Bookkeeping and taxes from one firm, or two?
How one firm for both compares with a separate bookkeeper and tax preparer, and how to tell which one suits your business.
Who handles bookkeeping and business tax filing together?
Total BizSolutions LLC, an accounting firm in Trumbull, Connecticut, keeps the monthly books and prepares the business and personal tax returns for small businesses in Connecticut and throughout the United States. The same firm runs payroll and handles estimated tax payments and sales tax filing, so the return is prepared from books it keeps and reconciles. The owner, Dave Salerno, has more than 30 years of experience. Call (267) 710-6742, Monday to Friday, 9am to 5pm.
What changes when one firm does both
With two firms, the bookkeeper closes the year and sends a set of reports to whoever prepares the return. The preparer meets those books for the first time in tax season. Any question about a number goes back to the bookkeeper, usually through you.
With one firm, whoever prepares the return can open the reconciliations, see why a transaction was coded the way it was, and correct the books before the return goes out. The return and the books are built to agree because they sit with the same firm.
Plenty of businesses run well with a bookkeeper and a separate tax preparer who talk to each other. The real difference is how much of the year-end work lands on you as the go-between.
Separate bookkeeper and tax preparer vs one firm
| Question | Separate bookkeeper and tax preparer | One firm for both |
|---|---|---|
| Who keeps the books | Your bookkeeper, each month | The firm, each month |
| Who prepares the return | A separate preparer, once a year | The same firm, from the books it keeps |
| Year-end handoff | Reports sent from one office to the other, with questions routed through you | No handoff between offices: the books and the return sit with one firm |
| Quarterly estimates | Worked out by the preparer, from whatever numbers they are sent | Can be worked out from this year's books |
| Payroll and sales tax | Can sit with a third provider or a payroll app | Handled by the same firm that keeps the books |
| A tax notice arrives | You collect records from one office and send them to the other | The records behind the return sit with the same firm |
| People to call | Two | One |
Who one firm suits, and who it does not
Best for
- Owners who want one call when a number looks wrong, whether it sits in the books or on the return
- Business owners who file both a business return and a personal return
- Businesses with payroll or sales tax to file, where the filings and the books have to agree
- Owners who are behind and want catch-up bookkeeping first, then a return prepared from the cleaned-up books
Not the best fit
- Owners whose bookkeeper and tax preparer already work well together. Changing a setup that works costs time and buys little.
- Anyone who needs someone to represent them before the IRS, in an audit, a collection case or an appeal. The IRS reserves full representation rights for specific credentials, such as CPAs and attorneys, so bring in a representative who holds one, whichever setup you choose.
If you do bring in a representative, the books and records they ask for are the part a bookkeeping firm can keep ready.
How to decide
Count the handoffs
List every time this year you forwarded a question, a report or a statement between your bookkeeper and your tax preparer. A long list is time one firm would save you.
Check what the return starts from
If your return is prepared from reconciled monthly books, the current setup is doing its job. If it starts each spring from a pile of bank statements, the books are not feeding the return.
Look at the filings in between
Payroll, quarterly estimates and sales tax all happen during the year. Ask who checks that each one agrees with the books. If the answer is nobody, that is a gap worth closing.
Decide whether you need representation
If you expect an IRS audit, a collection case or an appeal and want someone to represent you, plan for a representative with the credentials the IRS requires, whichever setup you pick for the books and the return.
How it works with us
- 1
A short first call
We talk about how the business runs, what state the books are in and whether catch-up work is needed first.

Documents through the portal
Statements and paperwork come in through a secure client portal, so the work runs the same for a business in Trumbull or one three states away.

Payroll, estimates and sales tax
Payroll runs with its tax filings, and W-2s and 1099s go out at year end. Estimated tax payments and sales tax filing sit with the same firm that keeps the books.

Questions about one firm for books and taxes
Is one firm for bookkeeping and taxes cheaper?
Compare the total you pay both providers now, plus the hours you spend passing questions between them. Monthly work with us is priced starting at $500/month. Ask about your return on the first call.
Can you take over my books partway through the year?
Yes. If the books are behind, catch-up bookkeeping comes first as its own job, and the monthly rhythm starts once you are current. The return is then prepared from the caught-up books.
Do you prepare my personal return as well as the business one?
Yes. For most business owners the two belong together, because a personal return that ignores what happened in the business is guessing.
Do I need to be in Connecticut?
No. The office is in Trumbull, Connecticut, and we work with small businesses throughout the United States. Documents move through a secure client portal.
What happens if I get an IRS notice?
Send it over. We read it, tell you in plain terms what it asks for, and pull together the records it names. Because we keep the books, most of those records are with us already.
