Is This Your Experience?

Most business owners dread tax season for a reason

Filing requires clean records, a real understanding of your entity structure, and year-round context that most preparers do not have.

The pain comes when someone sees your numbers for the first time in April and tries to make sense of them with no background and no time.

  • Incomplete or messy records at year-end
  • Surprise tax bill with no warning before it arrived
  • Missed deductions because no one asked the right questions all year
  • Unsure if your entity structure is actually saving you money
  • Filing on extension every year because the books were not ready

Tax returns are only as good as the process behind them.

We work from a complete picture of your financials, not a stack of documents handed over in March. Every classification and deduction is reviewed in the context of how your business actually operated that year.

Your owner personal return is prepared alongside the business return so the K-1 flows correctly and nothing falls through the gap between two separate preparers.

Why It Matters

What you get when your tax return is done right

Every deduction captured

We review the full picture of your business and apply every qualifying deduction: equipment, home office, vehicle use, retirement contributions, health insurance, and more.

Business and personal returns in sync

K-1 income flows cleanly from the business return to the owner's 1040. The same team handles both so nothing gets lost between two separate filings.

Filed on time

When books are maintained monthly, there is no scramble at year-end. Extensions are used only when strategically useful, not because we are not ready.

No surprises when you sign

We track your tax picture throughout the year. By filing time, your liability is expected, not a number you are seeing for the first time.

Clean, defensible records

Your return is prepared from books maintained all year, not reconstructed at year-end. Every number is supported and organized if it is ever questioned.

A debrief after filing

After the return is filed, we walk through what drove the liability and what to watch in the year ahead.

Owner Personal Return

K-1 income flows directly from business return
Prepared by the same team for full reconciliation
Owner-level deductions reviewed and applied

When paired with monthly accounting, returns are prepared from year-round maintained financials: faster turnaround, fewer questions, more confidence in every number.

Tax preparation is also available as a standalone service if your bookkeeping is handled elsewhere.

Typical Approach
Books managed by one person, taxes by another. Details get lost in translation
Tax preparer sees your numbers once a year with no context and no time
A return filed, then silence until next year
Eastlake CPA
Same team handles books and return. Every number is already known
Year-round visibility into your tax picture, with rough expectations before filing
Post-return debrief on what drove liability and what to adjust next year
The Integrated Advantage

When the same team handles your books and your taxes, everything is more accurate

Keeping bookkeeping and tax preparation separate creates a translation layer: context gets lost, deductions get missed, and year-end becomes a scramble to reconcile two sets of records.

When one team manages both, that gap disappears. Returns are faster, more accurate, and reflect decisions that can only be made by someone who knows your financials.

  • Returns prepared from books we maintained and trust
  • Business and owner personal returns filed together
  • Full deduction review because we know the financials
  • No year-end rush because we are already current
Who This Is For

For businesses that want more than a return that just gets filed

This service fits owners with real complexity: pass-through income, decisions that meaningfully affect the filing, and business and personal taxes that need to be thought about together.

Every engagement is relationship-based. The return reflects someone who actually knows your business.

1120S
Owners who want business and personal handled together, with owner compensation review included.
1065
Partnerships and multi-member LLCs that need accurate K-1 allocations across all partners.
1120
C-Corporations that need careful entity-level treatment and retained earnings review.
Sch. C
Sole proprietors and single-member LLCs who want a professional review, not DIY filing.

Also Worth Knowing

Standalone tax preparation is available. If you use monthly accounting with us, returns are faster and more thorough.
If you are switching preparers, we review your prior-year return during onboarding to carry forward balances correctly and catch anything that was missed.
We do not handle IRS resolution or audit representation. Our returns are organized and well-supported, but active dispute work is outside our scope.
