If you’re running a pass-through entity in Maryland, understanding the Maryland Pass-Through Entity Tax (PTE Tax) is essential for ensuring your business stays compliant and minimizes its tax burden. The Maryland Pass-Through Entity Tax is a state-level tax that affects businesses structured as S-corporations, partnerships, and limited liability companies (LLCs). The tax allows the owners of pass-through entities to bypass the individual state income tax on their business income by paying taxes at the entity level. While this tax structure is beneficial for many small business owners, it can be complex to understand without the right information. In this article, we’ll dive deep into the Maryland Pass-Through Entity Tax, explain its purpose, eligibility, and how to file, so you can ensure your business meets all the requirements and avoids unnecessary penalties.
What is the Maryland Pass-Through Entity Tax?
The Maryland Pass-Through Entity Tax is a tax designed for business owners who operate pass-through entities. A pass-through entity refers to a business where the income or losses are “passed through” to the owners and reported on their personal income tax returns. These entities do not pay income tax at the business level; instead, the owners report their share of income on their individual returns. Examples of pass-through entities include partnerships, S-corporations, and LLCs that elect to be taxed as a partnership.
Maryland’s Pass-Through Entity Tax came into effect in 2018 and was designed to counteract the impact of the Tax Cuts and Jobs Act of 2017, which capped the state and local tax (SALT) deduction for individuals at $10,000. The PTE tax allows businesses to pay state taxes at the entity level, which helps owners bypass the federal cap on SALT deductions, providing significant savings for some.

Who is Eligible for Maryland Pass-Through Entity Tax?
The Maryland Pass-Through Entity Tax applies to most pass-through entities that are subject to Maryland income tax. However, it’s important to note that the tax is optional for most businesses. It is primarily designed for businesses that are S-corporations or partnerships, as these entities typically pass their income and losses to individual owners, who then report them on their personal tax returns.
To be eligible for the PTE tax, businesses must elect to participate in the tax by filing the appropriate form with the Maryland Comptroller’s Office. This tax election is typically made on the business’s annual income tax return. Business owners should carefully review their tax situation to determine whether electing the PTE tax is beneficial based on their specific financial circumstances.
How Does the Maryland Pass-Through Entity Tax Work?
Once a pass-through entity elects to pay the Maryland Pass-Through Entity Tax, it is required to file a PTE tax return (Form 510) with the Maryland Comptroller’s Office. The business will then pay taxes on its income at the entity level, rather than having the income passed through to the owners. This tax rate is currently set at 8.25% on the income earned by the business, which is the corporate income tax rate in Maryland.
By paying the tax at the entity level, business owners can avoid the individual state income tax on their share of business income. For example, if you are an owner of an S-corporation and your business elects to pay the PTE tax, the business pays the tax, and you don’t have to report your share of income on your personal Maryland income tax return. This helps avoid the SALT deduction cap at the federal level, providing potential savings for higher-income earners.
Benefits of Maryland Pass-Through Entity Tax
- Bypassing the SALT Deduction Cap: One of the biggest benefits of the PTE tax is that it allows business owners to bypass the $10,000 cap on state and local tax deductions set by the Tax Cuts and Jobs Act. Since the tax is paid at the entity level, the owners are able to claim the full amount as a deduction on their federal tax return.
- Tax Savings for Higher-Income Earners: For business owners who earn substantial income through their pass-through entity, the PTE tax can result in significant federal tax savings. By paying taxes at the entity level, owners can avoid paying higher individual state income taxes, especially if they reside in states with high state income tax rates.
- Easier Filing for Multi-State Businesses: Businesses with owners located in different states can benefit from the PTE tax by simplifying the filing process. Instead of each owner having to file individual returns in different states, the tax is paid at the business level, reducing the complexity of state tax filings.

How to File Maryland Pass-Through Entity Tax
To file the Maryland Pass-Through Entity Tax, businesses must follow these steps:
- Complete the Maryland Pass-Through Entity Tax Election: The business must file an election form with the Maryland Comptroller’s Office. This is typically done when the business files its annual income tax return (Form 510).
- File the PTE Tax Return (Form 510): After electing the PTE tax, the business must submit the PTE tax return each year to report its income and pay the tax. The return is due by the 15th day of the 4th month after the end of the business’s tax year.
- Distribute Payment to the Business Owners: After paying the tax, the business will distribute any remaining income to its owners. The owners will report their share of income on their personal income tax returns, but they will not be subject to Maryland state income tax on their share of business income.
- Maintain Records: Keep accurate records of the taxes paid and the income distributed to each owner. This will help ensure that you are in compliance with Maryland tax laws and will simplify the process of filing your personal income tax return.
Common Mistakes to Avoid When Filing Maryland Pass-Through Entity Tax
- Not Filing the Election: Failing to file the election form for the PTE tax can result in missed tax benefits. Be sure to file the appropriate form when required.
- Incorrect Income Reporting: Ensure that all business income is accurately reported on the PTE tax return. Misreporting income can lead to penalties and additional taxes.
- Missed Filing Deadlines: The PTE tax return has a strict filing deadline. Missing this deadline can result in penalties and interest, so it’s important to file on time.
