Startup Costs for a Reseller: What You Can Deduct Before the Business Opens

Published October 16, 2026 13 min read

A cost paid before your first sale is not automatically deductible as a startup expense. What matters is what the cost was for, whether it belongs to an active business, and how the tax rules treat it.

• Startup costs generally relate to investigating or creating an active trade or business.
• Eligible costs may qualify for a limited deduction and amortization once the business begins.
• Inventory is generally recovered through cost of goods sold when the items sell, not as a startup-cost deduction.
• Equipment may be treated as long-lived property rather than an ordinary expense.
• Clear records help you explain what you bought, why, and when your business began operating.

What counts as a business startup cost

A business startup cost is generally a cost of investigating or creating an active trade or business before it begins operating. For a reseller, the timing alone does not decide whether a cost qualifies: its purpose and how a comparable cost would be treated in an existing business matter too. The business startup costs deduction is not a blanket write-off for everything you spend while planning to sell. Keep the facts about each purchase so you can classify it correctly.

Costs must relate to creating an active trade or business

A potentially eligible startup cost is one connected to investigating or creating a business that you intend to operate for profit. The rule generally looks at whether the cost would have been deductible as an ordinary business expense if you had already been running an active business in the same field. That distinction can make early expenses different from personal purchases, assets, or inventory. For a federal overview of business setup and records, see IRS Publication 583.

Market research and trips to evaluate potential suppliers or markets

Research into whether a resale business could work may be a startup cost when it is genuinely part of investigating or creating the business. That might include comparing potential product categories, studying likely demand, or evaluating sourcing options. A trip needs a clear business purpose; personal sightseeing or unrelated errands do not become business costs because you also considered a supplier. Keep notes of where you went, what you investigated, and how the trip related to the proposed business.

Pre-opening advertising, website setup, and professional advice

Costs to prepare the business for customers can be different from expenses that start only after operations begin. Early advertising, a website, and professional advice may qualify when they relate to creating the active trade or business and would otherwise be deductible operating costs. But a website or other item with lasting value may need separate tax treatment rather than being grouped automatically with startup expenses. This startup-cost deduction rule is a useful framework for sorting the categories before you file.

Personal expenses do not become deductible just because you plan to resell

A purchase remains personal when it serves your personal life rather than the planned business. Clothing you wear, meals you would have bought anyway, or a personal trip do not become deductible simply because you are thinking about reselling. If an expense has both personal and business use, keep the facts that show the business portion and ask a tax professional how to handle the allocation. Business purpose matters more than the date you began planning.

Which early costs resellers commonly face

Resellers commonly face early costs for researching products, preparing a storefront, getting professional help, and learning how to operate. Their tax treatment varies, so it helps to record each cost separately instead of treating every pre-launch payment as one startup-cost total. Keep in mind that buying stock is not the same as paying for market research or advertising. A little care at the start makes the later classification less confusing.

Researching product categories, sourcing options, and selling platforms

Before buying anything, you may spend time comparing product categories, possible suppliers, and places to sell. Costs tied to investigating whether to create a resale business may be startup costs if they meet the relevant rules. Once you are operating, ordinary expenses connected to running that business may be treated differently. For broader examples of reseller expenses, see deductions for resellers.

Setting up a store, branding, and initial promotional materials

A store setup, early branding work, or first promotional materials can be part of preparing a business to operate, but the name on the invoice does not decide the tax treatment. Consider what was purchased, when it was used, and whether it has continuing value. For example, FlowLister writes eBay listings from item photos, with a price taken from sold listings; a listing can become part of the record of what sold. The software mention does not make a related cost automatically deductible, so keep the invoice and note how you used the service.

Fees for legal, accounting, or other professional help

Professional fees may relate to startup activity, ordinary operations, or a separate organizational step. Ask the professional to describe the work on the invoice, especially if one engagement covered several matters. Do not assume that all legal or accounting fees belong in the same tax category. Sorting them by the work performed gives you and your preparer a better basis for deciding how each amount is handled.

