A referral commission is money paid to someone who sends you a client or a deal, usually a percentage of what that deal is worth or a flat amount agreed in advance. Rates vary widely by industry, from a few percentage points in real estate to recurring monthly payouts in B2B software, and most of them count as taxable income for whoever receives them. This guide walks through typical rates by sector, the four common ways to calculate a commission, what a proper agreement should contain, and a worked example you can copy to set up your own program.

The gist: Referral commissions are a contractual payment, not a gift, so they need a clear trigger event, a written agreement, and a tracking method that holds up if a partner or the tax office asks questions.

What are referral commissions and how are they different from referral fees?

A referral commission is a payment made to a person or a business for sending a qualified lead or a signed client to another business. In plain terms: someone introduces a prospect, the deal closes, money changes hands.

The terms referral fee and referral commission get used almost interchangeably in everyday conversation, but there is a practical distinction worth knowing. A referral fee often implies a one-time, fixed payment for a single introduction, the kind of arrangement you see between two real estate agents or two law firms. A referral commission more often describes an ongoing relationship where a partner sends multiple leads over time and gets paid on a recurring basis, tied to a percentage or a tier structure. An affiliate fee is a cousin of both: it typically applies to online, self-service referrals tracked through a link or a code, often at lower rates because the relationship is less personal and the partner does less hand-holding.

Who pays whom depends on the industry. In real estate, the agent who closes the deal pays a portion of their own commission to the agent who referred the client. In legal and financial services, the professional who takes on the case or the account pays the referring professional. In agencies and B2B services, the company that signs the new client pays the person or company who introduced them, usually once the contract is signed or the first invoice is paid. For a full breakdown of what a fair rate looks like across sectors, see this comparison of referral fee percentage benchmarks.

Two measured data points, to put this in context: a referred customer is on average at least 16 % more valuable than a comparable customer acquired otherwise, and stays longer (about 10,000 customers of a German bank tracked for almost three years) (Schmitt, Skiera and Van den Bulte, Journal of Marketing, 2011). On top of that, a reward does increase the likelihood that a customer refers, especially toward weak ties and for a lesser known brand; toward close ties it works better when part of the reward goes to the person receiving the referral (Ryu and Feick, Journal of Marketing, 2007).

How much is a typical referral commission by industry?

Legal and attorney referral fees are more tightly regulated. Many bar associations allow referral fees between attorneys only when the referring lawyer stays involved in the case or when the fee is disclosed to the client and approved. Rates typically fall between 10 % and 33 % of the fee earned on the case, but a lawyer should always check the specific rule in their jurisdiction before agreeing to anything.

Insurance, mortgage and wealth management referrals often pay a flat fee per qualified lead, somewhere between 50 and 500 dollars or euros, or a percentage of the first-year commission, often in the 10 % to 20 % range. A mortgage broker might pay an estate agent a flat fee each time a referred buyer completes a loan.

Agencies and B2B services tend to be the most flexible.

Industry Typical rate Usual basis
Real estate 20 % to 35 % Percentage of the agent's commission
Legal services 10 % to 33 % Percentage of the fee earned, jurisdiction-dependent
Insurance and mortgage Flat fee or 10 % to 20 % Flat per lead, or percentage of first-year commission
Wealth management 10 % to 20 % Percentage of assets under management fee
Agencies and B2B services 5 % to 15 % Percentage of first invoice, sometimes recurring

How is a referral commission calculated?

A referral commission is calculated using one of four structures: a percentage of revenue, a flat amount, a recurring payment, or a tiered rate that increases with volume.

Percentage of revenue

This is the most common method. The partner earns a fixed percentage of whatever the new client pays, either on the first transaction only or on every transaction for a set period.

Flat amount

A flat fee is simpler to administer and works well when deal sizes vary a lot or when the value of the introduction is hard to tie to revenue. A builder might pay a flat 200 euros for every referred client who signs a renovation contract, regardless of the project's final price.

Recurring commission

Some businesses, especially subscription-based ones, pay a recurring commission for as long as the referred client remains active.

Tiered commission

A tiered structure increases the rate as a partner refers more clients. This rewards your most active referral partners without overpaying occasional ones.

Is a referral commission taxable?

Yes, in almost every country a referral commission counts as taxable income for the person or business that receives it. Whether it is also deductible or reportable for the payer depends on local rules, which is why this is a conversation to have with an accountant rather than a guess to make alone.

For the receiver, a referral commission is generally treated as ordinary income, whether it comes as a one-time payment or a recurring one. If the recipient is a sole trader or freelancer, it usually gets added to their business income and taxed accordingly. If it is paid to an individual who does not run a business, many countries still require it to be declared, sometimes under a specific threshold that triggers a reporting obligation for the payer.

