form W-2 in Box 12 using Code TT. Workers should retain their year-end forms and avoid estimating eligibility based only on the amount of overtime shown on a paystub.

GIG ECONOMY · 2026 UPDATE

Five Tax Changes Gig Workers Should Understand

Eligible gig workers may qualify for a deduction of up to $25,000 in qualified tips for tax years 2025 through 2028. For a self-employed worker, the deduction is limited by net income from the applicable trade or business, and reporting requirements still matter.

The federal Form 1099-K reporting threshold has returned to more than $20,000 and more than 200 transactions. That threshold determines when certain payment platforms must issue the form; it does not determine whether income is taxable. Business and gig income must still be reported even when no Form 1099-K is received.

The qualified business income deduction is now permanent, and certain qualifying business property acquired after January 19, 2025 may qualify for 100% bonus depreciation. Eligibility depends on the property, timing and percentage of business use.

CONSUMER AWARENESS · FILING SEASON

A “Fast Refund” Promise Is Not the Same as Professional Tax Work

The IRS is warning taxpayers to be cautious of preparers who use new tax-law changes to promise inflated refunds, guaranteed results or “special loopholes.” A legitimate tax benefit depends on the taxpayer’s facts, documents and legal eligibility.

Paid federal tax-return preparers are required to have a valid Preparer Tax Identification Number and include it on returns they prepare. Other warning signs include refusing to sign the return, requesting cash without a receipt, charging fees based on a percentage of the refund or directing a refund into an improper account.

When preparation fees or other authorized charges will be paid from a refund, the taxpayer should receive a clear explanation of the fees, deductions and disbursement process before agreeing.

SMALL BUSINESS · BEFORE FOURTH QUARTER

Your Year-End Cleanup Should Begin Before the Year Ends

September is a practical time for business owners to review income, expenses, bank activity, receipts and outstanding records. Waiting until filing season can make it harder to identify missing transactions, separate personal expenses and reconstruct business activity accurately.

According to the IRS, reliable records help businesses monitor progress, prepare financial statements, identify sources of income, track deductible expenses, prepare tax returns and support the amounts reported on those returns.

Your system does not have to be unnecessarily complicated, but it should clearly document income and expenses. Accounts should be reconciled regularly, receipts should be stored consistently and unanswered bookkeeping questions should be addressed while the information is still available.
