Bookkeeping, sales tax and taxes

A photography business can be busy and profitable on paper yet still run out of money, miss a tax deadline or face penalties for poor records. Financial management is not glamorous, but it is what keeps the business alive between jobs. This lesson covers bookkeeping systems, the difference between profit and cash, cash-flow forecasting with deposits, sales taxes, income tax and self-employment contributions, installments or estimated payments, and the most common deductions photographers claim, such as home offices and vehicles. CRE-330 covers creator taxes in more depth, including corporations and retirement savings. Tax rules change every year; figures here are for 2026 where stated and should be checked against current government guidance or with an accountant.

Bookkeeping basics

Bookkeeping is the routine recording of every financial transaction: income received, expenses paid, money owed to you and money you owe. Good bookkeeping makes tax filing straightforward, shows whether the business is profitable, and provides evidence if the tax authority asks questions.

  • Separate accounts: use a business bank account and card for all business transactions, so personal and business spending do not mix.
  • Chart of accounts: group transactions into categories, such as session revenue, licensing revenue, print sales, equipment, software, insurance, marketing, travel, assistants and professional fees.
  • Receipts and invoices: keep a digital copy of every receipt and invoice, linked to the transaction. Most accounting apps let you photograph receipts.
  • Regular routine: record and reconcile transactions weekly or monthly, matching your records to bank statements.
  • Reports: review a monthly profit and loss statement and cash balance, and an annual balance sheet.

Accounting software designed for small businesses can import bank transactions, issue invoices, track sales tax and produce reports. Choose one your accountant can work with.

Record keeping rules

In the United States, the IRS generally expects records to be kept for at least three years after filing, and longer in some cases, such as six years if income is substantially underreported and as long as you own equipment plus three years after you sell it. Most small businesses may use the cash method, recognizing income when received and expenses when paid, which makes the timing of deposits and purchases important for tax planning.

Profit is not cash

Profit is revenue minus expenses for a period. Cash is the money actually in your account. The two differ because of timing: a client may owe you $5,000 for a job finished last month, so it counts as revenue but is not yet cash; a camera bought for cash is deducted gradually through depreciation, so your cash fell more than your expenses; deposits for next year's weddings arrive as cash before the work is done. A business can be profitable but run out of cash, especially if it grows quickly or works in strong seasons.

Cash-flow forecasting

A cash-flow forecast predicts cash coming in and going out each month and the resulting balance. For photographers with seasonal work and deposits, it is one of the most useful tools in the business, because it reveals months when cash will run short before they arrive.

Worked problem

Fixing a cash shortfall

In the forecast above, the balance falls to −$3,000 in April. Suggest two changes that would keep the balance positive, and check one of them.

Show solution
  1. Option 1: delay the $3,000 lens purchase from March to June, after wedding balances arrive.
  2. Check: March closing becomes \( 8000 + 3000 - 5500 = \$5500 \); April becomes \( 5500 + 2000 - 7500 = \$0 \); May \( 0 + 9000 - 5500 = \$3500 \); June after buying the lens \( 3500 + 14\,000 - 8500 = \$9000 \).
  3. Option 2: hold a cash reserve of at least one month of payments, or collect a second installment from couples 90 days before the wedding.

Answer: Moving the lens purchase keeps cash at or above zero, though April is still tight. Combining it with a reserve or an earlier installment schedule gives a safer margin. The forecast showed the problem two months early.

Sales taxes

The United States has no national sales tax. Forty-five states and the District of Columbia have state sales taxes, and many cities and counties add local taxes. Whether photography is taxable varies widely: many states tax prints, albums and other tangible products; some also tax photography services or digital image files; others exempt services. Check your state's rules carefully, because a portrait package that includes prints may be partly or wholly taxable.

If you sell taxable items, register for a sales tax permit in your home state. When you sell to customers in other states, you may also have to register there if you exceed that state's economic nexus threshold, commonly $100,000 of sales into the state in a year, following the 2018 Supreme Court decision in South Dakota v. Wayfair. Online marketplaces and print-on-demand platforms usually collect and remit sales tax on sales they facilitate.

Worked problem

Sales tax registration

A photographer in a state that taxes prints sold $6,000, $9,500, $8,000 and $7,800 of taxable products to customers in a neighboring state over a year. That state's economic nexus threshold is $100,000. Must she register there? In her home state, if she charges a 7% combined sales tax on $1,200 of taxable prints, how much tax does she collect?

Show solution
  1. Total sales into the neighboring state: \( 6000 + 9500 + 8000 + 7800 = \$31\,300 \), below $100,000.
  2. She need not register in the neighboring state on this test, but should check whether it also counts transactions; home-state tax: \( 0.07 \times 1200 = \$84 \).
  3. She remits the $84 to her home state; sales tax paid on supplies she resells may be avoided with a resale certificate.

Answer: No registration is needed in the neighboring state on these figures; she collects and remits $84 at home.

