How many lines are on Schedule C?

Schedule C Part II (Expenses) has 22 numbered lines covering the most common business expense categories, plus Line 27 (other expenses) for anything else. Part III covers COGS for product businesses.

What is the most commonly missed Schedule C deduction?

The home office deduction (Line 30) is the most commonly missed. Any freelancer who uses a dedicated space exclusively for work can claim it — even renters. The simplified method is $5/sq ft up to 300 sq ft ($1,500 max).

Can software subscriptions go on Schedule C?

Yes — software subscriptions used for your business go on Line 22 (supplies) or Line 18 (office expense). Examples: Notion, Figma, Adobe Creative Cloud, Grammarly, Zoom.

What is the meals deduction limit on Schedule C?

Business meals are 50% deductible on Schedule C Line 24b. The meal must have a clear business purpose and you must keep a receipt. Entertainment expenses (concerts, sports) are no longer deductible as of the 2018 TCJA.

Do I need receipts for every Schedule C deduction?

The IRS requires records 'sufficient to establish' each deduction. For amounts under $75 (except lodging), no receipt is technically required — but keeping all receipts is strongly recommended. CentSense stores and categorizes them automatically.

Part III: Cost of Goods Sold (Product Businesses)

If you sell physical products (Etsy sellers, Amazon sellers, makers), you also complete Part III:

Line	Description
36	Inventory at beginning of year
37	Purchases during the year
39	Materials and supplies
42	Inventory at end of year
43	COGS (Line 41 minus Line 42)

COGS is subtracted from gross receipts before you get to your net profit. Every dollar of material cost you track reduces your taxable income by a full dollar.

Deep-Dive Guides by Line

Line 8: Advertising Expenses

Facebook ads, Google ads, business cards, website hosting, domain registration, sponsorships, and any paid promotion. All 100% deductible.

Line 11: Contract Labor and 1099-NEC

Payments to independent contractors. $600+ triggers a 1099-NEC filing requirement. Covers VAs, designers, editors, and any non-employee you pay for services.

Line 22: Supplies and Software Subscriptions

Software subscriptions, office supplies, packaging materials, and tools under $2,500. Notion, Figma, Adobe Creative Cloud, Zoom — all 100% deductible here.

Line 24b: Business Meals (50% Rule)

Client lunches, working dinners, meals while traveling. Always 50% — not 100%. Entertainment (concerts, sports) is 0% deductible since 2018.

Line 30: Home Office Deduction

The most missed deduction. Dedicated space used exclusively for work. Simplified method: $5/sq ft up to 300 sq ft ($1,500 max). No Form 8829 required.

The Lines Most Freelancers Get Wrong

Line 24b at 100% instead of 50%

Business meals are 50% deductible. CentSense automatically applies the 50% rule to restaurant receipts in your export.

Line 25 at 100% for a personal phone

You can only deduct the business-use percentage of your phone bill. Estimate your business use (e.g., 70%) and apply it. Only a dedicated business-only phone gets 100%.

Claiming Line 30 for a non-dedicated space

The home office deduction requires exclusive and regular use. A guest bedroom or kitchen table doesn't qualify. A dedicated room used only for work does.

Missing Line 9 (mileage) entirely

Every business mile is $0.725 in deductions in 2026. A freelancer who drives 6,000 business miles deducts $4,350. Most forget to track in real time — CentSense logs it per trip.
