Thienel Law handles the tax side of running a company, from entity taxation and elections to multi-state exposure, for business owners across Maryland, Washington, D.C., and Virginia, from one attorney with an LL.M. in Taxation who also prepares the returns.
Business tax is the ongoing cost of operating a company: how the entity is taxed, which elections apply, and what each state and the District collect. For owners in the DMV, that cost is shaped by decisions made all year, not just at filing. Thienel Law advises owners on the tax consequences of how their business is structured and run, as part of the firm’s wider tax practice. Because Stephen Thienel holds an LL.M. in Taxation, is licensed in Maryland, D.C., and Virginia, and prepares returns in-house, the legal analysis and the filing that reports it come from one attorney. That matters most when a business touches more than one jurisdiction, where the same profit can be taxed differently depending on where it is earned.
What is business tax, and which owners need a lawyer for it?
Business tax is the set of rules that determine how a company’s income is taxed: at the entity level, at the owner level, or both, and by which government. It is legal work as much as accounting work, because the answer turns on the entity form, the elections in place, and where the business operates. A tax attorney reads how those rules apply to a specific business and structures the decision, while a preparer reports the result after the fact.
The owners who benefit most are the ones making a choice with a lasting tax effect. New businesses selecting a structure, growing companies crossing into a second state, and owners planning a sale or a transfer to the next generation all face business tax questions where the legal framing changes the bill. If your company operates in more than one DMV jurisdiction, the case for advice is stronger.
What goes wrong when business tax is an afterthought?
The tax treatment of a business is set by choices that are easy to make without advice: the entity form, an election checked or missed, where the company registers and earns. Each of those choices repeats. An entity taxed the wrong way carries the cost into every year until someone restructures it.
A missed election can be hard to reverse once its deadline passes. A business that expands across a state line often picks up a new filing obligation, and a new tax, without noticing the line was crossed. By the time a return is prepared, most of these are already fixed. The expensive version of business tax is the one handled only after the year closes.
What does business tax work with Thienel Law cover?
Business tax is handled around how your company actually operates, not a generic checklist. The work commonly covers:
- Choosing and electing the entity’s tax treatment, so profit is taxed the way the owners intend.
- Advising on how the business is classified for tax, as an S corporation, partnership, or disregarded entity, and the elections that set it.
- Mapping multi-state and District tax exposure when a business operates in more than one DMV jurisdiction.
- Handling the tax terms inside contracts, sales, and financing before they are signed.
- Coordinating owner compensation, distributions, and reasonable-salary questions.
- Aligning the business tax picture with the owner’s estate and succession plan.
You work under clear terms agreed up front, so the cost of the work is known before it begins.
What is it like to work with Steve on business tax?
Every engagement starts with a free 30-minute consultation. It is a fit conversation for owners who are ready to hire a tax attorney: you describe what your business is facing, and you and Steve decide together whether working with him makes sense. From there you work directly with Stephen Thienel, not an associate you never met.
The practice runs online. Secure document sharing, electronic signatures, and video meetings let you send over the operating agreement or the deal and move it forward from wherever your business is based. Because Stephen prepares returns in-house, the same attorney who advises on the structure can handle the filing that reports it.
How do Maryland, D.C., and Virginia tax a business differently?
The DMV looks like one market, but a business inside it can face three different tax systems, and an entity form that is fine in one can cost more in another.
Washington, D.C. is the outlier. The District levies a franchise tax on the taxable income of unincorporated businesses, subject to statutory exemptions, so a sole proprietorship, partnership, or single-member LLC working in the District can owe an entity-level tax the same business would not owe across the river. Virginia taxes at the entity level in a narrower way, through its income tax on corporations doing business in the Commonwealth, while generally taxing other business income in the owners’ hands. Maryland adds a layer the other two do not: every county imposes a county income tax on its residents on top of the state tax, so a pass-through owner’s bill depends partly on the county they call home. Because Stephen is licensed in all three jurisdictions and works with the IRS, one attorney can plan for the whole footprint instead of a single piece of it.
Where does business tax connect to your other legal needs?
A company’s tax life is tied to how it was formed, the contracts it signs, and the plans its owners have for it.

Frequently asked questions
What does a business tax attorney do that my accountant does not?
A business tax attorney interprets how the law applies to a decision and structures it, with attorney-client privilege, while an accountant records and files what already happened. The lawyer handles entity elections, multi-state exposure, and the tax terms inside contracts before they are signed. Stephen Thienel does both jobs, because he practices tax law and prepares returns, so the advice and the filing stay consistent.
How is my business taxed in Maryland, D.C., and Virginia?
It depends on the entity form and where the business operates. Washington, D.C. taxes unincorporated businesses at the entity level, Virginia taxes corporations at the entity level, and Maryland layers a county income tax on resident owners on top of the state tax. Because each jurisdiction is different, a company operating in more than one can owe tax it did not expect.
Does my business need a tax attorney or a CPA?
Many businesses use both, for different work. A CPA keeps the books and prepares returns, while a tax attorney provides legal analysis, structures decisions, and can represent the business in a dispute with privilege a CPA cannot offer. Stephen prepares returns in-house as well, so a business can get the legal and the filing side from one office.
When should a business owner bring in a tax attorney?
Before a decision with a lasting tax effect is final. Choosing an entity, making or missing an election, expanding into a new state, or planning a sale all set tax consequences that are hard to change afterward. Getting advice while the choice is still open usually costs less than fixing the result later.
Can one attorney handle my business tax across all three DMV jurisdictions?
Yes. Stephen Thienel is licensed in Maryland, Washington, D.C., and Virginia and works with the IRS, so he can advise a business that operates in one jurisdiction or all three. That matters because a structure that works in one can create an unexpected tax in another.
Ready to get your business tax handled by one attorney?
Stephen Thienel advises DMV business owners on how their company is taxed, structures the decisions that set the bill, and prepares the returns that report them, across Maryland, D.C., and Virginia.
