First Year in Business: A New Jersey Tax Checklist for New LLC Owners

Confirm how your LLC is taxed

By default, a single-member LLC is taxed as a sole proprietorship and a multi-member LLC as a partnership, both pass-through structures reported on your personal return. Some owners elect S-Corp or C-Corp taxation instead. It's worth confirming, early, which classification applies to you, since it affects which forms you'll file and how your income is taxed.

Get an EIN if you need one

An Employer Identification Number is generally required if you have employees, are taxed as a corporation, or have a multi-member LLC. Even single-member LLCs without employees often get one anyway, since it's frequently required to open a business bank account and keeps your Social Security number off business documents.

Separate your business finances from day one

Opening a dedicated business bank account and, ideally, a business credit card, from the very start avoids the common first-year problem of a year's worth of tangled personal and business transactions that have to be untangled at tax time. This is far easier to set up correctly at the beginning than to fix later.

Register for New Jersey state tax obligations

Depending on your business activity, you may need to register with the New Jersey Division of Revenue and Enterprise Services for state tax purposes, including sales tax if you sell taxable goods or services. This is separate from your federal EIN and easy to overlook when you're focused on getting the business itself running.

Start estimated tax payments once there's real profit

New businesses don't always turn a profit right away, and you generally don't owe estimated tax on losses. Once your business is consistently profitable, though, quarterly estimated payments become relevant, and starting them proactively, rather than being caught off guard by a large bill the following April, makes the first profitable year far less stressful.

Keep records built for a return you haven't filed yet

Your first business tax return is the one where good habits matter most, because there's no prior year's return to fall back on for reference. Tracking startup costs, equipment purchases, and early expenses carefully in year one makes that first return, and every one after it, considerably easier to prepare accurately.
