What we do

Tax returns are the whole job — not a sideline

We focus on preparation. That narrow focus is the point: it is what lets us be precise about the details that decide whether a return is right.

Individual Returns

Federal and state returns for individuals and families, including itemized deductions, investment income, and life changes that complicate a filing year.

Small Business

Schedule C, partnerships, S corporations, and single-member LLCs — with the individual's personal return handled alongside the business so the two agree.

Current Year Filing

This season's return, prepared and reviewed before it is filed. Extensions handled when more time is the smarter call.

Past Due & Unfiled

Returns you have fallen behind on — one year or many. We work through them in the right order and get you current.

Past due returns

Behind on filing? That is fixable.

Unfiled returns tend to get heavier the longer they sit. Most people who call us have been putting it off for a while, and nearly all of them are surprised at how straightforward the path back is once someone maps it out.

We file past due returns in the order that makes sense, using what records you still have — and we tell you plainly what we need from you before we start.

01

Any number of years

One missed year or a decade of them — the approach is the same, just longer.

02

Missing paperwork is normal

Lost W-2s and 1099s are the rule, not the exception. We work from what can be obtained and reconstructed.

03

Filed correctly, not just filed

A rushed catch-up filing can cost more than it saves. Accuracy is the whole point of doing this properly.

04

Part of a larger strategy

If unfiled returns are tied to a balance owed, getting current is usually the first step toward resolving it.

How it works

A straightforward process

No portals to figure out before you have even spoken to anyone. It starts with a conversation.

Step 01

Call us

Tell us what you need filed and what shape your records are in. We will tell you what the work involves.

Step 02

Send documents

We give you a specific list — not a generic checklist — so you are not guessing at what matters.

Step 03

We prepare

Your return is prepared and then reviewed. Questions come back to you before anything is finalized.

Step 04

You approve, we file

Nothing is submitted until you have seen it and signed off. You keep a complete copy.
