Your finances,
finally working
for you

Most business owners find out what they owe in April. My clients know in January — and they've already done something about it. That's the difference proactive accounting makes.

The questions that keep
business owners up at night

These aren't hypothetical. They're the exact things my clients said before we started working together.

"I have no idea what I owe until April."
Tax Surprise Risk Flying blind on your tax liability means overpaying all year or getting blindsided with a bill you can't cover. Proactive quarterly planning eliminates both — permanently.
"My books are somewhere. Probably fine."
Disorganized Records Disorganized finances mean missed deductions, inaccurate reports, and real stress during filing — or if you're ever audited. Clean books are your first line of defense.
"My accountant just files my return. That's it."
Reactive Accounting A reactive accountant costs you money. You deserve someone who looks ahead, asks the right questions, and brings strategies — not just a tax return in April.
"I spend hours every week on admin."
Time Drain Your time has a dollar value. Every hour spent on payroll, invoicing, and reconciliation is an hour you're not growing your business. There's a better use of your time.
"Am I even structured the right way?"
Entity Strategy The wrong business entity could be costing you thousands in self-employment tax every year. Entity structure is one of the highest-leverage financial decisions you'll ever make.
"Is my business actually profitable?"
No Financial Clarity Revenue isn't profit. Without clean monthly financials, every decision — pricing, hiring, spending — is a guess. You deserve to know exactly where you stand, every month.

Advisory-Level Tax Preparation

Your return, handled with care and precision

This isn't a drop-off-and-file service. Every return I prepare includes a personalized advisory package — specific notes, findings, and action steps tailored to your situation. You'll understand exactly what was filed and why, plus what you can do differently going forward.

I don't skip over details that might affect you, and I don't mention things that don't apply. What you get is a thorough, precise review of your tax picture — and a practitioner who will follow through with you throughout the year.

How pricing works
Every return starts with a free consultation where we review your situation together. Pricing is based on the forms, schedules, and depth of work your return requires — the more moving parts, the more time and care it takes to do it right. A single W-2 return starts at $500. Your exact quote is provided before we begin, so there are no surprises.

Rental properties (number, complexity, activity)
Investments, stock sales, crypto transactions
