Accountants and bookkeepers spend their days finding deductions for clients, then often shortchange themselves at tax time. The deductions available to a CPA firm or a solo bookkeeper are specific: tax-prep software per-return fees, CPE hours, professional liability insurance, and the IRS-required Written Information Security Plan that every paid preparer must maintain. Legitimate deductions for an accounting practice follow specific IRS rules, and a clean banking workflow makes them easier to substantiate.

Why should accountants and bookkeepers track business expenses separately?

Every dollar of legitimate business expense reduces taxable income. For a sole proprietor filing Schedule C, it can also reduce net earnings subject to self-employment tax. The IRS requires that deductible expenses be both ordinary (common in your trade) and necessary (helpful and appropriate for your business) under IRC §162.

Even tax professionals benefit from separating personal and business finances. A dedicated business checking account creates a clean audit trail that ties every transaction to a date, payee, and amount, which is the substantiation the IRS asks for under Treasury Regulation §1.6001-1. Commingling personal and business accounts can make deductions harder to substantiate and may weaken the separation between an LLC and its owner.

Novo business checking has no monthly fees, no minimum balance requirements, and direct integrations with QuickBooks Online, Xero, and Stripe for reconciliation.

Which expenses are tax-deductible for accounting and bookkeeping firms?

Most expenses for a typical practice fall into these core categories. Each is deductible on Schedule C for sole proprietors, on Form 1120-S for S-corps, or on Form 1065 for partnerships.

• Office rent, utilities, and coworking fees. Full deduction for dedicated business space. If you sublet a desk at a coworking space, the monthly membership is deductible.
• Accounting and tax software. QuickBooks Online, Xero, Drake Tax, Lacerte, ProConnect, UltraTax, and ProSeries subscriptions are deductible in the year paid. Per-return e-filing fees count too.
• Professional liability insurance (E&O) and general business insurance. Errors-and-omissions premiums are fully deductible, as are cyber liability and general liability policies.
• Continuing professional education and licensing. CPE courses, CPA license renewals, AICPA membership dues, and state society dues all qualify.
• Client acquisition costs. Website hosting, SEO, paid ads, referral fees to other professionals, and printed marketing material.
• Bank fees and payment processing. Stripe, Square, or ACH processing fees, merchant service charges, and any bank fees you do incur.

How do home office and equipment deductions work for accountants?

Many accountants and bookkeepers work from a home office at least part of the week. The IRS offers two methods.

Simplified method. Deduct $5 per square foot of dedicated office space, up to 300 square feet, for a maximum of $1,500 per year. No depreciation, no recapture, minimal paperwork.

Actual expense method. Calculate the business-use percentage of your home (office square footage divided by total square footage) and apply that percentage to mortgage interest or rent, utilities, insurance, repairs, and depreciation. More paperwork, often a larger deduction for owners of larger homes.

The office must be used regularly and exclusively for business. A desk in a guest room that is also used for personal activities generally does not meet the exclusive-use requirement.

For equipment, Section 179 allows businesses to elect to expense qualifying business property in the year it is placed in service, subject to IRS limits and eligibility rules. Qualifying property typically includes computers, dual monitors, printers, and office furniture. Many firms use secure document scanners such as Fujitsu ScanSnap, along with ergonomic chairs and sit-stand desks.

Which software and technology costs can accountants deduct?

This is where accounting and bookkeeping practices differ most from a generic small business. The tech stack is large, recurring, and fully deductible.

• Tax preparation software: Drake, Lacerte, ProConnect Tax Online, UltraTax CS, ATX, ProSeries. Includes per-return e-filing charges.
• Practice management: Karbon, Canopy, TaxDome, Financial Cents, Jetpack Workflow.
• Client portals and secure file exchange: SmartVault, ShareFile, TaxDome's portal, Liscio.
• Cybersecurity and WISP compliance: password managers (1Password, Bitwarden), endpoint protection, encrypted email (Verifyle, Encyro), and a documented Written Information Security Plan.

The IRS requires every paid tax return preparer with a PTIN to create, maintain, and follow a Written Information Security Plan that protects taxpayer data, under the Gramm-Leach-Bliley Act Safeguards Rule enforced by the FTC.

The cost of WISP software, security audits, and required employee training is deductible.

What professional development and licensing costs are deductible?

Education that maintains or improves skills required in your current trade is deductible. Education that qualifies you for a new trade is not, which is why initial CPA exam fees and review courses are a gray area. The IRS position in Treas. Reg. §1.162-5 is that education needed to meet the minimum requirements of a profession is not deductible. CPA exam fees for a non-CPA accountant are generally not deductible. CPE for a licensed CPA clearly is.

Deductible in this category:

• CPE courses and conference registration (AICPA ENGAGE, Scaling New Heights, state society conferences)
• State CPA license renewal fees and EA enrollment renewal
• Professional memberships (AICPA, NATP, NSA, NACPB, state CPA societies)
• Research subscriptions: Thomson Reuters Checkpoint, CCH AnswerConnect, The Tax Adviser
• Industry publications and reference materials

How are travel, meals, and client entertainment deducted?

Driving between client offices is deductible at the IRS standard mileage rate. For 2024, the IRS standard mileage rate for business use of a car is 67 cents per mile.

Keep a contemporaneous log with the date, destination, business purpose, and miles. Apps like MileIQ or the mileage tracker inside QuickBooks Self-Employed handle this automatically.

Commuting from home to a regular office is not deductible. Driving from a home office to a client site is.

