What documents does my accountant need to do my small business taxes?

In most cases: a year-end profit and loss statement and balance sheet, bank and processor statements, categorized expenses with receipts for larger purchases, payroll reports and the W-2s and 1099s you issued, a list of equipment or assets bought or sold, last year's return, your entity paperwork, and any estimated tax payments you made. When your books are current, most of that comes straight out of your accounting file as reports.

How can I lower what my accountant charges at tax time?

Hand over clean, reconciled books. A large part of a tax preparer's time goes to organizing records that arrived as a pile rather than a report. When the income, expenses, payroll, and depreciation are already reconciled and categorized, your accountant spends the time on the return itself, which is usually where the cost comes down.

When should I start getting ready for tax season?

Reconcile through December once the year closes, pull your reports in January, and gather your short personal list of mileage, receipts, and standing documents alongside them. Handing the packet off well before the filing deadline gives your accountant time to ask questions while there is still time to answer them, instead of racing the clock in April.

Small-Business Tax Prep Checklist: What to Give Your Accountant

Tax season is smoother when your accountant opens a tidy folder instead of a shoebox. Most of the delay, and a good part of the bill, comes from the back and forth of tracking down records that should have been ready. The fix is a short checklist you can work through before you hand anything off.

Here is what a small business generally needs to assemble at tax time, grouped by category. Think of it as the packet that lets your accountant get to the actual return instead of spending billable hours organizing your year for you.

Income Records

Start with everything that came in. Your accountant needs the full picture of revenue, which is usually more than the deposits you remember off the top of your head.

Your year-end profit and loss statement and balance sheet
Bank and merchant-processor statements for every business account
Sales records from any platform you sell on, so online and in-person totals reconcile
Any 1099s you received for work you did

If reading those first two reports is not yet second nature, our walk-through of your P&L and balance sheet covers what each line is telling you.

Expense Records

Deductions live or die on documentation. The goal is a categorized expense record that ties back to statements and receipts, not a stack of guesses.

Categorized expenses for the year, straight from your books
Receipts for larger purchases, kept with the transaction
Vehicle mileage log if you claim business driving
Home-office details if that applies to you
Interest paid on business loans or credit lines

Payroll and Contractor Records

If you paid anyone this year, the people side of your books needs to be current and reconciled.

Payroll reports and the W-2s issued to employees
The 1099-NECs issued to contractors, with a W-9 on file for each
Payroll tax filings for the year

If you are not certain which workers belong on which form, we cover that in 1099 vs. W-2 classification in Florida. Getting it right during the year is what makes this row of the checklist a simple export.

Assets and Big Purchases

Equipment, vehicles, and other large purchases are handled differently from everyday expenses, so your accountant needs the details to depreciate them correctly.

A list of equipment or assets bought during the year, with dates and amounts
Anything you sold or retired, so it comes off the books
Your existing depreciation schedule, if you have one

Prior Returns and Business Documents

Context saves time. A few standing documents let your accountant pick up where last year left off.

Last year's business tax return
Your EIN and entity paperwork, and any change in structure this year
Estimated tax payments you made during the year, with dates and amounts

Current books turn five categories of records into one clean handoff.

What Your Bookkeeper Hands Over

Most of that checklist is not something you should be assembling by hand at all. When your books are kept current through the year, the income statement, the categorized expenses, the payroll and contractor reports, and the depreciation schedule are already sitting in your accounting file, reconciled and ready to export. What is left for you to gather is the short human list: mileage, a few receipts for big-ticket items, and the standing documents like last year's return and your entity paperwork.

That split is the whole point of keeping the books during the year rather than at the end of it. The cleaner the records your accountant receives, the less time they spend organizing and the more they spend on the return itself, which is usually where the bill goes down. If your books need work before they are ready to hand off, our post on a QuickBooks cleanup before tax season covers what that involves.

A Simple Timeline

You do not need to do all of this in April. Reconcile through December once the year closes, pull the reports in January, gather your short personal list alongside them, and hand the packet off with room to spare before the filing deadline. Working ahead is what turns tax season from a scramble into a handoff, and it gives your accountant time to ask questions while there is still time to answer them well.

The Bottom Line

A good tax-prep packet is five categories of records: income, expenses, payroll and contractors, assets, and your standing business documents. When your books are current, your bookkeeper produces most of it as reports, and you are left with a short list to gather yourself. Clean records shorten the work and usually the bill, and they give your accountant room to do the part you are actually paying for.

One note: this is a records checklist, not tax advice, and what applies to your specific return is a question for your CPA or enrolled agent. At Shea Business Solutions we keep monthly books tax-ready through the year and also handle small business tax preparation, so the records and the return line up in one place.
