A Complete Tax Return Checklist to Send to Your Clients

tax return checklist for clients

Though each client's financial situation is unique, there are several common items you’ll need from each of them to prepare a tax return. 

Rather than starting from scratch each time, you can use a checklist that covers most situations. Below is a template you can customize for your own practice.

A Tax Return Checklist to Send to Your Clients

This tax return checklist is appropriate for a federal tax return. You should also consider adding state-specific questions. Note that the list below covers the most common items but won’t address every situation.

You can also access the checklist here (note: view only - make a copy or download to edit this document).

Dear Client,

We are very excited to be preparing your tax return this year. In order to smooth the data collection process, we have created a checklist of information we will need to complete your return. Please note that not all items will apply to everyone.

We will need to receive your documentation by April 1st in order to complete your return by April 15th. If we receive your information after this date, we will file an extension for your return and reach out to you after the April 15th deadline to complete the return.

If you have any questions, please contact me by email or phone.

When Should You Send Clients This Checklist?

As the tax season approaches, many accountants begin to wonder when they should ask their clients for their tax information. While there is no hard and fast rule, it is generally advisable to start collecting tax documents from clients at least a month before the tax return is due. 

This gives accountants enough time to review the information and ensure everything is in order. It also allows them to catch any errors or discrepancies that may have been made on the tax forms. 

Asking for tax information too late can often lead to rushed work and errors on the return. By starting the process early, accountants can help ensure that their client's tax returns are accurate and filed on time.

Some accountants choose to send the checklist in early January. Doing so allows clients to have the checklist in hand as they receive documents in January.

What Other Information Should You Send with the Checklist?

When sending a checklist to your clients, you should also include several other pieces of information. You should let the clients know how you plan to accept their documentation - whether by mail, in person, or digitally. If your clients are submitting their information digitally, you should ensure you have a secure method of accepting and storing their files.

The checklist should also include your deadlines for accepting information and meeting the tax filing deadlines. Most accountants set a cutoff date of April 1st for receiving the client’s paperwork and completing the return by April 15th.
