How Much Does Startup Accounting and Tax Cost in 2026?

For a venture-backed Delaware C-Corp at pre-seed to Series A, a full year of bookkeeping, federal and state returns, Delaware filings and a 409A usually lands between $10,000 and $20,000, before any fractional CFO. For a solo founder with no revenue, no employees and a few dozen transactions a month, the honest number is closer to $1,000 to $2,000 a year.

The spread is wide because founders are buying very different things under the same label. Part of the bill is fixed by governments and does not change with who you hire. The rest is professional fees, which scale with four drivers:

• Transaction volume, and cash versus accrual books.
• The number of states where you have employees, offices or enough sales to owe tax.
• Whether a foreign person owns 25% or more of the company.
• Claiming the R&D credit or granting options (which needs a 409A).

A simple decision rule: if none of those four drivers apply to you yet, buy per-return help and keep your own books. Once two or more apply, a startup-focused firm on a fixed monthly fee is usually cheaper than assembling freelancers, because the expensive mistakes happen in the gaps between providers.

The figures in this guide come from two kinds of sources. Government fees and penalties are from the Delaware Division of Corporations, the IRS and the California Franchise Tax Board, checked on November 13, 2026. Professional fees are typical market ranges based on our read of startup-firm and freelancer pricing, not a survey; treat them as a sanity check for quotes, not a price list.

Every Delaware corporation pays an annual report fee and franchise tax by March 1, keeps a registered agent, and pays tax in any other state where it does business. These costs are identical if you file yourself or hire the most expensive firm in the country.

Delaware's figures, from the Division of Corporations:

• Annual report fee: $50 for a non-exempt domestic corporation.
• Franchise tax minimum: $175 under the Authorized Shares Method, $400 under the Assumed Par Value Capital Method (APVC). Maximum $200,000 ($250,000 for Large Corporate Filers).
• Late filing penalty: $200, plus interest of 1.5% per month on unpaid tax.
• Registered agent: Delaware requires an agent with a street address and office in the state (8 Del. C. §132). Commercial agents charge a market fee, typically about $50 to $300 a year.

The franchise tax is where founders panic. Delaware's default invoice uses the Authorized Shares Method: $250 for 5,001 to 10,000 shares, plus $85 for each additional 10,000 shares or portion. A startup with 10,000,000 authorized shares is billed $250 + ($85 x 999) = $85,165.

The APVC method usually fixes that. Take a hypothetical seed company with 10,000,000 authorized shares at $0.00001 par, 8,000,000 issued, and $1,500,000 of total assets on its Form 1120 Schedule L:

1. Assumed par: $1,500,000 / 8,000,000 = $0.187500.
2. All authorized shares have a par below that, so assumed par value capital is $0.1875 x 10,000,000 = $1,875,000.
3. Round up to the next whole million (2) and multiply by $400: $800.

Same company, $800 instead of $85,165. Your accountant should run both methods every year before you pay.

Other states add their own minimums. California, for example, charges corporations doing business there an $800 minimum franchise tax each year, although newly incorporated or newly qualified corporations are exempt from the minimum in their first taxable year.

The table below prices each item three ways. Government fees are primary-sourced; everything marked as a range is a typical market range as of late 2026, not a quote from any specific vendor.

Three things the table hides. First, DIY is cheap only if your time is cheap and your facts are simple; a C-Corp return has balance sheet schedules (Schedule L, M-1) that do not exist on a personal return. Second, freelancer quotes often cover only the federal return, so add every state line yourself. Third, a startup firm's monthly fee should be converted to an annual total and compared against the sum of the rows you actually need, not against one row.

A Form 1120 for a simple, pre-revenue C-Corp can cost a few hundred dollars from a marketplace preparer, and for some companies that is the right purchase. Founders in public threads report paying around $500 for exactly this. The question is not whether $500 is a fair price for the federal form; it is what else your company owes that the $500 does not cover.

Before accepting the cheapest quote, check it against this list:

• Federal Form 1120, due the 15th day of the 4th month after year end (April 15 for calendar-year companies). Required every year the corporation exists, even with zero revenue.
• Form 7004 extension, which gives an automatic six months to file but does not extend the time to pay.
• Every state income or franchise return where you have employees, an office or taxable sales.
• Delaware franchise tax recalculated under the APVC method, using the Schedule L assets from the federal return.
• Form 5472 if a foreign person owns 25% or more.
• Form 6765 if you are claiming the R&D credit, filed with the original return.

IRS penalties for a late Form 1120 are 5% of the unpaid tax for each month or part of a month late, up to 25%. For a return due in 2026 and filed more than 60 days late, the minimum penalty is the smaller of the tax due or $525. Late payment adds 0.5% per month, also capped at 25%. For a loss-making startup with no tax due, the federal late-filing penalty may be small. The expensive misses are the information returns and elections that ride on the 1120, covered in the next two sections.

Our view: a cheap federal return is fine when the preparer asks about states, foreign ownership and R&D before quoting. If they do not ask, the price is low because the scope is.

