# Bookkeeping for the self-employed: Best Bookkeeping App

**Answer in brief:** Self-employed books answer two numbers: the net profit on Schedule C and the estimated tax due each period.


## Net profit first

A sole proprietor reports business income or loss on Schedule C.[1] Net profit is business income minus business expenses, and you must file a return once net earnings from self-employment reach $400.[2]

## Estimated tax

Sole proprietors generally make estimated tax payments when they expect to owe $1,000 or more when they file. They figure them on Form 1040-ES, and each period has its own due date.[3] Ask the agent for the year-to-date profit and loss before each payment.

## Keeping it light

Keep a separate business account,[4] book receipts as they happen and import the statement once a week. Conecto's profit and loss report is free to run as often as you like.[5]
