You need a contractor for a project or ongoing work, and you want to get it right from the start. Paying someone as a 1099 contractor sounds simple, but skipping or botching the paperwork costs you later—penalties from the IRS, state compliance issues, misclassified workers, or scrambled tax records at year-end. This guide walks you through the real steps: getting a signed W-9, setting up your records correctly, understanding sales tax obligations if you’re in Florida, and avoiding the mistakes that trap small-business owners.

Does this apply to your business in Florida?
If you pay any individual or business more than $600 in a calendar year for services—and that person or entity is not your employee—you need to issue a Form 1099-NEC and file it with the IRS. A W-9 is your foundational document: it’s how you collect the contractor’s legal name, tax ID, and certification that they are authorized to work. Without a completed, signed W-9 before you make the first payment, you have no record that the contractor was willing to accept 1099 treatment, and you open yourself to compliance gaps.
Why the W-9 matters before dollar one
A W-9 (Request for Taxpayer Identification Number and Certification) is not optional. It’s your proof that you asked the contractor for their tax ID and their declaration of eligibility. If you hire someone and pay them without collecting a W-9, you can’t issue a clean 1099-NEC later, and the IRS may see you as negligent in your withholding obligations. Moreover, if the contractor disputes their status or the IRS questions your classification, you have no documented agreement. The W-9 also signals to the contractor that you expect them to report this income—it sets expectations upfront.
Step 1: Get a completed, signed W-9 before the first invoice
You need the contractor to fill out and sign Form W-9 (available free from the IRS website) before you send the first payment. The contractor fills in their legal name, address, tax ID (SSN or EIN), entity type (sole proprietor, LLC, S-corp, etc.), and certifies that the tax ID is correct and they are not subject to backup withholding. You sign and date it on your end as well. Keep the original or a scanned copy in a dedicated contractor file—this is your audit protection.
If the contractor refuses to provide a W-9, do not pay them. A refusal is a red flag that they either don’t understand what a 1099 is, are already classified elsewhere (like as another company’s employee), or are trying to hide income. Paying without a W-9 exposes you to IRS penalties and state employment-tax issues.
Step 2: Categorize and document the work and payment
Once the W-9 is signed, set up your records to track what the contractor did, when, how much they were paid, and the payment method. If you use a bookkeeping platform or spreadsheet, categorize the expense correctly. A contractor invoice for services should be coded as a business expense (e.g., “Contractor Services,” “Consulting,” “Repair,” depending on the actual work). Do not lump all contractor work into one vague account; this makes tax time harder and raises IRS questions.
Keep the contractor’s invoice or statement of work alongside the W-9. If there’s a scope of work (e.g., “paint interior walls for $2,500,” not just “contractor payment $2,500”), attach it. This documentation is your defense if the IRS ever questions whether the payment was for legitimate business purposes or whether the contractor should have been classified as an employee.
Step 3: Know your sales tax obligation in Florida if services include materials
Here’s where Florida contractors get tripped up. If the work involves both labor and materials, and the contractor is billing you a lump sum, the entire amount may be subject to Florida sales tax. However, if the contractor separately itemizes labor and materials—and labor is listed on its own line—then only the materials portion is taxable under Florida law. Labor, when separately stated, is not taxable.
Ask your contractor for an itemized invoice that breaks out labor hours and labor rate from the materials cost. If the invoice says “$5,000 for work” with no breakdown, you’re responsible for collecting sales tax on the whole amount if you’re reselling (or if it’s a service like construction). If it says “$3,000 labor + $2,000 materials,” you collect sales tax on the $2,000 only. This distinction is critical if your business is a construction, cleaning, or landscaping operation—or any service that supplies materials to clients.

