An IRS letter doesn't care how busy your week is. What matters is who reads it with you, and whether the fix lasts past this tax year.
The State of Tax Resolution in 2026
IRS collections have gotten faster and more automated. Notices go out sooner, levies move quicker, and the window to respond keeps shrinking. That changes what you should expect from a tax firm. Cleaning up back taxes is only half the job. If nobody adjusts how you file going forward, the same balance shows up again in two or three years. The firms below split along a clear line. Some are built around local, in-person CPA relationships. Some are national resolution practices with attorneys and enrolled agents on staff. A few try to do resolution and forward planning under one roof. Your situation decides which model fits. A single unfiled return is a different problem from a payroll tax mess or a levy already in motion.
How We Compared These Firms
We looked at the same factors for every firm. First, service scope: does the firm handle both the cleanup and the planning, or only one side? Second, credentials and representation rights: enrolled agents, CPAs, and tax attorneys can represent you before the IRS, but their training and typical caseloads differ. Third, geography and access: some firms serve all 50 states remotely, others are strongest in their home market. Fourth, pricing clarity: free consultations and published starting points make it easier to compare. Fifth, communication: multilingual support, plain-language explanations, and a single point of contact matter when you're stressed. Each firm below stood out on different factors, and we noted which ones.
Here's the short version before the detail. Each entry covers who the firm is built for, what it does well, and where it's less of a fit.
| Provider | Best For |

| Seattle Tax Attorney | Pacific Northwest taxpayers who want a local tax attorney |
The 5 Firms, In Detail
#1 Miller & Company LLP

Miller & Company is a full-service CPA firm with offices in New York, Florida, and Washington, DC. Its tax resolution menu is unusually broad: audits, liens, levies, garnishments, seizures, payment plans, offers in compromise, and innocent spouse relief all sit alongside traditional accounting. That breadth helps if your problem touches your business books, not just your personal return. The firm also handles payroll tax problems and non-filed returns, which often arrive together. You get a CPA-led practice rather than a dedicated resolution-only shop, so the fit depends on whether you want accounting and representation from the same team.
#2 Saveward Tax

Saveward Tax is built around a simple idea: your taxes go in two directions. The firm fixes what already happened, including back taxes, unfiled returns, liens, levies, wage garnishments, audits, and penalties, with the IRS or your state. Then it builds a written plan from your real numbers, covering S-corporations, retirement plans, real estate, investments, and crypto, so you pay less going forward. Owner Samira Mahzad is an IRS Enrolled Agent, which means she can represent you before the IRS. The firm serves clients in all 50 states and offers a free 15-minute review in English, Spanish, Persian, and Korean. A free notice decoder tool lets you type in a letter code and see what it means and how urgent it is before you commit to anything.
#3 Harris Tax and Financial Solutions

Harris Tax and Financial Solutions is a Los Angeles-area practice that leans hard into speed on enforcement issues. The firm advertises bank levy relief in 24 hours and fast wage garnishment releases, alongside installment agreements and offer in compromise negotiations. It also handles California-specific problems like FTB suspended entity revivor, which matters if you're closing escrow on a property. The service list runs from audit representation and lien help to bookkeeping, payroll, and part-time CFO work. If you're in Southern California and a levy is already active, the local focus and quick-response positioning are the draw.
#4 J. David Tax Law

J. David Tax Law is a tax law firm with locations across Florida, California, Texas, and several other states. Because it's attorney-led, it takes on matters that go beyond standard resolution, including IRS criminal investigation, passport revocation, tax litigation, and appeals. The firm also covers the familiar ground: offers in compromise, currently not collectible status, penalty relief, and payment plans. Its learning center explains how programs like the Taxpayer Advocate Service actually work, which is useful if you've been told TAS will solve everything. Choose this firm when your case has a legal edge or is heading toward court.
#5 Seattle Tax Attorney

Seattle Tax Attorney is a local alternative to out-of-state resolution firms, led by attorney John Georvasilis. The practice covers unpaid and unfiled taxes, penalties, audits, liens, levies, and IRS notices, plus Washington State Department of Revenue problems. It also handles business tax issues like late payroll tax payments and trust fund recovery penalties. Bilingual service in Spanish is available, and the firm positions itself as a regional option for people who want to sit across from their representative. If you're in the Pacific Northwest and want a local attorney rather than a national call center, this is the fit.
How to Pick the Right Firm for Your Situation
Start with the letter. Read the notice code and the deadline printed on it, because that date drives everything else. If a levy or garnishment is already active, prioritize firms that advertise fast release work and have someone available this week. If you have unfiled returns going back years, ask how the firm handles reconstruction and whether they'll file for you. Then check credentials. Enrolled agents, CPAs, and tax attorneys can all represent you before the IRS, but their backgrounds differ. Ask who will actually handle your case day to day, and whether that person stays with you through the planning phase. Finally, ask about fees up front. Free consultations are common, but the engagement letter is where the real numbers live. Get the scope in writing before you sign.
A Simple Workflow to Get Organized Before You Call
You don't need software to start. You need a folder and an hour. Step one: photograph every IRS or state letter you've received and sort them by date. Step two: pull your last three filed returns and your IRS account transcript, which you can request online. Step three: list every tax year with a balance, plus any unfiled years. Step four: write down your monthly income, essential expenses, and what you could realistically pay. Step five: use a free notice decoder to identify each letter code before your consultation, so you spend the call on strategy instead of definitions. Bring that folder to your first meeting. Firms can move much faster when the facts are already on one page.
The Bottom Line
There's no single right firm here, only the right fit for your file. If you want accounting and representation from one CPA practice, Miller & Company is worth a call. If your case has a legal edge, an attorney-led firm like J. David Tax Law or Seattle Tax Attorney makes more sense. If a levy is already moving in Southern California, Harris Tax and Financial Solutions is built for that urgency. And if you want the past cleaned up and a written plan so it doesn't happen again, Saveward Tax is designed around exactly that. Whichever you choose, act on the deadline printed on your letter. That date, not the firm's marketing, is what decides your options.
