What is the difference between tax preparation and tax planning?

Tax preparation is the annual filing of your return. Tax planning is a year-round strategy to reduce the amount you owe through entity structure, timing, deductions, and retirement contributions, before the filing deadline arrives.

When should I start tax planning for my business?

Ideally, year-round. But if you haven't started, the best time is now. Planning done before December 31 can still produce significant savings. DWK Tax & Accounting works with clients throughout the year, not just at tax time.

Can tax planning reduce my quarterly estimated payments?

Yes. Proper planning helps ensure estimated payments are accurate, not overpaid, which is an interest-free loan to the IRS, and not underpaid, which triggers penalties. We calculate and review estimates every quarter.

Do you help with S-corporation or LLC tax strategy?

Yes. Entity structure is one of the highest-impact areas of small business tax planning. We evaluate whether your current structure is optimal and can guide you through an election or restructure when warranted.

Do you represent clients in IRS audits?

Yes. As a licensed CPA, David Korzeniowski can represent clients before the IRS and Illinois Department of Revenue for audits, notices, and correspondence.

Every business owner's tax situation is different. We take the time to understand your specific circumstances, goals, and growth plans, then build a strategy designed around your reality rather than a generic template.
