How is employer unemployment tax calculated for Washington ESD?
I'm starting a small business in Washington and trying to understand how the employer unemployment tax works. I know I have to pay into the system but I'm confused about how Washington ESD calculates the rate. Is it based on payroll amount, number of employees, or something else? Also heard there's something called an 'experience rating' that affects the rate but not sure how that works for new employers. Any business owners here who can explain this?

The Washington ESD employer tax rate has two parts - the experience rating and the social cost factor. For new employers, you start with a standard rate that's set each year. The experience rating is based on your history of layoffs and claims filed by your former employees. More claims = higher rate.

•So as a new business I won't have any experience rating history yet? What rate would I start at?

•Correct, new employers get assigned the 'new employer rate' which is usually around 2.7% but it changes annually. You'll get your official rate notice from Washington ESD once you register.

yeah its calculated on your total payroll up to the wage base. i think the wage base for 2025 is like $71,000 per employee so you only pay the tax on the first $71k each person earns

•That's helpful! So if I have an employee making $80,000, I only pay the unemployment tax on $71,000 of their wages?

•exactly! once they hit that wage base amount you stop paying unemployment tax on their wages for the rest of the year

The experience rating system is actually pretty complex. Washington ESD looks at the ratio of benefits charged to your account versus your total payroll over a specific period. If you have a lot of former employees collecting unemployment, your rate goes up. If you have stable employment with few claims, your rate can go down over time.

•This is why some employers try to fight unemployment claims even when they're legitimate. Higher claims = higher tax rates.

•True, but Washington ESD has appeal processes for employers too. If you think a claim was filed incorrectly, you can contest it through their system.

•Good to know there's an appeal option. How long does that process usually take?

I've been dealing with Washington ESD employer services for years and honestly their phone system is terrible when you need to ask questions about your tax rate or get clarification on charges. I found this service called Claimyr that helps you actually get through to a live person at Washington ESD - check out claimyr.com and they have a demo video at https://youtu.be/7DieNd3C7zQ. Made my life so much easier when I needed to dispute some charges on my account.

•Never heard of that service before. Does it actually work for employer-side issues or just claimant stuff?

•Works for both! I used it to get through to employer services to clarify some benefit charges that didn't look right on my quarterly statement.

Don't forget about the administrative contingency fund surcharge too. That's an additional percentage on top of your regular rate. It's usually small but it adds up.

•How many different fees are there?? This is getting complicated.

•Just the experience rate, social cost factor, and administrative surcharge. Washington ESD combines them all into one rate on your quarterly statement so you don't have to calculate each piece separately.

The whole system is designed to make employers subsidize the unemployment benefits. More layoffs from your company = you pay more. It's supposed to incentivize keeping people employed but sometimes economic conditions force layoffs regardless.

•That's the point though - companies that create more unemployment claims should pay more into the system.

•I get the logic but it can penalize seasonal businesses or industries that naturally have more turnover through no fault of the employer.

OP, make sure you register with Washington ESD as soon as you hire your first employee. There are penalties for late registration and you want to start building your experience rating history right away.

•What's the deadline for registering? Is it immediately when I hire someone or do I have some time?
0 coins
Connor Byrne
•You're supposed to register within 30 days of becoming liable for unemployment tax, which is basically when you hire your first employee in Washington.

I'm a CPA and work with small businesses on this stuff regularly. One thing to note is that Washington has some of the highest unemployment tax rates in the country, but the wage base is also higher than many states. Your effective rate depends on your specific industry and experience rating.

Sofia Perez
•Are there any industries that typically have higher or lower rates?
0 coins
Keisha Williams
•Construction and seasonal industries tend to have higher rates due to more layoffs. Professional services and healthcare often have lower rates due to more stable employment.

Sofia Perez
•That's encouraging! How long did it take for your rate to start decreasing?

•think it was after the third or fourth year when i had enough history for washington esd to calculate a proper experience rating

Just a heads up that the rates and wage base change every year. Washington ESD publishes the new rates in December for the following year. Make sure you're using current numbers for your payroll calculations.

•Yes, it's on the Washington ESD website under employer resources. They also mail rate notices to registered employers.

The experience rating calculation period is usually the first four of the last five completed calendar quarters. So they're not using your most recent quarter's data, which can be confusing when you're trying to figure out why your rate changed.

Sofia Perez
•That's oddly specific. Why not just use the most recent data?

•It allows time for all claims to be processed and finalized. Unemployment claims can take time to resolve so they need that lag period for accurate calculations.

MAKE SURE YOU KEEP GOOD RECORDS!! Washington ESD can audit your payroll records and if you can't prove wages were paid correctly you could face penalties and interest charges. I learned this the hard way.

•What kind of records do they want to see during an audit?

•Payroll registers, employee time records, tax returns, anything that shows wages paid and taxes withheld. They go back several years sometimes.

I tried calling Washington ESD employer services last month to clarify some charges and spent literally 3 hours on hold. Finally gave up. Somebody mentioned Claimyr earlier - has anyone actually used that to get through to employer services?

For new employers, you might also want to look into whether you qualify for any rate reductions or incentives. Some industries or regions have special programs that can lower your initial rate.

Sofia Perez
•Really? What kind of incentives are available?

Isabella Silva
•There are sometimes programs for hiring veterans, ex-offenders, or long-term unemployed workers. Check with Washington ESD or your local WorkSource office.

don't forget you also have to pay federal unemployment tax (FUTA) on top of the state unemployment tax. that's a separate 6% on the first $7000 of wages but you get a credit for paying state unemployment tax so its usually only 0.6%

Sofia Perez
•So I'm paying both state and federal unemployment taxes? That's going to add up quickly.

Ravi Choudhury
•yeah but the federal part is pretty small compared to washington state. the state tax is where the real cost is

One more thing - if you have employees who work in multiple places or have remote workers, make sure you understand which state's unemployment system applies. It's not always where your business is located.

Sofia Perez
•I was planning to hire some remote workers in other states. How does that work?

•It depends on where they're physically working and the specific arrangements. You might need to register in multiple states. Definitely consult with a payroll service or accountant for multi-state situations.

Washington ESD also has online calculators and resources for employers. Their website has improved a lot over the years and you can do most of your quarterly reporting online now.

Just remember that unemployment tax is just one of many payroll taxes you'll be dealing with as an employer. Factor in Social Security, Medicare, state income tax withholding, and workers comp when budgeting for labor costs.

Final tip: Washington ESD employers have to report new hires within 20 days. It's part of the child support enforcement program but it's required for all employers regardless of whether your employees have child support obligations.
