Council Tax Reduction on Maternity Leave: What Changes and What Doesn't

Going on maternity leave usually means a drop in income — and that can change your Council Tax Reduction entitlement. If you're currently receiving CTR, or you've never applied because you assumed you earned too much, maternity leave is the moment to look again.

Why Maternity Leave Triggers a Change

Council Tax Reduction is means-tested. When your income drops — from full salary to Statutory Maternity Pay (SMP), Maternity Allowance, or unpaid leave — the gap between your income and your Applicable Amount narrows or disappears. That means a higher CTR award.

Statutory Maternity Pay or Maternity Allowance can be lower than your normal earnings, so check the income figures Newham uses against your current award and payslips.

If You Already Receive CTR

You are legally required to report the change in income to your council within 21 days. Tell the DWP about changes to Universal Credit, but also notify the council separately — the two systems are not linked for CTR purposes.

When you report the income drop, the council recalculates your CTR using your new, lower income. The result should be a higher weekly award and lower council tax instalments.

Remember to report again when your maternity pay ends and you either return to work at your previous salary or move onto a different benefit.

If You Don't Currently Receive CTR

Many working residents never apply for CTR because their salary puts them above the threshold. Maternity leave changes the arithmetic. If your household income during the flat-rate SMP period — combined with your partner's income and any other earnings — is close to or below the Applicable Amount, you may qualify for a partial or even maximum award.

The key parameters in Newham for 2026/27:

• Maximum CTR: 70% of your net council tax bill
• Capital limit: £6,000 for working-age claimants
• Income taper: 30% — every £1 above the Applicable Amount reduces your CTR by 30p
• Lone parent earnings disregard: £25/week (higher than the standard £5 or £10)

The lone parent disregard is particularly relevant if you're a single parent — it lets you keep £25 per week of earnings without it counting toward the means test.

Maternity Allowance vs SMP

Maternity Allowance (for those who don't qualify for SMP through their employer) is treated as income in the means test, but at a lower weekly rate than most salaries. The same principle applies: the lower income may qualify you for CTR or increase an existing award.

The Timing Matters

Your CTR claim date matters. If you apply for CTR in the early weeks of maternity leave (when SMP is at 90% of earnings), your assessed income will be higher than if you apply during the flat-rate period. The council uses your current income at the point of assessment, so applying during the lower-income period gives a more accurate picture of your actual financial position.

If you've already been on maternity leave for a few weeks before applying, you can request backdating — up to six months for working-age claimants, provided you can show "good cause" for the delay.

What About Shared Parental Leave?

Shared Parental Pay is assessed the same way as SMP — it's treated as income and enters the means test at whatever rate you're receiving. If you and your partner are splitting leave, the council looks at the household's combined income during the period of reduced earnings.
