I'm Sarah Mitchell, Certified Public Accountant & Enrolled Agent
Taxes shouldn't keep you up at night. My job is to make sure they don't.
I started SWP Tax Consultant after years at a large accounting firm, where clients often felt like a file number. Here, you work with the same advisor every year — someone who knows your history, remembers your goals and spots savings before you have to ask.
Precise Work, Plain Answers and an Advisor Who Knows You
Most of our clients come by referral and stay for years. They tell us it's because we explain things clearly, return calls the same day and treat their money like our own.

Client stories
What Our Clients Say After Tax Season
★★★★★
I'd been doing my own taxes for my design studio for years. Sarah found deductions I'd missed for three years running and amended my returns. The refund paid for her fees twice over.
Emily RodriguezFreelance graphic designer
★★★★★
We received an audit letter and panicked. The team took over the same week, organized every receipt and the case closed with no change. Calm, clear and completely on our side.
Daniel KowalskiRestaurant owner, Springfield
★★★★★
Four years of unfiled returns felt impossible to fix. They filed every year in a month, got the penalties reduced and set up a payment plan I can actually afford.
Priya ShahNurse practitioner, Chicago
★★★★★
Switching our S-corp to them was the best decision we made last year. Quarterly check-ins mean April is now a non-event, and payroll just runs.

Common questions
Answers Before You Book
Still unsure whether you need a professional? These are the questions we hear most often from new clients.
Prefer to talk it through?
Call during office hours and speak with an advisor, not a call center.
Usually your W-2s or 1099s, last year's return, ID for everyone on the return, and records of deductions such as mortgage interest, childcare, charitable gifts and business expenses. After your consultation, we send a checklist tailored to you.
Can you help if I haven't filed for several years?
Yes. We regularly prepare multiple years of unfiled returns, calculate what's actually owed and negotiate payment plans or penalty relief where it's available.
Do I need to visit your office in person?
No. Most clients work with us entirely online through the secure portal and video calls. You're always welcome to meet in our Springfield office if you prefer.
How long does it take to prepare my return?
Personal returns are typically ready for review within 5–7 business days of receiving complete documents. Business returns take longer depending on the state of the books.
What happens if the IRS questions a return you prepared?
We respond on your behalf at no extra cost for returns we prepared, and if a penalty results from our error, we pay it under our accuracy guarantee.
How do I pay, and when?
We confirm a flat fee before starting. Payment is due when you approve your final return, by card, bank transfer or check. Payment plans are available for larger business engagements.
