How much does it cost to start a Wisconsin LLC?
The biggest cost is the $130 filing fee for Articles of Organization with the Wisconsin Department of Financial Institutions. This is the document that officially creates your LLC. You can file online and it typically processes within a few business days.
After that, Wisconsin requires an annual report filed every year for $25. Your first one is due in the calendar quarter of your LLC’s formation anniversary. It’s a simple form confirming your business address and registered agent information, but missing it can result in your LLC being administratively dissolved by the state.
You’ll also need a federal Employer Identification Number from the IRS. This is free. Apply online at irs.gov and you’ll receive it immediately. You need an EIN to open a business bank account, hire employees, and file taxes as your LLC.
Every Wisconsin LLC must have a registered agent with a physical address in the state. You can serve as your own registered agent at no cost, which is what most solo business owners do. If you’d rather not have your personal address on public records or you want someone else handling legal mail, third-party registered agent services run $100 to $300 per year.
If your business will sell physical products or certain taxable services, you’ll need a Wisconsin sellers permit from the Department of Revenue. The state filing fee is $20. This allows you to collect and remit sales tax legally.
An operating agreement isn’t required by Wisconsin law, but you should have one even as a single-member LLC. It documents how the business operates and strengthens your liability protection. You can draft a basic one yourself for free or pay an attorney a few hundred dollars for something more thorough.
Adding it all up, most owners form a Wisconsin LLC for under $200 when they serve as their own registered agent and file everything themselves. That covers the $130 Articles of Organization, a $25 annual report, and the EIN at no charge. A sellers permit and registered agent service push the number higher but are only needed in certain situations.
What you want to avoid is paying $500 or more to an online formation service for work you can do yourself in an afternoon. Those companies charge premium prices for the same state filings and often upsell add-ons you don’t need. If you’d rather have help, business formation through a local provider who knows Wisconsin requirements is a better use of your money.
Once your LLC is filed, the next step is setting up your books correctly from day one. Separating personal and business finances immediately, opening a business bank account, and tracking income and expenses from the start saves you from expensive cleanup later. Wisconsin small business bookkeeping services can help you build that foundation so your new LLC runs on solid numbers from the beginning.

How do surveyors depreciate field equipment like GPS and total stations?
GPS units, total stations, and similar survey equipment are typically capitalized and depreciated over 5 years using MACRS. Section 179 lets you expense the full cost in year one if that makes more sense for your tax situation.
Read answerWhat inventory method should a small retailer use — FIFO or average cost?
Most small retailers should use average cost. It's simpler, it's what QuickBooks Online calculates automatically, and the difference in accuracy compared to FIFO is minimal for typical retail operations. Consistency over time matters more than the method you pick.
Read answerHow do retailers account for vendor discounts and rebates?
Discounts received at the time of purchase reduce inventory cost using the net price method. Volume rebates earned after the fact reduce cost of goods sold when received. Neither should be recorded as other income.
Read answerShould a landscaping business use cash or accrual accounting?
Most landscaping businesses do well on cash basis accounting. It's simpler, widely accepted, and works especially well for maintenance-focused operations with short billing cycles. Accrual becomes worth considering when you regularly take on large installation projects that span multiple weeks or months.

Separate revenue by contract type (monthly service, on-call, project), track direct labor and materials per contract, and make sure work orders flow into your job costing. Recurring contracts should be clearly visible as monthly recurring revenue.
