The law is changing
Since 6 April 2026, sole traders, including freelancers, whose qualifying income was over £50,000 in the 2024/25 tax year have been legally required to keep digital records and send quarterly updates to HMRC.
From 6 April 2027, that expands to qualifying income over £30,000 on the 2025/26 return. From 6 April 2028, it expands again to qualifying income over £20,000 in 2026/27.
Most people hear the word tax and start to stress. FreelanceOS makes these changes feel simple.

FreelanceOS is the business operating system for UK freelancers and sole traders.
Your clients, projects, tasks, documents, invoices, expenses and tax records all live in one connected place.
It brings the work you do and the admin behind it into the same system. Plan projects, manage client work, create documents, send invoices, track expenses and keep your tax records organised without rebuilding the same information across different apps.
Add something once. Keep the context everywhere.

Meet Flo
Flo learns your clients, your numbers and your rhythm. It connects the dots while you get your time back.
Just say the word
“Invoice Solace for £1,000.”
“Who's my best paying client?”
“How do I win more work?”
Everything in FreelanceOS flows through Projects. A project can be a client you're working with, a campaign you're running, or a goal of your own. Your tasks, documents, invoices and clients all live inside it, in one living workspace, and it's how Flo understands what you need.
Tasks
Natural language input. Time-aware scheduling. Tasks live inside projects, so nothing floats untethered. Flo keeps the rhythm.
Documents
Proposals, notes, briefs. Tagged by project, always searchable. Everything that needs to leave your head and reach the world.
Invoices
Create invoices. Track income. See what's owed. Linked to the project they belong to. Your financial picture without the gymnastics.
Clients
Every client connects to their projects, their invoices, their history. Flo remembers the context so you don't have to.
One system for
every version of you.
Built for the work
Your invoices, income and expenses stay connected, so getting organised for tax does not mean rebuilding your business at the end of the year.
Digital records
Keep your self-employment income and expenses organised digitally throughout the year, instead of assembling everything when a deadline arrives.
Reconciliation
Upload your bank statement and reconcile transactions in one place — money in matched to invoices, money out filed under a business category. Your data stays yours.
Tax as you go
FreelanceOS estimates a sole-trader set-aside from your records, so you have a planning number to review long before January.
