CIS mortgages: borrowing on your CIS pay

Paid under the Construction Industry Scheme? You’re self-employed for tax, but many lenders can work from your CIS pay rather than your tax returns: your last 12 months’ earnings, or your last 3 months’ gross pay, less materials. They usually count all of it.

CIS mortgage calculator

What could you borrow?

Complete a few basic details to get an idea of the maximum mortgage lenders could offer on your CIS pay. Choose the last 12 or 3 months, and take off anything paid for materials.

How you work

Your CIS pay

From your CIS payslips or statements. Lenders usually use all of it.

Take off anything paid for materials: lenders only count your labour.

Compare with your tax returns optional

Your net profit from your SA302s.

Other income optional

A job as well, a pension, benefits, maintenance or rental income.

As a guide, you could borrow up to
–
Add your CIS pay to see what you could borrow.

This is a guide, not a mortgage offer. Whether you qualify, and how much you could borrow, depends on each lender’s criteria, your credit history, your outgoings, your deposit and the property. We’ll confirm a real figure with you before anything is applied for.

How lenders work it out

Your CIS pay, or your tax returns

CIS statements show what you earned before your business costs, so working from them usually gives a higher income than the net profit on your tax returns.

Last 12 months

A year’s CIS earnings

What you’ve been paid under CIS over the last 12 months, less anything paid for materials.

Last 3 months

3 months’ pay × 4

Your gross pay over the last 3 months, less materials, turned into a yearly figure. Useful if you haven’t been on CIS for a full year.

Tax returns

Like any self-employed

Some lenders treat CIS workers as self-employed and use the net profit on your tax calculations (SA302s), usually averaged over two years.

Want to see if you’d qualify?

A CeMAP-qualified advisor will look at your CIS statements and tell you which lenders will use them. There’s no obligation.

Worth knowing

  • Lenders that use your CIS pay usually count all of it, after taking off materials.
  • With those lenders you often don’t need your tax calculations and overviews at all.
  • Some lenders assess CIS workers under their employed criteria, which can open up better rates.
  • Been working under CIS for a while but not filed a tax return yet? Some lenders will still help.

A worked example

A subcontractor paid £11,700 gross under CIS over the last 3 months, including £700 for materials, with £30,000 net profit on their last tax return.

CIS pay: (£11,700 − £700) × 4£44,000 a year
At up to 5.5×up to £242,000
Tax return net profit£30,000 a year
At up to 5.5×up to £165,000
Extra, up to£77,000

An illustration. Each lender sets its own multiples, which also depend on your loan to value, credit history and outgoings.

Need to borrow more than this shows?

If your tax returns undersell what you earn, we’ll tell you which lenders will work from your CIS pay instead.

Barrett Mortgages Were Fantastic

Barrett Mortgages were fantastic at getting us the best mortgage deal possible and our circumstances were very complicated with my husband being self-employed. Despite this they didn’t give up, and kept us well informed throughout the whole process. Nothing was too much trouble from start to finish. We will definitely be using this company again in the future and recommend to anyone looking for a mortgage broker. You will not be disappointed. Fantastic service, special thanks goes to Ben.

Darren Was On Point

My wife and I recently used Darren at Barrett Mortgages and I couldn't recommend them highly enough. We're first time buyers so knew very little about the process and Darren always took the time to answer any of our questions and everyone at Barrett was super helpful. We didn't think it would be possible to get a mortgage as I'm a freelance musician but they were able to get us a brilliant deal. Would highly recommend Darren and the team for anyone needing a mortgage.

CIS mortgage questions

Can I get a mortgage on CIS payslips?
Yes. Many lenders will work out your income from your CIS pay instead of your tax returns, using your last 12 months’ earnings or your last 3 months’ gross pay, less materials.
Why is my CIS pay higher than my tax return?
Your CIS statements show what you were paid before your business costs. Your tax return shows net profit, after those costs. Lenders that use CIS pay start from the higher figure, after taking off materials.
Do I need a tax return?
Not with lenders that use your CIS pay. Others treat you like any self-employed applicant and ask for your tax calculations (SA302s) and tax year overviews.
How long do I need to have worked under CIS?
Some lenders want 12 months of CIS history; others will work from your last 3 months. We’ll know which fit before anything is applied for.
What paperwork will I need?
Your CIS payslips or monthly statements, recent bank statements showing the pay coming in, ID and proof of your deposit. If we go by your tax returns instead, your SA302s and tax year overviews.
