Side Ledger: 1099 Tax Tracker

Know what you owe the IRS before the bill arrives.

SideLedger keeps a running estimate of your federal and state taxes while you earn. Log a payout, snap a receipt, add your miles — the number on your dashboard updates on the spot, next to a countdown to the quarterly deadline.

Built for rideshare and delivery drivers, online sellers, creators, and freelancers — anyone with 1099 income and nobody withholding taxes for them.

THE NUMBER THAT MATTERS, ALWAYS IN SIGHT
• Estimated tax owed on your dashboard and on a home screen widget
• A countdown to every IRS quarterly deadline, with reminders before each one
• A step-by-step breakdown of the estimate: self-employment tax, income tax, QBI deduction
• IRS 2026 rates built in — new tax-year numbers arrive without waiting for an app update

LOG IT IN THREE SECONDS
• Income, expenses, and mileage, each in about three taps
• Snap a receipt and the total, date, and merchant are read right on your phone — offline
• Every expense filed under a Schedule C category
• Miles shown as dollars deducted, because that is what they are worth

KEEP MORE OF WHAT YOU EARN
• A deduction checklist matched to your line of work, from phone bills to parking
• Safe harbor mode to help you plan around underpayment penalties
• Mark each quarterly payment as paid and watch the number come down
• Export a clean CSV and a one-page PDF summary for your accountant

YOUR BOOKS STAY YOURS
No bank login. No account to create. Your income and receipts live on your device, the estimator works in airplane mode, and a backup is a file you keep wherever you keep files — never with us.

Multiple hustles with one combined estimate, unlimited entries and receipt scans, the full deduction checklist, safe harbor mode, CSV and PDF export — everything in one app.

Estimates are for planning purposes only. Not tax, legal, or financial advice. Consult a tax professional.
