In this guide, a business CPA lays out what to do, when to do it, and how each step connects so nothing slips through the cracks. Even if you skim, you’ll get a usable sequence to keep cash predictable and filings on time—plus links to services if you want help.

Choose an Entity, Register, and Get Your EIN
Start by protecting yourself and clarifying how profits are taxed. A business CPA helps you compare LLC, S-Corp, and C-Corp in plain English: liability shielding, payroll expectations, and how earnings reach your pocket. Once the path is chosen, file formation with your state, apply for the EIN, and draft an operating agreement or bylaws so roles, capital, and distributions are clear. A business CPA then maps registrations (state, city, sales tax, employer accounts) to your timeline. We also set naming conventions your bookkeeping will mirror—owners, classes of stock, wage vs. distribution. By front-loading these decisions with a business CPA, you reduce rework, avoid mismatched records, and make future elections (like S-Corp) easier. Capture every approval and certificate in a shared folder your team can access; clean documentation is the first gift you give future-you.

Build Your Bookkeeping System
Think of bookkeeping as your operating system. Your business CPA will design a right-sized chart of accounts (separating COGS from operating expenses), connect bank feeds, and set rules that auto-code recurring vendors. From there, standard operating procedures keep bookkeeping simple: weekly coding, receipt capture, invoice and bill cycles, and a month-end close with reconciliations. A business CPA also sets thresholds (e.g., purchases over $2,500 to fixed assets) so expenses vs. capitalization decisions are consistent. Choose cloud tools that integrate (accounting, bill pay, payroll, expense cards) and test the sync before going live. Good bookkeeping gives your business CPA and leadership team the same source of truth—so cash planning, pricing, and tax choices rest on current numbers, not guesses. The payoff is confidence: you’ll know what you earned, what you owe, and what you can invest next.
Sales Tax, Payroll, and Compliance Setup
Compliance is a calendar problem solved with systems. A business CPA inventories where you sell and employ staff, then registers the business for sales/use tax and payroll accounts in each applicable state. We configure your platform for tax rates, deposit frequencies, and new-hire reporting, and we wire those settings into bookkeeping so filings match the ledger. Payroll accuracy matters: wage types, benefits, and PTO rules should be documented and reviewed by a business CPA before first run. For sales tax, your bookkeeping needs SKU/location detail to file by jurisdiction. Then we build a shared compliance calendar—licenses, sales tax returns, payroll deposits, annual reports—so nothing slips. When your business CPA links each deadline to a report (e.g., sales by state, payroll summary), you replace scramble with routine, and late notices become rare.

Quarterly Estimated Taxes and Safe-Harbor Basics
Surprises happen when you skip estimates. A business CPA uses your live bookkeeping to project profit, then sets quarterly estimated tax payments using safe-harbor rules that minimize penalties. The process is simple: each quarter, we review results, adjust for seasonality, and recalibrate your payments. If you elect S-Corp, your business CPA will balance reasonable compensation with distributions and confirm withholdings align with cash flow. Clean bookkeeping makes these calls easy; messy books make them blind guesses. We also track credits and depreciation so your estimates aren’t inflated. The goal is predictability: you’ll know what’s due, when it’s due, and why. With a business CPA monitoring both federal and state exposure, you’ll avoid most penalty letters and keep capital available for hiring, inventory, and growth.
Monthly Financials: P&L, Balance Sheet, and Cash Flow
Great decisions come from rhythm. Each month, your business CPA closes the books and reviews three reports with you: Profit & Loss (how the month performed), Balance Sheet (what you own and owe), and Cash Flow (how money moved). We compare trends, margins, and runway, and we convert bookkeeping data into a simple narrative—what changed, where risk is rising, and what to do next. The P&L flags pricing and spend; the Balance Sheet reveals AR, debt, and inventory discipline; the Cash Flow statement shows if profits are turning into dollars in the bank. With a business CPA leading this loop, you’ll set targets, monitor KPIs, and decide with confidence. This is also where we prep for lenders or investors—clean numbers, consistent definitions, and a story that stands up to scrutiny.
Year-End Close, 1099s, and Tax Preparation
Year-end is smooth when the year was steady. Your business CPA reconciles all accounts, confirms fixed assets and depreciation, ties payroll reports to W-2 totals, and gathers vendor data for 1099s. We align your bookkeeping categories to the tax return, capture supporting schedules, and document elections. If adjustments are needed, we book them with notes so next year’s bookkeeping starts clean. Then we prepare and file returns, explaining what changed and what to expect next year (entity elections, credits, state exposure). The final step: a planning session where your business CPA turns the year’s lessons into next year’s budget and tax strategy. When bookkeeping and tax prep live in one integrated process, you get timely filings, fewer surprises, and a stronger financial story for partners and banks.
