Your business income has changed significantly.

02

You are forming, buying, selling, or restructuring a business.

03

You are hiring, selling, or operating in additional states.

04

You receive K-1, rental, investment, or equity-related income.

You are preparing for a major purchase, sale, or transition.

Frequently asked questions

Tax preparation and planning, explained

What is the difference between tax preparation and tax planning?

Tax preparation reports and files what happened during the completed year. Tax planning looks forward, using projections and known facts to evaluate decisions while there may still be time to act. Many clients benefit from having both handled within one coordinated relationship.

Can you prepare both my business and personal returns?

Yes, when included in the engagement scope. Coordinating the business and personal filings can be especially useful for owners of pass-through entities, clients receiving K-1s, and households with multiple sources of income.

Do you work with multi-state clients?

Yes. We serve clients in Oregon and California, support Washington matters, and coordinate applicable federal and state filings for clients nationwide. The required filings and scope depend on where you live, work, own property, hire, or conduct business.

How often should tax planning happen?

The right cadence depends on the pace of change. Some situations may require an annual year-end review, while business owners and clients with significant changes may benefit from quarterly or event-driven planning.

How are tax-service fees determined?

Fees depend on the number and type of returns, entities, states, quality of records, transaction complexity, deadlines, and level of planning support. We recommend a scope after learning about your situation.

What happens after I request a consultation?

We begin by understanding your entities, filing history, states, records, upcoming decisions, and goals. If the engagement is a fit, we provide a clear scope, organize the information request, prepare and review the work, and identify appropriate next steps.
