What a Tax Preparer Costs in St. Louis

Revised August 20, 2026

Imagine it’s the first Saturday in February and the folder has been sitting on your kitchen table since New Year’s. A W-2. A 1099 from the weekend work. The mortgage interest statement. An envelope of receipts you keep meaning to sort. You finally call around, and an office in Affton quotes you $175, while one off Manchester Road in Kirkwood says it will land closer to $450 once they see the Illinois return.

Neither of them is trying to take you. That spread is normal, and it has almost nothing to do with honesty. It has to do with who is signing the return, which forms your situation actually requires, and how each office decided to price its work in the first place.

What follows is what tax help really costs around this metro, what you are buying at each rung of the ladder, and where the padding hides — with a source and a year attached to every number, because fee figures go stale fast. This is general information, not advice about your particular return.

How much do most tax preparers charge?

Most people pay between roughly $185 and $300 for a straightforward individual return, and the number tracks the preparer’s credential more than anything else. The 2025 National Fee Survey from the National Association of Tax Professionals, reported by Accounting Today on December 23, 2025, put the average fee for a base Form 1040 at $280 for CPAs, $228 for enrolled agents, and about $185 for preparers holding no credential.

Two more numbers from that same survey are worth having before you dial. The average base 1040 ran $185 in communities under 10,000 people and $233 in communities of 50,000 and up — so a metro-area quote sitting near the top of the range is not automatically a markup. And most firms work from a floor: the survey put typical minimum fees at $150 to $350 for individual work, and $350 to $850 once business forms are involved.

That minimum is the most misread part of any quote. If a firm’s floor is $275, a genuinely simple W-2 return still costs $275 there. The office is not gouging you. It has decided it will not open a file for less, because opening a file costs it real money either way. Ask for the minimum on the first phone call and most of the sticker shock disappears before you ever hand over a document.

Why does the same return cost $185 at one office and $400 at another?

Price follows the credential, and there are four rungs. At the bottom is a preparer who holds nothing but a PTIN. Above that sits an Annual Filing Season Program participant, who completed a set number of continuing education hours for that specific tax year. Above them are enrolled agents, CPAs and attorneys — the three groups the IRS grants what it calls unlimited representation rights.

That phrase is what the extra money actually buys. Per the IRS, enrolled agents, CPAs and attorneys may represent any taxpayer on any tax matter before any IRS office, audits and appeals included. An Annual Filing Season Program participant may only represent clients whose returns that participant prepared and signed, and only before revenue agents and customer service representatives — not appeals, not collections. A preparer holding only a PTIN and no credential has no authority to represent you before the IRS at all.

Scarcity explains the rest of the spread. IRS Return Preparer Office figures, current as of August 1, 2026, count 879,698 people holding a current 2026 PTIN. Of those, 208,519 are CPAs, 68,548 are enrolled agents and 26,039 are attorneys, and 72,049 held an Annual Filing Season Program record of completion. The majority of the field carries no credential at all, and the credentialed minority prices accordingly.

An enrolled agent is the credential built specifically around tax rather than around accounting or law. The IRS requires passing a three-part Special Enrollment Examination covering individual returns, business returns and representation, then 72 hours of continuing education every three years. For a lot of households here, an EA is the value pick: the same representation rights as a CPA, and the NATP survey average came in $52 lower on a base 1040.

What does the PTIN requirement actually get you?

It gets a name on your return, which matters more than it sounds. The IRS requires anyone who prepares or assists in preparing a federal tax return for compensation to hold a valid Preparer Tax Identification Number and renew it every year — the 2026 renewal fee is $18.75. A paid preparer must then sign the return and enter that PTIN on it.

The IRS has a name for someone who does the work and refuses to sign: a ghost preparer. IRS guidance is blunt about it — not signing is a red flag that the preparer may be looking to make a quick profit by promising a big refund or charging a fee based on the size of that refund. You are the one who signs the return, and you are legally responsible for what gets filed, no matter who typed it.

Neither state stacks a license on top of that. Missouri does not license or register paid tax preparers, and neither does Illinois — a PTIN is the whole legal bar on both sides of the river, unlike California, Oregon, Maryland or New York, which run their own preparer regimes. Illinois does at least force the number into the open: under Public Act 99-0641, any preparer paid to prepare an Illinois individual or business income tax return must enter a PTIN on it for tax years beginning on or after January 1, 2017. The penalty is $50 per return, capped at $25,000 a year, and an e-filed return is rejected outright when that information is missing. Missouri has no equivalent state rule.

You can check a preparer before handing over a single document. The IRS runs a free, public Directory of Federal Tax Return Preparers with Credentials and Select Qualifications, searchable by ZIP code, listing attorneys, CPAs, enrolled agents, Annual Filing Season Program participants and other credential holders with valid PTINs. Run 63109, 63033, 63376 or 62220 through it and see who is genuinely credentialed near you before you choose.

How much does a tax preparer charge once your return stops being simple?