Training costs and the limits on deducting education

Training is not automatically deductible just because it helps you feel ready to sell. Education that qualifies you for a new trade or business may be treated differently from instruction that maintains or improves skills used in an existing business. Keep the course description, receipt, and a short note about how the material relates to your activity. If the training is personal or prepares you for a different line of work, do not fold it into the startup-cost total without checking the rule.

How the startup-cost deduction works

The federal startup-cost rules generally allow a limited deduction when the business becomes active, with eligible remaining costs recovered over time. The calculation is not available simply because you paid the bills in an earlier month or year. For tax year 2026, IRS Publication 583 describes the general $5,000 deduction, its reduction when eligible startup costs exceed $50,000, and amortization of remaining eligible costs over 180 months; see IRS Publication 583. These are federal figures and rules, so keep their tax year and source with your records.

The general $5,000 deduction and the $50,000 phaseout threshold

For tax year 2026, the general rule allows an initial deduction up to $5,000, reduced dollar for dollar by the amount that eligible startup costs exceed $50,000. The deduction cannot exceed the eligible costs themselves. As a result, the allowed initial deduction may be smaller than the general limit, or eliminated, when the eligible total is high enough. Confirm the calculation against IRS Publication 583 for tax year 2026 rather than treating the limit as a guaranteed deduction.

Amortizing remaining eligible costs over 180 months

For tax year 2026, eligible startup costs remaining after the initial deduction are generally recovered through amortization over 180 months, as described in IRS Publication 583. Amortization spreads the recovery across the prescribed period instead of deducting the full remaining amount at once. This applies only to costs that meet the startup-cost rules; it does not turn inventory or personal expenses into eligible costs. Keep the total, the amount deducted initially, and the remaining balance together so the calculation can be followed.

When the deduction and amortization period begin

The startup-cost deduction and amortization period generally begin when the active trade or business starts, not automatically on the date you first paid a bill. That is why your records should distinguish planning from actual operations. A reseller may have costs in one tax year and begin operating later, so the payment date alone may not show when recovery starts. See the IRS guidance in Publication 583, and preserve evidence of the business’s operating start.

How to distinguish startup expenses from organizational costs

Startup expenses and organizational costs are separate tax categories, even when both arise before a business opens. Organizational costs relate to forming or organizing a business entity, while startup costs generally relate to investigating or creating the business activity. The rules and eligibility can depend on the entity and the nature of the work. Ask your preparer to separate the categories rather than combining every pre-opening invoice under one label.

How inventory and equipment are treated

Inventory and equipment do not become startup expenses simply because you bought them before opening. Resale stock is generally recovered through cost of goods sold when it sells, while equipment and other property with lasting use may be subject to depreciation or another property rule. Supplies depend on what they are for and how the tax rules treat them. The cost of goods sold guide explains how resellers track item costs and inventory.

Inventory purchases generally become cost of goods sold when items sell

For resale inventory, the cost is generally taken into account through cost of goods sold when the items are sold, rather than as a startup deduction when purchased. Record the item or lot, purchase date, source, and price so you can connect the cost to sales later. Bulk purchases may need a reasonable allocation among the items. Consistent records also help you compare what you paid with the items that actually sold.

Unsold stock is not a startup-cost deduction

Stock still on hand has not become a startup-cost deduction merely because you bought it before the store opened. Its cost generally remains tied to inventory until the goods are sold, subject to the applicable accounting rules. Track unsold items separately from operating expenses, and reconcile your inventory records at year-end. The Schedule C guide for resellers can help you see where gross receipts, inventory, and expenses fit on the return.

Equipment and other long-lived property may require depreciation

A camera, computer, shelving unit, or other item used over time may be treated as property rather than an ordinary startup expense. Depending on the item and applicable rules, its cost may be recovered through depreciation or another permitted treatment. Keep the receipt, purchase date, description, and information about business use. Do not assume that a small-looking purchase or a pre-opening date decides the treatment by itself.

Supplies and small purchases depend on their purpose and tax treatment

Boxes, tape, labels, and other supplies may be ordinary costs of operating a resale business, but a pre-opening purchase still needs to be classified according to its purpose and the relevant tax rules. A useful way to sort early purchases is to separate them by what they do:

This is a recordkeeping guide, not a substitute for classifying a particular item under the rules that apply to your return. Separating the categories now helps prevent inventory costs from being mixed with supplies or equipment.

