What makes the Mayo scheme different

Mayo County Council operates one of the simplest differential rent schemes in Ireland, with a single flat 16% rate applied to assessable income from the first euro.

There is no disregard, no child deduction, and no maximum cap, which makes the rent letter straightforward to predict but also means the household has no buffer against income changes.

A Mayo tenant on €350 a week pays €56, against €42 in Fingal under its 12% flat rate and €46.50 in Waterford under the graduated band structure.

The 16% rate is calibrated to land most working-tenant rents in the €40 to €100 range, which is roughly comparable to the Border and West regional norms, but the absence of a child deduction makes Mayo a relatively expensive council for larger families compared to Roscommon's €10 deduction or Cavan's €7.

The minimum weekly rent of €30 binds for households on the lowest social welfare payments and is reached at an assessable income of just under €190 a week. Subsidiary earners pay 10% of their income capped at €20 a week, which is consistent with the regional pattern.

The scheme has been stable since January 2018, and Mayo councillors have indicated that any 2026 to 2027 review would focus on introducing a child deduction rather than altering the rate, in response to consistent feedback from Family Resource Centres in Castlebar and Ballina.

How Mayo's differential rent scheme works

16% flat rate of assessable income with no threshold or disregard. Minimum €30/week, no maximum cap. No child deductions. Subsidiary earners pay 10% capped at €20/week.

What a Mayo tenant would pay at different income levels

Calculated from Mayo's published scheme rules above, for a single tenant with no dependants. Your actual rent depends on household composition, dependants, subsidiary earners, and any allowable deductions.

What to bring to a Mayo rent review

Mayo typically reviews differential rent annually, and any change in household composition or income should be reported to the housing section within 14 days of the change. The documentation required is broadly the same as other Irish local authorities, with a few Mayo-specific points worth knowing in advance.

Understanding the Mayo differential rent scheme in detail

Differential rent is the system every Irish local authority uses to set rent for social housing tenancies, where the weekly amount you pay is tied to your household income rather than to the open-market value of the home.

The legal foundation sits in Section 31 of the Housing (Miscellaneous Provisions) Act 2009, which gives each of the 31 local authorities the power to design and publish its own differential rent scheme.

The result is that the rent paid by two households with identical incomes can differ from one council area to another, sometimes by tens of euro a week, because the rate applied, the income disregard allowed, the way subsidiary earners are treated, and the minimum and maximum weekly rent are all set locally.

The Mayo County Council scheme summarised on this page reflects the rules currently in force and last reviewed in January 2018.

Under the Mayo scheme, the primary earner in a household contributes 16.0% of their assessable income each week toward rent.

The minimum weekly rent is set at €30.00, which is the figure most households on Jobseeker's Allowance, the State Pension, or Disability Allowance will land on once their assessable income, dependants, and any allowable deductions have been factored in.

The maximum weekly rent is uncapped, which means rent continues to climb in line with income with no upper limit.

Assessable income is one of the most misunderstood terms in social housing, and it is worth pausing on.

Mayo, like every Irish local authority, counts gross wages, salary, and self-employment earnings, together with the bulk of social welfare payments — Jobseeker's Allowance, One-Parent Family Payment, Disability Allowance, Carer's Allowance, the State Pension (Contributory and Non-Contributory), Invalidity Pension, Widow's or Widower's Pension, Working Family Payment, and similar weekly schemes.

Maintenance payments received under a court order are included. Rental income from a sublet, a room let, or a second property is included.

What is excluded varies but typically covers Child Benefit (Children's Allowance), the Fuel Allowance in many cases, the Domiciliary Care Allowance, certain Foster Care Allowances, and the Living Alone Allowance where applicable.

Some councils disregard the first portion of Working Family Payment, and some give a partial disregard for income earned through Community Employment schemes; Mayo publishes a definitive list which should be consulted before submitting an income review.

Household composition matters as much as income. The principal earner — usually the tenant of record — is assessed at the full primary rate.

Any additional adult in the household who earns is treated as a subsidiary earner, and this is where schemes diverge most sharply across the 31 councils. Mayo charges subsidiary earners at 10.00% of their income, and the contribution from each subsidiary earner is capped at €20.00 a week.

The percentage model scales with ability to pay and is generally fairer than a flat charge, but it requires every earner in the household to be assessed individually.

Either way, a household that takes in a working lodger, a returning adult child, or a partner who starts a new job is required to inform Mayo in writing, usually within 14 days, so the rent can be recalculated.

Dependent children reduce the assessable income figure. The current Mayo scheme does not include a per-child deduction; instead, the rates and disregards are calibrated to deliver a comparable outcome for households of different sizes.

If your circumstances have changed because a child has been born, has left full-time education, or has become a registered subsidiary earner, contact the housing section so the file can be reviewed.

Where a deduction applies it is taken off the assessable income figure before the percentage rate is calculated, not off the final rent — a subtlety that becomes important when comparing your council letter against the indicative figures in the table further up this page.

Rent reviews are an annual or biennial fixture in every Irish local authority and Mayo is no exception. The review typically asks tenants to submit recent payslips, social welfare receipts, P60s or end-of-year statements, and any documentation relating to changes in household composition.

Where income has risen since the last review the new rent applies from a specified date, usually the start of the next rent week.

Where income has fallen — for example, after redundancy, the end of Working Family Payment, or the birth of a child — the tenant should request an interim review rather than waiting for the annual cycle; the recalculated rent applies from the date Mayo receives the documentation, not from the date income changed, so prompt notification matters.

Failure to declare a change in circumstance can result in retrospective arrears and, in serious cases, tenancy enforcement.

It is also worth understanding how differential rent fits alongside the other housing supports administered by Mayo.

The Housing Assistance Payment (HAP) is the primary scheme used when a household qualifies for social housing support but is housed in the private rental market; the council pays HAP to the landlord and the household pays a differential rent contribution to the council, calculated using the same rules as council-owned tenancies.

The Rental Accommodation Scheme (RAS) is a longer-term contractual model with private landlords that also uses differential rent for the tenant contribution.

Cost rental, by contrast, is a separate scheme entirely — rent is set as a function of the building's cost, not the household's income, and is delivered primarily through Approved Housing Bodies and the Land Development Agency rather than through the council's general housing stock.

The figures generated by this calculator apply to council and HAP tenancies; cost-rental rents follow a different methodology and are covered on our cost-rental calculator page.

Finally, a note on accuracy. The figures shown in the indicative table and produced by the calculator are estimates calibrated to the published scheme rules.

They are useful for planning — for understanding how a pay rise, a new household member, or a change in welfare payments will affect rent, or for comparing what a household would pay across different council areas.

They are not a substitute for the official rent letter issued by Mayo, which incorporates any local discretion, transitional arrangements, or specific deductions that apply to your tenancy.

If the figure produced here diverges significantly from your council letter, the council letter is correct and the most common reason for divergence is an income source, deduction, or household member that the calculator was not told about.

The housing officer at Mayo can talk you through how the figure was arrived at line by line, and any tenant has the right to request that breakdown in writing.
