Meet the Founder
Three decades of experience.
One Lynwood neighbor you can call.
Elmer McCaskill founded the practice in 2001 with a simple idea: the people of Lynwood and Chicago's South Suburbs deserve the same caliber of tax guidance once reserved for downtown boardrooms — delivered by someone they actually know.
An accounting graduate of Roosevelt University and a former Arthur Andersen professional, Elmer has spent more than 35 years advising corporations, small businesses, nonprofits, and everyday families through changing tax laws, life transitions, and the financial decisions that shape generations.

"After 35 years in this work, you stop seeing tax returns and start seeing people. My job is to help my Lynwood neighbors make the best decision they can with what's in front of them."
A signature point of view
Taxes have changed.
So should the way you prepare them.
A decade ago, a typical Lynwood household had one W‑2 and a standard deduction. Today, the same household might have a rideshare side hustle, a rental unit in Calumet City, remote work across the Indiana border, and a teenager with their first 1099. Software wasn't built for that. Neighbors were.
✦
Gig economy income
Rideshare, delivery, freelance, creator income — each with its own quirks and deductions most software quietly misses.
✦
Rental properties
Depreciation, repairs vs. improvements, passive loss limits — the rules that separate a profitable rental from an audit headache.
✦
Side businesses
Schedule C, home‑office, mileage, retirement plans for self‑employed — strategy, not just data entry.
✦
Multi‑income households
Two W‑2s, a 1099, a brokerage account, and an HSA. We make all of them line up correctly the first time.
✦
Remote & cross‑border work
Illinois–Indiana lines blur fast. We sort residency, withholding, and state credits before they cost you.
✦
Tax law changes
Brackets, credits, and thresholds move every year. We watch them so you don't have to.
✦
Small business ownership
S‑corp elections, reasonable comp, quarterly estimates — the decisions that shape your tax bill long before April.
✦
Life transitions
Marriage, a new baby, retirement, inheritance, a home sale — every one of them has a tax consequence.
Today's tax returns need guidance, not just software. That's the whole reason this practice exists.
A modern client experience
Technology + Human Intelligence
Software makes the process easier. Expert guidance makes the outcome better. We've built our workflow around both — so you get a calm, paperless experience and a real person who actually knows your situation.

Organized & checked
Your documents land in one tidy place. We confirm what's in, flag what's missing, and ask the questions software never asks.

Who we serve
Built for real‑life tax situations.
Life changes create tax consequences. The right advisor helps you understand both — before they show up on a return.
Gig workers & 1099 earners
Rideshare, delivery, freelance, creator income. We turn shoeboxes of receipts into clean Schedule C strategy.
Rental property owners
South Suburban duplexes and Indiana single‑families. Depreciation, repairs, and passive‑loss rules done right.
Small business owners
Main‑street shops, contractors, consultants. S‑corp elections, quarterly estimates, payroll, and clean books.
Retirees & pre‑retirees
Social Security timing, Roth conversions, RMDs, capital gains — the moves that shape the next 20 years.
Multi‑generational households
Three generations, one return season. We coordinate filings, gifting, and inheritance with one steady hand.
Outcomes, not line items
More than tax preparation.
The goal isn't filing paperwork. The goal is helping you make smarter financial decisions — and feeling settled about the ones you've already made.

Rooted in the South Suburbs
Proud to serve Lynwood and Chicago's South Suburbs.
We're not a downtown tower or a national chain. We're a Lynwood practice — the kind of place where your tax advisor knows your kids' names, your contractor cousin's S‑corp, and the duplex your mom still owns on the Indiana side.
