How to Organize Tax Documents for Your Accountant

Give your accountant one folder for the tax year with six parts: income records, expense receipts sorted by category, car records, records for anything big you bought or sold, the estimated tax payments you made, and last year's return. The IRS suggests keeping supporting documents in an orderly fashion and in a safe place, organized by year and type of income or expense. The checklist below shows what goes in each part.

What tax documents does an accountant need?

For a freelancer or small business, a tax organization worksheet usually comes down to this list:

Income: every Form 1099 you received, such as 1099-NEC, 1099-MISC or 1099-K, plus deposit records, invoices and receipt books.
Expenses: receipts, paid bills, canceled checks and card or bank statements, sorted by the expense lines of Schedule C.
Car: your mileage log, or your actual car expenses if you use that method.
Assets: purchase and sale records for equipment, vehicles or property the business owns.
Estimated tax: the dates and amounts of any estimated payments you made during the year.
Last year's return, which the IRS says helps when preparing future returns.

How do I organize tax documents?

The way the IRS suggests: by year, then by type of income or expense. Make one folder for the tax year with a section for each part of the list above, and use the same sections every year, so you and your accountant always know where to look. It works the same on paper or on a computer.

How do I prepare receipts for my accountant?

Sort them by category, total each category, and write the business reason on any receipt that does not show it. Match them against your statements so nothing is missing. If a receipt is lost, write a statement for it with our Missing Receipt Affidavit tool and include it with the statement line that shows the payment.

What is a tax document organizer?

Anything that keeps the year in fixed sections: an accordion file with labeled pockets, a set of computer folders, or a receipt app that sorts as you go. The tool matters less than using the same sections every year. In SparkReceipt, your accountant can be invited into your account and, in SparkReceipt's words, joins free.

What is the best way to store tax documents?

In a safe place, with a second copy somewhere else. Publication 583 says electronic records must meet the same requirements as paper ones and must be stored so they can be retrieved and reproduced in a legible form. Keep them until the period of limitations ends for the return they support, generally 3 years after you file and longer in some cases.

Questions people ask

What is a tax organization worksheet?

A checklist, often sent by an accountant before tax season, that lists the income, expenses and events of your year. If yours has not sent one, the list on this page covers the same ground for a freelancer or small business.

Who has to make estimated tax payments?

The IRS says individuals, including sole proprietors, generally have to make estimated tax payments if they expect to owe $1,000 or more when their return is filed. Give your accountant the dates and amounts of any you made.

Should I give my accountant original receipts?

Copies are usually enough. Keep the originals or your electronic records yourself, because you must keep records as long as needed to prove the income or deductions on your return.

Does my accountant need my bank statements?

Usually yes, for business accounts. The IRS lists account statements among the documents that support expenses, and they show the payments your receipts back up.

What if I am missing receipts?

Write a statement for each one with our Missing Receipt Affidavit tool, and include the card or bank statement line that shows the payment.

How long should I keep the documents after my accountant is done?

Generally 3 years after you file the return they support, 4 years for employment tax records, and longer in some cases. Our How Long to Keep Tax Records tool finds your date.
