Although the October 15 deadline has already passed for those who requested a tax extension, this month is still key for your finances.
Between health insurance and Medicare open enrollment, year-end tax planning and real estate and business opportunities, this is the ideal time to review, adjust and get ready for 2026.
Here's a summary with up-to-date data and practical steps to make the most of the rest of the year.
1οΈβ£ Taxes: if you didn't file on time, you still can
- Deadline passed: October 15, 2025 was the final deadline for those who requested an extension with Form 4868.
- What if you didn't file? You can still file. The longer you wait, the higher the penalties and interest will be. The failure-to-file penalty is 5% per month of the unpaid balance (up to 25%), while the failure-to-pay penalty is only 0.5%.
- If you're expecting a refund, there's no penalty, but filing is how you get it.
- Tip: Use this time to review deductions and adjust your withholding for 2026.
π‘ How we help you:
An express review of your pending return, penalty calculation, an IRS payment plan and a tax projection for next year.
2οΈβ£ Health insurance (ACA/Obamacare) and Medicare: open enrollment season
- ACA/Obamacare: Open enrollment starts on November 1 and ends on January 15. If you want coverage active starting January 1, 2026, it's best to enroll before mid-December.
- Fact: In 2024, enrollment reached a record 21.3 million people, thanks to tax credits that lower the monthly premium cost.
- Medicare: The annual enrollment period is open from October 15 through December 7. It's your chance to compare plans, doctor networks and prescription drug costs.
π‘ How we help you:
Free quotes, plan comparisons and subsidy estimates based on your household income.
3οΈβ£ Real estate: time for strategic analysis
- Mortgage rates: Although they remain above pre-pandemic levels, there are adjustments and specific opportunities. A 1 percentage point change can shift the monthly payment on a typical loan by as much as 10-12%.
- Fall opportunities: Less competition and more flexible sellers can create room to negotiate prices or closing costs.
- Strategy: If you're looking for a lower monthly payment, you can negotiate βpointsβ to reduce your rate. If you prefer a smaller upfront payment, there are FHA options and assistance programs.
π‘ How we help you:
Tax pre-qualification, payment simulations and guidance to choose the most convenient loan and structure.
4οΈβ£ Small business owners: plan before year-end
- Fact: The entrepreneurial spirit remains strong: more than 5.5 million new business applications were filed in the U.S. in 2023.
- Actions for OctoberβDecember:
- Review your books and cash flow to schedule deductible expenses.
- Evaluate whether it makes sense to structure your company as an LLC or S-Corp before the 2026 tax year.
- Adjust your last estimated payment (January) to avoid penalties.
π‘ How we help you:
A 30-minute tax assessment, LLC/S-Corp setup, and deduction and payroll planning.
5οΈβ£ Immigration and taxes: keep your documents ready
- USCIS updated its fees in 2024. Keeping your taxes up to date can make processes such as permanent residency, naturalization or work permits easier.
- Fact: About 900,000 people become naturalized citizens every year. Many forms, such as the I-864 (Affidavit of Support), require recent tax returns.
π‘ How we help you:
We coordinate your immigration strategy with your taxes so your forms are complete and free of financial errors.
