Know what you owe
before the quarter closes.
Log income, expenses and mileage as they happen. 1099 Assistant keeps a running federal and state estimate, so the number you set aside is one you worked out in March — not one you discovered in April.

How it works
Three things, then it runs itself
There is no setup wizard and no chart of accounts to design. Tell it where you live, then log work as it comes in.
Pick your state
That is the whole of setup. It sets your tax tables and your timezone, so a Friday-night expense stays on Friday.
Log as you go
Payments in, expenses out, miles driven. Set up the ones that repeat — a monthly retainer, a software subscription — and they post themselves.
Check the number
Your estimate moves with every entry. At quarter end, export the workbook or hand your accountant read-only access.
Features
Enough to file with, nothing you won't use
Built around the three numbers a contractor is actually judged on: what came in, what was deductible, and what the IRS wants for it.
Tax estimates that update
Self-employment tax, federal brackets, your state's rate and the child tax credit, recalculated on every entry. The working is shown line by line, so you can see why the number changed.
Income and deductions
Log payments by client and expenses against IRS categories. Attach a receipt to any entry — stored encrypted, so a copy of the database is not a copy of your paperwork.
Mileage at the federal rate
Business trips at $0.70 a mile for 2025. Log the route once and it becomes a deduction with a record behind it, which is the part that matters if anyone asks.
Coverage
All 50 states, plus DC
State income tax is applied automatically from your profile — a flat rate where your state uses one, full brackets where it doesn't, and nothing at all in the nine states that don't tax income.

Questions
Before you sign up
Is this tax advice?
No. 1099 Assistant produces an estimate from the figures you enter and the published federal and state tables. It does not know about your other income, a spouse's job, credits you may qualify for, or anything else on your return. Treat the number as a planning figure for what to set aside, and have a preparer file for you.
Do I have to connect a bank account?
No, and there is no option to. Nothing here reads your accounts or your card statements. You enter the income and expenses you want tracked, which means the only financial data on our servers is what you chose to put there.
What happens to my data if I stop paying?
Your account drops to the free plan. Nothing is deleted — your existing entries stay readable and exportable, you just go back to the monthly limits on adding new ones. You can export the whole thing to Excel before or after downgrading.
Can my accountant see my figures without my password?
Yes, that is the intended way to do it. You invite them by email and they get a read-only view of your entries and reports under their own sign-in. They cannot change anything, and you can revoke access at any time. You are notified when they open your books.
How is my account protected?
Passwords are checked against known breach corpora at sign-up and never stored in a readable form. You can add two-factor authentication from an authenticator app, with recovery codes and an email fallback if you lose the phone.
You can also see every device signed in and sign any of them out remotely, set an idle screen lock behind a PIN, and require the app to re-authenticate. Uploaded receipts are encrypted at rest.
Does it work on a phone?
There is an Android app, and the website installs to a home screen on both platforms. Entries made offline are queued on the device and sync once you are back on a connection, so logging a trip in a parking garage works.
Which tax year does it use?
The current default is 2025, using the figures published in IRS Rev. Proc. 2024-40. Entries carry their own date, so income from a previous year is calculated against that year's tables — useful given most people are still filing the last one well into the next.
