How Accounting Firms Handle High-Volume 1099 Season Efficiently

Is your firm already dreading January?

You know the scene all too well. The holidays have come to an end, and you have hundreds (if not thousands) of Forms 10/99 due for clients in a matter of weeks. Pressures abound from all angles:

• Clients sending late or messy vendor data
• Tight IRS deadlines that never move
• A team that's already stretched thin

 

Here's the problem:

The vast majority of firms slog through 1099 season armed with spreadsheets, paper forms and piles of late nights. It works...most of the time.

One wrong TIN can cost more than the whole job is worth.

Here's the good news. Law firms that execute flawlessly during 10-99 season aren't working any harder than you are. They just have better systems in place. This manual shows you how.

Why 1099 Season Is So Tough On Firms

Filing season is short, fast and unforgiving. Most Forms 1099-NEC are due to the IRS and recipients on January 31. That leaves a firm only a few weeks to gather data, verify it, file and distribute copies.

And the rules keep changing.

Effective for payments made in 2026, the reporting threshold for codes 10 99- NEC and 1099-MISC will increase from $600 to $2,000. That will sound like less work. However, firms will need to revalidate every vendor at the higher threshold (along with explaining what happened to befuddled clients).

The Staffing Squeeze

Here's the thing most people don't talk about...

There's a shortage of accountants.  The Wall Street Journal reports that in two years over 300,000 U.S. accountants and auditors quit their jobs.  That's a 17% decrease.

Fewer people. Same number of forms. Something has to give.

The Penalty Trap

Filing errors can be costly during 10=99 season too.  The IRS will assess a penalty of up to $340 per late return, if your forms are received after August 1 (or not at all).  That gets expensive fast when you consider a few hundred clients.

That's why an increasing number of firms are transitioning to 1099 software for accounting firms that allows them to bulk import client information, e-file hundreds of 1099 forms with the IRS simultaneously, and automatically email recipient copies. Efficient 1099 filing software simplifies a tedious manual process into a streamlined workflow that your entire team can follow for each client.

Pretty cool, right?

 

What Makes High-Volume 1099 Filing Different?

Filing 10-99s for one client is simple. Filing them for 50 clients is an entirely different story.

Every client has different vendors, payer information and formatting errors. Some clients send a clean export from their accounting software. Other clients send a shoebox full of receipts and a "good luck" email.

Plus, e-filing just isn't optional for most businesses anymore. As of 2024, if your business has 10 or more information returns (combined), they're required to be filed electronically. That rule will catch most active firms, as it applies to nearly every client you serve.

 

The key difference is this:

A small business owner needs a place to file forms. An accounting firm needs a place to manage forms across dozens of clients simultaneously without losing their minds.

 

5x Ways Accounting Firms Handle 1099 Season Efficiently

Behaviors that differentiate cool companies from panicky ones.  Review them, select what applies to your firm and incorporate into your process this year.

Start Collecting W-9s In The Fall

Smart companies start sending out W-9 forms to client vendors long before January rolls around.

Why? Undeliverable names, addresses, and invalid TINs are the #1 reason you get a 1099.  If you discover them in October you have time to correct them.  If you discover them on January 29th... you don't.

Email clients a simple reminder in the fall requesting updated vendor lists, any missing W-9 forms and year-to-date payment totals.  One email can save your team days of legwork later.

Use 1099 Software Built For Accounting Firms

This is the biggest time saver of the lot.

Most standard tools are designed for one company. Firm-wide 1099 software allows you to track all clients through one dashboard. Easily toggle between payees in seconds and view which forms are completed and which still need attention.

Look for features like:

• Unlimited payers under one account
• Bulk e-filing with the IRS
• Print and mail options for recipient copies
• Easy corrections if something goes wrong

 

The right tool can pay for itself in the first week.

Import Data In Bulk (Not One By One)

Typing forms by hand is slow. It's also where most mistakes happen.

Rather than laboriously enter data, lean companies pull vendor data directly from a spreadsheet or CSV file. QuickBooks and Xero, among other accounting systems, can spit out vendor payment reports within minutes. Cleanup the file once, upload it, and you have hundreds of forms ready for review.

(There's that "keep it simple" motto in action again.)

Run TIN Matching Before You File

Want to avoid IRS notices in the spring?

Verify every name/TIN combination prior to printing the forms.  The IRS has a free TIN Matching service available through e-Services, and some 1099 programs have this verification built in.  A mismatch caught by you takes 2 minutes to correct.  A mismatch caught by the IRS results in a penalty notice and a very angry client.

Note: Keep track of all W-9 requests issued.  If a vendor declines to provide a TIN, your paper trail may help your client avoid penalties.

Build A Simple Deadline Calendar

Season lasts much longer than you might think.  There are multiple deadlines depending on what form you are filing.  Paper and electronic filing dates may differ.

Top firms build a shared calendar that shows:

• When client data is due to the firm
• When each form type is due to the IRS
• When recipient copies must go out

 

They then create internal deadlines one or two weeks ahead of the actual ones. The extra time allows wiggle room when inevitable surprises arise.

Win-win, right?

 

Bringing It All Together

Heavy workload 10nights season doesn't mean all-nighters and missed deadlines. Firms that have it down to a science repeat this easy process each year.

To quickly recap:

• Start collecting W-9s in the fall
• Use 1099 software that handles multiple clients
• Import data in bulk
• Check TINs before filing
• Set internal deadlines early
• Rinse and repeat

 

Fewer accountants and rising IRS penalties each year means the old fashioned way just won't work.  Find the right system for you now... and January will be a breeze.
