About Zimmerman Law, PC — General Practice Bismarck North Dakota
General practice Bismarck businesses and families need an attorney who covers a wide spectrum of legal and financial needs, and Zimmerman Law, PC has built a reputation for handling that spectrum with consistency. The firm operates from its Kirkwood Office Towers location at 919 South 7th Street, serving clients throughout Bismarck and the surrounding Burleigh County region. Zimmerman Law combines law, tax, and accounting services under one roof — a setup that gives clients dealing with business formation, tax preparation, payroll, or legal matters a single trusted resource rather than a fragmented team of separate advisors. Attorney Isaac and the full Zimmerman Law team have earned a loyal, multi-generational client base across the Bismarck area.
The firm’s dual capacity in law and tax is particularly well-suited to the Bismarck market, where a growing small business community and a state with a low flat 2.5% individual income tax rate create specific planning opportunities and compliance demands that a general practice attorney with tax depth can address comprehensively. Clients describe Zimmerman Law as efficient, personable, and genuinely invested in the success of each engagement — qualities that distinguish it in a market where large metro firms are the alternative for many Burleigh County residents.

Frequently Asked Questions
Does North Dakota have a state income tax for individuals?
North Dakota does have an individual income tax, though its rates are among the lowest in the nation. As of 2024, North Dakota reduced its income tax to a flat 2.5% rate for most taxpayers. For businesses, this low-tax environment creates planning opportunities, but compliance with federal tax obligations and multi-state nexus rules still requires careful attention. Zimmerman Law’s combined legal and tax expertise is particularly valuable for clients working through these requirements.
Where are business entity filings handled for Bismarck companies?
Business entities in North Dakota are registered with the North Dakota Secretary of State’s office. LLC and corporation filings can be submitted online or in person, and ongoing annual reports are required to maintain good standing. Zimmerman Law handles the formation process, including drafting operating agreements and bylaws, ensuring new Bismarck businesses start with proper legal documentation in place.
What should a Bismarck business owner look for in a general practice attorney?
A Bismarck business owner benefits most from an attorney who understands both the legal and financial dimensions of running a company — someone who can address entity structure, contracts, and tax planning without sending the client to three separate offices. Zimmerman Law’s integrated law-and-tax model is designed specifically to meet that need, giving Burleigh County business owners a single, coordinated resource for ongoing legal and financial compliance.
