Bookkeeping and accounting service with Tolonen Tax & Accounting is more than an administrative necessity. It is a profit center for your small business. Our monthly, quarterly, or annual financial statements will help you make informed business decisions and avoid costly financial mistakes. We will take the time to explain your financial statements and show you any accounting anomalies before they cause irreparable damage to your business.



If your business has 1-50 employees, and you need flexibility in your payroll processing without the big provider fees, we can help. From full service payroll, to spot-checking consultations, we can handle your vendor and employee tasks.

If you need full service payroll, we can provide paychecks to you and your employees on a weekly, biweekly, semi monthly, monthly, or annual basis. We prepare and file your federal and state compliance reports and help you pay your payroll taxes on time, every time.

We prepare W2s for your employees, and 1099s for your non-employee vendors. If the IRS, DES, or other tax authority sends threatening notices or audits your records, we’ve got your back there too.

If you own an S-corporation, the IRS expects you to pay wages. We will help you determine a reasonable salary and navigate the payroll complexities.


Sales Tax (TPT)

We will gather your sales data on a monthly basis and file your sales tax reports on your behalf, so that you can focus on what you do best – selling!


New Business Setup

Knowing how to set up your new business is a critical choice.  Should you be an LLC?  Should your LLC be taxed as an S-corporation, a C-corporation, a partnership, or sole proprietor?  Knowing where to begin is daunting, and a big hurdle to achieving your goals. We can help you set up your business the right way, minimize your tax liability, and maximize your asset protection.


Tax Authority Representation

If you get that dreaded letter from the IRS, state, or other tax authority, don’t ignore it! And don’t worry. But most importantly, don’t call a firm that advertises on late night TV. As part of your relationship with Tolonen Tax & Accounting, we will draft a written response to any tax notice, and represent you until the matter is resolved.