Business travel for conferences, training, or out-of-town client work can include flights, hotels, and ground transportation, all fully deductible. Meals while traveling overnight for business are deductible at 50%.

Client meals are deductible at 50%. Entertainment expenses such as sporting events, concerts, and golf rounds are no longer deductible after the Tax Cuts and Jobs Act of 2017.

If you take a client to a baseball game, the hot dog is potentially 50% deductible if you keep a separate receipt; the ticket is not.

Client gifts are deductible up to $25 per recipient per year under IRC §274(b). A $200 bottle of wine for your best client gets you a $25 deduction.

How do self-employment tax and the QBI deduction affect accountants?

Solo practitioners pay self-employment tax on net earnings from self-employment. The combined self-employment tax rate is 15.3%, made up of 12.4% Social Security on earnings up to the annual wage base plus 2.9% Medicare with no cap. Half of SE tax is deductible above the line.

The Qualified Business Income deduction under IRC §199A allows eligible pass-through owners to deduct up to 20% of qualified business income. Accounting is classified as a Specified Service Trade or Business (SSTB), which means the deduction phases out once taxable income exceeds the threshold.

For SSTB income above the upper phase-out threshold, the QBI deduction is generally unavailable, subject to current-year thresholds and filing status.

Practical implications for a CPA or bookkeeper near the phase-out:

• Maximize retirement contributions to a SEP-IRA or Solo 401(k) to drop taxable income below the threshold. A Solo 401(k) allows employee deferrals plus employer contributions, often higher total contributions than a SEP for the same income.
• Self-employed health insurance premiums are deductible above the line and reduce AGI.
• HSA contributions for those on a high-deductible health plan also reduce AGI.
• S-corp election can change the calculus by splitting income between W-2 wages and distributions, but the SSTB classification still applies.

If you are within $50,000 of the SSTB threshold, consider having another tax professional review the planning assumptions or run the numbers through software like Holistiplan.

How can Novo help accounting and bookkeeping firms stay organized?

A clean books-to-bank tie-out makes these deduction claims easier to substantiate. Novo business checking connects with the accounting tools many firms already use. For a deeper look at how Novo fits an accounting practice specifically, see our guide to the best business checking for accountants and bookkeepers.

• No monthly fees, no minimum balance. Novo does not charge a monthly account fee, so routine account maintenance does not reduce your balance.
• Direct integrations with QuickBooks Online, Xero, Stripe, and Shopify push transactions into your books automatically. For a bookkeeping firm running its own books in QuickBooks Online, this can reduce manual CSV imports.

• Novo Reserves let you carve out funds for quarterly estimated taxes, payroll, or a CPE budget without opening separate accounts. Set a percentage of each deposit to move into a tax Reserve so quarterly tax money is separated before it is spent.
• Free incoming wires and unlimited transactions with no transaction fees. Useful when a corporate client pays a five-figure engagement by wire.
• No-fee ACH transfers and built-in invoicing tools for billing clients directly from your account.

One honest tradeoff: Novo does not accept cash deposits. For an accounting practice that occasionally receives a cash payment, that means a workaround such as a money order, or depositing cash at a bank you have a relationship with and transferring the funds to Novo. That tradeoff matters for any firm that receives client payments in cash or needs to deposit cash reimbursements.

Paste this block into ChatGPT or Claude with a prompt like "Turn this into a Google Sheet with a Category dropdown matching Schedule C lines, a column that auto-applies the 50% meals haircut, and a pivot table summarizing deductions by category for 2024." An AI tool can draft spreadsheet formulas or a template structure, but you should review the output before using it for tax records.

Frequently asked questions

Can accountants deduct their own CPA exam fees?

Generally no. The IRS treats education required to meet the minimum qualifications of a profession as a personal expense under Treas. Reg. §1.162-5. CPA exam fees and review courses for someone working toward initial licensure are not deductible. Once you are a CPA, CPE required to maintain the license is fully deductible.

Is client gift-giving deductible for bookkeepers?

Yes, capped at $25 per recipient per year under IRC §274(b). Branded promotional items under $4 (pens, notepads with your logo) and items clearly for business use in the recipient's office are excluded from the cap. A $25 deduction is small, but the goodwill is the point.

How should I track mileage between client offices?

Use a contemporaneous log with date, starting location, destination, business purpose, and miles. Apps like MileIQ, Everlance, or the mileage tracker built into QuickBooks Online auto-classify trips. The IRS can disallow mileage deductions if your log is reconstructed after the fact, so set the app up before tax season, not after.

What records does the IRS require for expense substantiation?

Under Treas. Reg. §1.6001-1, you must keep records that establish the amount, date, place, and business purpose of each deduction. For meals and travel, IRC §274(d) imposes stricter substantiation: keep the receipt, note who attended, and document the business purpose. Bank and credit card statements alone are not sufficient for §274(d) items; you need the underlying receipt.

Do I need a WISP if I only prepare a few returns a year?

Yes. The IRS requires every paid preparer with a PTIN to have a written information security plan, regardless of practice size. Publication 5708 walks through a sample WISP, and several vendors (Tech 4 Accountants, Rightworks) sell templates and training.

Is Novo a good fit for a one-person bookkeeping practice?

Yes for most. No monthly fees, direct QuickBooks Online and Xero feeds, and Reserves for quarterly taxes cover the core needs of a solo bookkeeper. The one limitation is cash deposits, which Novo does not accept. So firms that receive cash payments need another way to convert cash into electronic funds before transferring money to Novo.
