Deadlines avoided
Stress-Free start to the year
Clear tax strategy

January's for leads, not loose taxes

start early, file months before deadlines

The tax year runs from 6th April to 5th April each year. Your tax return must be submitted by the following 31st January. Deadline-chasing kills opportunities and causes errors.

UNDERSTANDING SELF ASSESSMENT

What it is and who really needs to file

The3Key keeps you compliant

Self Assessment is Personal Tax to us, helping you separate personal taxes from business taxes. Untaxed income, including dividends and self-employment, are typical reasons for a creative to complete a return.

DEADLINES THAT MATTER

The tax man's three revenue streams

Miss any of these, Pay the price

Taxes alone are enough, avoid unnecessary payments to HMRC. Missed deadlines causes panic, stress and less money in your bank account. The3Key guide you through deadlines.

Sort my return
Late Filing Penalties

An immediate £100 penalty on 1st February, increasing significantly across the next year.

Late Payment Interest

Interest charged at 7.75% per annum on any late payments to HMRC.

Late Payment Penalties

5% of your unpaid tax at 30 days after the due date, occurring again after 6 and 12 months.

Payments on Account only feel early when there's no plan

Payments towards the current tax year are never early, they're still delayed.
Implementing The3Key's unbreakable tax habits ensures they'll never catch you out again.

How it works?

You don't like tax, but we do

Probably true, so let's make it easy

Request information

We ask for some details from you. You provide us with what we request, leaving us to kickstart what we do best.

Check what's sent

We know your circumstances as good as you. Strange, right? We'll tell you if information is missing.

Data Review

Errors exposing you and opportunities left on the table. We accept neither and ensure all is as expected.

Prepare the return

It'll have been through an internal two-stage checking process, but you'll need to review and sign it.

Submit it

We'll submit the return and you'll pay what's owed using the payment details we provide.

Relax

You'll relax and we'll do the same. We don't find deadlines fun, either.
