Small Business Tax Prep Checklist

Everything your accountant needs to file your business return, organized the way tax professionals actually want it. Save yourself hours of back-and-forth email.

Why this matters

The average business tax return goes through 3-5 rounds of 'we need one more thing' emails between client and preparer. Bringing the full package upfront eliminates that and often reduces the fee.

Missing documentation is the leading cause of extended tax returns. Extensions push the return to October, but they don't extend the tax payment deadline, interest and penalties still accrue.

A well-organized tax package protects you if the return is ever examined. Reconstructing years later is dramatically harder than delivering it clean the first time.

How to use it

Print the checklist and gather each item into a folder (physical or digital).
Reconcile bank and credit card statements before delivery, the preparer shouldn't be doing bookkeeping.
Include prior-year returns even if the same preparer filed them.
Deliver the complete package no later than mid-March for a timely April filing.
Ask upfront whether an extension makes sense, sometimes it produces a better outcome even when nothing is missing.
