Turn year-round bookkeeping into a tax return that’s accurate, audit-ready, and optimized
If you run a growing Boise business, tax preparation is rarely “just a form.” It’s a process that ties together your bookkeeping, payroll, owner compensation, deductions, and planning decisions you made (or didn’t make) throughout the year. The good news: with the right checklist—and a proactive CPA team—you can reduce last-minute scrambling, avoid common filing errors, and make smarter decisions long before the deadline.
Why “tax prep” feels hard for small businesses (and how to fix it)
For many business owners, the stress doesn’t come from the tax return itself—it comes from everything upstream: uncategorized transactions, missing receipts, unclear payroll reports, and “I’ll fix it later” bookkeeping. When your books are clean and consistent, tax preparation becomes a strategic review instead of a fire drill.
A practical goal for Boise owners: treat tax preparation as the final quality check on the year, not the only time you look closely at your numbers.
The Boise small business tax prep checklist (before you send anything to your CPA)
Use this checklist to make your CPA’s work faster and your return more accurate. It also reduces the “back-and-forth” that can delay filing.
1) Close the books (don’t just “reconcile enough”)
Make sure every bank and credit card account is reconciled through year-end. Review uncategorized expenses, duplicate entries, and personal charges run through the business. If you use QuickBooks Online or Xero, ensure your chart of accounts matches how your CPA will report your tax categories.
2) Confirm revenue is complete and recorded correctly
Provide year-end sales summaries from your POS, Stripe/PayPal, Shopify/Amazon, or invoicing system—then confirm deposits match what’s recorded in the books. This is a common mismatch area for service businesses (especially when client prepayments, retainers, or refunds are involved).
3) Gather payroll and contractor documents
Payroll touches federal, state, and local compliance. Pull your year-end payroll reports, quarterly filings, and benefits deductions (health insurance, retirement, HSA, etc.). If you paid contractors, compile totals by vendor and confirm you have updated W-9s so your team can prepare any required 1099s.
4) Document big purchases, equipment, and vehicles
Create a list of assets purchased during the year (computers, furniture, machinery, software with setup costs, and anything that feels “capital”). For vehicles, keep a mileage log and note the business purpose of trips. Mileage rates and deduction options can change year to year, so your CPA needs good records—not guesses. The IRS has announced the 2026 business standard mileage rate increase to 72.5 cents/mile starting January 1, 2026. (apnews.com)
5) Clean up owner payments (this is where returns get messy)
Boise business owners often mix draws, reimbursements, payroll, and personal expenses. Before tax prep, identify:
This step is especially important for S-corporations and partnerships where “what you call it” affects taxes.
6) Bring prior-year returns and any IRS/state notices
If you received letters from the IRS or Idaho State Tax Commission (even if you think you handled them), provide copies. Notices often relate to mismatched reporting and can be easier to resolve quickly when your CPA has the full story.
A quick table: What to prepare vs. what your CPA does
| Task | You (business owner) | CPA team |
|---|---|---|
| Bookkeeping close & reconciliations | Confirm accounts are reconciled; provide missing info | Review for tax-ready categorization and adjustments |
| Payroll & contractor reporting | Provide payroll summaries, benefit info, W-9s | Verify compliance; prepare/coordinate filing needs |
| Deductions & substantiation | Provide receipts, mileage logs, business purpose notes | Apply tax rules, elections, depreciation methods |
| Tax return preparation & filing | Review for reasonableness; approve e-file | Prepare and file; advise on payment/estimates |

Note: Your exact impact depends on entity type (sole prop, partnership, S-corp, C-corp), payroll structure, and deductions.
Step-by-step: A “no-panic” tax prep timeline for small businesses
Step 1: Set a records deadline (and stick to it)
Pick a date to stop changing last year’s numbers unless it’s truly necessary. Constant revisions create confusion and increase the risk of inconsistencies across payroll, bookkeeping, and tax filings.
Step 2: Build a “tax binder” folder (digital is fine)
One shared folder with consistent naming saves hours. Include bank statements, credit card statements, loan statements, payroll reports, and any notices. Add a simple “Questions for CPA” note you can update as things pop up.
Step 3: Schedule tax planning before filing season hits peak demand
Tax preparation reports the past. Tax planning improves the future. If you’re hiring, changing pricing, buying equipment, or considering a new entity structure, planning conversations are where you can often save more than “last-minute deductions.”

FAQ: Tax preparation for Boise small businesses
What should I send my CPA first to speed up tax preparation?
Start with reconciled financials (P&L and balance sheet), payroll summaries, a list of big purchases/asset acquisitions, and any tax notices. Clean, reconciled books reduce follow-up questions and help your CPA focus on strategy.
Is it okay to file an extension?
Often, yes—extensions can provide time to finalize accurate reporting. But an extension to file is not an extension to pay. Your CPA can help estimate payments to avoid penalties and interest.
I’m in Boise—do Idaho tax changes affect my planning?
They can. For example, Idaho reduced the individual income tax rate to 5.3% effective January 1, 2025, which can affect withholding and projections. (paylocity.com)
When should I consider tax planning (not just tax prep)?
If you’re growing, hiring, changing entity structure, buying equipment, or thinking about selling your business, tax planning can materially affect your after-tax outcome. It’s most effective before the year ends or before major decisions are finalized.
Can my CPA help if I’m considering buying or selling a business?
Yes. Transaction structure, due diligence, and tax impact often matter as much as the purchase price. Having CPA guidance early can protect you from costly surprises.
