One of the first surprises for a new business owner is discovering that the money spent getting the business off the ground is not simply deductible in the year it was spent.
You registered the LLC, paid a lawyer, ran market research, leased space, trained staff, built a website — all before you had a single customer. It feels like an expense. For tax purposes, most of it is not treated as one, at least not immediately. Knowing the rules before you spend is worth real money, and knowing them after you have spent is still worth quite a lot.
Start-up costs are generally capitalized rather than deducted — meaning they sit on the balance sheet and are recovered over time rather than reducing this year’s income.
The exception is the one most people have heard of: you may elect to deduct up to $5,000 of start-up costs in the year the business begins operating, with the remainder amortized over 180 months.
The part people have usually not heard: that $5,000 begins to phase out dollar for dollar once total start-up costs exceed $50,000. Spend $52,000 and the immediate deduction drops to $3,000. Spend $55,000 or more and it disappears entirely — everything is amortized.
There is also a timing trigger worth understanding. The deduction is available in the year the business begins active operations, not the year you started spending. A business that incurs costs across two calendar years before opening does not get to deduct in the earlier one.
What counts as a start-up cost
Start-up costs are amounts you spend investigating or creating a business, which would have been deductible as ordinary business expenses if the business had already been up and running. In practice that usually includes:
- Market research and feasibility analysis
- Advertising and pre-opening promotion
- Wages paid to employees being trained, and their instructors
- Travel to line up suppliers, customers or distributors
- Professional and consulting fees connected to getting started
Just as important is what does not belong in this bucket. Equipment, vehicles and other depreciable property follow their own rules. Inventory is inventory. Interest and taxes are deductible under their own provisions. Land and buildings are capital assets. Putting these in the start-up pile is a common and costly error, because several of them have far more favourable treatment available — including Section 179 and bonus depreciation on qualifying equipment.
Organizational costs are a separate bucket
Organizational costs — the expenses of actually forming the entity — are handled separately from start-up costs, though the mechanics look similar: up to $5,000 deductible in year one, the same $50,000 phase-out, the rest amortized over 180 months.
These include state filing fees, the legal work of drafting articles of organization or incorporation, operating or partnership agreements, and organizational meeting costs. In Wisconsin that means your DFI filing fees and the attorney time behind the formation documents.
Because the two categories each carry their own $5,000 allowance, tracking them separately from the very first invoice is worth doing. Lumped together into one “startup” account, the distinction is lost and so, frequently, is part of the deduction.
The mistake that costs new owners the most
The expensive mistake is almost never choosing the wrong election. It is not keeping the records.
Pre-opening spending typically happens on personal cards, from personal accounts, months before a business bank account exists. By the time the first return is prepared, the owner has a shoebox and a vague memory. Costs that were genuinely deductible get missed entirely, and costs that were capital get claimed as expenses.
What to do instead, and none of it is difficult:
- Open the business bank account early and run pre-opening costs through it where you can
- If you must pay personally, log it immediately as an owner contribution with a description
- Keep start-up and organizational costs in two separate accounts from day one
- Write down the date the business actually began operating — that date drives the election
- Keep the invoices, not just the card statements; a statement line does not establish what was purchased
If you are launching a business in southeastern Wisconsin, or you opened in the last year or two and suspect the early costs were never handled properly, that is worth a conversation before the next return. You can book a 30-minute call and we will look at what you have.
Every situation is a little different. A short conversation will tell you whether any of this actually affects you — and exactly what to do about it if it does.