Every added schedule adds a line to the bill. The 2025 NATP fee survey put common add-ons in larger communities at $53 to $61 for Schedule A, $56 to $66 for Schedule D, and $123 to $135 for Schedule C. Self-employment is the big step: a single Schedule C can roughly double what a plain W-2 return would have cost at the same office.

This metro then adds a multiplier almost nowhere else in Missouri has to think about. Live in Belleville, Edwardsville or Granite City and work in Clayton or downtown, and you file an Illinois resident return plus a Missouri nonresident return, with a credit for taxes paid to the other state that has to be computed rather than guessed. Run it the other direction — O’Fallon, Missouri to a job across the river — and you get the mirror image. Preparers price that as a second state return, every time.

Work performed inside the city limits adds one more filing. The City of St. Louis Collector of Revenue collects the one percent earnings tax from residents of the city regardless of where their employer is located, and from employees of businesses located or performing work inside the city regardless of where those employees live, with individual earnings taxes due by April 15. If it was never withheld, somebody has to prepare that return too.

Rental property behaves the same way. A single-family rental in Maryland Heights or Florissant means a Schedule E, a depreciation schedule that has to be carried forward correctly year after year, and a paper trail nobody wants to reconstruct in 2031. One-time credits add forms of their own: a household claiming residential solar files Form 5695, and the IRS states the Residential Clean Energy Credit equals 30 percent of qualified costs for property installed from 2022 through December 31, 2025 and is not available for property placed in service after that date. If panels are still on your list, read up on solar panels in St. Louis before you budget the tax side of it.

Completely unrelated — if you’re moving before April, find movers across the metro here.

What is a reasonable amount to pay a tax preparer?

A reasonable fee is one whose shape you can see before the work starts. Three structures are common and two of them are fine. Flat per-form pricing — a base for the 1040 plus a stated amount per schedule — is the most predictable, and it is what most people should ask for. Hourly is legitimate when the work is genuinely unpredictable; the 2025 NATP survey put the average set hourly rate at $182, up from $179 in 2023, with half of preparers charging between $129 and $250.

The third structure is the one to walk away from. IRS guidance tells taxpayers to avoid preparers who base their fee on a percentage of the refund, or who offer to deposit any part of the refund into their own account. Circular 230, section 10.27, separately bars credentialed practitioners from charging a contingent fee for preparing an original return. The reason is simple: a fee tied to the refund pays the preparer for making that number bigger, and you are the one who signs underneath it.

Then watch the add-on that is not preparation at all. If you pay the fee out of your refund instead of up front, that is a refund transfer, processed through a temporary bank account opened in your name. The Consumer Financial Protection Bureau has long put typical fees for that product at $30 to $50, and its standing guidance says plainly that neither a refund transfer nor a refund advance loan makes the IRS issue your refund any faster. Putting the fee on a card up front is usually cheaper.

Four questions settle a quote in a single phone call. What is your minimum fee? What does that cover, form by form? What do you charge if the IRS or the state sends a letter about this return later? And are you an enrolled agent, a CPA or an attorney — and will you sign it?

Where can I get free tax help in St. Louis, MO?

If your income is modest, you may not need to pay anyone. The IRS Volunteer Income Tax Assistance program offers free basic return preparation to people who generally make $69,000 or less, to people with disabilities, and to taxpayers with limited English. Tax Counseling for the Elderly serves filers 60 and older, and AARP Foundation Tax-Aide runs seasonal sites in libraries and community buildings on both sides of the river.

For a do-it-yourself return, IRS Free File offered guided software through eight private-sector partners to taxpayers with 2025 adjusted gross income of $89,000 or less, raised from the $84,000 limit used for tax year 2024, with Free File Fillable Forms available above that. IRS Direct File was not available for the 2026 filing season. Our guide to free tax preparation in St. Louis covers the VITA and Tax-Aide options in detail.

Paying for a preparer stops being optional at a fairly predictable point: self-employment income, rental property, a business sale, two states, stock compensation, an inherited IRA, or a letter from a tax agency. Below that line, free is not a lesser product. Above it, a $250 fee is cheap next to one wrong depreciation election repeated for six years.

How much are taxes in St. Louis?

It depends which side of the river you wake up on, and that is exactly why returns here cost more to prepare. Missouri’s top individual income tax rate is 4.7 percent for tax year 2025, and the Missouri Department of Revenue applies it to Missouri taxable income over $9,191 — a threshold low enough that an ordinary household sits at the top marginal rate long before anyone would call its income high.

Illinois takes a different approach entirely: a flat 4.95 percent of net income, a rate the Illinois Department of Revenue has had in place since July 1, 2017, with no brackets to climb. Layer the City of St. Louis one percent earnings tax on earned income over the top of either one, and a Metro East commuter can touch three separate income tax systems on a single paycheck.

None of that changes a preparer’s hourly rate. It changes how many hours your return takes, which is the same thing arriving by a different road.

What does tax season look like from the preparer’s side of the desk?

