September Is the Perfect Time for a Tax Checkup
Life changes throughout the year—and your taxes often change right along with it.
September feels like a fresh start. Children are back in school, summer vacations are winding down, football season has begun, and many families are settling into new routines. It is also an excellent time to take a quick look at your finances before the busy holiday season arrives.
Taxes may not be at the top of your September to-do list, but a short checkup now could help you avoid stress, missed opportunities, and unpleasant surprises later.
Has Life Changed Since January?
Think about what has happened in your life during the past nine months. Did you:
- Get married or divorced?
- Welcome a child or begin caring for a dependent?
- Change jobs, receive a raise, or start earning overtime?
- Begin working for yourself or earning money from a side business?
- Buy a vehicle or make a major purchase?
- Retire or begin receiving Social Security?
- Experience a major change in investment or rental income?
These events may affect your withholding, estimated tax payments, deductions, or credits. Waiting until tax season to discuss them may leave fewer planning options.
Check Your Withholding Before Year-End
If you received a raise, changed jobs, worked significant overtime, or added a second source of income, the amount withheld from your paycheck may no longer match your actual tax situation.
There is still time to review your withholding and make an adjustment before December. Employees can submit a new Form W-4 to their employer when a change is needed.
This is especially important for married couples when both spouses work. Each employer may withhold as though that job is the household’s only income, which can sometimes result in too little being withheld overall.
Self-Employed? Review Your Estimated Payments
Business owners, independent contractors, gig workers, landlords, and people receiving substantial investment income may need to make estimated tax payments.
The third federal estimated-tax payment for 2026 was due September 15, and the fourth is due January 15, 2027. If you missed the September payment or your income changed significantly, do not ignore it. Acting promptly may help limit possible penalties and give you time to adjust the next payment.
The IRS generally requires estimated payments when someone expects to owe at least $1,000 after withholding and refundable credits, although individual circumstances and special rules can change the calculation. Review the IRS’s 2026 estimated-tax guidance.
Several 2026 Tax Changes May Affect Everyday Families
This year includes tax provisions that may be relevant to many households. Depending on your income and circumstances, you may qualify for deductions involving:
- Qualified tips
- Qualified overtime compensation
- Interest on certain qualifying personal vehicle loans
- An enhanced deduction for eligible seniors
- Cash contributions to qualifying charities, even when you do not itemize
These provisions have specific definitions, income limits, documentation requirements, and filing rules. A phrase such as “no tax on overtime” does not necessarily mean every dollar of overtime pay is automatically excluded from taxable income. It generally refers to a deduction for qualifying compensation, subject to applicable limits.
The important step now is to begin saving the right records instead of trying to recreate them next spring.
Still Working on Your 2025 Return?
If you requested an extension for your 2025 individual federal tax return, the general filing deadline is October 15, 2026. Remember that an extension to file was not an extension to pay.
The IRS recommends gathering and reviewing documents now rather than waiting until the last minute. If you owe more than you can pay in full, filing the return and addressing the balance is generally better than avoiding the situation. The IRS offers payment options for qualifying taxpayers. Read the IRS guidance for extension filers.
A Simple September Tax Checklist
Before the month ends, consider taking these five steps:
- Review your most recent pay stub and federal withholding.
- Total your year-to-date business or side-job income and expenses.
- Organize receipts for charitable gifts, education costs, major purchases, and business expenses.
- Write down any important family, employment, or financial changes from this year.
- Schedule a tax-planning conversation before the year-end rush begins.
Tax planning is not only for wealthy individuals or large companies. It is for anyone whose life, family, income, or business has changed.
A little attention in September can make the months ahead feel far more manageable.