Step 4: Track 1099 threshold and payment method
Keep a running total of what you pay each contractor during the calendar year. Once that total hits $600 or more, you must issue a Form 1099-NEC by January 31 of the following year. Pay by check, transfer, or documented payment method so you have a clear trail for your records and for the contractor to report on their own taxes.
Some business owners prefer to pay via credit card or PayPal to keep an automatic receipt. That works, but make sure your internal records match your payment platform’s records. Reconcile these monthly if possible, especially if you have multiple contractors.
Step 5: Plan for 1099-NEC filing at year-end
As January 31 approaches, compile all your contractors’ W-9s and match them against your payment records. For each contractor with $600+ in payments, you’ll issue a 1099-NEC. You file a copy with the IRS and one to the contractor. If you have more than one 1099-NEC to file, you’ll also file Form 1096 (a summary cover sheet) with the IRS.
Your CPA or bookkeeper can handle the actual filing, or you can file electronically yourself through the IRS’s FIRE (Filing Information Returns Electronically) system. Either way, the accuracy of your initial W-9 and record-keeping is what makes this process smooth. If the information on the W-9 doesn’t match your records (different spelling of name, wrong tax ID), fix it now while the contractor is still fresh in your mind—not in February when you’re scrambling.
Common mistakes that complicate contractor setup
Paying before collecting the W-9. You send the first invoice payment, and then ask for a W-9 weeks later. By then, you’ve already missed the documentation requirement. The contractor might have lost the form or changed their address. Set a firm rule: no payment without a signed W-9 in hand first. If you’ve already slipped up here, collect the W-9 retroactively as soon as possible and note the date you received it in your file.
Misclassifying a contractor as an employee. You pay a contractor $15,000 a year under the table without a W-9, no payroll withholding, no 1099 at year-end. If the IRS audits you or the contractor’s tax return is flagged, you could owe payroll taxes, penalties, and interest. The IRS uses a multi-factor test (degree of control, duration, integration with your business, exclusivity) to determine worker status. If the person works full-time for you, you direct their work daily, and you’re their only client, they’re likely an employee, not a 1099. Get this classification right at the start.
Not itemizing labor and materials on contractor invoices. Your roofing contractor sends you a bill for $8,000, no breakdown. You have no idea how much is labor versus materials. When you file your Florida sales tax return, you can’t determine the taxable amount, and you either overstate tax (wasting cash flow) or understate it (risking penalties and interest). Require every contractor invoice to itemize labor separately from materials. This is especially critical if you resell the service or materials to your own customers.
Losing or not storing W-9s properly. You collect the W-9, file it somewhere, and in January of the next year when you sit down to issue 1099s, you can’t find it. You scramble to recreate information, leading to errors on the 1099-NEC form. Use a simple system: a dedicated folder (digital or physical) for each contractor that contains the W-9, all invoices, payment records, and scope of work. Review this folder quarterly so you catch discrepancies before tax time.
Using a platform to organize contractor data
If you manage multiple contractors or have transactions spread across invoices, bank transfers, and credit cards, organizing this data manually becomes error-prone. A bookkeeping platform that categorizes transactions automatically and tracks contractor payments can save you hours at year-end and reduce the risk of missing a threshold or losing documentation. Tools like Outsourcing Processing’s platform can help you organize contractor expenses and prepare reports that your CPA uses to issue 1099s accurately.

Frequently Asked Questions
What if the contractor asks me not to issue a 1099?
You still must issue it if the threshold ($600+) is met. The 1099-NEC is a legal filing requirement, not a courtesy. The contractor’s discomfort with reporting their income doesn’t change your obligation. If they claim they want to keep things informal or off the books, that’s a compliance red flag for both of you. Document the conversation, issue the 1099 on time, and let your CPA know the situation. If the contractor later misreports income or gets audited, the 1099 you filed protects you.
Do I need a contract with a contractor, or is the W-9 enough?
A W-9 establishes tax identity, not scope of work or payment terms. A simple statement of work or service agreement (even a one-page email confirmation) that describes what the contractor will do, timeline, and payment is recommended. This protects you if a dispute arises about deliverables. The W-9 + statement of work together form your documentation package. Your CPA or a template from your state’s small-business resource site can help you draft a simple one.
What happens if I issue a 1099-NEC with wrong information?
If the contractor’s name, address, or tax ID is incorrect on the 1099-NEC, file an amended Form 1099-NEC (Form 1098-C or corrected 1099-NEC instruction) as soon as you discover the error. The longer you wait, the more problems it causes for the contractor’s tax filing and your IRS relationship. This is why storing and reviewing the W-9 carefully before issuing the 1099 is critical—catch errors while you still have time to fix them.
If a contractor is an LLC, do I still collect a W-9?
Yes. Even if the contractor operates as an LLC, partnership, or sole proprietorship, you collect a W-9 with their entity name and EIN (Employer Identification Number). This confirms their legal structure and tax ID. The process is identical; the W-9 simply reflects that the contractor is an entity, not an individual. Verify that the name and EIN on the W-9 match any contracts or invoices the LLC sends you.
Can I set up a 1099 contractor in Florida without worrying about state income tax withholding?
Florida has no state income tax, which simplifies your withholding obligations compared to many other states. However, you still must issue the federal 1099-NEC and comply with Florida sales tax if your business is subject to it. Make sure your contractor understands they’re responsible for their own federal self-employment tax, federal income tax, and any other state taxes if they work in multiple states. Provide them a copy of the 1099-NEC by January 31 so they can file their own tax return on time.

Set the habit now, not in January
1099 contractor setup is not complicated, but it requires a ritual: collect the W-9 first, itemize invoices clearly, track payments, file the 1099 on time. The businesses that have the smoothest year-ends are the ones that built this habit into their first contractor hire and never deviated. Start with your next contractor payment—make the W-9 your first step, not your afterthought. Your future self and your CPA will thank you.