When the business is considered open

A business is generally considered open when it has begun active operations, not simply when you pick a launch date. Preparing to sell and actually conducting the business can be different stages, and the facts matter. A first sale can be evidence of activity, but it is not necessarily the only relevant marker. Keep a simple record of what was ready and what work you had begun.

Starting active operations matters more than choosing a launch date

A date written on a calendar or announced online does not by itself establish when an active trade or business began. Look instead at what you were doing: whether the business was ready to serve customers and had started its regular activity. For a reseller, that may involve more than one step, such as preparing listings, handling orders, and maintaining business records. Write down the relevant dates while they are fresh rather than reconstructing them much later.

Preparing to sell is different from conducting the business

Research, sourcing, and setup can occur before you are operating. A prepared storefront or a stack of inventory may show progress, but those facts alone may not settle when active operations began. Keep notes that distinguish preparation from the point when you were ready and began carrying on the resale activity. That timeline helps separate startup costs from expenses incurred after opening.

A first sale is not always the only relevant timing marker

A first sale is a clear event to document, but it may not be the only fact relevant to the start of operations. The business may have begun carrying on its activity before the first completed sale, depending on what was ready and underway. Conversely, a plan to sell later does not necessarily mean the business has already opened. Preserve dated evidence rather than relying on a single milestone in isolation.

Keep evidence of when the business became ready and began operating

Useful evidence can include dated listings, order records, business correspondence, and notes showing when you began handling ordinary business tasks. Keep those records together with startup invoices so you can connect the costs to the operating timeline. For a tax-year estimate after you have sales and expenses to work with, you can estimate your tax. An estimate does not determine whether a particular startup cost qualifies.

Records to keep before opening

Good records before opening help you explain each cost, classify it, and support the date your business became active. Keep source documents and a short note about the business purpose, rather than relying on memory at filing time. Separate startup expenses from inventory, equipment, supplies, and personal spending. A consistent recordkeeping routine also makes it easier to discuss uncertain items with a tax professional.

Save receipts, invoices, contracts, and payment records

Keep the original receipt or invoice where possible, along with proof of payment and any contract that explains the work. If the invoice is vague, ask for a clearer description or add a dated note about what the payment covered. Digital copies can help, but make sure you can find them by date and category. The documents should show both the amount paid and the reason for the expense.

Record each cost’s business purpose and purchase date

For every early cost, record the date, amount, seller, what you bought, and why it related to the proposed or active business. For inventory, include the item or lot details needed to connect the purchase to later sales. For travel, preserve the business reason and relevant supporting records. The clearer the purpose, the easier it is to distinguish an eligible business cost from personal spending.

Separate startup costs, inventory, equipment, and personal spending

A separate business bank account can make the trail easier to follow, although the classification still depends on the purchase itself. Use categories that reflect what the cost was for, and do not put unsold stock in the same bucket as advertising or packing supplies. A simple opening ledger can group the records like this:

• Startup research, setup, and qualifying pre-opening services.
• Inventory purchases, tracked by item or lot.
• Equipment and other property used over time.
• Operating supplies and other business expenses.

Review the categories periodically and correct obvious misclassifications while the details are still easy to find. Reseller Taxes is a free guide to US federal taxes for resellers; its reseller tax basics page explains the difference between profit, gross sales, and business costs.

Keep records that support the deduction or amortization calculation

Keep a worksheet showing which costs you included as startup costs, which you excluded, and why. If you claim a deduction and amortize eligible remaining costs, retain the calculation and the source material used to support it. Reseller Taxes also publishes a free self-employment tax calculator for estimating tax from reselling figures; it does not determine startup-cost eligibility or prepare a return. Keep your records, calculation, and tax-year reference available for your preparer.

Conclusion

Before opening, separate the cost of creating the business from inventory, equipment, personal spending, and later operating expenses; then document when active operations began. If you want to plan for tax on reselling profit after you start selling, Reseller Taxes offers a free self-employment tax calculator, alongside guides that explain the federal rules in plain language.