If a foreign person owns 25% or more of your Delaware C-Corp, the cheapest safe setup is a preparer who files Form 1120 with Form 5472 attached every year, usually for roughly $800 to $3,500 combined as a typical market range. The cheapest unsafe setup is filing the 1120 alone.

The IRS assesses a $25,000 penalty on a reporting corporation that fails to file Form 5472 on time and in the required manner. If the failure continues more than 90 days after IRS notice, another $25,000 applies for each 30-day period. That single penalty is larger than the total cost of compliant filing for a decade at the ranges above.

What founders outside the US get wrong:

• Assuming no revenue means no filing. Capital contributions, founder loans and the company paying a founder's expenses are all reportable related-party transactions.
• Treating a foreign-owned single-member LLC like a C-Corp. A foreign-owned disregarded entity files Form 5472 attached to a pro forma Form 1120, and it cannot be filed electronically.
• Forgetting the state side. A Delaware C-Corp with a contractor or employee in a US state may owe that state a return.

A first-year budget for a hypothetical pre-revenue, foreign-owned C-Corp with no US employees: Delaware $400 APVC minimum + $50 annual report + $150 registered agent + about $1,500 for a preparer handling Form 1120 and Form 5472 = $2,100. That is a realistic floor. Quotes far below it usually leave out the 5472 or the Delaware recalculation.

These three items are optional in the sense that no law requires them every year, but each has a clear trigger, and skipping them once the trigger hits usually costs more than buying them.

R&D credit. A qualified small business (gross receipts under $5 million for the year, with no gross receipts before the five-year period ending with that year) can apply up to $500,000 of research credit against employer payroll taxes. The election must be made on the original return by its due date, including extensions. Under the alternative simplified credit in IRC §41(c)(4), a company with no qualified research expenses in any one of the prior three years gets 6% of current-year QREs. On $400,000 of US engineering wages that qualify, that is 6% x $400,000 = $24,000. A study priced at a few thousand dollars pays for itself several times over. Below roughly $100,000 of QREs, the math gets thin, and a firm that bundles the credit into its fee is worth more than one charging a separate study.

409A valuation. You need one before granting options, and again after a priced round or a material change. A typical market range for a seed or Series A company is about $2,000 to $5,000. Trigger: your first option grant.

Fractional CFO. Typical market ranges run about $3,000 to $12,000 a month on retainer, or about $150 to $450 an hour for project work. Our rule of thumb: a seed company with one product, one entity and no fundraise in the next year does not need a retainer; a company preparing a Series A data room or building its first operating model often needs a few months of project work.

Trigger checklist: hired your first US engineer (R&D), about to grant options (409A), raising in the next six months (CFO project).

Here is a full-year budget for a hypothetical seed-stage company, built from the government fees above and the middle of the typical market ranges. Your numbers will differ; the method is the point.

Assumptions: Delaware C-Corp in its second tax year, US founders, $1.5 million seed raised, $1,500,000 of total assets at year end, 10,000,000 authorized shares at $0.00001 par with 8,000,000 issued, four employees in California, $400,000 of qualifying US research wages, and a first 409A for option grants.

Government fees:

• Delaware franchise tax under APVC: $800 (worked earlier).
• Delaware annual report: $50.
• Registered agent: $150 (assumed, within the $50 to $300 range).
• California minimum franchise tax: $800 (second taxable year, operating at a loss).
• Subtotal: $800 + $50 + $150 + $800 = $1,800.

Professional fees, bought item by item:

• Cash-basis bookkeeping: $600 x 12 = $7,200.
• Federal Form 1120 plus California return: $2,500.
• 1099 preparation: $300.
• 409A valuation: $3,000.
• R&D credit study: $5,000 (assumed flat fee).
• Subtotal: $7,200 + $2,500 + $300 + $3,000 + $5,000 = $18,000.

Total spend: $1,800 + $18,000 = $19,800.

Now the offset. The R&D credit at 6% x $400,000 = $24,000 can be applied against employer payroll taxes after the return is filed. Net of the credit, the year's accounting and tax cost is $19,800 - $24,000 = -$4,200. In other words, done properly, compliance for this company is cash-positive in year two.

The same company without the R&D election saves $5,000 on the study and loses $24,000 of credit, a net cost of $19,000. That is why we tell seed teams with engineers to budget for the study before they budget for anything optional.

Cheaper is fine, and often correct, when your company is a solo founder or two co-founders, has no revenue, no employees, no foreign owners, no option grants, and fewer than about 50 transactions a month. In that situation, paying $5,000 a year for a full-service bookkeeping and tax package is money you could spend on product.

A lean setup for that company, using the same sources:

• Delaware: $400 APVC minimum (assuming small gross assets) + $50 annual report = $450.
• Registered agent: about $150.
• Bookkeeping: do it yourself in accounting software, reconciled monthly.
• Federal Form 1120: a credentialed per-return preparer at roughly $500 to $1,000.
• Total: roughly $450 + $150 + $500 to $1,000 = $1,100 to $1,600 a year, plus software.

