Questions from Geneva clients

Do you meet clients from Geneva in person?

Yes. We meet by appointment at our office at 4260 Westbrook Dr, Suite 107, Aurora, and we also work by phone, video and our secure online portal, whichever is easier for you.

I live in Geneva but work in Wisconsin, Iowa, Michigan or Kentucky. How are my taxes handled?

Illinois has wage reciprocity agreements with Iowa, Kentucky, Michigan and Wisconsin, which generally means you pay income tax only to Illinois on those wages if you give your employer the right exemption form. We help you set it up and file correctly.

Can you help Geneva small businesses with payroll and sales tax?

Yes. We run payroll with Illinois withholding and unemployment registration, file Illinois sales tax returns, and handle the state and federal returns for the business.

Let's talk about your taxes, your business, your plans.

Tell us what you need and we will get back to you quickly. There is no pressure: just a friendly conversation and a clear next step.

  • You can put up to $24,500 of your pay into a 401(k), 403(b) or TSP in 2026. At 50 or older you can add $8,000, and at ages 60 to 63 you can add $11,250 (up to $35,750 in all). IRS: 2026 retirement limits →
  • Work for yourself with no employees? A solo 401(k) lets you save $24,500 as the "employee" and add an employer contribution on top, for up to $72,000 in total before catch-up. A SEP-IRA has the same top limit. IRS: One-participant 401(k) plans →
  • A SEP-IRA can be opened and funded as late as your tax filing deadline, including extensions. That makes it one of the best last-minute ways for a self-employed person to lower the tax bill. IRS: SEP plans →
  • You can put $7,500 in an IRA for 2026, or $8,600 if you are 50 or older, and you have until the April 2027 filing deadline to do it. IRS: IRA contribution limits →
  • A SIMPLE IRA is an easy retirement plan for a small business. Employees can defer $17,000 in 2026, $21,000 at 50 or older, and $22,250 at ages 60 to 63. IRS: SIMPLE IRA plans →

  • A defined benefit or cash balance plan can let a business owner with steady, high income put away far more than a 401(k) allows, especially after 50. The yearly benefit limit for 2026 is $290,000. IRS: Defined benefit plans →
  • New in 2026: if your Social Security wages from the employer that sponsors your 401(k) were over $150,000 in 2025, your catch-up contributions must go in as Roth (after-tax) money. IRS: 2026 retirement limits →
  • If your income is modest, the saver's credit can cut your tax bill by up to $1,000 ($2,000 for a couple) just for saving for retirement. For 2026 it reaches incomes up to $40,250 single and $80,500 joint. IRS: Saver's credit →

  • Estimated taxes are due four times a year: April 15, June 15, September 15 and January 15. Paying 100% of last year's tax (110% if your income was over $150,000) usually protects you from the underpayment penalty. IRS: Estimated taxes →
  • The business mileage rate rose to 76 cents a mile on July 1, 2026 (it was 72.5 cents from January to June). A simple log of dates, miles and purpose is what turns miles into a deduction. IRS: Standard mileage rates →

  • If you are self-employed, the health insurance premiums you pay for yourself, your spouse and your dependents may be deductible even if you do not itemize, up to your net profit. IRS: Self-employed health insurance →

  • S corporation owners who work in the business must pay themselves a reasonable salary. Too low, and the IRS can recharacterize distributions as wages and charge payroll tax and penalties. IRS: S corporation compensation →
  • Illinois lets partnerships and S corporations elect to pay Illinois tax at the entity level. The owners can then get a federal deduction that works around the $40,400 cap on state and local taxes. Illinois tax guide →

  • Not filing costs ten times more than not paying: 5% of the unpaid tax per month (up to 25%) against 0.5% per month. If you cannot pay, still file on time. IRS: Failure to file penalty →
  • An extension to file is not an extension to pay. Pay what you expect to owe by the original due date to avoid penalties and interest. IRS: Extension to file →
  • You may qualify for IRS first-time penalty abatement if you filed and paid on time for the past three years. Ask before you pay a penalty. IRS: Penalty relief →
  • A Notice of Deficiency gives you 90 days (150 if you are outside the U.S.) to challenge the IRS in Tax Court before the tax is assessed. The date is on the letter and it cannot be extended. If you got an IRS letter →
