Bookkeeping, records and estimated taxes for carpet cleaners

What the IRS says about separating business money, which records to keep and for how long, logging vehicle miles, and paying estimated tax.

Updated November 5, 2026 · 6 min read · By CarpetOS

Tax season shows whether your records work. Can you prove what the business earned, what it spent on chemicals and fuel, and how far the van drove for jobs? Did you set money aside, or is a large bill waiting in April?

This guide explains what the IRS says about separating business money, which records to keep and for how long, tracking vehicle use, and paying estimated tax during the year. It covers federal rules; your state may have its own income tax and payment rules. Nothing here is tax advice, so confirm your situation with the IRS or a tax professional.

Keep business money separate

IRS Publication 583, Starting a Business and Keeping Records (revised December 2024) says "One of the first things you should do when you start a business is open a business checking account. You should keep your business account separate from your personal checking account." It says to deposit all daily receipts there and to "Use the business account for business purposes only."

It also suggests noting the source of each deposit and reconciling the account each month. As the IRS page on what kind of records to keep puts it, "For most small businesses, the business checking account is the main source for entries in the business books."

What records to keep

The IRS recordkeeping page says "You may choose any recordkeeping system suited to your business that clearly shows your income and expenses." Paper and software both work, and the IRS page on what kind of records to keep adds that "All requirements that apply to hard copy books and records also apply to electronic records." Publication 583 adds that "Generally, it is best to record transactions on a daily basis."

The IRS lists the supporting documents to keep:

  • Income: documents showing amounts and sources, such as deposit information, receipt books and invoices.
  • Expenses: documents that "identify the payee, the amount paid, proof of payment, the date incurred," and describe what was bought. Think chemical orders, fuel, repairs, insurance and software.
  • Assets: for equipment and vehicles, when and how you acquired them, the purchase price, improvements, depreciation taken, how you used them and how you disposed of them.
  • Employment taxes: if you have employees, keep these records for at least four years.

How long to keep records

The IRS page How long should I keep records? says you generally keep records that support an item on your return "until the period of limitations for that tax return runs out." For income tax returns it lists:

  • 3 years, if the 6-year and indefinite situations below do not apply.
  • 3 years from filing or 2 years from paying the tax, whichever is later, if you file a claim for credit or refund.
  • 7 years if you file a claim for a loss from worthless securities or a bad debt deduction.
  • 6 years if you leave out income that is more than 25% of the gross income shown on your return.
  • Indefinitely if you do not file a return or file a fraudulent one.
  • Employment tax records for at least 4 years after the tax becomes due or is paid, whichever is later.

For property such as a truck-mount or van, keep records until the period of limitations expires for the year you dispose of it. The IRS also says to keep copies of filed returns, and notes that "your insurance company or creditors may require you to keep them longer than the IRS does."

Track vehicle use

Under IRS Topic no. 510, Business use of car, if a vehicle is used for both business and personal purposes, "you may deduct only the cost of its business use." You use either the standard mileage rate or actual expenses (gas, oil, repairs, tires, insurance, registration fees, licenses, and depreciation or lease payments for the business share). Business parking fees and tolls are deductible separately under either method.

The standard rate has conditions. One is that you must not operate "five or more cars at the same time, as in a fleet operation," which matters as your crew grows. For a vehicle you own, you must choose the standard rate in its first year of business use.

The IRS standard mileage rates page lists two business rates for 2026: 72.5 cents per mile for January 1 to June 30, and 76 cents per mile for July 1 to December 31. Check that page each year.

Either way, keep a log. Publication 463 (for 2025 returns) says to record "the mileage for each business use, and the total miles for the year," along with the date, destination and business purpose, "at or near the time." A weekly log counts as timely. It also explains when trips from home count as commuting, which is generally not deductible.

Estimated tax and self-employment tax

Form 1040-ES describes estimated tax as the way to pay tax on income not subject to withholding, such as self-employment earnings. The IRS estimated taxes page says sole proprietors, partners and S corporation shareholders "generally have to make estimated tax payments if they expect to owe tax of $1,000 or more when their return is filed." Those payments cover self-employment tax too.

The IRS self-employment tax page says it applies if your net earnings from self-employment were $400 or more, at a rate of 15.3% (12.4% social security, 2.9% Medicare). For 2026, the social security part applies to the first $184,500 of combined wages, tips and net earnings.

The 2026 Form 1040-ES lists four due dates: April 15, 2026; June 15, 2026; Sept. 15, 2026; and Jan. 15, 2027. Per the IRS pay-as-you-go page, a date that falls on a weekend or legal holiday moves to the next business day.

Paying too little or late can bring a penalty "even if you are due a refund." The IRS says most taxpayers avoid it by owing less than $1,000 after withholding and credits, or by paying at least 90% of this year's tax or 100% of the tax on last year's return, whichever is smaller; special rules apply to higher-income taxpayers. You may pay weekly or monthly, "as long as you've paid enough in by the end of the quarter."

Your state may have its own income tax and estimated payments, so check its tax agency. The IRS state government websites page links to each state's tax and business information.

Sales tax records, and when to get help

Sales tax on carpet cleaning is set state by state. The CarpetOS guide to sales tax on carpet cleaning by state shows how to find your state's rule and records.

The SBA's manage your finances guidance says "Consider hiring a certified public accountant (CPA), bookkeeper, or using an online service," noting a bookkeeper "can provide basic day-to-day functions at a lower cost" without a CPA's formal accounting education. Good moments to ask: before your first hire, a vehicle purchase or a change of structure. Publication 583 notes that how an LLC elects to be treated for tax purposes "will determine what taxes you must pay and what forms you should use to pay your taxes."

The IRS says "Anyone can be a paid tax return preparer as long as they have an IRS Preparer Tax Identification Number (PTIN)," and offers a directory of preparers with credentials to check qualifications.

CarpetOS handles quotes, invoices, payment links and overdue reminders. It does not do accounting or tax filing, so keep your books and bank records alongside it.

Quick checklist

  • Open a business checking account and run every job payment and expense through it.
  • Keep invoices, receipts and statements, organized by year and type.
  • Log business miles at or near the time, weekly at the least.
  • Keep records at least 3 years, employment tax records at least 4, and asset records until the limitations period ends for the year you dispose of them.
  • Set money aside for income and self-employment tax, and diary the four due dates.
  • Check your state's income tax and sales tax rules.
  • Talk to a bookkeeper or tax professional before big decisions.
