Starting a business is one of the most important decisions you will make. The legal structure you choose affects your taxes, your personal liability, and how your business operates for years to come. Getting the formation right from the beginning saves you time, money, and legal trouble down the road.
At Kostrub Law Firm, PLLC, we help entrepreneurs and small business owners in Pittsburgh, Cecil, and the surrounding areas set up their businesses on solid legal ground. Our attorneys walk you through every step of the formation process and make sure your business is structured to protect your interests.


The type of business entity you choose determines how you are taxed, how much personal liability you carry, and how decisions are made within the company. Choosing the wrong structure can leave your personal assets exposed to business debts or result in higher taxes than necessary.
Some of the most common business structures include:
Each structure has its own filing requirements, tax treatment, and legal obligations. Our attorneys help you compare the options and choose the one that fits your business and your goals.

Forming a business involves more than just filing paperwork with the state. There are several steps that need to be completed correctly to make sure your business is legally recognized and properly organized.
The typical formation process includes:
Skipping any of these steps can create problems later. Our attorneys handle the process from start to finish so nothing is overlooked.
One of the main reasons to form a business entity is to protect your personal assets. If your business is properly structured and maintained, your personal home, savings, and other property are generally shielded from business-related claims and debts.
However, this protection only works if you follow the rules. You need to keep your business and personal finances separate, maintain proper records, and follow the governance requirements of your entity type. If you mix personal and business funds or fail to hold required meetings, a court may disregard your business structure and hold you personally liable.
At Kostrub Law Firm, we make sure you know what is required to maintain your liability protection. We set up your business with the right documents and advise you on how to stay in compliance going forward.
