Small business startup costs tax deduction: what to separate before tax prep

Starting a business is rarely tidy. You may pay for ads before your first sale, buy tools before your first customer, take a training course before your first appointment, or order supplies before your shop opens.

If you are a sole proprietor, freelancer, gig worker, driver, hairdresser, barber, cleaner, seller, creator, consultant, or side hustler, the tax question is not just "Did I spend money?" It is also "Did this happen before the business started, after it started, or for something that needs separate review?"

This guide explains the IRS startup cost idea in plain English, then shows what to separate in Koody before tax season.

What small business startup costs are

What counts as startup costs?

Startup costs are costs you pay before the business actually begins operating. The key is timing: the purchase happened while you were getting ready to open, sell, drive, take clients, or serve customers.

Common startup costs can include:

• Pre-launch advertising.
• Market research or customer research.
• Product research.
• Travel to find suppliers, vendors, or customers.
• Training before you start offering the service.
• Consultant or professional fees for getting the business ready.
• Software, tools, or services used to prepare for launch.
• Licenses, permits, or setup costs that need review.

The important phrase is "before the business actually begins operating." A barber buying supplies before opening a chair, an Etsy seller buying tools before listing products, a therapist paying for practice setup costs before seeing clients, or a rideshare driver paying for setup costs before starting rides may all have records worth separating.

The $5,000 startup cost rule in plain English

Are small business startup costs tax deductible?

The IRS says startup costs are generally capital expenses. That means they are not always treated like regular expenses you deduct right away.

Under the IRS startup cost rule, a business can elect to deduct up to $5,000 of certain startup costs. That $5,000 amount is reduced when total startup costs exceed $50,000. Remaining startup costs may need to be spread out over time through amortization.

In plain English: do not throw every pre-launch purchase into regular expenses and assume it is done. Track the cost clearly, keep the receipt, and let your accountant or tax preparer decide what can be deducted now and what may need to be amortized.

The timing matters too. The remaining costs are generally amortized beginning with the month the business begins. That is why your launch date belongs in your records.

Startup costs vs ordinary business expenses

What is the difference between startup costs and regular business expenses?

Startup costs happen before the business starts operating. Ordinary business expenses happen after the business is already operating.

A purchase can look the same on your bank statement but need different review because of timing:

• Instagram ads before launch may be startup advertising.
• Instagram ads after launch may be regular Marketing & Advertising.
• Training before your first paid client may be part of startup records.
• Training after the business is running may be reviewed as an ordinary business cost.
• Software bought before opening may need a launch-date note.
• Software used every month after opening may be a normal operating cost.

The bank row alone will not explain that timing. A short note can.

Startup costs vs organizational costs

What are organizational costs?

Organizational costs are costs connected to creating a business entity. They are not the same as every cost of starting a business.

Examples may include some legal, accounting, filing, or setup costs tied to forming an LLC, corporation, partnership, or other entity. A sole proprietor who never forms a separate entity may have fewer organizational-cost records, but legal and professional costs should still be tracked clearly.

Keep organizational costs separate from general startup spending. A tax professional can decide whether the $5,000 organizational cost rule applies and how the remaining amount should be handled.

Assets, inventory, and personal purchases

Some pre-launch spending does not belong in the startup-cost pile at all. This is where many new business owners get stuck.

Assets and equipment

Laptops, cameras, salon chairs, tools, furniture, vehicles, machinery, and equipment may be assets. The IRS has separate rules for depreciation, section 179, amortization, and property placed in service.

Do not hide these inside one "startup costs" label. Keep the receipt, date, amount, item description, and business-use note so your accountant can review it.

Inventory and product costs

If you make or buy goods to sell, inventory and cost of goods sold need separate attention. Product costs are not always ordinary expenses, and unsold goods may still be inventory at year end.

For example, an Etsy seller buying blank shirts before launch, a baker buying ingredients for orders, or a reseller buying items to flip should separate product costs from general setup costs. For a deeper product-seller guide, read Schedule C inventory and cost of goods sold.

Personal or mixed purchases

A new business often starts in the same bank account as household spending. One Amazon, Target, Costco, or Home Depot charge may include business setup items, household items, inventory, and office supplies.

Koody lets you split one transaction across multiple categories, so the business part can go to startup records and the personal part can stay personal. Add a note when only part of the receipt belongs to the business, so the row is easier to review later.

What records to keep for startup costs

What should I track for small business startup costs?

Keep enough detail for someone to understand what happened without guessing.

• Date: when the money was spent.
• Payee: who you paid.
• Amount: how much you paid.
• Receipt or invoice: what you bought.
• Business purpose: why the purchase was connected to the business.
• Category: advertising, legal, training, travel, software, supplies, inventory, equipment, or another useful bucket.
• Launch-date note: whether the purchase happened before or after the business began operating.
• Asset or inventory note: whether the item may need separate review.
• Split note: whether part of the purchase was personal.

If you are not sure where something belongs, do not force it into a random category. Put the best note you can on the transaction and flag it for review.

How Koody helps before tax prep

Koody helps you turn scattered startup spending into records that are easier to review.

• Import bank and card transactions when you need to catch up.
• Let Koody auto-categorize rows, then review pre-launch rows carefully.
• Separate Marketing & Advertising, Legal & Professional Services, Taxes & Licenses, Supplies, Office Expense, Business Travel, Inventory / Cost of Goods Sold, Other Business Expenses, Transfers, and Owner Draw / Personal.
• Attach receipts, invoices, PDFs, screenshots, order confirmations, and setup documents.
• Add notes for launch date, business purpose, training, supplier research, customer research, and mixed purchases.
• Split a transaction by category when one receipt includes business setup costs, personal items, inventory, and regular supplies.
• Export filtered records when your accountant, tax preparer, or bookkeeper needs them.

Koody is especially useful when you want to manage household money and sole proprietor records in one app. You can keep personal categories and business categories together without pretending every row is the same kind of spending.

What to check before tax prep

Before you send startup records to your accountant or tax preparer, review the rows that commonly cause confusion.

• Launch date: when the business actually began operating.
• Pre-launch vs post-launch spending: whether the purchase happened before or after the business opened.
• Assets and equipment: laptops, tools, furniture, cameras, machinery, vehicles, and other longer-lasting items.
• Inventory: products, materials, ingredients, packaging, and goods bought to sell.
• Organizational costs: legal, accounting, filing, and formation costs tied to creating an entity.
• Interest and taxes: costs that may have separate rules.
• Licenses and permits: costs that may need regular expense, amortization, or other review depending on what they are.
• Mixed purchases: one receipt with business setup items and personal items.
• Missing receipts: invoices, emails, screenshots, order confirmations, bank records, and notes that help rebuild the record.
• Abandoned ideas: costs for a business idea that never opened.

If a row is unclear, attach what you have and write a note. A short note written now is better than trying to remember the business purpose months later.
