Gig Contract vs Employment Contract vs Sole Trader: What's Best for a Team of 5–20?

You’re hiring your fifth developer — and suddenly realize the old “employment or sole trader?” question is outdated. Since 2022, there’s a third option. And it changes the math entirely.

On a UAH 500,000/month payroll, the gap between formats is UAH 65,000 every month. Nearly UAH 780,000 (~$19,500) a year. Money that either goes to the state budget or stays in your team.

Three formats exist side by side: a standard employment contract under Ukraine’s Labor Code (KZpP), an agreement with a sole trader (FOP) in tax group 2 or 3, and a gig contract for Diia City residents. Each runs on its own rules — and each carries its own consequences when those rules get broken. Let’s be direct about it, without the usual “each option has pros and cons” non-answer.

# What each hiring format actually costs the employer

An employment contract at UAH 50,000 gross costs the employer UAH 61,000 a month. That’s a fact many founders discover only after the first hire.

The 22% Unified Social Contribution (USC) alone adds UAH 11,000 on top. Add HR time for administration, holiday pay reserves, and sick leave coverage — and the true cost of one person easily hits UAH 65,000–68,000 when the payslip shows “50k.”

A FOP (sole trader) group 3 agreement looks cheaper. No employer USC, no holiday reserves. The company transfers the fee with no deductions — so that same UAH 50,000 lands almost in full with the contractor. The FOP handles their own 5% income tax and USC (UAH 1,430/month in 2026).

But a gig contract? Nearly identical in cost to a FOP arrangement — with the tax legitimacy of an employment contract. According to Ukraine’s Ministry of Digital Transformation, USC under a gig contract is calculated not on the full fee but only on the minimum insurance base. In 2026, that’s UAH 1,430/month per person. Fundamentally less than the UAH 11,000 USC on a UAH 50,000 employment salary.

So: gig contract and FOP are close in cost to the business — but the gig contract eliminates a tax risk the FOP arrangement carries permanently.

# What is a gig contract in Diia City and who can sign one

A gig contract is an agreement with an individual governed not by the Labor Code but by a dedicated section of Law No. 1667-IX. It came into force in December 2021.

The gig contractor is not a staff employee. But they get: 24 calendar days of paid leave per year, paid sick leave, and working-hour limits agreed in the contract. Termination is also faster than standard employment — no two-month notice period required.

There’s one hard condition, though: the company must be a Diia City resident. That requires meeting three criteria simultaneously:

• 90% of revenue from IT products or services;
• 9 or more staff or gig contractors on the books;
• Average rate of EUR 1,200/month (or equivalent) per contractor.

A 5-person startup below the revenue threshold won’t make the registry. That’s the honest answer to “why doesn’t everyone switch to gig contracts?”

# FOP reclassification risks: when the tax authority comes knocking

Here’s the conversation I least enjoy having with clients: “We’ve had everyone on FOP contracts for three years and it’s been fine.” Fine — until they check.

Ukraine’s State Tax Service applies reclassification criteria from Article 21 of the Labor Code and tax guidance issued in 2023–2024. If three or more of the following indicators apply, the relationship is classified as employment:

1. Single client — 75%+ of the FOP’s income comes from one company.
2. Fixed schedule — the contract specifies working hours or office attendance.
3. No subcontracting — the FOP personally performs all tasks without engaging others.
4. Integration into the production process — the FOP uses company tools, a corporate laptop, a corporate email address.
5. Regular, not project-based pay — a fixed monthly amount with no link to a specific deliverable.

The consequences of reclassification: 22% USC back-assessed for the entire relationship period, plus a fine of 10x minimum wage — UAH 80,000 (~$2,000) per de-facto employee. A company with five FOPs in a high-risk arrangement could face UAH 400,000 (~$10,000) in fines alone, before any underpaid contributions.

And this isn’t hypothetical. According to Ukraine’s State Tax Service, the number of labor relations audits rose 34% in 2024 compared to 2022. Wartime is not a shield from tax inspections.

If your FOP works only for you, in your office, on your schedule — that’s employment. Calling it something else is a choice with a predictable ending.

# Employment contracts: when you still need one

An employment contract isn’t the enemy. For part of the team, it’s the only sensible choice.

You need one in three situations: when a staff member works with government bodies and needs official labor status for a visa or mortgage; when the company isn’t in IT and can’t qualify for Diia City; and when the role involves HR managers, accountants, or lawyers with access to financial records — where FOP arrangements are particularly risky from a compliance standpoint.

An employment contract also gives the company protection that FOP agreements don’t: disciplinary accountability and financial liability for damages caused by the employee. Termination is harder — but so is losing a key developer with no legal recourse.

For the back-office of a 5–20 person team, an employment contract is generally the right call. For technical specialists, a gig contract or a carefully drafted FOP agreement works better.

# Choosing the right format for a team of 5–20

There’s no single answer. But there is a working logic.

Team of 5–8, non-IT company. Gig contracts are off the table. You’re choosing between FOP and employment. Use employment contracts for back-office roles (accountant, operations manager) and FOP agreements for developers — but only if the contract clearly describes project-based work, the contractor genuinely works with multiple clients, and that’s verifiable.

Team of 9–15, IT company, 90%+ revenue from products. Diia City is your path. A gig contract eliminates tax risk and gives contractors guarantees that build loyalty. According to dou.ua’s 2024 survey, 67% of Ukrainian developers prefer a gig contract over a FOP agreement when compensation is comparable — specifically because of leave and sick pay.

Team of 15–20, mixed profile. A hybrid model: gig contracts for developers and designers, employment contracts for HR, the CFO, and legal counsel. FOP agreements only for external contractors with a genuine multi-client track record.

Here’s my take — and it’s a blunt one: companies that keep everyone on FOP contracts because “it’s cheaper” are saving money today and paying triple tomorrow. That’s not tax optimization. It’s a deferred cash crunch.

# Switching to gig contracts: Diia City conditions in 2026

Becoming a Diia City resident takes 7 to 30 working days. Applications go through the business.diia.gov.ua portal.

Three mandatory criteria at the time of application:

1. IT revenue share — at least 90% of the company’s total income over the past 12 months.
2. Headcount — minimum 9 employees or gig contractors with Ukrainian tax IDs.
3. Average rate — at least EUR 1,200 per specialist per month.

If any criterion is breached during a quarter, residency is suspended. The company exits Diia City — and all gig contracts automatically lose their preferential tax treatment. That’s not a scare story; it’s Clause 14, Article 5 of Law No. 1667-IX.

After receiving residency: reissue contractor agreements as gig contracts and notify contractors of the change in their tax status. The contractor registers in the system themselves — no separate action required from the company.

What you can’t do: transfer employees from employment contracts to gig contracts without their written consent and without formally terminating the employment relationship first. That’s a separate legal process — not an automatic switch.

And if the transition affects your budget structure — it will — the breakdown in 7 Financial Skills for Business Leaders is worth a read. For distributed teams managing gig and employment models in parallel, Airtable for Business in Ukraine 2026 fits neatly on top of a hybrid setup.

# The verdict: three formats, one recommendation

There’s no symmetrical “every option has its merits” conclusion here.

For an IT team of 9+ people with product revenue — a gig contract through Diia City is the best format available today. The tax savings are real, reclassification risk is gone, and contractors get guarantees that actually matter to them. The only barrier is meeting the residency criteria.

For a team under 9 people, or a non-IT company — employment contracts for back-office roles, and carefully structured FOP agreements for contractors who genuinely work with multiple clients.

But FOP as a blanket substitute for employment across the whole team? That’s a ticking clock. The question isn’t whether it goes off. It’s when.
