Expense Tracker for Freelance Writers

Software, home office, research costs — auto-mapped to Schedule C.

Freelance writers have some of the most varied deductions in the self-employed world: writing software, home office space, research books, courses, interview travel, and subscription services. CentSense maps every receipt to the correct Schedule C line automatically.

Software Subscriptions: The Undertracked Deduction

Most freelance writers pay $50–$150/month in software subscriptions and claim less than half of it. Here's a complete list of what's deductible:

  • Writing tools: Grammarly, Hemingway, ProWritingAid, Scrivener, Final Draft
  • Research and notes: Notion, Evernote, Roam, Obsidian
  • Storage and file sharing: Dropbox, Google Drive (paid), iCloud (business portion)
  • Communication: Zoom, Slack (if for client communication)
  • Project management: Asana, Trello, ClickUp
  • AI writing tools: ChatGPT Plus, Claude Pro — deductible when used for client work

Every one of these goes on Line 22 (Supplies) or Line 18 (Office Expense). CentSense AI scans the receipt and assigns it automatically.

Home Office: The Biggest Missed Deduction

If you write from a dedicated room or space, the home office deduction is often the largest single line item on a writer's Schedule C.

Two methods:

MethodHow It WorksBest For
Simplified$5 × sq ft, max 300 sq ft ($1,500)Easy to calculate, safe
ActualHome-office % × (rent + utilities + insurance)Can be larger, more documentation

The space must be used exclusively and regularly for business. A corner of your bedroom doesn't qualify. A dedicated writing room does.


Client Projects: Know Which Clients Are Worth It

The Solo plan ($5/month) includes client projects. Create one project per publication, agency, or retainer client. CentSense rolls all expenses (research, subscriptions, travel) up per project — so you can see whether a $2,000/month retainer is actually profitable after software and travel costs.