The payer's responsibility varies. In some countries, a business paying referral commissions above a certain amount must issue a tax form to the recipient and report the payment to the tax authority, similar to how contractor payments are handled. In others, the responsibility to declare falls entirely on the recipient, and the payer only needs to keep records in case of an audit. Common differences to check with an accountant include whether the commission is subject to VAT or sales tax, whether a withholding tax applies to cross-border payments, and whether there is a minimum threshold below which no reporting is required. None of these rules are universal, so treat any specific percentage or threshold as something to confirm locally rather than something to assume.

What should a referral commission agreement include?

A referral commission agreement should define exactly when the commission is earned, how and when it gets paid, and what happens if a deal falls through later. Without these three elements in writing, disputes are almost guaranteed.

The trigger event is the single most important clause. Does the commission become due when the lead is introduced, when the prospect signs a contract, when the first invoice is paid, or only once the client has been active for a minimum period? Vague wording here is the single biggest source of conflict between a business and its referral partners.

Payment terms and deadlines should state the exact percentage or flat amount, the currency, how the partner gets paid (bank transfer, PayPal, platform payout), and the deadline, for example within 30 days of invoice payment. A clawback clause explains what happens if the client cancels, refunds, or defaults shortly after signing: does the partner keep the commission, or does the business reclaim it? A dispute clause states how disagreements get resolved before anyone considers legal action. For the full list of clauses a solid contract needs, see this breakdown of referral partner agreement clauses.

Step-by-step: how to set up a referral commission program from scratch

Setting up a referral commission program takes five steps: define the trigger and rate, draft the agreement, invite partners with a tracking link, approve and pay on schedule, and review the numbers regularly.

  1. Define the trigger and the rate. Decide whether commission is earned at signed contract or at first payment, and pick a structure (percentage, flat, recurring, or tiered) that matches how your business actually makes money.
  2. Draft the agreement. Put the trigger, the rate, the payment deadline, and the clawback clause in writing, even for informal relationships with friendly contacts.
  3. Invite partners with a tracking link. A shared link or code lets you attribute each lead to the right partner without relying on memory or manual notes. The Referaly Finder directory is one way to also discover new referral partners in your industry rather than starting from zero contacts.
  4. Approve and pay on schedule. Set a recurring date, weekly or monthly, to review new referrals, confirm the trigger event happened, and release payment. Delays here are the fastest way to lose a partner's trust.
  5. A former client refers a new prospect who signs a 6,000 euro project. The agency invoices the client, the client pays, and 15 days later the agency transfers 600 euros to the referring partner. If that same partner sends three more clients over the year at similar values, the agency can use a referral ROI calculator to check whether the commission paid out is still smaller than what a comparable advertising campaign would have cost to bring in the same clients.

Common referral commission mistakes to avoid

The three most common mistakes are an unclear trigger event, no written agreement, and tracking everything manually in a spreadsheet.

An unclear trigger event causes arguments the moment a deal takes longer than expected to close, or when a client pauses a project and restarts it months later. Writing down the exact moment commission is earned, before any money changes hands, avoids most of this.

No written agreement is still surprisingly common between professionals who know each other well, and it is exactly where things go wrong. A verbal promise of "I'll take care of you" rarely survives a disagreement about whether a lead counts as "referred" or "walked in on their own."

Manual tracking in spreadsheets works for the first few referrals, then breaks down once a business has more than a handful of active partners. Referrals get forgotten, payments get delayed, and partners lose confidence that they are being tracked fairly. This is the exact gap tools built for referral partner tracking are meant to close, so that every introduction, every stage of the deal, and every commission owed stays visible without manual chasing.

As Dave Balter, founder of the word of mouth marketing agency BzzAgent, put it, referral relationships last "when people feel the system is fair and transparent, not when the check is simply bigger." Clarity, not generosity, is what keeps referral partners active over time.

Frequently asked questions

How much commission does a referral agent typically make?

A referral agent typically makes between 10 % and 35 % of the fee or commission earned on the referred deal, depending on the industry.

How much is a typical real estate referral fee?

Is a referral commission taxable?

Yes, a referral commission is almost always taxable income for the person or business receiving it, whether it is a one-time payment or recurring. Reporting obligations for the payer vary by country, so check the specific rule with a local accountant before assuming a threshold applies.

How much should an attorney referral fee be?

An attorney referral fee commonly falls between 10 % and 33 % of the fee earned on the case, but many bar associations require the referring lawyer to stay involved or disclose the arrangement to the client. Always check the specific ethics rule in the relevant jurisdiction before agreeing to a percentage.

What's the real difference between a referral fee and a referral commission?

A referral fee usually refers to a one-time, fixed payment for a single introduction, common between two independent professionals like estate agents or lawyers. A referral commission more often describes a recurring or percentage-based payment tied to an ongoing partnership where a partner sends multiple leads over time.

Referral commissions work best when they are written down, tracked consistently, and paid on a predictable schedule, not when they rely on memory and goodwill. If you are ready to move past spreadsheets and set your rates, your trigger events, and your payouts in one place, Referaly lets you build that program and find new referral partners through its directory in a single tool.
