Tracking income and expenses throughout the year, rather than trying to reconstruct everything at tax time, is the single biggest thing that separates a manageable author tax season from a stressful one, and it doesn't require expensive software or complex bookkeeping to do well. Most of the pain of author taxes comes from poor record-keeping during the year, not from the actual tax rules themselves.
This article provides general information for U.S. authors, not tax advice.
This is part of the Complete Guide to Author Business Basics.
Deductible expenses reduce your taxable income, which directly reduces what you owe, but you can only claim deductions you can actually document. Reconstructing a year's worth of expenses from memory in April is both stressful and unreliable, and you'll likely miss legitimate deductions simply because you forgot about them or lost the receipt.
Open a separate account for your author business, even if it's just a second personal checking account rather than a formal business account. Route all royalty deposits and business expenses through it, which makes your business activity far easier to track and separates it cleanly from personal spending.
Categorize expenses as they happen, not in bulk later. A simple spreadsheet or a basic bookkeeping app works fine; the goal is monthly, not annual, categorization, since trying to remember what a charge from eight months ago was for rarely goes well.
Keep receipts and records, digital copies are fine, for anything you plan to deduct. Credit card and bank statements can serve as backup documentation, but itemized receipts are more reliable for anything questioned later.
Personal expenses that happen to occur alongside business activity generally aren't deductible. A vacation with some incidental writing time isn't a deductible research trip; a home office deduction requires a space used regularly and exclusively for business, not a corner of your living room you occasionally write in. Be honest about the business purpose of anything you plan to deduct, since this is an area where documentation and legitimate business purpose both matter if a deduction is ever questioned.
If you publish across multiple platforms (KDP, IngramSpark, audiobook platforms, direct sales), keep a simple running log of income by source and by month, in addition to whatever 1099s you eventually receive. This makes it much easier to reconcile what you've actually earned against the forms you receive, and to estimate quarterly tax payments accurately throughout the year rather than only once forms arrive.
Report income when you actually receive it, not necessarily when it was earned. If a royalty payment is issued in December but doesn't hit your account until January, it's generally counted as the following year's income, which matters for accurate quarterly tax planning near year-end.
Simple record-keeping throughout the year is something most authors can manage themselves. A tax professional becomes more valuable once your income grows substantially, your situation involves multiple income streams or foreign royalties, or you're considering a change in business structure. Even authors who eventually work with a professional benefit from having clean, organized records to hand over, rather than a shoebox of receipts.
Focus on Writing; Bring a Clean Record to Your Tax Professional
While Entrada doesn't provide tax advice, good record-keeping habits make working with a professional much easier when the time comes.
Common examples include editing, cover design, marketing, writing software, a qualifying home office, and research-related travel, though eligibility depends on your specific situation and proper documentation.
It's not strictly required, but it's strongly recommended. A separate account, even a simple second personal checking account, makes tracking business income and expenses far easier and cleaner.
Generally when you actually receive it, not when it was earned. A payment issued in December that doesn't arrive until January is typically counted as the following year's income.
Not necessarily. A simple, consistently maintained spreadsheet works fine for many authors, especially early on. The key is regular, monthly tracking rather than the sophistication of the tool.
