Your AI runs each step. You review.
01 Split from personal · create_business
One business book, fed by the account or card you actually get paid into. Bought business things on a personal card anyway? Your AI sweeps just those charges in as Owner’s Contribution, without dragging your groceries along.
Set up a book for my business. I get paid into Business Checking.
One book. Personal spending stays out of it.
02 Keep it current · bulk_categorize
Hand your AI a statement each month. It imports, categorizes against a freelancer-shaped chart of accounts, and flags what it is unsure about. Ten minutes of review instead of a lost Saturday.

Bank reconciliation
The books match the bank statement, every month.
Business Checking, June
The report totals. The judgment calls are theirs.
It does not e-file. You or your CPA enter the figures on your return.
Meals total onto line 24b in full. The 50% limit is applied on the form. The home office deduction, Form 8829, is not in the report.
Self-employment tax covers Social Security and Medicare. Federal and state income tax are calculated separately on top.
Mileage is a categorization discipline, not extra software. Standard mileage or actual costs is your CPA’s call.
Questions
The best fit tracks income and expenses on a real ledger, maps to Schedule C, and costs close to nothing, because a solo business should not carry enterprise software fees. LedgerMCP is free double-entry software where the AI you already use does the work.
You need books that reconcile to your bank account, and double-entry is how numbers stay provable. The good news is the rigor is the software’s job, not yours: your AI posts balanced entries, the database refuses unbalanced ones, and you just review. You get audit-proof books without learning debits and credits.
Yes. The built-in Schedule C report maps your categorized income and expenses to the form’s lines, including splitting travel and meals the way the form wants.
Ask your AI for a year-to-date P&L any time. For the mechanics and 2026 numbers, the quarterly estimated taxes guide walks through it, and the self-employment tax calculator gives you the SE piece.
For payments made in 2026, a client only has to file a 1099-NEC if they paid you $2,000 or more, and payment apps file a 1099-K only past $20,000 and 200 transactions. All of it is taxable either way, which makes your own books the record that matters.
Free: unlimited books, CSV import, categorization, reconciliation, every report including Schedule C. Live bank feeds start at $9/mo, and Growth at $39/mo includes a built-in AI assistant, so you do not even need a separate AI subscription. Either way the whole stack costs roughly one streaming service.
Connect your AI, hand it this month’s statement, and review what it flags.
