SECTION 2

Get Your Year-End Payroll and Taxes Ready

Payroll and taxes often feel like the most intimidating part of Q4, mostly because the stakes feel high and the language is dense. But that doesn't have to be the case. Here’s everything you actually need to know to nail your end-of-year money moves.

Before you run your last payrolls of the year, take a pass through employee records. Wrong addresses mean wrong W-2s. Outdated bank info means delayed pay. A five-minute audit now can save a big headache in January.

While the responsibility often falls on you, there are moments your employees need to take action before the new year. That’s why we created a simplified version of these reminders that you can share directly with employees.

Take Care of Your People

Closing out the year well isn't only about compliance. It's about being the kind of employer your team wants to keep working for into the new year.

This isn’t a simple “to offer or not to offer” decision. You’ll need to choose how to structure your end-of-year pay overall: lump sum vs. recurring, cash flow planning, and morale impacts are all important factors.

Whatever you decide on bonuses, benefits, or PTO, how you communicate it matters as much as the decision itself. Make sure you give those moments of communication the attention they deserve to avoid misunderstandings or frustration before heading into the holiday season.