The conditions that should make you stop doing it this way:

1. You hire your first employee or contractor in a US state other than Delaware.
2. You start paying US engineers (the R&D payroll election is now worth real money).
3. A foreign person owns 25% or more.
4. You grant options, or close a priced round.
5. Your books need to survive investor diligence.

One caution on DIY. Keeping your own books is reasonable at this stage; preparing your own Form 1120 is possible but a poor trade for most founders, because the preparer's real job is catching the things you do not know to ask about. Pay for a credentialed preparer even when everything else is DIY.

The costs that blow up a startup's accounting budget are rarely the monthly fee. They are catch-up work, per-state add-ons, amendments and penalties, and most of them are visible in a quote if you know where to look.

• Catch-up bookkeeping. If your books are behind, many providers charge a separate cleanup fee, often priced per month of backlog (at SpryTax the cleanup is included in the plan). Get it quoted as a fixed amount before you sign.
• Per-state pricing. A quote that covers "federal and one state" becomes much larger once you have remote employees in three states. Ask for the per-state price in writing.
• Amended returns. Fixing a wrong return with Form 1120-X is billed as new work by almost every provider, and missed elections (like the R&D payroll election) generally cannot be fixed by amending.
• Penalties. Form 5472 at $25,000 per form; Delaware's $200 late annual report penalty plus 1.5% monthly interest; IRS late filing at 5% per month of unpaid tax.
• Delaware paid off the default invoice. Paying $85,165 under the Authorized Shares Method when APVC gives $800 is the most avoidable overpayment we see.
• Hourly notice work. IRS and state notices billed hourly, with no estimate.
• Software pass-through fees. Some quotes add accounting, payroll or bill-pay software on top.
• Platform risk. When a provider shuts down, you pay again to rebuild. Founders re-pricing after Bench's shutdown at the end of 2024 learned to ask one question first: do we own the accounting file and every login?

A quick test: ask each provider to list, in the engagement letter, every return and filing covered for the year and every item billed separately. Anyone who will not put that in writing is telling you how the bill will grow.

Convert every quote to one annual number that covers the same filing list, then compare. Monthly fees, per-return fees and hourly rates are not comparable until you do.

1. List the filings you owe this year: Form 1120, each state return, Delaware franchise tax and annual report, 1099s, Form 5472 if foreign-owned, Form 6765 if claiming R&D.
2. For each quote, mark which items are included, which are extra, and which are missing.
3. Price the extras and missing items using the ranges in the line-item table.
4. Add government fees (they are the same for every quote, so they only matter for the total budget, not the comparison).
5. Add a buffer for notices and questions if the provider bills hourly. Four hours at $300 is $1,200.
6. Compare annual totals, then compare who signs the return and who owns the data.

An example with two hypothetical quotes. Provider A: $450 a month bookkeeping plus $2,000 for the federal return: $450 x 12 + $2,000 = $7,400, plus one state return at $500 and the R&D study at $5,000, for $12,900. Provider B: $650 a month including the federal return, one state and the R&D credit: $650 x 12 = $7,800. The cheaper-looking quote is $5,100 more expensive for the same work.

Then check credentials. The person signing the return should be a CPA or enrolled agent you can look up on a public registry.

SpryTax charges a flat monthly fee with no setup fees: Founder $299/month, Growth $599/month, Scale $1,299/month. Federal Form 1120 filing is included in every plan.

• Founder, $299/month ($3,588 a year): business formation, federal Form 1120 filing (also 1120-S and 1065), quarterly estimated payments, a compliance calendar, email support. Payroll, R&D credits and stock option planning are not included.
• Growth, $599/month ($7,188 a year): everything in Founder, plus payroll for up to 10 employees, R&D credit applications, monthly financial statements with books closed by day 10, stock option compliance, phone support and a dedicated account manager.
• Scale, $1,299/month ($15,588 a year): everything in Growth, plus unlimited payroll, international tax compliance (including Form 5472 and transfer pricing), crypto accounting, 409A valuation support, M&A tax planning and CFO-level consultation.
• Fractional CFO: available as an add-on, priced by scope.

Anything outside your plan is quoted up front and approved by you before we start, and messy books get two weeks of cleanup, included in the plan, before the monthly cadence begins. Bookkeeping and accounting on its own starts at $399/month, and payroll on its own at $199/month.

Where we fit, honestly. For the seed company in the worked budget, assuming the California return and R&D documentation fall inside the scope we quote, Growth at $7,188 plus $1,800 of government fees and a $3,000 409A comes to $11,988, compared with $19,800 bought item by item. For a solo founder with no revenue, our Founder plan at $3,588 a year costs more than a $500 to $1,000 per-return preparer, and the lean setup above may be the better choice until you hire. For a pre-revenue foreign-owned company, Scale is more than you need on day one; ask us for a scoped quote instead.