Income tax and self-employment contributions

Self-employed photographers in the United States report business income on Schedule C and pay federal income tax at graduated rates, plus state income tax in most states. In addition, they pay self-employment tax of 15.3% on 92.35% of net earnings: 12.4% for Social Security up to the 2026 wage base of $184,500, and 2.9% for Medicare with no cap, plus an additional 0.9% Medicare tax above $200,000 for single filers. Half of self-employment tax is deductible. Many sole proprietors can also claim the qualified business income deduction of up to 20% of qualified business income, which the 2025 tax law made permanent, subject to income limits.

If you expect to owe $1,000 or more for the year, you generally must make quarterly estimated tax payments, due around April 15, June 15, September 15 and January 15. You can avoid underpayment penalties by paying at least 90% of the current year's tax or 100% of the previous year's tax (110% if adjusted gross income exceeded $150,000).

Worked problem

Self-employment contributions

An American photographer has net self-employment income of $60,000 in 2026. What self-employment tax does she pay, and how much should she set aside monthly for it?

Show solution
  1. Net earnings subject to the tax: \( 60\,000 \times 0.9235 = \$55\,410 \).
  2. Tax: \( 55\,410 \times 0.153 = \$8477.73 \); earnings are below the wage base, so the full rate applies.
  3. Monthly set-aside: \( 8477.73 / 12 \approx \$706 \), in addition to income tax.

Answer: About $8,478 in self-employment tax, or about $706 a month. Many photographers transfer a fixed percentage of every payment, such as 25 to 30%, to a separate tax savings account.

Common deductions

Business expenses that are reasonable and incurred to earn income are generally deductible. For photographers these include software and subscriptions, insurance, marketing, professional fees, association dues, education related to the current business, studio rent, assistants and contractors, props and supplies, phone and internet (business share), travel for jobs, and equipment through depreciation (Lesson 10).

Home office: you may deduct home office expenses if part of your home is used regularly and exclusively as your principal place of business or to meet clients. The simplified method allows $5 per square foot for up to 300 square feet, a maximum of $1,500; the regular method allocates actual costs by area. Vehicle: you may use either actual costs multiplied by the business-use share or the standard mileage rate, which is 72.5 cents per mile for 2026, plus parking and tolls; keep a mileage log either way.

Paying yourself

Sole proprietors do not pay themselves a salary in the legal sense; they draw money from the business, and tax is based on the business's net income, not on the amount drawn. Even so, paying yourself a regular, planned amount each month, rather than taking money whenever the account looks full, makes personal budgeting easier and keeps enough in the business for taxes, equipment and slow seasons. A common system divides each payment received into separate accounts: a share for tax, a share for operating expenses, a share for profit or savings and the remainder for owner pay. Reviewing the percentages each quarter keeps the system aligned with actual results.

Working with an accountant

An accountant who understands self-employed creatives can save more than their fee through correct deductions, timing of purchases, installment planning and advice on structure. Give them organized records: categorized transactions, reconciled bank statements, sales tax returns, a list of equipment bought and sold, mileage or vehicle logs, and home office measurements. Meet before year end, not just at filing time, so there is still time to act on their advice, such as buying needed equipment before the year closes or setting aside more for tax. Ask them to explain any figure you do not understand; you remain responsible for what is filed in your name.

Key financial ratios

Three ratios give a quick picture of financial health. Gross margin, revenue minus direct costs divided by revenue, shows how much each sale contributes to overheads and profit. Net margin, profit divided by revenue, shows overall profitability. Days sales outstanding, the average number of days clients take to pay, shows how quickly invoices turn into cash. Tracking these each quarter reveals trends long before they become crises.

Set calendar reminders for every filing and payment date at the start of the year, with a week's warning, so deadlines never arrive as surprises.

Common mistakes

  • MistakeMixing personal and business transactions

    InsteadUse separate accounts and record every transaction with a receipt.

  • MistakeConfusing profit with cash

    InsteadPrepare a monthly cash-flow forecast, especially in seasonal businesses.

  • MistakeIgnoring sales tax thresholds

    InsteadTrack taxable sales each quarter and register when required.

  • MistakeSpending all receipts and facing a large tax bill

    InsteadSet aside a fixed percentage of every payment in a tax account.

  • MistakeClaiming vehicle costs without a log

    InsteadKeep a logbook or mileage app to support the business share.

Summary and key terms

  • Bookkeeping records every transaction in categories, with receipts and regular reconciliation.
  • Profit and cash differ because of timing; deposits and purchases can create cash crunches.
  • A cash-flow forecast reveals shortfalls months in advance.
  • Sales tax rules differ: GST/HST in Canada with a $30,000 small supplier threshold; state rules and economic nexus in the United States.
  • Self-employed photographers pay pension contributions or self-employment tax in addition to income tax.
  • Installments or estimated payments are due quarterly when tax owing exceeds set thresholds.
  • Home office and vehicle deductions require clear records of business use.
