Offaly Differential Rent Calculator

What makes the Offaly scheme different

Offaly County Council uses a 22% primary rate paired with a €70 disregard for single-earner households and a €110 disregard where there are two earners in the home.

The two-disregard structure is intended to recognise that a household with two working adults faces higher fixed costs than a single-earner household on the same combined income, and it produces a noticeably gentler tax-on-rent profile than the single-disregard schemes in Laois and Westmeath.

A two-earner Offaly household with a combined €600 a week pays around €108, against €127 in Westmeath at the same combined income. The €10 per-child deduction is among the higher figures in Ireland and applies cleanly to the assessable income calculation.

Subsidiary earners face the same 22% rate above their own €70 disregard, capped at €25 a week per earner, which is mid-range for the Midlands.

The minimum weekly rent steps with property size, €25 for two-bedroom homes and €30 for three-bedroom and larger, an unusual feature that reflects the substantial proportion of older two-bed semi-detached stock in the Tullamore and Birr estates.

The maximum rent is set by reference to the original construction cost of each property, which means newer Offaly developments carry a higher rent ceiling than older estates. The scheme has been in place since September 2022.

What to bring to a Offaly rent review

Offaly 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 Offaly-specific points worth knowing in advance.

Understanding the Offaly 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 Offaly County Council scheme summarised on this page reflects the rules currently in force and last reviewed in September 2022.

Under the Offaly scheme, the primary earner in a household contributes 22.0% of their assessable income each week toward rent, after the first €70.00 of weekly income has been disregarded.

The minimum weekly rent is set at €25.00, 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.

Offaly, 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; Offaly 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.

Offaly charges subsidiary earners at 22.00% of their income once a disregard of €70.00 a week has been applied, and the contribution from each subsidiary earner is capped at €25.00 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 Offaly in writing, usually within 14 days, so the rent can be recalculated.

Dependent children reduce the assessable income figure. Offaly applies a deduction of €10.00 per child per week. The deduction normally applies up to and including the child's 18th birthday, and beyond that for full-time students in approved third-level education up to 23.

Some councils extend the deduction for children with disabilities; this is worth raising directly with the housing officer where it applies.

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 Offaly 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 Offaly 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 Offaly.

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 Offaly, 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 Offaly 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.
