How Bookkeepers and Tax Preparers Can Raise Their Rates
Bookkeepers and tax preparers spend their working lives explaining numbers to clients, yet many keep their own fees unchanged for years, even though producer price data show the market for their services has moved, and an annual engagement letter gives them a natural, expected moment to change.
At a glance
- A break-even fee increase is one where the extra margin on every remaining client covers the clients who leave; for a tax practice with a 60% margin per return, a 10% increase still breaks even if one client in seven goes elsewhere.
- The Bureau of Labor Statistics producer price index for tax preparation and planning rose about 23.6% in the five years to August 2026, close to the 22.4% rise in consumer prices overall, so a preparer still charging 2021 fees has fallen behind both the market and inflation.
- Clients judge a renewal-time increase that passes on rising costs as fair: in household surveys published in the American Economic Review, 75% of respondents accepted a landlord raising rent at renewal to cover higher costs.
- Federal rules for tax practitioners prohibit unconscionable fees and, with narrow exceptions, contingent fees, so a fee increase in this trade should be built on time, complexity and scope, never on the size of a refund.
Part 1 | The market for tax and accounting work has already moved
Many preparers and bookkeepers set their fees when they opened and have adjusted them only when a client complained about something else, and the inner voice before every season sounds like My clients are small businesses; they can't afford more. The producer price data, which track what businesses actually receive for their services, tell a different story. The Bureau of Labor Statistics index for tax preparation and planning rose about 23.6% between August 2021 and August 2026 and 5.8% in the latest year, and the index for offices of certified public accountants rose about 23.5% over the same five years.
A practice whose fees match 2021 is therefore charging about 18% less in real terms than it did then, while the software subscriptions, e-filing costs and staff wages that sit behind each return have not stood still.
Part 2 | The engagement letter is the natural moment to change fees
Tax and bookkeeping work renews on a calendar, which gives this trade an advantage most service businesses lack. Clients expect a new engagement letter or organizer each year, and the fairness research suggests renewal is when an increase reads as most reasonable: in the American Economic Review surveys, 75% of 151 respondents judged it acceptable for a landlord to raise rent at renewal to cover higher costs, and 79% accepted a grocer passing on a higher wholesale cost. A later study in the Journal of Consumer Research found that consumers tend to overlook much of what it costs to run a business, so a client who hears no reason for the increase tends to assume it went to profit.
For bookkeepers, the structure of the fee matters as much as the level. A study published in the Journal of Marketing Research found that consumers often prefer a flat rate even when paying per use would cost them less, and that this flat-rate preference did not significantly increase customer churn, while a bias toward pay-per-use plans largely did. A monthly package priced by transaction volume and number of accounts may feel safer to a small business client than an hourly bill that changes every month.
The rules of the trade set firm limits. Treasury Department Circular 230, which governs practice before the IRS, states that a practitioner may not charge an unconscionable fee and, apart from narrow exceptions such as certain IRS examinations and judicial proceedings, may not charge a contingent fee, so fees for an original return should reflect forms, complexity and time rather than the refund. General information, not legal/tax/financial advice; talk to a licensed professional about your situation.
Part 3 | Six steps for raising rates in a tax or bookkeeping practice
- Price by scope, not by habit. Set a base fee for a return and add defined amounts for each Schedule C, rental, K-1 or state return, so complex returns stop subsidizing simple ones.
- Announce with the engagement letter or organizer, ideally in November or December, before clients start gathering documents.
- Give one plain reason, such as higher software, e-filing and staff costs since your last change.
- Set a document deadline and a late fee, for example an added charge or an automatic extension for documents received after a date you choose, so the March rush pays for itself.
- Move bookkeeping clients to monthly packages with volume tiers and a separate rate for catch-up or cleanup work.
- Review your lowest-margin clients, and decide whether the new fee or a referral elsewhere fits each one.
The letter can say: "For the 2026 tax year, our base fee for an individual return with one state is [price], with Schedule C and rental schedules priced as listed below. Our software, e-filing and staffing costs have risen since our last change, and this keeps our turnaround at ten business days for documents received by March 1. Documents received after March 15 will be filed on extension."
| Individual returns per season (Assumption) | 250 |
|---|---|
| Current average fee (Assumption) | $400 |
| Cost per return (preparer time, software, e-filing) (Assumption) | $160 |
| Margin per return (Calculated ($240 ÷ $400)) | 60% |
| Season margin before the increase (Calculated (250 × $240)) | $60,000 |
| New average fee after a 10% increase (Calculated) | $440 |
| Break-even share of clients who could leave (Calculated (10% ÷ 70%)) | 14.3% |
| Season margin if 4% of clients leave (Calculated (240 × $280)) | $67,200 |
| Extra margin per season (Calculated ($67,200 − $60,000)) | $7,200 |
Illustrative example; replace every assumption with your own numbers.
How you compare
- Against the market: if your fees are unchanged since 2021, the producer price index for tax preparation suggests similar services now cost about 24% more.
- Against your margin: add up the preparer time, software and e-filing cost behind an average return, divide by the fee and subtract from 100%.
- Against yourself: note returns filed, clients retained and average fee this season, then compare the same three numbers after the change.
Questions to ask this week
When did we last change fees, and what has risen since? List software, e-filing, staff pay and insurance with old and new costs.
Which clients take the most time for the fee they pay? Sort last season's returns by hours per dollar.
When do engagement letters go out this year? Choose the date and put the new fee schedule in the letter.
Do our bookkeeping clients pay a predictable monthly amount? If not, draft three tiers by volume.
Calculate your margin on an average return this week, run the break-even formula for a 5%, 8% and 10% increase, and write the new fee schedule into this year's engagement letter.
About this research: This article draws on Bureau of Labor Statistics producer and consumer price indexes via FRED, household fairness surveys in the American Economic Review, research on price perceptions in the Journal of Consumer Research and on tariff choice in the Journal of Marketing Research, and Treasury Department Circular 230. The fairness and tariff studies did not involve tax clients. The worked example is illustrative.