It is a business with one harvest. In the 2025 NATP fee survey, tax preparation was 65 percent of practice revenue, and 64 percent of the work landed between February and April, against 21 percent in the May-to-October extension months and just 15 percent from November through January. A firm earns most of its year in roughly ten weeks, then carries staff, software and continuing education through the quiet stretch.

That is why minimum fees exist, and why 83 percent of preparers raise prices every one or two years, typically 6 to 10 percent. It is also behind the complaint you hear in every preparer’s office: the shoebox that arrives on April 10, and the February quote for a return that turns out to carry a Schedule C nobody mentioned. Good operators price off scope, in writing, before the folder opens. Being findable is the other half — people search this category locally in January, so a complete listing on St Louis Near Me Directory is what turns a search into a February phone call.

Frequently asked questions

What do tax preparers actually do?

A paid preparer gathers your documents, settles your filing status and residency, applies the deductions and credits you qualify for, prepares the federal return plus any state and local returns, electronically files them, and signs the return with an IRS Preparer Tax Identification Number. Many also handle prior-year returns, amended returns, estimated tax payments and responses to IRS or state notices. What none of them can do is guarantee you a refund.

What are the most common tax services?

Individual Form 1040 preparation is the bulk of it. After that come self-employment returns with Schedule C, rental returns with Schedule E, partnership and S corporation returns, payroll and sales tax filings, bookkeeping, estimated tax planning, amended returns, and representation before the IRS. In the 2025 NATP fee survey, tax preparation made up 65 percent of practice revenue and bookkeeping another 12 percent.

How can I choose a reputable tax preparer?

Check the credential first. The IRS publishes a free Directory of Federal Tax Return Preparers with Credentials and Select Qualifications, searchable by ZIP code, covering attorneys, CPAs, enrolled agents and Annual Filing Season Program participants. Then confirm the preparer will sign the return and enter a PTIN, get the fee structure in writing before work starts, and walk away from anyone whose fee is a percentage of your refund.

Who is the cheapest tax service?

Free is the floor, and for many households it is entirely legitimate. IRS VITA sites serve people who generally make $69,000 or less, plus people with disabilities and limited English speakers, and AARP Foundation Tax-Aide serves filers 60 and older. IRS Free File offered guided software at no cost to 2025 adjusted gross incomes of $89,000 or less. Among paid options, non-credentialed preparers averaged about $185 for a base 1040 in the 2025 NATP survey.

When should I use a tax service?

Pay for help when the return has a moving part you cannot check yourself: self-employment or 1099 income, a rental, a business sale, stock compensation, an inherited IRA, a mid-year move between Missouri and Illinois, or two states at once. Pay as well when a tax agency sends you a letter, because answering one badly costs more than the fee. A single W-2 and a standard deduction rarely justifies it.

What is the $600 rule?

It usually means the old $600 reporting thresholds, and both of them moved. The One Big Beautiful Bill Act, signed July 4, 2025, restored the Form 1099-K threshold to more than $20,000 and more than 200 transactions, cancelling the planned drop to $600. The same law raised the Form 1099-NEC and 1099-MISC threshold from $600 to $2,000 beginning with tax year 2026, indexed for inflation after that. Income stays taxable whether or not a form shows up.

What is the IRS 7 year rule?

It is a records rule, not a blanket deadline. The IRS says to keep records for seven years if you file a claim for a loss from worthless securities or a bad debt deduction. Six years applies if you failed to report income you should have reported and it is more than 25 percent of the gross income shown on the return. Three years covers the ordinary case, and property records are kept until the property is sold.

Who is eligible for the $6000 senior tax credit?

It is a deduction rather than a credit. Under the One Big Beautiful Bill Act, a taxpayer who reaches age 65 on or before the last day of the tax year may claim an additional $6,000 deduction for tax years 2025 through 2028, or $12,000 for a married couple where both spouses qualify. It is available whether or not you itemize, and it phases out above $75,000 of modified adjusted gross income, or $150,000 for joint filers.

What are the biggest tax mistakes people make?

Assuming income is invisible because no form arrived, since the reporting thresholds moved but the tax did not. Filing one state after living or working in two. Forgetting the City of St. Louis one percent earnings tax when nobody withheld it. Losing the depreciation carryforward on a rental. Signing a return the preparer would not sign. And discarding records early, when the IRS keeps three, six and seven year windows depending on the issue.

How much income tax will I pay in Missouri if I earn $100,000 per year?

Roughly $3,800 in Missouri income tax alone, for a single filer taking the standard deduction with nothing unusual in the return. The Missouri Department of Revenue sets the 2025 standard deduction at $15,750 for a single filer and applies the 4.7 percent top rate to Missouri taxable income over $9,191. That is state tax only — federal income tax, Social Security and Medicare, and the city earnings tax on wages earned inside St. Louis all sit on top.

The two quotes you got in February were both real prices, for two different products. One buys a return typed and filed. The other buys somebody who can stand between you and the IRS if a letter arrives in October. Decide which one your situation calls for — then ask for the minimum fee in writing before you hand anybody the folder.
